A new type of glass...strong and flexible


"New Kind of Glass Will Bend but Does Not Break"

by

Kimberly Ruble

January 29th, 2014

LIBERTY VOICE

Researchers have created a brand new type of extremely strong glass that bends but will not break. It was inspired by the mechanisms of natural structures like seashells. McGill University examiners were able to increase the sturdiness of glass. Now, if the glass is dropped, it will only bend and become slightly out of shape, stated a news release from the university.

Mollusk shells are made out of over 95 percent chalk. This makes them extremely brittle in their purest forms, explained Professor François Barthelat, but something like nacre or mother-of-pearl, which covers the inner side of shells, is made up of minuscule tablets, which are similar to very tiny Lego blocks. It is known to be very tough and strong, which is why scientists have been learning about its construction for nearly the past twenty-five years.

Researchers have long attempted to make nacre in the lab, but it has been something of a challenge. It was like trying to create a Lego wall with minute building tablets. This was not the easiest thing to do. So instead, Barthelat and his group decided to examine the interior weaker edges of nacre and then they used lasers to carve various networks of mini cracks in glass slides so they could make similar fragile boundaries. The results ended up being dramatic.

The research group was able to successfully amplify the durability of glass microscope slides over 200 times by constructing micro cracks through their various surfaces. The researchers were able to keep the cracks from spreading and growing larger by filling up the cracks with polyurethane. This ended up being only a precaution and was never a necessity, stated the news report.

Some of the benefits of the stronger glass could be that it is used in the building of eye glasses, bullet proof windows or maybe even put into the screens of smartphones. This glass will be extremely practical due to its extreme hardness, transparency, chemical resistance and its lasting durability. Everything about this new type of glass appears to be a benefit to society at large. It is also believed that this new kind of glass will be extremely economical, stated Barthelat.

The group thinks that such a technique could be on any size of glass, and they believe the process they did would be very simple to scale to any various glass sheets. What they believe is that now they can strengthen not only glass, but also numerous other materials, by using the micro crack configurations in order to guide any bigger cracks, and during the process grip energy from an impact, stated Barthelat. The team decided to work with glass because they wanted to toy with something that is considered one of the most brittle materials. However, they plan on continuing their work by testing polymers and ceramics in future. The researchers have created a brand new type of strong glass that bends but will not break.

"The Day the Earth Stood Still"...radio adaptations



One of those science fiction offerings that escaped the pale of radioactive creatures that run amuck destroying cities and eating people. The 1951 film was sophisticated and a huge success. Below are two radio adaptations that followed that stared Michael Rennie.

Actor Michael Rennie reprises his role as Klaatu for the radio listening audience. Jean Peters plays Helen Benson. Billy Gray is recognizable as the character of Bobby Benson and Professor Barnhardt.

An alternate view of change...James Burke's "Connections"


Wikipedia...

Connections is a ten-episode documentary television series created, written and presented by science historian James Burke. The series was produced and directed by Mick Jackson of the BBC Science & Features Department and first aired in 1978 (UK) and 1979 (USA). It took an interdisciplinary approach to the history of science and invention and demonstrated how various discoveries, scientific achievements, and historical world events were built from one another successively in an interconnected way to bring about particular aspects of modern technology. The series was noted for Burke's crisp and enthusiastic presentation (and dry humour), historical reenactments, and intricate working models.

The MIT student



"What's it like to study at MIT?"

The technology institute has just been named best university in the world. Lu-Hai Liang finds out what kind of students go there

by

Lu-Hai Liang   

September 13th, 2012

guardian.co.uk

If you are considering studying at the best university in the world, you'd better be prepared to work your socks off. The pace of learning at the Massachusetts Institute of Technology has been likened to "drinking from a fire-hose".

The science and technology university, located in Cambridge, Massachusetts, has just been named number one university in the world in the latest QS league table.

It has a stellar reputation. In fact, if you added up the revenues of companies founded by MIT alumni, it would make the 11th largest economy on earth.

But what do students think of it? The first thing they tell you about is the workload.

"So, MIT is a lot of work. I'm four days into the semester, and I've already handed in two p-sets [problem sets] and a writing assignment, I have two other p-sets and a 20-minute presentation to do, and I have to read All The President's Men by the end of the week," says Amy Guyomard, a third-year maths major.

The institute has become a movie byword for a technical intelligence. Engineering prodigy and billionaire inventor Tony Stark, aka Iron Man, is an MIT graduate. Good Will Hunting, starring a super-brainy Matt Damon, was set on the campus.

Of course, it's very tough to get in. In 2012, just 9% of 18,109 applicants received an offer. Exceptional students are drawn to the institute.

Take Michael Plasmeier. He built GridView, a Facebook app that let users make a photo mosaic using their friends' pictures, when he was 15. The app had 1.3 million installs and made about $16,000 in revenue.

But even he admits that when he first came to MIT, he did "very poorly": "MIT is like bootcamp for your brain. You are given all these hard problems and you need to figure out how to solve them.

Plasmeier, now 21 and a management and computer science student, adds: "Information is not spoon-fed, you need to find your own personal style of learning."

How does the institute pick from the thousands of students that apply? "MIT does not admit purely on test scores," says Michael Colao, who helps co-ordinate admissions to the school from the UK.

He looks for initiative and intellectual curiosity when he interviews potential students. "We look at certain characteristics. Especially how well you collaborate: evidence of being good at working as part of a team. So much of science and technology is now focused on working together."

Colao says there has been a 45% increase in successful applicants from the UK over the past three years. This is in line with other Ivy League colleges such as Harvard and Yale, who have also seen strong increases in applications.

MIT does a lot to minimise competition between students. There is no class of degree, a degree from MIT is just a degree.

Plasmeier stresses that there is huge variety in the student population: "We do have some Good Will Hunting-style people. But we have all types of people. People who like to party. People who like to build roller coasters in front of their dorm.

"MIT is as hard as you want to make it. Just like bootcamp, every day might not be fun, but you come out a lot better than you went in."

Standard PCs are to be fossilized


It was going to happen. Will you miss the external components, mass of wires and cables, the weight, the space it occupies?

"Era of the PC 'coming to a close'"


August 11th, 2011

BBC NEWS

PCs are going the way of typewriters, vinyl records and vacuum tubes, one of the engineers who worked on the original machine has said.

The claim was made in a blog post commemorating 30 years since the launch of the first IBM personal computer.

No longer, said Dr Mark Dean, are PCs the leading edge of computing.

No single device has taken the PC's place, he said, instead it has been replaced by the socially-mediated innovation it has fostered.

While IBM was not the first to produce a personal computer, the launch of the 5150 on 12 August 1981 established standards and a design around which many desktop machines have since been built.

'Powerful impact'

"When I helped design the PC, I didn't think I'd live long enough to witness its decline," wrote Dr Dean, an IBM engineer who worked on the development of the 5150 and owns three of the nine patents for it.

He revealed that he had already moved into the post-PC era as his primary computer was now a tablet.

Dr Dean does not deny that PCs will still be "much used" in the future but are no longer the force for innovation they once were.

Instead, he said, it was the interaction they enable that was driving efficiencies in the workplace and changes in society.

"It's becoming clear that innovation flourishes best not on devices but in the social spaces between them, where people and ideas meet and interact," he wrote.

He added: "It is there that computing can have the most powerful impact on economy, society and people's lives."

Microsoft also marked the anniversary of the unveiling of the 5150 with a blog considering the changes it had brought about.

Instead of talking about a post-PC era, Microsoft's Frank Shaw said the near future should be regarded as a PC-plus era given that more than 400 million personal computers are set to be sold in 2011.

Personal use of computers had spread beyond a desktop machine to game consoles, mobiles and on screens all around us, said Mr Shaw.

The future will see billions more going online and reaping the benefits of closer contact with computers, he said.

The changes initiated by the PC was "just getting started," he added.

"True function of science" poll


What do you think is the true function of science...

Knowledge...2
Technology...0
Both...3
Other...0

Ideally, the true function of science would be the acquisition of knowledge about ourselves and the universe and in many cases that is the primary function but it is also true that science is technology oriented. Think back to the industrial revolution and the importance of "iron" products: From iron beds [that swiftly reduced illness] to agriculture implements such as the iron plow and one can see that technology was aided by the science of metallurgy. Pure scientific research has yielded serendipitous events too: Silly Putty and Teflon. Maybe technology is also an offspring of scientific knowledge and pursued in its own right. One has to admit that some scientific fields are devoid of technology other than using technological tools such as archaeology [Egyptology], astronomy, or exotic physics.

Good reason to keep feet on the ground


"Fuel leak" was what is was called this time...the time before was a fractured fuel valve. Shuttle Discovery has made 35 previous trips and despite retrofitting of the craft, it is getting fatigued and old. It has outlived its function. Fortunately the issues was found while all was on the ground. These are small but significant issues that could abort or totally jeopardize a mission. These missions are but a few hundred miles away but consider a small issue thousands or millions of miles away--then what. It just shows that the mechanicals of any system can fail and cause problems. Best to stay put and let probes, satellites, and unmanned vehicles do the work and take the risks...and done cheaper.

"Launching of Shuttle Postponed Again"

by

Kenneth Chang

March 12th, 2009

The New York Times

KENNEDY SPACE CENTER, Fla. — The space shuttle Discovery will remain on the ground until at least Sunday after a hydrogen leak scrubbed a launch attempt on Wednesday.

"We're in the business of launching, not scrubbing," said Michael D. Leinbach, the shuttle launch director at a news conference Wednesday evening. "But our business requires perfection, and our vehicle was not perfect today."

Technicians will not be able to get a close look at the leak site, near the connection of a vent line to the external fuel tank, until Friday afternoon. The vent line carries away excess hydrogen pressure from the tank and the spacecraft to where it is safely burned.

If the fix is straightforward and quick, shuttle officials hope to launch the Discovery at 7:43 p.m. Sunday.

That will put a time crunch on the mission, because the Discovery has to undock to make room for the arrival of a Russian Soyuz spacecraft, scheduled to launch the next day.

If the Discovery launches Sunday, the mission would be shortened from 14 days to 12 days and one of the planned four spacewalks would be eliminated. If the launch is pushed back to Monday or Tuesday, then the mission would be further shortened with time for probably only one spacewalk.

But that would still accomplish the main objectives of the mission: to deliver the last segment of the space station's backbone truss, a replacement part for a water recycling system and Koichi Wakata, who will join the crew of the space station.

If the Discovery cannot launch by Tuesday, then the mission will likely be pushed to April, with repercussions on the schedule of future shuttle missions and the construction of the space station.

The countdown was proceeding smoothly toward a 9:20 p.m. liftoff under clear skies and full moon. But at about 2 p.m., when the hydrogen tank reached 98 percent full, sensors detected a hydrogen leak at the valve next to the external tank, creating a potential flammability problem. The launch was called off at 2:36 p.m.

Mr. Leinbach said he was 99.9 percent certain that the leak was in the ground equipment and in the shuttle itself, which would make it easier to fix.

"We'll replace what needs fixing," Mr Leinbach said. "We have spares on the shelf."

NASA officials said the leak was not related to three hydrogen gas valves that were inspected after a similar valve broke during the mission of the shuttle Endeavour in November. That failure had no effect on Endeavour’s ascent into orbit, but it did lead to concerns that if a larger piece broke off it could be catastrophic.

NASA postponed the launching of Discovery several times to analyze the valves, and the mission is now a month behind its original launching date.

Through experiments and computer simulations, NASA engineers concluded that it was highly unlikely that a piece from a valve would cause significant damage, and a new magnetic testing method convinced them that the three valves installed in the Discovery were free of cracks.

The Discovery's main cargo is a 45-foot-long, 31,000-pound truss segment with two sets of solar panels.

When the solar panels are unfurled and plugged in, the station’s power-generating capacity will rise to 120 kilowatts from 90 kilowatts.

Also aboard Discovery is a 180-pound replacement part for a water recycling system that the Endeavour took to the space station in November. But a key part in the apparatus that transforms urine into drinkable water failed almost immediately. NASA would like the recycling system fully functional before the expansion of the station of the station crew from three to six, planned for late May.

Liberal education may be dying


Indeed. I have seen the erosion of a liberal education starting many years ago.

"What to learn: 'core knowledge' or '21st-century skills'?"

by

Greg Toppo,

March 4th, 2009

USA TODAY

WASHINGTON--If someone told you that kids need to think critically and creatively, be technologically savvy and work well with others, you'd nod in agreement, right?

At least 10 states have committed to helping students develop these "21st-century skills" in schools, the workplace and beyond. Most recently, officials in Massachusetts committed to working with the Arizona-based Partnership for 21st Century Skills, or P21, the movement's main advocacy group.

But a small group of outspoken education scholars is challenging that assumption, saying the push for 21st-century skills is taking a dangerous bite out of precious classroom time that could be better spent learning deep, essential content. For the first time since the P21 push began five years ago, they're pushing back. In a forum here last week sponsored by Common Core, a non-profit group that promotes "a full core curriculum," they squared off with education consultant Ken Kay, co-founder of the P21 movement.

"It's an ineffectual use of school time," says E.D. Hirsch Jr., founder of the Core Knowledge Foundation and author of a series of books on what students should learn year-by-year in school. He calls the P21 movement "a fragmented approach with uncertain cognitive goals" that could most profoundly hurt disadvantaged children: At home, he says, they don't get as much background as middle-class students in history, science, literature and the like.

Core Knowledge holds that an explicit, grade-by-grade "core of common learning" is necessary for a good education. So, for instance, when fifth-graders learn about Galileo's role in astronomy, they study Italian history and geography as well.

Kay calls criticisms by Hirsch and others "a sideshow that distracts people from the issue at hand: that our kids need world-class skills and world-class content."

Kay notes that virtually all of the industrialized countries the USA is competing with "are pursuing both content and skills."

His seven-year effort has earned enviable support - not only from lawmakers and policy wonks but also from a wide range of corporate backers. His non-profit board of directors boasts members from Intel, Apple, Dell, Adobe, Microsoft, Hewlett-Packard and Cisco Systems, among others, and recent IRS filings show more than $1 million in revenue.

In November, a Massachusetts task force concluded that straight academic content "is no longer enough" to help students compete: It urged state education commissioner Mitchell Chester to add 21st-century skills to curriculum guides and teacher training. That drew a rebuke from The Boston Globe, which editorialized last week that it's "not clear that the approach can be implemented without de-emphasizing academic content."

At its heart, say Hirsch and others, the conflict is about what should happen in a school day: Do kids learn to think by reading great literature, doing difficult math and learning history, philosophy and science? Or can they tackle those subjects on their own if schools simply teach them to problem-solve, communicate, use technology and think creatively?

If you pursue the latter, says University of Virginia cognitive psychologist Daniel Willingham, the rich content you're after inevitably "falls by the wayside." While kids may enjoy working together on projects, for instance, the amount of knowledge they get often ends up being shallow. Furthermore, he says, research shows that many teachers find it difficult to actually teach children to think creatively or collaborate. In the end, they rarely get better at the very skills that P21 advocates.

"If we want our kids to learn how to be better collaborators, we're going to need to teach that," says Willingham, author of the new book Why Don't Students Like School?.

Kay says P21 critics miss the point, offering "a false choice" that won't help U.S. students. He says he hopes to work with critics on incorporating both thinking skills and content into future P21 work.

"We need kids who don't just do what they're told but who are self-directed," he says.

Shot ourselves in the foot?--space debris

ATS 3

Quality engineering and high technology in the satellite business has come with some unexpected woes--longevity and a down turn in satellite demand and production...and space junk.

"With vintage satellites still in orbit, sales are grounded"

Their longevity surprises manufacturers but is bad for business. Upon retirement, they join the mass of space junk.

by

Peter Pae

December 1st, 2008

The Los Angeles Times

If only cars could last so long.

This month, a satellite resembling a shiny spinning drum and orbiting 21,156 miles above Earth celebrated its 41st birthday, astounding engineers and scientists, some of them the children of those who built it.

For years, the satellite has served as an emergency communications link for rescue operations, including the 1985 Mexico City earthquake and the 1980 Mt. St. Helens volcanic eruption. It was supposed to live for only three years when it was launched in 1967. That's when Lyndon B. Johnson was president and bell-bottom pants were the rage.

But the spacecraft, known as ATS 3, isn't alone. Many satellites are operating well past their life expectancy, so much so that manufacturers are hurting from lack of demand for new, replacement satellites.

And those who are buying are asking for guarantees that the new satellites, which can cost as much as $300 million each, will last two to three times as long as the early birds.

"It's a mixed blessing," said John S. Edwards, a space industry analyst for Forecast International. "It says great things about your product, but the satellite-making business is floundering because there are hardly any sales."

Engineers at Boeing Co.'s sprawling satellite-making plant in El Segundo know about the sales drought only too well.

Of the 245 Boeing satellites that have been launched into service, 166 have exceeded their design life. That's more than two-thirds of the spacecraft built at the facility since the 1960s. A third of all satellites have lasted at least twice as long as expected.

That has been the bane of the sales department. With the telecom bust early this decade and consolidation in the satellite services industry, Boeing has sold only one commercial satellite this year. In the late-1990s boom years, it was tallying a dozen orders annually.

Some satellites are living longer because the initial estimates of their longevity were conservative, but many have operated well beyond even the wildest expectations.

"In designing them, we had to take into account all the worst-case scenarios," said Art Rosales, Boeing's director of commercial and civil satellite services and a 29-year veteran of the satellite business. Because most satellites can't be repaired once they're in space, every contingency was considered.

"The worst cases didn't happen, and that has translated to longer life," he said.

Last month, a satellite that was providing an Internet connection for scientists at the South Pole was retired, more than three decades after it went into service. It was designed for a life span of five years.

The satellite's longevity "has been truly remarkable," said Kay Sears, president of a government services subsidiary of Intelsat Ltd., a satellite operator. "No one could have ever imagined that its power supply and batteries could have lasted this long."

In retiring the Marisat F2 satellite last month, Intelsat used up the remaining fuel on board to move it about 125 miles away from its original orbit so it would stay out of the way of other geosynchronous satellites before its power was shut off for good.

So-called GEO satellites orbit at the same speed as the Earth's rate of rotation, allowing them to remain stationary relative to the ground. They are often used for communications, like giant radio transmission towers relaying signals from one place on Earth to another.

Intelsat's Marisat joined a cadre of about 2,000 decommissioned satellites that orbit the Earth as space debris. Some deactivated satellites that orbit a few hundred miles from terra firma eventually burn up in the atmosphere, although fragments of some large satellites have been known to strike Earth.

There are an estimated 800 active satellites, including those built for secret military operations.

With satellites operating much longer than anticipated, customers are expecting more from the new generation of birds, which has led to headline-grabbing setbacks.

Boeing suffered a $1-billion loss a few years ago, after technical problems delayed the delivery of new, more powerful satellites. Some take up to 18 months to build.

The expected life span of the early generation was three to four years. In succeeding generations those expectations rose to seven to eight years and then 10 to 12 years.

"Nowadays, the standard design life is 15 years and everybody expects them to last over 20 years," said Marco A. Caceras, senior space analyst for the aerospace research firm Teal Group Corp.

With even older satellites lasting more than 20 years, some engineers have become emotionally attached to them.

"It's like raising children. They have tantrums and fits," said Erika Roesler-Wong, regional manager for Boeing's customer operations support center in El Segundo, where she helps satellite owners trouble-shoot problems. She's kept an eye on some satellites for nearly 20 years.

When they have to be retired -- many are turned off because they're running out of fuel needed to keep them in a specific orbit -- Roesler-Wong gets a bit choked up.

"It is sad," she said. "But you need to get over it because there are other children around."

ATS-3:

Launched in November 1967, the ATS-3 was still in service more than 28 years later, as of 1995. Among its widest-known achievements are the first full-disk, colour Earth images transmitted from a satellite. Its imaging capability has served during disaster situations, from the Mexico earthquake to the Mount St. Helens eruption. ATS-3 experiments included VHF and C-band communications, a color spin-scan camera, an image dissector camera, a mechanically despun antenna, resistojet thrusters, hydrazine propulsion, optical surface experiments, and the measurement of the electron content of the ionosphere and magnetosphere. Because of failures in the hydrogen peroxide systems on ATS-1, ATS-3 was equipped with a hydrazine propulsion system. Its success led to its incorporation on ATS-4 and ATS-5 as the sole propulsion system.--Wikipedia

LHC and new technologies


Despite the "doomsday" rhetoric the technological possibilities from LHC science are much larger as well as obtaining a better cosmological understanding of the universe.


"Large Hadron Collider to Have "Practical" Spin-Offs?"

by

John Roach

September 12th, 2008

National Geographic News

A multibillion-dollar atom smasher on the Franco-Swiss border may help scientists treat diseases, improve the Internet, and open the door to travel through extra dimensions, according to physicists.

On Wednesday scientists cheered and champagne flowed as the first beam of protons lapped around the Large Hadron Collider's (LHC) 17-mile (27-kilometer) underground tunnel at the European Organization for Nuclear Research.

The collider, the world's largest particle accelerator, was designed to solve big mysteries in science, such as the nature of dark matter and what the universe was like just after the big bang.

The massive machine could also lead to medical and technological advances, some experts argue.

Such potential breakthroughs are often an "ancillary benefit" of big science projects like the LHC, said Lawrence Krauss, a theoretical physicist and author at Arizona State University in Tempe.

Still, Krauss said, these benefits are a misguided way to justify building the atom smasher.

"It's like trying to argue that manned space missions were useful for Tang," he said, referring to the powdered drink mix popularized in U.S. households by NASA in the 1960s.

"Our job as scientists is to explain that these esoteric things [such as dark matter] are not completely unrelated to humanity," he added. "Ultimately, we address the questions of how we got here and what we're made of."

Already Providing Benefits

In the months ahead, scientists will use the LHC to ramp up opposing proton beams to nearly light speed and smash particles together, breaking them into smaller components.

Monstrous detectors will pore through the detritus, helping scientists examine the conditions of the very early universe.

The computer network set up to process the mountains of data generated by each collision is already inspiring spin-offs, noted Andy Parker, a professor of high energy physics at Cambridge University in the United Kingdom, who helped design the grid system.

Parker is also involved with a Cambridge-based company that is using the grid technology, which links together thousands of computers, to better index images on the Internet.

Such a system determines the task to be done, the processing power required, checks for availability, sends the task out, gets it done, and ships it back to the scientist—all while the person sits at a desk.

"I don't have to do anything to achieve [all] that," Parker said.

Technologies developed for earlier atom smashers—such as the Relativistic Heavy Ion Collider that booted up in New York in 2000 and the Fermilab Tevatron started in 1987 in Illinois—are today ingrained in mainstream society, Parker noted.

Positron emission tomography (PET) scans, for example, are common at most major hospitals to make images of the insides of patients' bodies, often to look for cancerous tumors.

The technique stems from general studies of antimatter and the use of particle detectors, Parker said.

And more medical professionals are turning to proton beams similar to those used in the LHC to blast away tumors deep inside bodies.

"What you can do there is send a beam of protons into the patient, which does essentially no damage at all to the tissues on the way in," Parker explained.

"All the damage is done at the point where the protons stop. And by tuning the energy of the protons, you can make them stop inside the tumor."

As scientists working with the LHC learn to better focus and control proton beams, the improvements will likely trickle down to the medical profession, he added.

Faster Than Light

Future spin-offs from the LHC are less certain.

"We don't know what we're going to find out," Parker said.

Though admittedly far-fetched, one sexy idea is that the LHC may find extra dimensions of space/time. If so, the discovery could open the door to technologies that allow people to travel faster than the speed of light.

In a sense, Parker explained, scientists may discover an ability to move chunks of space-time from one place to another through those extra dimensions, effectively bypassing the known laws of physics.

"If you went to the 23rd century and there were people flying around faster than the speed of light, you would say, What is it you found out that enabled you to do this?" Parker said.

"And the answer might be, It all started when we discovered there were these extra dimensions."

Krauss, of Arizona State University, said that even without such advances, curiosity-driven research is fundamental to maintaining our current standard of living for generations into the future.

"It will help create innovation and enhance the economic future of our children in ways that we don't know," he said, adding that the chance to work with machines such as the LHC often attracts students to the sciences.

Krauss added that the big science questions being probed with the LHC are also personally relevant and practical for all members of society.

He explained that just as people are made of stardust, the origins of those particles in stardust stretch back to the beginning of the universe.

"If it all works out, you'll get a better understanding of what you're doing here," he said. "And, to me, that is the greatest benefit of science."

Linda Hall Library

Linda Hall Library
Kansas City, Missouri

The previous post was about Huntington Library and I feel obligated to also mention Linda Hall Library which is one of the world's leading collections of science, engineering, and technology repositories. Its collection [over a million volumes] dates from the fifteenth century to the present and includes first editions by Galileo, Newton, and Darwin.

I have used this library for 45 years and must say that in the Fall the grounds are spectacular.


From Wikipedia:


Linda Hall Library is a privately endowed library of science, engineering and technology located in Kansas City, Missouri.


Established in 1946 through the philanthropy of Linda and Herbert Hall (1858-1941), of the Hall-Baker Grain Co., the library has achieved global recognition and stature. The library is open to the public with individual researchers, academic institutions and companies from Kansas City and around the world using the library’s extensive research-level collection. Though not affiliated with its neighbor, the University of Missouri-Kansas City, many students and faculty from UMKC and other local colleges and universities utilize the library each day.


The library's collection includes academic journals, academic conference proceedings, reference works, publications by the government, and technical reports, industrial standards, engineering society conference papers, U.S. patents, and monographs. The library's distinguished History of Science Collection contains first editions of many landmarks of science and technology. Some of the oldest books in the collection date back to the fifteenth century.


The 14 acres surrounding the library are home to over 450 trees representing 58 genera and 165 species. The arboretum and gardens are further embellished by beds of viburnum, tree peonies and Missouri native woodland plants.

"Put a Little Science in Your Life"...please

Brian Greene

Up front I am no supporter of "string theory" or "far end" theoretical physics, but Op-Ed Contributor Brian Greene wrote this good article for the Sunday edition of The New York Times.

"Put a Little Science in Your Life"

by

Brian Greene

June 1st, 2008

The New York Times

A couple of years ago I received a letter from an American soldier in Iraq. The letter began by saying that, as we've all become painfully aware, serving on the front lines is physically exhausting and emotionally debilitating. But the reason for his writing was to tell me that in that hostile and lonely environment, a book I'd written had become a kind of lifeline. As the book is about science — one that traces physicists’ search for nature’s deepest laws — the soldier’s letter might strike you as, well, odd.

But it's not. Rather, it speaks to the powerful role science can play in giving life context and meaning. At the same time, the soldier’s letter emphasized something I’ve increasingly come to believe: our educational system fails to teach science in a way that allows students to integrate it into their lives.

Allow me a moment to explain.

When we consider the ubiquity of cellphones, iPods, personal computers and the Internet, it's easy to see how science (and the technology to which it leads) is woven into the fabric of our day-to-day activities. When we benefit from CT scanners, M.R.I. devices, pacemakers and arterial stents, we can immediately appreciate how science affects the quality of our lives. When we assess the state of the world, and identify looming challenges like climate change, global pandemics, security threats and diminishing resources, we don’t hesitate in turning to science to gauge the problems and find solutions.

And when we look at the wealth of opportunities hovering on the horizon — stem cells, genomic sequencing, personalized medicine, longevity research, nanoscience, brain-machine interface, quantum computers, space technology — we realize how crucial it is to cultivate a general public that can engage with scientific issues; there's simply no other way that as a society we will be prepared to make informed decisions on a range of issues that will shape the future.

These are the standard — and enormously important — reasons many would give in explaining why science matters.

But here's the thing. The reason science really matters runs deeper still. Science is a way of life. Science is a perspective. Science is the process that takes us from confusion to understanding in a manner that's precise, predictive and reliable — a transformation, for those lucky enough to experience it, that is empowering and emotional. To be able to think through and grasp explanations — for everything from why the sky is blue to how life formed on earth — not because they are declared dogma but rather because they reveal patterns confirmed by experiment and observation, is one of the most precious of human experiences.

As a practicing scientist, I know this from my own work and study. But I also know that you don't have to be a scientist for science to be transformative. I’ve seen children’s eyes light up as I’ve told them about black holes and the Big Bang. I've spoken with high school dropouts who’ve stumbled on popular science books about the human genome project, and then returned to school with newfound purpose. And in that letter from Iraq, the soldier told me how learning about relativity and quantum physics in the dusty and dangerous environs of greater Baghdad kept him going because it revealed a deeper reality of which we're all a part.

It’s striking that science is still widely viewed as merely a subject one studies in the classroom or an isolated body of largely esoteric knowledge that sometimes shows up in the “real” world in the form of technological or medical advances. In reality, science is a language of hope and inspiration, providing discoveries that fire the imagination and instill a sense of connection to our lives and our world.

If science isn't your strong suit — and for many it's not — this side of science is something you may have rarely if ever experienced. I’ve spoken with so many people over the years whose encounters with science in school left them thinking of it as cold, distant and intimidating. They happily use the innovations that science makes possible, but feel that the science itself is just not relevant to their lives. What a shame.

Like a life without music, art or literature, a life without science is bereft of something that gives experience a rich and otherwise inaccessible dimension.

It's one thing to go outside on a crisp, clear night and marvel at a sky full of stars. It's another to marvel not only at the spectacle but to recognize that those stars are the result of exceedingly ordered conditions 13.7 billion years ago at the moment of the Big Bang. It’s another still to understand how those stars act as nuclear furnaces that supply the universe with carbon, oxygen and nitrogen, the raw material of life as we know it.

And it's yet another level of experience to realize that those stars account for less than 4 percent of what's out there — the rest being of an unknown composition, so-called dark matter and energy, which researchers are now vigorously trying to divine.

As every parent knows, children begin life as uninhibited, unabashed explorers of the unknown. From the time we can walk and talk, we want to know what things are and how they work — we begin life as little scientists. But most of us quickly lose our intrinsic scientific passion. And it's a profound loss.

A great many studies have focused on this problem, identifying important opportunities for improving science education. Recommendations have ranged from increasing the level of training for science teachers to curriculum reforms.

But most of these studies (and their suggestions) avoid an overarching systemic issue: in teaching our students, we continually fail to activate rich opportunities for revealing the breathtaking vistas opened up by science, and instead focus on the need to gain competency with science's underlying technical details.

In fact, many students I've spoken to have little sense of the big questions those technical details collectively try to answer: Where did the universe come from? How did life originate? How does the brain give rise to consciousness? Like a music curriculum that requires its students to practice scales while rarely if ever inspiring them by playing the great masterpieces, this way of teaching science squanders the chance to make students sit up in their chairs and say, "Wow, that's science?"

In physics, just to give a sense of the raw material that’s available to be leveraged, the most revolutionary of advances have happened in the last 100 years — special relativity, general relativity, quantum mechanics — a symphony of discoveries that changed our conception of reality. More recently, the last 10 years have witnessed an upheaval in our understanding of the universe’s composition, yielding a wholly new prediction for what the cosmos will be like in the far future.

These are paradigm-shaking developments. But rare is the high school class, and rarer still is the middle school class, in which these breakthroughs are introduced. It's much the same story in classes for biology, chemistry and mathematics.

At the root of this pedagogical approach is a firm belief in the vertical nature of science: you must master A before moving on to B. When A happened a few hundred years ago, it's a long climb to the modern era. Certainly, when it comes to teaching the technicalities — solving this equation, balancing that reaction, grasping the discrete parts of the cell — the verticality of science is unassailable.

But science is so much more than its technical details. And with careful attention to presentation, cutting-edge insights and discoveries can be clearly and faithfully communicated to students independent of those details; in fact, those insights and discoveries are precisely the ones that can drive a young student to want to learn the details. We rob science education of life when we focus solely on results and seek to train students to solve problems and recite facts without a commensurate emphasis on transporting them out beyond the stars.

Science is the greatest of all adventure stories, one that’s been unfolding for thousands of years as we have sought to understand ourselves and our surroundings. Science needs to be taught to the young and communicated to the mature in a manner that captures this drama. We must embark on a cultural shift that places science in its rightful place alongside music, art and literature as an indispensable part of what makes life worth living.

It's the birthright of every child, it’s a necessity for every adult, to look out on the world, as the soldier in Iraq did, and see that the wonder of the cosmos transcends everything that divides us.

Bacon's bum rap?

Francis Bacon

Remember Friedrich Nietzsche's "Übermensch" meaning "overman"? And that Adolph Hitler took that word and construed it as "superman" and applied it to his Aryan race doctrine. Bum rap for Nietzsche. And Fancis Bacon? Similar situation? Lambast Bacon if you like for modern delimas of the environment and the relationship between science and technology but read: "...Works are of greater value as pledges of truth than as contributing to the comforts or life...." This is not unusual for people to remove statements from context and historical perspective and use them to champion some political cause or agenda.


"Is Bacon to blame for the evils of our polluted age?"

by

Nieves H. De Madariaga Mathews

When considering at what point we took a wrong turning, destructive to the earth and all that dwell upon it, those who are working for a new concept of science often invoke, as the villain of our disastrous piece, Francis Bacon, the 'father of experimental science', whose prophetic New Atlantis was published soon after his death in 1626. Bacon is reproached (along with Descartes) for spearheading a scientific revolution which promoted a mechanistic view of nature, and abdicated all responsibility for the results of its discoveries. Some have seen in a 'Messianic' Bacon the very model of the biotechnology at work today in the global markets - a 'cult camouflaged as science', 'a mindset that views science as a way of bringing man closer to God', and claims to improve our lives while actually degrading them.

In the film Mindwalk, based on the ideas of Fritjof Capra in The Turning Point (1982), Liv Ullman, as 'the physicist', indignantly decries our modern science, of which Francis Bacon is made the epitome. According to Bacon, the physicist declares, 'nature had to be hounded and made a slave to the new mechanicized devices; science had to torture nature's secrets out of her'.

And 'hasn't modern science', she concludes, 'done exactly what Francis Bacon preached - hasn't it tortured our planet?'

Did Bacon really preach these things? Many have believed he did, since, half-way through our century, two illustrious thinkers at the opposite extremes of the political scale concurred in laying at his door not only our polluted air, sea and soil, but the polluted lives of our alienated consumer society. In 1942 Herbert Marcuse, the patron saint of a generation of leftist extremists, described Bacon as the 'evil animus' of modern science, while Martin Heidegger, who was still celebrating in 1953 what he called 'the inner truth and greatness of Nazism', denounced in Bacon the symbol of a nefarious identification of science with technology. During those same decades Bacon's reputation as a scientist was also at its lowest ebb. At the hands of Karl Popper and others, the 'Great Secretary of Nature' had been demoted to sham thinker - a mere fact-collecting inductionist - and altogether excluded from the present scientific scene. Struck by the paradox, an eminent Baconian scholar, Paolo Rossi, pointed out that those who exalted science allowed Bacon no part in it, while those who looked on it as thoroughly evil, saw him as 'its very essence'.

When we turn to what Bacon actually said, however, these various dismissals prove groundless. Absorbed in their respective ideologies, their authors had failed to read Bacon in the original - and to read him in context - thus making a gross travesty of his model of science, and reducing his philosophy to a handful of slogans. This was the conclusion of various Baconian scholars who, in the 1980s, closely studied the meaning of his texts, reconstructing the situation in which he worked. Bacon's induction, based on the generation of laws from observation and experiment, by means of an intuitive 'analogical leap' from the observed to the unobservable, was shown to be a highly original contribution to philosophical thought, and he was rehabilitated as a founder of the new science, alongside Galileo and Descartes. His apparently one-sided exaltation of technology was similarly shown to have sprung from a misinterpretation - where not an actual misreading - of his words, in particular from the neglect of his basic tenet, that 'works are of greater value as pledges of truth than as contributing to the comforts or life'. We owe these misunderstandings in part to the tendency of some commentators to project the experience of a later time onto past ages (thus making Bacon, among others, a nineteenth century utilitarian, a positivist and even a Marxist). But we have also to understand why Bacon alone among English Renaissance thinkers, has been singled out in our time for consistent vilification. This anomaly has a good deal to do with the distorted image or his life which most of us have been brought up on, ever since, in 1837, the historian Macaulay published his brilliant but thoroughly untrustworthy essay, depicting a contemptible Bacon, soon to be loaded by subsequent biographers with every conceivable vice. This negative image of the man, which could not but influence that of the thinker, is still present in many people's minds, and it has made them only too ready to see him as a scapegoat for the harmful effects of the science he had heralded with so much acclaim. Bearing these points in mind we can now look at the principal complaints made of Bacon by the friends of Gaia.

Bacon's scientific revolution launched a mechanistic view of nature, in which living organisms are seen - and treated - as machines. The partition of the universe into live human mind and passive, mechanical nature was Descartes's gift to modern science, not that of Bacon, who stopped well short of 'the pitfall of classical mechanization', as it has been called.

Already in the eighteenth century the Italian philosopher, Vico, had congratulated his predecessor on having wisely avoided 'the rocks of mechanistic thought', while a contemporary recalled that, as a youth, he was given the works of Bacon to read so that he could be on his guard against 'the aberrations of Descartes'. For Coleridge 'the impulse towards a true natural philosophy, based on legitimate experience', had been betrayed by Descartes's science of mechanics. Like Shelley, Coleridge regarded Bacon as the man 'by whom Science was married to Poetry', while early in our century Alfred North Whitehead appreciated Bacon above all as a Renaissance vitalist.

And so we will find him. In his own Theory of Heaven he categorically denied the void he had earlier envisaged, and conjured up instead a starry heaven of 'fluctuating waves and reciprocations', an earth on which 'all objects emit rays'. He conceived the dynamic processes of nature - organic and inorganic - as a constant flow and ebb of 'vital spirits', struggling against the 'spirits' of inanimate matter to preserve youth and beauty, and to develop higher organic forms. It was by the synthesis of this universe in perpetual fluctuation with the quantitative aspects of his new science - a unique feat, as has been noted - that he sought to interpret all natural phenomena, 'from planet to planet, from spirit to star'. Indeed, with hisvital spirits, 'impressed by God upon the primary particles of matter', it looks as if Bacon had by-passed Newton's clockwork universe to rejoin the quantum scientist, Heisenberg, just as he had by-passed Aristotle to rejoin the pre-Socratic Heraclitus - that 'tracker-down of truth', as Bacon called him - whose complementary opposites he liked to recall, and with whose fire, 'both matter and moving force', Heisenberg identified his own 'particles of energy'. Anyone inclined to attribute a cold, mechanistic view of nature to Bacon should read his notes for a History of Generations and Pretergenerations, with its cascades or 'perturbations', 'vivifications' and 'gestations', its limitless 'potentialities', all leading to an order based on the 'generative and vivifying power in things' - a power which bears within it, 'like a second chaos', that air 'in which the seeds of so many things act, wander, endeavour and experiment'.

Bacon advocated 'the torture or nature'. 'The art of enquiry into nature itself, and or putting it on the rack', was never Bacon's, and these words, so often quoted against him, will not be found in any of his works. As recalled by Peter Pesic (from whose thorough studies of this subject, in Isis 1999 and elsewhere, I have taken most of the material for this section), they were written in 1696, by his great admirer, Leibniz, in praise or 'the art of experimentation which Lord Bacon began so ably'. Influenced, perhaps, by the fact that torture was still used in his day as a touchstone of certainty, Leibniz failed to distinguish, as Bacon emphatically did, between the concept or racking, or torture - terms which Bacon invariably connected with a brutal abuse - and that of 'the trials and vexation of art', indicating the agitation or provocation of nature in the course of an experiment aimed at verifying the evidence of the senses. Bacon depicted this 'vexing' or 'crossing' of nature with vivid images related to discovery or pursuit - never to torture. Many of them - such as 'espials', examination, trial, interrogation, deciphering - are taken from legal practice. Others are grouped around his concept of 'the Hunt or Pan, or Learned Experience' - a hunt 'in the woods or experience' for nature's laws - all of nature being 'nothing else than a hunt', while man himself 'hunts after his works'. If you 'follow and as it were, hound nature in her wanderings, you can drive her afterwards to the same place again': this is Bacon's description of controlled experiments aimed at making results replicable.

Turning to mythology, he described experimentation as a wrestling-match with that indestructible 'thrice-great prophet, Proteus, or Matter' - a matter permeated with spirit - who has to be gently but firmly held in place with the 'handcuffs' of mechanical aids, as he wriggles from one shape to another - or disappears for a time, as a gas; until, having rung all his changes, he finally discloses some of nature's secrets, thus assisting her to 'achieve her ends'. The experimenter is also tested in this process (being much in need of purification, since the mind of man is ever prone 'to distort the nature of things by mingling his own nature with it'). In the end, however, his part is a small one, for, Bacon insisted, 'all that man can do is to put together and put asunder natural bodies. The rest is done by nature within.' On the role played by man in vexing nature, within these limits, Bacon is quite clear. He gives examples from the age-old crafts - baking, brewing, pruning - by which nature is 'forced out of her natural state, and squeezed and moulded', and he cites experiments such as confining the spirits of wine in a sealed vessel, or making a rainbow in a spray of water.

We are far from the 'racking of nature' imagined by Leibniz. None the less, a few others were to follow him in confusing Bacon's charged images, and more recently various feminist writers - including Carolyn Merchant (1980), from whom, alas, Capra took his notion of Bacon's views - have contributed their own brand of confusion. Bacon is now denounced for launching 'a science infused with sexual and misogynistic metaphors' - in particular with images of rape and torture - aimed at encouraging middle-class male entrepreneurs 'to exploit nature, as a female to be tortured through mechanical inventions'. As Alan Soble has demonstrated (Oxford, 1998), none of the passages adduced by these writers remotely supports their claims. By omitting key words and sentences, and introducing metaphors of rape and of 'the torture chamber' where there are none, they completely transform his meaning. Thus Bacon's remark that 'a useful light' might be gained by the scientist from an inquiry into the arts of witchcraft, to Merchant 'strongly suggests the interrogations of the witch trials and the rnechanical devices used to torture witches' - and in Mindwalk he will be made out presiding over the witch trials of King James, though these were held in Scotland, many years before Bacon became Attorney General. Merchant saw caverns like that of the Sybil as 'sexual holes', and, she complained, Bacon 'frequently described matter in female imagery, as a "a common harlot"'. In fact he referred (twice) to an 'untenable opinion' of Plato's 'that matter is like a common harlot, always seeking after new forms'.

Nature cannot literally be tortured, but some of her creatures can, and often are today, in our service. At a time when vagabonds were regularly flogged, thieves hanged alive in chains, and felons gradually crushed to death under rocks, people were not much preoccupied with the suffering of animals. Descartes defended vivisection, and compared animals to creaking machines. Even Spinoza, half a century later, declamed in his Ethica that we could treat them 'in any way which best suits us'. Bacon was in two minds.

He believed that vivisection had rightly been condemned, but, in exceptional cases 'of great usefulness', it could have been a mistake to 'relinquish it altogether'. We may doubt that he ever came across such a case, for this 'tender-hearted' judge, as he was known to his contemporaries, who looked on offenders 'with the eye of compassion' - and who searched for ways of mitigating pain - repudiated torture, not only for its cruelty, but because he believed it was more liable to evoke 'strange fallacies' than to discover the truth. When 'vexing' even inorganic matter (which to him was alive) Bacon compared the care to be taken in regulating and varying the heat used in experiments to the gentle action of the womb. As for living tissue, eggs might be studied, but cutting out the foetus from the womb (as advocated by his contemporary William Harvey, who discovered the circulation of the blood) 'would be too inhuman'.

The womb is very present in Bacon's writings. He saw his own thought 'rooted in the lap and womb' of a nature more subtle 'many times over' than the mind of man, while the Scholastics 'touched nature only with the tips of their fingers, without mingling themselves into her being'. Had they 'remained attached to the womb of nature and continued to draw nourishment from her', he said, there would be no need for a new science. Far from preaching the rape of nature, the closer union Bacon sought with her was as the bride in 'a chaste and lawful marriage', from which 'many helps to man' might spring. (And should anyone object to the patriarchal view or her as a 'fruitful spouse', let us recall that nature appears as the dominant partner in another patriarchal image, with the arts subject to her 'as the wife is subject to the husband'). Bacon obviously preferred a 'happy match' to a grappling, however gentle. It is only men 'too intent upon their ends', he said, who 'rather struggle with Nature than woo her embraces with due observance and attention'.

Bacon offered mankind the boundless expansion of human power which has given science its daemonic and Faustian character. The power Bacon offered was never boundless. 'All knowledge is to be limited by religion', he said, 'and referred to use and action'. And keen as he was for man to 'open and dilate the powers of his understanding' and reach out to the spacious new worlds of discovery that lay beyond the pillars of Hercules, he never once lost sight of those essential restraints. The arrogant claim of unlimited power for man is precisely what he most strongly deprecated in the magicians of his day -those self-seeking and vainglorious 'braggarts', as he called them, who looked on themselves as gods, and in their 'blind greed' attempted 'to domineer over nature', merely to boost their own personal influence. It was not long since Marlowe's Dr Faustus, 'lord and commander or the elements', had boasted on the stage that his dominion 'stretched as far as doth the mind of man'. Bacon too, in The Advancement or Learning (1623), sought 'to extend the bounds of human empire' - but read on: 'as far as God Almighty in his goodness may permit.' (This limiting condition does not appear in the New Atlantis, where the sentence ends 'to the effecting of all things possible'. But the words are spoken there in the same religious context, 'for the love of God and man'.

What exactly do these religious limits to knowledge imply? While in sympathy with 'the heathen' (the fathers of whose church, he said, were the poets), Bacon lived his spirituality within the newly reformed Church of his time, as a practising Christian - witness his inspired religious writings, and his evident interest in 'the true temper of a man who has religion deeply seated in his heart'. He conceived his New Instauration as the fulfilment of a Biblical prophecy and a rediscovery of 'the seal of God on things'. Which did not mean that he could ever see in the practice of a technology 'a first step to becoming one with God' - as proclaimed of child-cloning by one of its famous promoters. On the contrary, Bacon repeatedly warned his readers against the 'unwholesome' mixture of things human and divine, and admonished them never to 'presume by the contemplation of nature to attain to the mysteries of God'. The meaning of that crucial condition, 'as far as the Almighty may permit', is simple. Bacon solemnly disavowed both 'power and knowledge such as is not dedicated to goodness or love'. The words are used with precision. 'Goodness' means the search of truth for its own sake - since 'the very beholding of light is itself a more excellent thing than all the uses of it'. 'Love', or 'goodness applied', means doing everything possible to relieve 'the immeasurable helplessness of the human race'.

This aim was the leitmotiv of Bacon's life, and his whole new concept of science was geared to it. He had seen the effects of hunger at first hand as a young legal counsel, when examining a band of rebel yeomen. Shocked by what he found, he had set out to study their condition, and had defended, in Parliament after Parliament - with a heat that surprised fellow Members - a Statute for the Relief of the Poor that was to last for centuries, and his two bills against the enclosure of common lands - which, he rightly insisted, 'destroyed the bread of the poor'. Bacon believed that poverty could best be eliminated by achieving abundance for all, and it was to remedy 'the pinched and narrow state of human fortunes' that he wanted to multiply the discoveries of science, made so far by accident, like that of silk, glass or the magnet. This claim, now used by some multinationals to justify their depredations, was a new one at that time, although he had inherited his strong sense of the service owed to mankind from an ancient Platonic and Christian tradition known as the vita activa, of which his friend, Sir Philip Sidney, was the living example. Bacon was however the first scientific thinker to have appropriated the vita activa to science, and made 'the weal of man' his goal.

It is in this light, and recalling his precept that 'the true ends of knowledge' are neither profit, fame nor power, that we should interpret his concept of dominion over nature - a dominion evoking the benevolent authority of the first King of Atlantis, with his 'large heart, inscrutable for good'. For Bacon, power meant 'the power to do good'. There is no place in the New Atlantis for a world dominion, which he described as 'the evil dream of a prosperous brigand'. In the heyday of colonization he stressed that 'people are not to be planted' so as to displace others, and he lamented the miserable fate of 'the poor Indies, brought from freedom to be slaves'. Neither did he look on nature as man's slave. The only case in which he appears to couple slavery with nature - when offering an imaginary pupil 'to bind nature to your service and make her your slave' - has been found to be a mistranslation of the Latin original for 'slave', 'mancipaturus', which actually means 'to be assigned to an office'. It implies a bond - in Bacon's case a mutual one - but without the indignity of slavery. Himself, as he believed, 'born for the service of mankind', Bacon took every opportunity to emphasize that man is but the servant of that nature which he was now joyfully placing at the service of his 'dear, dear son'; that beyond following and observing her order, he 'knows nothing and can do nothing'; and above all that 'the least part of knowledge' is passed to him 'by a Charter from God', and 'must be subject to that use for which God hath granted it'. Failing which 'all manner of knowledge becometh malign and serpentine.'

In the New Atlantis Bacon set up a model for the manipulation of nature which, carried to extremes, has led to the widespread genetic modification of plants by our multinational corporations. Bacon extended his inexhaustible capacity for wonder to 'the border regions of knowledge', as he put it. There was nothing he did not propose to study, from the transmutation of metals, and 'those minute particles that do so great effect ', to a drink he had heard of 'called coffa, as black as soot and of a sharp scent, which comforteth the brain and heart'. He wished an inquiry to be carried out 'with all sobriety and severity', into 'the transmission of spirits at a distance', precognition, hypnosis and telepathic dreams. And he was interested in every aspect of plant life, from their 'enlarging and dwarfing', and 'transplanting one species into another', to the effects of 'the force of imagination' on 'their sudden fading or lively coming up', their closing and opening, their 'bending one way or another'.

But, whatever our opinion of his programme, we cannot reproach Bacon for holding the man-centred - and in his case still earth-centred - view of the universe, which has been an essential part of our Western tradition since Genesis. Or for advocating a manipulation of nature that has been with us ever since Cain ploughed the first field and a Persian gardener bred the first rose. That our species should thrive at the expense of the rest of creation, appears to us now increasingly 'malign and serpentine'. Many of us are more in sympathy - at least as a counsel of perfection - with Eastern attitudes that deprecate stepping on an insect, or those of native Americans, when they ask a plant's permission to harvest it. But where exactly does each of us stand? Do we accept the human kidney transplant but not the heart of a pig? Can we take as a gift from Bacon's prescience hearing aids and spectacles, microscopes and air-conditioners - submarines even, but not those dangerously polluting aeroplanes? Do we accept 'the multiplication of light at a distance', and Bacon's binary scale, on which our computers are based, but not the medical panaceas - or at least not the cosmetics - we owe to the suffering of mice and dogs? Some of us now think we should not destroy life 'without sufficient reason'. But how much is sufficient? Ought we to eat miserable factory-farmed animals, when a less sentient vegetable could feed us? Bacon's position was clear. He would 'try all things and hold that which is good.' We are trying all things, but we no longer know what is good. And we stop at nothing. In each case it is possible to identifiy the point at which we disregarded the limits Bacon laid down, and, failing to obey nature, brought - and are still bringing - upon ourselves every kind of disaster. ('Force maketh Nature more violent in the return.')

We will find Bacon in radical disagreement with the promoters of present day biotechnology on at least four fundamental counts. The first relates to their respective priorities. For Bacon, profit was excluded. Research was a matter of public funds - a task, he said, 'for Kings and Popes', and he stringently admonished scientists who 'turn aside after profit or commodity' : they do so, he warned, 'to the infinite loss of mankind'. There can be no comparison between a philosopher whose 'only earthly wish', from youth to old age, was to promote inventions that could relieve the poverty of man, and a corporation professing to 'do the right thing (namely, to feed mankind) while doing business', and publicizing this worthy aim out of the huge profits they had made with ventures such as Agent Orange and the defoliation of Vietnam; or planning the sinister Terminator Seed 'to protect their investments'. The second difference is one of scale. The ever moderate, middle-of-the-way Bacon, who noted that 'the personal fruition of man cannot attain to feel great riches', knew that more is not better. ('It is the empty things that are vast, things solid are most contracted, and lie in little room.') Bacon could not have conceived the escalating size, the global greed of corporations coolly planning to take over a large portion of the earth's water resources or feverishly decoding some three billion DNA sequences, in a bid to patent the entire human genome. The third radical difference between corporation practice and the thinker who would not reap the green corn, and who reminded us that it is not the tempest but 'the soaking rain that relieves the ground', is one of timeliness. Bacon would have deplored, as the worst 'levity and rashness in new experiments', the immoderate haste with which giant multinationals are now combing the virgin forests for plants that have yielded their healing properties over the millennia, in a headlong rush to extract, code, genetically modify and patent substances which would require generations of testing before they can be fed to adults - rnuch less to babies. The fourth, and perhaps most striking difference, is the contrast between the corporations' stealthy moves to impose their untested wares on us, as a part of their silent progress towards world supremacy - with Bacon's declared goals of open communication and exchange of knowledge, placed at the service of mankind.

Bacon promoted a science in which the experimenter abdicates all responsibility for the results of his discoveries. In fact Bacon was the only thinker of his day to unite scientific knowledge with ethical ideals, as he was the first to evolve a concept of fraternity in 'learning and illumination' among scientists of all countries, 'joining forces for the common good'. Bacon presents his new scientist - neither 'Schoolman' nor magus, but a 'pioner' (or digger) in the mine of truth - with 'tears of tenderness' for his fellow beings in his eyes. And it is because he envisaged a succession of such scientists, handing down the torch of a continuous tradition, at his symbolic 'Promethean Games', that Loren Eiseley described Bacon as 'the first great statesman of science'. But as a statesman Bacon was also aware of the dangers of scientific knowledge, and, on setting forth his plan of work for the Great Instauration, he confessedto 'inward hesitations and scruples'. The new learning, he feared, 'might open a fountain', and who could tell where its waters would fall? Alone among the forerunners of modern science Bacon foresaw the possibility of that 'Rape of Minerva (wise nature), by Vulcan (the mechanical arts)', which we have since perpetrated. His myth of 'Daedalus, or the Mechanic' - famous for his 'pernicious genius', 'unlawful inventions' and 'depraved applications' - sounds a dire warning against the 'imperfect births and lame works' which 'chemical productions and mechanical subtleties' could lead to, if mechanical art should attempt 'to force Nature to its will. And well we know how far in cruelty and destructiveness they exceed the Minotaur himself.'

Bacon hoped, as many have after him, that the mechanical arts might 'serve as well for the cure as for the hurt'. And since people are not to be trusted with dangerous discoveries, the brotherhood of Salomon took an oath of secrecy for 'the concealing of all inventions they thought fit to keep secret', even, if necessary, from the state - a solution not open to our democracies, although some scientists have resorted to it, and one great poet has appealed for it to be practised in our time. (In any case the salutary independence of scientists from Bacon's Utopian state compares favourably with the tacit understanding between powerful corporations and some of our governments.) The only reliable safeguard, however, in Bacon's view, was the age-old remedy of prayer, and in New Atlantis daily services were held 'of laud and thanks to God for his marvellous works', and of prayers (similar to those Bacon affixed to his own works) 'imploring God's aid and blessing for the illuminatiori of our labours, and the turning of them to good and holy uses'. For Bacon the efficacy of prayer was not in doubt. He saw the orations of the monastic orders as 'true works that cast their beams upon society for the benefit of man'. In our less believing age we may look on the prayers offered daily at Salomon's House as a declaration of intent, and a decision to maintain that intent by concentrating the mind upon it.

It is for the firmness of his own purpose and the stress he laid on turning our labours to good uses that I think ecologists can look on Bacon as an ally in the struggle ahead. The needs of humanity are changing, but never has it been more imperative for us to 'join forces for the common good' - that of our whole planet, this time. Bacon's was a cyclical view of history, in which 'the sciences have their ebbs and flows'. Four centuries ago he proclaimed a science that was to go on 'fructifying and begetting', as long as there was room for its wastes. But now that the tide has begun to turn, might not the forward-looking Bacon, had he lived today, be urging us to redirect our inborn thirst for knowledge away from the dead-ends of uncontrolled genetic engineering and the nuclear nightmare? Towards - new variants of earth-healing culture, perhaps? Undiscovered forms of renewable energy, a 'revivifying' concept of growth, or some other form of resurgence we haven't yet thought of?

Be that as it may, he appears to be in unison with the ecological vision in one respect. There is a remarkable affinity between Bacon's dynamic concept of the origins of life, and the cosmologies now emerging in centres like Schumacher College at Dartington, and the Santa Fe Institute of New Mexico - an affinity perceptible even in the vocabulary of these seekers. The 'fluctuating patterns' now found 'running deep in nature' (as cited by Brian Goodwin, in How the Leopard Changed his Spots, 1994), bring to mind those 'fluctuating reciprocations' noticed above in Bacon, the 'resemblances and conjugations' which, he believed, 'reveal the unity of nature' and 'the fabric of the universe'. And when we read today of 'the dynamic fluidity' with which elements 'move from chaos to order and back again', interacting rather than competing, in 'a creative play of forms', or 'a sacred dance', we are very close to that world which, in Bacon, 'enjoys itself and in itself all things that are', while 'the souls of the living leap about and dance with infinite variety'; a world in which 'Pan, or Nature' is ever inclined to 'fall back into ancient chaos' - but that Cupid foils him in the contest; in which God himself 'delights in hiding his works', so as to give man the pleasure of finding them.

We must not forget that if Bacon took the dominion of Adam over his fellow-creatures for granted, he himself extended his 'feeling of communion with men also to beasts', had thoughts of 'nourishing and comforting the trees', and dearly loved birds. He believed that nature was 'corrupted by too much cultivation' - after all the first scientists were 'the brute beasts, quadrupeds, fishes and serpents'. And when it rained, we are told, he would go out in his open coach 'to receive the Nitre in the air and the Universal Spirit of the World'. Let us hear him in his History of the Winds, a late work, urging us to 'make a stay with nature' and 'meditate upon her':

'Wherefore if there be any humility towards the Creator; if there be any praise and reverence towards his works; if there be any charity towards men and zeal to lessen human want and sufferings; if there be any love of truth in natural things ... men are to be entreated again and again ... that they should humbly and with reverence draw near to the book of Creation, and becoming again as little children, deign to take its alphabet into their hands.'
