2007 Draper Prize to Berners-Lee

Timothy J. Berners-Lee will receive the prestigious Charles Stark Draper Prize for Engineering from the US National Academy of Engineering (NAE) for developing the World Wide Web.

Also, Yuan-Cheng “Bert” Fung will receive the Fritz J. and Dolores H. Russ Prize — a $500,000 biennial award (since 1999) recognizing engineering achievement that significantly improves the human condition — “for the characterization and modeling of human tissue mechanics and function leading to prevention and mitigation of trauma.”

Timothy J. Berners-Lee imaginatively combined ideas to create the World Wide Web, an extraordinary innovation that is rapidly transforming the way people store, access, and share information around the globe. Despite its short existence, the Web has contributed greatly to intellectual development and plays an important role in health care, environmental protection, commerce, banking, education, crime prevention, and the global dissemination of information.

MIT for Free

How to go to M.I.T. for free by Gregory M. Lamb:

By the end of this year, the contents of all 1,800 courses taught at one of the world’s most prestigious universities will be available online to anyone in the world, anywhere in the world. Learners won’t have to register for the classes, and everyone is accepted. The cost? It’s all free of charge.

The OpenCourseWare movement, begun at the Massachusetts Institute of Technology (MIT) in 2002 and now spread to some 120 other universities worldwide, aims to disperse knowledge far beyond the ivy-clad walls of elite campuses to anyone who has an Internet connection and a desire to learn.
…
MIT’s OCW website features even more glowing feedback from learners. “[B]ecause of money, many good students with great talent and [who are] diligent do not have the chance to learn the newest knowledge and understanding of the universe,” says Chen Zhiying, a student in the People’s Republic of China. “But now, due to the OCW, the knowledge will spread to more and more people, and it will benefit the whole [world of] human-beings.”

Sarah, aged 3, Learns About Soap

A Dialogue with Sarah, aged 3: in which it is shown that if your dad is a chemistry professor, asking “why” can be dangerous [the broken link was removed] by Stephen McNeil.

DAD: Why does the soap grab the dirt?
SARAH: Yes.
DAD: Because soap is a surfactant.
SARAH: Why?
DAD: Why is soap a surfactant?
SARAH: Yes.
DAD: That is an EXCELLENT question. Soap is a surfactant because it forms water-soluble micelles that trap the otherwise insoluble dirt and oil particles.

Great. I remember such discussions with Dad (Chemical Engineering professor). The only danger I saw was him getting tied of -why? (when I was older). And sometimes giving me answers the teacher didn’t like (a way of doing math problems that wasn’t the way my teacher was teaching).

Epidemic of Diagnoses

Edited version from our managment improvement blog.

What’s Making Us Sick Is an Epidemic of Diagnoses by Dr. Welch, Dr. Schwartz and Dr. Woloshin:

For most Americans, the biggest health threat is not avian flu, West Nile or mad cow disease. It’s our health-care system.

True, and probably the biggest economic threat too.

But it also leads to more diagnoses, a trend that has become an epidemic.
This epidemic is a threat to your health. It has two distinct sources. One is the medicalization of everyday life. Most of us experience physical or emotional sensations we don’t like, and in the past, this was considered a part of life. Increasingly, however, such sensations are considered symptoms of disease.

When I read:

But the real problem with the epidemic of diagnoses is that it leads to an epidemic of treatments. Not all treatments have important benefits, but almost all can have harms.

I just think: tampering!

Boiling Water in Space

Bizarre Boiling, NASA:

The next time you’re watching a pot of water boil, perhaps for coffee or a cup of soup, pause for a moment and consider: what would this look like in space? Would the turbulent bubbles rise or fall? And how big would they be? Would the liquid stay in the pan at all?

Until a few years ago, nobody knew. Indeed, physicists have trouble understanding the complex behavior of boiling fluids here on Earth. Perhaps boiling in space would prove even more baffling…. It’s an important question because boiling happens not only in coffee pots, but also in power plants and spacecraft cooling systems. Engineers need to know how boiling works.

I had trouble seeing what was happening in the first video. Try this video first.

Because a smaller volume of water is being heated, it comes to a boil much more quickly. As bubbles of vapor form, though, they don’t shoot to the surface — they coalesce into a giant bubble that wobbles around within the liquid.

Engineers Week Ideas

Ideas for engineers to use during engineering week, from the Engineering Education Service Center (on the USA engineering week):

Engineers week is a unique time that takes place every February during Presidents week. 40,000 engineers go into classrooms to promote the profession and give students a better understanding of engineering. This is our chance to show the world that engineering is an exciting career and that engineers really can do anything!

If you know of other similar activities in other countries please add a comment.

Personal Water Wheel Power

Personal Water Wheel

Scots inventor cracks centuries-old puzzle

Ian Gilmartin, 60, has invented a mini water wheel capable of supplying enough electricity to power a house – for free. The contraption is designed to be used in small rivers or streams – ideal for potentially thousands of homes across Britain. It is the first off-the-shelf water-wheel system that can generate a good supply of electricity from as little as an eight-inch water fall.
…
The water wheel produces one to two kilowatts of power and generates at least 24kw hours of sustainable green energy in a day – just under the average household’s daily consumption of about 28kw hours. It will cost some Â£2,000 to fully install – and pay for itself inside two years.
…
A “high head”, such as a traditional water wheel, is large, expensive and needs civil engineering. But with low heads of under 18 inches, no-one had invented a method of successfully recovering the energy generated – until now. A conventional water wheel allows the water to escape prematurely as the wheel rotates, but the Beck Mickle hydro generator contains the water for the full drop of the device, converting about 70 per cent of the energy into electricity.

Scientists Knock-out Prion Gene in Cows

Scientists Announce Mad Cow Breakthrough by Rick Weiss

Scientists said yesterday that they have used genetic engineering techniques to produce the first cattle that may be biologically incapable of getting mad cow disease. The animals, which lack a gene that is crucial to the disease’s progression, were not designed for use as food. They were created so that human pharmaceuticals can be made in their blood without the danger that those products might get contaminated with the infectious agent that causes mad cow.

That agent, a protein known as a prion (pronounced PREE-on), can cause a fatal human ailment, variant Creutzfeldt-Jakob disease, if it gets into the body. More generally, scientists said, the animals will facilitate studies of prions, which are among the strangest of all known infectious agents because they do not contain any genetic material.
…
Prions remain poorly understood, but experiments suggest that it takes just one bad one to ruin a brain. That’s because a badly folded prion in the brain can strong-arm normal, nearby prions, turning good prions bad.

Antibiotic resistance: How do antibiotics kill bacteria?

Many, if not most, antibiotics act by inhibiting the events necessary for bacterial growth. Some inhibit DNA replication, some, transcription, some antibiotics prevent bacteria from making proteins, some prevent the synthesis of cell walls, and so on. In general, antibiotics keep bacteria from building the parts that are needed for growth.
…
It seems funny to think that not growing can be a mechanism for survival. But if you’re a bacteria, and you can hang around long enough in an inactive, non-growing state, eventually your human host will stop taking antibiotics, they will disappear from your environment and you can go back to growing.
