Olin Engineering Education Experiment

Excellent article: The Olin Experiment by Erico Guizzo:

Founded with more than US $460 million from the F.W. Olin Foundation, the school, which will graduate its first class at the end of this month, was conceived as perhaps the most ambitious experiment in engineering education in the past several decades. Olin’s aim is to flip over the traditional “theory first, practice later” model and make students plunge into hands-on engineering projects starting on day one. Instead of theory-heavy lectures, segregated disciplines, and individual efforts, Olin champions design exercises, interdisciplinary studies, and teamwork.

And if the curriculum is innovative, the school itself is hardly a traditional place: it doesn’t have separate academic departments, professors don’t get tenured, and students don’t pay tuition – every one of them gets a $130 000 scholarship for the four years of study.

Building a Better Engineer by David Wessel:

To a visitor, the school resembles any other small college. What’s different about it is its almost messianic mission: to change the way engineers are educated in the U.S. so that they can help the U.S. compete in a global economy with lots of smart, ambitious engineers in China, India and elsewhere. “If they become another good engineering school, they will have failed,” says Woodie Flowers, an MIT professor advising Olin. “The issue is to do it differently enough and to do it in way that will be exportable” to other colleges.

We share more thoughts on Olin’s efforts to improve engineering education on our other blog.

Seeing Machine from MIT

MIT poet develops ‘seeing machine’ by Elizabeth A. Thomson

The work is led by Elizabeth Goldring, a senior fellow at MIT’s Center for Advanced Visual Studies. She developed the machine over the last 10 years, in collaboration with more than 30 MIT students and some of her personal eye doctors. The new device costs about $4,000, low compared to the $100,000 price tag of its inspiration, a machine Goldring discovered through her eye doctor.
…
The pilot clinical trial of the seeing machine involved visually impaired people recruited from the Beetham Eye Institute. All participants had a visual acuity of 20/70 or less in the better-seeing eye. A person with 20/70 vision can see nothing smaller than the third line from the top of most eye charts. Most participants, however, had vision that was considered legally blind, meaning they could see nothing smaller than the “big E” on a standard eye chart.
…
Goldring and colleagues are now working toward a large-scale clinical trial of a color seeing machine (the device tested in the pilot trial was black and white).

Donald Knuth – Computer Scientist

Love at First Byte by Kara Platoni:

In the early ’60s, publisher Addison-Wesley invited Knuth to write a book on compiler design. Knuth eagerly drafted 3,000 pages by hand before someone at the publishing house informed him that would make an impossibly long book. The project was reconceived as the seven-volume The Art of Computer Programming. Although Knuth has written other books in the interim, this would become his life’s work. The first three volumes were published in 1968, 1969 and 1973. Volume 4 has been in the works nearly 30 years.

Its subject, combinatorial algorithms, or computational procedures that encompass vast numbers of possibilities, hardly existed when Knuth began the series. Now the topic grows faster than anyone could reasonably chronicle it. “He says if everyone else stopped doing work he would catch up better,” deadpans Jill Knuth, his wife of nearly 45 years.

Art of Computer Programming, Volume 1: Fundamental Algorithms – Art of Computer Programming, Volume 2: Seminumerical Algorithms – Art of Computer Programming, Volume 3: Sorting and Searching

Usually a lone wolf, Knuth collaborated on his typography programs with some of the world’s best typographers and his students. He produced two software programs, the TeX typesetting system and the METAFONT alphabet design system, which he released to the public domain. The programs are used for the bulk of scientific publishing today. “He made everybody’s life so much better and made the scholarly work so much more beautiful,” Papadimitriou says. “He has exported a lot of good will for computer science.”

See photo:

He likes to hide jokes in the index, as in Volume 3, where “royalties, use of” leads you to a page with an illustration of an organ-pipe array, a little wink to the 16-rank organ that dominates his home. He plays four-hands music with Jill, who swears that the neighbors tend to complain that the music emanating from their house is in fact not loud enough.

Entirely New Antibiotic Developed

Potent antibiotic to target MRSA

A potent antibiotic which kills many bacteria, including MRSA, has been discovered. Scientists with Merck, isolated platensimycin from a sample of South African soil and have developed an antibiotic based on that discovery.

If the compound passes clinical trials it will become only the third entirely new antibiotic developed in the last four decades.

Details in the journal Nature reveal the antibiotic works in a completely different way to all others.

It acts to block enzymes involved in the synthesis of fatty acids, which bacteria need to construct cell membranes.

Methicillin-resistant Staphylococcus Aureus (MRSA) is a type of bacteria that is resistant to certain antibiotics, including: methicillin and other more common antibiotics such as oxacillin, penicillin and amoxicillin. Staph infections, including MRSA, occur most frequently among persons in hospitals and healthcare facilities who have weakened immune systems. More information on MRSA is available from the United States Center for Disease Control and Prevention.

Scientific Misinformation

Lactic Acid Is Not Muscles’ Foe, It’s Fuel by Gina Kolata:

But that, it turns out, is all wrong. Lactic acid is actually a fuel, not a caustic waste product. Muscles make it deliberately, producing it from glucose, and they burn it to obtain energy.
..
“I had huge fights, I had terrible trouble getting my grants funded, I had my papers rejected,” Dr. Brooks recalled. But he soldiered on, conducting more elaborate studies with rats and, years later, moving on to humans. Every time, with every study, his results were consistent with his radical idea.

Eventually, other researchers confirmed the work. And gradually, the thinking among exercise physiologists began to change.

Nanoscale Fractal Molecule

Nanoscale Fractal Molecule

Scientists Create the First Synthetic Nanoscale Fractal Molecule by Andrea Gibson:

The molecule, developed by researchers at the University of Akron, Ohio University and Clemson University, eventually could lead to new types of photoelectric cells, molecular batteries and energy storage, according to the scientists, whose study was published online today by the journal Science.

A University of Akron research team led by Vice President for Research George Newkome used molecular self-assembly techniques to synthesize the molecule in the laboratory. The molecule, bound with ions of iron and ruthenium, forms a hexagonal gasket.

Ohio University physicists Saw-Wai Hla and Violeta Iancu, who specialize in imaging objects at the nanoscale, confirmed the creation of the man-made fractal. To capture the image, the physicists sprayed the molecules onto a piece of gold, chilled them to minus 449 degrees Fahrenheit to keep them stable, and then viewed them with a scanning tunneling microscope.
