Score One for Sports Science

Score one for science (link broken so removed)

Bray has analyzed memorable games over the past 50 years and applied research in physics, biology, computing and psychology to the beautiful game.

Using biomechanics to calculate the absolute reach of a goalkeeper diving to try to save a penalty, Bray has identified an area near the posts and in the top corners where the goalkeeper cannot reach as the “unsaveable zone.”

“If a player were to place the ball in those regions, which are 28-30 percent of the goal area, there is not a sniff that the goalkeeper can do to get across to them,” explained Bray, from the University of Bath in England.

America’s Technology Advantage Slipping

A Red Flag In The Brain Game.

The 30th Annual ACM-ICPC World Finals sponsored by IBM were held in San Antonio this April: view results.

Of the home teams, only Massachusetts Institute of Technology ranked among the 12 highest finishers. Most top spots were seized by teams from Eastern Europe and Asia. Until the late 1990s, U.S. teams dominated these contests. But the tide has turned. Last year not one was in the top dozen.

As an indicator this is a minor one. But it is one more indication that indeed the tide is turning. The results seem worse based on “The 83 teams who competed in the World Finals are made up of 22 North American teams, 3 teams from Africa/Middle East, 7 from Latin America, 22 from Europe and Russia, and 29 from the Asia/South Pacific region.” So the USA had close to 20% of the participants and only 1 of the top 38 teams (Canada had at least 4 in the top 38). The USA had 5 of the 17 teams tied for 39th place.

The poor showings should serve as a wake-up call for government, industry, and educators. The output of American computer science programs is plummeting, even while that of Eastern European and Asian schools is rising. China and India, the new global tech powerhouses, are fueled by 900,000 engineering graduates of all types each year, more than triple the number of U.S. grads. Computer science is a key subset of engineering. “If our talent base weakens, our lead in technology, business, and economics will fade faster than any of us can imagine,” warns Richard Florida, a professor at George Mason University and author of The Flight of the Creative Class.

Again results of two years of this programming challenge are hardly a significant indication. Still if there was any field that Americans felt they still felt they were dominant in it would likely be programing (maybe health care – what do you think?). Given that this seemed at least worth a post in our blog.

It is also interesting to note, this Business Week article uses the “China and India, the new global tech powerhouses, are fueled by 900,000 engineering graduates of all types each year, more than triple the number of U.S. grads.” stats even though this article specifically tracks a Duke team and Business Week published several articles on the Duke study, USA Under-counting Engineering Graduates, that refutes those numbers.

Invention Machine

John Koza Has Built an Invention Machine by Jonathon Keats:

Now 62 and an adjunct professor at Stanford University, Koza is the inventor of genetic programming, a revolutionary approach to artificial intelligence (AI) capable of solving complex engineering problems with virtually no human guidance. Koza’s 1,000 networked computers don’t just follow a preordained routine. They create, growing new and unexpected designs out of the most basic code. They are computers that innovate, that find solutions not only equal to but better than the best work of expert humans. His “invention machine,” as he likes to call it, has even earned a U.S. patent for developing a system to make factories more efficient, one of the first intellectual-property protections ever granted to a nonhuman designer.

Yet as impressive as these creations may be, none are half as significant as the machine’s method: Darwinian evolution, the process of natural selection. Over and over, bits of computer code are, essentially, procreating. And over the course of hundreds or thousands of generations, that code evolves into offspring so well-adapted for its designated job that it is demonstrably superior to anything we can imagine.

Great article from Popular Science magazine.

Mistake Driven Engineering

Book Cover graphic - Success Through Failure

Engineering a Safer, More Beautiful World, One Failure at a Time by Cornelia Dean:

Success masks failure. The more a thing operates successfully, the more confidence we have in it. So we dismiss little failures — like the repeated loss of a space shuttle’s insulating tiles launchings — as trivial annoyances rather than preludes to catastrophe.

Success through Failure: The Paradox of Design by Henry Petroski – read a sample chapter (from Princeton University Press):

Sometimes, as when a part breaks in two, the focal point for the improvement is obvious. Other times, such as when a complex system runs disappointingly slowly, the way to speed it up may be far from clear. In all cases, however, the beginnings of a solution lay in isolating the cause of the failure and in focusing on how to avoid, obviate, remove, or circumvent it. Inventors, engineers, designers, and common users take up such problems all the time.

Fighting Superbugs with Milk

Cocks has found that the mother’s milk contains a molecule that is 100 times more effective against Gram-negative bacteria such as E. coli than the most potent form of penicillin. The molecule, called AGG01, also kills four types of Gram-positive bacteria and one type of fungus. The work was presented at the US Biotechnology Industry Organization 2006 meeting in Chicago last week.

Center for Innovation in Engineering Education at Princeton

The Center for Innovation in Engineering Education at Princeton University was created in February 2005 with the purpose of setting a new standard for engineering education emphasizing interdisciplinary areas, societal context, and leadership.

“Our plan is to set a new standard for engineering education,” said H. Vincent Poor, the director of the center and Princeton’s George Van Ness Lothrop Professor in Engineering. “We want to inject more engineering into the liberal arts and inject more of the liberal arts into engineering.”

Presidential Awards for Excellence in Mathematics and Science Teaching

President George W. Bush has announced that 100 educators will receive the annual Presidential Awards for Excellence in Mathematics and Science Teaching for 2005. The award was established in 1983. This year, the White House recognizes the best of the Nation’s 7th – 12th grade mathematics and science teachers.

A national panel of distinguished scientists, mathematicians, and educators recommends teachers to receive the Presidential Awards which are administered by the National Science Foundation.

Awardees receive a $10,000 educational grant for their schools and a trip to Washington, D.C., to accept a certificate. The teachers will be in the Nation’s capital from May 1-6, 2006, to receive the award and participate in a variety of educational and celebratory events.

During the week the teachers will tour the White House and be honored in an awards ceremony hosted by Dr. John H. Marburger III, Science Advisor to the President and Director, White House Office of Science and Technology Policy. They will also meet with members of Congress and the Administration to discuss the latest issues in mathematics and science teaching.

For a complete listing of the 2005 awardees visit the Presidential Awardees for Excellence in Mathematics and Science Teaching web site.

Study on Minority Degrees in STEM fields

The American Council on Education has published a study: Increasing the Success of Minority Students in Science and Technology.

Key Findings:

  • In the 1995-96 academic year, 18.6 percent of African-American students and 22.7 percent of Hispanic students began college interested in majoring in STEM fields compared with 18 percent of white students and 26.4 percent of Asian-American students.
  • By the spring of 2001, 62.5 percent of African Americans and Hispanics majoring in STEM fields attained a bachelor’s degree compared with 94.8 percent of Asian Americans and 86.7 percent of whites.

Students who graduated in STEM fields (by spring 2001) were:

  • better prepared for postsecondary education because a larger percentage took a highly rigorous high school curriculum.
  • nearly all were younger than 19 when they entered college in 1995-96
  • more likely to have at least one parent with a bachelor’s degree or higher.
  • came from families with higher incomes.
  • more likely to work 15 hours or more a week.

What’s so Exciting About Engineering?

What’s so exciting about engineering? by Leigh M. Chowdhary:

“I thought it was really great,” says Hannah M., an 8th grader at Sacred Heart Middle School. “I liked the experiments.”

A crew of 150 girls age 10 to 14 from four Chicago area schools were scientists for a day. Some kids used static electricity from balloons to move sticks through a racecourse. Others watched videos of female inventors–who created things such as smear-proof lipstick and Kevlar (a substance used in bullet-proof vests).
