Five Indian students win Intel awards:

Five Indian students are among the winners at the Intel International Science and Engineering Fair, the world’s largest pre-college science competition in which an Indian-American girl also received a $50,000 scholarship by taking top honours.

The students excelled among a record-setting, worldwide pool of 1,482 competitors from 47 countries, regions and territories, setting the bar for future scientific research in three disciplines.

Teen’s project places second at science fair

His engineering design for emergency shelters, now in the hands of the U.S. Patent and Trademark office, yesterday earned Toll, 17, a junior at Cedar Crest High School, a second-place award at an international science fair in Indianapolis.

  • Melissa Green, a graduate student in mechanical and aerospace engineering, who was awarded second place for “Isolated Hairpin,” a computer simulation of turbulent air flow
  • Qiangfei Xia, a graduate student in electrical engineering, who won third place for “Easter Bonnet,” a photograph taken with an electron scanning microscope of a tiny piece of metal melted by a laser onto a silicon chip.

Demystifying Technology for High School Students

Demystifying technology for high-schoolers by Greg Rienzi, Johns Hopkins University News:

The Engineering Innovation program, which Hopkins will initially offer at three JHU campuses and five California universities, will allow high school sophomores, juniors and seniors to enroll in the college-level course What is Engineering? taught by Johns Hopkins or other university-accredited faculty.

The initiative is based upon a successful program the Whiting School developed five years ago for students in Montgomery County. The program was expanded last year to include students in Baltimore City and Baltimore County.
…
The participants in the program will spend four weeks learning the basics of engineering as they conduct hands-on laboratory experiments and complete assignments that range from building a better mousetrap to assembling a digital circuit that operates a robot.

Johns Hopkins will continue to accept applications until June 1st, or until classes are full.

Top degree for S&P 500 CEOs? Engineering

See more recent post with data from 2005-2009: S&P 500 CEO’s: Engineers Stay at the Top

The most common undergraduate degree for CEO’s of Fortune 500 companies is Engineering: with 20% of all CEOs (from 2005 CEO Study: A Statistical Snapshot of Leading CEOs

Another interesting point from the report (at least to those of us who grew up in Madison with a father who taught at the University of Wisconsin (teaching Chemical Engineering, Industrial Engineering and Statistics, in my father’s case, by the way):

For the second year in a row, the University of Wisconsin joins Harvard as the most common undergraduate university attended by S&P 500 CEOs. Prior to 2004, Harvard alone was the most common school attended.

Engineering the Boarding of Airplanes

Airlines Try Smarter Boarding

“An airplane that spends an hour on the ground between flights might fly five trips a day,” he explains. “Cut the turnaround time to 40 minutes, and maybe that same plane can complete six or seven flights a day.” More flights mean more paying passengers, and ultimately, more revenue.
…
Convinced that there was a statistical solution to the problem, Lindemann approached Arizona State University’s industrial engineering department. “We have a great university in our backyard, and hoped they could help,”
…
Professor René Villalobos and graduate student Menkes van den Briel began reviewing boarding systems used by other airlines. “The conventional wisdom was that boarding from back to front was most effective,” says van den Briel. The engineers looked at an inside-out strategy that boards planes from window to aisle, and also examined a 2002 simulation study that claimed calling passengers individually by seat number was the fastest way to load an aircraft.

The two then developed a mathematical formula that measured the number of times passengers were likely to get in each other’s way during boarding. “We knew that boarding time was negatively impacted by passengers interfering with one another,” explains van den Briel. “So we built a model to calculate these incidents.”

Villalobos and van den Briel looked at interference resulting from passengers obstructing the aisle, as well as that caused by seated passengers blocking a window or middle seat. They applied the equation to eight different boarding scenarios, looking at both front-to-back and outside-in systems.
…
Villalobos and van den Briel presented America West with a boarding approach called the reverse pyramid that calls for simultaneously loading an aircraft from back to front and outside in. Window and middle passengers near the back of the plane board first; those with aisle seats near the front are called last. “Our research showed that this method created the fewest incidents of interference between passengers,” Villalobos explains, “and was therefore the fastest.”

A nice example of industrial engineering. And a clear example of the benefit of industry higher education cooperation.

Graduate Scholar Awards in Science, Technology, Engineering, or Math

From the proposed “Sowing the Seeds Through Science and Engineering Research Act” on the House Democratic Science Committee web site:

establishes the Graduate Scholar Awards in Science, Technology, Engineering, or Mathematics (GSA-STEM) program at the National Science Foundation (NSF). GSA-STEM is a graduate fellowship program providing 5000 new fellowships per year and modeled on the NSF Graduate Research Fellowship program. Each three-year fellowship awarded follows the student to his/her institution of choice, provides an annual $30,000 stipend, and provides a $15,000 fee to the institution in lieu of tuition. Selection of fellowship recipients follows the guidelines of the existing NSF fellowship program, except that special consideration is given to students who pursue advanced degrees in fields of national need, as determined by an advisory board established for GSA-STEM. Authorizes $225 million for NSF for FY 2007, $450 million for FY 2008, and $675 million per year for FY 2009 through FY 2011.

Updated, on May 8th, comparison of current related legislation (from the Democrat’s site – if there is a Republican alternative version I would be happy to post that, I just could not find a Republican summary – see more info on the Republican science committee “competitiveness” home page):

Competitiveness Report Recommendation: 5,000 new graduate fellowships each year in STEM areas of national need, administered by NSF. FY 2007,

President’s Competitive Initiative: No provision.

House Bills [Gordon]: H.R. 4596 tracks C-2 recommendation. FY 2007, $225 million.

House Bills [Boehlert]: No exactly equivalent provision. Explicitly authorizes the existing Integrative Graduate Education and Research Traineeship (IGERT) program, and authorizes NSF to accept funds from other agencies to carry out the DEd. FY 2007, $225 million.

Senate Bills [PACE, S.2197, S.2198, S.2199; and Lieberman, S.2109]: S.2198 tracks C-1 recommendation, except the program is administered by DEd. FY 2007, $225 million.
S.2109 provides for 250 new graduate fellowships each year. FY 2007, $34 million.

Nanowired at Berkeley

Nanowired by David Pescovitz:

“We’re attacking three fundamental issues,” Yang says. “Can we make these building blocks of nanodevices? Can we identify and harness useful physical properties in them? And can we integrate them in parallel? Individual devices are fundamentally interesting. But more importantly, we need massive numbers of them to work together as one system.”
…
The researchers demonstrated that minute voltages could control the flow of ions through the nanoscale plumbing system. In the future, the same technique might be used to shuttle proteins or pieces of DNA from a biological sample through the tubes in a lab-on-a-chip. Yang is currently developing a technique to conduct optical sensing within the nanofluidic channels so that the whole lab is self-contained in one device.

What Makes People Successful?

A Star Is Made – The Birth-Month Soccer Anomaly by Stephen Dubner and Steven Levitt (authors of Freakonomics (an interesting book):

If you then examined the European national youth teams that feed the World Cup and professional ranks, you would find this quirk to be even more pronounced. On recent English teams, for instance, half of the elite teenage soccer players were born in January, February or March, with the other half spread out over the remaining 9 months. In Germany, 52 elite youth players were born in the first three months of the year, with just 4 players born in the last three.

Why? Read the article by the Freakonomics authors for an explanation. In reading the article you get an example of why scientific thought is so important. The data can lead to all sort of conclusions, the article offers several:

a) certain astrological signs confer superior soccer skills; b) winter-born babies tend to have higher oxygen capacity, which increases soccer stamina; c) soccer-mad parents are more likely to conceive children in springtime, at the annual peak of soccer mania

The ability to examine such questions effectively is one of the benefits of learning to think scientifically. Then we can find sensible explanations instead of accepting crazy explanations. In this case the scientist, Anders Ericsson, is looking to learn how people become successful in a field. He concludes we far overestimate talent and far underestimate training and desire.

Electron Clouds

From my favorite science teacher blog, Ms. Frizzle, the Electron Cloud Analogy:

Okay, so suppose we wanted to draw a map of where Tiana is at 10 am on a Wednesday. We could draw the school, because we know exactly where that is, and we could draw this classroom inside the school. But how do we show where Tiana is? Is she always in exactly the same place at that time? No…. but we know where she is most likely to be: in this classroom, in science class, in her seat. But she sometimes changes seats, or gets up and moves to a different part of the classroom. And once in a while, she leaves the room
…
This is kind of like the electron cloud diagram – the darker areas tell you that the electrons are more likely to be there, although we don’t know that for absolutely certain, and the lighter areas are places where electrons could be, but more rarely.

Learning science from Ms. Frizzle sure seems like it would be fun.
