Items for students and others, interested in learning about science and engineering and the application of science in our lives. We post many of the general interest items here.

Siemens Competition in Math, Science and Technology

Siemens Competition in Math, Science & Technology

Students may enter as individuals or as part of a team. Applications are due by 2 Oct, 2006. Up to thirty individual students and thirty teams (of 2 or 3 students) are chosen to compete at six regional competitions hosted by our partner universities MIT, Carnegie Mellon, Georgia Tech, Notre Dame, UT Austin and UC Berkeley.

Students who win their regional competition receive a silver medal and scholarships of $3,000 (team members receive $6,000 to be divided equally between team members) and go on to compete at the national event in New York City. The top individual and top team each receive $100,000 scholarships. Runners up receive scholarships ranging from $10,000 to $50,000.

UW- Madison Wins 4th Concrete Canoe Competition

Concrete Canoe Race

University of Wisconsin-Madison Takes First Place for 4th Straight year in 2006 National Concrete Canoe Competition:

This was no ordinary boat race. The competitors weren’t sleek sailboats riding the winds or high-powered yachts muscling their way across the finish line. These were canoes. Made of concrete. Hundreds of pounds of concrete. And the only thing propelling these water-worthy crafts was the determination of the engineering students that created them in a bid to win the ‘America’s Cup of Civil Engineering.’

Manipulating Carbon Nanotubes

Photo: At left, the high conductance state has two molecular orbitals, shown in green. Some molecules even let the nanotube switch between highly conductive, left, and poorly conductive. MIT materials scientists tame tricky carbon nanotubes:

Now Young-Su Lee, an MIT graduate student in materials science and engineering, and Nicola Marzari, an associate professor in the same department, have identified a class of chemical molecules that preserve the metallic properties of carbon nanotubes and their near-perfect ability to conduct electricity with little resistance.

Using these molecules as handles, Marzari and Lee said, could overcome fabrication problems and lend the nanotubes new properties for a host of potential applications as detectors, sensors or components in novel optoelectronics.

Middle School Engineers

Burnsville’s budding engineers?:

The exercise is part of a pre-engineering program called Project Lead the Way, which aims to whet students’ appetites for engineering education and possibly careers.

Through a Kern Family Foundation grant, District 191 is providing PLTW in seventh grade this year, with plans to extend it to eighth grade next year and possibly to the high school level in subsequent years.
…
“Problem-solving is the rest of their lives,” she said. “If they’re seeing the relevance between the math they’re learning out of a book and a project they’re doing, it sticks.”

Great stuff. Getting kids to actually apply concepts is not only fun but the best way to learn.

Google Computer Science Scholarship Program

United Negro College Fund (UNCF) Google Scholarship Program:

On the strength of candidates’ academic background and demonstrated leadership, we’ll be awarding $5,000 scholarships. Students must be enrolled in their junior year of undergraduate study at a UNCF Member College or University or at a participating Historically Black College or University (HBCU), and pursuing a Computer Science or Computer Engineering major.

The application deadline is October 6th. Previous posts on fellowships and scholarships in science and technology including: NSF Graduate Research Fellowship (deadline early November) and the proposal for Graduate Scholar Awards in Science, Technology, Engineering, or Math.

Turning Trash into Electricity

Florida county plans to vaporize landfill trash:

The $425 million facility expected to be built in St. Lucie County will use lightning-like plasma arcs to turn trash into gas and rock-like material. It will be the first such plant in the nation operating on such a massive scale and the largest in the world.

Supporters say the process is cleaner than traditional trash incineration, though skeptics question whether the technology can meet the lofty expectations.

The 100,000-square-foot plant, slated to be operational in two years, is expected to vaporize 3,000 tons of garbage a day. County officials estimate their entire landfill — 4.3 million tons of trash collected since 1978 — will be gone in 18 years.

No byproduct will go unused, according to Geoplasma, the Atlanta-based company building and paying for the plant.

Synthetic, combustible gas produced in the process will be used to run turbines to create about 120 megawatts of electricity that will be sold back to the grid. The facility will operate on about a third of the power it generates, free from outside electricity.

Engineering Delivery Systems to the Brain

Engineering a ‘Trojan horse’ to sneak drugs into the brain by Terry Devitt:

Using engineered yeast as microscopic factories to produce human antibodies customized to recognize the surface features of cells that compose the blood-brain barrier, Shusta has developed a set of unique antibodies that may one day be used to ferry drugs to specified regions of the brain.
…
With roughly 400 miles of blood vessels, the human brain is equipped with its own expansive delivery network for therapy – provided scientists are able to figure out a way to get past the blood-brain barrier. With different cell surface features in different parts of the circulatory system and also in different regions of the brain, it might be possible to customize antibodies to carry drugs to only those parts of the brain that would benefit from treatment.

Security of Electronic Voting

Security Analysis of the Diebold AccuVote-TS Voting Machine

This paper from Princeton University examines the security issues involved with electronic voting machines. The The consensus of the computer security community seems to be that they are not secure and should not be used as they currently exist. Yet for some reason they are being used.

It strikes me as similar to the uproar are the butterfly ballot scandal. Then the public learned that every year millions, of ballots were discarded as unusable and neither party had done much to fix the systemic problems. And then, when the problem was brought to the attention of the public, the parties acted as though this were some unforeseeable problem. They knew the system didn’t work and didn’t fix it. It seems to me the current electronic voting machines are an example of continuing this behavior. It would be better if they would listen to the scientists and not use a system which was so susceptible to creating a scandal.

Computer scientists have generally been skeptical of voting systems of this type, Direct Recording Electronic (DRE), which are essentially general-purpose computers running specialized election software. Experience with computer systems of all kinds shows that it is exceedingly difficult to ensure the reliability and security of complex software or to detect and diagnose problems when they do occur. Yet DREs rely fundamentally on the correct and secure operation of complex software programs. Simply put, many computer scientists doubt that paperless DREs can be made reliable and secure, and they expect that any failures of such systems would likely go undetected.

The man who saved geometry

The man who saved geometry by Siobhan Roberts:

Coxeter’s legacy is the powerful push he gave the visual geometric method, and the resulting change in perspective that transformed the way mathematicians and scientists create and investigate. “Coxeter’s perspective and ideas are in the air we breathe,” said Ravi Vakil, at Stanford. “It’s not that his ideas are used to solve problems, it’s that the fundamental problems grow out of his ideas. He’s the soil.”
