Sasha Frere-Jones,  the pop-music critic of The New Yorker, writes about I Am T-Pain, a new iPhone application from Smule that is getting something like 10,000 downloads a day.

Smule, a company that specializes in sonic iPhone apps, was cofounded by Princeton Engineering alum Ge Wang. Hear Ge talk about Smule and about his philosophy of invention in the video above. The Ge profile is by Michael E. Wood '08, who has created a video library of interviews with prominent Princeton Engineering alumni.

Last week, Princeton’s Keller Center hosted a panel titled “iPhone Apps: the New high-tech Gold Rush.” The panel included Princeton Engineering alum David Lieb of Bump Technologies and Matt Conner, an operations research and financial engineering major at Princeton who recently won a $100,000 grant to develop iPhone app that helps diabetics manage their disease.

Princeton engineers are building a 92-foot-long replica of the Golden Gate Bridge as part of a $3 million National Science Foundation interactive display that will open in 2012.

Assistant professor Maria Moreyra Garlock is leading the model-building project along with Sylvester Black (pictured in the photo at right), who graduated from Princeton Engineering last year and who did his senior thesis on the Golden Gate bridge.

Interestingly, before the Golden Gate bridge was built, Princeton engineering professor George E. Beggs made and tested a steel model of the bridge tower, built to a scale ratio of 1 to 56. According to the Engineering News-Record of January 25, 1934, Beggs reported his results to some 200 engineers. HIs conclusion? The bridge was sound.

Garlock's colleague and mentor, the legendary David Billington, is interviewed in the current issue of Boston Architecture. In the interview, Billington talks about bridges (naturally), teamwork, and the importance of imagination in engineering. In the video below, Garlock discusses an exhibit on the mid-20th century structures of Felix Candela, which she and Billington co-curated. The exhibit features models of Candela's work created by Princeton students.

The Keller Center has just posted its spring list of of cutting-edge technology courses, all of which are taught by exceptional teachers and designed to appeal broadly to all undergraduates.

Michael Gordin,  the author of a new history of the Cold War as well as a recent essay in the Los Angeles Times on the United Nations and nuclear arms control, will be teaching a keystone course called Technology and Society.

Why should non-techie undergraduates care about technology? Because virtually all the problems the world faces have some kind of technological dimension. And why should techie undergraduates care about society? Because the deployment of technology always has societal repercussions. But don't take EQN's word for it -- you can hear from Gordin directly in the video above.

A centerpiece of the Keller Center's mandate is to ensure that all students at Princeton gain a clear appreciation of technology and the social and political forces that shape it. To that end, Princeton undergraduates will find spring course offerings in engineering and community service, in entrepreneurship, and in a range of topics at the intersection of technology and society, from alternative energy to the computational universe.

By the way, one of Princeton Engineering's most prominent alumni, Google CEO Eric Schmidt, recently remarked that he was  attracted to Princeton precisely because its engineering school was embedded in a liberal arts setting.  "I believed that the value of a liberal arts education would serve me in some inchoate way," says Schmidt. "That has proven true."

You can watch a 3-minute feature video profile of Schmidt here or on Youtube. It is part of a library of engineering alumni videos  created by Michael E. Wood '08.

"In recent years," writes Bialik, "statisticians have created time machines to answer a wide range of historical hypotheticals, from how today's Supreme Court would have voted on Roe v. Wade to what sort of scientific papers Einstein might write today."

One of the researchers highlighted in the article is Princeton computer scientist David Blei, who has done a computational analysis of more than a hundred years' worth of Science magazine.

This is how Bialik describes Blei's research:

"His system identifies topics from scratch and assigns topic scores -- say, 80% neuroscience and 20% philosophy, or 40% biology and 60% chemistry. Any papers that have the same topic scores could then be grouped together, even if they are decades apart and keywords or concepts didn't yet exist. (Think of quarks or H1N1.)

"Here the critical bridge -- the necessary overlap to relate past decades to the present -- were keywords that were associated with others before they faded... Such techniques connected an 1880 paper on orangutan brains with a 1976 paper on monkey brains.

"That technique helps dig up research that was ahead of its time. For instance, these very time machines, including Dr. Blei's, make use of so-called Bayesian statistics, which were developed decades before there was sufficient computing power to use them fully."

You can hear Blei talk about his work in this 2007 Google Tech Talk. Blei's recent research includes papers on "finding latent sources in recorded music," "a computational approach to style in American poetry," and "augmenting social networks with text" -- this last paper being coauthored with former student Jonathan Chang, now at Facebook, who in a recent blog post describes various visualizations he created of theonion.com's twitter traffic.

"Dan Warmenhoven is not only a highly talented and creative technology leader, he is one of Silicon Valley's finest community leaders," said Carl Guardino, president and CEO of the Leadership Group. "Along with his wife Charmaine, their contributions to the arts, the culture and the needy in Silicon Valley set the standard that each of us should try to emulate."

The group also honored Stanford President John Hennessy. Among the thousand or so Silicon Valley glitterati at the event were California Governor Arnold Schwarzenegger and senators Dianne Feinstein, and John McCain.

Both Dan and Charmaine Warmenhoven earned their undergraduate degrees from Princeton -- his in electrical engineering, hers in psychology. Read more in the Silicon Valley Business Journal and the San Jose Mercury News.

The Princeton Alumni Weekly this week has a fascinating profile of bioengineer John Dabiri, who graduated from Princeton Engineering in 2001.

Last year Popular Science magazine named Dabiri one of its "Brilliant 10," dubbing him the "jellyfish engineer." By studying the way that jellyfish propel themselves through water, Dabiri draws inspiration for a range of engineering challenges, from designing energy-efficient underwater vehicles to developing a new method for early diagnosis of heart disease.

Dabiri, who majored in mechanical and aerospace engineering at Princeton, is now a researcher at CalTech and has also been featured recently by Time, The Epoch Times, Environmental Research, and Ecoworldly.

"Scientists have proved that it is possible to create complex financial bundles (you know - bundles of mortgages that have 'a few lemons' that are supposed to average out and make the whole bundle great investment) that hide bad assets in such a way that no computer or human can detect the bad assets."

Worse, the blog continues, "Even after a buyer loses their shirt on the investment, it is impossible for the buyer to prove that they were sold junk, which makes it impossible to regulate."

The paper is Computational Complexity and Information Asymmetry in Financial Products by Sanjeev Arora, Boaz Barak, Markus Brunnermeier, and Rong Ge. Arora and Barak are with Princeton's Center for Computational Intractability and coauthors of Computational Complexity: A Modern Approach, published earlier this year by Cambridge University Press.

Computerworld recently profiled Princeton's legendary Brian Kernighan, who in 1978 wrote the now-classic C Programming Language  with C's creator, Dennis Ritchie. You can follow the slashdot conversation about the Kernighan profile here.

The book has sold millions of copies and been translated into a couple dozen languages, including Hebrew, Finnish, and Albanian. The screen grab above, from Kernighan's website, shows the covers of different translations. 

Kernighan -- who earned his doctorate from Princeton in 1969 -- teaches the very popular Computers in Our World course, which The New York Times's Steve Lohr wrote about a few years back in a piece called "To the Liberal Arts, He Adds Computer Science". Kernighan is also a regular columnist for the Daily Princetonian and recently last year wrote an essay for an IEEE publication delineating what every educated person should know about computers. 

By the way, Kernighan helped inspire the name for this blog.

Technology Review this month reports on new types of conductive inks being produced by Vorbeck Materials Corp. that can be used to print RFID antennas and electrical contacts for flexible displays. 

The inks are made from graphene,  the most stable form of carbon on Earth, using a technology developed by Princeton's Ilhan Aksay. Vorbeck, which just received $5.1 million in financing from private-investment firm Stoneham Partners,  was started by Princeton Engineering graduate John Lettow, who did his senior thesis research under Aksay. Read the full TR piece here.

"Bio-derived fuels must be fully compatible with petroleum fuels, particularly for aircraft applications, because of the international nature of the aviation industry," writes Dryer, who is professor of mechanical and aerospace engineering.

In June, Dryer gave a talk on his combustion research as part of a larger workshop on energy and the environment sponsored by Princeton's Andlinger Center. You can watch the full workshop here. Award-winning science journalist Patrick Regan of NJN-News also covered the workshop and produced another piece on combustion science at Princeton.

Regan produced those pieces just before leaving NJN to explore new frontiers in Munich, Germany. His exemplary science reporting will be sorely missed. Regan's coverage of Princeton Engineering included pieces on new lasers, river biodiversity, nanojet printing, a robotics competition, and Princeton's Science Olympiad.

The current issue of New Scientist magazine reports on two new mathematical models created by Princeton Engineering postdoctoral researcher Manoj Srinivasan demonstrating that airport "people movers" -- those human conveyor belts that propel passengers from point A to B -- tend to slow down travelers. 

"Srinivasan's models predict that when a person steps onto a moving walkway, they slow their foot speed by about half the speed of the walkway," reports MacGregor Campbell in the New Scientist. "This suggests that our desires to conserve energy and to resolve the conflict between visual cues and leg muscle signals -- your eyes tell you that you are going faster than your legs are taking you -- slow us down so that our total speed is only slightly greater than it would have been on regular ground."

When the airport is congested, as it often is, this means that travelers would get wherever they are going faster if they just walked.

The Daily Telegraph also reports on the research.
