It’s been a busy week. Tuesday evening, I gave a lecture based on the new book (Me, Myself, and Why: Searching for the Science of Self) at Seattle’s Town Hall. And later today, I’ll be appearing at Politics and Prose bookstore in Washington, DC, so if you’re in the area around 3:30 PM, stop in and say hi. But Jen-Luc Piquant still managed to gather a collection of great physics links.
The Time Lord has been even busier. Last weekend we went to New Orleans so he could debate Christian apologist William Lane Craig; he shared his own take on how the event went, and you can watch the videos now, too, and make your own call.

A Fluid New Path in Grand Math Challenge, featuring the Cat in the Hat. Per Quanta: “UCLA mathematician Terence Tao “has shown that in an alternative abstract universe closely related to the one described by the Navier-Stokes equations, it is possible for a body of fluid to form a sort of computer, which can build a self-replicating fluid robot that, like the Cat in the Hat, keeps transferring its energy to smaller and smaller copies of itself until the fluid ‘blows up.’”
Also in Quanta this week: Physicists Eye Quantum Gravity Interface. Gravity curves space and time around massive objects. What happens when such objects are put in quantum superpositions, causing space-time to curve in two different ways?
Falcon Physics: The Science of Diving Peregrine Falcons. “By combining their wind tunnel analysis with the data from the video footage, the researchers created the most comprehensive analysis of a peregrine falcon dive to date, including factors such as lift, drag, acceleration, and trajectory.” Bonus: via Twitter I learned about the great video footage (via a bird-sized headcam) of falcons in flight taken by Haverford physicist Suzanne Amador Kane.

“The analysis shows that the story is characterized by a sudden explosion of sentimental involvements, revealed by the existence of a saddle-node bifurcation in the model. The paper is interesting not only because it deals for the first time with catastrophic bifurcations in romantic relation-ships, but also because it enriches the list of examples in which love stories are described through ordinary differential equations.”

“[Murphy] has worked out a unique set of notes for every station, one of which would sound each time a passenger swipes his or her MetroCard to catch a train. The busier a station becomes, the richer the harmonies would be. The same notes would also play in a set sequence when the subway arrives at that stop. Each of the city’s 468 subway stations would have note sets in different keys.”

20th-Century Math Hidden in 15th-Century Art. Artist Anita Chowdry “noticed the patterns [in Islamic illuminated manuscripts] are strongly reminiscent of fractal geometry and the famous images produced by Benoit Mandelbrot’s research on the topic in the late 1970s and 1980s. Upon realizing this, she embarked upon a journey to incorporate her knowledge of the ancient art of manuscript illustration with modern mathematical concepts and technology. The result is a spectacular collection of images and object.”
