This week on Virtually Speaking Science, I chatted with astrophysicist Katie Freese, author of a new book, The Cosmic Cocktail: Three Parts Dark Matter. Also, regular readers may have noticed I’ve been recapping episodes of the new WGN America series, Manh(a)ttan, each week (Part 1, Part 2, Part 3) — the best new show you’re probably not watching. But you should. It’s about the Manhattan Project in the same way Buffy the Vampire Slayer was about vampires. Sure, it’s the bulk of the narrative arc, but it also provides a great metaphorical backdrop. The show is about so much more than the race to invent the first atomic bomb.
It was a big week for the math world, with the announcement of the winners of the 2014 Fields medal – the ‘Nobel prize of math.’ Quanta ran a special series profiling each of the winners. Among them: the first woman to win the medal in its entire history, A Tenacious Explorer of Abstract Surfaces: Maryam Mirzakhani. ‘The more I spent time on maths, the more excited I got.’ Then there was Artur Avila: A Brazilian Wunderkind Who Calms Chaos, and Martin Hairer: In Noisy Equations, One Who Heard Music. Also: A Grand Vision: Subhash Khot’s bold conjecture is helping mathematicians explore the precise limits of computation. Finally, there was the Musical, Magical Number Theorist: Manjul Bhargava. Related: The math of Avila, Bhargava, Hairer and Mirzakhani explained, via the Guardian.

Funky toe hairs allow geckos to turn stickiness on and off. (Funky Gecko Toe Hairs = the name of Jen-Luc Piquant’s next band) No, seriously, new research investigates the physics of sticky gecko feet. What gives geckos the remarkable ability to run upside down across ceilings and stop short on smooth vertical surfaces? The Los Angeles Times says you could call it “the hierarchy of hairs.” Special thanks to JPL’s Bobak Ferdowski (a.k.a. Mohawk Guy, or @tweetsoutloud) for tipping me off to JPL’s “Gecko Gripper”, which helps robots navigate low gravity environments.

It was Erwin Schrodinger’s 127th birthday, and the folks at the Perimeter Institute celebrated with this “unique look at the most famous thought experiment of quantum physics, in which an unfortunate (and, rest assured, purely hypothetical) cat sacrifices its life, yet also doesn’t, for the sake of science.” It’s part of the documentary The Quantum Tamers: Exploring Our Weird & Wired Future.

The Physics of the Railgun. “The device is simple in design. You have two parallel rails (thus called a railgun) and a moveable projectile that is also like a wire. An electric current goes down one wire, across the projectile and then back down the other rail. In between the two parallel rails, both of the magnetic fields due to the rails points in the same direction and make a stronger magnetic field. This magnetic field then pushes on the projectile with the current running through it to propel it out of the railgun. Boom. A projectile.”
Supermoon and Persied meteor shower, together at last! Astronomers and amateur skywatchers were totes excited as perigee moon and comet Swift-Tuttle appeared together for dazzling skies. The supermoon got its name because it appears about 14% bigger and 30% brighter than an average full moon. The Perseid Meteor Shower Thrilled Stargazers Despite the Bright Moon. There were lots of pictures, as well as teh science. “I heard the Super Moon causes hemorrhoids.” Phil Plait (@BadAstronomer) recommends tinfoil hats.

It spins so rapidly no one could work out why it hadn’t pulled itself apart long ago. Now the mystery has a solution, and it seems the asteroid is using a similar trick to geckos climbing glass walls, with implications for how to tackle objects that might threaten the planet.”

Via Colossal: “Australian artist Andy Thomas creates what he describes as “audio life forms,” specifically 3D animations that respond to audio input. For these latest pieces he used archival bird recordings from the Netherlands Institute for Sound and Vision (in addition to one of his own recordings) to create these new digital sound sculptures that animate in different ways in reaction to the songs of each bird.”
Stephen Hawking’s Dazzling Life Becomes a Movie — But What Sort of Movie? “It’s important that even an exemplary, heroic life can still be messed up, ferocious, flawed and broken — but not so broken that it isn’t beautiful. That’s the thing to remember about Stephen Hawking — that he gambled everything, and then, in his own way, he won, and lost — like all the rest of us.”

The Schiller Effect Makes Stone Seem to Light Up Internally. “The best way to picture the physics of it is imagining the streak of light off an old record, always perpendicular to the grooves in the vinyl. Another good way to understand the effect is to picture the glitter path that appears on the ocean when light from the moon hits it. The path of the light is always perpendicular to the waves, as their angle to the incoming light reflects it back towards the onlooker.”
