This week on Virtually Speaking Science, I chatted with Drexel University physicist Dave Goldberg, who writes the io9 “Ask a Physicist” column and is the author of one of my fave physics books of 2013, The Universe in the Rearview Mirror. You can listen to it here. Also, Jen-Luc made Buzzfeed’s list of 25 Must-Follow Twitter Accounts For Science Nerds; she is honored to be included in such august company.
Hawking questions nature of black holes in new paper on the arXiv, postulating that the notion of an ‘event horizon’ is incompatible with quantum theory; Info that goes into black holes comes out chaotically and isn’t lost. But retrieving it is like predicting weather.
After a teensy bit of a delay — hey, we don’t like to wake up on a Monday morning either — Rosetta, the Comet-Chaser, is awake! “I think it was the longest hour of my life,” said scientist Andrea Accomazzo. :There’s a really great animation here showing the long and loopy route of Rosetta so far, along with 7 Things You Didn’t Know About Rosetta, such as, the “Orbiter boasts 24 thrusters to control its motion and orientation.”
Journalist Janet Malcolm is also a collage artist. According to Slate, “Her most recent collection, “The Emily Dickinson Series,” juxtaposes clippings of Dickinson’s “fragment” poems, taken from scholar Marta Werner’s 1996 book Emily Dickinson’s Open Folios, with pieces cut from astronomy textbooks, found photographs, and other ephemera.” Her work is currently on display at the Lorie Bookstein Fine Art Gallery in New York City.

The debate on infinite series rages on! Phil Plait posted a clarifying follow-up, and Evelyn Lamb also weighed in with an excellent explanatory post.: The Infinite Series and the Mind-Blowing Result … Does 1+2+3… Really Equal -1/12? @evelynjlamb weighs in with an excellent post. Meanwhile, Physics Buzz took a more controversial stance: “Yes, there’s a problem with 1 + 2 + 3 + 4 + . . . = −1/12. The problem is with our failure to understand infinity.” And mathemtician Terry Tao weighed in with both a highly technical post at his blog, and a more lay-friendly version on Google+.
And here’s another bloggy debate that raged this week: The Curious Wavefunction asked: Should physicists stop looking for fundamental laws? Chad Orzel of Uncertain Principles took issue with a few of those points, prompting a response from The Curious Wavefunction and yet another counter by Chad. We eagerly await the next round.

Some thoughts on the science of queueing. Queuing theory “refers to the science that has its focus on reducing delays, irrespective of where they may be experienced: at a traffic signal; over the phone to speak to a representative (music and ads playing in the background); or, more critically, in a virtual queue of hundreds of patients, each waiting for an organ transplant.”

Photographing Time – Gorgeous photographic slideshow on the speed of photography through the ages, including this astonishing capture of light in motion. “Ramesh Raskar and his ream at MIT used a modified streak tube to capture the movement of a single pulse of light from a femtosecond laser across a screen, in this case a tomato against a wall. The laser light served as both flash and subject, and lasted just two trillionths of a second.”

Emptied Gestures: Physical Movement Translated into Symmetrical Charcoal Drawings by Heather Hansen. “Her body contorts into carefully choreographed gestures as her writing implements grate across the floor, the long trails resulting in a permanent recording of her physical movements. Part dance and part performance art, the kinetic drawings are a way for Hansen to merge her love for visual art and dance into a unified artform. The final symmetrical patterns that emerge in each pieces are reminiscent of a Rorschach test, or perhaps cycles found in nature.”

Watch Where I’m Going: Predicting Pedestrian Flow. “Researchers with Siemens and the Munich University of Applied Sciences examined video recordings of commuters walking through a major German train station on a weekday, during both the morning and evening peak commute times. Scientists analyzed the videos to determine individual pedestrians’ paths and walking speeds, and used the resulting data to set the parameters for a simulation of pedestrian traffic flow. ”
