For those who don’t hang out much on Google+ (and also for those who do), the Time Lord (a.k.a. Caltech physicist Sean M. Carroll) and I did a live hangout with Read Science, co-hosted by my fellow SciAm blogger Joanne Manaster. Apparently there are lots of people who don’t realize that we’re married; hence Joanne’s nicknaming us a “Sci-Comm Power Couple.” Just call that public entity “Seannifer,” I guess.
Yesterday we celebrated Albert Einstein’s birthday. Did you know that Einstein rejected the big bang, black holes, and dark energy? Here’s why. Brain Pickings marked the occasion by reminding us of the wonderful children’s book, On a Beam of Light: The Story of Albert Einstein, Illustrated by the Great Vladimir Radunsky. Related: Einstein’s tongue – a picture from the past. (The story behind that famous photograph) Also: A Chat with “Einstein’s Girl” Gia Mora: “I want everyone to know that physics is a language we all can understand, and learning science from a non-scientist proves to my audience that they too can appreciate the universe in this new way.”
Physics Rumor Mill Buzzing About Gravitational Waves: Einstein Was Right, Again, Maybe. Cosmologists hope for a field-rocking announcement next week. Have US scientists heard echoes of the big bang? Trenches of Discovery has more on those BICEP2 rumors: “If … true, this would be a result immense in its significance.”
Einstein’s birthday just happens to coincide with Pi Day. Here, for your viewing pleasure, is the Guardian‘s slideshow of Pi transformed into striking computer-generated images. For example, Walking on Real Numbers (pictured at right): “Francisco Aragón and his colleagues converted pi into base 4, meaning that it is written using only the digits 0, 1, 2 and 3, and with these digits representing north, south, east and west, tracked a random walk of pi for 100 billion digits.” There’s even a paper based on their work (PDF).
The Time Lord wrote an illuminating post on the Einstein/Pi connection, revealed at last. There’s more than a celebratory day shared between them. Wired tells you how to Calculate Pi For Pi Day, while the Perimeter Institute offers a bunch of things you might not know about Pi (PDF).
For more of a humanities bent, Alex Bellos ruminates on Shakespeare, Jane Austen and the poet laureate of pi, while Matt Francis pays tribute to Euler: “the i and the pi.” Finally, if you’re feeling peckish, here’s How Alcohol Makes A Flakier Pie Crust: The “Proof” Is In The Pie.
Ooh! Math fight! Detractors say pi really is half-baked. Many want to replace it with the more mathematically sensible Tau. But over at Slate, Phil Plait disagrees, nixes replacing Pi with Tau, for pragmatic reasons. “Rebooting the use of a fundamental constant is utterly hopeless.” Here, let Vi Hart explain:
Here’s another sore subject when it comes to math. The Fraud of Vedic Maths: “Those who seriously still think ancient India had devised a parallel mathematical system need to acquaint themselves with an inventive Shankaracharya called Bharti Krishna Tirthaji.”
Sunday was the long-awaited premiere of the Cosmos reboot, starring Neil de Grasse Tyson. I’ll be writing recaps of each episode for the Los Angeles Times; the first one is here. Related: Shut Down Everything: Somebody Filmed Their Daughter Reacting to Cosmos, and it’s adorbz. Also: The Cosmos science advisor shared what its like consulting for Hollywood.
Not everyone was happy with the episode. Most of the ire seemed to center on the segment featuring Giordano Bruno, such as this take by Corey Powell over at Discover, with a follow-up counterpoint from Steven Soder, a co-writer of the episode, who also is a research associate at the American Museum of Natural History. Related: Before Galileo, before Giordano Bruno, there was the infinite cosmology and theology of Nicolas of Cusa.
While the top ratings of the night went to The Big Bang Theory (just renewed for three more seasons), Cosmos did pretty well, especially if you add up all the other channels on which it aired. According to the Los Angeles Times, science seems to be having a cultural moment: Craig Ferguson will be producing a new series for the Science Channel, I F-ing… Love Science, based on the popular Facebook page/Internet juggernaut.

Think watching ice melt would be dull? Think again. Per New Scientist: “A time-lapse video by photographer Shawn Knol brings out scintillating hidden structures using two polarising filters and an extreme close-up view. Knol uses an LED computer monitor as a polarised light source, then attaches a circular polarising filter to his camera’s macro lens. Rotating the filter creates the rainbow effect as varying thicknesses of ice refract the light differently.” Related: Mathematical Patterns in Sea Ice Reveal Melt Dynamics.

Meet Stephen Morris and his Online Ice Atlas, which may help solve the mystery of why icicles have ripples. “Most likely, the secret to the icy formation has something to do with the fact that the ice in an icicle isn’t all ice…. Water that forms icicles is supercooled, meaning it’s colder than freezing. In hailstones and ice that forms on power lines, this supercooled water makes ‘spongy ice.’ Not all of the water freezes solid. Some gets quarantined as a liquid in little icy compartments.”
