This week there continued to be Ripples From the Big Bang. Sean Carroll discussed When Nature Looks Unnatural: “Ultimately it’s nature, not us, that decides what’s natural.” And Matt Strassler was back, explaining Which Parts of the Big Bang Theory are Reliable, and Why. Also: The gravitational-wave finding would strengthen case for multiverse and all but rule out a ‘cyclic Universe.’ And the contrarians have come out of the woodwork: Cosmologists Say Last Week’s Announcement About Gravitational Waves May Be Wrong. Finally, are we entering a golden era of private science funding? BICEP2 was prominently funded by Keck and Moore Foundations.
For the human interest angle, check out inflationary theory co-founder Andrei Linde showing off his bicep before giving a talk on the BICEP2 results. Inflation on the back of an envelope: Caltech’s John Preskill does some fast calculations. You know, for fun. To Discover Gravitational Waves, Someone’s Got to Keep the Antarctic Telescope Cold. That thankless task goes to Steffen Richter, among others. “We have a huge movie library. There are parties. People organize art shows.”
“[G]enerative artist and designer Jonathan McCabe, based in Canberra, Australia, is turning Turing’s theory into art. Instead of cells, McCabe starts with pixels. Each pixel gets a random value, usually a number between -1 and 1, which is represented in the final image by a color. Then, McCabe applies a set of rules that dictate how each pixel’s value shifts in response to the ones around it. As the program progresses, pixel values change, creating clusters of shapes that begin to emerge from the originally random mix of numbers.”

The World’s Smallest Sandcastles Built on Individual Grains of Sand by Vik Muniz and Marcelo Coelho.
“Muniz first drew each castle using a camera lucida, a 19th century optical tool that relies on a prism to project a reflection of whatever is in front of you onto paper where it can be traced. The drawings were then sent to Coelho who worked with a number of microscopic drawing processes for several years before deciding to use a Focused Ion Beam (FIB) which has the capability of creating a line only 50 nanometers wide (a human hair is about 50,000 nanometers wide). Lastly, Muniz photographed the final etchings and enlarged them to wall-sized prints.”

The match took place during the first annual Densei-sen, or “electronic holy war,” tournament, in Tokyo, where the best Go programs in the world play against one of the best humans. Ishida, who earned the nickname “the Computer” in the nineteen-seventies because of his exact and calculated playing style, described Crazy Stone as “genius.””
