Got this notice from MSRI: ----- NOVA’s The Great Math Mystery Wednesday, April 15, 2015, at 9 p.m. on most PBS stations (check local listings to confirm date and time for other cities, as schedules may vary) Join NOVA on a mathematical mystery tour—a provocative exploration of math's astonishing power across the centuries. We discover math's signature in the swirl of a nautilus shell, the whirlpool of a galaxy, and the spiral in the center of a sunflower. Math was essential to everything from the first wireless radio transmissions to the prediction and discovery of the Higgs boson and the successful landing of rovers on Mars. Astrophysicist and writer Mario Livio, along with a colorful cast of mathematicians, physicists, and engineers, follow math from Pythagoras to Einstein and beyond. It all leads to the ultimate riddle: Is math a human invention or the discovery of the language of the universe? (Please visit http://www.pbs.org/wgbh/nova/physics/great-math-mystery.html for more details.) ----- It is, perhaps, not such a good idea to use an astrophysicist to expound on math, especially this astrophysicist, who wrote a book about the golden ratio filled with misinformation. --Dan
