This week, Quanta kicked off a five-part series on science and big data, starting with Imagining Data Without Division. Part 2: A Digital Copy of the Universe, Encrypted. As physics prepares for ambitious projects like the Large Synoptic Survey Telescope, the field is seeking new methods of data-driven discovery. Part 3 is my article on the Mathematical Shape of Things to Come. Scientific data sets are becoming more dynamic, requiring new mathematical techniques on par with the invention of calculus. Part 4 and Part 5 will appear next week.

When the Doppler Effect gets twisted. “In 1981, a chemist discovered that when light is circularly polarized, the polarization changes its frequency. What’s more, if the light then hits a spinning object, a rotating reflective surface or a spinning gas cloud, the light’s polarization and frequency changes again.”

Why Are There Still So Few Women in Science? Long, thought-provoking rumination by former Yale physics major Eileen Pollack explores why she opted out of physics graduate school: “I wanted to understand why I had walked away from my dream, and why so many other women still walk away from theirs.”
When it comes to popularizing science, women have been left on the sidelines as a laddish, macho presenting culture takes over, argues Sue Nelson. “Nowadays, it appears you can’t do mainstream popular science unless you’re fishing from the same pool of men. Unfortunately, the overall effect is a Top Gear for science, with blokes chatting about planets instead of Porsches.” Jen-Luc Piquant rather likes Top Gear. And Brian Cox and Dara O’Briain. As does Nelson. But it’s a thoughtful piece, and a valid point.
Feynman diagrams are like grains of sand. The physics behind this year’s Sakurai Prize for new techniques for calculating amplitudes. “An “amplitude” is the fundamental thing one wants to calculate in quantum mechanics — the probability that something happens (like two particles scattering) is given by the amplitude squared. ”
