Physics With a Twist

Physics Week in Review: October 5, 2013


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.

Writer David Quigg asked the FBI if he could see some Hemingway files with less blocked out. The FBI actually agreed. That's how Quigg discovered how a 1918 meeting between an astronomer, Harlow Shapley, and Robert Frost led to Frost’s famous poem, “Fire and Ice.”

This Tower Exists Solely for Dropping Things -- for SCIENCE!

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."

New York Times Opinion Column by Columbia University philosopher Stephen Asma Equates Higgs, Genes, Evolution with Feng Shui, Qi, and Turtle Blood. This is, of course, nonsense.

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.

The American Physical Society awarded some Pre-Nobel prizes. Matt Strassler has the scoop. Physics Buzz lists a few possibilities for the 2013 Nobel Prize in Physics.

"It might look like gibberish to you, but every term in the analytic formula for the gg → ggg scattering amplitude told us something." -- Lance Dixon.

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. "

Related: Scott Aaronson worries scattering amplitudes might be simple for simple theories, harder in general.

Peter Higgs profile: the self-deprecating physicist is revered by his peers. Particle physicists speak of admiration for man who outlined what came to be known as Higgs mechanism.

Particles and the People Who Love Them: Documentary Shows the Human Side of the Large Hadron Collider. "Particle Fever shows the human drama behind the physics drama in a way that is hard to experience if you weren’t actually there in the control room when the accelerator beams were first turned on, or in the great lecture hall when the conclusive data were first projected on the wall."
