Shut up and calculate...

What does any of this have to do with physics? An excellent long form essay on graduate school in physics.

Richard shared a photon with you!

Let’s draw Feynman diagrams! (Part 1 of 20) You do not need to know any fancy-schmancy math or physics to do this! That’s right. I know a lot of people are intimidated by physics: don’t be! Today there will be no equations, just non-threatening squiggly lines. Even school children can learn how to draw Feynman diagrams (and, I hope, some cool science). Particle physics: fun for the whole family.

All three volumes of The Feynman Lectures on Physics are now online.

The Feynman Lectures on Physics All three volumes of The Feynman Lectures on Physics are now online. A fantastic resource for anyone interested in Feynman or physics in general. (Previously, when the first volume was available.)

My God, it's full of... everything

Revelations in the field of quantum physics have resulted in the discovery of the Amplituhedron, a jewel-like higher dimensional object whose volume elegantly predicts fundamental physical processes that took the brilliant Dr. Richard Feynman hundreds of pages of abstruse mathematics to describe. The theoretical manifold not only enables simple pen-and-paper calculation of physics that would normally require supercomputers to work out, but also challenges basic assumptions about the nature of reality -- forgoing the core concepts of locality and unitarity and suggesting that space and time are merely emergent properties of a timeless, infinitely-sided "master amplituhedron," whose geometry represents the sum total of all physical interactions.

Photons: Corpuscules of Light.

Richard Feynman delivers a charming talk about Quantum Mechanics and Quantum Electrodynamics and the versatile, enigmatic photon. (SLYT - 1:17:58)

"The game I play is a very interesting one. It's imagination, in a tight straitjacket."

From 1981 - 1993, documentary producer Christopher Sykes created three films about Dr. Richard Feynman. All are now available in their entirety on YouTube: Richard Feynman: No Ordinary Genius, The Pleasure of Finding Things Out and Last Journey of a Genius (previously). [more inside]

A Grand Adventure

When Richard Feynman was a young boy his father told him of the remote land of Tannu Tuva, igniting an obsession that would remain with him for the rest of his life. The Last Journey of a Genius chronicles Feynman’s attempts to get to the country at the geographic center of Asia, all stymied by the Iron Curtain, although he did correspond with some of its citizens and was a fan of its distinctive music and stamps. A visa for Tuva finally arrived days after his death.
Most would suggest that the story ends there, but not so: Feynman’s friend Ralph Leighton eventually made it, and formed the Friends of Tuva; later, Feyman’s daughter Michelle made the trip her father planned but never completed, an emotional journey recorded by the Russian service of the BBC [MP3].

Fine Feynman Fare

Physicist Freeman Dyson reviews two new books about Richard Feynman, one about the science and one in graphic novel form.

He never showed the slightest resentment when I published some of his ideas before he did. He told me that he avoided disputes about priority in science by following a simple rule: "Always give the bastards more credit than they deserve." I have followed this rule myself. I find it remarkably effective for avoiding quarrels and making friends. A generous sharing of credit is the quickest way to build a healthy scientific community.

Feynman at his best

"Fun To Imagine" is a BBC series from 1983 featuring theoretical physicist Richard Feynman thinking aloud. What is fire? How do rubber bands work? Why do mirrors flip left-right but not up-down? All is explained in his lovely meanderingly lucid manner. [more inside]

Surely not joking, Mr. Feynman

"I can see the audience tonight, so I can see also from the size of it that there must many of you here who are not thoroughly familiar with physics, and also a number that are not too versed in mathematics- and I don't doubt that there are some who know neither physics nor mathematics very well. That puts a considerable challenge on a speaker who is going to speak on the relation of physics and mathematics- a challenge which I, however, will not accept: I published the title of the talk in clear and precise language, and didn't make it sound like it was something it wasn't- it's the relation of physics and mathematics - and if you find that in some spots it assumes some minor knowledge of physics or mathematics, I cannot help it. It was named." The Feynman Messenger series at Cornell has been made available online for the first time thanks to Bill Gates.

R.I.P. John Wheeler, physicist

R.I.P. John Wheeler, theoretical physicist. Famous for the Wheeler-Feynman equations and the term "black hole," which he coined to describe a singular point mass, he has died at age 96. The NYT usually gives pretty good obituary but they outdid themselves this time. [more inside]

Odd but fun short films...

The odd films of Neural Surfer. I've yet to watch them all but my fave so far is Little Things that Jiggle: Richard Feynman and Atomic Physics {google vid}, which is part of the Philosophy in less than five minutes (sometimes) series.

The pleasure of finding things out

The pleasure of finding things out. If you only watch one documentary on the subject of science this year, let is be this one. The brilliant physicist Richard Feynman is interviewed about a host of issues, such as [more inside].
