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.
, when the first volume was available.)
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
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 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.

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

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
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
. 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

Physicist Freeman Dyson reviews two new books about Richard Feynman
, one about the science and one in graphic novel
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.
, and probably in the future, but not predictably so.
"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]
"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."

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]
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].
