Neutrinos faster than light – Sixty Symbols

As the current big news in science is the discovery of the neutrinos traveling faster than the speed of light. Here we have physicists from the University of Nottingham offering some explanations and possibilities for the neutrinos to behave that way.

For more information about neutrinos themselves you can take a look at the Hunting for Neutrinos documentary.

Garrett Lisi: A beautiful new theory of everything

“For the next 18 minutes I’m going to try to explain the beauty of particle physics without equations”, that is how physicist and surfer Garrett Lisi starts this lecture, and he sure does. He presents a controversial new model that could answer some big questions. His theory¬†gives us a pattern, or layout for sub-atomic particles (similar to the periodic table of elements). DISPROVED: This theory has been disproved in the meantime, although Lisi updated the theory and published new papers. You can read about it on Wikipedia. Thanks to Jeff Milne for pointing that out.

Tour of the Electromagnetic Spectrum

The electromagnetic (EM) spectrum is just a name that scientists give a bunch of types of radiation when they want to talk about them as a group. Radiation is energy that travels and spreads out as it goes– visible light that comes from a lamp in your house and radio waves that come from a radio station are two types of electromagnetic radiation.
This is a very nice short movie series from the ScienceAtNASA YouTube channel, explaining the basics of the EM spectrum. Going from the introduction to each type of EM waves in a bit of more detail. Well worth the watch.

Parallel Universes

This is 2001 BBC Horizon documentary film mostly dealing with string theory, M-theory, supergravity and the existence of parallel universes, each one a bit different from the other, with different histories, different event and different laws of physics, thus assuming that everything will happen somewhere, sometime in some universe. Even the same people exist in multiple universes, where their lives may be drastically different, or may even not exist at all…thus encompassing all the possible universes, all possible realities in one multi-verse.
Participants in the documentary include Michio Kaku and Paul Steinhardt.

Hunting for Neutrinos

This is a CERN documentary about the neutrino, an elementary particle that usually travels close to the speed of light, is electrically neutral, has close to zero mass, and is able to pass through ordinary matter almost undisturbed. Naturally such properties make it extremely difficult to detect so this documentary also covers the scientific methods involved in hunting down the neutrino.

Stanford: Quantum Entanglements by Prof. Leonard Susskind

This is a series of lectures from Stanford University, concentrating on Quantum Entanglements. Lecturer is Professor Leonard Susskind, a professor of theoretical Physics at Stanford University, probably best known for his confrontation with Stephen Hawking on the nature of black holes.
Here we have a series of 9 lectures, each almost 2 hours long, enjoy.
