The title says it all: this blog features physics videos found everywhere on the web: animations, demonstrations, lectures, documentaries.
Please go here if you want to suggest other nice physics videos, and here if I mistakingly infringed your copyrights. If you understand French, you'll find a huge selection of physics videos in French in my other blog Vidéos de Physique.

Supernova Shock Waves—Powerhouses of the Galaxy

Yasunobu Uchiyama, a scientist with the Kavli Institute for Particle Astrophysics and Cosmology at SLAC, delivered the Nov. 27 SLAC Public Lecture, "Supernova Shock Waves: Powerhouses of the Galaxy."

Uchiyama's talk highlights the powerful remnants of exploding stars, called supernovae, which are among the universe's most spectacular pyrotechnics displays.

For thousands of years after a supernova explosion, massive orbs of high-energy particles with strong magnetic fields remain confined by the expanding shock wave. These remnants "are among the most beautiful and mysterious objects in the cosmos," notes Uchiyama, a member of the Fermi Gamma-ray Space Telescope Large Area Telescope collaboration who has expertise in supernova remnants.

The Fermi space telescope allows researchers to study supernova remnants in many wavelengths, from visible light to radio waves, X-rays and gamma rays. Uchiyama describes Fermi telescope observations that reveal how supernova remnants act as giant particle accelerators, spewing high-energy cosmic rays. Lecturer: Yasunobu Uchiyama, SLAC

Inverted Pendulum

A physical pendulum finds stability in its inverted position when driven at the proper frequency and amplitude combination.

The physical pendulum seen here is mounted on a ball-bearing pivot and can rotate 360 degrees; the pivot is driven at about 50 Hz with an amplitude of about 1 cm (3/4" per stroke) by a Sears Craftsman Auto Scroller Saw (model 315.172090); the length is 45 cm and the center of mass is slightly above 15 cm from the pivot; the rotational inertia is roughly 4x10^(-4) kg*m^2; the mass is about 100 grams.

X-ray Laser Captures Atoms and Molecules in Action

The Linac Coherent Light Source at SLAC is the world's most powerful X-ray laser. Just two years after turning on in 2009, breakthrough science is emerging from the LCLS at a rapid pace. A recent experiment used the X-rays to create and probe a 2-million-degree piece of matter in a controlled way for the first time—a significant leap toward understanding the extreme conditions found in the hearts of stars and giant planets, and a finding which could further guide research into nuclear fusion, the mechanism that powers the sun. Upcoming experiments will investigate the fundamental, atomic-scale processes behind such phenomena as superconductivity and magnetism, as well as peering into the molecular workings of photosynthesis in plants.

Jocelyn Bell Burnell: is the world going to end in 2012?

Professor Dame Jocelyn Bell Burnell is a visiting Astrophysics professor at the University of Oxford and now guest lectures on whether the world is going to end.

 This is in response to the Mayan calendar ending on 21 December 2012.

 She is famous for discovering the first radio pulsars and is one of the great minds in physics.


Cheers Physics (the physics of beer)

Physicist Rik Sargent meets Andy Moffat, a real ale brewer in North London with Redemption Brewing. They discuss the science involved in controlling the taste and colour of beer, focusing on the mashing of the grains and the temperatures involved in the brewing process.


Physicist Rik Sargent talks to Josh and Andy from Redemption Brewing who are experts in perfecting their real ale. They discuss how the sugar and alcohol affect the density of the beer and how to measure the ABV (alcohol by volume) in beer.


Physicist Rik Sargent chats to Andy from Redemption Brewing about why temperature is important in brewing a good beer. They also discuss hops and how they work efficiently by incorporating physics into their process.


Physicist Rik Sargent chats to Andy from Redemption Brewing about how the isinglass is used to clarify you beer towards the end of the brewing process.


 Physicist Rik Sargent chats to Andy from Redemption brewing about the physics behind keeping beer separate from oxygen in the air when moving it to a conditioning tank. Exposure to oxygen causes reactions in beer that lead to unwanted flavours. Therefore the physics of storing beer is paramount for keeping beer tasting its best.

Dark Energy

The universe is huge and getting bigger all the time, and we have we have dark energy - the most mysterious force in the universe - to blame/thank for it. Thought to make up more than 70% of the energy in the whole universe, Hank describes how dark energy was theorized to exist, and how scientists are trying to explain it.

From Kepler to Webb: The History of the Telescope

Hank regales us with the history of the telescope, and then introduces us to some folks from the team who are working on the newest telescope in the chronology - the James Webb Space Telescope, an infrared telescope due to launch in 2018. Thanks to the team at Northrop Grumman for allowing us the privilege of touring their facility, and to the scientists at NASA Goddard Space Flight Center for their help with this video.
