Welcome


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.

Supercomputing Sheds Light on the Dark Universe

At Argonne National Laboratory, scientists are using supercomputers to shed light on one of the great mysteries in science today, the Dark Universe. With Mira, a petascale supercomputer at the Argonne Leadership Computing Facility, a team led by physicists Salman Habib and Katrin Heitmann will run the largest, most complex simulation of the universe ever attempted.

By contrasting the results from Mira with state-of-the-art telescope surveys, the scientists hope to gain new insights into the distribution of matter in the universe, advancing future investigations of dark energy and dark matter into a new realm.

The team's research was named a finalist for the 2012 Gordon Bell Prize, an award recognizing outstanding achievement in high-performance computing.

 

Frozen Powder Drops

When water droplets impact super hydrophobic powder at a high enough velocity, they "freeze" into place. The powder fully encapsulates the droplet, forming shapes resembling bowling pins, ice cream cones, and more.

This video is a submission to the American Physical Society's Division of Fluid Dynamics Gallery of Motion for 2012.

ALPHA-2 arrives at CERN

While many experiments are methodically planning for intense works over the long shutdown, there is one experiment that is already working at full steam: ALPHA-2. Its final components arrived last month and will completely replace the previous ALPHA set-up.

Unlike its predecessor, this next generation experiment has been specifically designed to measure the properties of antimatter.

Quarks and gluons with an unsung hero: Professor Graham Ross

Professor Graham Ross from the University of Oxford, winner of the 2012 Dirac Medal awarded by the Institute of Physics for his work in developing the standard model of particles and forces that has led to many new insights into the origins and nature of the universe. A powerhouse of physics, and one of the UK's best kept secrets, Graham laid out the pathway to the discovery of the gluon, the force carrier for the strong nuclear force, and taught Richard Feynman how quantum chromodynamics could be used to work out the interactions between quarks and gluons.
