This is What Happens When You Run Water Through a 24hz Sine Wave
What!? How is this even possible? Because science, my friends. Brusspup’s (previously) latest video explores what happens when a stream of water is exposed to an audio speaker producing a loud 24hz sine wave. Run the rubber hose down past the speaker so that the hose touches the speaker. Brusspup did a similar experiment last year where it looked as if the water was flowing in reverse.

Exactly 1week to "Space Race - Yuri's Night 2014: Hunting Comets!" team challenge on BoincStats Hello everyone, in exactly one week the "Space Race - Yuri's Night 2014: Hunting Comets!" team challenge on BoincStats will start. There are already 14 teams in for for the Yuri's Night challenge and we hope to see more of you participating there. This is our annual team challenge to honor Yuri Gagarin, first human in space, and our own birthday. Comet Trails: An IMEX application for predicting meteor storms at spacecraft or planets AerospaceResearch.net is happy to announce the next application running on the Constellation platform, the "IMEX Cometary trails". Description: The "IMEX Comet trails" project is an ESA-funded project run at the Institute of Space Systems (IRS) at the University of Stuttgart to characterize dust trails produced by comets in the inner solar system.

"Twistor" Theory Reignites the Latest Superstring Revolution: Sc
In the late 1960s the renowned University of Oxford physicist and mathematician Roger Penrose came up with a radically new way to develop a unified theory of physics. Instead of seeking to explain how particles move and interact within space and time, he proposed that space and time themselves are secondary constructs that emerge out of a deeper level of reality. But his so-called twistor theory never caught on, and conceptual problems stymied its few proponents. Like so many other attempts to unify physics, twistors were left for dead. In October 2003 Penrose dropped by the Institute for Advanced Study in Princeton, N.J., to visit Edward Witten, the doyen of today’s leading approach to unification, string theory. Expecting Witten to chastise him for having criticized string theory as a fad, Penrose was surprised to find that Witten wanted to talk about his forgotten brainchild. Penrose’s original goal was to reconsider how quantum principles apply to space and time.

Physics Flash Animations
We have been increasingly using Flash animations for illustrating Physics content. This page provides access to those animations which may be of general interest. The animations will appear in a separate window. The animations are sorted by category, and the file size of each animation is included in the listing. In addition, I have prepared a small tutorial in using Flash to do Physics animations. LInks to versions of these animations in other languages, other links, and license information appear towards the bottom of this page. The Animations There are 99 animations listed below. Other Languages and Links These animations have been translated into Catalan, Spanish and Basque: En aquest enllaç podeu trobar la versió al català de les animacions Flash de Física. Many animations have been translated into Greek by Vangelis Koltsakis. Most animations have been translated into Hungarian by Sandor Nagy, Eötvös Loránd University.
