The Wilhelm Scream is Back

The Wilhelm Scream, named after Private Wilhelm, a character in the 1953 Western film The Charge at Feather River, has appeared in over 140 Hollywood films, including Star Wars, Raiders of the Lost Ark, Reservoir Dogs, and others. (See full list here.) Now the scream is coming back. According to the LA Times, the scream will again echo through cinemas with the May 7 release of Jon Favreau's Iron Man 2. Above, you can watch a montage of The Wilhelm Scream. Naturally, the ur-scream comes first. Thanks Veronica for the tip on this one!

The Essential Kurosawa

Akira Kurosawa, the great Japanese director, would have turned 100 today. And to mark the occasion, The Guardian has assembled a handy guide to ten key Kurosawa movies. Above, we highlight a clip from Seven Samurai (1954), an enormously influential film both in Japan and abroad. The Guardian guide celebrates this and nine other major Kurosawa films, so it's definitely worth a visit. Meanwhile, you'll conveniently find two important Kurosawa works (Rashomon and Throne of Blood) listed in our collection of Free Online Movies.

A great find by Maria Popova aka @brainpicker

For a Tiny Instant, Physicists Broke a Law of Nature

An intriguing bit of news from the Yale Bulletin. It begins:

For a brief instant, it appears, scientists at Brook haven National Laboratory on Long Island recently discovered a law of nature had been broken.

Action still resulted in an equal and opposite reaction, gravity kept the Earth circling the Sun, and conservation of energy remained intact. But for the tiniest fraction of a second at the Relativistic Heavy Ion Collider (RHIC), physicists created a symmetry-breaking bubble of space where parity no longer existed.

Nature by Numbers: Short Film Captures the Geometrical & Mathematical Formulas That Reveal Themselves in Nature

For centuries, artists and architects have used some well-known geometrical and mathematical formulas to guide their work: The Fibonacci Series and Spiral, The Golden and Angle Ratios, The Delauney Triangulation and Voronoi Tessellations, etc. These formulas have a reality beyond the minds of mathematicians. They present themselves in nature, and that's what a Spanish filmmaker, Cristóbal Vila, wanted to capture with this short film, Nature by Numbers. You can learn more about the movie at the filmmaker's web site, and also find his latest film here: Inspirations: A Short Film Celebrating the Mathematical Art of M.C. Escher.
