The Coldest Object In The Universe Has Been Created In An Italian Lab

For a period of 15 days, a cooled copper mass enclosed in a cryostat container may very well have been the coldest object in the Universe. At -273.144 degrees Celsius, it nearly achieved absolute zero. The technique, which resulted a world record, could produce important new insights into exotic particle physics. » 10/22/14 12:40pm 10/22/14 12:40pm

See Neal Stephenson's Badassery As He Opens A Bottle With A Sword

Sabering, or sabrage, is a champagne-opening art popularized at the time of Napoleon's military campaigns. In this video, Neal Stephenson, the author who gave us Snow Crash and Cryptonomicon, shows that doing it properly requires not blunt force, but elegance, precision and a knowledge of physics. » 10/15/14 9:20am 10/15/14 9:20am

A Brief History of Scientists Hunting for Time Travelers

Time travel is possible—or at least a lot of serious physicists say so. It's probably not possible to pull it off in a souped-up Delorean, but there are wormholes, Tipler cylinders, and other Einstein-inspired theories for how it could work. Which raises the question: Why haven't we met any visitors from another time? » 10/09/14 3:39pm 10/09/14 3:39pm
