If your New Year's resolution is to be more organized and orderly, maybe you should take a cue from the universe. With planets, stars, and galaxies, the cosmos is surprisingly orderly—or in physics parlance, in a state of low entropy. At the time of the Big Bang, the universe had even less entropy. Sean Carroll, a theoretical physicist at Caltech, will examine this mystery at next week's TEDxCaltech. In separate talks, Caltech physicists Kip Thorne and John Preskill will also discuss Richard Feynman's legacy.
