This week, PopSci is peeking under the hood of some of the nation's biggest and baddest supercomputers--the machines that turn big data into big discoveries, big technologies, and big leaps forward. Over the last week, we managed to get each of the busy machines in this series on the phone to see what they were up to on during a particular day. They were happy to share.
Today we chat with the 63 thousand processing cores of the University of Texas's Ranger.
Five amazing, clean technologies that will set us free, in this month's energy-focused issue. Also: how to build a better bomb detector, the robotic toys that are raising your children, a human catapult, the world's smallest arcade, and much more.
