These days, supercomputers are everywhere—and they really don't need much space at all. Have an Xbox One posted up in your living room? That's a supercomputer. A laptop-tablet hybrid in your bag? That's a supercomputer, too. (Don't even get us started on the thing in your pocket…) But when supercomputers first came around, they needed much, much more space. 

Just take a look at the world's first one: The Electronic Numerical Integrator and Computer (ENIAC). Originally built at the University of Pennsylvania's School of Engineering, in 1946, ENIAC weighed 60,000 pounds and took up a room larger than most studio apartments (1,500 square feet). Shortly after construction, ENIAC was sent off to the military, where it was used to calculate ballistic trajectories (translation: launch missiles) with frightening accuracy. Today, computer experts at Penn credit ENIAC with heralding in the "dawn of the information age."
