How to Build Turing’s Universal Machine

Modern computers wouldn't exist without the pioneering theories posited by Alan Turing, however the famed computer scientist was never quite able to make a working model of his hypothetical device. Turing's Cathedral by George Dyson follows Hungarian mathematician John von Neumann's efforts to build a computer based… » 3/15/12 11:00am 3/15/12 11:00am

The Internet of the Future Will Be Powered by Optical RAM

Fiber optics are the future of data transfer. The problem is that when that light signal reaches a machine, it must be converted into an electrical signal copper-veined devices can handle, resulting in speed bottlenecks. But Japanese engineers at NTT think their groundbreaking optical RAM will allow for an internet… » 2/27/12 4:20pm 2/27/12 4:20pm
