Heat as a villain for miniaturization-A demonstration!!

The microprocessor is a complex machine, made from millions of tiny switches called transistors. Over time we’ve been able to reduce the scale of these microprocessors, fitting billions of transistors onto a space the size of a postage stamp. This has also allowed us to not only reduce the production cost of these units, but more importantly increase their speed – paving the way for the computer revolution. As a result, the exponential rise in computing power in the last 30 years has been staggering.

In his first Christmas Lecture 2008, Chris Bishop explains the challenges that are making it harder to continue the incredible improvement in speed
