Communication Theory

Communication Theory was born in 1948 with the publication of an article titled A Mathematical Theory of Communication authored by Claude Shannon while working at Bell Labs. Communications theory is a highly mathematical subject, but has very practical applications.

In simple terms, Communication Theory says it is possible send information through a noisy connection or channel essentially without error as long as the information is not sent too quickly. This is a decidedly counterintuitive notion with sweeping repercussions. Consider sending a recorded video image from deep space back to the Earth. Communication Theory tantalizes you with the possibility there is a way to get a perfect copy of what was recorded even if the signal is corrupted by noise along the way.
