There were many at Bell Labs and MIT who compared **Shannon**'s insight to Einstein's. Others found that comparison unfair - unfair to **Shannon**.

Use "entropy" and you can never lose a debate, von Neumann told **Shannon** - because no one really knows what "entropy" is.

Claude **Shannon**, the founder of information theory, invented a way to measure 'the amount of information' in a message without defining the word 'information' itself, nor even addressing the question of the meaning of the message.

From the vine-land, from the Rhine-land,From the **Shannon**, from the Scheldt,From the ancient homes of genius,From the sainted home of Celt,From Italy, from Hungary,All as brothers join and come,To the sinew-bracing bugle,And the foot-propelling drum;Too proud beneath the starry flag to die, and keep secureThe liberty they dreamed of by the Danube, Elbe, and Suir.

In fact, the science of thermodynamics began with an analysis, by the great engineer Sadi Carnot, of the problem of how to build the best and most efficient engine, and this constitutes one of the few famous cases in which engineering has contributed to fundamental physical theory. Another example that comes to mind is the more recent analysis of information theory by Claude **Shannon**. These two analyses, incidentally, turn out to be closely related.
