Entropy (Information Theory) | Brilliant Math & Science Wiki

In information theory, the major goal is for one person (a transmitter) to convey some message (over a channel) to another person (the receiver). To do so, the transmitter sends a series (possibly just one) partial messages that give clues towards the original message. The information content of one of these partial messages is a measure of how much
