Our ability to transform information – phone calls, music, video, virtually everything – into digital bits of data and to transmit billions of them per second is founded upon the innovative work of Bell Labs and MIT mathematician, Claude Shannon (1916-2001). – – – Claude Shannon's extraordinary idea – that basic principles of binary or digital information can be related to fundamental physical laws – was instrumental in shaping our digital era. Today, Shannon’s theory remains the guiding foundation for communication scientists and engineers in their ongoing quest for faster, more energy efficient, and more robust communication systems.
