Logic of Analog & Digital Machines

Scientists from different fields are searching for the appropriate definition of what is digital and analogue, but the profile of the technologies that have changed mankind's lifestyle and the history of the world still resist the scrutiny of thinkers. Rocchi, a brilliant scientist of IBM, claims that understanding analogue versus digital is not as easy as comparing the adjectives digital/continuous or natural/artificial. He suggests a new key to interpret the digital and the analogue machines and conducts an accurate analysis of the systems' core.
