Guy builds digital computers using strings, weights, and a chessboard

Sploid referee Kimberly Nguyen has spotted this really neat video demonstrating how computer logic Bill Gates work using just strings and weights . “ I ’m an Electrical Engineering / Computer Engineering John R. Major and I ’ve never encounter anything like this before ! ” Me neither . It ’s really clever .

The meat of digital calculation is the habit of continuous physical states to be a discrete telephone number of symbols and the ability to perform system of logic based on those symbol . Although electronic circuit are exceptionally well - suit for this , any system that can address symbols as both input and output is a digital computer . Here , I ’ve demonstrated the construction of dewy-eyed digital computers ( specifically , binary logic gate ) using pulley-block and weights .
