Are you a fan of computer science? Want to see something cool? Then you should watch the video below, where a very bright young lad by name of Alex Gorischeck makes a digital computer with nothing more than some string, some weights, and a chessboard:
Pulley Logic Gates from Alex Gorischek on Vimeo.
Every digital computer is, essentially, a very complex system of various pulleys and strings. According to the video, a digital computer is categorized by “the use of continuous physical states to represent a discrete number of symbols, and the ability to perform logic based on those symbols.” In other words, any system that can interpret and perform input and output symbols is a digital computer.
Gorischeck’s video demonstrates this principle through the creation of binary computer logic gates through strings and weights on a chessboard. What’s more, he shows you how easy such a system is to create.
And people say computers are difficult to manage. Looking at this video, it’s amazing how many things we’ve managed to accomplish using a machine that’s basically just pulleys and strings. Score for humanity.
