Astonishing Tech Facts to Blow your Mind
Russia Had Built a Computer That Ran On Water
In the days before Intel, Apple and Google, computing was a much more traditional affair. We're talking levers, gears, and other mechanisms that could all automate counting in some way or other. Russian scientist Vladimir Lukyanov, however, built one that ran on water. Built in 1936, it was the world's first computer for solving partial differential equations, a fundamental problem that anybody who did math, physics or engineering at college will testify that it was lot more difficult to solve by hand.
To solve the differential equations, Lukyanov fiddled around with a series of interconnected, water-filled glass tubes. The levels in certain tubes gave the answers, while adjusting taps and plugs changed the variables.
