The Water Integrator (Russian: Гидравлический интегратор Gidravlicheskiy integrator) was an early analog computer built in the Soviet Union in 1936 by Vladimir Sergeevich Lukyanov. It functioned by careful manipulation of water through a room full of interconnected pipes and pumps. The water level in various chambers (with precision to fractions of a millimeter) represented stored numbers, and the rate of flow between them represented mathematical operations. This machine was capable of solving inhomogeneous differential equations.

- miketery 4y agoWhen I first started learning EE I conceptualized it with water. Ie voltage / potential is a higher water level vs else where. But this takes it to a whole new level, impressive!
- albrewer 4y agoWhat's funny is the math is identical between resistor - inductor - capacitor circuits, spring - mass - damper mechanical systems, and tank - pipe - valve fluid systems. The main difference between them is how you calculate the equivalent of resistance, inductance, and capacitance.
