There is an interesting story hidden in the history of technology, do you know that 90 years ago a computer was made which worked on water. It was long before silicon chips or electronic transistors when a Soviet scientist named Vladimir Lukyanov created a computer running on water. Many people might be wondering where this computer built in 1936 is today, so let us tell you that today this system is lying in a museum in Moscow.

For what purpose was the water computer created?

A complex network of interconnected glass tubes and valves was used in this computer. This system could solve complex calculus and differential equations by adjusting the water level.

Vladimir Lukyanov created something in 1936 that surprises everyone today, but by using water he created a computer that solved partial differential equations. In pictures of the Lukyanov computer, you'll see a complex system of interconnected tubes filled with water. The flow of water was changed by adjusting taps and plugs, while the end result was seen by measuring the water level in certain tubes. It was also called a water integrator and was originally designed to solve the problem of cracks in concrete.

Where is this computer now?

This computer made by a Russian scientist in 1936 was quite unique and today everyone wants to know where this computer is today? If you also want to see this unique and antique computer system, then let us tell you that this system is now kept in the Polytechnic Museum of Moscow.
