This computer was built to solve partial differential equations.

It was particularly useful in calculations for concrete construction, allowing for different materials and climate conditions.

Initially, Lukyanov developed the Water Integrator to address the problem of cracking in concrete under different environmental conditions.

This ingenious system offered practical solutions to manage the diverse materials and extreme climatic conditions faced in Russia.

Today, the Water Integrator can be seen at Moscow’s Polytechnic Museum.
