The report of B. M. Hessen at the I All-Union Congress of physicists. The Congress was held in Odessa from 19 to 24 August 1930. At the plenary meeting B. M. Hessen, made a report on methodological issues of quantum physics, the relationship of physics and philosophy. Mechanistic materialism in his time came to replace the scholastic physics.

Hessen believed that the development of (...) the basic concepts of natural science (matter, space and time, motion, wave and particle, pattern and randomness) coincides with the approach of dialectical materialism.
