Teaching
Zavoisky was a popular teacher who focused on demonstrations rather than theories. He himself showed various cryogenic phenomena, such as hardening and shattering of matter upon freezing. One experiment nearly resulted in his arrest by the internal police. Zavoisky demonstrated interference of polarized light in a biaxial crystal that resulted in an encircled swastika-like image projected onto the screen in front of a large audience. The demonstration crystals were soon confiscated and analyzed by a special commission, seeking relation between the experiment and Nazi Germany, and only a series of letters from scientists settled the matter.

Of clowning; helping the old, too, as they ought.”
