Some illustrations to my paper in The De Morgan Journal, Free Maths Schools”: some international parallels.
Mikhail Lavrentiev shows fluid mechanics experiments in a lecture for the Summer School: this rotating ring of smoke will fly across the lecture theatre without experiencing any detectable by eye resistance from the air.
The audience enthusiastically catches the rings. I am among of onlookers.
A staged publicity photograph. One of the boys is now a plasma physicist at the Columbia University.
And another one. The writing on the blackboard is taken from the mimeographed lecture notes of our physics course taught by Evgenii Bichenkov (the photographer asked us to write something frightening). The equations on the blackboard describe forced vibrations with damping, this is quite a canonical stuff in elementary mechanics. In the PhMSh parlance, it was called “колебалка с затухалкой”.
Evgenii Bichenkov invigilates an examination in physics.
I am present at all these photographs with the exception of the very first one.
