Apart from formulas and text, scientific works can often have “figures” as well. Note that modern computer graphics owes much of its origin to scientific and engineering graphics, since the first computers were developed for scientific, industrial, and military purposes.

There are lots of computer programs for producing drawings and diagrams. But how were plots and figures drawn in the middle of the last century? By hand, with the aid of a drawing board, a drawing pen, drawing curves, a T-square rule and other tools, in pencil or ink.

Of course, no tools like this are found in the Museum-Study of Bruno Pontecorvo, but there are well-done drawings on transparent paper. Perhaps, they were used at lectures and presentations or attached to a manuscript.nDelight in them together with us!
