Gregorio Ricci-Curbastro died #OTD in 1925.

He is most famous as the discoverer of tensor calculus which then became the "lingua franca" of the subsequent theory of Albert Einstein's general relativity, as is shown in a letter written by Albert Einstein to Ricci-Curbastro's nephew. via nostr:npub1kvnpp3m60derhwpqwc09zhk3ehk48tr6agc6dk9z2vggu9sga28qpxhm73
