A black and white photo of Enrico Fermi standing at a blackboard, explaining a scattering problem. He is wearing a charcoal wool three-piece suit, with a striped tie and a light-colored shirt. Fermi is looking to the right of the photographer, smiling at someone in the audience.

Enrico Fermi, one of the foremost physicists of the 20th century, was born #OTD in 1901. While most physicists focus on either experiment or theory, Fermi excelled at both.

Now, estimate how many new physicists will be born today. πŸ§ͺ βš›οΈ 🎒 (1/n)
