This evening I was reading an article about quantum gravity (because of course that’s the sort of thing I do) and there was a photo of the researcher at the chalkboard:
As soon as I saw this, I thought, nobody does that. I can’t honestly believe advanced research into spacetime and gravitons actually involves someone writing on a chalkboard with multiple colors of chalk. How… primitive. I’d expect they’d use at least pen and paper, but more likely computers.
That said, a photo in the article of a guy sitting in front of a computer wouldn’t be very interesting, so they probably asked him to write a bunch of equations on the board and pose in front of it…
