A posthumous Paul Erdős signature

I was back in the Numberphile "archive" yesterday sorting through old brown papers... and I came across this one.

It is from a video with the late Ron Graham in which we discussed his close relationship with Paul Erdős.

Graham handled all paperwork and finances for the eccentric Erdős... and also signed his name quite often.

On this paper from 2014, Graham signed it as Erdős too.

Erdős had died in 1996. Graham died in 2020.

Cheat Notes from Pi Video

I hope you saw our latest video (well, three videos) all about the new formula for Pi.

Tony Padilla is always very well prepared and makes notes (on his iPad) for a filming session... We jokingly call them "cheat notes" which he hides off camera.

Here are Tony's notes from our latest video, shared with permission.
