I found a new hobby… answering StackOverflow questions 🫠🥲

@martinmbauer I’ve been watching videos on Geometric Unity all day so this might do it:)

Which of your physics related opinions would get you in this position?

John von Neumann. Incredible how much one human can contribute…and how long a Wikipedia page can get. (this is in Chaos by James Gleik)

I just made my first ever pull request on an ML open source project:)

Today's progress: Integrating #topologicpy with @networkx_team

@lexfridman The Santa Fe Institute Complexity podcast had a panel discussion on this very topic. Included science journalist James Gleick, sci-fi author and SFI Miller Scholar Ted Chiang, and physicist and SFI Professor David Wolpert. It’s worth a listen! podcasts.apple.com/us/podcast/com…

The idea that time is an illusion breaks my brain. There are many weird ideas in physics, but that one... that, as Einstein said, "distinction between past, present & future is an illusion" is just too weird. The arrow of time seems fundamental to my cognition, but maybe not?
