Happy Pi-day (even though I prefer Tau) everyone! 🤪
This year @3blue1brown made another beautiful YouTube video about how pi can be calculated with two frictionless sliding blocks bouncing off each other with perfect elastic collisions.
Enjoy! 🥧
And of course @standupmaths had to do the Pi collisions experiment in the real world the imperfect way together with #SteveMould, who also gave Tau some much needed love. 😁
