Using an Out-of-Control Car to Calculate π.

From Standup Mathematician.

Happy Pi Day: 14 March 2023. (Yes, the video goes out a few days early. So teachers have time to plan their Pi Day activities.)

Huge thanks to Eric and the whole team for letting us in to skid some cars and calculate pi.

It was an active and working site and they did a great job making time, staff and cars available for us.

If you want to learn more about traffic reconstruction calculations, check out this (slightly odd) 1983 book "Handbook For The Accident Reconstructionist".

Huge thanks to my Patreon people who support all my silly Pi Day videos with their irrational funding. Join in and we’ll make Pi Day 2024 bigger and sillier.

And sorry I could only put the names of Statistically Significant and higher Patreon tiers on the scrolling credits. A bunch of that was done by hand and that was the limit of what could be lined up.

– If we had used 26/38 exactly were would have π = 3.136421 which is basically 3.14 (First spotted by CK.)
– Let me know if you spot anything else!
