Behind the scenes video is here: https://youtu.be/L_pWPM8T-kc Get it from Maths Gear and be guaranteed a signed first edition hard back. https://mathsgear.co.uk/products/humble-pi But it is also available on Amazon. https://www.amazon.co.uk/Humble-Pi-Comedy-Maths-Errors/dp/0241360234/ref=sr_1_1?_encoding=UTF8&tag=stanupmath-21 For teachers (or anyone who would like some extra maths to do!) we have made an activity sheet about infinite series which give pi. https://www.think-maths.co.uk/pi-sums Celebrate Pi Day this 14 March (the date is written 3.14 in some countries; good enough for me!). Check out the fantastic chalkdust magazine: http://chalkdustmagazine.com CORRECTIONS - I’m not worrying about the bending of the beam bringing the forces slightly closer to the turning point. Just getting in before anyone brings it up. - People are upset I said torque instead of moment. I’m sorry. - People are upset I said “one over a fourth” instead of “one over four”. Technically I was wrong. But am TOTALLY NOT SORRY. - Let me know if you spot anything! Thanks to my Patreon supports who do support these videos and make them possible.
