Kicking us off on our first session of the morning was Matt Parker @standupmaths who shared how he's planning to break the world record for the most digits of π calculated by hand, for next π day (see his other attempts here: https://www.youtube.com/playlist?list=PLhtC92GarkjyYbxI3-4qzIWIRbZaw4wuP). We also heard from Bob Huxley, who has also been thinking about π day, but this time on Mars where it turns out it's actually tomorrow! Annette Margolis then talked about her class' favourite (and least favourite) way to solve quadratic equations. John Hoskinson discussed Diffy Squares (https://mathforlove.com/2020/03/diffy-squares/) and adapted them to generalised diffy N-gons - for odd N, you get repeating cycles! Nobody has ever said the word 'diffy' more times in the space of 5 minutes. Alistair Bird @outofthenorm shared about a mathematician who got inspired in the bath (but not that one), and what his discovery meant (turns out, not much, but it did inspire some nice results around Fermat's Last Theorem). Read more here: https://outofthenormmaths.wordpress.com/2011/11/09/blitz-krieger/ Adam Atkinson talked about Misère Games, leading to his discovery of just how many semigroups of order 8 there are, inducting us all into membership of DOCTIAL (the Department of 'Crikey! That Is A Lot!'); and finally Harlan Connor got LOUD about signal processing - it's possible to have peaks in audio volume that are higher than the maximum value the system can store! #mathsjam #maths #pi #worldrecords #mars #piday #quadraticequations #classwork #teaching #diffysquares #baths #inspiration #misèregames #doctial #loud #signalprocessing #groups #monoids #semigroups #combinatorialgametheory

Why is pi approximately equal to the square root of g (g = 9.8 N/kg)? It's not a coincidence. #piday

Apparently, some people celebrate #PiDay by measuring pi with random objects. This was news to me when I stumbled across a fantastic post by Jim Hall, who measured pi using a #RaspberryPi 3 Model B, some graph paper, and a pencil.

@ozdreaming @Raspberry_Pi yay! That's the the spirit of #PiDay! I highly recommend picking one up (or the HQ might work for you?); I've barely scratched the surface of what it can do — next I'm going to dive into the machine learning side of things! 🥧💗

Evening celebration of #piday . Curious that I've had coconut cream pie a lot on this date. I'm not partial to that many kinds of pie, and I guess this has been what's available.

They were all out of "little" pies by the time I got to The Duchess this afternoon. Bought this darling tart for my darling husband instead. And there was much rejoicing. #Pi #PiDay #Edmonton #yeg #yegfood #124thStreet https://duchessbakeshop.com/collections/pastries/products/tart-josephine

Happy Pi Day! I made Arabic meat pies for supper, followed by wild berry pie for dessert. All pies are very approximately round, as befitting a circular celebration.

Happy 3/14 - #PiDay! Appropriately, let's recognize the House of Pies in #LosFeliz, the local survivor of a national chain started in 1969 by Al Lapin, Jr (who also founded IHOP). The chain was downsized in 1976 leaving the Vermont Ave location & a few in Houston, TX. 🥧

This #PiDay, we were inspired to run espeak for a greeting. We hope you enjoy, and we hope you will attend #LibrePlanet to see how one father is introducing #SoftwareFreedom to his son via the command line. More info: https://libreplanet.org/2023/speakers/#6142

A terminal, then a prompt for: espeak "Happy Pi Day, everyone, and hurrah for programs like espeak, licensed under a free, copyleft license like GPLv3 or later!"

On the one hand, #PiDay is a quirk of the clearly incorrect and stupid US date format. On the other hand, it is an excuse to make pie.

Things that absolutely count as pie: Tarts, quiche, flan, pizza.

Things that you can make a good case for being pie: Cheesecake, empanadas, pasties, calzones.

Things that are absolutely not pie: Brownies, muffins.

No, brownies are not pie even if you bake them in a pie tin.

Yes, somebody tried to argue this meant they counted.

@awoodsnet The thing about eating pie to celebrate Pi Day is that the formula for finding the area of a circle is Pi multiplied by the radius (R) squared. It's usually read as "Pi R squared."

But everyone knows pies are round!

Ah, except for pizza. Sicilian style pies are square (or rectangular).

@mikaylamic The same has happened to me.

Some years ago I had a temp job in the math department of a large university. On #PiDay I stopped at the Greenmarket and bought two pi(e)s, then sent an e-mail to the team* I was working with to say that pi(e) would be served in the conference room at 1:59. They were puzzled, then amused--then wondered why no one else had thought to do this.

* It was a temp job. I couldn't afford enough pi(e)s for the entire 13 story building.

I only use metric angles. A circle is 1 metric angle. What you call "1⋅π⋅r" in the imperial system is simply 5 deciangles. It's way more logical. #piday

Happy Pi(e) Day nerds!

You know what’s great about pizza, and pie in general?! Of course it’s delicious, but it’s also a chart that updates in real time, that shows you how much is left

May you all partake of some pie today 🥧😄 #pi #piday

14/3 = 4.66666666667
22/7 = 3.14285714286

Neither's right, but one's much closer than the other.

(Oh, and 3/14 = 0.21428571428 which is waaaaaay off).
