And the next Glasgow MathsJam also takes place tonight (21 Oct) from 7pm at the Esquire House, Great Western Road. If you enjoy some friendly maths fun over a drink, it might be just the thing for you. www.mathsjam.com/cities/glasgow #MathsJam #STEM #Glasgow #MathsToday #UKMathsChat

The next Edinburgh Maths Jam takes place tonight (21 Oct) from 7pm at the Brass Monkey on Drummond Street. If you enjoy some friendly maths fun over a pint, or other beverage, it might be just the thing for you. www.mathsjam.com/cities/edinburgh #MathsJam #STEM #Edinburgh #MathsToday #UKMathsChat

It's almost the end of this year's gathering. Our final session of talks featured Adam Townsend, who showed us how we can use differential equations to make beautiful moving patterns - you can explore them yourselves at https://visualpde.com. We also heard from Hannah Gray, who was inspired by playing http://heardledecades.com to talk about whether men sing more songs (spoiler alert: yes, but it's better now than it was in the 1950s!) Last but absolutely not least, Colin Wright talked about the twist of a Moebius Rollercoaster: https://en.wikipedia.org/wiki/Grand_National_(roller_coaster) #mathsjam #maths #differentialequations #movingpatterns #skittles #uniqueness #moebius #rollercoasters #music #domensingmore

In this session, Alex Arthur (@JamesA) shared an odd fountain they found whilst travelling that is both mathsy and artsy. @Tony_Mann showed us a magic square, which is interesting whichever way you look at it: https://www.markfarrar.co.uk/chris-wardles-reflections-magic-square.htm. We revisited (a kind of) slide rule with @gavan Fantom, who told us about Mechanical Flight Computers. We then heard from @pozorvlak about lathes, and cool shapes that can be produced using them (including a https://en.wikipedia.org/wiki/Hypotrochoid) Vanessa Madu talked about modelling an ocean and the commendable properties of rubber ducks for this: https://en.wikipedia.org/wiki/Friendly_Floatees_spill. Following this, Joey Marianer spoke on the Prisoner's Dilemma and intuition (see https://www.lesswrong.com/posts/HFyWNBnDNEDsDNLrZ/the-true-prisoner-s-dilemma for more info). @andrewt then spoke about a graphics trick used in old videogames to rotate sprites - just do three shears! #mathsjam #maths #fountain #strasbourg #magicsquares #sliderule #flightcomputer #modelling #rubberducks #ocean #prisonersdilemma #graphics #videogames #shears #imagerotation

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

In our second session of the day, we heard from Jørn Hafver who trained an AI in audio recognition right in front of us - so it could tell how loud we were clapping at the end. Ben Ashforth spoke about a journey he went on, inspired by a talk from the last gathering, to visit roads named after every day of the year (details at http://benguin.co.uk/roads). @alisonkiddle talked about the maths behind the games Guess Who and Which One Doesn't Belong, and has a pleasing binary chop device made from card with pins and holes. Phil Ramsen followed up on his talk from three years ago and discussed slide rules and Kolmogorov. Daniel Johnson explored the possibly surprising link between Numberblocks and Polyominoes (https://youtu.be/htnZGHjX8p4?si=YzAXxPP7lT2-_Do5&t=522)- and @Tarim said what we've all been thinking and pointed out some illogical song lyrics - lions don't really live in the mighty jungle, and Kilimanjaro is nowhere near the Serengeti! #mathsjam #maths #ai #travelling #guesswho #wwdb #sliderules #means #averaging #kolmogorov #numberblocks #polyominoes #songs #logic #lyrics

Hi folks,

Just a quick reminder that August's #Bletchley & #MK #MathsJam is:

- *tomorrow*: Tuesday 22nd!
- at Brewhouse and Kitchen in Central Milton Keynes (close to the theatre, *not* to be mixed up with the Midsummer Tap which is very close and has "pub and kitchen" on the sign!).
- From 7pm

Bringing yourself is an absolute must, and any #mathematical #ideas, #conundrums, #puzzles, #tidbits, #games, #books, #toys or #tales are encouraged but completely optional.

If you're able to let me know if you're intending to come I'd appreciate it, otherwise just turn up. If you have any questions please don't hesitate to ask.

See you there,

Tom

@ColinTheMathmo @VisualStuart Sorry for the poor quality of introduction - I was on my phone (my laptop, I'm still recovering from a ransomware).
Summarising:
I met Colin at college, where he corrected many of my initial bad juggling habits, and introduced me to the (then, very new!) concept that became known as #Siteswap. I keep up with him for the #recreationalmaths , the #MathsJam events, and other reminders that I used to be, and still am, interested in that space.
Stuart, on the other hand, is someone who seems to show up in random unconnected places - we were both Microsoft MVPs at various times, and with the #PortlandJuggling Festival being the most local, reliable annual juggling festival, I've run into him a few times there. For the first couple of years, there was definitely a vibe of "I've seen you before, but I can't remember where".
There is likely to be a #SeattleJuggling event in the next year.
Hopefully that's enough hashtags.
