Hi! I'm a maths student at Helsinki University. For the past year or so I've been writing a popular (not as in visitors) maths blog, www.nollakohta.fi, in Finnish. In addition to human languages (FIN/ENG/SWE/FRE) I respond to quite a few computer ones (esp. C#).
Interested in seeing if toots > tweets!
A little spoilery: the book indeed suggests ways to not be wrong using mathematical lenses, but cleverly doesn't promise "ways to be right" 😉
I quite liked @ColinTheMathmo’s entry to #BigMathOff: a simple, initially counterintuitive result that becomes intuitively obvious after a quick think! I wonder how many totally different ways there are to prove it.
If you haven’t yet, go read about it and beautiful Penrose tilings: http://aperiodical.com/2018/07/the-big-internet-math-off-round-1-edmund-harriss-v-colin-wright/
So, how many of you call the # symbol the hashtag in all contexts, like you would call . period or dot or you @ the at?
I'm running a four-round instant knock-out tournament throughout the month of July to basically squeeze a load of fun maths out of my friends. Let's see if we can make it all come together! Voting starts on the 1st of July.
I’ve now updated the original post with a solution. Hoping that we found the same one!
being an applied mathematician means praying to every religious figure that your code converges
When designing a user interface, imagine some old woman using it, say Margaret Hamilton, and she's clicking your app's buttons and saying to you, as old people do,
"Young whippersnapper, when I was your age, I sent 24 people to the ACTUAL MOON with my software in 4K of RAM and here I am clicking your button and it takes ten seconds to load a 50 megabyte video ad and then it crashes
I'm not even ANGRY with you, I'm just disappointed."
It is also very humbling to work in a team of so many PhD’s. My interpretation of ”fun algorithm work” is pretty lame compared to what they do! Still, very encouraging to see how much I already can do.

Here's a nice description by Math3ma of the Assassin Puzzle as described by Mirzakhani, and a solution for the square case: http://www.math3ma.com/mathema/2018/5/17/is-the-square-a-secure-polygon . I had a lot of fun today trying to work it out for myself, then trying to check it for an equilateral triangle, then for a regular hexagon. The equilateral triangle seems to be pretty well-behaved, but the hexagon has been very interesting, and I haven't quite worked out whether it's secure, yet. :)

Just had the last exam of the year, and the sky’s not too bad either. I approve!
Recently I discovered a surprising fact about numbers, so I made an online web thing to give it the recognition it deserves. Give it a go: http://somethingorotherwhatever.com/sum-of-3-palindromes/
