OK Matt, what have you got?
π, Phase Space, and Bouncing Billiard Balls
There are many ways to estimate or calculate π, that number that is irrational, but well-rounded. But perhaps none is as remarkable as that outlined in a 2013 paper by G. Galperin. In this brief article we’ll have a look at the problem, and see the setting, although we’ll leave the interested reader to hunt…
π and The Simpsons
In “The Simpsons and Their Mathematical Secrets”, I documented all the mathematical references hidden in the world’s favourite TV show. Look carefully at various episodes, you will spot everything from Fermat’s last theorem to the Riemann hypothesis, from the P v NP conjecture to Zorn’s lemma. All these references are embedded in the show, because…
Alex Bellos’s π Day blog post
For a blog, I write sentences. Of Pilish words. It’s truly difficul.
Cédric Villani’s Birth of a Theorem is Radio 4 Book of the Week
Birth of a Theorem, the autobiographical book by French mathematician and (spoiler) Fields Medallist Cédric Villani, is Book of the Week on BBC Radio 4 this week, read by non-French non-mathematician Julian Rhind-Tutt. Villani also appeared on discussion show Start the Week on Monday, talking about ‘the mathematical mind’ along with mathematician Vicky Neale; Morgan…
How Ultimate is Ultimate π day?
This year, π day will be celebrated, as always, on 14th March. Unlike most years, π day will be more accurate than usual – owing to the fact that the year, 2015, will give the date 3/14/15 (provided you’re using a US calendar date format) – and for this reason, some people are calling it…
Mandelbrot’s bum is full of π
They say that $\pi$ is everywhere. (They say that about $\phi$ too, but I’m not buying it.) I thought it would be interesting to discuss the most unexpected place I’m aware it’s ever appeared.
