4:02 PM  Alan Turing on Stage and Screen
It was a big week for Alan Turing dramatizations. On Monday, the UK and US trailers for the Turing biopic The Imitation Game, starring Benedict Cumberbatch, were released, and on Wednesday, the 102nd anniversary of Turing’s birth, the Pet Shop … Continue reading →

1:54 PM  Osculating the curve…
In the process of writing an article on curvature we got entirely distracted by making a geogebra worksheet showing the tangent, normal and osculating circle to any smooth function. The meaning and mathematics of all these terms is revealed in this article, but if you fancy getting your hands dirty yourself, have a play with the worksheet below. Please post your favourite function as a comment – the curvier and wigglier the better!

9:02 AM  Kissing the curve
Rachel Thomas
From a smile to a line drawing by Picasso, curves bring great beauty to our world. But how curvy is a curve?

10:24 AM  The Counterfeit Bill Problem
“I am often asked what the best way is to start the school year” writes Angela T. Barlow in the latest Teaching Children Mathematics blog. “My answer is always, ‘With a problem, of course!’ Not just any problem will do, though, as I want a problem that will spark discussion by eliciting a variety of solutions and/or solution strategies.” Math Tasks to Talk About

9:01 AM  Problems of gravity
Marianne Freiberger
Why (some) physicists want to modify Einstein's general theory of relativity.
Albert Einstein is an icon and for good reason. His general
theory of relativity, which describes the force of gravity, was an
intellectual tour de force. Not only were his ideas entirely new, they have also stood the test

4391 is a prime number. It is a Sophie Germain prime because 2 x 4391 + 1 = 8783 is also a prime.4391 is the smaller of two consecutive Sophie Germain primes with the same digital sum (A118506).4391 is the sum of the first 47 primes minus 47 (A101301).4391 is a number that cannot be written as a sum of three squares.4391 is 3332 in base 11 (A032811).Source: OEIS

La fonction de partition est souvent impossible à calculer. Le but de cet article est d'expliquer que, même si on ne peut pas la calculer explicitement, les mathématiques peuvent permettre par des arguments abstraits (la théorie des représentations) de dégager des propriétés de régularité sur la structure de la fonction de partition (par exemple qu'elle fait intervenir des polynômes). Une version plus détaillée et plus précise de ce texte est publiée simultanément dans la

L'observation de la nature ou des phénomènes sociaux nous offre de fascinants exemples de mouvements collectifs. Ces systèmes nonhiérarchisés sont capables de produire des structures ordonnées à grande échelle. Les mathématiques permettent aujourd'hui de mieux comprendre le lien entre comportements individuels et collectifs. Une version plus détaillée et plus précise de ce texte est publiée simultanément dans la Gazette des Mathématiens par la SMF.
