Eccentric French maths genius's 'scribblings' go online

Nearly 18,000 pages of notes by eccentric French maths genius Alexandre Grothendieck were posted online Wednesday by his alma mater, Montpellier University in southern France.

Grothendieck, who died aged 86 in 2014, "revolutionised an entire area of mathematics, algebraic geometry," said Jean-Michel Marin, head of an institute that bears the mathematician's name at the university.

Math Champion Wins With Answer About Pecking Chicks

A 13-year-old boy from Texas won a national math competition on Monday with an answer rooted in probabilities — and a dash of farming.

The boy, Luke Robitaille, took less than a second to buzz in at the Raytheon Mathcounts National Competition with the correct answer.

The question: In a barn, 100 chicks sit peacefully in a circle. Suddenly, each chick randomly pecks the chick immediately to its left or right. What is the expected number of unpecked chicks?

New Twist on Sofa Problem that Stumped Mathematicians and Furniture Movers

The Moving Sofa problem asks, what is the largest shape that can move around a right-angled turn? UC Davis mathematician Dan Romik has extended this problem to a hallway with two turns, and shows that a 'bikini top' shaped sofa is the largest so far found that can move down such a hallway.

French Mathematician Yves Meyer Wins Top Prize for 'Wavelet Theory'

A French mathematician known for his pioneering work on a theory used for applications ranging from image compression to the detection of gravitational waves from the merging of black holes has earned one of the world's top prizes in mathematics.

Yves Meyer, a professor emeritus in mathematics at the École normale supérieure Paris-Saclay in France, will receive the Abel Prize, the Norwegian Academy of Sciences and Letters (which awards the prize) announced today (March 21) in Oslo. The prize, which comes with a cash award of 6 million Norwegian krone ($710,000), will be bestowed by King Harald V of Norway on May 23.

Meyer was honored largely "for his pivotal role in the development of the mathematical theory of wavelets," the academy said. His work on wavelets began in the mid-1980s.

Two-hundred-terabyte maths proof is largest ever

A computer cracks the Boolean Pythagorean triples problem — but is it really maths?

Three computer scientists have announced the largest-ever mathematics proof: a file that comes in at a whopping 200 terabytes, roughly equivalent to all the digitized text held by the US Library of Congress. The researchers have created a 68-gigabyte compressed version of their solution — which would allow anyone with about 30,000 hours of spare processor time to download, reconstruct and verify it — but a human could never hope to read through it.

Fermat's Last Theorem Prize Approved

It was a problem that had baffled mathematicians for centuries -- until British professor Andrew Wiles set his mind to it.

"There are no whole number solutions to the equation xn + yn = zn when n is greater than 2."

Otherwise known as "Fermat's Last Theorem," this equation was first posed by French mathematician Pierre de Fermat in 1637, and had stumped the world's brightest minds for more than 300 years.

In the 1990s, Oxford professor Andrew Wiles finally solved the problem, and this week was awarded the hugely prestigious 2016 Abel Prize -- including a $700,000 windfall.
