This German retiree solved one of world's most complex maths problems - and no one noticed

It's a problem that the world's most experienced mathematicians have spent decades trying to solve, and the solution had eluded them at every turn - the infamous Gaussian correlation inequality (GCI).



Then, out of nowhere, a retired German statistician figured out the proof while hunched over the sink, cleaning his teeth. But rather than being celebrated by the wider mathematical community, the proof went largely ignored. Because how could such an unlikely figure have outsmarted them all?


This paper could be the key to solving a 160-year-old, million-dollar maths problem

When it comes to the fabled Riemann zeta function, the world's best mathematicians have suffered 160 years of dead-end after dead-end. 



But now a trio of mathematicians have discovered a new approach to solving what's been called "the greatest unsolved problem in mathematics", and it just got someone closer to a US$1 million cash prize.


Largest known prime number discovered

A computer in Missouri has discovered the largest known prime number, 2^74,207,281– 1. It is about 22 million digits long, 5 million digits longer than the previous largest known prime, which was discovered in January 2013.

Primes that can be written as one less than a power of two, i.e 2^n – 1 for some n, are known as Mersenne primes after the French monk Marin Mersenne who...

Artificial Intelligence breakthrough as intuition algorithm beats humans in data test

Big-data analysis consists of searching for buried patterns that have some kind of predictive power. But choosing which "features" of the data to analysis usually requires some human intuition. In this case, though, the researchers tested their first prototype system that analysis big-data against human teams in three data science competitions. The machine managed to finish ahead of a total of 615 human teams.
