A new prime has been found (2018)

The GIMPS project has discovered the largest prime to date... it's a Mersenne prime, which means it is of the form 2^n − 1 for some whole number n. ☺

In this case, it is 2^77,232,917 − 1. This number has 23,249,425 digits, and it's nearly one million digits longer than the previous Mersenne prime found.

Read about the discovery here.

The work to find these really large primes is done by running specialized software on many regular computers -- in fact, anyone with a modern computer can help in this project!

Tiling with pentagons - math news

Here's a well-written article (and easy to read even for laypeople) about a century-old math problem that has finally been solved. It has to do with tiling the plane with PENTAGONS.

In a nutshell, there are ONLY 5 families of convex pentagons that tile the plane. The situation is altogether different, and much easier, for rectangles, triangles, and quadrilaterals.

The article explores and explains these concepts in an easy-to-follow manner and with wonderful graphics. Tilings are something easy to understand, yet when it came to pentagons, the situation turned to be very complex.

This second link shows an image of the 15 families of pentagons that tile the plane.
