M(77232917) is officially the 50th Mersenne Prime.

M(77232917) was discovered seven and half years ago. Now, thanks to the diligent efforts of many GIMPS volunteers, every smaller Mersenne number has been successfully double-checked. Thus, M(77232917) officially becomes the 50th Mersenne prime.

This is a significant milestone for the GIMPS project. The next Mersenne milestone is not far away, please consider joining this important double-checking effort.

And I'm in it !!

Don't let that put you off ... the rest of it is pretty good.

First time I've seen it in the wild! The Mathematicians' Library on sale at a stand run by Kenilworth Books at #TMiP25

I was so surprised I accidentally signed them all!

When designing games, the basic maths of probability systems can be useful, but also lead to a bit of head-scratching, especially for those of us for whom high school maths lessons have receded somewhat into the fog of ages past. Our archive article for this week, Axes and Arithmetic part one, gives some basic things you might need to know:

We all know, how crappy the common #Mercator projection for world #maps represents areas, inflating them with distance from the equator.

What many people don't know, is why this projection is still so popular:

The shortest path between two points on the globe, is a straight line on the map.

I reckon, this is useful.

In all other projections, the shortest paths are curves.

In #Maths, we say, the Mercator projection preserves angles, not areas.
