Have fun playing with curvature

Recently Tim Hutton and Adam Goucher have been playing around with hyperbolic tesselations. That has produced a {4,3,5} honeycomb grid for the reaction-diffusion simulator Ready, which Adam talked about on his blog a couple of days ago. Tim has also made a much simpler toy to play with in your browser: a visualisation of mirror tilings (the Wythoff construction) in spaces with different curvatures.

Hyperplay lets you select the kind of regular polygon you want to tile, and then your mouse controls the curvature of the space it sits in. Certain curvatures produce exact tilings of the space – for example, triangles tile a space with zero curvature – and you get projections of polyhedra for certain positive curvatures.

George Green: Nottingham’s Magnificent Mathematician

We don’t regard him as a miller, I’m afraid, we regard him as a very eminent mathematician whose work today is still being used in major industries and concerns.

– George Saunders, descendant of George Green, on being asked a question about bags of flour on the Alan Clifford show on BBC Radio Nottingham of 11th September 2014 (starts approx. 1:16).

The above quote is from a short interview with George Saunders and Kathryn Summerwill on BBC local radio about George Green. Green, of whom you may have heard, was a mill-owner in Nottingham and a genius mathematical physicist. The interview marks the opening of an exhibition, curated by Kathryn, ‘George Green: Nottingham’s Magnificent Mathematician‘ in the Weston Gallery at the Lakeside Arts Centre, University of Nottingham.

Zaha Hadid’s design for the Science Museum’s new maths hall is certainly something

For a while, the Science Museum has been forming groups and making noises and tickling rich people with the aim of working out how they’re going to update their rather neglected maths hall. Yesterday they made an unexpectedly positive announcement: they’ve been given £5 million by rich people David and Claudia Harding, and Dame Zaha Hadid has drawn up a swooshy new design.
