Newcastle MathsJam April 2012 Recap

By . Posted

April’s MathsJam was very enjoyable. We did a bit of arts and crafts, a bit of playing games, and if it had been NBA Jam instead of Maths Jam I would have been entirely on fire because I used up all my IQ points solving some very fun puzzles. Durham were still on their Easter holidays so the attendance was a modest six people. That was just enough for everyone to be doing the same thing at the same time, so we had a good time.

HyperRogue II – a roguelike on the hyperbolic plane

By . Posted

I was directed to this game by a retweet by @haggismaths. It’s a roguelike (text-based explorey role-playing adventure game) which takes place on the hyperbolic plane. It’s a lot of fun. It’s hard to get your head round the fact that there’s a lot more stuff in between two lines in hyperbolic space than in Euclidean space, so it’s very hard to find your way back somewhere after it disappears over the horizon.

Conformal Models of Hyperbolic Geometry by Vladimir Bulatov

By . Posted

Vladimir Bulatov makes art, including metal sculptures and jewellery, based on tilings of non-Euclidean spaces.

 

He has posted online some slides he made to go with a talk he gave at the JMM in 2010, about the many ways conformal mappings of the hyperbolic plane can produce interesting images. Quite a few of the diagrams are animated if you click on them, which I missed first time round.

There are a few other slideshows on similar topics on his site.

In addition to all that, Vladimir shares some very cool things on Google+.
