Review: Pythagoria


Pythagoria is a puzzle game for PCs. It’s the same idea as Naoki Inaba’s Area Maze: you’re shown a geometric construction, not drawn to scale, and you have to work out a missing length or an area.

Each puzzle is constructed so that it can be solved without ever dealing with fractions, though what exactly that means is up for debate. Whatever it means, it keeps you from breaking out pen and paper to solve a problem algebraically, when you know there should be a way of doing it in your head.

Relatively Prime Recap: Season 2, Episode 3: Mathematistan


I have to say, I chuckled: the week Relatively Prime hits ‘noteworthy’ on iTunes is the week Samuel discusses using maths to do well in popularity contests. Coincidence? I think not.

To me, episode 3 of the second series represents something of a return to form for one of the top half-dozen maths podcasts around; whether this is because I’m a fan of political maths or because it’s genuinely really good is a) difficult to tell because I’m biased and b) a false dichotomy.

Relatively Prime: Your Daily Recommended Math

Maths – as teachers are fond of telling anyone who’ll listen – is everywhere.

Relatively Prime Recap: Season 2, Episode 1: The Lexicon


I’ve been waiting for the new season of Relatively Prime for more than three years. I’ve listened to Chinook, the highlight of Season 1, countless times since then. And finally, finally, it’s arrived in my podcast feed.

Woo, and for that matter, hoo!

Mathematical app roundup, October 2015

Maths homescreen

I notice that our post queue is filling up with interesting mathematical apps, so I thought I’d deal with them all in one big roundup post. Read on for a mix of mathematical games, apps to help with calculations, and some frankly awful art.

Review: Unique polyhedral dice from Maths Gear

Our good friends at Maths Gear have sent us a tube of “unique polyhedral dice” to review. The description on says they’re “made from polyhedra you don’t normally see in the dice world”. My first thought was that we should test they’re fair by getting David to throw them a few thousand times but — while David was up for it — I’d have to keep score, which didn’t sound fun.

So instead we thought of some criteria we can judge the dice on, and sat down with a teeny tiny video camera. Here’s our review:
