"I've been chasing the idea of using (abusing?) CSS grid to build a interconnected hexagonal grid, where each hexagon fits together seamlessly. An example of this would be a lot of tabletop war games, some board games (Settlers of Catan, for instance), and some computer games (I used to play The Battle for Wesnoth, it uses a system like this)."

"Mathematics and magic may seem a strange combination, but many of the most powerful magical effects performed today have a mathematical basis. Maths is also the secret behind the technologies we use, the products we buy and the jobs we do. The Manual of Mathematical Magic is packed full of magical miracles to impress and entertain your friends. The secrets behind street magic, close-up and stage tricks are explained clearly with instructions and videos to help you perform them perfectly. Then you can learn about the maths behind the trick and discover how that same mathematics is used to power our modern world and numerous careers."

In recent times, there have been a couple of tremendously popular blog posts explaining JOINs using Venn Diagrams. After all, relational algebra and SQL are set oriented theories and languages, so it only makes sense to illustrate set operations like JOINs using Venn Diagrams. Right? Google seems to say so: Everyone uses Venn Diagrams to…

Pascal’s triangle, which at first may just look like a neatly arranged stack of numbers, is actually a mathematical treasure trove. But what about it has so intrigued mathematicians the world over?

"Ana tackles an interesting problem here: what happens when the stroke of an element grows it such that it appears cut off? Getting it to fit tightly again may seem like an exercise in guessing, checking, and magic numbers. But if you know Ana's work, you'll know she is uniquely qualified to teach us the math behind getting to the correct solution."
