## Math, Santa, and Venn Diagrams

It’s nearly Christmas, so I’d like to have some rest and avoid serious math posts. To be honest, I’m really thinking about the costume that I’m going to wear tomorrow for our Any Costume Christmas party. I’m thinking about a Dragon Ball Z costume (Vegeta perhaps?). I suppose we have the same height (lol).

Anyway, I found a Venn diagram (see, it’s still related to math), with Santa on the intersection. You would probably agree with me that the one who thought about this is a genius.

By the way, a Venn diagram is a schematic diagram that show logical relations between sets (sorry can’t help it). Venn diagrams are used in elementary set theory especially to represent set relationships in probability, logic, statistics, and computer science.

We had been very serious these past few weeks, so I think we need an ice breaker.  I found this photo at A Geek Story through Great Maths Teaching Ideas and I really like it very much.

Hope you like it too.
