Popular and recreational mathematics

This page sums up my activities aimed to popularize mathematics, including a number of talks I've given to general audiences (mostly in Hungary and hence in Hungarian). For popular/recreational mathematics created by others, check out my LINKS page.

Popular math talks

TUDOD? rejtvény-játék

TUDOD? is a (Hungarian) website of riddles I created with the help of a few of my collegues at the University of Szeged in 2016. You get one riddle at a time, usually in the form of a picture, to which the answer is either a positive integer or a single lowercase word. All riddles are connected to higher-level mathematics, which you don't need to know for solving them, but you'll be guided to find out more about it once you did. You can also get 3 hints for each riddle if you get stuck, but your first hint is always the title.

The riddles where originally intended for students of University of Szeged, however anyone can go ahead and try them. If you don't speak Hungarian, consider that as an extra challenge :) Google translate or a dictonary will help you out. There are some puzzles where knowing some undergrad mathematics helps.

Other activities

I regularly help organize outdoor math competitions for children ran by the Hungary-based Mathematics Connects Us Association. The mission of the association is to make mathematics fun for the young generation, in which they are incredibly succesful. They run a number of events from challenges to camps and are able to engage about 14000 kids/year.
