Made by The Wizard, a chemistry student in Germany.

I try to share one science problem per day – mostly chemistry, physics, or math – along with a possible line of thought or solution afterward.

I made this site because I noticed I understand things better when I sit with a problem before being told how to think about it. The places my thinking runs out turn out to be the best starting points for everything that follows. That's the whole idea.

The name points at what I'm after – developing an understanding of ideas simple and deep enough that if something came up, a napkin and a pen would do.
