Wine and -1/12

Lately I've been reading about parallel universes and watching Numberphile and Veritassium. I knew my buddy A is deep into physics and math so we've gotten together twice now to discuss over wine.

Tonight this is what we ended up with.

We both work in architecture so some door schedule ranting, and "plan view" of the black hole were included in our scribbles.

Do you know that 1+2+3+4+... to infinity = -1/12? Mind blown? Yeah me too.

It's true and has been proven and works in certain experiments. This was a good way to kick off our wine/physics discussion tonight.
