This is very impressive!
If you add together all the positive numbers there is, that is the sum of ALL natural numbers from 1 to infinity, you get an astounding result.
You’d think it would be infinity too, but it’s not!
This is, by a wide margin, the most noodle-bending counterintuitive thing I have ever seen. Mathematician Leonard Euler actually proved this result in 1735, but the result was only made rigorous later and now physicists have been seeing this result actually show up in nature. Amazing.
Of course the actual truth seems more complicated, hinging on what “sum” means mathematically, etc.
How do you like them −1/12 apples?
