1+2+3+4+… = -1/12, Ramanujan's Sum 📺
1+2+3+4+... = -1/12 wow. How is it possible?
that's called Ramanujan's sum.
you can learn it from the first 15 min of John Baez's lecture
this is quite amazing, touching on several things. See:
- Ramanujan summation
- 1 + 2 + 3 + 4 + …
on a separate note, the rest of Baez's video is also extremely interesting. It introduces you to concepts of string theory, quantum mechanics, spinor theory. See: John Baez on Octonion 📺
