I came here when I stumbled on the Ramanujan sum. It's very weird and it made me think. I came up with some weird questions like "Is there a twilight zone between truth and paradox". I suppose it's a weird question but I would like to know what other people think. It made more sense to be a member of this forum rather than some mathematical one where I fear I would be ridiculed. Have a look at the Riemann Zeta function someone would say I think. Anyway, there are interesting topics and I have given some my five cents of worth in hope that my thoughts won't be found wanting. I live in downtown Stockholm, the capital city of Sweden.
