It reminds me of a question (can be stupid but good ...) that nobody has ever been able to answer precisely ... go I start (but we should create a new topic ...):
Pkoi from 2 very precise frequencies (visible light) EM waves have corpuscular and undulatory behavior ... whereas they only have wave behavior otherwise ...
And as by chance these 2 limits correspond to the precise spectrum of the human eye ...
It is this kind of observation that makes me ... believe that we are not "for nothing" in the Universe ...
that's a good answer?
