Dear Olaf
Thank you for constructional criticism of my essay. It benefits rather than complimenting from nonprofessionals.
I will try to answer your questions.
1.My observation 18 deg concerning only pseudoscalar mesons where spin=0 and two charged leptons(mu and tau) where spin=1/2.But 18 deg no so important than symmetry around proton.This is an amazing symmetry was not noticed until now.
2.Puzzle of 137 is more sophisticate than 1836,because contains 3 components (c,e,h) whereas 1836 contains only one(mass) component
Cheers
Yuri
