## 16 Mar 2022 [What If Charge is NOT Fundamental?](https://www.youtube.com/watch?v=esayi49OAk4&list=WL&index=1)

- Heisenberg - about neutron-proton - isospin symmetry - 1932

but the difference is a proton CHARGE!?

- Nishijima and Gell-Mann - hypercharge 

**electric charge = isospin + (1/2) hypercharge**

isospin and hypercharge are more fundamental???
Gell-Mann predicted Omega-baryon

- Gell-Mann - quarks of of SU(3)

strong nuclear force - quantum chronodynamics

- the secrets of electric charge hides in WEAK force

chirality
electrino-neutrino - another/weak ISOspin
W-boson
Z-boson

left-handed
**weak isospin is effectively a charge of weak force carried by W-bosons**
second charge - weak hypercharge - electric charge carried by Z-bosons
AGAIN **electric charge = weak-isospin + (1/2) weak-hypercharge**
11:20 min

electrons, neutrinos, quarks - fundamental
electric charge is driven by weak force

- electroweak force were unitied

breaking of electroweak symmetry and **the appearance of Higgs boson!**
is the mass fundamental???
