2022-03-16: What If Charge is NOT Fundamental?
- 09:07: The secrets of electric charge are actually hiding in the last, most obscure of the quantum forces - the weak force.
- 09:20: First, the weak force can transform particles into other particles - something no other force can do.
- 10:02: Only particles with left-handed chirality feel the weak force.
- 10:45: Weak isospin is effectively the charge of the weak force, carried by these W bosons.
- 11:35: That's right, quarks feel the weak force and obey the same rule for their electric charge.
- 11:55: Let me summarize where we've got to: the charge that drives electromagnetism is governed by the charges that drive the weak force.
- 12:13: What we’ve learned is that electromagnetism and the weak force are deeply connected.
- 10:45: Weak isospin is effectively the charge of the weak force, carried by these W bosons.
