2022-04-27: How the Higgs Mechanism Give Things Mass

  • 04:37: ... Its bosons do have properties  that look like weak isospin and weak hypercharge,   but no electric charge. In our universe  these three quantities are ...

2022-03-16: What If Charge is NOT Fundamental?

  • 10:58: It acts more like electric charge, so we'll be imaginative and call it weak hypercharge.
  • 11:05: And here's the weird thing: weak isospin and weak hypercharge are mixed in exactly the same way as Gell-Mann’s versions of these quantities.
  • 11:14: Which is to say, electric charge equals weak isospin plus half weak hypercharge.

2019-01-16: Our Antimatter, Mirrored, Time-Reversed Universe

  • 03:02: ... all charges switch side electric charge but also quark color charge weak hypercharge etc that's what a switch to antimatter means how does this work in our ...

2017-07-19: The Real Star Wars

  • 15:36: ... interaction, but it's analogous in some ways the Higgs field exchange is weak hypercharged with the electron via W bosons, causing its [INAUDIBLE] to ...

2016-01-06: The True Nature of Matter and Mass

  • 09:06: Felix Feist points out that given that the right-handed electron doesn't have weak hypercharge, shouldn't it be massless?
  • 09:14: The right-hand electron can interact with the Higgs field by picking up some weak hypercharge.
  • 10:06: Then, without an infinite source and sink of weak hypercharge, the weak nuclear force and the electromagnetic force were all the same force.

2015-12-16: The Higgs Mechanism Explained

  • 04:20: It's called weak hyper-charge, which by the way was the name of my high school garage band.
  • 04:48: ... it won't let an electron flip from left to right unless it can ditch its weak hyper-charge or flip back again unless it can pick some ...
  • 05:17: ... weirdness, this complex, multi-component field not only carries the weak hyper-charge, but manages to take on all possible values of this charge ...
  • 05:29: This makes the Higgs field an infinite source and sink of weak hyper-charge.
  • 05:34: ... out of the Higgs field from all directions, giving and taking away the weak hyper-charge on infinitesimally short time ...
