Yes, Quantum Field Theory can be explained through Lie groups. SU(2) is isomorphic to the quaternions of norm 1, and SU(2) is important if you want to understand the Lorentz group and Poincare group, which represent the…
>> ArXiv pre-prints are pretty normal in physics and math. Correct, and they are usually followed up by a published, peer-reviewed paper as well. I look forward to the day this one also gets reviewed and published.…
This result isn't even peer-reviewed yet. All of this hype about the X17 particle is coming from a pre-print on the arXiv. https://arxiv.org/abs/1910.10459 They claim a 7.2 sigma result, but the distribution of the…
Her post linked to in the original blog post makes a good point too: Even if your theory is consistent, it is only as valid as the assumed axioms. Consistency, of course, is necessary in any correct theory of physics,…
I like Physics from Symmetry by Jakob Schwichtenberg as an explanation of how spin arises from a modern understanding of physics. The book was written while the author was a Masters student, and so it is much closer to…
A small correction- it’s not the small mass of the neutrino that allows it to escape quickly, but the fact that they are electrically neutral, and also do not interact with the strong force and do not get caught by the…
