Here are some answers I’ve written on
Why are muons considered to be elementary particles in the Standard Model?
Was X17 predicted before it was observed?
Why is matter-antimatter asymmetry surprising, if asymmetry can be generated by a random walk in which particles go into black holes?
Is naturalness meaningful for non-fundamental theories?
Is there any evidence that dark matter interacts with ordinary matter non-gravitationally?
Does the new finding on “reversing a quantum jump mid-flight” rule out any interpretations of QM?
Why does nature favour the Laplacian?
Why isn’t an infinite, flat, nonexpanding universe filled with a uniform matter distribution a solution to Einstein’s equation?
Why not use this experiment to test gravity’s quantum properties?
Does Feynman’s derivation of Maxwell’s equations have a physical interpretation?
Why are the harmonics of a piano tone not multiples of the base frequency?
Quantum made easy: so what is quantum mechanics all about?
Why do we need complex representations in Grand Unified Theories?
If turning a perfectly monochromatic laser on for a finite time gives a frequency spread, where did the other frequency photons come from?
What are the assumptions that C, P, and T must satisfy?
What is the analog of the Aharonov-Bohm effect for general gauge fields and for gravity?
Is the effective Lagrangian the bare Lagrangian?
Why does having a representation of the Poincaré algebra imply conservation of energy, momentum and angular momentum?
Why is the smallness of Higgs mass not technically natural?
What’s an efficient way to learn simple formulas by heart without understanding?
Do you keep your study notes publicly available?
Is Academia a dying field?
