comment If there were fundamental forces weaker than gravity, would we know about it?
I like Slovakia! And the idea that Czechia is on par with a "superior landscape" inside a swampland is surely a bit exaggerated. Yes, I think it's a test but there are subtleties that prevented us from formulating and/or proving a truly general version of the inequality, so there may still be loopholes. But I think that it's important to look at both types of evidence in science - not only that "something is possible and goes" but also on general enough principles that resemble "no-go theorems". It's really the latter principles, "something isn't possible", that mostly underlie modern physics.

comment Eigenstates of an observable
Every eigenstate is only orthogonal to another eigenstate if the eigenvalues of the two differ - which isn't guaranteed exactly because one operator isn't (usually) the complete set of commuting observables.

comment Is a “shift in the meaning” of Accuracy and Precision occurring?
No, Brandon, you're wrong. The "shift in the meaning" isn't a claim about linguistics data - usage of language by the physicists or other parts of the public - but a statement about a particular document, ISO 5725, which decided to interpret the terms a bit differently.

comment Electroweak interaction: From $W^{1}_{\mu},W^{2}_{\mu},W^{3}_{\mu},B_{\mu}$ to $W^{\pm},Z_{\mu},A_{\mu}$
In the last two formulae, you meant the squared couplings under the square roots and not the couplings themselves, didn't you? When you make this fix, the eigenstate combinations clearly work out.
