I’ve noticed this too. I think it started around the time of the first round of big tech layoffs in the US, and when the US ratcheted up the price for H1B(?) visas.
Seems like economic uncertainty or fear of it breeds xenophobia. Who knew
There absolutely are direct neutron experiments, but they are much lower energy and have a different focus, partly because neutrons being neutral means they’re very hard to accelerate.
There’s an ultra cold neutron source at Paul Scherrer that is used to measure if the neutron has an electric dipole moment. This is complementary to high energy experiments.
I get what you’re saying, but the measurements are real. In some sense they are the truth.
In the article this refers to the finding that the quark is more complex than three valence quarks.
The measurements indicating that the three-quark-model is incomplete are overwhelmingly conclusive, so some degree of certainty in the language is warranted in my view.
