Weak.

That’s how you might describe our ability to observe physics at its limits. Brace yourself for some serious physics calculations set out to determine a proton’s weak charge in a set of mathematical circumstances not easily (or cheaply) manufactured in the real world. The good news? The weak force held strong, not only lending even more support to the current standard model post-Higgs boson but importantly opening the door to whole new worlds of physics enlightenment born solely of pen and paper (and a whole lotta math). | Androić, Nature 2018
