Argonne National Laboratory Updated 2025-07-16
This is where they moved the Chicago Pile-1 after they decided it might be a bad idea to run highly experimental nuclear reactions right in the middle of one of the most populous cities of the United States.
After it was reassembled, the Chicago Pile-1 was renamed as Chicago Pile 2 (CP2).
So more precisely, it is a continuation of the Metallurgical Laboratory.
It's still not that far though, only about 20 kilometers, and today is also a populated area.
Ciro Santilli maintains that they chose the site because the name is so cool. Wikipedia says it is derived from the Forest of Argonne, maybe it even shared etymology with the element argon.

Arkarya Updated 2025-07-16
Name of the clade of archaea plus eukarya proposed at: www.frontiersin.org/articles/10.3389/fmicb.2015.00717/full. Much better term than prokaryote as that is not a clade. Let's hope it catches on!
SARS-CoV-2 accessory protein Updated 2025-07-16
Unlike SARS-CoV-2 non-structural protein, these are not needed for test tube reproduction. They must therefore be for host modulation.

Source. Amazing how they used control signals to hide the information from officials on either side.
Principal quantum number Updated 2025-07-16
Determines energy. This comes out directly from the resolution of the Schrödinger equation solution for the hydrogen atom where we have to set some arbitrary values of energy by separation of variables just like we have to set some arbitrary numbers when solving partial differential equations with the Fourier series. We then just happen to see that only certain integer values are possible to satisfy the equations.
This is a bit "formal hocus pocus first, action later". But withing that category, it is just barely basic enough that 2021 Ciro can understand something.
