That does sound nice. I think the author would say that if it's part of your annual performance review, then you are being paid to do it. That's the real test, not the job descript…

You don't ever create plasma via fusion, fusion occurs in plasma that has reached a certain temperature and density threshold.

I think the burden of explanation is on the great great grandparent post which proposed an accelerometer "entirely made out of the same magnetic field" which would let it satisfy a…
