> Marriage, however, proved to be a towering practical problem — Princeton, where Feynman was now pursuing a Ph.D., threatened to withdraw the fellowships funding his graduate studies if he were to wed, for the university considered the emotional and pragmatic responsibilities of marriage a grave threat to academic discipline.

You have got to be kidding me. And I thought academia was bad in the 21st century.

Erwin Schroedinger explained this in 1944 with a quantity called “negative entropy” instead of “assembly”.

You can move the cursor up maybe 10 lines from where you start before going off the edge of the keyboard.

Now try moving down 10 lines from where you start. Hopefully you will see the issue with starting from the spacebar at the bottom edge of the screen.

Maybe we need something like the old thinkpad nub on touchscreen keyboards.

Probably helps that he’s got the regional Orthodox Church in his pocket to reassure him.

Is this named for the science-fiction author Greg Egan, or the TeX.SE guru egreg?

Most of this can be understood with two observations: negative mass has negative kinetic energy and its momentum points opposite the direction of velocity. So if a system composed of negative mass ‘loses’ energy or momentum to the environment it actually gains (negative or absolute) momentum. It’s all very unintuitive of course because it is technically nonsense.
