I don't know if reddit or other platforms were like this, but I'm enjoying memes evolving from previous posts from here.

They were! This trend kind of died out because of growth and enshitiffication, and I’m very glad to see it coming back here :)

Various notations appear in older sources were used, such as Ne(22) in 1934,[1]: 226 Ne22 for neon-22 (1935)[2] or Pb210 for lead-210 (1933)[3]: 7
You kids and your newfangled notations *shakes fist at heaven*
I had some really old physics books when I went to school … and that has been a while.

They have been summoned. Soon they will arrive, and they will show no mercy.

I see ^235\ U and I relate an obscure fun fact: separating the isotopes of Uranium is an extremely difficult task because they behave identically in the chemical sense. One of the techniques developed by the Manhattan Project during WWII was electromagnetic separation. When a charged particle (or ion) moves through a magnetic field, it experiences a displacing force that is perpendicular to the direction of motion (which is pretty fucking strange in and of itself - imagine pushing an object on the floor and having the force of friction move it sideways instead of resisting your push).
This force perpendicular to the direction of motion causes the ion to travel a slightly curved path. The electromagnet separation technique involves creating a stream of ionized atoms of unrefined Uranium and firing it through a strong electromagnetic field; because the particles of U^238 and U^235 experience the same force during this, the U^235 ions, being slightly less massive, are displaced a bit more and so follow a slightly more curved path. By placing collectors at different positions, you end up with a small amount of U^235 and a large amount of U^238.
These giant electromagnets would normally have used copper wire for their windings, but copper was a strategically critical material for the war effort and was in very short supply. So the Manhattan Project basically checked out the United States’ silver reserves and used that for the windings instead (silver is not quite as good as copper for this purpose but is obviously better than nothing).
The electromagnets also used a lot of electricity, and this is why the Uranium-refining facilities were located in Oak Ridge, Tennessee. FDR’s WPA had built multiple dams around there during the 1930s, and their turbines were put to work generating electricity for the magnets (it was also used for the thermal and gaseous diffusion processes).
