Speaking of “tedious” I don’t know if I’m the only engineering student who found it droll that in the calculus of the thermodynamics of engines, one literally speaks of T*dS work. (Temperature on absolute scale multiplied by differential increment in entropy.) Did someone come up with S to stand for entropy just to produce that pun???
Sounds like a good explanation instead of just saying they ran out of letters to use as symbols. Just like 'p' for momentum.
I tell people they picked 'p' since it was first used to find the momentum of a stream of urine. Especially useful if you REALLY have to go.
Another geek oddity in physics is that "mass = rho v" but not Mass times Wade does not equal Roe v. Wade.
Oops. Got an extra “not” in there.
