Today I had to cheer up y daughter who was quite desperate about thermodynamics… so I recalled this
“Ludwig Boltzmann, who spent much of his life studying statistical mechanics, died in 1906, by his own hand. Paul Ehrenfest, carrying on the work, died similarly in 1933. Now it is our turn to study statistical mechanics.”
D.L. Goodstein. “States of Matter” – 1985
And another from a professor of Politecnico di Milano
Nobody truly understand what entropy really is!
