“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.”

“Soon earth will cover us all. Then in time earth, too, will change; later, what issues from this change will itself in turn incessantly change, and so again will all that then takes its place, even unto the world's end. to let the mind dwell on these swiftly rolling billows of change and transformation is to know a contempt for all things mortal.”
― Marcus Aurelius, Meditations
