derived smooth manifold
A derived smooth manifold is the generalization of a smooth manifold in derived differential geometry: the derived geometry over the Lawvere theory for smooth algebras ($C^\infty$-rings):
it is a structured (∞,1)-topos whose structure sheaf of functions is a smooth (∞,1)-algebra.

Analyzing car efficiency at different power outputs (accelerations)
Physics dictates that the amount of energy required to accelerate a given mass to a specific velocity is independent of the acceleration. (Final kinetic energy = 1/2mV^2 => how fast you got there
doesn't change the amount of energy required).

Irreversible process
A reversible process does not imply that system entropy is not changing, but univers entropy not increasing. So, the process can proceed in such a way that system entropy does not change and entropy
of the system environment (the univers) will increase. So such a process would be irreversible.
