The same year (1785) that Sade was in prison writing this book, Charles-Augustin de Coulomb published his paper on the electrostatic force between two charges. This is now known and studied as Coulomb’s Law, in which he even has a constant (a Coulomb) named after him. This paper was monumental and allowed for even more discoveries about electromagnetism (my favorite part of physics) to be made. 

Sade is the origin for the word sadism. 

I will not be rating this book other than to say that it is very clear this is an unfinished piece of writing and interesting to see the political aspects (and how they can relate today).
