Roland Omnès (18 February 1931 – 2 August 2022) was a French physicist and author of several books that aimed to give non-scientists the information required to understand quantum mechanics.
Omnès was Professor Emeritus of Theoretical Physics in the Faculté des Sciences at Orsay, at the Université Paris-Sud XI.
Nevertheless, it is now possible to see that common sense and quantum reality are compatible with each other: we can enter the world at either starting point, and we will find that each leads to the other: experiment leads to theory, and the theory can now recover the common sense framework in which the experiment was conducted (and in which our lives are lived)."
The relationship between the two accounts is as follows: The Copenhagen interpretation of quantum mechanics (argued for most centrally by Niels Bohr) advises that physicists "shut up and calculate".
Omnès claimed that there is a self-consistent framework that enables recovering the principles of classical common sense—and knowing, precisely, their limits—starting from fundamental quantum law.
