“Quantum field theory is the basic tool to understand the physics of the elementary constituents of matter. … It is both a very powerful and a very precise framework: using it we can describe physical processes in a range of energies going from the few millions electrovolts typical of nuclear physics to the thousands of billions of the Large Hadron Collider (LHC). And all this with astonishing precision.”

“In physics, energy has a very precise definition: it is what characterises something changing in the world surrounding us. [...] Counting energy is therefore nothing else than counting how much the world has changed.”

Jean-Marc Jancovici (1962) French engineer and energy climate specialist

“On the side of physics, there were a few key figures in Oxford who realized, in all probability unlike the majority of their colleagues in the physics department, that physics without interpretation is only part of the story, and that theories like quantum mechanics need careful foundational reflection.”

Harvey Brown (philosopher) (1950) Philosopher of physics
