"We do not believe any group of men adequate enough or wise enough to operate without scrutiny or without criticism. We know that the only way to avoid error is to detect it, that the only way to detect it is to be free to enquire. We know that the wages of secrecy are corruption."
J. R. Oppenheimer

Theoretical physicists live in a classical world, looking out into a quantum-mechanical world. The latter we describe only subjectively, in terms of procedures and results in our classical domain.

The fundamental laws necessary for the mathematical treatment of a large part of physics and the whole of chemistry are thus completely known, and the difficulty lies only in the fact that application of these laws leads to equations that are too complex to be solved.

Physics is like sex: sure, it may give some practical results, but that's not why we do it.

The public has a distorted view of science, because children are taught in school that science is a collection of firmly established truths. In fact, science is not a collection of truths. It is a continuing exploration of mysteries.

Hulk smashing Gammasphere.
Gammasphere was an array of 110 detectors used for many discoveries in nuclear physics in the early 2000s.
It is featured in movie The Hulk (2003) by Ang Lee, where it shoots gamma rays generating the titular green monster, that proceeds to smash the ball.
The array costed 20M$, the Movie 137M$.
Operation Paperclip was a secret United States intelligence program in which more than 1,600 German scientists, engineers, and technicians were taken from former Nazi Germany to the US for government employment after the end of World War II in Europe, between 1945 and 1959.
