Look up at the stars and not down at your feet. Try to make sense of what you see, and wonder about what makes the universe exist. Be curious.

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.

Hypatia of Alexandria (c. 370–415 AD) was a pioneering female mathematician, astronomer, and philosopher, renowned for her work on conic sections & role as a prominent educator. Tragically, many of her contributions were lost when she was murdered by a mob in 415 AD

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.

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.
