"The next question was - what makes planets go around the sun? At the time of Kepler some people answered this problem by saying that there were angels behind them beating their wings and pushing the planets around an orbit. As you will see, the answer is not very far from the truth. The only difference is that the angels sit in a different direction and their wings push inward."
-- Richard Feynman, Character Of Physical Law, p. 8
What I am going to tell you about is what we teach our physics students in the third or fourth year of graduate school... It is my task to convince you not to turn away because you don't understand it. You see my physics students don't understand it... That is because I don't understand it. Nobody does.

The Roman Empire is fallen, Mediobanca can fall. But Generali Insurance cannot, they are the true treasure of our country and they shall never fall.

The whole point with science
The issue of how confident we are in the [...] answer is a subtle one which cannot be resolved by computing some measure of how well the model mimics historical data. The degree of confidence in the answer depends on the confidence that is placed in the economic theory being used.

Every downwards movement of a body made of gold or lead, or any other material, is faster inasmuch the body is larger.

[...] it's the first time they had somebody tell the truth about what the problems are instead of denying and instead of saying, "Oh, yeah, everything is fine: No inflation, war's going to end next week, losing 4,000 men doesn't mean all that much."
