कार्लो रोवली काय म्हणतायत पहा .रिचर्ड फाईनमन यांच्या बद्दल: “The greatest physicist of the second half of the twentieth century”
Richard Feynman:
"We absolutely must leave room for doubt or there is no progress and there is no learning. There is no learning without having to pose a question. And a question requires doubt. People search for certainty. But there is no certainty. People are terrified – how can you live and not know? It is not odd at all. You only think you know, as a matter of fact. And most of your actions are based on incomplete knowledge and you really don’t know what it is all about, or what the purpose of the world is, or know a great deal of other things. It is possible to live and not know."

Carlo Rovelli, ‘Reality Is Not What It Seems: The Journey to
Quantum Gravity’, 2014:
“....The greatest physicist of the second half of the twentieth century, Richard Feynman, wrote at the beginning of his wonderful introductory lessons on physics:
If, in some cataclysm, all scientific knowledge were to be destroyed, and only one sentence passed on to the next generation of creatures, what statement would contain the most information in the fewest words? I believe it is the atomic hypothesis, or the atomic fact, or whatever you wish to call it, that all things are made of atoms – little particles that move around in perpetual motion, attracting each other when they are a little distance apart, but repelling upon being squeezed into one another. In that one sentence you will see an enormous amount of information about the world, if just a little imagination and thinking are applied.

Without needing anything from modern physics, Democritus had
already arrived at the idea that everything is made up of indivisible particles.
How did he do it?...”
