“What I am going to tell you about is what we teach our physics student...” — Richard P. Feynman Quote

“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.”

“When I was a young man, Dirac was my hero. He made a breakthrough, a new method of doing physics. He had the courage to simply guess at the form of an equation, the equation we now call the Dirac equation, and to try to interpret it afterwards.”

“All the evidence, experimental and even a little theoretical, seems to indicate that it is the energy content which is involved in gravitation, and therefore, since matter and antimatter both represent positive energies, gravitation makes no distinction.”

“I think it's much more interesting to live not knowing than to have answers which might be wrong. I have approximate answers and possible beliefs and different degrees of uncertainty about different things, but I am not absolutely sure of anything and there are many things I don't know anything about, such as whether it means anything to ask why we're here. I don't have to know an answer. I don't feel frightened not knowing things, by being lost in a mysterious universe without any purpose, which is the way it really is as far as I can tell.”

“There is a cult of ignorance in the U.S. The strain of anti-intellectualism has been a constant thread winding its way through our political and cultural life, nutured by the false notion that democracy means that "my ignorance is just as good as your knowledge.”

“I actually wanted to be a doctor. But doing all those horrid rat dissections made me faint. I studied science till the 12th standard and later took up commerce. I was planning to do chartered accountancy, but fate had something else in store for me.”

“Fascinating ... The whole thing [the school dance] seems to work on a similar principle to a supercollider. You know, two streams of opposingly charged particles accelerated till they're just under the speed of light, and then crashed into each other? Only here alcohol, accentuated secondary sexual characteristics and primitive "rock and roll" beats take the place of velocity.”

“When you are loved, you can do anything in creation.”

“Chemistry is not torture but instead the amazing and beautiful science of stuff, and if you give it a chance, it will not only blow your mind but also give you a deeper understanding of your world.”
