"One should always believe in one's own work"

"It is the tension between competing ideas that drives progress"

"The requirement of independence of the results in the two wings"

"Physics may be difficult, but it's not impossible"

"If you cannot explain it simply, you probably don't understand it"

"The laws of physics must not imply a predetermined outcome"

"I became convinced that the experiment could not be done"

"The measurement of incompatible observables cannot both have predetermined results"

"Happiness is found in the pursuit of understanding"

"It is only the impossible that is truly interesting"

"The mind of a physicist is a terrible thing to waste on politics"

"Do not despair when faced with the unknown"

"The universe does not care what you think of it"

"Theories come and go but nature is eternal"

"One must never lose the sense of wonder"

"Simple ideas are often the deepest"

"The question of what is real is a question for philosophers as much as physicists"

"To understand nature, one must listen to what it tells us"

"Faith in reason is the beginning of science"

"The greatest discoveries come from asking simple questions"

"Nature abhors simplicity"

"Each experiment teaches us something, even when it fails"

"The beauty of physics lies in its simplicity"

"One cannot force understanding; it must be earned through hard work"

"The universe is stranger than we imagine"

"It is not the answer that matters, but the quality of the question"

"Science without philosophy is empty; philosophy without science is blind"

"Never accept conventional wisdom without examination"

"The pursuit of truth demands intellectual honesty"

"Hope is the oxygen of the scientist"
