"I've gradually come to doubt the existence of God more and more as I've gotten older."

"The progress of science is not just a series of discoveries, it's a change in how we think about nature."

"Particle physics is just a way of organizing our ignorance."

"We are at a wonderful moment in human history where we are beginning to understand the fundamental laws of nature."

"The universe is governed by simple and elegant principles, even though it appears infinitely complex."

"I think one of the big problems in physics right now is that we don't have a good understanding of what space and time really are."

"Even the smallest things can reveal the deepest truths about the universe."

"Technology and science are powerful tools, but they're not magic wands that can solve all our problems."

"The way to scientific truth is through systematic doubt and careful observation."

"Supernaturalism has always been a refuge for ignorance and a barrier to scientific progress."

"I think that the idea of personal immortality is not a very attractive idea anyway. It seems to me that it would be a terrible bore."

"The first principle is that you must not fool yourself, and you are the easiest person to fool."

"Science is nothing more than an organized way of asking and answering questions about nature."

"The laws of physics are written in the language of mathematics, which is perhaps the only universal language."

"We now know that all matter and energy in the universe can be understood through a few simple principles."

"The beauty of mathematics is that it reveals the hidden order in nature."

"Physics is just the systematic study of what we can learn about the universe by careful observation and reasoning."

"I think that in the end, science will triumph not because it answers all questions, but because it's the best way we have of asking them."

"The universe is not cruel, it is simply indifferent, which is almost worse."

"There's an aesthetic to physics that you either feel or you don't."

"The progress of science depends on the willingness to question everything."

"If we ever truly understand the universe, we will have understood ourselves."

"The grand challenge of physics is to understand not just what happens, but why it happens."

"Mathematics is the language in which God wrote the universe, assuming God exists."

"Every great physicist has had to struggle against the prevailing prejudices of his time."

"The universe is governed by laws, but those laws allow for a remarkable degree of complexity and creativity."

"I think the most important thing in science is not the discoveries themselves, but the process of discovery."

"We live in a universe that is governed by simple principles, which is itself a profound mystery."

"Science progresses not by accumulating facts, but by developing better and better theories."

"The physicist's job is not to explain reality, but to describe it as accurately as possible."
