"You can't stop progress. What you can do is try to guide it."

"The pursuit of knowledge for its own sake is not a waste of time."

"Nature is not democratic; it follows mathematical laws that don't care about our feelings."

"I've always believed that the best way to understand something is to try to explain it to someone else."

"The universe is ruled by chance and necessity, not by intention."

"Scientific progress is made by those who are willing to question everything."

"We are all made of star stuff. The atoms in our bodies were forged in the cores of distant stars."

"The beauty of science is that it allows us to understand the world without appealing to magic or miracles."

"I think the greatest gift we can give our children is curiosity about the world."

"The laws of physics are not negotiable. They are what they are."

"We must learn to live with uncertainty. The world is far more complex than any theory can capture."

"The most important thing in science is to be honest about what you know and what you don't know."

"There's no point in being precise about something if you don't even know what you're talking about."

"Science is a way of learning about nature through observation and experimentation."

"The universe doesn't have to make sense to us. We're just trying to figure out what it is."

"Every person has within them the capacity to understand the fundamental laws of the universe."

"I believe that science and reason are humanity's best tools for understanding reality."

"The more you learn, the more you realize how much you don't know."

"Life is too short to spend it on things that don't matter."

"The fundamental forces of nature are remarkably simple. The universe is built on elegant principles."

"What we need is not more science, but more wisdom about how to use science."

"The purpose of science is to improve human life, not to satisfy idle curiosity."

"There are no shortcuts to understanding the universe. You have to do the work."

"I've spent my life trying to understand the fundamental structure of reality."

"The greatest moments in science come when you suddenly see a pattern you never noticed before."

"Nature is far stranger than any fiction we could imagine."

"The universe is governed by laws that are indifferent to human suffering."

"Science teaches us humility. The more we learn, the smaller we become in the cosmos."

"All the weapons of mass destruction are pointed at us. We need to think seriously about that."

"The burden of proof lies on those who claim that something exists, not on those who deny it."
