“Physicists have come to realize that mathematics, when used with sufficient care, is a proven pathway to truth.”

“But, as Einstein once said, “For we convinced physicists, the distinction between past, present, and future is only an illusion, however persistent.”5”

“A watch worn by a particle of light would not tick at all. Light realizes the dreams of Ponce de Leon and the cosmetics industry: it doesn't age.”

“When kids look up to great scientists the way they do to great musicians and actors, civilization will jump to the next level”

“We all love a good story. We all love a tantalizing mystery. We all love the underdog pressing onward against seemingly insurmountable odds. We all, in one form or another, are trying to make sense of the world around us. And all of these elements lie at the core of modern physics. The story is among the grandest -- the unfolding of the entire universe; the mystery is among the toughest -- finding out how the cosmos came to be; the odds are among the most daunting -- bipeds, newly arrived by cosmic time scales trying to reveal the secrets of the ages; and the quest is among the deepest -- the search for fundamental laws to explain all we see and beyond, from the tiniest particles to the most distant galaxies.”

“...things are the way they are in our universe because if they weren't, we wouldn't be here to notice.”
