Quote by John Wheeler

"Quantum mechanics makes absolutely no sense."

"It is often stated that of all the theories proposed in this century, the silliest is quantum theory. In fact, some say that quantum theory is so counter-intuitive that if you haven't been profoundly shocked by it, you haven't understood it."

"Time is what prevents everything from happening at once."

"The universe is a self-synthesizing machine."

"Perseverance is the key to success."

"Don't give up on what you believe in."

"I've been through worse."

"You learn to live with the pain."
