“Science is an intellectual journey, and to me, it's not the destination, it's the journeyto get there. It's a way of thinking and it's an intellectual curiosity, a desire to know how the world works, and to know what the fundamental principles of the world are, and to know our place in it. I think once we stop asking questions like "what is the age of the universe," or "how are the instructions of DNA carried out on a microscopic level," once we stop asking questions like that, we're dead.”
