"String theory envisions a universe in which there are more dimensions than the four we observe."

"Physics is really nothing more than a search for ultimate simplicity, but so far all we've found is ultimate complexity."

"The universe doesn't owe us comprehensibility."

"Imagination is more powerful than knowledge."

"The world is full of wonders if you know where to look."

"You have the imagination of a child, Lucy"

"The world is full of mysteries waiting to be solved."
