"I have learned that courage is not the absence of fear, but the triumph over it."

"The greatest glory in living lies not in never falling, but in rising every time we fall."

"Education is the most powerful weapon which you can use to change the world."

"Do not judge me by my successes, judge me by how many times I fell down and got back up again."

"Science helps us understand the world."

"I've witnessed the birth of science, and it continues to amaze me."

"I'm something of a scientist myself."

"The fusion process is self-sustaining now!"
