Quote by Roger Federer

"I appreciate the opportunity to play in front of my home fans"

"Tennis has given me everything"

"The moment of victory is much too brief to live for that and nothing else"

"I still have a few years left, I hope"

"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!"
