Quote by Led Zeppelin

"I've been dazed and confused for so long it's not true"

"The song remains the same"

"Whole lotta love is what I need"

"Black dog on my trail"

"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!"
