Quote by Langston Hughes

"I've known rivers ancient as the world and older than the flow of human blood in human veins."

"Hold fast to dreams, for if dreams die, life is a broken-winged bird that cannot fly."

"Life for me ain't been no crystal stair."

"I am my mother's son. I wear the colors she gave me when I was born."

"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!"
