Quote by Isaac Newton

"If I have seen further, it is by standing on the shoulders of giants."

"The greatest force in the universe is not gravity, but human potential."

"I can calculate the motion of heavenly bodies, but not the madness of people."

"Nature and nature's laws lay hid in night; God said, Let Newton be! and all was light."

"Friendship is built on trust and honesty."

"True friendship is worth more than gold."

"Good friends are like stars, always there even when you can't see them."

"Friendship means sacrifice."
