Donna Grant

"Since every piece of matter in the Universe is in some way affected by every other piece of matter in the Universe, it is in theory possible to extrapolate the whole of creation - every sun, every planet, their orbits, their composition and their economic and social history from, say, one small piece of fairy cake."

"We are all flawed and creatures of our times. Is it fair to judge us by the unknown standards of the future?"
Quote_1.png
Carl Sagan

Quote_1.png
Carl Sagan

Quote_1.png
Carl Sagan
"There are no forbidden questions in science, no matters to sensitive or delicate to be probed, no sacred truths. That openness to new ideas, combined with the most rigorous, skeptical scrutiny of all ideas, sifts the wheat from the chaff. It makes no difference how smart, august, or beloved you are. You must prove your case in the face of determined, expert criticism. Diversity and debate are valued. Opinions are encouraged to contend"substantively and in depth."

"We are all star stuff."
