Carl Sagan
Image
We've arranged a civilization in which most crucial elements profoundly depend on science and technology.
Carl Sagan
Image
There are as many atoms in one molecule of DNA as there are stars in a typical galaxy.

Any civilization that doesn't develop space travel dies.
Carl Sagan

We are at a crossroads in human history. Never before has there been a moment so simultaneously perilous and promising. We are the first species to have taken evolution into our own hands.
Carl Sagan

Recent research shows that many children without enough to eat wind up with diminished capacity to understand and learn (“cognitive impairment” ). Children don't have to be starving for this to happen. Even mild undernourishment — the kind most common among poor people in America — can do it.

In our time, we have sifted the sands of Mars, we have established a presence there, we have fulfilled a century of dreams!
