Science is not a subject you took in school. It's life. We are wrapped by it, in it, with it.

If you're scientifically literate, the world looks very different to you, and that understanding empowers you.

We already know the limits of Einstein's theories. From the centers of black holes at the very beginning of the universe - we call these singularities - Einstein's equations fail. In fact, people have joked that's where God is dividing by zero.

I would request that my body in death be buried not cremated, so that the energy content contained within it gets returned to the earth, so that flora and fauna can dine upon it, just as I have dined upon flora and fauna during my lifetime

I lose sleep at night wondering whether we are intelligent enough to figure out the universe. I don't know.

Recognize that the very molecules that make up your body...are traceable to the crucibles that were once the centers of high mass stars that exploded their chemically rich guts into the galaxy, enriching pristine gas clouds with the chemistry of life. So that we are all connected to each other biologically, to the earth chemically and to the rest of the universe atomically.

Practically every food you buy in a store for consumption by humans is genetically modified food. There are no wild, seedless watermelons. There’s no wild cows.
