There are as many atoms in each molecule of your DNA as there are stars in the typical galaxy. This is true for dogs, and bears, and every living thing. We are, each of us, a little universe.

There are no wild, seedless watermelons. There's no wild cows... You list all the fruit, and all the vegetables, and ask yourself, is there a wild counterpart to this? If there is, it's not as large, it's not as sweet, it's not as juicy, and it has way more seeds in it. We have systematically genetically modified all the foods, the vegetables and animals that we have eaten ever since we cultivated them. It's called artificial selection.

I've found that no one complains about pop culture being a source of someone lecturing to them. If someone's telling you about Kim Kardashian, you're not going to accuse them of lecturing to you. If I can explore an intersection between pop culture and science literacy, then it generally will not come across as a lecture.

Stars die and reborn […] They get so hot that the nuclei of the atoms fuse together deep within them to make the oxygen we breathe, the carbon in our muscles, the calcium in our bones, the iron in our blood. All was cooked in the fiery hearts of long vanished stars. … The cosmos is also within us. We're made of star stuff. We are a way for the cosmos to know itself.

The day that you stop looking - because you're content God did it - I don't need you in the lab. You're useless on the frontier of understanding the nature of the world.

One of the reasons we're here, that we exist at all, is that Earth, cosmically speaking, is in a relatively peaceful place: orbiting our Sun in a near perfect circle.

As areas of knowledge grow, so too do the perimeters of ignorance.
