What are the lessons to be learned from this journey of the mind through the universe? That humans are emotionally fragile, perennially gullible, hopelessly ignorant masters of an insignificantly small speck in the cosmos. Have a nice day.

It would be amazing if something completely spiritual sounding happened. Oh, my gosh! We'd be all over it. Because it's something new about the physical universe.

The problem, often not discovered until late in life, is that when you look for things like love, meaning, motivation, it implies they are sitting behind a tree or under a rock. The most successful people recognize, that in life they create their own love, they manufacture their own meaning, they generate their own motivation. For me, I am driven by two main philosophies, know more today about the world than I knew yesterday. And along the way, lessen the suffering of others. You'd be surprised how far that gets you.

If you look at Einstein's equations and put in low speeds and low gravity, they become Newton's equations.

When we see animals doing remarkable things, how do we know if we're simply seeing tricks or signs of real intelligence? Are talented animals just obeying commands, or do they have some kind of deeper understanding? One of the biggest challenges for animal researchers is to come up with tests that can distinguish between the two.

My goal is not to shove information into your head. It's to find ways to reignite the curiosity that we all had as children for the natural world. You don't have to tell a child to explore the backyard.

Kids are never the problem. They are born scientists. The problem is always the adults. They beat the curiosity out of kids. They outnumber kids. They vote. They wield resources. That's why my public focus is primarily adults.
