If you're an adult and you choose not to believe in science, fine, but please don't prevent your children from learning about it and letting them draw their own conclusions.

I like to regard myself as someone who's capable of critical thought, that is to say, who can evaluate claims.

NASA is an engine of innovation and inspiration as well as the world's premier space exploration agency, and we are well served by politicians working to keep it that way, instead of turning it into a mere jobs program, or worse, cutting its budget.

Everyone, red state, blue state, everyone supports space exploration.

I like to keep certain stuff to myself just because I feel like technology is taking over people's lives.

Really think about the way you interact with people, whether it's in person or on the Internet. You have to be very mindful.

As a child, I did what any normal kid who grew up without any electricity would do - I spent countless hours working on a computer wired to my parents' car battery... and learned how to code. This natural passion for computers lead me into the Internet market during the late 1990s and early 2000s.

About half my work in education is U.S. political reform around school districts and charter schools, and creating more room for entrepreneurial organizations to develop. And about half on technology, which I look at as a global platform.
