All tweets are tasty. Any tweet anybody writes is tasty. So, I try to have each tweet not simply be informative, but have some outlook, some perspective that you might not otherwise had.

Passion is what gets you through the hardest times that might otherwise make strong men weak, or make you give up.

I always try to get people a different outlook. When you do that, people take ownership of the information. They don't ever have to reference me because, I'd like to believe as an educator, I'm empowering them to have those thoughts themselves.

I try to show the public that chemistry, biology, physics, astrophysics is life. It is not some separate subject that you have to be pulled into a corner to be taught about.

Those who see the cosmic perspective as a depressing outlook, they really need to reassess how they think about the world. Because when I look up in the universe, I know I'm small but I'm also big. I'm big because I'm connected to the universe, and the universe is connected to me.

We live on this speck called Earth - think about what you might do, today or tomorrow - and make the most of it.
