You could do math early, but there are no brilliant 16-year-old novelists. They don't know the human condition yet.

There's an old saying in the space community: 'If God wanted us to be a spacefaring species, he would have given us a moon'.

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

The greatest teachers are the ones that turn a B student into an A student, or a failing student into a B student.

All the traditional STEM fields, the science, technology, engineering, and math fields, are stoked when you dream big in an agency such as NASA.
