I lived next door to a rocket scientist for over a year. I dont know what he did at work, but I had to help him out with basic household mechanical type things all the time.

Not impressed.

There is a lot of theory in rocket science. Not everything is materials and technology. You can build a great engine but the rocket will flip in the air and fall on the ground if the theory is just a bit wrong. Theorists are not good at practical things. But they know what a tensor is.
