Teresa, I have trouble visualizing the braille telescope, anyway, so that probably wouldn't have been a good career choice. But physics--it seems like we spend much of our lives trying to NOT prove the rules of physics. Anyone can do that! (i.e., "If I hold this really hot full bowl level I can carry it to the table without the contents gaining energy from my motions and waves forming that will slosh over the side of the bowl, burning my fingers in the heat transfer and causing a damp spot of such viscosity on the floor that I'll slip in it.")
