just enough to appreciate it. i didn't have the math skills to be a controls engineer, but i did design electromagnetic devices for a while, and totally envied the controls people who got to tie all the pieces together - electrical, electronic, mechanical, etc. my favorite example is the video of the apollo lunar module making adjustments as it approached the command module.
