Trek quote

"Learn why things work on a starship" - Kirk
"Each ship has it's own combination code to prevent an enemy from doing what we're attempting" - Spock
"Using our console to order Reliant to lower her shields" - Kirk

I've always loved this segment from Star Trek: TWOK. To me, it serves as an example that understanding how and why something works the way it does is always better than just knowing how to use it.
