Your math teacher, Darth Vader. (Boy, is he strict!)
The ability to calculate the length of the hypotenuse is insignificant next to the power of the force.
I have to add — I would have noted that Vader’s board skills leave something to be desired, but he might have found my lack of faith to be disturbing.
I always thought it would be fun to teach a physics class in Yoda’s voice. “ma = F, it does!”
