Pretty fun, being an engineer myself I knew most of them, but still, with the time limit it's difficult to get some of them right :D Would definitely throw in some randomness in there so you don't always get the same questions and also that the given answers are not on the same positions each time.
Also, scoring system should have a bit more range, right now I can see people getting the same score.
But definitely had fun with it and I liked the humor, starting with the name Dr. Scientist, got a chuckle out of me
