First of all, thanks.

The only reason we teach classical physics is that it is easier than quantum physics. If everyone could learn quantum physics, there would be no need to teach classical physics anymore.

Really? Isn't classical physics used in some contexts because the difference between the classical model and reality isn't enough to justify extra complications? I'm thinking specifically of engineers.

True. Revised sentence: the only reasons for using classical physics are that it is easier to learn, easier to calculate with and it helps you understand people who know only classical physics.
