Just to give an example of what speeder means by "students here don't know jack shit": Over the years I have told friends and peers that, in a perfect vacuum and without taking into account the curvature of the earth, a bullet fired from a gun that's completely level and another bullet dropped from the same height, at the same time, will hit the ground at the same time. Everyone disagrees, says that of course the bullet from the gun will take much longer to fall etc, etc. Now, this is all people who went to private schools and had three (yes, three) years of physics (because if you go to high school here and your school is not a shitty public one, you will have physics for 3 years. You can't choose). I even argued with a friend of mine who is a geologist and works at Brazil's huge oil company Petrobras. You might say "oh, a couple of people, that's anecdote". Yes, it is, but it is just a couple of people because after the fifth I just said "screw it", no one learns physics here.
