As a former physicist it also made me angry that they used geometry, when teaching us about multi-dimensional algebra. Professor would tell us that vectors are orthogonal to each other, but not telling us what it actually means is, that changing one of them doesn't affect other. I mean, yes, in hindsight, this information was there, however, when you are just starting to learn something, you have a problem filtering, what is really important and what not.

And for example, a real revelation with regard to infinity came, when I read (or heard somewhere, it was long time ago) that infinity can sometimes be few millimeters or even micrometers. Up until then I always imagined some really large number, but at that point I realized, you need to put problem before you need to put problem before you into perspective.
