For years and years this has been my least favorite part of school’s curriculum. Too much messy drawing on the board, too much mathematical formulas, and from student’s point of view this was just empty talk. I naturally tried and tried to explain this to my students as best as I could, but even with experiments, that I could demonstrate during the class, I’ve felt that my students been missing the point. They would just try to memorise whole thing without any critical thinking, and let’s face it, what kind of a teacher would I be to let that happen? Most of my colleagues agreed that this is not an easy part of curriculum which it’s hard to be understood even by older students at faculties, and that it is meant only for top of class.

Now, don’t get me wrong. I am not saying that this was unnecessary part of school’s curriculum. This is fundamental part of physics. This was one of the first mistakes made by Newton. And shockingly this is where quantum mechanics starts (thank you Feynman). So I really needed to help my students learn more about this, but how?
