Some of our professors give the information so complete that we even don't need to buy textbooks. It is very helpful. I'm ready to write down all lectures just to make my education a little bit chipper. One of the best professors explains everything very good but often forgets to give us the opportunity to write down the information. So after the class you feel that you have complete understanding of the material but later when you need to refresh the information you feel that you need these notes you forget to make. Notes are very helpful.

I think, Math is a language of Physics; and Physics is a description of real fenomena. So how we can unerstand anything using just formulas? Good understanding works in order: i) event (description & picture), ii) physics of event, iii) description in formulas. Not vice versa.

up to me, the graphical representation helps much more than simply explained or expressed in formulas. It is much easier to understand and remember, if the information is supported by pictures. Especially for some complicated topics. Though, for these topics it is not always possible

Do you know why hippopotamus have red eyes? To hide themselves in tomatoes! What? You didn’t see hippopotamus in tomatoes? Well, it means that they hide themselves very well!
