What I got minutes after the science movie

I kind of know that quantum mechanics is talking about that everything is possible, it's just that the chance is large or small. I don't really get what string theory is, and I don't understand what relativity is either. I feel pretty amazed that people can even think of things like this, but I feel pretty dumb not to be able to understand it.

It was organized pretty good, it started from the basic and to the difficult ones. What I didn't like about it was because we forgot to look at the rubric when we were practicing our presentation. I still like it when the teacher teaches, because, then individually, we can spend time on the part we think is most difficult, but if we are learning this way, even if we know our topic clearly, but then I don't know the stuff other people were presenting. Presentation is good, but I think everyone should learn everything.
