Hi right now I do not have school but I was thinking about what my chemistry teacher said last year. he was telling us about electrons and how they move from negative to positive. he said something along the line of: lets you would put a fork in a wall socket and by chance you first hit the positive side nothing happens and when you hit the negative side the system is closed and still nothing will happen because only now the electrons will start moving in an already completed track. sometimes when I correct one of my science teachers they tell me that they do not always tell the whole story or lie to make it easier for the class to understand the general line. so I was thinking is this a real possibility?
