Made of almost nothing I am, If you think of me, you realise you never touch something in your live From the beggining I was here The image you have of me is not very accurate Limitless my number can be Some of me can creat energy In physic you study me (not sport) With your class you had to remember me Around you I am everywhere and nowhere at the same time A, B, or C, an equation have to be solved... Who am I ?
