It may help (or not) to think of these objects and methods like static 
web pages, being the same for everyone.
Which is why you can't use $this, because it is not particular to an 
instance of the object, but to the whole class of objects.
Likewise, static methods do not operate on an instance


Object->method();

but as shown in the previous post above, and often taking some action 
on a parameter fed to the method like this worthless example


class MyMathClass {
      public static function squareroot($num) {
         return sqrt($num);
      }
  }

MyMathClass::squareroot(4);
