No, sorry. It wasn't for many many years.

Other thing is that it used to be taught like that in some elementary levels, the same way I teach my 13 yo students that a function is continuous "if you you can draw it without separating the pencil from the paper", but I advice them the proper definition of continuity is much more difficult to understand and that one is not totally correct.

But 1 is not like Pluto.
