Discovery of the day

Two of the walls of my office are made of metal.

Now I know what I want for my birthday.

Magnets.

Not all metals are magnetic. Aluminum, for instance is not only not magnetic, it's dia-magnetic. It will actually REPEL a magnet if the magnet is moving too fast, because the magnetic flux lines will bend back in such a way that it creates a "virtual" magnetic field that repels the magnet away.

And stuff.

So THERE. :)

Well, true. But I did try a magnet on the wall, and it stuck.
