- An easy way to construnct "lower than zero"-temratures:
-
- All you need is a magnetic material and a strong magnet.
-
- Then 1) Cool the whole thing and switch an the magnet.
-
- 2) Wait until ALL spins are orientated upwards.
-
- 3) Change the direction of the field.
-
- So the spin are all looking against the lines of the field. The is identified
- with negative absolute tempratures. But this is only a statistical definition.
