SUPERSOLID, WITH A TWIST
The strange quantum phenomenon known as supersolidity
occurs when atoms flow without friction through a solid block
of helium, possibly along a network of defects extending through
an otherwise perfect crystal. In an upcoming issue of Physical
Review Letters, physicists find such a flow in computer simulations
even when the atoms that make up the defects form a regular
pattern, unlike the disorderly arrangement used in previous
calculations. The results open a new way of understanding this
extraordinary state of matter, which has properties of both solids
and liquids.

When you have a theory that gives strange results,
and you plug it into a computer..................
voila!!....
garbage in- garbage out.

Strange results are at the heart of science John... otherwise it
would be dead!


Neat story Sam.

Good one.
