In the same way that DNA has
one strand that cause many
different cells, particles have
many different shapes. Light has
a certain state (remember thatís
the word we use to refer to the
size and shape and even the
speed of a particle), so does
sound and electricity. The
geometry makes all the
difference! If a particle is
shaped in a certain way and
travels at a certain speed, then
it behaves in a certain way.
