Find
out the difference between a proton and a positron.
See why antimatter isn't. Discover why you are
made of matter that's as old as the universe.
Scientists at CERN, the European Consortium
for Nuclear Research, use some of the biggest
tools in the world -- accelerators -- to look
at subatomic particles, the tiniest things in
our universe.
A
live video link will take you to locations around
CERN: the Antiproton Decelerator, a particle
detector and CERN's treasury of vintage science
tools, and more. We'll meet with scientists,
machine operators, control-room jockies and
others who make CERN a vibrant exciting location
for doing science. We'll find out if scientists
really think there is a parallel universe, take
a look "under the hood" of their experiments,
and find out what cool tools they use to do
their work.
You'll need
the
Real
Player

11 a.m. PDT (8 p.m. CHT):
The Heart of the Matter: A Look Inside Cern
What is antimatter and why are scientists studying it? How is the world's largest particle accelerator constructed? The Exploratorium's Rob Semper talks about how science is done at CERN.

1 p.m. PDT (10 p.m. CHT):
Exotic Atoms and Antihydrogen:
Three Cool Experiments in the AD, part II
Making antihydrogen is no easy matter. Rearchers at CERN show Melissa Alexander and Tom Humphrey where positrons live and how they keep them as cold as deep space.
