    WATERLOO, ON, Oct. 31 /CNW/ - International researchers at the Large
Hadron Collider (LHC), in Geneva, Switzerland, will soon embark on one of
science's greatest adventures. With its very high energy, previously seen only
in cosmic rays, the particle collider will probe the inner structure of matter
at distances ten times smaller than any previous experiments. The LHC will
address many of the mysteries surrounding the smallest particles of matter. It
may also pierce secrets that the Universe has hidden since the early stages of
the Big Bang, such as the nature of dark matter and the origin of matter
itself. This will be the largest scientific experiment ever attempted and the
complex international efforts to bring the 27 km-long machine to life,
including Canada's involvement, will also be explained.


    About John Ellis:

    Born in London on July 1st, 1946, Ellis grew up in Otters Bar, a suburb
that some Londoners used to regard as the northern boundary of civilization.
Following a year at the Stanford Linear Accelerator Center and an additional
year at the California Institute of Technology as a research associate, Ellis
joined CERN in 1973 and became leader of the Theory Division for six years.
Currently, he is a senior staff member. Ellis is also an advisor on CERN's
relations with non-Member States.
    Commenting on his efforts, Ellis feels fortunate to work on issues
involving cosmology and particle physics. He says - "Nowadays, I am lucky to
work on both subjects, often in the same research paper, as the two subjects
have really grown together. One of the most exciting aspects of our subject is
how the physics of the very small can be used to describe the Universe on the
largest possible scales."

    About Robert S. Orr:

    Professor Orr was born in Iran, and grew up in Scotland and South Wales.
At present he is a Professor in the Department of Physics at the University of
Toronto. He was NSERC Principal Investigator for ATLAS Canada from 1994 to
2007. ATLAS is a detector within the LHC at CERN.
    An accomplished researcher, Professor Orr is a Fellow of the American
Physical Society and the winner of a 2006 ORION (Ontario Research and
Innovation Optical Network) Discovery Award of Merit for his work with the
ATLAS Canada group.


    Perimeter Institute is an independent, non-profit research centre where
international scientists are clustering to push the limits of our
understanding of physical laws by contemplating and calculating new ideas
about the very essence of space, time, matter and information. The Institute,
located in Waterloo, also provides a wide array of educational outreach
activities for students, teachers and the general public across Canada and
beyond in order to share the joys of creative inquiry, research, discovery and
innovation. For more information, please visit
