Before the Big Bang? Sir Roger Penrose to share the latest theories at Perimeter Institute Public Lecture

    WATERLOO, ON, Sept. 29 /CNW/ - Sir Roger Penrose, prominent lecturer and
author, as well as highly distinguished mathematician and theoretical
physicist, will give Perimeter Institute's next public lecture on Wednesday,
October 1.
    There is now a great deal of evidence confirming the existence of a very
hot and dense early stage of the universe. Much of this data comes from a
detailed study of the cosmic microwave background (CMB) - radiation from the
early universe that was most recently measured by NASA's WMAP satellite.
    But the information presents new puzzles for scientists. One of the most
blatant examples is an apparent paradox related to the second law of
thermodynamics. Although some have argued that the hypothesis of inflationary
cosmology solves some of the puzzles, profound issues remain.
    At this event, Prof. Penrose, in his approachable and engaging style,
will describe a very different proposal, one that suggests a succession of
universes prior to our own. He will also present a recent analysis of the CMB
data that has a profound bearing on these issues.


    Sir Roger Penrose is currently emeritus Rouse Ball Professor of
Mathematics at Oxford University. His research interests span many aspects of
geometry, having made contributions to the theory of non-periodic tilings
("Penrose tilings"), to general relativity theory and quantum foundations. He
has also had remarkable insights in the science of consciousness. His main
research programme is to develop the theory of twistors, which he originated
over 30 years ago as an attempt to unite Einstein's theory of general
relativity with quantum mechanics.
    Penrose's 1989 book The Emperor's New Mind became a best seller and won
the 1990 (now Rhone-Poulenc) Science Book Prize. His other books are Road to
Reality (2004), The Large, the Small and the Human Mind (1997), The Nature of
Space and Time (1996), with Stephen Hawking, and Shadows of the Mind (1994).
    In 1994 Professor Penrose was knighted by Queen Elizabeth II for his
service to science. He has received numerous prizes and awards, including the
1988 Wolf Prize, which he shared with Stephen Hawking for their understanding
of the universe, the Dannie Heinemann Prize, the Royal Society Royal Medal,
the Dirac Medal and the Albert Einstein prize to name a few.


    Canada's Perimeter Institute for Theoretical Physics is an independent,
non-profit, scientific research and educational outreach organization where
international scientists cluster to push the limits of our understanding of
physical laws and develop new ideas about the very essence of space, time,
matter and information. The award-winning research centre provides a
multi-disciplinary environment to foster research in areas of Cosmology,
Particle Physics, Quantum Foundations, Quantum Gravity, Quantum Information,
Superstring Theory, and related areas. The Institute, located in Waterloo,
Ontario, also provides a wide array of educational outreach activities for
students, teachers and members of the general public in order to share the joy
of scientific research, discovery and innovation. In partnership with the
Governments of Ontario and Canada, Perimeter Institute continues to be a
successful example of private and public collaboration in science research and
education. More details are available at
