Modern physics is potentially the richest, most fascinating and thought-provoking part of a high school student's exposure to the wonders and mysteries of our universe. To help teachers achieve this potential, Perimeter Institute for Theoretical Physics has designed an international teachers' workshop. The Einstein Plus program was created by physicists at Perimeter Institute in conjunction with local and regional professional educators. http://pirsa.org/podcast/C07018 Science 2009 http://blogs.law.harvard.edu/tech/rss en-ca Thu, 08 Jan 2009 07:00:37 -0500 sbradwell@perimeterinstitute.ca Thu, 08 Jan 2009 07:00:37 -0500 G 180 pirsa-admin@perimeterinstitute.ca Steve Bradwell's - Podcast Generator One simple way to think about physics is in terms of information. We gain information about physical systems by observing them, and with luck this data allows us to predict what they will do next. Quantum mechanics doesn't just change the rules about how physical objects behave - it changes the rules about how information behaves. In this talk we explore what quantum information is, and how strangely it differs from our intuitions. In particular we see how information about quantum particles can become entangled, leading to seemingly impossibly coordinated behaviour for separate objects.

Quantum mechanics rules, allowing atoms to be, in some sense, in more than one place at a time. Researchers all over the world are working to build "quantum computers" whose memories manipulate an inherently new type of information, "quantum information." Quantum computers have capabilities impossible for a regular computer, no matter how advanced it may be, including the ability to run new kinds of computer programs capable of rapidly solving certain problems, and to make new highly secure codes for secret communication.

Some simple mathematical arguments are included. This leads to a brief description of Loop Quantum Gravity - one of the most popular way of trying to describe gravity using the ideas of quantum mechanics. In addition, the Standard model of particle physics, which describes all known particles and their (non-gravitational) interactions is explained. We conclude with a description of some recent research which may bring the Standard Model and Loop Quantum Gravity together into a single theory.

In the past five years, this suspicion has become a certainty. We now know for sure that normal matter and normal radiation account for only 4% of the density of the universe. One of the two biggest components, dark matter, may be finally be identified by new experiments coming on line next year. I'll summarise the long quest to identify dark matter and our prospects for finally achieving this goal in the next two years.
