Dr. Stephen Barr talks about modern physics and why modern physics does not conflict with Judeo-Christian theology. His talk is followed by a response from Dr. Alexander Sich. Dr. Barr's talk is a bit dry, but he presents some very interesting information and perspective, at least from my point of view as someone who is interested in physics.
If you haven't read Dr. Barr's book, Modern Physics and Ancient Faith, I recommend it very highly -- he is better as a writer than as a speaker. :-)
