In this episode, my guest is Dr Mark Lopes.  We will be talking about science, and especially how it effects the field of radiology.  Dr Lopes recently completed a project to create an app that would solve a common criticism that has been leveled against Gonstead chiropractic.  Instead of ignoring the complaint, he chose to address it and solve it.  Join us as we discuss that and many other issues related to our scientific understanding of x-rays.
