Title: very helpful
Review: Easy to read and understand as far as physics go. Confusing typo's in several spots. There was author contact info and I did contact the author to clarify what I felt was a typo that stumped me. He immediately (within hours) contacted me and was very nice, polite and helpful. I also took a course in Las Vegas from this author. Made a very dry subject as interesting as anyone could possibly make it. I passed my MRI exam with a 90%. Thank you Mr. Faulkner.
