Where's the Physics?
I was hoping this video would excite my 14-year-old son about Physics. Unfortunately there's only the most token, and I mean token, mention of the physics of a roller coaster. This title is just plain deception. My son remarked that it seemed like an info-mercial for various roller coasters. I heartily agree. The Discovery Channel should be ashamed.
