Here we have a triple explanation of three related concepts: The Conservation of Energy, how Waves make the conservation work, and what this has to do (or not) with the frequent sci fi blooper of Sound in Space. All three principles are described with bluescreening, homemade CGI, and pop culture clips you’re sure to recognize. I found out early in making this that the surest way to guarantee your movie is over 8 minutes in length is to swear on the first day that it wont be a second over 3. My last movie was a little on the long side, so I wanted to take it easy and just crank out a few SHORT “Physics in 90 seconds” or something, but the movie ALWAYS has its own ideas (I’ve really known about this phenomenon ever since “Legacy of the Spellmaster” 5 years ago, which also was never intended to be a hair over 3 minutes, and you can go see how that turned out). The situation really is that all these movies are the descendants of original lessons back in my days as a Physics teacher. I am using the original textbook and even the original video clips from a class ten years ago or more (which explains my insistence on using SPACE: Above and Beyond, a show which hasnt seen the light of day in a decade, but was the heart and soul of my original presentation). The clips from Jurassic Park and Battlestar are exactly what I used then, and I guess I’m trying to document everything for posterity. At this point I really have only a few of those “mega” lessons left, one of which involves …
