Back-up mass

Ed Parker did a seminar for us in Chicago on April 14, 1981. Two, actually. The first one was 2.5 hours long. We taped it and I still have it. Yesterday, January 15, was the 17th anniversary of my establishing the Ft. Myers studio and we showed the seminar tape to about 20 interested students to mark the day. Kyle Zwarg has since bought the studio but we thought it would be a treat to show it and it was appreciated.
One stand-out point, among many, was that he did not once use the term "back-up mass". The introduction I made before the video was that some of the things he would say would be taken for granted by today's student but in 1981 he was still formulating his terminology. The term he used in the seminar was body momentum. He mentions torque and gravitational marriage by those names but says body momentum instead of back-up mass. It would be later that he would say there were three types of body momentum and list the three, using back-up mass tied into power generated by changes in depth.
The showing of the video actually generated more questions than he did that day in the seminar. He was excited, and it was fun to watch him teach. I miss that guy.
