I have been teaching the cosmology of numerology for nearly forty years. Through all of those years I used visual aids, primarily a blackboard with chalk.
On July 30, 2014 I presented the topic for the first time without visual aids when doing the Night-Light radio talk show with Barbara DeLong.
Here is the link to the show. Unfortunately the audio quality is not the best, but the show was well regarded by listeners. You will find the cosmology portion in the first hour, and then it becomes a discussion between the two of us.
Where else can you cover 13 billion years of evolution and numerology in 45 minutes !
