1987-1990. 210p. Deluxe Quarto Hardcover Facsimile Edition. Maroon Suede w/Guilt Lettering. For the past 15 years, the only resource that has been publicly available to convey Jerry BaumringÃ•s thoughts were the Lecture Notes of Julius Nirenstein. We have now discovered another set of equally excellent notes by Al Friedman. AlÃ•s Notes are almost as detailed and extensive as JuliusÃ• Notes but contain variations on coverage and presentation in many details, being just over 200 pages to JuliusÃ• 250. It is evident just by scanning them that there are many important elaborations, clues and details in these notes that will fill in holes in understanding BaumringÃ•s thought, and that together with JuliusÃ• Notes, they will give us a clearer and more elaborate understanding of the Law of Vibration.
