**gravity**

THE NEXUS MAGAZINE, pages 4-5, December 1996-January 1997. I am writing to thank you for reviewing a book called "Gravitational Force of the Sun," by Dr. Pari Spolter, in NEXUS, June-July 96 (vol. 3, no.4). I bought the book to find out how to calculate the gravitational force of celestial bodies, for a project I'm working on, thinking it would be a well-understood and thoroughly documented area of research beyond controversy-more fool I! Dr. Spolter exposes the fundamental mathematical errors in both Einsteinian and Newtonian theory with such elegance and ease that even a mathematical recalcitrant like myself was inspired to recall my high-school mathematics (last used in anger 20 years ago!) to follow her working out. No, I am not making this up: I voluntarily engaged in strenuous mathematics for my own enjoyment! "Gravitational Force of the Sun" is very focused. Dr. Spolter successfully knocks the pins from under two great, unchallenged theories of science by reviewing the original documents that Newton wrote and examining the mathematics and assumptions that Einstein and Newton used. I have seldom before read a more thorough hatchet job. She must be a relentless researcher with prodigious memory and intellect. The book is not negative. Dr. Spolter shows Kepler's contributions to be far greater than I previously suspected (Kepler's work is the foundation she builds her work on), and what she tears down she rebuilds. With this book I can go forward in my project: without it I would be doomed to failure. Thank you, Dr. Spolter, and thank you, NEXUS. Regards, Paul M., Sydney, NSW, Australia.
