"An ambitious new treatise on the otherwise seasoned subjects of Space & Time. We are not qualified to evaluate it, but are pleased to see it in this ('comic book') format." - THE WHOLE EARTH CATALOGUE, Portola Institute, 1970 - ‘71
"An unprecedented and awesomely credible non-mathematical theory which matter-of-factly proves that gravity is the 4th dimension of time, then forthwith discovers the previously unrecognized - therefore unidentified - 5th & 6th dimensions of electricity and magnetism."
- Dr. John Shaw, Chemistry Prof. 1971, University Of California @ Berkeley
"Gravity Is The 4th Dimension' - A documentary scientific 'Future Shock'. Major conceptual breakthrough. It must be disqualified or formally acknowledged at the foundations of modern theoretical physics; there is no middle ground. So advanced it's simple."
- Mark Vukovic, Electronics Tech, U.S.N. USS Shasta (AE-33), San Francisco, CA.
"This book has clearly made a formerly mystified theoretical physics truly comprehensible to anyone with high school reading skills and 'street people' in general. Beyond its overt revolutionary scientific import, the social implications are also profound. Bound to surprise and constructively inf luence an enormous number of people for a very long time. Ignoring or denying it won't make it go away. Now I know what E=MC squared means."
- Don Donahue, original printer and publisher of ZAP Comix, San Francisco
"Gravity really is the 4th dimension, and levity and mirth use to be the 5th and 6th dimensions, until K.B. Robertson found them to be electricity & magnetism, respectively. - Herb Caen, The San Francisco CHRONICLE
"Not without levity, the sharp shooting author expertly documents his academic and historical subject; then - suddenly - the reader is experientially surrounded by it. There is no intellectual escape from the 4-D space-time continuum anymore, in or out of an ignorant or uninterested yawn. The very act of reading these words is directly and physically sustained by it. Observing various responses of others, in the early stages of recognizing it, is a recreation in itself. The documentary is scientifically irreproachable, the informal narrative is a social liberation. The inveterate elements don't like it already."
- Sallie Taylor Melinda Bryan, 1979
"Academic L.S.D. in a Stockholm punchbowl, and everybody's invited. Ready or not there is no way out of this but through it. A scientific Odyssey. The most remarkable fact about 'The New Gravity' is that it was not discovered and written much earlier."
- Gregory Nageotte, Ph.D. Philosophy, Santa Barbara, CA. 1979
"I am unable to disqualify it."
- Dr. Richard Feynman, 1966, Professor Emeritus, Cal Tech
"It reads a hell of a lot more easily and comprehensively than anything else of the subject of Einstein's Relativity. Reads at least as easily as the brass tacks section of any good sci. fi. mag., and it is not science fiction."
- Travis T. Hipp, KSAN radio, San Francisco, 1970
"The old saw, 'There is no gravity, the earth sucks', is no longer tractable. The New Gravity (Is The 4th Dimension) is the old gravity, in a pushy new paradigm of Einstein's 4 dimensional space-time continuum. Guaranteed to illuminate even the most diffident mind. It will chancelessly see you and raise you indefinitely. The New Gravity will never let you down."
- Arthur Kretchmer, 1979, Article Editor, PLAYBOY Magazine
'Is gravity really the 4th dimension? Or has the author only cleverly built his theory around reality so that no one can tell the difference? '
