El Monte, CA: Understanding Publishing Co., 1956. First edition (no additional printings stated). 83pp. One dog-eared corner; light toning to textblock edges. Jacket with chipping to spine ends, and insect loss along flap hinges (mostly rear). Very good in a good jacket, whose attractive Ralph R. Huffman design still presents well. Signed by Fry to front endpaper.
Uncommon first edition of this work of theoretical physics by the author of The White Sands Incident (1954) and other UFO-related titles; purports to "dissolve a few of the artificial barriers to progress which have been raised by our purely mathematical approach to the laws or facts of the universe." UFOS are only mentioned in passing here, though his subject matter certainly remains closely related. Foreword by Lloyd E. Cannon. Rasmussen 389.
