Physics challenged handbook
This is a must read.Bragdon presents, succinctly and simply, the concept of time space within multidimensional terms. A small book and quickly to the points and concepts which are so confusing for the novice in higher physics to grasp. The math is spot on, as are the illustrations. This book will stretch your mind and give a comprehension of the 3-dimensional world and higher dimensions. I found it to have a rather soothing effect on the terrors and doubts of the narrow material world we perceive everyday. It is straight forward logic - no leaps into guessing to make a point. This book has no hidden philosophical, religious agenda - no "cosmic" neo philosophy - no magic or superstition - no leaps of faith - just good, old fashioned analytical science . I have bought many copies over the years, lost them, and acquired more - this should be on everyone's bookshelf, well worn and read.
