Another story of 4D from Miles Breuer, this time with Prof. Cosgrave who builds a "hyperstereoscope" that can combine 3dimensional views ("geometrical stereograms") from different angles into a 4D composite using the extended holographic principle. With his instrument, he finds out that Total Reality is like a book, with each page reflecting the stages of the universe's evolution, including the rise of organic life. On finding that our future evolution dooms us to an inevitable, selfdestructive war, he goes mad. Written in a very skimming, peremptory style, especially the teleologic description of our pessimistic fate.
There are quite a few pithy lines scattered in the story,
"I worked out the mathematics of a very ingenious instrument for integrating light rays from two directions into one composite beam"
"Points on the adjacent leaves of a book are far apart, considered twodimensionally. But with the book closed, and to a three dimensional perception which can see ACROSS from one page to another, the two points are very near together"
and one unusual line for most stories back then:
[Professor's assistant mathematician]: "he asked me to work out the equations for the projection of a tesseracoid: c1*w^4 + c2*x^4 + c3*y^4 + c4*z^4 = k^4 from eight different directions, each opposing pair of right angles to the other three pairs. Most of the problems he gave me were projection problems."
