A Science Education 
from A to Z 
From the ABC of Relativity by Bertrand Russell, 
to Zeno’s paradoxes, this 21 -volume library pro- 
vides a complete and fascinating science education. 
Unlike an encyclopedia, this reference work is one 
you can read for pure enjoyment as well as refer to 
for reliable information. The key to this readability 
is the fact that THE REALM OF SCIENCE is ac- 
tually a massive collection of selected writings ar- 
ranged and indexed by subject. It is so complete, 
that the cumulative index alone runs almost 200 
pages! 
Think of a subject, look it up, and read what the 
world’s foremost authorities have written about it. 
The Greatest Minds the 
World Has to Offer 
The authorities represented in this priceless collec- 
tion read like a “Who’s Who” in science. There’s 
Priestley on the discovery of oxygen; Faraday on 
electrochemistry; E.O. Wilson on sociobiology; 
Ernst Nagel on Godel’s proof. Plus Isaac Asimov, 
Jacob Bronowski, Martin Gardner, Max Planck, 
James Watson, George Gamow, Fritz Zwicky, and 
hundreds more. From ancient Babylonia to the pre- 
sent, you will be exposed to the greatest minds the 
world has to offer. 
Einstein’s 
special theory 
of relativity 
changed our 
concept of 
time, distance 
and mass. 
A Valuable Research Tool 
Although each volume contains its own index, the 
unique Science Concept Index “brings it all 
together.” It will help you find vital information on 
a given subject, person, place or idea throughout the 
set. It will also enable you to trace various applica- 
tions of a subject from one author to another, from 
one concept to another, or from one discipline to 
another. Imagine what a valuable research tool this 
can be. Taken as a whole, this 21-volume set pro- 
vides an overview of science never before possible in 
a single work.
