SEVEN IDEAS THAT SHOOK THE UNIVERSE
by Nathan Spielberg and Bryon D. Anderson, 1987
PREFACE (pvii-viii)
1) INTRODUCTION --- "Matter and motion --- the continuing scientific revolution" (p1-13)
[1] Revolutions and science (p1-3)
[2] Dominant themes in physics (p3-4)
[3] Continuing evolution of scientific knowledge --- the seven ideas (p4-8)
Scientific knowledge is based on experiments by people not given in one awe-inspiring moment. There will always be more experiments that can be carried out to increase the amount of scientific knowledge available to human beings.
The cumulative result of these experiments may be the perception of new patterns in the store of scientific knowledge or the recognition that patterns which had once been thought to be all-embracing were not so universal after all.
It is the ongoing turmoil and upset --- revision and updating when established ideas are overthrown or greatly modified as new and different patterns of phenomena are recognized --- that produced the seven major scientific conceptions or ideas of physics discussed in this book.
A brief review of the ideas will indicate their major themes:
(1) The planet Earth is not the center of the universe --- Copernican astronomy (p4)
(2) The awesome universe is a mechanism that operates according to well-established rules --- Newtonian physics (p4-5)
(3) Energy drives the mechanism --- the energy concept (p5)
(4) The mechanism runs in a specific direction --- entropy and probability (p6)
(5) The facts are relative, but the law is absolute --- relativity! (p6)
(6) You can't predict or know everything --- qauantum theory and the limits of causality (p6-7)
(7) Fundamentally, things never change --- conservation principles and symmetries (p7-8)
[4] Physics without mathematics? (p8-9)
[5] Science and other areas of human endeavor --- distinctions and similarities (p10-13)
This revolutionary idea contradicts the common notion that all things must change. The idea is still being developed by scientists. Its full range of implications is not yet clear.
