DISCLAIMER

The demonstrations and other descriptions of procedures and use of equipment in this book have been compiled from sources believed to be reliable and to represent the best opinion on the subject as of 1990. However, no warranty, guarantee or representation is made by the author as to the correctness or sufficiency of any information herein. The author does not assume any responsibility or liability for the use of the information herein, nor can it be assumed that all necessary warnings and precautionary measures are contained in this publication. Other or additional information or measures may be required or desirable because of particular or exceptional conditions or circumstances, or because of new or changed legislation. Teachers and demonstrators must develop and follow procedures for the safe performance of the demonstrations in accordance with local regulations and requirements.
This preliminary, partial manuscript is a very early, incomplete version of a published book. The much more extensive, heavily illustrated, and up-to-date, full-color, 300-page version was published by the University of Wisconsin Press in 2006 and can be ordered here. You may copy this material for your personal use. Further distribution or commercial use requires permission of the author.
In the matter of physics, the first lessons should contain nothing but what is experimental and interesting to see. A pretty experiment is in itself often more valuable than twenty formulae extracted from our minds.*
