This site is dedicated to the research of the American engineer Dewey B. Larson (1898-1990). Specifically, it's purpose is to provide a research and discussion mechanism for Larson's works, known collectively as the Reciprocal System of physical theory, or the "RS" theory.

Welcome to the Reciprocal System of theory

The Reciprocal System of physical theory was originally published by Dewey B. Larson in 1959 under the title, The Structure of the Physical Universe. In this work, Larson suggested that the Universe was composed of only one component, motion, a reciprocal relation between space and time where neither could exist without the other. From this premise, he theorized a Universe of Motion which very closely resembles the universe in which we live.

Postal Rate Increases

On May 12th, the Postal shipping rates are going up again. I will update the catalog with new shipping rates at that time. I suspect that we will also have to add a "fuel surcharge" because of the ridiculously high cost of gasoline.

I will also be suspending sales when I leave ISUS HQ until I get back to Colorado and can get set up for shipping again, so if you want any books, NOW is the time to order!

Contact me for priority mail pricing and large order (5+ books) discounts.

PDF Catalog and Flyer in ISUS Block

I have added links to the ISUS/Reciprocal System Flyer (a single, double-sided page that can be tri-folded and mailed) and the current ISUS Catalog to the ISUS "block" on the bottom left side menu. The purpose of this block is to give quick and easy access basic ISUS information for visitors.

Essay VII: The Necessity and Dangers of Thinking Big

...which attempts to pull together some of the main themes of the preceding six essays and to point out the dangers of overes­timating the importance of politics in the lives of men.

Gravitation and the Galaxies

Today, three centuries after Newton, gravitation is still one of the enigmas of science. "It may well be the most fundamental and least understood of the interactions," says Robert H. Dicke. In all of the efforts that have been made to formulate a unified physical theory the big challenge has always been to bring gravitation within the theoretical framework. One of the most basic problems is to define the nature of the phenomenon. According to Einstein's general theory of relativity, the theory that is currently accepted (often with some reservations), gravitation is equivalent to a motion. This assertion implies that, while it has some of the characteristics of motion, it is actually not a motion. The objective of the present discussion is to examine the validity of this conclusion.

On-line Ordering Information

ISUS is currently setting up an eCommerce site to purchase materials online, but having some trouble getting it to work properly. In the meantime, if you wish to order anything from the catalog, you can do so through the PayPal "Send Money" option, which does work with all major credit cards, and International orders.

The current catalog is HERE.

Essay IV: The Individual, the Valued, and the Valuable

...in which it is argued that although an individual's values can be neither rational nor irrational, the individual may be able to change and hopefully improve-his values by a rational process.

1. Since what an individual values is not necessarily what he should value, his value system is potentially improvable.

2. Children acquire their initial set of values from other individuals in their environment.

3. However the fact that some values are acquired from one's environment does not mean that all values are so acquired.

4. Rational change of values is possible, but only with the aid of the individual's present set of values.

5. The "man of action" must assume that his present values are valid.

6. The "man of contemplation" must assume that his present values are at least partially invalid.

No, Dewey has not made a Second Coming to post here

Some people are apparently confused by the "posts" by DB Larson. That is ME doing the posting, not Dewey from the other side. I set up an account on the system for Mr. Larson so that it would track authoring information accurately. That way, when someone searched for articles authored by Larson, they COULD search for Larson, and not have to look under my name. That's all, folks. But if I do figure out how to use the "photon interface" to transmit messages to the other world, you'll be the first to know!

The Nature of Motion

Abstract: Analysis of the data from observation shows that gravita­tion and the recession of the distant galaxies are negative (inward) and positive (outward) scalar motions respectively, and that some other basic physical phenomena not currently recognized as motions are also motions of this same type. Identification of the scalar nature of these motions enables clarification of a number of long-standing issues in physical science.
