John William (J.W.) Carr served a lifelong career as a research specialist and electrical engineer, including almost 28 years at Lockheed Missiles & Space Company and Boeing Corporation. Also known as 'Bill' Carr, he was a renowned and acknowledged master designer of antennas and RF components in the national defense industry.

Bill Carr died on September 8, 1992, before he was able to publish his book, The Physics of Electromagnetic Masses, Including the Derivation of E=mc2 from a Point Source, in which he made a major breakthrough in the study of electromagnetic radiation and applied electromagnetic theory (e.m. theory).

On his deathbed, Carr gave his daughter, Helen, his book to publish so that his findings could be shared with the world. Out of love for her father, Helen Carr recently has published the book and released the first printing. "I have to set the record right for my father once and for all", Helen said, breathing a sigh of relief.

Carr demonstrates how all electromagnetic particles and fundamental building blocks of matter have mass, including what we call neutrinos, light, and energy. Refraining from giving yet another trendy name for the same thing - the fundamental building blocks of electromagnetic radiation - Carr purposely chose to give these fundamental building blocks a very basic, generic name: electromagnetic masses. If something does not appear to have mass to us, it is because we have not used the correct means to detect it.

In his book, Carr totally overhauls modern e.m. theory and derives an entirely new set of mathematical formulations to replace those currently in use, which electrical engineers and physicists must use to design antennas. Antennas are required for everything from radio signal transmission and reception, television signal transmission and reception, radar systems, navigational position-finding systems, submarine sensor devices, instrument landing systems, and deep-space signal transmission and reception, to guided nuclear missile systems. Electromagnetic radiation affects every one of us in our daily lives, one way or another.

Electromagnetic radiation is the propagation of energy through space by means of electric and magnetic fields that vary in time. According to electromagnetic theory, in electromagnetic radiation a periodically varying electric field is accompanied by a magnetic field, and vice versa. The electric and magnetic fields in an electromagnetic wave act in planes that are perpendicular to each other, and perpendicular to the direction of propagation. As electromagnetic radiation propagates in free space (in the absence of a material medium), it travels at the speed of light - the universal constant c - or about 186,000 miles per second.

Electromagnetic radiation may be characterized by wavelength, or the frequency with which it varies in time. The electromagnetic spectrum represents all forms of electromagnetic radiation, which have been arranged according to their wavelength, or frequency of oscillation. The various wavelengths or frequencies of electromagnetic radiation in the electromagnetic spectrum each interact differently with matter.

The most familiar wavelength or frequency range is light - that narrow bandwidth of electromagnetic radiation frequencies which our eyes can see. Other wavelengths or frequencies of electromagnetic radiation include cosmic ray photons, gamma rays, x-rays, ultraviolet, infrared, microwaves, radar, UHF, VHF, FM shortwave, AM radio, and longwave radio.

Different types of electromagnetic radiation can be manmade by changing the frequency of oscillation at the source-radiating antenna. For example, microwaves developed for radar in World War II were small in comparison to radio waves, because they had a shorter wavelength than radio waves, or a higher frequency of oscillation.

In addition to wave-like motion, electromagnetic radiation also has particle-like properties, in which each particle is referred to as a quantum of electromagnetic energy, or photon.

Albert Einstein demonstrated theoretically from out in space that E=mc2. Carr also derives E=mc2, but from a point source or point of origin. This finding is unprecedented. It is important to note that first Carr had to rewrite modern e.m. theory in order to get there.

In so doing, Carr correlates the four equal parts of energy with Einstein: the three inertial, kinetic-energy parts of electro-mechanical energy, along with the one necessary gravitational (potential energy) part that holds these electromagnetic masses together and provides a reaction force (Newton's third law).

The unified field theory states that there is a relation between gravitational fields and electromagnetic radiation. Einstein believed that we should be able to represent the whole of all physical reality not by individual particles, but by means of a field, so that matter or material things as we know them would be nothing more than a region of high field intensity. The general theory of relativity is essentially a field theory that also includes the concept of a particle. In the unified field theory, this would not be the case --- everything would be described in terms of a field, never a particle.

What Carr proposes in his book supports the plausibility of a unified field theory.

Currently, physical models and mathematical formulations that are used in modern electromagnetic theory for working with electromagnetic radiation often do not jibe with what is measured in the field or the laboratory.

In his book, Carr first explains why current theories and mathematical formulations are wrong in modern e.m. theory, then unveils a dynamic physical fluid model for electromagnetic radiation as it moves from a point of origin out into free space, and derives an entirely new set of working mathematical formulations for electrical engineers and physicists to use in their daily lives for measuring electromagnetic radiation and designing antennas.

What Carr proposes is quite controversial, because in his book he asks an entire industry to "wipe the slate clean" in order to understand finally what they have been doing wrong all of these years. No longer will an electrical engineer or physicist have to try to patch up "unexplained phenomena" with mathematical equations in which the physical dynamics of a situation are not considered, as is currently the case in the industry today, according to Carr.

This book is not purely theoretical --- all theories and mathematical formulations are substantiated by sound, scientifically based, laboratory experimentation.

Like everyone else in the field of electrical engineering and antenna design has been doing in e.m. theory for generations, self-admittedly, Carr too spent the majority of his working career doing what he referred to as "parroting" --- even if it did not make dynamic physical sense. No matter how absurd a formula was, he used it as long as it provided a short-term, "band-aid" cure for the problem at hand in his daily work. It was not until Carr stopped accepting such formulations that did not match what he measured in the laboratory that he went on to overhaul modern e.m. theory in electrical engineering and antenna design.

Many readers who are electrical engineers or physicists will not be able to grasp what Carr is saying, if they give the book nothing more than a cursory overview. In his book Carr asks his colleagues to learn an entirely new approach for problem solving in the industry. It will take time for those who are open-minded to read, understand, and use Carr's theories and mathematical formulations in their work.

Food for thought: shortly after Carr retired, he was asked to come back out of retirement to work again in the national defense industry, and figure out a solution to a problem that no one in the industry had been able to solve. Guess what? He solved the problem!

Carr clearly shares with the reader his line of reasoning that made possible solutions to problems in e.m. theory heretofore unresolved in the field of electrical engineering and antenna design. Although a background in e.m. theory is helpful, anyone with a basic understanding of physics and calculus can glean the highlights from this book.

It was Bill Carr's hope that by sharing his findings, others would be able to make further advancements in science for the good of all.
