The narrative explains Einstein's reasons for linking energy, mass, and the speed of light; why the speed of light is squared; and what the equals sign really means. A brief look at general relativity completes the book.

The general reader is the intended audience, and if the notes section is read along with the main text, the reader will gain a decent nontechnical understanding of the equation. Well-placed diagrams in the main text would have added much clarity. Today, 'dark energy' and 'dark matter' are spoken of as if they were two different 'things'.

Some even hypothesize that the universe was filled with pure energy before it became filled with matter. This estrangement between matter and motion separability is common in popular culture and underlies the 20 th century regression from realism to idealism in modern physics. Without it, it is impossible to explain the physical meaning of the equation.

The experimental success of the equation led to the increasing objectification of energy. However, being a matter-motion term like momentum and force, energy neither exists, nor does it move.

It is simply an idea, a concept, a mathematical description of the motion of matter. Matter does not 'contain' energy, for matter only can 'contain' other things in motion. Energy is simply a mathematical term necessary for describing and relating the various forms of the motion of matter. Unfortunately, the derivation is repeated today as being correct without any mention of the above criticisms of it.

Einstein's derivation of mass-energy equivalence is philosophically impor tant because it contains both a criticism of purported demonstrations that proceed by analogy and strong motivations for the definitions of the 'new' dynamical quantities viz relativistic momentum, relativistic kinetic energy and relativistic energy. Along the way, I isolate three distinct physical claims associated with Einstein's famous equation that are some times not clearly distinguished in philosophical discussions of spacetime theory.

With the first of these sentences, concerning the fame of Albert Einstein's equation, it is difficult to disagree.

But the second sentence, which characterizes mass and energy as interconvertible and "two forms of the same thing," suggests that some care will need to be exercised in interpreting the famous equation. Indeed, it is difficult to find a scientific equation whose ontological implications have been misunderstood so widely and in so many ways.

I shall begin by looking at some of the issues that arise when interpreting the famous equation. Along the way, I shall examine briefly some of the ways in which one could become confused by the equation's common interpretations-not only in ordinary physics texts, but also by some very distinguished physicists and philosophers. I shall then try to set the record straight.

If, despite the aid and comfort of these gracious people, I have made any errors, they are entirely my fault, and I thank the vigilant readers who will surely set me straight. It can rightly be said that modern physics started with Albert Einstein whose legacy will stay with us for a long time to come. The equation that bears his name is as famous as Einstein himself.

Indeed, the equation has been immortalized by its utter simplicity and its profound meaning and impact in our civilization. The energy E of a body at rest is equal to its mass 'm' multiplied by c 2 that is c x cwhere 'c' equals the speed of light in vacuum. The equation's message is that the mass and energy of a body are convertible, and the mass of a body measures its energy content.
