Einsteins Question

So to Galileo's proposition that no observer can use his own experiments to determine whether he is in absolute motion or at absolute rest, Newton added the proposition that no observer can use another observer's experiments to make the same determination. The sailor sees Newton's experiment deformed in the same way that Newton sees an identical experiment performed by the sailor deformed. The only motion that the two observers can detect is the relative motion between them. What happens when two observers look at the same experiment?

Imagine that we have set up a large powerful magnet and that we have suspended an electrically charged thread next to one of the magnet's pole faces so that the thread passes over the center of the pole face. We then accelerate the thread to a very high speed in the direction parallel to the direction in which we have it stretched.

In the laboratory of our imaginations we also have two observers: Markus Torvaldsen stands next to the magnet and Torvald Markussen moves with the thread. In accordance with Newton's third law of motion, the magnet must also exert a force upon the thread. Instead of passing directly over the center of the magnet's pole face, then, the thread will pass over an array of points comprising a curve that passes to one side of the center.

Torvald must also see the thread curve past the center of the magnet 's pole face, so he also infers the existence of a force acting on the thread. But he doesn't see the thread as an electric current, so he must infer that the moving magnet generates an electric field that will exert the appropriate force upon the static charge on the thread.

From that inference he could deduce the law of electromagnetic induction, but we don't want to follow that path here. Both observers see the effect of a force pushing on the thread, but they offer different explanations for what generates the force.

Zebra Puzzle

If our observers conduct this experiment many times, with many variations in its parameters, they will accumulate enough data to enable them to infer the rules describing the relationship between the force exerted between the magnet and the thread and the parameters of the system. In this case our observers obtain a rule for calculating the force on the thread, which rule includes, in addition to the multiplications and divisions by various constants and geometric factors, the product of the magnet's field strength, the electric charge on a unit length of the thread, and the velocity between the magnet and the thread.

In Markus' case, the velocity multiplies the electric charge to yield a description of the electric current interacting with the magnet's field and in Torvald's case, the velocity multiplies the magnet's field strength to yield a description of the electric field acting on the charged thread. The difference between Markus' and Torvald's descriptions of the cause of the force on the thread thus boils down to the difference between A BC and AB C. Thus, when our observers break their descriptions of the force into its most fundamental components, they discover that the law governing the force is the same for both of them.

Thus we see Einstein's version of the principle of relativity: I will just note here in this regard that Einstein began his paper "On the Electrodynamics of Moving Bodies" with a description of an imaginary experiment similar to the one I described above. Einstein's analysis requires a greater subtlety of interpretation, but it leads to the same postulate. Einstein also knew Maxwell's Equations and the electromagnetic theory that physicists had organized around them. Our modern theory of light as an electromagnetic wave comes from those equations, so the Maxwellian theory of electricity and magnetism necessarily played a role in Einstein's approach to his question.

Imagine that Einstein's friend Besso operates a machine that generates and projects the ray of light that Einstein wants to pace. He arranges to project the ray along his and Einstein's common x-axis in such a way that the ray's electric field points only in the y-direction and the ray's magnetic field points only in the z-direction.

As the ray emerges from the projector Einstein takes off after it and paces it. Besso measures the strength of the ray's electric and magnetic fields at several points on the x-axis at different times. Those measurements tell him that at any given point the strengths of both fields change in a sinusoidal way with the elapse of time and that at any given time the strengths of both fields change in a sinusoidal way with a change in location.

From those data Besso could derive Faraday's law of electromagnetic induction and the form of Ampere's law that we might call Maxwell's law of magnetoelectric induction. Einstein makes the same set of measurements. Those measurements tell him that at any given instant the strengths of both fields change with a change in location, but at any given point that is stationary relative to him the strengths of both fields remain unchanged with the elapse of time assuming, of course, that he experiences time as a Newtonian absolute.

Like Besso, Einstein can extract from those measurements an abstraction describing each field as a sinusoidal pattern in space. But unlike Besso, he cannot derive Faraday's law or Maxwell's version of Ampere's law from his data because those data do not include temporal changes in the fields. Apparently Maxwell's Equations do not exist for Einstein as they do for Besso. On first impression, though, that interpretation seems to violate Einstein' s version of the principle of relativity. When Besso derives Faraday's law from his data, for example, he gets.

If we actually had Faraday ' s law as. In Reality Einstein didn 't follow that path. He approached the problem instead by proceeding as if the time derivatives in Maxwell's Equations are not convective derivatives, but are perfect, unaltered partial derivatives. That assumption necessitates that everyone observing the ray from Besso's projector must see the fields at any given point changing with the elapse of time.

At this point I must note that the motion of light is an illusion.

Einstein's riddle

Light does not move: That is, when, at any given point, the strength of one of the fields rises or falls it induces the strength of the field at neighboring points to rise or fall in such a way that the curl of the field remains consistent with the associated rate at which the strength of the other field changes with the elapse of time. In order for light to exist for an observer, then, the fields must change inherently with the elapse of time; they cannot appear static.

That proposition being true to Reality necessitates that Besso observe the situation in such a way that he can only infer that the ray propagates past Einstein. Did God create everything that exists? The student became quiet before such an answer.

The Answer

The professor was quite pleased with himself and boasted to the students that he had proven once more that the Christian faith was a myth. Of course it exists. Have you never been cold?

According to the laws of physics, what we consider cold is in reality the absence of heat. Every body or object is susceptible to study when it has or transmits energy, and heat is what makes a body or matter have or transmit energy. Absolute zero degrees F is the total absence of heat; all matter becomes inert and incapable of reaction at that temperature. Cold does not exist. We have created this word to describe how we feel if we have no heat.

Darkness is in reality the absence of light. Light we can study, but not darkness. You cannot measure darkness. A simple ray of light can break into a world of darkness and illuminate it. How can you know how dark a certain space is?

Einstein's Question

You measure the amount of light present. Darkness is a term used by man to describe what happens when there is no light present. We see it every day.

It is in the multitude of crime and violence everywhere in the world. These manifestations are nothing else but evil. Evil is simply the absence of God. It is just like darkness and cold, a word that man has created to describe the absence of God.

God did not create evil. What we do not understand is the impressions or tendencies we create in the subconscious mind by those actions create neural pathways that hunger for more of the same. So it behooves us to be observant of our perspective and the mode or concept our view of the world is. What we do not understand is the impressions or tendencies become habitualized in the subconscious mind by our actions creating neural pathways that hunger for more of the same. There is nothing outside of us that has greater power than the Divine potential within.

If we can truly believe this, our view of the world will not falter on safety and security. Our energy, focus, and will may ignite the fire of love and light to glorify God by becoming and fulfilling our divine potential. Your email address will not be published.
