Physics

Newton’s discovery of the universal law of gravitation was the culminating moment of the scientific revolution, Man’s closest glimpse into the Mind of God. It is said that the apple fell to Newton from the Tree of Knowledge in the Garden of Eden itself.

“Normal adults don’t stop to think about such concepts as space and time. These are things children ask about. My secret is I remained a child. I always ask the simplest questions. I ask them still.” — Einstein

That quote comes to my mind especially today, reading the headline: “Discovery of New Particle Could Redefine World”

So let us be like children now, just for a moment, and take time to think a bit about time, and space, and everything…

Fun with Electricity

We always talk of matter as if it only had passing relation to electrical effects. Yet if we look in detail into the nature of matter, we find physical substances, made of molecules, made of atoms, made of positive and negative electric charge. Matter is not electrical? No, quite the opposite: electric charge is the major component of all atoms. Therefore matter is *made out of cancelled electric charge.* If we cancel out some opposite charge by placing positive charge together with negative charge, do we get NOTHING? No, instead we get material substance. Positive protons plus negative electrons equals neutral atoms. Physical objects normally have no charge? Wrong. The physical objects *are* the charge.

I believe the answer given by Paul Walorski here http://www.physlink.com/education/askexperts/ae86.cfm is incorrect in the statement, “The polarization of the first observed photon can be interpreted as nothing more than the measurement of a characteristic that was established back at the time both photons were created.” If it were true that “nothing more” than this is [more …]

An electron is a physical condensation of the electromagnetic field that permeates all of spacetime. Thus every electron has the same source. The electron is like the morning dew, appearing from and returning to “the thin air.” — Photons are not massless in a superconductor. They are heavy. Electromagnetic radiation does not penetrate superconductors. If [more …]

Light and energy, gravity and inertia; these are material mysteries. We cannot explain them. A mystery is not the same as a puzzle. A puzzle can be figured out. A mystery, in the religious sense, cannot. A mystery cannot be figured out, because it defies figuring. We have literally taken lightening out of the sky and made it to sing, yet in a very real sense, we have no real knowledge of it all.

What is a fundamental? Something that is not derived. Something that cannot be explained in terms of something else. For example, our understanding holds the following to be fundamentals: mass, length, time, energy, force, charge… We have trouble really understanding these, because understanding is done through analogy and definitions. Normal definitions are based upon deeper [more …]

Heat and Light

Now, you may say that this is all metaphorical, to say that this thing is actually another, and you would be absolutely right. Metaphor is exactly that: an expression that equates two seemingly different things. In other words, mathematics. The equations of physics that describe the universe are metaphors that tell us that this equals that. E=MC2 is the mathematical metaphor that tells is that matter IS energy. We know that space is not separate from time, and yet we speak of time as if it flows through space. This is not correct. Neither is it correct to speak of light and radio as if these are two different phenomena. They are not.

Gauss said that if the truth of this formula is not immediately apparent to you, you will never be a top notch mathematician.

Even for those of us who do not immediately see the truth of this formula, we can nevertheless recognize the breathtaking beauty of an equation that relates so many fundamentals: zero, one, addition, multiplication, exponents, pi, i, and e. Truly staggering! And here’s a video explaining it…

Quantum Entanglement is THE mystery in physics. Entanglement is the thing that makes the quantum world, “different”. It is what is behind the two slit paradox.

I sought the fount of fire in hollow reed
Hid privily, a measureless resource
For man, and mighty teacher of all arts

The glancing eye of fire, dim before,
And made its meaning plain. These are my works.

What thou wouldst learn I will make clear to thee,
Not weaving subtleties, but simple sooth
Unfolding as the mouth should speak to friends.
I am Prometheus, giver of fire to mortals.

The one thing you have to always remember is that every interaction in the universe is the result of physical touch. All of our senses are touch. One physical thing touching another. There is no force outside of this. There is only one object touching another object.

Even our sight is nothing more than our experience of the physical objects of the world emitting photons (which are physical particles) which then physically touch and are absorbed by the electrons in our retinas. Even sight is touch.
