What a Teacher Should Teach

Let us suppose that a certain wise teacher of physics places a

row of Bunsen burners under a long steel bar having a Daniell's

pyrometer at one end, and addresses his class (substantially) as

follows:

"At our last lecture we found that the matter of the universe

permeated all space, but in two conditions, which we agreed to

call physical and etheric, or tangible and intangible. It is all

the same matter, subject to the same laws, but differing in the

rate of vibration, the physical matter vibrating through one

great octave or plane, and the etheric vibrating through another

great octave or plane one degree higher--the chording vibration

of the matter of the two planes in one note producing what we

call energy or force, and with it phenomena.

"This is a bar of steel 36 inches long. It is composed of

physical atoms but no two physical atoms touch. Each physical

atom is as far apart from every other atom as the stars in heaven

from one another--in proportion to their size. The atoms and

the spaces between them are so small to our sight that they seem

to touch. If we had a microscope of sufficient power to reveal

the atom, you would see that no two atoms touch, and that the

spaces between them are, as Faraday says, very great in

proportion to their size. I showed you last term that what

appeared to be a solid stream of water, when magnified and thrown

upon a screen, was merely a succession of independent drops that

did not touch. I can not yet give you proof of the bar of iron

being composed of independent atoms, but that is the fault of our

instruments, and you must take my word for it until the proof is

simplified and made easy of application.

"Each one of these physical atoms is a miniature world. It is

the center of an ocean of ether, composed of many atoms; and

while no two physical atoms touch, their etheric atmospheres do

touch, and any change in the vibration of the etheric atmosphere

of one will be imparted to that of the next. As the vibration of

the physical atom must be in harmony with that of its etheric

atmosphere, any change coming to one will be imparted to the

next, and the next, through the ether surrounding them.

"You can see that the index at the end of the bar has moved,

showing that it is now longer. That means the etheric atoms are

now vibrating faster, taking more space, and have necessarily

forced each physical atom farther apart. The bar is not only

longer, but softer, and as the vibrations increase in rapidity

the time will come when it will bend by its own weight, and even

when it will become a liquid and a gas.

"If you put your hand anywhere near the bar you will feel a

sensation called heat, and say it has become hot. The reason for

that is that you are in actual and literal touch with the bar or

iron through the ether. It is not alone each atom of the bar of

iron that is surrounded by the ether, but each atom of the air,

and each atom of your body. Their etheric atmospheres are all

touching, and the increase in the vibration of the ether

surrounding the atoms of iron is imparted to those of the air

surrounding it, and these in turn raise the rate of vibration in

the etheric atoms surrounding the physical atoms of your hand.

This rate of vibration in your nerves causes a sensation, or

mental impression, you call "heat." Consciousness of it comes

through your sense of touch; but after all it is merely a "rate

of vibration" which your brain recognizes and names.

"The bar has now reached a temperature of about 700 degrees, and

has become a dull red. Why do you say the color has changed, and

why do you say red?

"Because the rate of vibration of the etheric atoms in the bar is

now about 412 trillions per second, and this rate of vibration

having been imparted to the ether of the air, has in turn been

imparted to the ether of your eye, and this rate of vibration in

the ether of the nerves of your eye your brain recognizes and

calls 'red.'

"The heat still continues and increases. You now have both heat

and light. So you see that the ether is not vibrating in a

single note, but in two chording notes, producing light and heat.

There are two kinds of ether around the iron atom. There is

sound also, but the note is too high for one's ears. It is a

chord of three notes.

"Professor Silliman, of Yale, discovered over twenty years ago,

that the ether could be differentiated into the luminiferous, or

light ether, and the sonoriferous, or sound ether.

"Other great scientists since then have found a third ether--the

heat ether.

"Their discoveries show that the atmospheric etheric envelope of

each etheric atom is made up of etheric atoms of different

vibratory powers. As the atmosphere of the earth is made up of

atoms of oxygen and nitrogen and argon, so that of an atom is

made up of three kinds of ethers, corresponding to three of our

senses. That it consists of five ethers, corresponding to our

five senses, as the ancient Hindus assert--who can say?

"I mention this subject of the differentiation of the ether

merely that you may not suppose that the ether is a simple

substance. For the present we will treat it as a simple

substance, but next year we will take it up as a compound one.

"This steel bar before you is not one bar, but two bars. There

is a visible bar and an invisible bar, the visible bar being made

of physical atoms, and the invisible bar of etheric atoms. The

etheric bar is invisible, but it is made of matter, the same as

the visible bar, and it is just as real, just as truly a bar as

the one we see.

"More than this. The etheric, invisible bar is the source and

cause of all phenomena connected with the bar. It is the real

bar, and the one we see is merely the shadow in physical matter

of a real bar. In shape, strength, color, in short, in

everything, it depends on the invisible one. The invisible

dominates, governs, disposes. The visible is merely its

attendant shadow, changing as the invisible, etheric bar changes,

and recording for our senses these invisible changes.

"The invisible change always comes first; the invisible

phenomena invariably precede the visible.

"In all this physical world--in all this universe--there is

nothing, not even a grain of sand or an atom of hydrogen, that is

not as this bar of iron is--the shadow cast on a visible world

by the unknown and mysterious work of an invisible world.

"Land or water, mountain or lake, man or beast, bird or reptile,

cold or heat, light or darkness, all are the reflection in

physical matter of the true and real thing in the invisible and

intangible world about us. "If we have a visible body we have an

invisible one also," said Saint Paul. Modern science has proven

he was right, and that it is the invisible body which is the real

body.

"If this earth and all that it is composed of--land or ocean or

air; man or beast; pyramid or pavement--could be resolved into

the physical atoms composing everything in it or on it created by

God or man, each atom of this dust would be identical physically.

There would not be one kind of atom for iron and another for

oxygen.

"The differentiation between what are called elementary

substances is first made apparent in the molecule or first

combination of the atoms. It is not in the atom itself, unless

it be in the size, as may not be improbable. The atoms combine

in different numbers to make differently shaped molecules, and it

is from this difference in the shape of the molecule that we get

the difference between gold and silver, copper and tin, or oxygen

and hydrogen.

"In all chemical compounds, such as water and alcohol, the

molecules at the base of the two or more substances break up into

their original atoms and form a new molecule composed of all the

atoms in the two or more things combined. To make this chemical

combination we must change the rate of vibration of one or the

other or both until they strike a common chord. As we saw last

term, oxygen and hydrogen have different specific heats, and no

two other elements have the same specific heat, while heat raises

the rate of vibration. Any given amount of heat raises the

vibration of one more than another. Apply heat, and the rate of

one will rise faster than that of the other until they reach a

common chord. Then they fall apart and recombine.

"If we pass a current of electricity through this sealed jar

containing oxygen and hydrogen in mechanical union, the spark

that leaps across the points furnishes the heat, and a drop of

water appears and falls to the bottom. A large portion of the

gases has disappeared. It has been converted into water. What

is left of the gases will expand and fill the bottle.

"The drop of water but for local causes, but for a certain

attraction of the earth, would float in the centre of the jar at

the centre of gravity, as the earth does in space. But the

centre of gravity of the two bodies is far within the earth, and

the drop gets as close to it as it can. The earth's 'pull' takes

it to the bottom. If the jar were far enough away in space the

drop would float, as the earth floats, at a point where all pulls

balance, and the drop of water would have enough pull of its own,

enough gravity within itself to hold all the gas left in the jar

to itself as an atmosphere. It would be a centre of energy, a

minature world.

"The drop of water is not a homogenous mass. About one third of

the bulk of the drop of water is made up of independent oxygen

and hydrogen atoms interspersed through it, as any liquid is

through this piece of blotting paper. And it has, and keeps, by

its own attraction, an atmosphere of the gas. Each molecule of

water has a thin layer, or skin, of the gas; even as it comes

from this faucet.

"Let us return again to the physical dust, the atom. Why should

it form by fives for iron, by nines for hydrogen? Where did the

atom come from? What is it? We know that like the drop of

water, it is a miniature world with an atmosphere of ether; and

the natural inference is that it is made from ether as the drop

of water was made from gas. Many things confirm this inference,

and it may be accepted as 'a working hypothesis' that it is made

from ether as the drop of water is made from gas, by the chemical

union of a large amount of ether of different kinds, the etheric

molecules of which consist of 2 and 3 or 5 and 4 etheric atoms,

and that the tendency to combine in this or that number in

physical matter is an inherited tendency brought with it from the

etheric world of matter on which, or in which, each element of

this world is two or more. There is no kind of matter in this

physical world, that has not its prototype in the etheric, and

the laws of its action and reaction here are laws which it

inherits and brings with it. They are not laws made here. They

are laws of the other world--even as the matter itself is matter

of the other world.

"In 1882, Professor Lodge, in a lecture before the Royal

Institution on 'The Luminiferous Ether' defined it as:

"'One continuous substance, filling all space, which can vibrate

as light, which can be sheared into positive and negative

electricity, which in whirls constitutes matter, and which

transmits by continuity and not impact every action and reaction

of which matter is capable.'

"This reads today like baby-talk but at that time (eighteen years

ago), it was considered by many timid conservative scientists as

'a daring movement.' It is noteworthy in that it was the first

public scientific announcement that the physical matter is a

manifestation or form of the ether. And it was made before

general acceptance of the division of the ether into soniferous,

luminiferous and tangiferous.

"'Which in whirls constitutes matter.' Professor Lodge believed

that 'some etheric molecules revolved so rapidly on their axis

that they could not be penetrated.' Watch the soap-bubbles that

I am blowing. Each and every one is revolving as the earth

revolves, from west to east. What I wish to call your attention

to is the fact that can be proven, both mathematically and

theoretically, that at a certain rate of speed in the revolution

they could not be penetrated by any rifle-ball. At a higher rate

of speed they would be harder than globes of solid chilled steel,

harder even than carbon. Professor Lodge believed that the

etheric molecule revolved so rapidly that, thin as it was in its

shell, it gave us the dust out of which worlds were made. There

is one fatal error in this idea, although it is held even now by

many. It is based entirely on gravity, and gravity is alone

considered in its problems. There are two great forces in the

universe, not one, as many scientific people fail to remember

--Gravity and Apergy, or the centrifugal and centripetal forces.

The pull in is and must be always balanced by the pull out.

There is in the universe as much repulsion as attraction, and the

former is a force quite as important as the latter. The bubble's

speed kept increasing until apergy, the tendency to fly off,

overcame gravity, and it ruptured.

"Professor Lodge failed to take into account this apergic force,

this tendency to fly off, when he gave such high revolutionary

speed to the etheric molecules, a speed in which apergy would

necessarily exceed gravity. The failure to take apergy into

consideration has been the undoing of many physicists.

"Today we know that the ether is matter, the same as our own,

only finer and rarer and in much more rapid vibration. We know

that this ether has its solids, liquids and gases formed from

molecules of its atoms, even as our own are formed. We know that

its atoms combine as ours do, and while we have but eighty

elementary combinations, it must have more than double the

number. We know that every form and shape and combination of

these elements from this plane flows from inherited tendencies

having their root in the etheric world.

"The two worlds are one world--as much at one with ours as the

world of gas about us is at one with our liquids and solids. It

is 'continuity, not impact.' They not only touch everywhere and

in everything, but they are one and the same in action and

reaction."

Thus spake a certain wise teacher of physics. To his wise

utterances, we can only add that such as we are today "we see

through a glass, darkly." Yet there will come a day when the

physical bandages will be removed from our eyes, and we shall see

face to face the beauty and grandeur and glory of this invisible

world, and that in truth it 'transmits by continuity and not

impact every action and reaction of which matter is capable,'

forming one continuous chain of cause and effect, without a link

missing. There are no gulfs to cross; no bridges to be made.

It is here; not there. It is at one with us. And we are at one

with it. One and the same law controls and guides the etheric

atom and the physical atom made from its molecules, whether the

latter are made in "whirls," as at first supposed, or by orderly

combination as now believed.

In fact, this visible world of ours is the perfect product of the

other invisible one, having in it its root and foundation, the

very sap of its life.
