The Movement of Light as Rolling Balls

4 minutes  • 680 words

To better understand this, imagine that the ball `1234` is pushed from `V` to `X` in a straight line.

Its two sides `1` and `3` descend equally quickly to the surface of the prism `YY`.

`3` makes contact with the prism first. This delays its movement while `1` continues.

This makes the ball roll as `1432`

It is surrounded by four others, `Q, R, S, T` during its descent.

• `Q` and `R` have more force to move towards `C` than `X` has to move towards `B`
• `S` and `T` have less force to move towards `A` than `X` has to move towards `B`
• `Q` presses on `X` through part marked `1` while `S` holds back the part marked `3`
• This increases the rotation of `X`.

`R` and `T` do not harm it because:

• `R` has already left for `C`.
• `T` has not touched it yet.

This explains the action of the `DF` ray.

The opposite happens if:

• `Q` and `R` tend more slowly towards `C` than `X` tends towards `B`.
• `S` and `T` tend stronger towards `A` than `X` tends towards `B`.

In such a case:

• `R` will prevent the rotation of part `1` of `X`
• `T` will prevent that of the part `3`
• `Q` and `S` will not do anything about it.

This explains the action of the blue `EH` ray.

This ball `1234` is very round.

It can easily happen that when it is pressed a little hard by the two `R` and `T`, it goes rotating in another direction instead of stopping its rotation.

Thus, in changing in a moment of situation, it turns afterwards following the order of the numbers `321` because the two `R` and `T` which have made it start to turn away, force it to continue until it has completed a half turn in this direction, and that they can increase its rotation, instead of delaying it.

This has served me to resolve the main of all the difficulties I have had in this matter.

The nature of the colors which appear towards `F` consists only in what the parts of the subtle matter, which transmits the action of light, tend to spin, with more force than to move in a straight line.

Those which tend to turn much stronger, cause the red color, and those which only tend a little stronger, cause the yellow.

On the contrary, the nature of those which are seen towards `H` consists only in what these small parts do not spin as quickly as they are accustomed to when there is no particular cause that prevents them; so that green appears where they do not turn much less quickly, and blue where they turn much less quickly;

And ordinarily at the extremities of this blue there is mixed some incarnate, which giving it liveliness and brilliance, changes it into violet or purple color.

This comes without doubt from the fact that the same cause, which is accustomed to delay the rotation of the parts of the subtle matter, being then strong enough to change the position of some, must increase it in those there, while it decreases that of the others.

For if it is true that the feeling we have of light is caused by the movement or the inclination to move of some matter that touches our eyes

The different movements of this matter causes different feelings in us.

The diversity of our feelings of the fire-aether is seen through colors.

There is nothing in the `MNP` prism that can produce colors, other than how it sends the small particles of the fire-aether towards the `FGH` paper, and from there towards our eyes.

White light and shadow or black, with the colors of the iris which have been explained here, suffice to compose all the others.

I do not agree when the Philosophers say that there are some colors that are true, and others that are only false or apparent.

For all their true nature being only to appear, it seems to me a contradiction, to say that they are false, and that they appear.
