im grasping..george's..camera...simulation..[i think]

if only seen from the camera..view..
there is first the image.[or rather the light..reflected from the image]

that passes..its refractive and reflective photons..
though..say a polarizing..lens/to reduce some of the scattered..[refractive photons]

leaving the reflective..photons..passing though the
..focus and other lenses../or other filter's

then the aperture...to the film

[in this case..i substituted..the polarizing lens..for georges..angular lens]..not sure if polarization lens would nullify the triangular peephole lens..thingy..[by which we observe the focus/framing of the photo's composition


if not..then..via the 45%..refractive thingy..[which captures the refractive photons..NOT the direct..[polarized]..reflective potons..moving though it..to the flim

so 1 =image's..emitted photons

two=the re-direction of some of..
the not direct..line of sight photons..[ie some of refractive photons]

3..[ignoring the other photon filtering/modifying/mechanisms..the photons captured on film...

the issue of lights variable components..has long confounded science..with the speed of light..not being constant

does..for example
red blue ultraviolet infrared light
heat sound particles..ultra sound etc..all moving in waves..*
yet do..they all move [vibrate]..at the same speed..[my opinion..no they dont]

im know im over thinking this

but as my mind isnt visualizing..it*..[ie forming an image of it]....
thus my brain isnt seeing it...

never the less
i see im over-thinking it
not over trying to grasp it....ok..lets examine my mind..as a trinity

ok i get it..we sometimes add..too many filters

Dear Banjo,

Newton’s laws are excellent mathematical models of what happens with moving bodies. Like other mathematical models they approximate reality but are an abstraction which does not fully reflect reality. In an actual physical collision between billiard balls an action will not have an equal and opposite reaction only a close approximation to one. Unlike ideal billiard balls real billiard balls are not completely elastic. Momentum is not preserved. Some of it will be lost in friction. In any macroscopic act in the real world entropy will increase. When we are introduced to Newton’s laws in the classroom they are generally treated as though they are descriptions of nature. They are like the platonic forms that do not exist in the real world. Newton’s laws of motion are close enough to reality that they have practical applications.

I am sure that Newton with his sophisticated mind knew that, but students are introduced to the laws of motion as though they are perfect descriptions of the real world. They aren’t.

However, when the speed of the bodies approaches the speed of light Newtonian laws of motion become inadequate as no longer even good approximations.

Duality is the quality of being made up of two elements or aspects. In order to perceive the two elements or aspects we have to perceive them. The perception of the two aspects requires human or other intelligent mental activity to divine those aspects.

Yin and Yang are abstractions which are applied in Chinese philosophy to various phenomena. However, Yin and Yang are not self-evident in themselves. We may relate the sun to Yin and the moon to Yang or vice versa, but that is a human categorisation.

Can you give an example of duality in nature that is inherent and doesn’t require the human activity of mental abstraction to make it evident?

<<..Source of Life manifests..itself..in the comprehensible and tangible substance..called primordial matter,.giving it an infinite and unimaginable ..variety of attributes..and characteristics.

Thus,..together,..the un-manifested Center of Pure Being..and primordial matter..impregnate all animate..and inanimate manifested creations alike..with their ethereal characteristic.

Primordial matter..fills the whole of creation,and yet,
under the influence..of spirit,..it incessantly transforms itself into new shapes..and forms...

Hence,..through these two completely..opposite..and contrary poles..that govern the whole of creation,..the Law of Duality..comes into play,..controlling..the whole process of life..and creation.

As individuals,..we personally experience..the effects of the Law of Duality..on a daily basis,..since it is part of creation..itself.

However,.in simpler terms,..we could say that duality..is based on the law of attraction..and repulsion,..and therefore creation itself is..founded on the Law of Duality.

But..why is this so?

First,let us clarify..that the invisible complement..of primordial matter..is the unfathomable nature..of unmanifested Being.

Here is the..inconceivable..and extraordinary paradox..that demonstrates..that an unmanifested/essence,..

an essence..that does not belong to..creation..[presence]..itself,..and therefore..does not exist as such..for us,..*[presences]

Dear david f,

>> mathematical models … approximate reality but are an abstraction which does not fully reflect reality. …
Yin and Yang are abstractions which are applied in Chinese philosophy to various phenomena. <<

What an interesting analogy between the role of mathematics in understanding (physical) reality, and that of what I referred to as epistemological tools (Yin-Yang complementarity, beauty-truth-goodness aspects). Or did I misinterpret you?

>> We may relate the sun to Yin and the moon to Yang or vice versa, but that is a human categorisation. <<

Well, we may, but I do not think than any such arbitrary assignment is meaningful, i.e. properly reflects the intrinsic meaning of the Yin-Yang complementarity. Something like, one may assign any mathematical concept to any physical - i.e. a Euclidean space of dimension 13 to physical space, or any other arbitrariness - but it is meaningless unless such a mathematical model is an intrinsic part of a physical theory justified through observation, measurement.

It is not easy to describe explicitly what it means to say that a mathematical model is meaningful, suitable, but it is still easier than to explain what I mean by “properly reflects the intrinsic meaning of the Yin-Yang complementarity”.

Dear David,

.

Thank you for that excellent scientific briefing on Newton’s third law of motion.

I note that like other mathematical models it “approximates” reality but does not “fully reflect” it.

More importantly, the fact that it is recognized as a law, “close enough to reality that it has practical applications”, means that is not just a pipe dream or a mere figment of the imagination. If I understand you correctly, whether mankind perceives it in that manner or not has no influence on the matter whatsoever. That’s just the way it is.

Also, apparently the law has a speed limit close to the speed of light but that shouldn’t be a problem. Who’s worried about elasticity at that speed?

It seems to me that what we are debating here is clearly reality and not just the phantasmagorical elucubrations of some absent-minded professor or even those of a Fields Medal winner, for that matter.

I’m sure we all do our best to keep our minds free of the pride and prejudice that risk to cloud our vision and warp our judgement. I agree that we must be constantly on our guard not to confuse subjectivity with objectivity, but not to the point of denying reality itself existence.

It is my view that if such a broad public from all walks of life, throughout humanity, are capable, not just of perceiving, but of recognizing and attesting, a certain duality in nature, then there is ample circumstantial evidence to support such a case.

And to answer your question: “Can you give an example of duality in nature that is inherent and doesn’t require the human activity of mental abstraction to make it evident? “, I reply male and female, life and death. Neither are abstract, both are real Both are independent of mankind.

But I am more than willing to admit that time may prove me wrong.
