None of this is in dispute. Please don't conflate optics or how light works with what he is demonstrating regarding the eyes.Peacegirl
I am not attacking you personally, I am po8ning out the issues with what you are saying on optics. It is what go0ess on with the forum, debate and critique over what is said. No need to take personally.
An impulse has a specific definition, impulses are not created in the brain, it is ore of a continuous process. Your use of the word impulse sounds like pre 20th century philosophy and metaphysics.
Take a simple circular thin lens and point it at an object that is lit up. Put a piece of paper at the focal plane and you will see an image of the object on the paper, inverted. That is essentially a camera.
In optics there are two general categories, geometric optics and physical optics.
In geocentric optics rays are traced from points on an object through the lens and the focal plane. The process is computerized.
In physical optics Maxwell's equations are solved.
In geometric optics image formation is easy for a thin lens. Rays are traced from points on the object to the lens which are bent,refracted, and pass through the focal plane.
The image exists at all points between the object and the lens. The image exists as interference patterns of light waves.

The meaning of intensity can be a little murky.

The Huygens–Fresnel principle (named after Dutch physicist Christiaan Huygens and French physicist Augustin-Jean Fresnel) states that every point on a wavefront is itself the source of spherical wavelets, and the secondary wavelets emanating from different points mutually interfere.[1] The sum of these spherical wavelets forms a new wavefront. As such, the Huygens-Fresnel principle is a method of analysis applied to problems of luminous wave propagation both in the far-field limit and in near-field diffraction as well as reflectionHuygens–Fresnel principle - Wikipedia

There are older basic optics texts in pdf, I will find one for you if you want.
Optics For Dummies. Dummies is a misnomer, the 'for dummies' books are well written for the non technical reader.

The easy way to shed light on Optics In general terms, optics is the science of light. More specifically, optics is a branch of physics that describes the behavior and properties of light'including visible, infrared, and ultraviolet'and the interaction of light with matter....www.barnesandnoble.com
This has been going on for years. It's like being married to an abuser. Thank the Lord I'm not married to one of them.There is a point at which critique becomes abusive.
Steve, all of this was explained to her, repeatedly, at FF, including by one biologist and two astrophysicists. It was explained repeatedly across more than 2,000 pages. You might want to save yourself the trouble. And yes, according to her, everyone who disagrees with her is attacking her personally, and “ruining it” for everyone else. We pointed out to her, for example, that if we see in real time because of “how the eyes and the brain work,” whatever that is supposed to mean, then what about cameras? A camera doesn’t have a brain. So if God turned on the sun at noon and we saw it immediately, without having to wait 8 minutes for the light to arrive, and then took a picture of the sun, would the camera take a photo of the sun in real time, or would it have to wait eight minutes for the light to arrive? You should have seen what knots that put her into! First she adopted one position — that the camera would have to wait for the light to arrive. But then, when we pointed out to her that if this was true, what we see, and what cameras take pictures of, would never be the same, but in fact they are — she took exactly the opposite position! That cameras take pictures without having to wait for light to arrive at the lens.
You cannot educate someone like this, someone who, moreover, contends that those who disagree with her secretly know that she and the author are correct, but are “furious” at having their “world view” challenged.
I appreciate it. Pood wants everyone to dismiss me as if I have nothing of any value to offer.I have no clue as to why you draw me into your battle, I have no axe to grind with peacegirl.
He wasn't quirky Steve. He was an independent thinker. Quirky sounds weird or someone not to be taken seriously.She has no science background, so what. She follows some quirky offbeat author, so what.
I am glad you can identify because, at the very least, you understand where I'm coming from. Sometimes being treated unfairly and knowing what it feels like to be misunderstood gives a person a special kind of compassion where none would exist, so thank you.I have had my moments for sure over the years.
