Like if you cant describe it in language thats readily apparent to everyone I dont think you understand it. thats my idea anyways. Even einstein's theory of relativity is readily comprehensible. Speed has a direct correlation to the experience of time. That opens up a whole plethora of phenomena that we werent aware of beforehand, and its easily explainable. This on the otherhand, not so much.

"You can probably see where we're heading. If you want to see something in the distance, you can use two convex lenses, placed one in front of the other. The first lens catches light rays from the distant object and makes a focused image a short distance behind the lens. This lens is called the objective, because it's nearest to the object you're looking at. The second lens picks up that image and magnifies it, just like a magnifying glass magnifies an image on paper. If you put the two lenses in a closed tube, hey presto, you have a telescope."

From here: http://www.explainthatstuff.com/binoculars.html

I learned something today: binoculars are basically two compact telescopes and there are two mirrors on each side that focus via the focus wheel mechanism, thats why it looks like it "zooms" when u focus the light. Convergence then divergence with zooming (aka moving the mirrors back and forth).

:lol: Thats literally all there is to it. Its angles and geometry.

Silence with your simplistic explanations, Im trying to maintain an air of impenetrable ambiguity.

Lets just say binoculars are based on quantum physic principles. Sounds better that way :shrug:

It makes me feel smarter, which is the ultimate goal either way. Bow to me :crankey:

I bow to no one!

Except Jesus and God, if they showed theirselves before my eyes (with bionculars).

Binoculars and cameras depend on the wavelike properties of light to focus an image onto a surface - binoculars on the retina and cameras on the film or sensor. Digital camera sensors actually take advantage of light's quantum properties by counting individual photons.

Lenses do two things. They collect light and they focus it, and there is a trade off between the two. A very large lens can collect a lot of light, but only focus on things at a specific distance. A small lens doesn't collect as much light but has much more in focus.

A pinhole lens will have everything in focus. Someone who normally requires glasses to focus things at a distance can look trough a hole In paper or through their fingers and focus on distant objects without glasses

I study physics. The branch of optics you guys are interested in is called geometric optics. If you're genuinely interested in learning about geometric optics, here's a good basic introduction. It uses a bit of mathematics like trigonometry and simple algebra, so it's highschool-level or possibly first-year undergrad if somebody had no background. The relevant part is III, "Image formation with lenses", but you'll have to read everything up until that point to really understand it.
