Robert Bridson has published much research in this area. http://www.cs.ubc.ca/~rbridson/

The real paradox is that it's actually great fun to go back and get to know the maths intimately at the most basic level , for only then you begin to appreciate that there is no way to even start to understand QM without the solid foundations! This is much more powerful than any so-called...

Don't you find that people whom are taken by the woo have only maybe pre-algebra level mathematics anyways? It's quite simply impossible for them to form logical and deductive reasoning at any level.

Nope - think of Physics Forums as a site to disabuse you of the notion that philosophy is a substitute for mathematical rigour :)

Just look at the links below this thread under 'Similar discussion for...: i.e. https://www.physicsforums.com/threads/what-happened-to-the-philosophy-section.657424/

To clarify, it's part of the ice cloud halos, on the same side of the sun, opposite side to a rainbow. https://en.wikipedia.org/wiki/Halo_(optical_phenomenon)

This seems similar to Edwin Land's Retinex theory: "The Retinex Theory of Color Vision Λ retina-and-cortex system (retinex) may treat a color as a code for a three-part report from the retina, independent of the flux of radiant energy but correlated with the reflectance of objects " The...

Since finding PF, I never visit SE or others. After 10+ years on any forum you should have seen it all. Not sure why anyone would think it should be as interesting after all that time.

You want to read up on the Gossamer Condor. Flight of the Gossamer Condor

What will help date the current effects shots is a lot to do with the available software and computing power. Some of the latest rendering research is looking at using neutron transport, which should help with realism: http://www.fxguide.com/featured/its-not-rocket-science-oh-wait/ "But d'Eon...

6 feet would take light approx. 6 nanoseconds to travel. What's your thinking on why it would take 1/4 l.y.?

Yep - looks to be a double rainbow, with a reflected one, taken near sunrise/set. IIRC I photographed a simpler one a decade ago; single and a reflected single that came off the ocean. Edit: Found the slide film, popped on the monitor and photographed; it was a double and a fainter reflected...
