The mysterious nature of time

[Confused]

What is polarized light? -- Polarization is the aligning of vibrations in a transverse wave, usually by filtering out waves of other directions. Polarized light waves only travel vertically or horizontally -- when combined at right angles they block each other out and no net light can be detected.

I know it isn't the same thing, but this reminded me of a demonstration I saw at a seminar produced by Kodak back in my film camera days. The instructor was illustrating the additive properties of light. With pigments, white is the absence of color.

Subtractive color: http://en.wikipedia.org/wiki/Subtractive_color


But with light, white is the PRESENCE of color.

Additive color. http://en.wikipedia.org/wiki/Additive_color

Interesting to study the way light works to allow us to see colors.

The subtractive and additive tendencies are very interesting, Ruth. I think they could have parallels with spiritual polarization. It would be useful to study nature to understand the mechanics of polarization, I think.

It's interesting how we can only see a small portion of the electromagnetic spectrum. I think it's like one inch compared to a football field or more.

I have never been able to understand what electromagnetism actually is. How many ever definitions I read, the tangible sense always eludes me.

A fleeting pulse of light has been captured and then made to reappear in a different location by US physicists.
