You Think You Know Light? 5/2/2005 12:17:49 PM
Do you like Rainbows
Research from when I did an article on light source for a biblical seminar. I couldn't possibly put it all up, you'd shoot me. ( you might even now;-).Read science explanation below, it's updated and very interesting.

Religion
"Claiming that no theologically trained priest or outward rite is needed to establish communion between the soul and its God, Fox taught that everyone could receive whatever understanding and guidance in divine truth they might need from the “inward light,” or “inner light,” supplied in their own heart by the Holy Spirit."
Genesis 1:3-5 "Then God said, Let there be light, and there was light. 4..God saw the light that it was good and divided the light from the darkness.5..God called the light day, and the evening he called night. So the evening and the morning were the first day."
Psalm 89:37-38 "His posterity shall continue forever and His
throne shall be like the Sun before me; like the moon which remains forever a faithful witness in the sky." (David)
John 8:12"Then Jesus spoke to them again saying,' I am the light of the world,he who follows me shall not walk in darkness,
but have the light of life."
A short poem I wrote for article
The light of the world
Is the light that gives life
In more ways than one
We get it from sun/Son
Science and religion can be one
Since all things come from the Son
Creator shares more than His love
He shares His light from up above
From the life giving Sun
From the moon in the night
From the stars more than one
All are sources of light
What we see in the dark
What we see in the day
All from the same spark
Of God's energy display
Science
"You'd think we'd have figured out light by now. Yet knotted up within the theory is a phenomenon that physicists are still unraveling: an unexplored property of light.
In addition to color (which depends on the wavelength of the electromagnetic wave) and polarization (the orientation of the wave), light beams can also possess orbital angular momentum (the shape of the wave fronts). Optics researchers discovered this property a decade ago, but for some reason this realization has failed to propagate much beyond a small community of specialists [see "Hands of Light," Innovations, Scientific American, August]. It has barely been noticed even by those with the greatest need to exploit every conceivable aspect of light--namely, astronomers.
An astronomer has now taken it upon himself to spread the word. In the November 10-03, Astrophysical Journal, Cornell University emeritus professor Martin Harwit suggests that the orbital angular momentum of light could convey new information about celestial bodies--information unavailable by looking just at color and polarization. "The paper was mainly meant to be provocative," he says. "People are flabbergasted that this should even be possible."
Like polarized light, twisted light carries angular momentum: in lab experiments, it has set small plastic beads spinning. If you think of light in terms of particles (photons) rather than waves and neglect some quantum-mechanical caveats, it is as though the photons were zipping along a corkscrew path.
To create twisted light, physicists shine a laser through a helical lens or a special diffraction grating. Harwit argues that light could also be twisted by natural processes in the universe, such as lenslike density variations in interstellar gas or the warped spacetime around rotating black holes. Alien civilizations might transmit information by twisting light rather than using other encoding methods (as indeed physicists have proposed for terrestrial free-space communications"
note(Some say this "corkscrew or twisted light" method could explain the rainbow);-)
