Light is energy propagated at a visible wavelength. Its definition is inseparable from its velocity. That is, nothing can equal the speed of light without being light --so it also serves as a universal constant, particularly in this equation: E= mc2. When we are young algebra students, it is almost irresistible, we divide both sides of the equation by c2 and discover ourselves to be E, kinetic energy, and m, relativistic mass. In short, we are the square root of light.
Creation myths generally describe building archetypal humans out of water and earth --after adjustments are made by the creator to the velocity of light resulting in seas and minerals. Scientific evidence suggests we crawled from the water in search of new evolutionary opportunities. Whether scientific, scriptural or metaphorical, creation stories abound. I rather like to include a bit of supernature, which is why this is my favorite creation myth:
"Frosty the Snowman, was a jolly happy soul,
With a corn cob pipe and a button nose, and two eyes made of coal.
Frosty the Snowman, is a fairytale, they say.
He was made of snow, but the children know he came to life one day.
There must have been some magic in that old silk hat they found,
For when they placed it on his head, he began to dance around!"
My appreciation to Doppler, Einstein and the songwriting team of Nelson and Rollins. And to all from this hot California summer: Remember the winter sometimes and try to dance around a little. I do!
