The air temperature is between twenty and thirty degrees. The ground is covered by about seven inches of snow. I have spent the last two-and-one-half hours enjoying it.
As usual, my mind wandered to the microscopic level as I walked a trail through the woods with my lady. I thought, snow is water. The only difference is that snow molecules move more slowly than water molecules. The molecules are the same in terms of atomic configuration. Only the speed of their vibration is different.
Yet, light passes right through water. It does not pass through unscathed, though. It is refracted, showing us the secret of the color spectrum hidden within pure, invisible (but not indivisible) light.
Snow, on the other hand, does not allow light to pass through it. Nevertheless, it still shows us another secret of light; the whiteness of every color combined. For mysterious reasons, the low frequency of vibration in snow molecules blocks all light, showing us the purity of light unrefracted, in it's whole form.
In the microscopic realm, as frequencies increase, the structure of an object as a whole begins to lose its form. At the higher frequencies, solid objects cease to be themselves altogether, becoming liquid, then gas, then something even more mysterious yet.
But, when light interacts with snow, that effect appears to be reversed. The lower frequencies show us a whole that is typically hidden from our eyes!
This day inspires me to praise these mysteries.
