Irish Thought for March 11....

Irish Trivia

Why is the sky blue?  Joy Tyndall, an Irish scientist, was the first to correctly explain.  In 1859, he discovered that the sun emits a full spectrum of light, but our eyes see the colors blue and red more acutely.  The sun's blue light is scattered by molecules in the air faster than they scatter red light.  The sky during the day looks blue because less blue light has been scattered.  By the time the sun sets, most of the blue light has been refracted away, so the color of the sky tinges with red.

Don't forget today is the start of daylight saving's time.  I hate losing an hour.  It makes me feel off for about a week.
