Before I saw this question, I had never even wondered why glass was transparent. It just was.
But as soon as I saw the question, I was amazed that I had never asked it. I knew I had to know the answer.
And now I do!
Bam! Thank you Science!
For one of my Christmas present's this year I asked for Carl Sagan's Cosmos on Dvd. I'm very slowly working my way through it. It is a series that needs to be appreciated slowly, as one appreciates a fine wine.
Carl Sagan was a poet, as well as a scientist, and every word he say during Cosmos deserves to be savoured, and fully appreciated, before moving onto the next one.
This is an old video I know, but it never ceases to amaze me. Carl Sagan sums up in this 8 minutes my connection to all of life, to the earth itself, and to the universe, so beautifully, that I can't hope to mimic it. And, so, instead. I will let him do it for me.
This is the famous Star Stuff Video. Take a moment to encounter it once again. Let Sagan remind, how you were formed by the stars.
