This day in Electrical History

On October 21, 1879 Thomas Edison created a light bulb that lasted 13.5 hours.

Without this invention, we'd still be lighting candles and lamps every night (and putting up with all that smoke). The only downside is now it's harder to see the stars in the sky from all the light cities put out!

Here's a picture of the earth at night taken by NASA. Check out those big cities! Shame about the places with no lights yet.
