Documentary | Discovery Channel – Understanding : Electricity | 900MB

Almost all our world depends on electricity, on electrons in motion. They flow through countless switches and machines not unlike water through aqueducts and canals. They flow through our bodies and brains as if they were the spirit of our blood and bones. They can even start life as they did when researchers cloned a sheep named Dolly. A tiny spark of electricity was used to fuse cells and start the egg growing into an embryo. All this started with a curious fellow back in 1752. That was when a man with a key, Benjamin Franklin, stepped out into a storm with a kite. He snatched lightning from the heavens and introduced electricity to mankind. With this gift, mankind has shaped reality with the colors, shapes and sounds of imagination itself.
