“Scientists have created a new kind of matter: It comes in waves and bridges the gap between the everyday world of humans and the micro-domain of quantum physics… Bose-Einstein condensates (“BECs” for short) aren’t like the solids, liquids and gases that we learned about in school. They are not vaporous, not hard, not fluid. Indeed, there are no ordinary words to describe them because they come from another world — the world of quantum mechanics.” Science@NASA
