? The difference between a brain and a computer can be expressed in a single word: complexity. The large mammalian brain is the most complicated thing, for its size, known to us. The human brain weighs three pounds, but in that three pounds are ten billion neurons and a hundred billion smaller cells. These many billions of cells are interconnected in a vastly complicated network that we can't begin to unravel as yet. (popular science )
? When a graphite crystal is crushed, it breaks into micro-scaled laminar flakes. They are many dangling bonds on the edge of an isolated graphite micro-sheet which elevates its energy and makes it unstable. When a graphite micro-sheet curls into a nanotube, the number of dangling bonds decreases, and the system energy is reduced accordingly.
