Albert Einstein said, 'If at first an idea does not sound absurd, there is no hope for it.' Physics of the Impossible shows how our most far-fetched ideas today - from Star Trek's phasers and teleportation to time travel as envisioned by Back to the Future - are destined to become tomorrow's reality. Michio Kaku, bestselling science author and one of the world's most acclaimed physicists, looks at the technologies of the future and explains what's just around the corner, what we might have to wait a few millennia to get our hands on and how surprisingly little of it is truly impossible.
