Hydrogen Dioxide
This is not hydrogen peroxide (H2O2). This is one atom of hydrogen bonded to two atoms of oxygen: and, yes, that’s impossible by the laws of chemistry! Well-spotted. Or perhaps not well-spotted, as chemists who contemplate hydrogen dioxide for too long can end up needing a nice rest cure for a while. Or else, possibly trepanning: our ‘colleagues’ behind the Iron Curtain have some alarming techniques for combating acute cases of paradigm discontinuity syndrome.
