Spacetime By Miroslav Holub
			When I grow up and you get small, then -- (In Kaluza's theory the fifth dimension is represented as a circle associated with every point in spacetime) -- then when I die, I'll never be alive again? Never. Never never? Never never. Yes, but never never never? No . . . not never never never, just never never. So we made a small family contribution to the quantum problem of eleven-dimensional supergravity.   (translated by David Young and Dana Hábová)
