QUATERNION, POLAR / DEPOLAR
Text: Hamilton: "There seems to me to be something analogous to polarized intensity in the pure imaginary part; and to unpolarized energy (indifferent in direction) in the real part of a quaternion: and thus we have some slight glimpse of a future Calculus of Polarities."
