Primes

• Logarithmic Perception and Encoding
  • Instrument scales — pH, Richter and moment-magnitude, stellar magnitudes, and decibels are all logarithmic re-encodings of physical quantities.

    This sourceDefines earthquake magnitude as the base-10 logarithm of recorded amplitude, an instrument scale modeled on Pogson's logarithmic stellar-magnitude system; pH (Sørensen) and the decibel are analogous logarithmic re-encodings of physical quantities.
