Jakob Bernouli, a mathematician from a great family of brilliant people, called the logarithmic spiral spira mirabilis, or "the Miraculous Spiral," so called because the size increases but its shape is unaltered with each successive curve.

The Richter Scale is logarithmic, that is an increase of 1 magnitude unit represents a factor of ten times in amplitude.

Rasool and Schneider argued that an 8fold increase in CO2 would only increase global temperature by 2°C, because the temperature response to increasing CO2 is logarithmic, that is, each successive increment of CO2 has less effect than the one that preceded it, so the temperature response curve becomes progressively flatter.

The magnitude scale for earthquakes is logarithmic, meaning a magnitude 3 earthquake would produce waves with amplitudes 10 times greater than a magnitude 2 and 100 times greater than a magnitude 1.
