For example, some stars put out large amounts of energy in the infrared part of the spectrum, so that this can produce a different relative magnitude rating than using light energy from the middle of the spectrum.
By moving them vertically, a representative mean curve could be formed, and individual events were then characterized by individual logarithmic differences from the standard curve.
If one introduces the concept of energy of an earthquake then that is a theoretically derived quantity.
I was lucky because logarithmic plots are a device of the devil.
Logarithmic plots are a device of the devil.
Don't wait for extraordinary circumstance to do good; try to use ordinary situations.
