"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."

"One of the extraordinary things about human events is that the unthinkable becomes thinkable."
"Which suggests something about media and war: it's not just that events happen and the media documents and presents them. There is a third element: what the public is ready to accept, what the public wants to know."
"There are events which are so great that if a writer has participated in them his obligation is to write truly rather than assume the presumption of altering them with invention."
"In the following pages I have endeavoured to describe all that appeared to me most important and interesting among the events and the scenes that came under my notice during my sojourn in the interior of Africa."
"The constant flux and caprice of mental events do not admit of the establishment of stable experimental conditions."

"This is very similar to astronomy where different magnitudes are assigned to the brightness of an astronomical object, depending on the range of wavelengths being measured."
"My amateur interest in astronomy brought out the term 'magnitude,' which is used for the brightness of a star."
"What emerged, of course, was that the magnitude scale presupposed that all earthquakes were alike except for a constant scaling factor. And this proved to be closer to the truth than we expected."
"I suggested that we might compare earthquakes in terms of the measured amplitudes recorded at these stations, with an appropriate correction for distance."
"There is another common misapprehension that the magnitude scale is itself some kind of instrument or apparatus. Visitors will frequently ask to 'see the scale.'"
"Emphasis was usually put on the horizontal acceleration factor, for the simple reason that ordinary structures have a built-in safety factor for the vertical component; that is, gravity."
"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."
"If the assumptions used in calculating energy are changed, then this seriously affects the final result, even though the same body of data might be used."
"Refining is inevitable in science when you have made measurements of a phenomenon for a long period of time."
