"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."
"We are probably nearing the limit of all we can know about astronomy."
"From the first moment I handled my lens with a tender ardour."
"This sight... is by far the noblest astronomy affords."
"Anything that had happened once on Earth should be expected millions of times elsewhere in the Universe, that was almost an article of faith among scientists."
"Stars are fires that burn for thousands of years. Some of them burn slow and long, like red dwarfs. Others-blue giants-burn their fuel so fast they shine across great distances, and are easy to see. As they start to run out of fuel, they burn helium, grow even hotter, and explode in a supernova. Supernovas, they're brighter than the brightest galaxies. They die, but everyone watches them go."
"But when researchers at Bell Labs discovered that static tends to come from particular places in the sky, the whole field of radio astronomy opened up."
"Did you say the stars were worlds, Tess?""Yes.""All like ours?""I don't know, but I think so. They sometimes seem to be like the apples on our stubbard-tree. Most of them splendid and sound - a few blighted.""Which do we live on - a splendid one or a blighted one?""A blighted one."

"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."
