"My amateur interest in astronomy brought out the term 'magnitude,' which is used for the brightness of a star."

"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."
"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."
"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."

"As seismologists gained more experience from earthquake records, it became obvious that the problem could not be reduced to a single peak acceleration. In fact, a full frequency of vibrations occurs."
"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.'"
"Refining is inevitable in science when you have made measurements of a phenomenon for a long period of time."
"From here, it becomes an engineering problem; the engineer considers the ground motion that will occur and evaluates the requirements of the proposed structure in the light of the local foundation conditions."
"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."
"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."
"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."
"I usually point out that most loss of life and property has been due to the collapse of antiquated and unsafe structures, mostly of brick and other masonry."
"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."
