"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."

"The factor most ignored in discussing interstellar flight is the kinetic energy that must be invested in the ship to make its tons of matter move at a substantial fraction of the speed of light."
"Penn State in 1955 became the first university to be issued a federal license to operate a nuclear reactor, which it continues to use for studies in the peaceful uses of atomic energy and the training of nuclear industry personnel."
"Information comes through to me in 3 basic ways seen, hearing, and feeling the energy of the person that's crossed over. In which it is a symbolic type of language."
"We've got to search back to our last known safe landmark. I can't say exactly where, but I think it's back there at the start of the Industrial Revolution, we began applying energy in vast amounts to tools with which we began tearing the environment apart."
"If anyone has a vested interest in space solar power, it would have to be me."
"If it feels right and I'm not going against any energy in myself or the situation, there would be no limit."
"In modelling, there is no point in trying to prove you have a brain, so why even bother? I'd sooner save the energy for something more meaningful."

"In every area of the world where there is earthquake risk, there are still many buildings of this type; it is very frustrating to try to get rid of them."
"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 repeatedly have to correct this belief. In a sense, magnitude involves steps of 10 because every increase of one magnitude represents a tenfold amplification of the ground motion. But there is no 'scale of 10' in the sense of an upper limit."
"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."
"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."
"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."
"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."
