spring men young
Spring makes everything young again except man.
confusion confusing use
Lately there have been complaints that the use of the magnitude scale is confusing, or at least the reporting of magnitudes in the newspapers 'confuses the public.
distance fall may
Magnitude may be compared to the power output in kilowatts of a [radio] broadcasting station; local intensity, on the Mercalli or similar scale, is then comparable to the signal strength noted on a receiver at a given locality. Intensity, like signal strength, will generally fall off with distance from the source; it will also depend on local conditions at the point of observation, and to some extent on the conditions along the path from source to that point.
earthquakes risk trying
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.
running earthquakes walks
I would walk - not run - to the nearest seismograph.
earthquakes three judgment
The most remarkable feature about the magnitude scale was that it worked at all and that it could be extended on a worldwide basis. It was originally envisaged as a rather rough-and-ready procedure by which we could grade earthquakes. We would have been happy if we could have assigned just three categories, large, medium, and small; the point is, we wanted to avoid personal judgments. It actually turned out to be quite a finely tuned scale.
knowledge science measurement
The laboratory routine, which involves a great deal of measurement, filing, and tabulation, is either my lifeline or my chief handicap, I hardly know which.
remembrance paradise driven
Remembrance is the only paradise out of which we cannot be driven away.
lying mirrors water
According to Democritus, truth lies at the bottom of a well, the water of which serves as a mirror in which objects may be reflected. I have heard, however, that some philosophers, in seeking for truth, to pay homage to her, have seen their own image and adored it instead.
today way expected
My main point today is that usually one gets what one expects, but very rarely in the way one expected it.
life beautiful country
There is nothing more beautiful than cheerfulness in an old face, and among country people it is always a sign of a well-regulated life.
mother nature children
No joy in nature is so sublimely affecting as the joy of a mother at the good fortune of a child.
earthquakes vibrations facts
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.
earthquakes drs plot
[In plotting earthquake measurements] the range between the largest and smallest magnitudes seemed unmanageably large. Dr. Beno Gutenberg then made the natural suggestion to plot the amplitudes logarithmically.
