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.

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.

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.

Incidentally, the usual designation of the magnitude scale to my name does less than justice to the great part that Dr. Gutenberg played in extending the scale to apply to earthquakes in all parts of the world.

Logarithmic plots are a device of the devil.

I suggested that we might compare earthquakes in terms of the measured amplitudes recorded at these stations, with an appropriate correction for distance.

If one introduces the concept of energy of an earthquake then that is a theoretically derived quantity.

I was lucky because logarithmic plots are a device of the devil.

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.

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.

Nothing is less predictable than the development of an active scientific field.

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.

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.

Intensity like signal strength will generally fall off with distance from the source, although it also depends on the local conditions and the pathway from the source to the point.

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.

I'm glad to see the press now referring to the open-ended Richter scale.

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 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.

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.'

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.

Refining is inevitable in science when you have made measurements of a phenomenon for a long period of time.

Remembrance is the only paradise out of which we cannot be driven away.

You learn from a conglomeration of the incredible past - whatever experience gotten in any way whatsoever.

I've danced one time in my life. It was the most mortifying experience I ever had.

The experience of life consists of the experience which the spirit has of itself in matter and as matter, in mind and as mind, in emotion, as emotion, etc.

My best film composing experience was with Elia Kazan.

Education is a private matter between the person and the world of knowledge and experience, and has little to do with school or college.

A novel should be an experience and convey an emotional truth rather than arguments.

By experience we find out a short way by a long wandering.

The experience of democracy is like the experience of life itself-always changing, infinite in its variety, sometimes turbulent and all the more valuable for having been tested by adversity.

Learning teacheth more in one year than experience in twenty.

Well, the hardest thing to do, as we know from our own experience on 9/11 is protect everything all the time.

The most important training, though, is to experience life as a writer, questioning everything, inventing multiple explanations for everything. If you do that, all the other things will come; if you don't, there's no hope for you.

When I reached adulthood, even now, I could afford to belong to a country club. But I could never belong to a private club because of my experience as a child, because it would isolate me from the whole of humanity.

No one I know of has ever had this experience-where you had to sit and wait and wait for a DNA test to come back just so you can write the last page of the book.

If you live long enough, you'll experience everything.

Actually I'd had a certain amount of experience in Europe in the inter-war period, as a banker, and I was also a member of the Board of Directors of the International Chamber of Commerce.

In the case of my book, I don't think it's really the coming-out gay novel that everyone really needed, even though it was received as such. The boy is too creepy, he betrays his teacher, the only adult man with whom he's enjoyed a sexual experience, etc.

Well, I go to the theater today, and its curtain - there is no curtain in this play; the lights go down and go up - and we start. And I live this character for two hours. There are only two of us in the play. And It's a complete experience.

Our job as writers and thinkers in the time is how to bring about the occasions that let people have that first-person experience - or the metaphoric experience that allows them to see human continuity as opposed to total threat, total willingness to do violence.

Experience is never limited, and it is never complete; it is an immense sensibility, a kind of huge spider-web of the finest silken threads suspended in the chamber of consciousness, and catching every air-borne particle in its tissue.

In my fifty years of experience and memory, I have seen the most amazing increase in the standard of living of a people ever achieved anywhere in the world. This is why I am so sure that our system of free competition and industrial development is sound and must be preserved.

The greatest gift is the passion for reading. It is cheap, it consoles, it distracts, it excites, it gives you knowledge of the world and experience of a wide kind. It is a moral illumination.

It's been my experience that every time I think I know where it's at, it's usually somewhere else.

The experience of learning how to get straight to the core of a problem proved to be of immense value later when I had a long succession of responsibilities in large, complex government departments.
