And they were in overlapping fields - for example, the magnitude scale.
For my own personal growth I had to set out on my own.
Gutenberg and Richter were very great men.
I had an agenda. It was a very smooth transition.
In many places where you have these kinds of people - very strong, very confident people - the atmosphere is frenetic and tense and unpleasant.
It was a marriage of convenience. Everybody recognized it as that, but we didn't think it was an extraordinary thing. The lab was a very nice place.
It's a difficult question of relations between people.
Maurice Ewing, whom I had studied with and on whose staff I worked at the Lamont Geological Observatory, was a giant, and I wanted to diversify into other fields.
My attitude toward graduate students was different, I must say. I used graduate students as colleagues: I gave them the best problems to work on, and I encouraged them.
Postdocs are needed to build a modern research team; you want to bring in people with different backgrounds and different skills.
The notion of graduate students as colleagues rather than students is a more modern notion, I think - across the country, in many different fields.
The quickest way to find out is to go down the list of my publications, because they were all co-authors of papers with me.
Well, when the world's greatest laboratory makes you an offer, you take it seriously.
When the first computers started to come in, we tried to digitalize the seismological equipment.
You travel across the country, you visit departments, you give talks, you talk about the work at your laboratory - what's going on, what the opportunities are there - you talk about your own research.
Your perception is correct. The original concept of the logarithmic scale was Richter's, but the important thing is worldwide magnitudes and that's what Gutenberg contributed, mostly - although Richter helped out as well.
