摘要

I arrived at the Caltech Seismo Lab early in May 1972.The faculty and graduate students had the run of an old mansion(Donnelly Lab)that was slightly tattered around the edges but conducive to both all-night work sessions and goofing off since it still had well-kept grounds that included a tennis court.Most of the graduate students occupied the large dining room on the first floor and we hunted out our advisors,when needed,by trying their offices around the rest of the house,checking out the tennis courts,or visiting the coffee pot in the basement.
