Perhaps one of our list members attended the meeting of the History of Science Society a few months ago, which if I remember correctly was in San Diego. When I asked an acquaintance about the highlights of the meeting, he described the following paper. A historian had been contemplating clocks in European railway stations, and wondering what mechanical or technical developments were used to coordinate timekeeping as railroads developed. He went on a search of patent records, and found that some of the applications were handled by patent clerk Albert Einstein. Since his first theory of relativity concerns time and simultaneity, this could be an example of a fairly mundane technology motivating some very abstract science.
>But from 1892 the railway companies used Greenwich mean time. >So you were able to get the train of let's say 10:00 by leaving your >home at 10:05 or even later. >Some public clocks had a second (red) minute finger to show the >difference between public time and railway time. _______________________________________ Peter Abrahams [EMAIL PROTECTED] the history of the telescope, the microscope, and the prism binocular
