Being the office supervisor, I had to have a word with a new employee who never arrived at work on time. I explained that her tardiness was unacceptable and that other employees had noticed that she was walking in late every day. After listening to my complaints, she agreed that this was a problem and even offered a solution.
"Is there another door I could use?"
Gerard Henri de VaucouleursBorn 25 Apr 1918; died 7 Oct 1995 at age 77.French-born U.S. astronomer whose pioneering studies of distant galaxies contributed to knowledge of the age and large-scale structure of the universe. He produced three Reference Catalogues of bright galaxies (1964, 1976, 1991). Each was a homogenization of data from widely different sources, so that the catalogues would not be merely finding lists or data collection lists, but astrophysically useful databases. Using data in the Reference Catalogues, he was able to develop new distance indicators and refine others. His unique philosophy on distance matters was "spreading the risks," that is, applying as many different and independent techniques as possible to check for scale and zero-point errors. |
