    Automated search for supernova explosions (1988)
    [S.l.] : American Institute of Physics (AIP)
    Review of Scientific Instruments 59 (1988), S. 1021-1030

    Notes: We describe the design and construction of a new search for supernovae, based on the use of current computer and detector technology. This search uses a computer-controlled telescope and charge coupled device (CCD) detector to collect images of hundreds of galaxies per night of observation, and a dedicated minicomputer to process these images in real time. The search system has a detection threshold of 17th visual magnitude, discovered its first supernova on 18 May 1986, and at this writing has found three additional supernovae. The system currently is being upgraded with an improved detector and a more powerful computer. At full speed and sensitivity, the system will be able to search 2500 galaxies per night with a limiting magnitude of 19 or fainter.

    Notes: [Auszug] In view of the recent prolonged controversy5, a more fruitful approach might be to find the specific source of "regrettable error" on Prof. Dingle's part. I have done this, by examination of Prof. Dingle's recent Physical Society paper6. There (p. 930), Prof. Dingle makes a key statement which is ...

    Experimental Verification of the ‘Clock-Paradox’ of Relativity (1957)

    Notes: [Auszug] In order to guarantee the above prediction, three assumptions are sufficient : (1) The time dilation of special relativity holds for uniform motion. (2) The acceleration of an ideal clock relative to an inertial system has no influence on the rate of the clock, and the increase in the proper time ...
