The scope of the sequence contains: foundations of computing device technology; software program conception and perform; schooling; machine purposes in expertise; conversation structures; platforms modeling and optimization; details platforms; desktops and society; computers expertise; defense and security in details processing platforms; synthetic intelligence; and human-computer interplay.
Nuclear physics is shortly experiencing a thrust in the direction of primary phy sics questions. Low-energy experiments assist in trying out past latest stan dard types of particle physics. the hunt for finite neutrino lots and neutrino oscillations, for proton decay, infrequent and forbidden muon and pion de cays, for an electrical dipole second of the neutron denote many of the efforts to check modern theories of grand unification (GUTs, SUSYs, Superstrings, .

McClure, that one of the four stars is itself a spectroscopic binary. This is an object lesson to me. The amplitude of the variation is about equal to the measuring error and although I have made more than a thousand observations of the star I have usually compared it with stars which are themselves variable so the variation of the reference star has not been apparent. BATTEN of the stars with which I have compared it. BATTEN: It is an object lesson to us all: even 1000 observations may not be enough.
5 Amm- l , is related to this systematic error is not yet clear. The existence of a minimum random error, however, is of increasing importance as our potential internal precision improves. The minimum value was not large enough to be important for the old singleprism spectrographs - even in measures of solar-type stars. It is now comparable in size with the external scatter we find in our THE CHOICE OF STANDARD STARS 13 "conventional" high-dispersion observations. 01 km s-l is claimed (Campbell 1983, Serkowski 1976).
I hope that at this meeting we arrive at a better set of standards; the "Centre de Donn~es Stellaires" has deliberately tried to get available lists published. They are scattered allover the literature and they should be published, assembled and critically discussed at the same place so that astronomers may use them more easily. GARRISON: It is not the simple average, but as I mentioned, it does 28 R. F. GARRISON include the definition as well as the evolution of the system. g. e. for which very few measurements exist), hoping that the "bad" ones can be recognized and eliminated afterwards during the reduction.
