    I am currently analyzing the emission line spectra of the approximately 600 galaxies from the sample of Cohen et al. (2000) and Cohen (2001) in the region of the HDF-North with z<1.5. A progress report on this effort of the Caltech Faint Galaxy Redshift Survey is presented.Comment: For the proceedings of the meeting held in Cozumel, March 2002 on Galaxy Evolution: Theory and Observations, to be edited by V.

    Universal Constants, Standard Models and Fundamental Metrology

    Taking into account four universal constants, namely the Planck's constant hh, the velocity of light cc, the constant of gravitation GG and the Boltzmann's constant kk leads to structuring theoretical physics in terms of three theories each taking into account a pair of constants: the quantum theory of fields (hh and cc), the general theory of relativity (cc and GG) and quantum statistics (hh and kk). These three theories are not yet unified but, together, they underlie the standard models that allow a satisfactory phenomenological description of all experimental or observational data, in particle physics and in cosmology and they provide, through the modern interpretation of quantum physics, fundamental metrology with a reliable theoretical basis

    Note on Two Theorems in Nonequilibrium Statistical Mechanics

    Full text link
    An attempt is made to clarify the difference between a theorem derived by Evans and Searles in 1994 on the statistics of trajectories in phase space and a theorem proved by the authors in 1995 on the statistics of fluctuations on phase space trajectory segments in a nonequilibrium stationary state.Comment: 3 pages, Revte
