A new vocabulary item has been added to English dictionaries: Covid-19. For linguists, the addition of a meaningful linguistic element to any language should change the whole language as, for T. S. Eliot, a new poem changes the whole literature of a nation. But let us see how seriously the addition of the vocabulary item Covid-19 might change the English language. According to Cambridge online ...
متن کاملv 1 2 8 N ov 1 99 8 Spacetime Exterior to a Star
In many circumstances the perfect fluid conservation equations can be directly integrated to give a Geometric-Thermodynamic equation: typically that the lapse N is the reciprocal of the enthalphy h, (N = 1/h). This result is aesthetically appealing as it depends only on the fluid conservation equations and does not depend on specific field equations such as Einstein’s. Here the form of the Geom...

Theoretical considerations and observational data support the idea that mergers were more frequent in the past. At redshifts z = 2 to 5, violent interactions and mergers may be implicated by observations of Lyman-break galaxies, sub-mm starbursts, and active galactic nuclei. Most stars in cluster ellipticals probably formed at such redshifts, as did most of the halo and globular clusters of the...
متن کامل6 v 1 1 0 N ov 1 99 8 Measurement of the D s Lifetime
We report the results of a precise measurement of the Ds meson lifetime based on 1662± 56 fully reconstructed Ds → φπ decays, from the charm hadroproduction experiment E791 at Fermilab. Using an unbinned maximum likelihood fit, we measure the Ds lifetime to be 0.518 ± 0.014 ± 0.007 ps. The ratio of the measured Ds lifetime to the world average D0 lifetime [1] is 1.25 ± 0.04. This result differs...

This is a brief presentation of historical introduction to the theoretical concept of neutrino oscillation during the early stage of the studies up to 60's. 1 Prediction of µ and ν µ (1942) and Critiques by Sakata Let me begin with Sakata, that would concern with the theme of this talk. In 1942, Sakata and Inoue proposed the so-called " two-meson theory " [1]. Their theory was to claim the exis...
