    Notes: [Auszug] THE application of transfinite numbers to physical theory is admittedly novel, and should be open for critical discussion; none the less, I see no force in the arguments which Mr. Ursell presents. In my communication I implicitly made use of the ccepted relation 2^ °- n^ ° - C, where n is any ...

    Notes: [Auszug] Morpurgo, Radicati and Touschek have discussed2 time reversal, using the following definition. Let r be the position vector, of a particle and r its velocity ; the property of time symmetry, or invariance under time reversal, requires that if equations of motion lead in a time interval t from a ...

    Notes: [Auszug] The "perfect cosmological principle"2 of steady-state theory requires that the space-density of atoms (neglecting local variations) is uniform throughout the space-and (cosmic) time-extent of the universe. Further, each unit of space gives rise to new atoms, by a process of spontaneous creation, at ...

    Gravitation and mass decrease (1982)

    Notes: Abstract Consequences in physical theory of assuming the general relativistic time transformation for the de Broglie frequencies of matter, v = E/h = mc2/h, are investigated in this paper. Experimentally it is known that electromagnetic waves from a source in a gravitational field are decreased in frequency, in accordance with the Einstein general relativity time transformation. An extension to de Broglie frequencies implies mass decrease in a gravitational field. Such a decrease gives an otherwise missing energy conservation for some processes; also, a physical alteration is then associated with change in gravitational potential. Further, the general relativity time transformation that is the source of gravitational action in the weak field (Newtonian) approximation then has a physical correlate in the proposed gravitational mass loss. Rotational motion and the associated equivalent gravitational-field mass loss are considered; an essential formal difference between metric (gravitational) mass loss and special relativity mass increase is discussed. For a spherical, nonrotating mass collapsed to its Schwarzschild radius the postulated mass loss is found to give a 25% decrease in the mass acting as origin of an external gravitational field.

    An interaction interpretation of special relativity theory. Part II (1973)
    Springer
    Foundations of physics 3 (1973), S. 277-295 
    Details
    ISSN: 1572-9516
    Source: Springer Online Journal Archives 1860-2000
    Topics: Physics
    Notes: Abstract The interaction interpretation of special relativity theory (elaborated in Part I) is discussed in relation to quantum theory. The relativistic transformations (Lorentz processes) of physical variables, on the interaction interpretation, are observation-interaction dependent, just as are the physical values (eigenvalues) of systems described by quantum-theoretic state functions; a common, basic structure of the special relativity and quantum theories can therefore be presented. The constancy of the light speed is shown to follow from interaction-transformations of frequency and wavelength variables. A parallelism is suggested between, on the one hand, the Lorentz-Clausius distinction for relativistic transformations, and, on the other, the distinction between observation-dependent and observation-independent natural processes. The empirical study of rates of macroscopic clocks can provide a critical test of the interaction interpretation and of a possible extension to gravitational time changes; the role of time as prior determinant of natural process is at issue. The Hafele-Keating observations are of general relativity effects on clocks in accelerated motion.

    Bovine papillomavirus E5 oncoprotein binds to the 16K component of vacuolar H + -ATPases (1991)

    Notes: [Auszug] Considerations of size, hydrophobicity, cell localization and lack of cysteine residues suggested that the 16K component of the F0-like proton channel of vacuolar H+-ATPases might be the E5-associated 16K protein. To evaluate this possibility, rabbit antiserum generated against the chicken-liver ...

    A Lorentz-invariant clock (1977)
    Springer
    Foundations of physics 7 (1977), S. 245-253 
    Details
    ISSN: 1572-9516
    Source: Springer Online Journal Archives 1860-2000
    Topics: Physics
    Notes: Abstract Relative distance and velocity magnitudes between two arbitrarily moving particles are independent of an observer's reference frame, and may be used to construct theoretically a clock whose rate is Lorentz-invariant. This result is in accord with the principle of relativity, using the interaction interpretation: Relativistic changes arise in association with momentum-energy transfer, rather than in consequence of velocity-induced changes in measuring clocks and rods.
