  • Democritus ? Scientific Wizard of the 5th Century BC (1998) [Updated 1 decade ago]
    by Robert L. Oldershaw   read the paper:

    Roughly 2400 years ago, during an era largely characterized by unscientific thought, a school of natural philosophers led by Democritus of Abdera developed a remarkably accurate understanding of our physical world. How could this small group have discovered so much at a time when technology and mathematics were at such a rudimentary level? What if their methods and ideas had caught on immediately, instead of being virtually ignored for 2000 years?

  • Keeping Theoretical Physics on Track (1994) [Updated 1 decade ago]
    by Robert L. Oldershaw   read the paper:

    During the early 1980s theoretical physicists were so impressed with the perceived potential of Grand Unified Theories in particle physics, and the Inflationary Scenario in cosmology, that some were envisioning an 'end of physics' and were wondering what to do after the basic foundations of theoretical physics were 'finished'. Rest assured, their jobs were never in jeopardy, and many theoretical physicists have backed away from such grandiose claims. However, from the way that phrases like 'theory of everything' and 'wavefunction of the Universe' are still popping up, it appears that the disease 'unreasonable confidence in highly speculative models' has not been eradicated, but rather is only in partial remission.

  • Discrete Scale Relativity and SX Phoenicis Variable Stars
    by Robert L. Oldershaw   read the paper:

    Discrete Scale Relativity proposes a new symmetry principle called discrete cosmological self-similarity which relates each class of systems and phenomena on a given Scale of nature's discrete cosmological hierarchy to the equivalent class of analogue systems and phenomena on any other Scale. The new symmetry principle can be understood in terms of discrete scale invariance involving the spatial, temporal and dynamic parameters of all systems and phenomena. This new paradigm predicts a rigorous discrete self-similarity between Stellar Scale variable stars and Atomic Scale excited atoms undergoing energy-level transitions and subthreshold oscillations. Previously, methods for demonstrating and testing the proposed symmetry principle have been applied to RR Lyrae, ? Scuti and ZZ Ceti variable stars. In the present paper we apply the same analytical methods and diagnostic tests to a new class of variable stars: SX Phoenicis variables. Double-mode pulsators are shown to provide an especially useful means of testing the uniqueness and rigor of the conceptual principles and discrete self-similar scaling of Discrete Scale Relativity.
