Observable gravitational and electromagnetic orbits and trajectories in discrete physics
Our discrete and finite version of relativistic quantum mechanics provides an elementary particle physics consistent with the standard model of quarks and leptons. Our recent relativistic calculation of the bound state spectrum of hydrogen has allowed us to make a combinatorial correction to the first order estimate of 1/..cap alpha.. = /Dirac h/c/e/sup 2/ = 137 derived from the combinatorial hierarchy and achieve agreement with experiment up to terms of order ..cap alpha../sup 3/. The same theory requires that to first order /Dirac h/c/Gm/sub p//sup 2/ = 2/sup 127/ + 136 approx. = 1.7 /times/ 10/sup 38/. Using the emission and absorption of spin 1 photons and spin 2 gravitons in this framework, we try to show that we can meet the three additional tests of general relativity---solar red shift, solar bending of light, and precession of the perihelion of Mercury. We predict that a macroscopic electromagnetic orbit would have four times the Sommerfeld precession for basically the same reason that Mercury has six times the Sommerfeld precession. 20 refs
On the Computer Simulation of the EPRâBohm Experiment
We argue that supraluminal correlation without supraluminal signaling is a necessary consequence of any finite and discrete model for physics. Every day, the commercial and military practice of using encrypted communication based on correlated, pseudo-random signals illustrates this possibility. All that is needed are two levels of computational complexity which preclude using a smaller system to detect departures from ''randomness'' in the larger system. Hence the experimental realizations of the EPR-Bohm experiment leave open the question of whether the world of experience is ''random'' or pseudo-random. The latter possibility could be demonstrated experimentally if a complexity parameter related to the arm length and switching time in an Aspect-type realization of the EPR-Bohm experiment is sufficiently small compared to the number of reliable total counts which can be obtained in practice. 6 refs
A paradigm for discrete physics
An example is outlined for constructing a discrete physics using as a starting point the insight from quantum physics that events are discrete, indivisible and non-local. Initial postulates are finiteness, discreteness, finite computability, absolute nonuniqueness (i.e., homogeneity in the absence of specific cause) and additivity
Functional outcome after endoprosthetic limb-salvage therapy of primary bone tumoursâa comparative analysis using the MSTS score, the TESS and the RNL index
Limb-saving therapy for primary bone tumours is the treatment of choice. We aimed at analysing the quality of life of this group of patients by combining three different tools. Eighty-seven patients (46 females, 41 males) with a primary bone tumour of the extremity who had undergone endoprosthetic reconstruction between 1982 and 2000 were included in this retrospective study. The median age at the time of evaluation was 30 (12â73) years. The Toronto Extremity Salvage Score (TESS) and the Reintegration to Normal Living index (RNL) were recorded an average of 5.8Â years after reconstruction and the Musculoskeletal Tumour Society Score (MSTS) after an average of 6.5Â years. The mean MSTS score was 77% (13â93%). The mean TESS was 82% (22â99%), and the mean RNL index was 87% (32â98%). The subjective satisfaction and acceptance of physical impairment were significantly higher than the objective score (pâ<â0.001). The TESS was 88% in patients aged 12â25Â years, 81% in those aged 26â40Â years and 57% in those aged 41â73Â years. Parallel recording of the MSTS score, TESS and RNL index provides a better measure reflecting the complex situation of the patients by combining objective and subjective parameters
