摘要:Einstein stated two dictums, so that more experimental facts can replace the previously adopted hypotheses and General Relativity (GR) can evolve to “grand aim” or perfection. In the absence of appropriate experimental facts during pre-CEREPAC ( C entury-long E xperience of ...

摘要:Jiménez and Maroto [Phys. Rev. D 83 , 023514 (2011)] predicted free-space, longitudinal electrodynamic waves in curved space-time, if the Lorenz condition is relaxed. A general-relativistic extension of Woodside’s electrodynamics [Am. J. Phys. 77 , 438 (2009)] includes a dyn...

摘要:Certain relationships between the Newtonian gravitational constant, the Planck constant, and the square of the fine structure constant, established by dimensional analysis, are presented. Here we show that, based on these relationships, a more exact value for the Newtonian g...

摘要:Quantum theory is extremely successful in describing the micro cosmos. The caveat is that nobody knows what quantum objects really are. Consequently, the intention of this article is not to introduce any new formalism but to develop some ideas about the ontological meaning o...

摘要:Gravity has been shown in theories of relativity to be the curving of space around massive bodies. Thus, objects in orbits are following a straight line along a curved space. Why massive bodies curve space is not explained. We continue to ask “What is Gravity?” Quantum mecha...

摘要:The principles of relativity and uncertainty represent two of the deepest and most encompassing propositions of the physical sciences. Indeed, much of our present knowledge of nature can be recapitulated in these important statements about the processes of motion and measurement....

摘要:Data extracted from the Atomic Data and Nuclear Data Tables [S. Raman et al ., At. Data Nucl. Data Tables 78 , 1 (2001)] are used for the calculation of magnetic moments of atomic nuclei. However, in October 2018, the author discovered that when nuclear theorists use Raman’s...

摘要:In equilibrium thermodynamics systems can be described in terms of properties which are either (1) intensive, (2) extensive, or (3) neither intensive nor extensive. While they can vary with spatial location in nonequilibrium systems, intensive properties are homogenous functions ...

摘要:The paradox of the asymmetry in time, aka the arrow in time, is an artifact of the way in which the paradox is generally framed. It is said that for every disordering (entropy increasing) trajectory of the entropy through time in a confined, isolated macroscopic, system, there is...
