173Derivation of gravitational time dilation from principle of equivalence and special relativityScience and Philosophy 9 (1): 55-60. 2021.General relativity is the exact theory of gravity which has been experimentally found to be correct with extremely high accuracy. One of the most surprising predictions of the general theory is that time runs slow in a gravitational field. Its proof formally comes from Schwarzschild metric which is a solution of Einstein field equation for a spherically symmetric mass. However, as Einstein field equation is too complex, attempts have been made earlier to derive gravitational time dilation by dir…Read more

177A model for the solution of the quantum measurement problemScience and Philosophy 7 (2): 59-70. 2019.The basic idea of quantum mechanics is that the property of any system can be in a state of superposition of various possibilities. This state of superposition is also known as wave function and it evolves linearly with time in a deterministic way in accordance with the Schrodinger equation. However, when a measurement is carried out on the system to determine the value of that property, the system instantaneously transforms to one of the eigen states and thus we get only a single value as outco…Read more

452Origin of Quantum Mechanical Results and Life: A Clue from Quantum BiologyNeuroquantology 16 (4): 26-33. 2018.Although quantum mechanics can accurately predict the probability distribution of outcomes in an ensemble of identical systems, it cannot predict the result of an individual system. All the local and global hidden variable theories attempting to explain individual behavior have been proved invalid by experiments (violation of Bell’s inequality) and theory. As an alternative, Schrodinger and others have hypothesized existence of free will in every particle which causes randomness in individual re…Read more

292A new approach in classical electrodynamics to protect principle of causalityJournal of Theoretical Physics and Cryptography 5 1-4. 2014.In classical electrodynamics, electromagnetic effects are calculated from solution of wave equation formed by combination of four Maxwell’s equations. However, along with retarded solution, this wave equation admits advanced solution in which case the effect happens before the cause. So, to preserve causality in natural events, the retarded solution is intentionally chosen and the advance part is just ignored. But, an equation or method cannot be called fundamental if it admits a wrong result (t…Read more

282A simple proof of Born’s rule for statistical interpretation of quantum mechanicsJournal for Foundations and Applications of Physics 4 (1): 24-30. 2017.The Born’s rule to interpret the square of wave function as the probability to get a specific value in measurement has been accepted as a postulate in foundations of quantum mechanics. Although there have been so many attempts at deriving this rule theoretically using different approaches such as frequency operator approach, many-world theory, Bayesian probability and envariance, literature shows that arguments in each of these methods are circular. In view of absence of a convincing theoretical…Read more

1671Reformulation of Dirac’s theory of electron to avoid negative energy or negative time solutionJournal of Theoretical Physics and Cryptography 13 1-4. 2017.Dirac’s relativistic theory of electron generally results in two possible solutions, one with positive energy and other with negative energy. Although positive energy solutions accurately represented particles such as electrons, interpretation of negative energy solution became very much controversial in the last century. By assuming the vacuum to be completely filled with a sea of negative energy electrons, Dirac tried to avoid natural transition of electron from positive to negative energy sta…Read more
