Bohmian Mechanics Revisited
We consider the problem of whether there are deterministic theories describing the evolution of an individual physical system in terms of the definite trajectories of its constituent particles and which stay in the same relation to Quantum Mechanics as Bohmian Mechanics but which differ from the latter for what concerns the trajectories followed by the particles. Obviously, one has to impose on...
متن کاملClassical Mechanics Revisited
Two linear algebra based strategies are presented to deal with general classical mechanics problems with constraints. Classical concepts such as holonomic and nonholonomic constraints, virtual displacements, principle of virtual work, Hamilton’s principle and method of Lagrange multipliers are critiqued.
متن کاملNelsonian Mechanics Revisited *
In de Broglie and Bohm’s pilot-wave theory, as is well known, it is possible to consider alternative particle dynamics while still preserving the |ψ| distribution. I present the analogous result for Nelson’s stochastic theory, thus characterising the most general diffusion processes that preserve the quantum equilibrium distribution, and discuss the analogy with the construction of the dynamics...
متن کاملCardiac mechanics revisited: the relationship of cardiac architecture to ventricular function.
The keynote to understanding cardiac function is recognizing the underlying architecture responsible for the contractile mechanisms that produce the narrowing, shortening, lengthening, widening, and twisting disclosed by echocardiographic and magnetic resonance technology. Despite background knowledge of a spiral clockwise and counterclockwise arrangement of muscle fibers, issues about the exac...
متن کاملEarly Gedanken Experiments of Quantum Mechanics Revisited
The famous gedanken experiments of quantum mechanics have historically played crucial roles in trying to understand quantum mechanics and in developing the Copenhagen interpretation. They are re-examined here from the perspective of standard quantum mechanics, without a mix of any ontological interpretation. It is shown that, in most of these gedanken experiments, entanglement plays a crucial r...
