Heisenberg’s Uncertainty Principle as a Criterion of Truth in Science and Philosophy
Abstract: Werner Heisenberg discovered the fundamental uncertainty relation: the simultaneous accurate measurement of the errors of two variables characterizing the two parameters of quantum mechanical system is impossible. The Heisenberg uncertainty principle became one of the cornerstone principles of quantum mechanics and a consequence of the content of wave-particle duality. Another more important interpretation of the uncertainty principle is the following conclusion: the more precisely one characteristic of a quantum mechanical …

Non-Newtonian Power-law Fluid Flows for Shear Thinning Viscosity in a T junction Channel
Abstract: In this paper, non-Newtonian fluid flow behaviors are analyzed in a two-dimensional T junction channel using Lattice-Boltzmann Method (LBM). The LBM has been built up on the D2Q9 model, and the single-relaxation-time (SRT) method called the Lattice-BGK (Bhatnagar-Gross-Krook) model. The flow patterns are analogous to blood flows in branched arteries for T junction flows. Firstly, the code validation has been occurred for the Newto-nian fluid flows by comparing the accessible …
