Physics Of Quantum Mechanical Experiments - 1337 Words

We’ve already discussed some of the experimental phenomena that inspire competing interpretations or theories of what’s going on in the real world during quantum-mechanical experiments. (In brief: Observing microscopic particles seems to either: cause them to randomly take one result or the other; create a branching world for every possible outcome; or require hidden variables and allow for faster-than-light, nonlocal communication. Particles seem not to take one path, not the other, not both, and not neither, and even act as if they â€Å"know† when we’re observing them.) In this final installment of a three-article series, we’ll look in very broad strokes at some of the philosophical implications of these views of quantum mechanics. I. Logic Standard logic is two-valued. That just means that each sentence in the logic is true or false, not both, and not neither. ‘My cat’s breath smells like cat food’ is either true or false; it can’t both smell that way and not smell that way at the same time to the same person, and surely it either does or it doesn’t. But as we’ve seen, some interpretations of quantum mechanics might suggest adding in a new value.1 Perhaps Copenhagen-style interpretations indicate that we should have a value of neither—a truth-value â€Å"gap†Ã¢â‚¬â€and Copenhagen and many-worlds interpretations indicate that we should have a value of both: a truth-value â€Å"glut.†2 As it happens, there are independent philosophical reasons to explore three- or four-valued logics (andShow MoreRelatedTaking a Look at DNA Supercoiling684 Words   |  3 Pagesleft direction. The laws of Physics govern everything that happens in the world, including DNA coili ng in living beings. Some of the concepts in Physics that are involved in DNA coiling are quantum mechanics and statistical mechanics. Quantum physics is a branch of physics that explores certain units of energy, which are called quanta. These units of energy are described by the Quantum Theory.

It attempts to describe and account for the properties of molecules and atoms and their constituents—electrons, protons, neutrons, and other more particles. This type of physics beginning as a set of controversial mathematical explanations of experiments that the math of classical mechanics could not explain. It began at the turn ofRead MoreThe Theory Of Louis De Broglie865 Words   |  4 Pagespassed away in March 1987. He achieved a degree in science in 1913 before being conscripted into military service from 1914 to 1918. After the war de Broglie continued his education specializing in theoretical physics in the study of quanta. In 1924, de Broglie delivered a thesis on the quantum theory earning him a Doctorate degree. The thesis contained a series of findings which were confirmed in 1927 by the discovery of electron diffraction.

In the paper by Bohm, he shows how one could conceive of an experiment to mirror the conceptual situation put forth in the EPR paper, by examining the dissociation of a diatomic molecule whose total spin angular momentum is zero. For example, the hydrogen molecule into two hydrogen atoms. In the experiment, the hydrogen atoms would separate after interaction, in different free directions. It is here that an experimenter would measureRead MoreTwo Forms of the Generalized Uncertainty Principle1323 Words   |  6 PagesVarious theories of quantum gravity predict the existence of a minimum length scale, which leads to the modification of the standard uncertainty principle to the Generalized Uncertainty Principle (GUP). In this paper, we study two forms of the GUP and calculate their implications on the energy of the harmonic oscillator and the Hydrogen atom more accurately than previous studies. In addition, we show how the GUP modifies the Lorentz force law and the time-energy uncertainty principle. 1.

However, after an experiment performed by physicist Ernest Rutherford in 1909, Thomsons Plum-Pudding Model would become outdated. Ernest Rutherford studied alpha particles or small pieces of positively charged matter. In an experiment, he fired alpha particles at a piece of gold foil, with a zinc sulfide screen behind it that would glow revealing the path of the alpha particleRead MoreThe Ultimate Test For Any Idea1401 Words   |  6 Pagescompatible with reality. In physics, reality is the direct result of an experiment; thus, we are forced to think about reality as â€Å"observable reality†. In fact, the distinction between reality and observable reality is extremely important, since as a consequence of this distinction, a logically correct theory may not necessary be correct while a logically non-satisfying theory may be completely correct (if it is also able to predict the result of a series of experiments). Reality can encompasses anyRead MorePhysics : Physics And Physics1859 Words   |  8 PagesIn short, quantum mechanics is ‘a mathematical framework that plays a huge role in modern phys ics and chemistry’. It was interpreted in many ways, however the Copenhagen Interpretation was the most widely held view, largely developed by Danish physicist Neils Bohr who worked in Copenhagen. The framework can be applied to different scientific phenomena and can be used to investigate the behaviour of the building blocks of the universe, all elementary particles.

Quantum teleportation was first demonstrated with entangled photons[11] in 1997. Later, various developments have been achieved in laboratory, including the demonstration of entanglement swapping[12], open destination teleportation[13] and teleportation of two bit composite system[14]. Entanglement distribution has been shown with fiber links[15–18]. In addition, â€Å"practical† quantum teleportation have been realized via fiber links[19
