What is empty space What is matter   Homework 6 due April 10 Term paper draft due April 17 Classical world we have found portions of matter with changeless forces indestructible qualities and called them elements The only changes that can remain possible in such a world are spatial changes movements SO at last the task of physics is to refer phenomena to inalterable attractive and repulsive forces whose intensity varies with distance The solubility of this problem is the complete comprehensibility of nature Helmholtz 1890.

Isfahan University of Technology - Quantum Mechanics in Nanotechnology - October 8-9, 2014. By: Miles H. Taylor. The EPR Paradox. In 1935, physicists Albert Einstein, Boris . Podolsky. , and Nathan Rosen created a thought experiment that was supposed to show a lack of completeness in quantum mechanics, a relatively recent creation at the time. The thought experiment, later called the EPR paradox after the last names of the creators, was based upon a paradox they saw in the quantum entanglement idea of quantum mechanics regarding the fact that one cannot know observables from different sets. They began by imagining two physical systems that interact when created, so that they will be defined by a single quantum state (Blanton). In other words, one must begin by imagining two entangled particles. Even when separated, the two systems will still be described by the same wave function, no matter the distance between them, as they are still entangled. If someone measures an observable, such as the spin if the systems are photons, of one system, it “will immediately determine the measurement of the corresponding observable in the second system” (Blanton). This applies even at distances that special relativity should prohibit. Imagine that the two systems are light-years apart. According to quantum mechanics, measuring an observable in the first system forces the corresponding observable in the other system into a well-defined state immediately, despite the fact that they are not close enough to have an effect on one another. The information between the two has passed much too fast for the distance under the theory of relativity. This left two options for Einstein, . Harrison B. Prosper. Florida State University.
