Quantum Physics

 At a fundamental level, quantum physics predicts very unique things about how matter works which are completely at odds with how things work in the real world. Quantum particles behave like particles, in a single place or they can behave like waves, distributed all over space or in several places at once. How they appear seems to depends on how anyone choose to measure them, and first we measure they seem to have no definite properties at all leading us to a basic conundrum about the nature of fundamental reality. That fuzziness lead to apparent paradoxe such as Schrondinger’s cat, in that thanks to an uncertain quantum physics process a cat is left dead and alive at a same time. But that is not all. Quantum particles also seem to be able to effect each other instantaneous even when they are far away from each other. This truly bamboozling phenomenon is called as entanglement, or in a phrase coined by Einstein, “spooky action at a distance”. That quantum powers are completely un...

Picture of how particles interact to make the world  Quantum physics i s the physics which explains how everything works :  the best description we have of  nature of   particles  which  make up matter and the forces with which they interact. Quantum physics means how atoms work, and so why chemistry   and  biology work as they do with it.  You, me at some level at   least, we’re all dancing to the quantum tone. If we want to explain how electrons flow through a computer chip, how photons of light get converted to electrical current in a solar panel or amplify themselves in a  laser, or  just how the sun keeps burning, you will need to use quantum physics. The difficulty and, for physicists, the fun starts here. To begin with, there is no single quantum theory. There is quantum mechanics, the basic mathematical  framework that underlies it all , which was first discovered in the 1920s by Niel'...
