Quantum mechanics is a form of physics used to study very small objects such as atoms. Many people have heard of quantum mechanics, whether from a book or a television show. Automatically people think "nerd" or "geek", which is about right, but these people themselves have no idea how quantum mechanics has improved their lives or even how it works. This may seem difficult, but it's really not that difficult to understand. So now it's time to answer the important question everyone wants to know. What is this? Quantum mechanics is not the study of small things like cells or microbes. It is the study of even smaller things called particles. The main reason we have quantum mechanics is that it replaces classical physics to describe events and actions that occur with particles and other objects on a very small scale (Tavolacci). We use quantum theory because Newton's laws cannot accurately explain what happens to objects on smaller scales. Quantum physics has therefore helped scientists to understand a little more about the particles that make up the world (Tavolacci). Quantum theory states that all matter, energy and radiation are made up of small beams called quan (or plural quanta), hence the name “quantum” mechanics (Tavolacci). The theory also states that electrons move in a defined wave instead of just flying around the nucleus of an atom, because if they were floating aimlessly, the electrons would collide with the nucleus in a fraction of a second and all matter that we know would cease. exist (McCoy). Electrons stay in certain waves depending on their energy level. It's much easier to think of this whole process of acting like a solar system. All the electrons are moving... middle of paper... here the electrons are moving and going away. Photons of light carry energy and strike the electron, which transfers energy to the electron but slows the photon. Finally, in the 1920s, scientists discovered wave-particle duality. Wave-particle duality asserted that light had both the properties of a wave and the properties of a particle (Tavolacci). Quantum mechanics has been around for at least a century and for about half of those years it has been widely rejected. When scientists finally realized its potential, they opened up to the idea and began creating many new experiments and discovering the big answers to life's biggest questions. Scientists will continue to make incredible advances in quantum mechanics and may one day find a way to improve our lives with some of the best technologies humanity has ever seen..
