Quantum Mechanics Part 1

The first step in learning more about Quantum Physics is understanding what Quantum Physics means. Newton was a brilliant man and was great at explaining all the big things. But as things get smaller and smaller, these classical laws of physics break down. As we get down to macroscopic matter, they posses properties unlike those of bigger objects that Newton knew of.

The basic idea behind quantum physics is that matter has both wave like and particle like properties. Quantum physics deals with these duality of matter. The history of Quantum Mechanics goes back a long way and is quite interesting.

Quantum Physics first came from further understanding of light. At first, scientists believed that light was just waves, and matter was particles. Fairley soon, they found this wasn't the case. A scientist by the name of Max Planck, often referred to as the father of quantum physics, hypothesized that energy is absorbed and emitted in quanta. This hypothesis matched the black body radiation theory. he made an equation for this transfer of energy but he never thought of these quanta as tangible objects, more of an idea of explanation.

Einstein used Planck's discovery as a means to explain the photoelectric effect. Many experiments following not only proved that quanta exists, but they also have momentum and other traits of particles. So in Summery, at a subatomic level, particles and electro magnetic waves share properties and this wave-particle duality is the basis of Quantum mechanics.
