Model of the QM atom
= Schrodinger Equation =

Formulated in 1926 by Austrian physicist Erwin Schrodinger, this is an equation that describes how the quantum state of a physical system changes in time. It is as essential to quantum mechanics as Newton’s laws are mechanics.

The most general form is the Time-Dependent Schrodinger Equation, which gives a description of a system evolving with time. For systems in a stationary state, this equation is sufficient. Approximate solutions to the to this equation is commonly used to calculate energy levels and other properties of atoms and molecules. Sources: http://en.wikipedia.org/wiki/Schr%C3%B6dinger_equation

Building the Bomb
The Manhattan project was the code name of the US’s attempt to build an atomic bomb. The efforts were started in 1938. This project was started because many feared that the Germans would create an atomic bomb before the United States because they had achieved fission. Many of the world’s greatest scientists were involved in the building of the atomic bomb including Albert Einstein. In 1945 the scientists were able to create a working bomb. Albert Einstein, Enrico Fermi, Richard Feynman, J. Robert Openheimer, and Harold Urey. Also President FDR, and Hoover. 1938-1945 The explosion was created through a series of reactions that cause explosions that change the atoms. The changed atoms then release even more energy.

Quark Theory
__Quark__- an elementary particle and a fundamental constituent of matter. Quarks combine to create composite particles called hadrons. The most stable of these are protons and neutrons. Quarks are never found in isolation. They can only be found with hadrons. This is because of a phenomenon known as color confinement. There are six types of quarks, known as flavors: up, down, charm, strange, top, and bottom. Up and down quarks have the lowest masses. Through a process known as particle decay, the heavier quarks rapidly change into up and down quarks. Up and down quarks are generally stable and most common in the universe. Charm, strange, top, and bottom quarks can only be produced in high energy collisions. Quarks have various natural properties, including electric charge, color charge, spin, and mass. Quarks can experience all four fundamental interactions (electromagnetism, gravitation, strong interaction, and weak interaction.)
 * What are they?**

The quark model was independently proposed by physicists Murray Gell-Mann and George Zweig in 1964.
 * Who was involved with the discovery? When?**

Quarks relate to the atom because they combine to form composite particles called hadrons. The most stable of hadrons are protons and neutrons, which are the components of atomic nuclei.

Heisenberg Uncertainty Principle
What is it?

States by precise inequalities that certain pairs of physical properties, such as position and motion. This means that the more precisely one property is measured, the less precisely the other can be measured. Werner Heisenberg published it in 1927. The principle means that it is impossible to determine simultaneously both the position and momentum of an electron or any other particle with any great degree of accuracy or certainty.

How does it relate to the atom?

It relates to the atom by determining simultaneously both the position and momentum of an electron or any other particle with any great degree of accuracy or certainty.
