Transcript of Quantum Physics

An Introduction to Quantum Physics
Composite and Elementary Particles
When we were young, we were told that everything was made up of atoms and that it was the smallest thing in existence. Particles that are made up of smaller particles are composite (protons, neutrons), while elementary particles are particles that cannot be broken down any further (electrons, photons, gluons, etc.)
The Quantum Theory
The Quantum Theory is the study of how things work and react at a microscopic/subatomic level, while also effecting things at the macroscopic level (visible to the eye). These studies and behaviors follow many different laws and theories, such as Heisenberg's Law of Uncertainty, Planck's Constant, Schrodinger's Cat, Newton's Law of Motion, etc.
-Photons (light)
-Protons (2 up, 1 down quark)
-Electrons (electromagnetism)
-Neutrons (2 down, 1 up quark)
-Quarks
-Leptons
-Bosons
-Gluons (the "glue" particles)
A Quick Review on the Atomic Theory
As we all may have learned in science, an atom is made up of three main types of sub-atomic particles. These are the protons, neutrons, and electrons. But what if I told you that the proton and neutron can be further broken down?
Are You Ready?

Now that we are familiar with the basis of the Atomic Theory and how it links to Quantum Physics, let's get started for real shall we?
The End. Thanks For Watching!

Common Subatomic Particles
Ernest Rutherford
J.J. Thomson
James Chadwick
Max Planck
The Planck's Constant is a physical constant that measures: 6.62606957 × 10-34 m2 kg / s

Heisenberg's, Schrodinger's, and More
Heisenberg's Law of Uncertainty
-The wavelength/momentum of a particle cannot be measured if the location of the particle is known.

-The location of the particle cannot be measured if the wavelength/momentum is known.

-This is due to the particle moving at a constant, and has been proven in mathematics.
Schrodinger's Cat

A cat is placed in a black box with a glass of highly corrosive chemical. A series of complex mechanisms determines whether the glass will tip or fall or not. But in quantum physics, while the box is unopened, the cat is both dead and alive. Only when the box is opened does the observer find a single result. When this happens, two realities/dimensions are created, one where the cat is dead, and one where the cat is alive.
The Higgs Boson
The Higgs Boson is a particle recently proven to exist, which spans the universe infinitely (like H2O molecules in water) in the form of a 3-D field much like the EM field. The Higgs Boson gives most elementary particles their mass, otherwise particles would be flying everywhere at the speed of light (approx. 300 million m/s) and we wouldn't be able to exist.

The Standard Model
Dark Matter?
Dark Matter is a partially proven
theoretical particle that effects galaxies and their
formation. Although it has mass and gravitational force, the dark matter particle does not react with photons (light) in any way, therefore they are completely invisible. The only way to detect these dark matter particles is through extremely complex experiments (although none have yet to succeed), and gravitational lensing.
