Quantum Physics And Major Findings In The Field

Physics is a subject which is considered dry and the gift of a few intelligent brains by students. Quantum Physics like topics are actually interesting to learn and students can learn them with fun through the interactive methods of online Physics tutors.

What is Quantum Physics?

Quantum Physics is the study of matter and energy at the nuclear, atomic, molecular and microscopic levels. It was found out in the earlier 20TH century that the laws that govern macroscopic objects do not function the same at microscopic level.

Meaning of Quantum

Quantum means “how much” in Latin language. It refers to the discrete units of energy and matter that are predicted by and observed in Quantum Physics. It explains that even space and time which are extremely continuous have smallest values possible.

How Quantum Mechanics was developed

When scientists tried to measure with greater precision through technology, they observed strange phenomena. The concept of Quantum Physics was born with Max Planck’s 1900 paper on Blackbody Radiation. It was further developed by Albert Einstein, Niels Bohr, Erwin Schroedinger and others.

What is special about Quantum Physics?

In the field of Quantum Physics, observing something influences the physical processes that take place. Light waves can act like particles and particles can act like waves which is called wave particle duality. Matter can go from one spot to another without moving across the intervening space. Information moves across vast distances immediately. In Quantum Mechanics, we can find out that the entire world is a series of probabilities. When dealing with larger objects, it breaks down as seen in Schroedinger’s Cat thought experiment.

Subfields of Quantum Physics

Quantum Entanglement

Quantum Entanglement describes a situation where multiple particles are associated in a way that measuring the quantum state of one particle places constraints on the measurements of other particles. This is very well exemplified by EPR Paradox. This concept has been confirmed through tests of Bell’s Theorem now.

Quantum Optics

Quantum Optics focuses on the behavior of light or photons. At the level of Quantum Optics, the behavior of individual protons has a bearing on the out coming light as opposed to classical optics developed by Sir. Isaac Newton. Lasers are the application born out of Quantum Optics.

Quantum Electrodynamics

Quantum Electrodynamics studies how photons and electrons interact. It was developed by Richard Feynman, Sinitro Tomonage, Julian Schwinger and others. The predictions of QED regarding the scattering of photons and electrons are accurate to 11 decimal places.

Unified Field Theory

Unified Field Theory includes research methods which try to reconcile Quantum Physics with Theory of General Relativity by Einstein. Quantum Gravity, Grand Unified Theory, Theory of Everything and String Theory are some of the Unified Field Theory.

Quantum Physics is otherwise known as Quantum Mechanics or Quantum Field Theory. It is an essential aspect of Physics learning. Those who find the topic surmounting can chat with a live Physics tutor online and learn the topic with ease. The personalized tutoring sessions of online tutoring sites help students learn such Physics topics without struggle.
