Quantum Physics: Understand the Basics

Quantum Physics indicates the existence of alternate realities beyond our everyday concepts and logic.

What is Quantum Physics?

Quantum Physics is the part of physics that describes the very smallest things in the universe, such as molecules, atoms, sub-atomic parts such as electrons, protons, and neutrons. It is fascinating because everybody around us, including us, is made from Quantum Physics.

The terms Quantum Physics and Quantum mechanics are also interchangeably used, as they refer to the same thing.

Quantum Physics Features

• Wave-Particle duality
• Superposition
• Entanglement
• Observer effect

Real-Life Applications

It is arguably the most successful scientific theory out there that finds applications in computers, digital cameras, lasers, led screens, MRI machines, nuclear power plants.

• X-Rays and Scattering of other types of waves (wave-particle duality)
• Photoelectric effect (wave-particle duality)
• Quantum cryptography / teleportation (quantum entanglement)
• Quantum computing (quantum superposition)
• Predicting the future / Retrocausality ( observer effect)

Wave Particle Duality

Wave–particle duality is a concept in quantum mechanics which says that particles (light and matter) can be described as either a particle or a wave.

We can see wave-particle duality exists in nature. Under some experimental conditions, a particle appears to act as a particle, and under different experimental conditions, a particle appears to act a wave.

Watch: Quantum Physics Basics

The best lectures on quantum physics and quantum computing are available here by a University of California professor. However, these are a bit mathematical requiring knowledge of linear algebra concepts.

Observer Effect

One of the most bizarre premises of quantum theory

Has long fascinated philosophers and physicists alike

By the very act of watching, the observer affects the observed reality.

Irrespective of the technology used

Interference (and wave behaviour of light) can only occur when no one is watching.

Once an observer begins to watch for which of the openings the particle is going through, the wave property switches off.

This happens because the light would give away the secret of its real nature.

The interference pattern also disappears in such a case.

The greater the amount of ‘watching’, the greater the observer’s influence on what actually takes place.

In an experiment conducted by the Weizmann Institute in Israel

The quantum “observer’s” capacity to detect electrons could be altered by changing its electrical conductivity, or the strength of the current passing through it.

When the ‘observer’s’ capacity to detect electrons increased, the interference weakened

When the ‘observer’s’ capacity to detect electrons was reduced, the interference increased.

The interference pattern adjusted itself just enough that the experiment would not be successful, as if mocking us

Who was making this adjustment?????

NOTE: The phenomenon is experimentally repeatable

Quantum Physics and Veda

Dr. John Hagelin (Ph.D. Quantum Physics) says the scientific world is moving towards the study of the Unified field and their observations are already been mentioned in the Vedas.
