Quantum Physics

Quantum Superposition

-Quantum waves are expressed as equations

-Describe the probabilities of an object existing in a given state or having a particular property

-The equations might provide information on the probability of an electron moving at a specific speed or residing in a certain location

-When an electron is in superposition, its different states can be thought of as separate outcomes, each with a particular probability of being observed

-An electron might be said to be in a superposition of two different velocities or in two places at once

Who was Erwin Schrodinger?

-Erwin Schrödinger was an Austrian physicist -Known as the father of quantum physics, he contributed enormously to the development of quantum mechanics by means of his equation and research in other topics, such as thermodynamics and statistical mechanics.

Who was Erwin Schrödinger?

Who was Erwin Schrodinger?

Equation:

-Erwin Rudolf Josef Alexander Schrödinger

-Austrian physicist born, raised, and died in Vienna, Austria

-Known as the father of quantum physics, he contributed enormously to the development of quantum mechanics by means of his equation and research in other topics, such as thermodynamics and statistical mechanics.

- Schrödinger won the Nobel Prize for Physics in 1933

-Discovered electrons could have the properties of either waves or particles, but are neither the one nor the other; their state can be calculated only with a degree of probability.

-He created Schrödinger's Cat

Schrödinger's Cat

- Introduced by Erwin Schrödinger in 1935 to demonstrate quantum mechanics principles.

- Experiment consists of a sealed box with a cat, radioactive atom, Geiger counter, poison, and a hammer.

- Shows the concept of quantum superposition where the cat can exist in both alive and dead states.

- Highlights the clash between classical understanding and quantum mechanics.

- Outcome of the experiment is determined only upon observation, raising questions about the role of observation.

Dual Nature of Light

The tails of the Hale-Bopp comet point away from the Sun, evidence that light has momentum. Dust emanating from the body of the comet forms this tail. Particles of dust are pushed away from the Sun by light reflecting from them. The blue, ionized gas tail is also produced by photons interacting with atoms in the comet material.

- We had long suspected that the fundamental particle of electromagnetic radiation shared properties with our more macroscopic particles

-Around 1923, Arthur H. Compton observed that X-rays reflecting from materials had decreased energy and interpreted this as being due to the scattering of the X-ray photons by electrons.

- It was once strange to think of photons exhibiting momentum, but now, it is now a well-established fact within the scientific community.

GIMKIT TIME!!!!!!!!!!!!!!!

time to suffer lmao
