What is quantum physics?

My investigations tell me that Quantum Physics is the branch of science that deals with discrete, indivisible units of energy called quanta as described by the Quantum Theory. There are five main ideas represented in Quantum Theory. Quantum physics is very complicated.

I looked at quite a few websites on Google which say that they will explain it easily, but the only one I could even begin to understand is priceandobservatory. Com (link below) and even this article needs to be read through several times to try and get the hang of it! This article on the site is actually called Quantum Physics made easy.

Take a look at this and see what I mean, I hope you will be more enlightened than I am! "Quantum Physics made easy Written by keith grice Introduction to Quantum Mechanics Our world can be divided into 3 levels, Microscopic, Mesoscopic, Macroscopic levels At each level we perceive matter differently. Mesoscopic level is where we live, is at which our normal life goes about.

Macrosopic level is where stars and planets live. Make a guess, what laws of physics govern the Mesoscopic Level? Bingo!

They are Newton's 3 laws of Mechanics. The acceleration of an object is proportional to Force applied to it. F = ma Now what laws of physics govern the Macrosopic Level?

This one is what you could only learn in University. The answer is General Relativity. The theory discovered by A.Einstein.

General Relativity says that space is NOT FLAT! What do you mean that space is NOT FLAT? Imagine you draw a straight line on a world map, from New York to Shanghai.

Now imagine what the straight line would be like, if you have drawn it on the Earth. It is no longer a straight line but a curve traversing half a sphere connecting the two cities. You see space is not flat at all.

The same thing happens in outer space, between star and star. Quantum Mechanics is the physics governing the microscopic level, the level where atoms and elementary particles live. Imagine a coin lying on the table, it could only be one of the two possibilities: HEAD or TAIL.

But for a coin rotating on the table, how would you describe it? Your best answer is that the coin is 50% HEAD and 50% TAIL. Quantum Mechanics say this is precisely what happen at microscopic level.

That you are not 100% sure, what happens to an atom. You can only tell how much chance it could turn out to be this way, and how much chance it could turn out to be that way. A Mesocopic object, like a car, can have only one value of Energy at each instant.

If a 500kg car is traveling at 5 metres per second, the Kinetic Energy is (1/2) times 500kg times (5 metres per second) squared. But a Microscopic object can have more than one value of Energy at each instant! It is possible that an atom has 1 calorie, 5 calories, 10 calories Energy value at the same time!

All you need to find out is the chance, the probability of the atom being in each Energy value. Imagine a person walking from home to school, how many paths is he taking? Note, I am asking how many paths he is taking NOT how many paths he can take.

The answer is ONE of course, he could have taken a shortcut, he could have wandered around the neighbourhood, he could have chosen a zig-zag-like fanciful way of walking. The point is, once he has made up this mind, now he is on his way to school, he is taking only ONE path. This is not happening to an atom which is a billion times smaller than us.

The atom is taking multiple paths when moving from one point to one point! When you observe it, the atom will appear to be at one point, for you! When you do not observe it, the atom appears everywhere again, countless possibilities.

Bizarre? That's Quantum Mechanics. " So now you know, or not as the case may be!

I have attached a video on the off chance that it may make things clearer!

Quantum physics, the most counter-intuitive field of physics, is a branch of science that deals with discrete, indivisible components of energy termed quanta as explained by the quantum theory. The principles of quantum physics, which is the study as well as analysis of the behavior of matter and energy at the atomic, molecular, nuclear, and even minor microscopic levels, are being applied in a growing number of fields, including quantum computing, quantum optics, quantum cryptography, and quantum chemistry. Quantum physics may look as if complicated as well as difficult, mainly if one fails to remember the ‘large picture’ and gets lost in the details.

Nevertheless, it can turn out to be clearer and less complex if one applies some basic concepts so that simplified methodologies can become apparent and anticipated orders of magnitude become clear.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
