What is quantum physics

What is quantum physics

Quantum physics studies the behavior of matter and energy at the smallest scales, typically at the level of atoms and subatomic particles like electrons, protons, and neutrons.

Electrons exist in cloud-like regions called orbitals around the nucleus, which is composed of protons and neutrons. The exact position of an electron isn't a fixed orbit but a probability distribution within these orbitals.

Heinsenberg Principle Of Uncertainty

Heinsenberg Principle Of Uncertainty

The Heisenberg principle of uncertainty states that you can’t simultaneously know with high precision both the position and momentum of a particle. 

If you know the position, you won’t know the exact momentum and vice-versa.

This is due to the act of measurements induced on the phenomenon being observed.

For example, if we use a specific laser to know the exact position of an atom, the laser would also influence the momentum and we won’t know it.

Translation in everyday life:

Focusing solely on one thing, will distort your ability to have accurate information on the other things.

<p>An atom is in a multi state...

An atom is in a multi state called ‘superposition’ until you observe it. That’s the only way to know the actual state.

Schrödinger's cat is a thought experiment that places a cat in a black box with poison that gets activated upon the decay of a radioactive atom.

What is the state of the cat?

It is both dead and alive simultaneously (demonstrating the superposition principle), until you open the box and see for sure.

Translation in everyday life:

Do not place your cat in such a box.
