Understanding the Quantum World

By: Shrawaya Kapoor

Quantum Mechanics is a branch of physics that deals with waves and particles and their behaviour when not observed. The laws of classical physics don’t properly apply in Quantum Mechanics. Some notable scientists who excelled in the field of Quantum mechanics is Max Planck, Erwin Schrödinger Schrodinger, Werner Heisenberg, and Richard Feynman Schrodinger. This theory suggests that an object can be in multiple states simultaneously until observed.  For instance, we put a cat in a box with a radioactive particle that has a 50% chance of decaying. The particle that can kill the cat is in a quantum Superposition, meaning the cat is both alive and dead at the same time until observed.

Heisenberg uncertainty principle: This theory tells us that we cannot measure the exact position and momentum of an object at the same time. For example, a person needs to travel from position A to position B , when he is standing still, we can tell his position but not momentum as he is not in motion, but when the The person is walking to position B, he has momentum, but not a fixed position as he is in motion Quantum field: An invisible field that fills all of space, it It is made up of tiny particles and forces that interact with each other. It is a fundamental concept in physics That helps explain how particles behave and interact at a quantum level.

Quantum entanglement: When two particles are connected by a mysterious force that causes them to feel the same thing happening to the other particle, no matter how much distance is between them. Observer effect: Particles behave differently when Observed.

Quantum tunneling: In classical physics it’s not possible for particles to pass to potential barriers, but on Quantum mechanics particles can pass through barriers due to their wave-particle duality, like nature. This phenomenon is mostly seen in low-mass particles such as electrons or protons.

Important points:

A particle can be both a wave and a particle.

Particles behave differently when observed.

We cannot measure the exact momentum and position of an object simultaneously.

Quantum objects can exist in multiple states simultaneously until observed.

Quantum Mechanics is a fascinating and mysterious branch of physics. Which remains unknown to several scientists.
