The Quantum World

 The Quantum World

The quantum world is a mysterious area of science that defies understanding of the laws of classical physics and explores the behavior of matter and energy at a microscopic level. Quantum mechanics describes the behaviors of subatomic particles such as electrons, protons, and photons.

Quantum mechanics was discovered by a group of physicists in the early 20^th century. Some of the famous physicists were Max Plank, Albert Einstein, Neils Bohr, Werner Heisenberg, and Erwin Schrodinger.

                                                            

                                                  

Some mind-blowing quantum theories:

Schrodinger’s Cat

The Schrodinger’s cat was a thought experiment proposed by Erwin Schrodinger in 1935 to illustrate bizarre and counterintuitive implications of quantum mechanics.

According to his experiment, a cat is placed inside a sealed box attached to a device that can release lethal poison to kill the cat. The release of poison is triggered by a quantum event. According to his explanation as long as the box is not opened and the cat is observed, the cat and the poison are both in a state of superposition, that is they exist in multiple states simultaneously. Therefore, the cat is both alive and dead at the same time until someone opens the box to observe its condition.

 

 Quantum Entanglement

Quantum entanglement is another mind-blowing concept that was proposed by Albert Einstein, Boris Podolsky, and Nathan Rosen in 1935. Entanglement occurs when any two particles become co-related in such a way that one particle becomes dependent on the other, even if they are separated by vast distances. That means changing the state of one particle results in a change in the state of other particles as well. Entanglement has many practical applications, such as Quantum Computing, Quantum Cryptography, etc.

 

The sun cannot shine without quantum particles

The bright light that the sun emits is because of the nuclear fusion in its core. When two protons create a large particle then the identical charges repel each other (“Coulomb Barrier” termed by physicists) this causes them to give off light, thus helping the sun to shine.

 

Black hole evaporation

A black hole is a region of spacetime having an intense gravitational field where no matter, electromagnetic waves, planets, galaxy, not even light cannot escape its absorption. Even though its massive absorption ability it also radiates a type of radiation(quantum particles). This radiation(Hawking radiation) is the reason black holes slowly evaporate and the size becomes smaller. At this point, physicists could not describe them because of some knowledge gap. However, this black hole evaporation theory was given by Stephen Hawking in 1974.

In conclusion, the quantum world is a mysterious and fascinating realm that defies our understanding. Scientists such as Max Plank, Albert Einstein, Neils Bohr, Werner Heisenberg, Erwin Schrodinger, Richard Feynman, and Stephen Hawking have contributed greatly to our understanding of this field and their theories are continuously shaping the future of the quantum world.
