Quantum - Learn Quantum Mechanics & Test Knowledge

Are you aware of a realm where objects can exist in countless locations simultaneously? A realm where determining the precise location of an object is impossible, no matter how much effort you put in? A realm where items situated at opposite ends of the cosmos can communicate without delay? A realm where certainty is elusive because everything hinges on probability?

Welcome to the intriguing and often debated universe of quantum mechanics, which stands out as perhaps the most fascinating physical theory ever conceived!

The quantum subject includes:

• A comprehensible articulation of key phenomena in quantum mechanics, organized into 13 chapters

• 60 assessment questions categorized into 4 tests, allowing you to evaluate your understanding of quantum mechanics

INTRODUCTION

Motion. At first sight it is something incredibly uninteresting and trivial. 

People have been studying motion for thousands of years, but it was not until 1687, when Isaac Newton formulated his three laws of motion, that people finally started to understand it more deeply. Newton’s laws of motion were so ahead of their time that some scientists still consider Newton the most revolutionary physicist of all time. 

But even Newton’s laws are not perfect, and in 1905 came the special theory of relativity, which brilliantly describes the motion of objects moving at high speeds, formulated by Albert Einstein.

But there is another theory that started to develop at the same time. A theory that completely changed our perception of reality. 

In 1900, the cornerstone of quantum mechanics was laid.

Quantum mechanics deals with objects from the so-called microworld, like particles or atoms. These objects behave nothing like objects of “classical” proportions from the so-called macroworld we ordinarily deal with, and thus cannot be described by classical physics.

In this app, you will be able to explore the world of this ground-breaking theory.

And if you at any point struggle to comprehend some its peculiar phenomena, do not worry, you are not the only one.

Richard Feynman, one of the greatest contributors to quantum mechanics, once said:

“I think I can safely say that nobody understands quantum mechanics.”

A) Moving at very high speeds

B) Of very small sizes

C) In strong gravitational fields

D) Of macroscopic sizes

ANSWER:

Quantum mechanics deals with objects of very small proportions, such as atoms

or subatomic particles.

A) 1850

B) 1950

C) 1800

D) 1900

ANSWER:
