 # How To Self-Learn Quantum Mechanics (Advanced Guide)

Quantum mechanics is an advanced branch of physics about the smallest elements and particles of our universe. While it’s a common choice in university, you may decide that you want to or need to opt to self-learn quantum mechanics instead. It can seem overwhelming, but you can do it all on your own.

Here is how you can learn quantum mechanics on your own:

1. Understand what quantum mechanics is.
2. Learn the basics of physics and math.
4. Utilize online resources.
5. Practice quantum mechanics.

No matter why you want to self-learn quantum mechanics, it’s completely doable on your own. Just follow these simple steps, and you’ll be learning quantum mechanics in no time.

## 1. Understand What Quantum Mechanics Is

Quantum mechanics is an advanced branch of physics that focuses on the smallest parts of our world.

According to the Merriam Webster dictionary, quantum mechanics is “theory of matter that’s based on the concept of the possession of wave properties by elementary particles, that affords a mathematical interpretation of the structure and interactions of matter on the basis of these properties, and that incorporates within it quantum theory and the uncertainty principle.”

In simpler terms, quantum mechanics is the study of small, physical elements like atoms, molecules, and particles and how they interact with energy and matter.

The three most basic, conceptual parts of quantum mechanics are quantized properties, particles of light, and waves of matter.

There are many reasons why you may want to study quantum mechanics, and specifically, self-learn it. But, no matter your reason, you’ll better understand our world and the smallest elements that make it when you’re done learning quantum mechanics.

## 2. Learn the Basics of Physics and Math

You can’t learn calculus without knowing basic addition, and you can’t perform Shakespeare without knowing how to read. Similarly, you won’t be able to learn quantum mechanics unless you understand basic physics. Even if you took a physics class that you think prepared you to learn quantum mechanics, you should still brush up on your knowledge of basic physics.

You also need to know some basic math if you want to learn quantum mechanics. While a lot of what you’ll be teaching yourself is conceptual, there are many mathematical elements that you need to understand as well.

This section has the best books about physics and math to prepare you to learn quantum mechanics. Make sure you’re familiar with the topics covered in these books before trying to self-learn quantum physics.
