Is it possible to learn theoretical physics, including quantum mechanics and relativity, through self-taught methods such as internet resources?

Unlocking the Doors to Theoretical Physics

Yes, it is absolutely possible to learn theoretical physics, including quantum mechanics and relativity, through self-taught methods and internet resources. Numerous individuals have successfully embraced this path. Whether you're curious about the fundamental forces of the universe or fascinated by the subtle intricacies of quantum mechanics, the internet offers a wealth of resources to equip you with the knowledge and skills necessary for self-study.

Foundational Knowledge: Mathematics and Classical Mechanics

Proceeding with theoretical physics without a solid foundation would be akin to attempting to build a skyscraper on sand. Here are the essential steps and resources to get you started:

1. Mathematics

A robust understanding of mathematics is vital for grasping the nuances of theoretical physics. Focus on the following areas:

Calculus: Multivariable and single-variable calculus Linear Algebra Differential Equations Complex Numbers and Functions

There are plenty of online courses, textbooks, and tutorials to help you master these topics. Consider enrolling in courses on platforms like Coursera, edX, and Khan Academy.

2. Classical Mechanics

Before delving into the realms of quantum mechanics and relativity, it's crucial to have a strong foundation in classical physics. Familiarize yourself with concepts such as Newtonian Mechanics, Lagrangian and Hamiltonian formulations, and the laws of motion. MOOCs and online resources can significantly enhance your understanding.
