Online courses to learn physics
Q: Is it possible to self-study physics from books and online courses to become a physicist?
A: Honestly? It is almost impossible.
To become a professional physicist you need at least eight years of daily intense study. Are you sure you want to spend all this time studying physics?
Additionally, professional physicist are formed in an academic environment where they interact all day with teachers and classmates. This allows them to improve every single day during eight years.
That's the truth. Don't be delusional.
However, you can learn a lot of physics with the right material and guidance from an online teacher. Myself I teach physics and mathematics online and I can assure you that my students know more particle physics and general relativity than many professional physicists.
Now, don't try to learn everything by yourself without any help; you will waste your time and end up frustrated.
