A user on PhysicsForums shared their journey of exploring theoretical physics, expressing a deep interest in the universe and a desire to understand complex concepts like black holes. They have written a lengthy essay based on their learning from YouTube and are seeking guidance on the requirements to become a theoretical physicist. Responses from the community emphasized the importance of formal education in mathematics and physics, advising against relying solely on YouTube for learning. Recommendations included studying calculus, algebra, and physics through books and structured resources like Khan Academy. The discussion highlighted the need for a solid mathematical foundation, as well as the reality that theoretical physics involves rigorous problem-solving and may not align with romanticized perceptions of science. Overall, the consensus was that while initial interest can stem from casual sources, serious study and discipline are essential for a career in physics.
