I don't know string theory after reading Brian Greene
In all seriousness
I always thought
QM->QFT(and QED)->?
QM, or quantum mechanics, is a theory that describes the behavior of particles at a microscopic level. QED, or quantum electrodynamics, is an extension of QM that specifically deals with the interactions between particles and electromagnetic fields.
The amount of self-study you should do in QM and QED depends on your personal goals and level of understanding. It is recommended to have a strong foundation in mathematics, particularly calculus and linear algebra, before diving into these subjects. It is also helpful to have a basic understanding of classical mechanics and electromagnetism.
QM and QED have a wide range of applications in various fields such as chemistry, physics, and engineering. They are used to understand the behavior of subatomic particles, to develop new technologies such as transistors and lasers, and to design new materials with specific properties.
It is important to have a structured approach when self-studying QM and QED. Start with a good textbook that covers the fundamentals and follow a study plan. Practice solving problems and seek help from online resources or a tutor when needed. It is also beneficial to join study groups or forums to discuss and clarify concepts with others.
Self-studying QM and QED can be challenging due to the abstract concepts and complex mathematical equations involved. It also requires a strong understanding of advanced mathematics and may require a significant amount of time and effort to grasp the material. Additionally, finding reliable resources and staying motivated can be difficult when studying on your own.
