How different are intro physics courses from intermediate or advanced ones?

[xbomber88]

For example what is the difference between an intro mechanics or E&M course and an intermediate level one? What about an advanced one that you would take in grad school?

The difference mostly has to do with mathematical techniques and general sophistication. For example intermediate E&M involves more advanced techniques like vector calculus and basic partial differential equations, graduate E&M requires complex analysis, Green's functions and advanced PDEs.

Sophistication is more difficult to explain but equally important, this could roughly be described as what the textbook author considers to be obvious and what is considered to be worthy of explanation.

Introductory physics courses typically cover the fundamental concepts and principles of physics, such as kinematics, dynamics, and electromagnetism. These courses are designed for students who may not have a strong background in math or science and are often taken by non-physics majors as part of their general education requirements.

Intermediate level physics courses build upon the foundational concepts learned in introductory courses and delve deeper into more complex topics, such as thermodynamics, quantum mechanics, and special relativity. These courses require a stronger background in math and physics and are typically taken by physics majors or students pursuing a related field.

Advanced physics courses, such as those taken in graduate school, are even more specialized and focus on specific subfields of physics, such as particle physics, astrophysics, or condensed matter physics. These courses require a high level of mathematical proficiency and often involve extensive research and laboratory work.

The main difference between intro physics courses and intermediate or advanced ones is the level of complexity and depth in which the material is covered. Intro courses provide a general overview of the basic concepts, while intermediate and advanced courses dive deeper into the theories and applications of physics. Additionally, the level of mathematical rigor and problem-solving skills required increases as the courses become more advanced.

In terms of specific topics, an intro mechanics or E&M course may cover basic concepts such as Newton's laws of motion or Coulomb's law, while an intermediate course may cover more advanced topics such as rotational dynamics or Maxwell's equations. An advanced course in mechanics or E&M may focus on advanced topics such as Lagrangian mechanics or electromagnetic waves.

In conclusion, the main difference between intro, intermediate, and advanced physics courses lies in the level of complexity, depth, and mathematical rigor of the material covered. I believe that all levels of physics courses are important for building a strong foundation in the subject and preparing students for more advanced studies and research in the field.
