- Physics involves the creative synthesis of multiple ideas.
- Upper division vs. lower division.
- Physics problems may not be well-defined math problems.
- There may be no obvious coordinates or independent variables.
- A physical object rarely comes with a parameterization.
- The unknowns don't have names.
- Getting to a well-defined math problem is part of the problem.
- If you can't add units, it wouldn't make a good physics problem.
- Physics problems don't fit templates.
- Template problems not very useful.
- A few key ideas are more easily remembered later.
- Physics involves the interplay of multiple representations.
