Isaacphysics "Extraordinary Problems"

We here present collections of problems that are rather more wide-reaching than individual questions on isaacphysics.org.

We present them as pdfs here since they may require repeated and close reading, best done perhaps from a print-out that you can also annotate. The on-line versions are at https://isaacphysics.org/extraordinary_problems.
