Physics Problems to Challenge Understanding  

Textbooks abound with problems intended to develop one's mastery of physics. Too many are "plug-and-chug" without much opportunity to form deeper insights into physics. This is a collection of problems that are designed to require insight and correct use of basic physics concepts, but do not require mathematical drudgery.

Unsolved problems in physics 

This is a list of some of the major unsolved problems in physics. Some of these problems are theoretical, meaning that existing theories seem incapable of explaining a certain observed phenomenon or experimental result. The others are experimental, meaning that there is a difficulty in creating an experiment to test a proposed theory or investigate a phenomenon in greater detail.
