Physics Stack Exchange is a question and answer site for active researchers, academics and students of physics. It's 100% free.

I am looking for a site that publishing riddles and problems such as Project Euler publishes problems in computer science. Is there any similar site that is hardcore in the area of physics?

This site has some good problems set, but it seems like there isn't a community and sharing of solutions/ideas like in Project Euler.

Before answering, please see our policy on resource recommendation questions. Please write substantial answers that detail the style, content, and prerequisites of the book, paper or other resource. Explain the nature of the resource so that readers can decide which one is best suited for them rather than relying on the opinions of others. Answers containing only a reference to a book or paper will be removed!

Could consider an Area51 for this. There's a puzzing beta. I'd support a dedicated physics problems/solutions SE site. –  DanielSank Sep 18 at 1:18

I think the harvard physics problems of the week are pretty nice:

Those problems seem to have ended back in 2004. Are they still posting new ones somewhere? –  Marty Green Feb 11 '12 at 17:06
@MartyGreen I don't know if they are still posting new ones, would be great if the author would start posting new problems again. Perhaps someone should ask him to do so... –  student Feb 11 '12 at 23:04

One nice source of physics problems is books which catalog questions from graduate school qualifying exams. For example:

Another source of tricky problems is:

The contest is sadly extinct, but problems (and solutions!) from the contests that took place 1995 - 2004 are available online.

In the same vein, Yung-Kuo Lim compiles a large repertoire of graduate qualifying exam questions. A quick search will find you this PDF on Thermodynamics and Statistical Mechanics questions. –  Tom Neiser Oct 13 '14 at 16:36

Just like the example student offered, this one isn't active any more, but makes a nice compilation:

You might also try this site for a "physics problem of the week" kind of thing:, although the problems seem like they've been running for just a couple of months.
