"Physics is hard."

But practicing physics is rewarding.

Interested in getting involved in learning more physics? Here are some cute and smart physics puzzles:

1. Quantum: The Magazine of Math and Science: Between 1990 and 2001, some American physicists collaborated with the Soviet Adacemy of Sciences and put together a magazine with challenging and stimulating physics and math puzzles, along with ageless nerd jokes.
   
2. Quanta Magazine: Not to be confused with the former, Quanta promises "illuminating basic science and math research" and is an online publication lauched by the Simons Foundation.
   
3. Fairy Tales: Musings on everyday physics which lead to intricate and elegant physics insights. I was at one of Dr. Khmelnitskii's talks in Cambridge once. He managed to go from ducklings following mommy ducky to Rayleigh-Taylor instabiltiy and then the trailing wave angle being 19 degrees... Mind-blowing.

Useful information to study physics and prepare for high-school physics competition:

1. I have been involved in The US Physics Team since 2009. The program invites high school students from around the nation to compete in two rounds of selection exams every year. The top 20 will make up the US Physics Team, and 5 of them will represent the US to compete in the Internation Physics Olympiad (IPhO). Both websites have archives of previous exam papers.
   
2. If you live in the Boston Area, you may be interested in checking out the Boston Physics Circle led by Harvard professor Ariel Amir.
   
3. IPhO study guide created by Jaan Kalda, long-time leader of the Estonian Physics Olympiad Team.
   This site is by Kevin Zhou, two-time IPhO gold medalist, and current graduate student in Physics.
