In Chapter X of my "So You Want To Be A Physicist" essay, I mentioned the process of selecting your research adviser/supervisor for your graduate work. This is possibly the most important person in your academic life and selecting someone compatible is an extremely important aspect of your education.
In last week's Science, there's a wonderful essay on the same issue that focuses on your interaction with your PhD supervisor. It deals with communicating with your supervisor no matter what style he/she adopts. This is very important especially if your supervisor is a well-known scientist that is in very high demand. So this is definitely a useful essay if you are about or just starting your graduate program.
