I described the basics to reading a scientific paper in Understanding a Scientific Paper Part 1, but there are still more tricks to understanding a scientific paper.

After reading one paper, I spent weeks wondering what was the "background, ultraviolet radiation" that interfered with photometers during the day. Then, my professor pointed out that it was sunlight. Learning to understand scientific papers requires you to think in a new way, and I have found some tips helpful for making this process easier.
