Welcome to scubageek.com,

At first we thought that an FAQ for scuba physics would be a good idea, and still do, but this isn't it. Although we're interested in frequently asked questions, we're more interested in questions that are NOT frequently asked, but probably should be. Most of the following articles have something to do with being in, on, or near water (e.g. underwater photography). But some have nothing to do with anything --- we just find them interesting. We invite your feedback, especially if you find any errors. Suggestions for additional topics are certainly welcome.
