Science of Swimming – While our lectures discussed scuba-diving, I became very curious in what actually happens as I swim and the physics behind my stroke mechanics and efficiency. This article provides good descriptions and visuals for how the body interacts with the forces presented by the water.

The Effects of Underwater Pressure on the Body – First, I didn’t even think about how the pressure changes affect a fish caught from the water. I appreciate how this video provides a visualization of the physics processes and anatomical effects of someone diving.

Would a Straw Work in Space? – This question came to mind during this unit’s lectures. According to my thought process, I was misled to believe that the straw wouldn’t work, but the article nicely sums up how “sucking,” that is, the pushing of atmospheric air, works in the space shuttle because of the pressurized air inside. This site provides an explanation that supports what we’ve learned.

Aircraft Pressurization Beginner’s Guide – This article provided a nice summary of all of the physics that go into the pressure while on board an airplane. Whenever I fly, I always think of how “weird” things feel with my ears, head, and breathing. Obviously, those feelings all have scientific explanations, so it was good to read and explore more.
