Well, this was a bad day, kind of like the song. I was sick all day and finally, on the way home, I had to pull over and take care of business. I caused some rubber-necking, I think. Hopefully, no accidents.
In class today we discussed pressure some more--this time fluid pressure. With fluids, the particles individual forces all add up, producing a force in all directions. So, with water for instance, if you are under the surface, you will feel pushed on every square inch of your skin. In the meantime, the inside of your body pushes back out, equalizing the pressure, balancing it out. We talked about inverse variance and direct proportions. Elevation and pressure vary inversely, while depth and pressure vary directly.
More fun on Monday when Dr. Awesome pays a visit. Hopefully, we can capture him on camera.
