Mr. Blake warned us that today was his favorite day, but (no offense, Mr. Blake) I wasn't too excited because I couldn't be sure that he wasn't super stoked about some new equation or other mathematic hell. As it turned out though, the day was really cool. We learned about how colored lights work, and the day ended up looking something like this:
We relearned the color wheel from first grade art class, but now instead of using it for pigments, we're using it as the color that gets reflected from a surface. For example, the reason my wall is blue (besides an extraordinary amount of paint) is that when a white light is shone on it, there are red, orange, yellow, green, blue, indigo, and violet rays all hitting the wall. Because the wall is blue, it's only going to reflect the blue light into our eyes, so that we see it as blue. All the other colors will be absorbed by the wall, so that all we see is the blue.
