Circles.

I was talking to B the other day about circles. They are super cool. They are perfect, and they don’t end. It’s kind of a freak of nature. I think circles are the new “now.” Principles of circles are embedded in basically every aspect of our lives. From the shape, to waves, to– well, just about everything.

Check this cosine wave next to me. It’s explaining that if a point travels all the way around a circle once, the cosine changes in time from its value of 1, to 0, then to -1, then to 0, and back to 1 again. It’s exactly like a spring moving up and down. If you were to put a circle on its side and observe the point move, it’s look like a point in spring moving side to side, or up and down.

The slowest that the point is moving is when it is at its most negative, and its most positive point. The fastest it is moving when it is at zero. Those equations are the wave functions– don’t worry too much about those now. As far as actually using a circle to form a wave, the explanation below helps.The word orthogonal is a synonym for perpendicular, or 90 degrees apart. The reason I’m always amazed by this is that everything we know in this life is understood, measured, analyzed, and manipulated with the help from the circle. What things are those that effect us so much? Everything from sound, to light, to anything electronic, and so on. Below is the electromagnetic wave spectrum. It might interesting to note, that our PDA devices function by microwaves, we see with visible light, radio waves are used for communication, and so on. The measurement represented starts at 100 meters in wavelength and goes to pico meters.

To understand what this means, and analyze it, you’ll need to all about circles. This stuff is all just a little sample of why circles are awesome.
