I guess I have become addicted to E2.
Physics, at least for me, is a bore. I sit at my desk and daydream throught the whole class.
Today, we were studying the motion of waves, along with wave length, frequency, and other wave characteristics. The teacher then explained how to determine the wave length. This was simply the distance between peak to peak, trough to trough, or node to node. At this point, physics was cast aside as I began thinking about E2.
