I always get up on the wrong side of the bed. When the sun is located near one of the horizons, an observer looking at the sky directly overhead will view partially polarized light. Liquid crystal displays create patterns by controlling the a. wavelength of light. We can read maps. The colors on maps have meaning.
Maps follow the same conventions as vision.
Maps are drawn to scale. Both our vision and maps only represent reality. Space and time are absolutes. Energy is conserved only in elastic collisions. Speed of light in a vacuum is same for all observers.
