Special Relativity

The theory of special relativity discusses how space and time are related to objects traveling along a straight line at a constant speed. Simply stated, as an object reaches the speed of light, its mass becomes infinite and it is unable to move faster than light. This interstellar speed limit has been the topic of much debate in astronomy, and also in science fiction when people consider how to fly over large distances.

Think about the color purple. I’m sure you are imagining a variety of shades of the color of royalty from a deep violet to a subtle lavender and everything in between. But while it seems to be a fairly straightforward concept, describing a color is a much more daunting task. First, we need to understand what color is and how people perceive color. To further confound matters, color vision from one person to another is not set in stone; the variety and combination of the cells in the back of your eyes will determine the colors you see, and the way you’ve experienced the world will teach you how to describe them to others. What started out as a concept that most children learn before they set foot in a schoolroom has quickly morphed into an immensely complex set of issues. To help address some of the complexity of sight and color perception, we will approach it from a cellular level to understand how light can be transduced into a nervous signal.
