The Light Side . . . . . . Humorous anecdotes relating to photobiology, with new items appearing on an irregular schedule. Check back frequently. However, in at least one case those laws may not be quite so immutable.
Cats appear to have their own set of physical laws.
Therefore, in its continuing effort to provide the latest information of relevance to the science of photobiology, the Light Side proudly presents the Laws of Feline Physics. First Law of Energy Conservation Cats know that energy can neither be created nor destroyed and will, therefore, use as little energy as possible. Second Law of Energy Conservation Cats also know that energy can only be stored by a lot of napping. Cat Inertia A cat at rest will tend to remain at rest, unless acted upon by some outside force - such as the opening of cat food, or a nearby scurrying mouse. A cat will move in a straight line, unless there is a really good reason to change direction.
