Okay kiddies, it's science day. There are some basic laws of science you need to know. They can be very important.

First, there is no such thing as cold. There is only absence of heat. When I was outdoors a few days ago, I came inside and told my financial controller, "There is a major lack of heat in that north wind today."

Heat moves to cold. Don’t believe it? Just light a common kitchen match and stick it to your finger. The reason you feel pain is that you’re about 98.6 degrees and the match is over 1000 degrees. And, if you put a piece of ice onto your hand, it feels cold because your body heat is moving to the area with less heat. That brings up, does heat rise?  It can but it can also fall or go sideways. When you open an oven door, the heat moves sideways to get out. Heated air does rise. But it may not want to.

There is no such thing as dark, only an absence of light. Have you ever opened a sealed container that you know has no light? Did the room get darker? The light in the room went to the container too.

Hang on, there is a point to all this somewhere.

Wet moves to dry. That’s why you use a dry bath towel. It would do no good to take a towel into the shower with you and expect to use it to dry off.

Wind and water take the path of least resistance. Think about it. If you get behind a building when the wind is blowing, there is no wind. It goes around the building. Water creates rivers and canyons because it is following the path of least resistance.

All of these try to equalize to the opposite. Water seeks its on level only because the pressure is unequal until it does. Wind is created until atmospheric pressure is the same.

Humans take the path of least resistance not because of the laws of natural science, but because they might have to think or take an action. That’s the point.

Don’t you feel better knowing this? I know I do.
