Height

If you don’t read the web comic “xkcd” you should. The author does a fantastic job of illustrating some scientific concepts that are difficult to understand any other way.

One of these is how tall or how high up some things actually are. And if you keep going up, you get into space. How far away are those things in space? Well, xkcd has a great chart showing you. It’s on a log scale, so every two inches or so that you go up on the chart is actually DOUBLE the height of the previous two inches.

Enjoy.
