Description
Creating a clock-accurate sundial tailored to your location is a simple and cost-effective project. Sam Muller's guide provides a modern approach to this ancient scientific tool.
By observing the shadow of your sundial, you can accurately determine the current time and also witness the effects of the Earth's tilt, rotation, and changing orbital speed. On a moonlit night, notice how the moon's counterclockwise orbit around the Earth results in a small loss of time each hour, explaining why a lunar month is shorter than a solar month.
This book has been written by Sam Muller, a science teacher with a long history of inspiring young minds to explore the wonders of science. With clear instructions and explanations, you can create your own accurate sundial at home.
