Part 1 of this series began at the first quarter phase of the Moon on 01-16-2016. Today we’re at the last quarter which is as illustrated above, the visual and geometric opposite of the first quarter. These two positions of the Moon are also the second primary set of binary/polar relationships after the new and full Moon positions. Today, in part because few people farm we’re not as directly connected to the practical value of these polar relations. The full moon is hard to ignore but we’re generally not familiar with waxing, waning or gibbous(when’s the last time you heard someone say that word). Ironically, while science pays less attention, there are many people who are aware of at least the crescent moon phases for religious reasons. Still, our awareness doesn’t change the fact these relationships encode the same valuable knowledge as boolean math and logic gates which power computers. In Part 3, we’ll take an in-depth look at how digital logic drives the relationships which govern how the Moon’s orbit presents the Sun’s light to us.
