Last and First Quarter Moons
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.
Digital technology really did get started in Africa as this Ted Talk asserts.
these facts are not generally disputed. Moreover there are still lessons to be learned by looking at STEM through the lens of African history. The Art of Memory by Frances Yates are helpful in this regard as is Africa Counts: Number and Pattern in African Cultures by Claudia Zaslavsky.
When you are texting or using Twitter, Jesse Russell is one of many who deserve a tip of the hat. While he did not invent either texting or Twitter or even 2G communications as many mistakenly believe, Jesse was
a pioneer in the field of cellular and wireless communications. In 1988, Russell led the first team from Bell Laboratories to introduce digital cellular technology in the United States.
The spread of texting would not have been possible without Jesse’s invention and Twitter’s 140 character model was based on texting. Non-obvious interconnections between inventions happen all the time. The Connections TV Series and book
demonstrated how various discoveries, scientific achievements, and historical world events were built from one another successively in an interconnected way to bring about particular aspects of modern technology.
Biologically we have many ancestors. Sometimes it’s clear where a particular trait came from but often it’s not. Still we can tip our hat.
