Some important uses of the number nine

 

Some important uses of the number nine.

Part of a series. Previous posts have been for the numbers two through eight, and, God willing, there will be two more posts, for ten and twelve. The uses of nine in this poster seem straightforward enough without my commentary.

Thanks for looking!

Some important uses of the number four

 

Poster showing uses of the number four, and using four colors, four typefaces, four corners and four sides.

There are four freedoms in the First Amendment to the US Constitution; four fundamental forces, or interactions, holding the universe, you and me, and atoms and molecules together; four sides and four corners in many of the basic building blocks of buildings; four limbs in vertebrate animals, and, conventionally, four directions. There are more uses of four, or groups of four, that I have not thought of, no doubt.

Thanks for looking! I expect to post more of these posters in the future.

Some important uses of the number three

 

Some important uses of the number three.

Perhaps the most important use of the number three is in naming the Trinity. Do I understand the Trinity? Certainly not. In the so-called "love chapter," Paul said that there were three things which would endure beyond time, namely faith, hope and love. In addition, the US has three branches of government; there are three germ layers in embryonic development in vertebrates; there are three primary colors, and normal people have three types of cone cells in their eyes, which receive light of these three kinds; there are three commonly discussed states of matter (there is actually a fourth such state); monocot reproductive structures have three-fold symmetry (see here) -- monocots, including wheat, rice, maize/corn, and other plants, are very important to humans.

Some important uses of the number two

 

A poster showing some of the important uses of the number two. Some of these are biblical, including the statement by Jesus that no one can serve two masters, and also the statement by Jesus that if two of his followers agreed on a request, it would be granted. Then there are some things we take for granted, such as that we, and many animals, have two sides, right and left; the two sexes; that the things we see on our devices, and in books, are (mostly) two-dimensional; and that computer information is stored, transferred and used as binary information, 1s and 0s.

Thanks for looking! God willing, I'll be posting more such posters, using other numerals. For the post on the number four, see here.
