Let me tell you about number Four.
Why do I think number 4 is significant?
Firstly, it’s nicely symmetrical. 2+2 and 2×2 and 2^2. Human beings like symmetry. Symmetrical objects are usually considered beautiful and symmetrical features attractive.
Now let’s have a look at how many things there are four of:
| spring | summer | autumn | winter |
Four cardinal directions
| north | south | east | west |
| air | water | earth | fire |
Four states of matter
| solid | liquid | gas | plasma |
Four arithmetic operators
| addition | subtraction | multiplication | division |
Four card suits
| hearts | spades | diamonds | clubs |
And corresponding tarot versions
| cups | swords | pentacles | wands |
Four basic tastes
| bitter | sour | salty | sweet |
Google always uses the same four colours in their logo – red, blue, yellow and green
Four Renaissance artists (or Ninja turtles if you wish)
| Leonardo | Michelangelo | Donatello | Raphael |
Examples from pop culture include Fantastic Four, the four hobbits from Lord of the Rings, four members of Beatles, four women on Sex and the City and four Hogwarts houses.
Examples from sports are the four tennis grand slams and the big four sports in America.
Also, every four years we get an extra day. The leap year, such as this year for example, is dividable by four.
Every four years, on a leap year, we get Olympic Games.
And every four years, also in the same year, a US Presidential election takes place. Better not talk about the current one… anyway, I only realised about two weeks ago that not only was I born in the leap year, my brother was too and so were my two nephews by marriage, whom I love very much.
So that’s it.
And here are four red tealights.
Bonus: the main male character in the Divergent series, Tobias Eaton, is nicknamed Four, because he only has four fears (whereas average is between ten and fifteen). Played by Theo James in the movies.
