### Why Study Math? Math is everywhere! Don’t believe me? Read on for some examples of math in nature.

Bees, masters of geometry, use hexagons to build their honeycombs. The Fibonacci sequence, a famous sequence of numbers in mathematics, is found throughout nature: in pinecones, seashells, trees, flowers, and leaves.

The number pi can also be observed all around us. Pi is a cool number with many unique properties. Pi is approximately 3.14, but in reality it is greater than 3.14, with an infinite string of numbers after the decimal point. Because pi is, in reality, an infinitely long number, it is expressed as the Greek letter pi (π). It cannot be expressed as a fraction; numbers that cannot be expressed as fractions are said to be irrational. Pi is also transcendental, which means that it is non-algebraic; this means that pi cannot be the solution of single-variable polynomial equation whose coefficients are all integers. (By definition, all transcendental numbers are also irrational.)

The number pi can be observed in the shapes of rivers. The ratio of a river’s length to the distance from the source to its mouth is called the “meandering ratio.” The average meandering ratio of rivers approaches the number pi. It makes sense that the average meandering ratio of rivers approaches pi, because rivers tend to bend into loops, which are circular in nature. The ratio of a circle’s circumference to its diameter is also equal to pi.

Now that you know more about pi and about how math governs nature, don’t you feel that you have a greater command over the mathematical laws of the universe? It can be empowering to learn about mathematical principles because it can help make sense of a world that, oftentimes, does not make much sense.

1. Math can make you more popular. Before you start to disagree with me, think about how great it is to go to dinner with a friend who can quickly divide a check in their mind to determine how much each person needs to pay to split the bill. Your knowledge of fractions can also help you divide a pizza among a few people. While math is popularly the realm of nerds, your ability to avoid awkward confusion and silence as you and your friends try to divide a pizza or a dinner bill is truly a valuable skill. Be known as the cool (yes, I said cool) person that knows how to do mental math quickly!
