When it comes to **mathematics**, everything seems to be tricky. Maths had been a nightmare and had haunted a moderate number of students. But mathematics has fun and lesser-known side, let’s call him “maths.” We had playfully kept maths in the shoes of a frantic lover searching for his ‘X’ for ‘find X’ in questions. Let us see some These are Cool Things About Maths.

Well, maths can be personified and could alter into almost anything. The whole world works on numbers – time, years, dates, phone numbers, country codes, street numbers, etc. Our computers are more close to maths than to us since everything in computers works on 0, 1 bits. Even the latest emerging technology –artificial intelligence, machine learning – is primarily just branches of maths like calculus, algebra, linear algebra, statistics, probability theory, optimization.

This mighty field of numbers is so widespread that even nature works on mathematics. That’s fishy right; how could nature work on mathematics? But it’s true; nature indeed creates a lot of things after plotting with maths.

**6 Cool Things About Maths You Have to Know**

Let’s take a deeper look at the cooler and lesser-known side of maths.

**Nature Creates Beautiful Patters Following the Fibonacci Sequence**

The seed pattern in sunflower follows the Fibonacci series. The Fibonacci sequence is as follows – 1,1,2,3,5,8,13,21 …it is succeeding by adding the two preceding numbers. This forms the Fibonacci spirals. The seed heads of sunflower, pine cones, pineapples, and romanesco cauliflower have a spiral pattern curving out left and right. If we count these spirals, the total number of spirals will be a Fibonacci number in the series.

Many other plants express the Fibonacci sequence through their growth points, even the petals of flowers are in Fibonacci. E.g., lilies, wild roses, etc. Even the human body follows a Fibonacci pattern as body proportions and measurements are in terms of the golden ratio. These are Cool Things About Maths.

**In a Hive, a Drone Family Tree Follows Fibonacci Series**

In a colony of honeybees, the drone family tree is in Fibonacci series as drones hatch from unfertilized eggs and have only one parent, whereas queens hatch from two parents – a queen and drone.

So the drone family tree has one parent, two grandparents, three great-grandparents and five great-great-grandparents, and so forth. These are Cool Things About Maths.

**Multiplying 11*11 Gives a Palindromic Number **

Multiplying two numbers of the same number of digits, of repeating ones gives a palindromic number (where numbers are in the natural order and repeated in the reverse order in the same natural order).

This applies to even bigger numbers from 1111 * 1111 = 1234321 to even 1111111111* 111111111 = 12345678987654321. These are very Cool Things About Maths.

**Imaginary Numbers are Used in Real Life by Engineers to Define Electrical Currents**

An Imaginary number is a complex number having a real number which is multiplied along with an imaginary unit ‘i’ and also the square of an imaginary unit ‘i’ is -1 i.e., i² = -1. Imaginary numbers are denoted by ‘j’ in electronics as ‘i’ is already defined for current. They are applied to alternating current (AC) as alternating current changes between positive and negative values in a sine wave. For combining alternating currents on the waves, we use imaginary numbers.

Also, imaginary numbers are in-use for signal processing in the field of radar technology, biomedical technology), cellular technology, wireless and wired-technology as the measurement is mainly of a sine or cosine wave which is in transmission through spaces or mediums. These are Cool Things About Maths.

**Obelus and Lemniscate– What are those?**

Obelus is the name for the division sign. It is a Greek word where the symbol consisting of a horizontal line with a dot above and below it.

Lemniscate is the name for the infinite sign. It is a Latin word. In geometry, curves shaped like the ‘8’ are lemniscate. There are three types of lemniscates curves depending upon the three quadratic plane curves– lemniscate of Booth, lemniscate of Bernoulli and lemniscates of Gerono, all named after the scientist who proposed it. These are Cool Things About Maths.

**The World’s Most Beautiful Number is 1.61803399**

The world’s most beautiful number is 1. 61803399. People call it as the golden ratio, golden proportion, divine number, divine section, and the golden mean. The **Golden Ratio (two quantities are in the golden ratio if their ratio is the same as the ratio of their sum to the larger of the two quantities). **Also, the addition of two Fibonacci numbers is very close to the golden ratio. These are Cool Things About Maths.

So now, as to why it is called the world’s most beautiful number? People use the golden ratio everywhere for centuries. You can notice them in paintings, architecture, designs, etc. Maintaining the golden proportion has always resulted in a visually appealing and beautiful creation. The golden ratio is also in nature. You can notice them in the arrangement of branches on trees and the arrangements of veins on the leaf and even the proportions of the human face. The human face follows the pi and golden ratio.

Some examples of golden ratio noticed around the world are CN tower in Toronto, Taj Mahal in India, Notre Dame in Paris.

So, maths is indeed magical. We can’t deny how diverse the field of maths is. Also now we come to know that actually, maths is everywhere. We just aren’t aware of it, that’s it. Hope you enjoyed the Cool Things About Maths.
