The Golden Ratio – The Key to Amazing Design Experiences


The Golden Ratio, also referred to as the Golden Section, Golden Mean, or Divine Proportion, is the ratio of a line segment cut into two pieces of distinct lengths such that the ratio of the longer segment to the shorter segment is equal to the whole segment to that of the longer segment. It is denoted by the symbol Phi [ø].

For example, a line segment AB divided into two distinct lengths AC & CB; here AC is the longer part and CB is the shorter one, then as per the definition of the Golden Ratio stated above, mathematical representation will be as:

Suppose the longer part AC is ø and the shorter part CB is 1, then putting the value of AC, CB and AB in the above equation as shown below:


The equation ø2 – ø – 1 = 0 is a Quadratic Equation [ax2 + bx + c = 0]

Now use the Quadratic Formula 

in the above Quadratic Equation by using the given values a = 1, b = -1 and c = -1 as shown below:


The positive solution can be written as shown below:

Solving this equation will give the value of ø = 1.61803398874989484820……., which can be written as 1.61803398875.

The Golden Ratio plays a key role in design, this mathematical approach helps to get closer to creating amazing design experiences all the time.

So, use this amazing concept for better designs.

The Number 1.6: Base of Fibonacci Sequence and the Golden Ratio

This post is about the number 1.6 that forms the base of the mathematical concepts Fibonacci sequence and the Golden ratio. For better understanding of this amazing number 1.6, it is important to know about Fibonacci sequence and the Golden ratio. Golden Ratio The  Golden ratio is the ratio of a line segment cut into two pieces of distinct lengths such that the ratio of the longer segment to the shorter segment is equal to the whole segment to that of the longer segment. It is denoted by the symbol Phi [ø]. Suppose there is a line segment AB, and C is any point that divides the line segment AB into two pieces of distinct lengths such that AC is greater than CB. Then, as per the definition, [ø] = AC/CB = AB/AC. The value of the Golden ratio [ø] is 1.6 1803398875 . As you can see, the value of the Golden ratio starts with the number 1.6. For more information on the Golden ratio, see https://theamazingconcepts.blogspot.com/2021/07/the-golden-ratio-key-to-amazing-design....

Harshad Number or Niven Number

The concept of Harshad number was given by D. R. Kaprekar, one of the great mathematicians from the country India. Harshad number or Niven number is any positive integer b that is divisible by its sum of digits (SOD). The term Niven number was coined by Ivan Morton Niven, a Canadian-American mathematician, who specializes in number theory. As per the definition: Harshad number b = number / sum of digits Below are some examples: Number 12 Sum of digits = 1 + 2 => 3 Here, number 12 is divisible by its sum of digits 3, and the resultant is 4. Number 18 Sum of digits = 1 + 8 => 9 Here, number 18 is divisible by its sum of digits 9, and the resultant is 2. Number 72 Sum of digits = 7 + 2 => 9 Here, number 72 is divisible by its sum of digits 9, and the resultant is 8. Number 110 Sum of digits = 1 + 1 + 0 => 2 Here, number 110 is divisible by its sum of digits 2, and the resultant is 55. Number 135 Sum of digits = 1 + 3 + 5 => 9 Here, number...

Kaprekar Number

D. R. Kaprekar (Dattatreya Ramchandra Kaprekar) introduced an amazing concept Kaprekar number in number theory. Kaprekar number is a natural number whose square when divided into two equal or non-equal parts; left and right, then the sum of both parts must be equal to the original number. None of the parts should have the value zero. The Procedure Step 1: Consider a natural number n. Step 2: Square the number n 2 . Step 3: Divide the value after square into two equal or non-equal parts: left x or x-1 digits and right y digits. Step 4: Add both left and right parts: (x + y) or (x-1 + y). Step 5: If the resultant z is equal to the original number n, then number n is a Kaprekar number, else not. For Example Number n: 9 Square the number n 2 : 9 2 => 81. Divide the value after square into two equal or non-equal parts: 8 and 1. Add both left and right parts: 8 + 1=> 9. Here the resultant 9 is equal to the original number n. Hence, 9 is a Kaprekar number. ...
