Narcissistic number

Interesting name, isn’t it?

How can a number be narcissistic?

☻When it focuses too much on itself☺.

It will represent itself even after some manipulation of its digits.

“A number is said to be narcissistic if the sum of its own digits each raised to the power of the number of digits is equal to itself”

For example:

153=13 + 53 + 33 = 153.

These numbers are also called as Armstrong numbers or plus perfect numbers.

The following video has some details about this…

Blaise Pascal

Yesterday was the birth anniversary of the famous French Mathematician Blaise Pascal(18-6-1623 to 19 -8-1662). He is a child prodigy with no formal education.

He invented the mechanical calculator at a very young age.

He is the first person who proposed the idea of public transportation in 1662 in France. He introduced the seven horse drawn carriage routes for the public. They are called as the “Five-Penny Coaches,” or “Carosses à Cinq Sous”.

In science, his focus was mainly on fluid dynamics.

The following video explains his other achievements

Krishnamurthi number

A Krishnamurthi number is a number whose sum of the factorial of the digits is equal to the number itself.

KRISHNAMURTHI NUMBER

Palindrome day!

A palindrome number is a number that remains the same when its digits are reversed .

Today’s date is one such example.

12-3-21, even if it is reversed, the answer will be the same .

Doubly even order Magic Square

We know to construct the magic square of odd order, constructing the even order magic square is little tricky, we solve this by dividing the even numbers into doubly even and singly even. Let us first see about the doubly-even here, because singly-even comprises odd and doubly-even magic square constructing methods.

The following video will brief you about building the doubly-even magic squares.

MAGIC SQUARE

Magic square – It is a square matrix, i.e., it has equal number of rows and columns. The sum of the numbers in any rows, columns and diagonals is always the same.

Creating magic squares are very easy if we follow certain rules, They are clearly explained with an example in the following video.

‘2021’ is the year of partner in prime.

Happy New year!!!

THALES

Thales used the principles of geometry to solve real life problems. Therefore, he is considered as the ‘First true mathematician’.

PYTHAGORAS

Pythagoras is best known in mathematics for the Pythagoras theorem .
He was a philosopher who related numbers to the things in real life. He linked numbers with gender,colors, music etc.,
Pythagoras believed the earth was round and orbits are circular, This belief led to the Copernican theory of the universe.

NO NOBEL FOR MATH

This is probably because Alfred Nobel who created the awards did not consider mathematics to be as practical as physics chemistry or medicine.
