 Everyday has its own importance.

2nd November 2024 = 307th day of year 2024

307 is the  number whose square is a Palindrome number

3072=94249

The next such number is 836 whose square is a palindrome number.

836 x 836 = 698896

Birthday 

1. George Boole (2 Nov 1815 - 8 Dec 1864) :  A self taught English mathematician , who was the son of a shoemaker. He is best known as the author of 'The Laws of Thought' which contains Boolean Algebra, a branch of mathematics widely used in computer algorithm.

On 2nd November 2015 , Google released a Doodle on Boole to mark his 200 th Birthday.

Interesting things to know George Boole

1. His wife name was Mary Everest Boole ( her uncle was George Everest, whose name is given to the highest peak of the world- Mount Everest)

2. In late November 1864, Boole walked, in heavy rain, from his home at Lichfield Cottage in Ballintemple to the university, a distance of three miles, and lectured wearing his wet clothes. He soon became ill, developing pneumonia. As his wife believed that remedies should resemble their cause, she wrapped him in wet blankets – the wet having brought on his illness. Boole's condition worsened and on 8 December 1864, he left for heavenly abode.

Importance of Number 2

                                        Important Characteristics of Number 2

Read More on Numbers in My Book “The Power of Mathematical Number “by Rajesh Kumar Thakur

1.    Two is the only number x such that the sum of the reciprocals of the powers of x equal to itself.              1 + ½ + ¼ + ¹/₈ + --- = 2

2.  Square root of 2, i.e √2 is the first known irrational number discovered by Pythagoras. Though Baudhayana also gave the approximate value of square root of 2

           समस्य द्विकरणी । प्रमाणं तृतीयेन वर्धयेत, तच्चतुर्थेनात्म चतुस्त्रिंशोनेन सविशेषतः । 

3.      Two (2) is the only even prime number.

4.      There are no integers x, y, z for which xⁿ + yⁿ = zⁿ  is valid if n > 2. This is known as Fermat’s last Theorem. This theorem was proposed by Piere de Fermat in the year 1670 and it remained a mystery for the mathematicians for over 350 years until it was proved in year 1995 by Andrew Wiles. In case n = 2, the equation turns out to be a Pythagoras Theorem.

5.      N² ± N is divisible by 2 where N is a natural number.

6.     H, I, O and X have two lines of symmetry.                                                                                                                                                                                                                                                    

 7.      The common symmetry found in nature is bilateral. A single axis has two sides one goes in positive direction and another goes in negative direction. Our bodies are bilaterally symmetrical and we naturally distinguish the thing in two ways , e.g Right and Left, Up and Down etc.

8.      A number is divisible by 2 if it ends with 0, 2, 4, 6 and 8.                                 

         Example: 248, 98634, 666, 900 are divisible by 2 but 41, 333, 79 are not divisible by 2.

9.      2 can be partitioned in two ways.

10.  A binary code is written to base 2 and has just 2 digits 0 and 1. In binary system the odd number ends with 1 and even number ends with 0. This system was first used by Leibniz in 1679 though it is referred to in a Chinese book which supposedly dates from about 3000BC. Leibniz associated 0 with nothingness and 1 with odd.  In binary number system 14 is written as 1110 and is represented as (14)_{10 =} (1110)_2.

11.  For any polyhedron, the Euler’s formula is V – E + F = 2, where V , E and F represent Vertices, Edges and Faces respectively.
12.  Atomic number of Helium is 2.

13.  Two has a unique property such that 2 + 2 = 2 x 2.
14.  Chess, Squash and Sumo wrestling are all games played by two competitors.

15.  A figure having length and breadth but no depth is called a 2- dimensional object.

16. There are 20 digits in the expansion of 2⁶⁴ but surprisingly the base 2 is disappeared.         

       2⁶⁴ = 1,84,46,74,40,73,70,95,51,616

17.All known Perfect Numbers are Even, i.e. divisible by 2

18. Goldbach conjecture says that every even number greater than 2 is the sum of two prime numbers. Example : 8 = 3 + 5

19.  In many culture 2 symbolizes balance, harmony, and partnership, as seen in the concept of yin and yang in Chinese philosophy.

20. It is the first Ramanujan Prime. In 1919, Ramanujan published a new proof of Bertrand's postulates which was first proved by Chebyshev.  At the end of the two-page published paper, Ramanujan derived a generalized result, and that is:

${\displaystyle \pi (x)-\pi \left(\frac{x}{2}\right)\ge 1,2,3,4,5,\dots \text{ for all }x\ge 2,11,17,29,41,\dots \text{ respectively}}$  where  is the prime counting function that is equal to the number of primes less than or equal to x.
