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.

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
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:
whereis the prime counting function that is equal to the number of primes less than or equal to x.
Numbers are very fascinating. Every number is unique
and I have written the properties of number 1 - 100 in my blog highlighting
some of their characteristics.
