HAPPY BIRTHDAY TO GREATEST INDIAN MATHEMATICIAN  SRINIVASA RAMANUJAN
The Indian mathematician Srinivasa Ramanujan Aiyangar (18871920) is best known for his work on hyper geometric series and continued fractions.
Srinivasa Ramanujan, born into a poor Brahmin family at Erode on Dec. 22, 1887, attended school in nearby Kumbakonam. By the time he was 13, he could solve unaided every problem in Loney's Trigonometry ,and at 14 he obtained the theorems for the sine and the cosine that had been anticipated by L. Euler.
Ramanujan became so absorbed in mathematics that when he entered the local government college in 1904 with a meritscholarship, he neglected his other subjects and lost the scholarship. Ramanujan married in 1909, and while working as a clerk he continued his mathematical investigations.
In January 1913 Ramanujan sent some of his work to G. H. Hardy, Cayley lecturer in mathematics at

Dear All
Just do the following multiplication :
13837 x Your Age x 73 = ? ? ?
You get very interesting resut, let me know.
You get the same result if you multiply 10001 * your age * 101
How is that?
INTERSTING NUMBER 37
NUMBER 37 IS AN INTERESTING NUMBER:
111/(1+1+1)=37
222/(2+2+2)=37
333/(3+3+3)=37
444/(4+4+4)=37
555/5+5+5=37
666/(6+6+6)=37
777/(7+7+7)=37

Setting Goals after Board Results
Setting Goals after Board Results
There are certain basic fundas that you need to know while setting your goals :
A) Write down all your goals separately. Writing is described as the act of inscribing characters or shapes on a surface to convey thoughts and ideas. Have you ever wondered why this symbolic, mechanical act is considered so important in the goalachievement process?
It is important because putting pen to paper gives body to our thoughts. It transfers nonverbal cues into tangible, concrete expressions. The writing becomes your signed testimonial. You can look at it, physically from a distance and it will remind you of what you promised yourself a year ago.
This act of using your eye in coordination with your hand, while holding a pen, will make a firm impression on your mind, so while you are reading or rereading a particular phrase, a sentence or a book section, this impression consolidates and slips deeper into our subconscious.
B) Define goals in terms of specific activities and specific processes. Without specifics, the whole exercise is futile and meaningless. So split your goals in terms of specific actions and prioritise those actions.
C) Prioritise and reprioritise your goals. This will help you make the maximum use of your time resource, so that nothing important gets left out.
D) Identify your obstacles. These could be internal, as well as external. Decide what additional knowledge you need to gather before you can set out to achieve your goals.
E) Define your goals and start working backwards from those goals. Affirmative commands are excellent for time management. Keep repeating to yourself, “I am always punctual”, “I am wellorganised”, “I use my time productively.” Repeat these commands in your spare time. Act or pretend as if you have already begun to follow these commands.
In short, fake it until you make it.
To solve a problem or to reach a goal, you...don't need to know all the
answers in advance. But you must have a clear idea of the problem or
the goal you want to reach.

DIFFERENT KINDS OF NUMBERS NUMBERS
Deficient number number whose proper divisors add up to less than itself. For example, 16 is a deficient number as sum of its proper divisors {1, 2, 4, 8} = 15.
Abundant number number whose proper divisors add up to more than the number itself. For example, 18 is a abundant number as 1+2 +3 +6 +9 = 21. Can you find the smallest abundant number?
Happy number number for which the sum of the squares of the digits eventually equals 1.For example, 203 is happy because 2² +0² +3² = 13; 1² +3² = 10; 1² +0² = 1
Can you think of another happy number? An unhappy number?

DIFFERENT KINDS OF NUMBERS NUMBERS
Do you know any perfect human being! May be NO... But, in mathematics there are the numbers which are perfect. Let us consider the following definition:
Perfect number number whose divisors (except itself) add up to itself. For example,. 28 is a perfect number. Its proper divisors are {1, 2, 4, 7, 14} and 1 +2 +4 +7 +14 = 28.
Well, Can you find the smallest perfect number?
All perfect numbers less than 500.
Is 360 a perfect number?
