HAPPY BIRTHDAY TO GREATEST INDIAN MATHEMATICIAN -- SRINIVASA RAMANUJAN

Image
The Indian mathematician Srinivasa Ramanujan Aiyangar (1887-1920) 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 Cambridge . Hardy noticed that Ramanujan had rediscovered, and gone far beyond, some of the latest conclusions of Western mathematicians. In...

What is the best way to study mathematics

Dear All Once open a time a lady wanted to hire a cook for her restaurant. She interviewed many candidates and finally she selected the one who impressed her in the interview. Lady was very impressed with his knowledge of cooking. He was like a cooking encyclopedia. On his first day of the job, lady thought of taking his trial. She asked him to cook “Kadai Chicken“. She started eagerly waiting for the food. Food was served and she had her first bite. It was pathetic in taste. She could not swallow even a single bite of it. The lady was shocked and asked the man “It is so horrible in taste. Are you sure you can cook food?” He replied, “Madam, sorry for the food. Actually I have never done cooking before. I just had taken lessons on cooking from experts and during my training classes, I saw the instructor cooking. Also, I have read and learned all the recipes of making excellent food.” Moral of the story is, there is a difference in knowing how to do things and actually being able to do ...

INTERSTING NUMBER 37

NUMBER 37 IS AN INTERESTING NUMBER: SEE THE PATTERN: 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)=37 888/(8+8+8)=37 999/(9+9+9)=37 hope you like it... do you have other number patterns to share... do write in comment section.

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 goal-achievement process? It is important because putting pen to paper gives body to our thoughts. It transfers non-verbal 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 co-ordination with your hand, while holding a pen, will make a firm impression on your mind, so while you are reading or re-reading a particular phrase, a sentence or a book section, this impression consolidates and slips deeper into our subconscious. B) Define go...

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

Dear All 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?

Math Joke

A math major studied hard in the university library all evening. On his way home, he felt very hungry so he stopped at a nearby pizza place and ordered a large pizza. When it was ready, the pizza guy asked him if he wanted it cut into six or eight pieces. The Math major replied, “Cut it into six—I don’t think I could eat eight pieces.”
