### HAPPY BIRTHDAY TO GREAT INDIAN MATHEMATICIAN - RAMANUJAN

Dear Reader,

Srinivasa Ramanujan (22 December 1887 – 26 April 1920) was an Indian mathematician, who made extraordinary contributions to mathematical analysis, number theory, infinite series, and continued fractions. Ramanujan independently compiled nearly 3900 results (mostly identities and equations). His work continues to inspire mathematicians even today!

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 merit scholarship, 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 1914 Ramanujan went to Cambridge. The university experience gave him considerable sophistication, but intuition still played a more important role than argument. In Hardy's opinion, if Ramanujan's gift had been recognized early, he could have become one of the greatest mathematicians of all time. His patience, memory, power of calculation, and intuition made him the greatest formalist of his day.

In 1918 Ramanujan was elected a fellow of the Royal Society and a Fellow of Trinity College, Cambridge.

However, the story goes that, Ramanujan’s health deteriorated greatly while he was in England, and he eventually had to travel back to India in 1919. He died a year later, when he was only 33 years of age, although his work will be remembered for a long time. He dealt with Riemann series, the elliptic integrals, hyper geometric series, and functional equations of the zeta function. Hardy liked to rank mathematicians on a scale of 1 to 100, and he gave himself 25, Littlewood 30, David Hilbert 80, and Ramanujan 100, which shows just how great Ramanujan was.
### PRIZE WINNERS - SIXTH INTRA SCHOOL MATHEMATICS OLYMPIAD

### 5 Reasons Why Math Matters

Dear Reader,

Math
is important. It really is.

Despite
how you felt about algebra class or geometry class or even basic addition and
subtraction, math is a life skill that applies to everyone, not just
accountants and engineers. It is the language of many fields, some of which may
surprise you. But math matters, in more ways than one. And while numbers and
equations are a necessary evil to some and pure enjoyment to others, we need
math to live.

Below
are five reasons why math is worth knowing. Starting with…

Building
Stuff: Balancing a cheque-book? Dividing rent among four roommates? Determining
your share of the electric bill? How about taxes and student loans? Paying
bills is the worst, no doubt about it. But you need to know some math in order
to stay on top of your finances, balance your budget, and avoid all those
overdrafts.

**Cooking:**Surprised? Baking cupcakes and roasting a chicken requires math skills. You need to measure the ingredients in terms of teaspoon, tablespoon, ounces, grams, kilograms, etc. And what if you what to cut a recipe in half? This is serious business. Unless you’re a pro at eyeballing the “this much salt” and “that much flour,” you need math in the kitchen.

**Travel:**Planning to jump the pond for a backpacking adventure? If so, better prepare yourself for currency confusion, especially if your currency converter is not a physical device. Knowledge of currency conversion is essential when traveling to a foreign country. Your iPhone may not be able to save you, but your math skills sure can.

**Building Stuff:**There will come a time when you need to assemble a desk, a shelving unit, or perhaps a crib. And you’ll thank your math teacher for helping you become the hero that you are once that desk sits proudly constructed by the window. Putting stuff together requires math aptitude in order to avoid a safety hazard.

**Career Readiness:**Are you thinking of becoming a nurse? How about a marketing manager or a lawyer? Nurses use math to calculate medication dosages, marketing managers use math to determine profit margin and pricing strategies, and lawyers use math to determine settlements and statistical evidence. Even sports agents and high school English teachers use math on a regular basis.

Think
about it. Math really is everywhere. From the kitchen to the courtroom,
numbers, graphs, and measurements are all around us. Knowing how to calculate a
tip at a restaurant or your fantasy football score is important business!
Mortgage payments, caloric intake, and retail discounts are a big part of our
everyday lives. And we can’t always rely on our phones to do the work for us
when it comes to math. Your brain is a much better, and more reliable tool.
