NATIONAL MATHS DAY on 22 DEC 2016

Ramanujan's Birthday at my home

Happy Birthday to Srinivasa Ramanujan

Today is the 130^th birth anniversary of great Indian Mathematician Srinivasa Ramanujan and so is National Mathematics Day.

Srinivasa Ramanujan was born on 22 December 1887 in Erode, Tamil Nadu. He is a man known for his work done in the field of mathematics. And that too with no formal training of that subject which others are getting in European countries.  Ramanujan developed his own mathematical research in isolation. Some extraordinary contribution done by him in the field of mathematics are – mathematical analysis, number theory, infinite series, and continued fractions. Along with this, the legend has provided many theorems.

He was enrolled into Telegu School, but found it too tiring and uninteresting to attend school and mostly he use to ran away from there. Later in 1904, he graduated from Town Higher Secondary School. He also received a scholarship to study at Government Arts College in Kumbakonam. During his studies he was so influenced by studying mathematics that he could not focus on any other subject and failed in all of them. This resulted him in losing the scholarship. Later, without any degree, he left the college and continued to pursue independent research in mathematics.

His unconditional love for mathematics was driving him to develop new things for that subject, but to support his livelihood he was working as a clerk in the Accountant-General's office at the Madras Port Trust Office. He kept working on inventing new mathematical theorems and continuously tried contacting the experts from west.   G.H. Hardy, an academician at the University of Cambridge, recognized the brilliant work produced by Ramanujan and invited him to visit and work with him at Cambridge. Here, Ramanujan became a Fellow of the Royal Society and a Fellow of Trinity College, Cambridge.

Some of the known works, produced by this great mind, are - Landau–Ramanujan constant, Mock theta functions, Ramanujan conjecture, Ramanujan prime, Ramanujan theta function, Ramanujan's sum, Rogers–Ramanujan identities and Ramanujan's master theorem.

Ramanujan died on 26th April, 1920, when he was only 32 years of age. In this short life he gave around 3900 results, mostly equations and identities and almost all of them prove to be correct and original.

G. H. 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.

The Indian mathematical genius Srinivasa Ramanujan was born on 22 December 1887. It was in recognition of his contribution to mathematics the Government of India decided to celebrate Ramanujan's birthday as the National Mathematics Day every year and to celebrate 2012 as the National Mathematical Year.

Seventh Intra School Mathematics Olympiad - Solution Key

Dear Readers,

Mathematics, often called as language of nature has become an integral part of everyone’s life. In today's highly competitive world, one has to bear a lot of mental stress and also have to get involved in so many things in order to acquire knowledge. This is where co-scholastic activities play a very significant role. They provide the much needed exposure for a student.

Worth Reading: MESSAGE BY SHIV KHERA TO YOUNG GENERATION

MESSAGE BY SHIV KHERA TO YOUNG GENERATION

1. Take pride in performance

People who take pride in their performance hold themselves accountable to much higher standards than others do.

They always strive to do the right thing, first time every time.

To them, good is not good enough.

2. Get involved

Remember, 'If we are not part of the solution then we are the problem'.

There are people who have a habit of constantly criticising anything and everything no matter where they are.

They only want to criticise without taking any corrective measures.

However, if you don't want to get involved then you have no right to criticise.

Either get involved or shut up.

3. Always put in extra efforts

If you read through the life history of the most successful people, you will find they have all lived by one principle and that is, "I shall always give more than what I get, to my family, my organisation, my customers and my society".

Winners always put in extra effort even when it hurts.

Nobody has become a champion in this world without putting in the extra effort. It is the extra that turns the ordinary into extra ordinary.

This principle applies to any profession; Medicine, Law, Accountancy, Architecture etc.

Would you want to go to an ordinary Surgeon or to an extra ordinary Surgeon?

4. Take a stand

If you look at the life histories of most great leaders, you will find that they were never neutral.

They always took a stand either for something or against something.

They had conviction.

There is a big difference between a preference and a conviction in life.

Preferences are negotiable, convictions are not.

Under pressure, a preference becomes weak whereas a conviction becomes stronger.

5. Be focused

Studies show that less than 5 per cent people have written goals.

This means that they are the only ones who have a very clear destination.

The balance 95 per cent work for them directly or indirectly.

Think about it -- how can you reach a destination that you don't have?

Suppose you go to watch a football game where both teams are enthusiastically charged up ready to play.

Suppose at this point the referee took the goal post away, what is left of the game? Nothing!

They have no goal post, how do you keep the score?

Destination determines direction.

6. Choose your friends carefully

Sometimes you hear that the leader is good, but his advisors are bad.

This statement is not true.

You will find that all over the world, by and large, leaders always choose their own advisors.

Remember we do not get advisors in life of the kind of people we want, we get the kind of people we are.

We don't get friends of the kind of people we want, we get the kind of people we are.

We get attracted to the kind of people who are similar to the kind of people we ourselves are.

Where you will be five years from now shall depend on two things: the books you read and the company you keep.

Today where we are is also the result of the books we read and the company we kept in the last five years.

7. Build high self esteem

Self esteem is defined as the way we feel about ourselves.

You notice that one day we get up in the morning feeling good, the world looks nice, productivity goes up, relationships are a lot better.

The reverse is just as true.

Self esteem is inversely related to egos.

There are two kinds of egos that are destructive.

'The know it all': people with this kind of ego demonstrate arrogance.

They put down and look down upon others.

Think about it, why does a human being put down other human being?

It is sadistic but true, there are some people who feel good when the other person feels bad.

They feel superior when the other person feels inferior which means they don't want to lift themselves up, but they want to pull others down.

The second kind of ego is called the fragile ego, they take anything you say personally and get hurt.

What do both these egos do to team work?

They just destroy it.

8. Build character

Character is something that a person would or would not do even if no one is watching.

It is integrity and authenticity in its true form.

There is a big difference between reputation and character.

Reputation is what other people think about us whereas character is what we know who we are and they can be two totally different things.

Some people are honest because they don't want to get caught telling lies.

They are doing the right things for the wrong reasons.

They are only building a reputation.

Some people are honest because they believe it's the right thing to do.

They are doing the right thing for the right reason. That is character.

9. Live purposefully

What is a purpose?

A lifetime goal is called a purpose.

How do you define your purpose?

Supposing you are aged 100 today and you were to look back at your life, what is it that you want to say, is your accomplishment?

That accomplishment is your purpose.

Have a lofty purpose in life.

Only a lofty purpose has the power to move the spirit.

Shoot for the moon, even if you miss, you will become a part of the stars.

A great philosopher once said, "I would rather fail in doing something great then succeed in doing nothing".

There is glory in such failure too.

10. Start your day on a positive note

Why should we start our day on a positive note every day?

It is because just as our bodies need food every day, our minds need positive thoughts every day.

Starting the day on a positive note sets the tone for the entire day.

Staying positive is like fire; unless we keep adding fuel, it dies out.

Similarly if we don't feed our minds with positive thoughts, everyday, positivity dies out.

Many times you hear that success is tough.

My answer is: Try failing and see if that is easy!

11. Make courtesy a way of life

A courteous person who is not very sharp will go much further in life than a sharp, discourteous person.

Courtesy is made up of little sacrifices in life.

Every courtesy has a moral background.

When people practice courtesy as a strategy, they are crooked; they have ulterior motives.

For people with integrity, courtesy is a way of life.

Pi Approximation Day

Dear Readers,

Do you know what’s special about today,   22 July? 
Well, today is Pi Approximation Day.

Pi Approximation Day celebrates the mathematical constant π (pi). It is observed on July 22, due to π being roughly equal to 22/7.

The fractional approximation of π ,²²⁄₇, resembles the date July 22 in the day/month format, where it is written 22/7. Pi Approximation Day is therefore celebrated on July 22.

In geometry, pi is defined as the ratio of a circle's circumference to its diameter. July 22, often written as 22/7, is an appropriate day to explore pi, since 22 divided by 7 is an approximation of pi.

Pi Approximation Day is celebrated in a number of ways, including contests to memorize pi to the most decimal places, solving math problems involving pi, discovering the history of pi, ruminating on how life would be different without pi and—of course—eating pie.
At my school, a competition 'Math's Wizard' was held today for classes VI - XII. It was a 30 minute one word answer test. Here are the question papers of different classes:

VI CLASS

VII CLASS

VIII CLASS

IX CLASS

X CLASS
