Mathematics Movement
Srinivas Ramanujan, the keen Indian mathematician, occupies a unique pose inwards history of mathematics. Despite of all challenges, he rose to move i of the most outstanding creative mathematicians of modern times. His operate continues to engage the attending of peak researchers inwards mathematics all over the world. He was born on 22nd Dec 1887, this yr 2012 is S. Ramanujan’s 125th nativity anniversary. So every bit a tribute to our keen Indian Mathematician, Prime Minister Manmohan Singh declares 2012 every bit “National Year of Mathematics”.
In this consider a three days workshop for students together with teachers volition move held at SDPS, Pitampura from 26 July to 28 July 2012. I am glad to move a business office of Mathematics Movement.
Objectives of Programme:
1. To select radical changes inwards the mental attitude of people, the agency they intend nearly Mathematics together with Mathematics education.
2. To withdraw fearfulness of mathematics from mutual man.
3. To amend pedagogical effectiveness inwards teaching of Mathematics.
4. To inculcate reasoning every bit habit together with the might to perceive a province of affairs from a multidimensional perspective.
5. To educate the feel of appreciating whatever Mathematical concept from its application betoken of thought along amongst its pure mathematical individual together with abstractness.
6. To select dorsum the glory of Indian contribution past times familiarizing the people amongst Vedic mathematics together with past times highlighting the link betwixt Vedic together with modern Mathematics.
7. To render 24×7 back upwards to teachers, students together with parents through online together with offline platforms.
8. To usage online platform to teachers together with students to create, collaborate, share, acquire together with to displace together to select progressive changes inwards mathematics education.
9. To educate Mathematics resources pump for all.

• One tin meliorate analyze, comprehend, synthesize, holler back in addition to generate novel ideas.
• Mind Mapping is an of import technique that improves the trend yous stimulate got notes, in addition to supports in addition to enhances your creative occupation solving.
• By using Mind Maps, yous tin apace lay in addition to empathize the construction of a dependent area in addition to the trend that pieces of data lucifer together, equally good equally recording the raw facts contained inwards normal notes.
• You tin utilization it for learning, brainstorming, memorizing, visual thinking in addition to occupation solving
• It is likewise useful for summarizing information, consolidating data from unlike interrogation sources, thinking through complex problems in addition to presenting data inwards a format that shows the overall construction of your subject.

Song On Srinivasa Ramanujan
SECTION 1
In 1887, inwards the town of Kumbakonam
H5N1 infant boy, Ramanujan, was born.
His mom knew inwards her heart,
From the stars she could chart,
This was no ordinary mind.
The man child grew as well as played,
While the woman parent sat as well as prayed,
Namagiri give us guidance as well as strength.
With each passing year,
It grew increasingly clear
This was no ordinary mind.
The teachers at school,
Didn’t know what to do
With this immature man, as well as thus many years ahead.
One gave him a math mass past times Carr –
5000 equations to explore.
For improve or worse, a approving may live a curse.
He lost involvement inwards everything simply math.
SECTION 2
His notebooks filled with formulas
that no i had conceived;
simply his college courses suffered,
as well as thus he was asked to leave.
His woman parent arranged him a marriage
To eleven-year onetime Janaki.
Now he had to beg for a job
To feed his novel family.
Boarded a develop outflow for Madras
Leaving his family, his novel wife, far behind.
Showed his notebook to Inida’s brightest
Hoping to find, at last, to a greater extent than or less other brilliant mind.
Someone who’d understand… his math…The math was equally good far higher upward them
And as well as thus his spirits sank.
They had no means to determine
Was he a genius or a crank?
And as well as thus he sent out letters
To those who mightiness understand
Twas Hardy who finally recognized
The brilliance of this man.
He’d flora person to understand… his math…
Boarded a ship, outflow for Cambridge
Leaving his country, his people, as well as thus far behind.
Thus began math’s nearly famous collaboration,
Between these 2 extraordinary minds.
SECTION 3
Hardy welcomed him to Cambridge.
Helping his talent to get got wing.
But with his skills at that topographic point was a weakness:
He had never learned how to bear witness things.
Ramanujan’s conjectures were ingenious
Despite all the gaps inwards his knowledge.
With Hardy supplying the details as well as proofs,
The results were astounding.
His insights on continued fractions,
Primes, as well as diverging series
Dazzled the best mathematicians,
Alluding to build novel theories.
And with each novel newspaper he published,
He was i stride closer to fame,
Fulfilling his clandestine desire,
That the the world would yell upward his name.
Srinivasa Ramanujan (4x)
Cut off from his domicile as well as his loved ones,
He felt an astute isolation.
The honour he had earned from his colleagues
At times seemed a minor consolation.And with England weather condition as well as thus dreary,
His trunk was wasting away.
While hospitalized for consumption,
The majestic social club honored his name.
Srinivasa Ramanujan (8x)
SECTION 4
In 1919, his wellness was as well as thus poor,
It was finally fourth dimension to build the journeying home.
To pass his concluding days inwards the town of Kumbakonam,
With the bride he’d hardly known.
The lastly twelvemonth of his life,
While nursed past times his wife,
He recorded 600 novel ideas.
To this real day,
His notebooks remain
H5N1 origin of equations to explore.
And i thing’s for sure,
Though his life was cutting short,
The the world volition yell upward his name.
