Living in a metropolitan city like Chennai, METRO means many things! Metro water tankers plying to cover nook and corner to provide drinking water, pedestrians and vehiclers(?!) trying to cross with least regard for safety and getting into collision, blaming metro tankers for all the ills something unfortunate!
This week’s Sunday story (1800th post) in ENVIUS THOUGHTS  deals with the pride of the city METRO RAIL and my recent ride just for its sake from Thirumangalam to Airport and back was indeed a nice and pleasant experience -for me who has not even seen since it started three years ago!


There are two corridors as of now and the details:

Corridor Length
Washermenpet to Airport 23.1 kms
Chennai Central to St.Thomas Mount 22.0 kms
Total 45.1 kms.

The details of the two corridors are given below:

Washermenpet–Broadway (Prakasam Road)–Chennai Central Station–Rippon Building–along Cooum River–Government Estate–Tarapore Towers–Spencers–Gemini–Anna Salai–Saidapet–Guindy–Chennai Airport

Chennai Central–along EVR Periyar Salai–Vepery–Kilpauk Medical College–Aminjikarai–Shenoy Nagar–Annanagar East-Anna Nagar 2nd avenue–Tirumangalam–Koyambedu-CMBT–along Inner Ring Road–Vadapalani–Ashok Nagar–SIDCO–Alandur–St. Thomas Mount.

The portions of Corridor-1 with a length of 14.3 kms. from Washermanpet to Saidapet, and Corridor-2 with a length of 9.7 kms. from Chennai Central to Anna Nagar 2nd Avenue will be underground and the remainder elevated.

My jolly ride with my two boys, daughters in law and grandson was just for a little more than a couple of hours last week. We enjoyed it thoroughly as there was no rush worth mentioning.

My boys who have seen several Metro rails in the country and abroad opined that Chennai Metro Rail can be rated as the best! Frequency, maintenance of the coaches and the stations, over all cleanliness every aspect was spic and span!

Here are some of the snaps we had:


This way I enjoyed my maiden METRO VOYAGE on 28th December.
We end this Sunday Story with this and we shall meet tomorrow as usual and till then BYE!
May GOD be with YOU!

National Mathematics Day

It is said that Mathematics is the mother of all Sciences!! True without Mathematics no arts or Science subject can develop and flourish. Hence it is in the fitness of things that National Mathematics day is observed and that is on December 22nd today. Envius Thoughts brings out a Sunday Story on this day for the information of all our esteemed viewers which is bound to provide some good inputs. Let us enjoy the post on this salubrious Sunday! This is on the 1786th Day of the Blog and 1720th post. Let us carry on.
National Mathematics Day is celebrated on 22 December every year to mark the birth anniversary of legendary Indian mathematician, Srinivasa Ramanujan and his contributions in the field of mathematics. Let us read more about National Mathematics Day, its history, significance and how is it observed.

As we know that since ancient times various scholars had made significant contributions to Mathematics including Aryabhata, Brahmagupta, Mahavira, Bhaskara II, Srinivasa Ramanujan and others. At the very young age, Srinivasa Ramanujan showed the signs of an unfolding genius and his contributions regarding fractions, infinite series, number theory, mathematical analysis and so on set an example in mathematics.

On 22 December 2012, the former Prime Minister of India, Dr. Manmohan Singh, paid tribute to Srinivasa Ramanujan at a function organised on the occasion of the 125th birth anniversary of the great mathematician Srinivasa Iyengar Ramanujan in Chennai. 22 December was declared as National Mathematics Day. Thus, on 22 December 2012, National Mathematics Day was celebrated across the country for the first time.
National Mathematics Day 2019: Significance

The main objective behind the celebration is to raise awareness among people about the importance of Mathematics for the development of humanity. We can’t ignore that several initiatives are taken to motivate, enthuse and inculcate a positive attitude towards learning Mathematics among the younger generation of the country. On this day, training is also provided to the Mathematics teachers and students through camps and highlights the development, production, and dissemination of teaching-learning materials for Mathematics and research in related areas.

How is National Mathematics Day celebrated?
National Mathematics Day is celebrated in various schools, colleges, universities, and educational institutions in India. Even the International Society UNESCO (United Nations Educational, Scientific and Cultural Organisation) and India had agreed to work together to spread Mathematics learning and understanding. Along with this, various steps were taken to educate the students in mathematics and spread knowledge to the students and learners all over the world.
NASI (The National Academy of Science India) is the oldest science academy situated in Allahabad. To celebrate National Mathematics Day, NASI conducts a workshop in applications of Mathematics and Ramanujan. The workshop is attended by popular lecturers and experts in the field of Mathematics from across the nation. Speakers at the country and world level discuss Srinivasa Ramanujan’s contribution to mathematics.

The two days workshop on the topic ‘History of Indian Maths before 16th Century’ is also organised during 30-31 December, 2019 at the NASI headquarters at Prayagraj.

The theme of the workshop will be important talks/presentations followed by a thorough discussion on the contributions of Indian Mathematicians from the Vedic period to the medieval period which have been accepted by the whole mathematical world without controversy. Discussion in the workshop will cover the following topics:

– Indian Contribution during Vedic Period
– Indian Contribution during Classical period
– Indian Contribution during the medieval period.

All the states of India celebrate National Mathematics Day in different ways. Various competitions and mathematical quizzes are conducted at schools, colleges, and universities. Mathematics talent and students from all over India participate in these programs and workshops.
About Srinivasa Ramanujan and his contributions in Mathematics
Srinivasa Ramanujan was born on 22 December, 1887, Erode, India and died on 26 April, 1920 at Kumbakonam. His family was of the Brahmin caste and lived in poverty. At the age of 12, he had gained knowledge in Trigonometry and without anyone’s help, he had developed his own theorems and ideas.Just at the age of 15 he obtained a copy of George Shoobridge Carr’s Synopsis of Elementary Results in Pure and Applied Mathematics.

He had spent his childhood days in great difficulty in poverty. He used to borrow books and read books from friends in school. When he was young, he took up the job of clerk to meet the economic needs of the house, and when he gets the time he used to solve mathematics questions and worked on various types of theorems. Once, an Englishman saw those pages,he was impressed and took a personal interest. He sends Srinivasa Ramanujan to the Hardy, the Professor of Oxford University. He then recognized the talent hidden in him and thereafter he got fame worldwide.

His papers were published in the Journal of the Indian Mathematical society in 1911. He had compiled about 3900 results mainly identities and equations that too on his own without anyone’s assistance. Several results out of them are original and novel like the Ramanujan prime, The Ramanujan theta function, partition formulae and mock theta functions. These results further inspired several other research and opened new fields of work. He discovered his own theory of divergent series, worked out the Riemann series, the elliptic integrals, hypergeometric series and the functional equations of the zeta function. Number 1729 is known as the Hardy-Ramanujan number.

National Mathematics Day is observed on 22 December every year to spread awareness about the importance of mathematics and the contributions made by the scholar of mathematics Srinivasa Ramanujan. The government of India decided in 2012 to celebrate National Mathematics Day on 22 December on the birth anniversary of Srinivasa Ramanujan. Since then it was celebrated on 22 December every year.
The post’s aim was to provide some basic facts and we do hope the objective was achieved to some extent. We are sure that you have enjoyed reading this post.
This far is for this week’s Sunday story and tomorrow we shall meet as usual. Till then GOODBYE!

Robert Browning who wrote GRAMMARIAN’S FUNERAL


Robert Browning and his Grammarian’s funeral are indeed great
“On the earth the broken arcs; in the heaven, a perfect round.”
The line I like most as it has given me the vision for life.
” AIM HIGH, ACHIEVE HIGH” I used this thousands of time to motivate all!

The POET says:

That low man seeks a little thing to do,
Sees it and does it.
This high man, with a great thing to pursue,
Dies ere he knows it.

That low man goes on adding one to one,—
His hundred’s soon hit;
This high man, aiming at a million,
Misses an unit.
That has the world here—should he need the next,
Let the world mind him!
This throws himself on God, and unperplexed
Seeking shall find him.

Let us aim at a million- no matter we miss by an unit
A place in heaven is sure for me as my aim was high
‘Aiming high and missing’ better than ‘aiming low and achieving’-joy unbound!
