What poetry has to do with math

We stand to gain much from developing an understanding of ancient India, its deep and diverse ideas.

Over the past year, I have heard my friend, mathematician Manjul Bhargava, give several public lectures on the deep connections between poetry, Sanskrit and mathematics. Like many other mathematicians before him who have written or spoken on this topic, Manjul gave an array of examples that demonstrate the tremendous depth and contributions made by ancient Indian (for the purposes of exposition, stretching perhaps from present day Afghanistan to Burma) philosophers and poets to mathematics, often before their counterparts in Western societies did the same. Manjul’s quintessential example is from roughly 11th century India, when Gopala and Hemachandra discovered a delightful connection between the number of syllables in Sanskrit poetry and mathematics. The answer, it turns out, is what we now call the Fibonacci series (also appears in the number of petals in certain flowers in nature), which was eventually rediscovered by Leonardo of Pisa, better known as Fibonacci, about 50-80 years later.

That there should be an inherent connection between the number of syllables in Sanskrit poetry, a product of human thought, and the number of petals in flowers in nature must startle any reasonable person. Another extraordinary example that Manjul highlights is the discovery of the binomial structure hidden in Sanskrit poetry, as discovered by the ancient Indian poet Pingala, roughly in 200 BC. This was about 1,800 years prior to the French mathematician Pascal’s Traité du triangle arithmétique, which we today learn as Pascal’s triangle. Other examples include the use of techniques that resemble modern error-correcting codes, synchronisation, and formal language definition in Sanskrit poetry and prose. These are all modern inventions (or reinventions, in some cases) that impact almost every aspect of our lives, from computer languages to wireless communications.

It would, of course, be foolhardy to claim the ancients invented or knew of computer languages or wireless communications. That would be like claiming Copernicus built space ships to fly to the moon. Rather, what these examples do highlight is that a long time ago, in or near the region we live in today, there existed a thriving civilisation that produced extraordinary intellectual thought and ideas which continue to have fundamental connections with the way we live today. We appear to have lost knowledge of this ancient past through the vicissitudes and vagaries of time. And with it, a significant source of pride and the ability to influence modern Indian identity. Few people of my generation appear to be aware of these facts.

Part of our ongoing ignorance of the past appears to be structural. Case in point: At my high school in Bangalore, as part of the ICSE syllabus, we read Hamlet, Merchant of Venice, works by Wordsworth, Tennyson, James Joyce, Dickens, etc. We even read Walt Whitman wax eloquent about the end of the American Civil War and Abe Lincoln’s death in “O Captain! my Captain! our fearful trip is done”. Never mind the fact that none of us in class knew what a civil war was at the time, or that America had one, or how or why Lincoln died. We read the tremendously uplifting lines from Tennyson’s “Ulysses”: “To strive, to seek, to find, and not to yield”, all while lacking the context of ancient Greece or even knowing how to say “Ithaca” (we learnt it as EYE-THA-KA). We had little or no context for these strange ideas, words, phrases, stories, heroes and worlds.

And yet, we read these poems, short stories, novels, and wrote essays about them to pass our school exams. This was an enjoyable experience and I would do it again. However, such an educational experience and exposure was severely stunted in its diversity of thought and ideas. What strikes me as odd is that we students never read any classics that originated in this part of the world — that is, ancient India — despite having a cultural advantage of perhaps being able to understand the context better. We knew of no texts, poems, plays, great prose, science, mathematics, civics, political life or philosophy from 2,000-plus years ago from ancient India. My friends and I, stereotypes of the urban educated populace, remained entirely unaware of the intellectual contributions of this past. The most we seemed to know were a couple of random dates and trinkets of information on the Indus Valley civilisation, Ashoka and Chandragupta Maurya, all of which seemed almost perfunctory and without any depth in the manner we read them in school.

As students, we were well versed with Plato, Aristotle, Pythagoras, Copernicus, Newton, Leibniz, Pascal, Galois, Euler, etc, and their tremendous contributions to mankind. And yet, most of us had never read about Aryabhatta, Brahmagupta, Pingala, Kalidasa, Hemachandra, Madhava, the Nyaya or Mimimsa Sutras, or the Therigatha.

But why bother with any of this? After all, we were never part of these accomplishments and they were so long ago, by a people so far removed from today’s reality, that attempting to create any link to the past is surely irrelevant. But I would argue this discovery of the past is no less relevant than what we already study and acknowledge in the earlier cited examples in our schools and colleges. Besides, these sources of knowledge from ancient India are products of creative human thought and hold genuine value for the world, irrespective of where they come from, or geographic affinities. For example, any child on this planet will find mathematics far more amenable when learning parts of it through poetry, as opposed to the dry, dull methods espoused by most mathematics pedagogy today.

While national identity is a complex phenomenon, perhaps in some proportion it relates to the intellectual contributions made by societies to help advance knowledge and improve the human condition. Newton is a hero to many like me, who read in wonder about how he unravelled the basic laws of the universe. Great literature and philosophy from Western societies have helped us reflect on the human condition. Such examples from the Western world have magnified our respect for societies that could harbour, enable and encourage such curiosity. In the same vein, we stand to gain much from developing an understanding of ancient India, its deep and diverse ideas, which are no less extraordinary than those we have come to marvel in Western civilisations. I am not suggesting we lose respect for contributions made by other societies or civilisations, or that everything of note was discovered in this part of the world. Rather, we ourselves have much to gain when we dispassionately discover, examine and acknowledge the intellectual history of ancient India. We may be surprised to find it was perhaps a more open, tolerant and diverse society than even the one we have lived in since Independence. If you need more convincing or inspiration, look up Manjul’s talk on YouTube. Or try reading the Therigatha.

Girl loses way, walkers fly her to Coimbatore for admission

CHENNAI/COIMBATORE, August 10, 2015

Swathi and her mother Thangaponnu at Anna University in Chennai on Saturday.

Instead of TNAU, Coimbatore, the girl and her mother reached Anna University in Chennai by mistake.

For a group of walkers in Anna University, Saturday morning was no less than a page out of a movie script.

Around 6.30 a.m., they saw a woman and a young girl asking people for directions. Curious, some of them approached the duo to offer help.

R. Swathi, who had scored 1,017 marks in her Plus Two, came with her mother Thangaponnu, a shepherd from their hometown of Musiri in Tiruchi. “They were asked to come to Anna Arangam, Tamil Nadu Agriculture University, Coimbatore, but they reached Anna University by mistake,” said M. Saravanan, a former student of College of Engineering, Guindy and a member of a walking group called Twalkers.

Counselling was to start at 8.30 a.m. in Coimbatore. Both mother and daughter had lost hope. One of the walkers brought them breakfast, another went to book and print out the flight tickets, while another was speaking to TNAU staff in Coimbatore. Tickets were confirmed and Twalkers’ members decided to share the cost of Rs. 10,500. Some of the walkers, who are teaching at Anna University, spoke to TNAU registrar C.R. Ananda Kumar, explained the problem and asked for extra time.

“We took off at 10.05 a.m., landed at 11.28 a.m. and in the next hour we had the admission letter on our hands,” Ms. Swathi said. She will now pursue B.Tech. Biotechnology at the Coimbatore campus. “It looks like a miracle now,” she says. The Twalkers did not stop there. They called up Thangaponnu to confirm if they had secured the admission. “It was very kind of them to do so. They came around like an angel when we had lost hope,” Swathi said.

After getting the seat and back in their hometown in Musiri, the mother-daughter are now planning to visit Chennai again. “We want to return the money they spent to buy our flight tickets. How else can we say thank them,” Ms. Thangaponnu said.

Revealing the secret behind Gayatri mantra

Most probably, the first god that humans recognised and worshipped was the sun.

LIFE |  Commonsense Karma  |  07-08-2015

Hari Ravikumar  @hari_ravikumar

Which is the oldest religion in the world? Nobody knows. Ask the foremost historian or the greatest saint but they will not have an answer. We know so little about the earliest humans who inhabited our planet. But we can take an educated guess about the first god. Keep aside for a moment the view that god created the universe and just consider how humans visualise god. Most probably, the first god that humans recognised and worshipped was the sun.

Also read: How I became a sun worshipper

There are many reasons for this. The sun is the most magnificent object in nature. The sun gives us light and energy. Without the sun, there would be no life on earth. Our existence depends on the sun. Also, the sun was considered the master of time. The sun creates days and nights, thus making us grow old. So the ancient people treated the sun as a god. Most of the ancient cultures that we still know about have a reference to the sun god. (George Carlin uses the same idea in one of his brilliant sketches on religion.)



George Carlin --- Religion is Bulshit


From the limited information available about our past, we know that Hinduism is the oldest religion (or "way of life", as some people prefer to call it) and in this tradition, the Rigveda Samhita is the oldest work. The Rigveda Samhita is divided into ten sections (known as maṇḍalas) and each section has several poems (called sūktas). Each poem is further made up of verses (known as ṛks). Perhaps the most famous verse from the Rigveda is the savitā gāyatrī mantra.

The Gayatri mantra is a 6,000-year-old verse recited by millions of Hindus every day all over the world. This mantra – Rigveda Samhita 3.62.10 – was composed by sage Vishwamitra. He composed most of the poems in the third section of the Rigveda.

This verse is called the Gayatri mantra possibly because it is composed in the poetic meter called Gayatri. A verse written in this poetic meter should have three lines and each line must have eight syllables. It is interesting to note that the etymology of the word Gayatri is gāyantaṃ trāyate iti gāyatrī, "Gayatri is that which protects the person who recites it."

Therefore, although there are thousands of verses composed in the Gayatri metre, when we say Gayatri mantra, it specifically denotes this verse:

tat saviturvareṇyam |

bhargo devasya dhīmahi |

dhiyo yo naḥ pracodayāt ||

In Sanskrit, every word has several meanings. So it’s important for us to understand the context in which a certain word is used. Let us take a look at what each word in this mantra means:

tat = that

savituḥ = the sun; literalley "one who permits", "one who stimulates", "one who vivifies"

vareṇyam = best, excellent, worthy of the highest respect

bhargaḥ = light, lustre, radiance

devasya = of god, of the lord, of the deity

dhīmahi = (we) meditate, contemplate

dhiyaḥ = intellect, wisdom, mind, consciousness

yaḥ = the one who, he who

naḥ = to us, for us

pracodayāt = (one who) inspires, motivates, stimulates, empowers

(An astute observer will find that the first line has only seven syllables instead of eight: tat-sa-vi-tu-rva-re-ṇyam; therefore while recitation, we add the syllable om in the beginning or we say tat-sa-vi-tu-rva-re-ṇi-yam).

Let us try to arrange this in the form of a sentence. One who (yaḥ) stimulates (pracodayāt) our (naḥ) mind (dhiyaḥ) – we meditate (dhīmahi) on that (tat) excellent (vareṇyaṃ) radiance (bhargaḥ) of the lord (devasya), the sun (savituḥ).

A simple English translation would give us:

We meditate on

the wonderful radiance of the sun god,

who stimulates our mind.

The same Gayatri mantra also appears in the Yajurveda but with an additional line in the beginning:

oṃ bhūrbhuvassuvaḥ |

om = the single-syllable word that represents brahman, the Supreme Being

bhūḥ = earth

bhuvaḥ = atmosphere

suvaḥ = sky, heaven

With this line, we bring our awareness to the three spheres of existence, thus connecting with something bigger than our tiny selves.

In the Hindu tradition, we believe that there is only one Supreme Being (brahman) but there are several gods. These gods may be realized in any form.

The forces of nature – wind, lightning, thunder, fire – are deified. The animate and inanimate beings – animals, plants, rivers, mountains – are deified. The celestial objects – sun, moon, planets, stars – are deified. We may also see god in a sculpture, a painting, or even in a song.

Among all these various possibilities, the sun is the most magnificent. Of course, an astrophysicist might tell us that the sun in our solar system is a veritable pygmy in front of some of the other stars in the universe. Even so, the sun remains the most brilliant object we can see with our naked eyes. Not only do we see it but we also feel its presence. It removes darkness and brings light. It removes the cold and brings warmth. The radiance of the Supreme represents Knowledge (which removes the darkness of ignorance) and Vitality (which removes the coldness of lethargy).

So the Gayatri mantra is a prayer to the Supreme, in the form of the sun, which stimulates our mind and empowers us. Just like the sun wakes us up every morning, we pray that the Supreme light wakes up our intellect. It is indeed a prayer for internal strength.

In the 1990s cartoon series Captain Planet, there is a beautiful symbolism for this – whenever Captain Planet is on the verge of defeat, he draws energy from the sun. He gets revitalized. He’s ready to face his enemies – those trying to pollute the earth. The Gayatri mantra does something similar, but within.

(In preparing this article, I have drawn heavily from the lectures of HH Sri Rangapriya Swami; my discussions with Shatavadhani Dr R Ganesh; Dr Koti Sreekrishna’s article on the Gayatri mantra; and Vol 17 of the 36-volume Rigveda Samhita translation in Kannada brought out by the Maharaja of Mysore, Sri Jayachamarajendra Wadiyar during 1948-62.)

Benevolence Vs Malevolent: Stories of opposite ending

Uttar Pradesh man helps wife marry lover, sees her off with gifts

Besides throwing out a lavish lunch, Phoolchand and his family members also gave gifts to the newly wed at the time of `Vidai.

It could well be a perfect script for a Bollywood romance block buster but for Phoolchand it was sort of a heart break when he performed the marriage and `vidai' of his wife with smiles on his face.

Chanda, a resident of Bikapur village of Faizabad district, had an affair with a youth Suraj of the same village. However, bowing to the wishes of her parents, she married Phoolchand in 2012. Phoolchand, a native of the adjacent village Palipoorab, happily took his bribe to his house.

However, as fate could have it, he had to leave for Jalandhar immediately to earn money. Though the husband wife talked to each other frequently on phone, Chanda's and Suraj's love further blossomed as Suraj used to visit his relative in the Palipoorad village. His relative's house is close to Chanda's house and to ensure a meeting, Chanda used to visit his house on one pretext or the other.

Meanwhile, Phoolchand returned back on August 4 only to get a shocker. Chanda, not only returned the jewelery, clothes and other items that Phoolchand gave her at the time of marriage, but also told her the truth.

"I was happy that she relied on me and told me the truth. I got angry and sad for some time but decided to take out a solution", Phoolchand said.

After discussing the matter with his father, Phoolchand reached Chanda's village along with his father and confronted the village panchayat. "I kept forward my suggestion that Chanda and sooraj whould be allowed to marry and I have no objections", Phoolchand said.

After a long discussion, the Panchayat agreed to Phoolchand's offer and Sooraj and his family were also summoned. Sooraj and his family members agreed with in no time and the marriage was performed at the village's shiv mandir on Thursday.

 "This shows the mental level and strength of our youths these days and we salute Phoolchand for this brave step. It is better to accept the truth and act accordingly than to linger on with a forced relationship throughout life", Ravindra Yadav, the village head of Bikapur said.

Besides throwing out a lavish lunch, Phoolchand and his family members also gave gifts to the newly wed at the time of `Vidai' with blessings of a happy married life.

In Modi's Varanasi, lover's head tonsured

The head of a lover-pair were tonsured and they were paraded all over in village Koirajpur under Bargawan police station in Varanasi on Sunday night.

Much against the belief that the west UP is brutal towards lovers, this time a similar incident took place in east UP. The head of a lover-pair were tonsured and they were paraded all over in village Koirajpur under Bargawan police station in Varanasi on Sunday night. When the father of the youth, who has run away with a girl, rushed to the police station for help, the cops allegedly said: "Go and make a complaint with Prime Minister Narendra Modi."

Incidentally, Varanasi is Parliamentary constituency of Modi.

The villagers were angry because the lovers eloped from the village last month when they were prevented from marriage. However, they had returned back four days ago.

"They tonsured our head and thrashed us while forcing us to parade in the village. This happened against the wish of our parents. Although our parents were against our marriage, they had accepted us two days ago", said Lalji Kumar, 19, the youth.

"When we went police station, the policemen rebuked us and asked to make a complaint with Modi, because he is our MP", said Shyamji Singh, a relative of the youth.

Govt. job portal lists manual scavenging as ‘career option’

Mohit M. Rao

August 4, 2015

Cleaning of sewers, descending into manholes, removing night-soil (human excreta) using a broom find 
a place in the National Career Services portal.

The job profile of a “Safai Karamchari” and a “scavenger” is listed as being “mildly hazardous or dangerous” – putting them in the same category as “astrologer”

What was conceived by the Narendra Modi-led NDA government as bringing employers and job seekers on a single platform, seems to now promote and allow the hiring of the prohibited act of manual scavenging at the click of a button.

Cleaning of sewers, descending into manholes, removing night-soil (human excreta) using a broom find a place in the National Career Services portal that was launched recently as a part of Skill India.

For instance, under the ‘unorganised sector’ panel of the website, a “Sweeper, Sewer” is “expected to” clean sewage systems by “using various cleaning instruments,” including bamboo or iron rod, and collecting debris and refuse in a bucket using a spade and handing this bucket to “helper outside manhole.”

Similarly, the “Sweeper, Wet” description lists a “key competency” of removing “night soil using spade and broom.”

On its launch by Prime Minister Narendra Modi on July 20, the portal was to link two crore job seekers with nearly nine lakh establishments. Mr. Modi had then said: “…it is essential for Indian society to develop a consciousness towards ‘dignity of labour’.”

However, advocates Clifton D’ Rozario and Maitreyi Krishnan — who had taken the issue of manual scavenging to the Karnataka High Court — say: “These dehumanising [definitions] are the very practice due to which the manual scavenging community has been stigmatised, ostracised and discriminated. [It] is now being proudly promoted as a ‘career option’.”

Furthermore, employing persons under these definitions have been made punishable with imprisonment under the Prohibition of Employment as Manual Scavengers and their Rehabilitation Act, 2013, the advocates say.

‘Inhuman practice’

They also point to the Supreme Court order (dated March 27, 2014) in the Safai Karamchari Andolan vs. Union of India case, where the court observes that handling human excrements with bare hands, brooms or metal scrappers or in baskets is an “inhuman practice,” while in November 2008, the Chennai High Court had directed that the cleaning of sewage could only be through mobile mechanical pumps or other devices.

Acknowledging that the description did indeed become promotion of manual scavenging, M. Shivanna, Chairperson, National Safai Karamchari Commission, said, “This is definitely wrong, and amounts to promoting such activities. Though we have been insisting that Sucking and Jetting Machines should be used, the website implies that descending into manholes is also a part of the job.”

The commission will issue a notice seeking clarification on Wednesday, he told The Hindu.

In same league as astrologers

Incredibly, the job profile of a “Safai Karamchari” and a “scavenger” is listed as being “mildly hazardous or dangerous” — putting them in the same category as “astrologer” and “palmist” that come under unorganised sector careers.

While the risks for “Safai Karamchari” include “lung, respiratory, neurological diseases, infection, biological diseases, suffocation, fatigue,” for an astrologer or palmist or money lender, the dangers include “heart diseases, depression and anxiety, fatigue, stress.”

The website similarly contains unfortunate, now antiquated phrases for describing jobs. “Domestic Servant” is described as “performing the general house-hold duties and attending to the personal comforts of master or employer” — terms that show “underlying feudalism,” say advocates Clifton D’ Rozario and Maitreyi Krishnan.
