Pi Day

March 14 is Pi Day.  Those who have some familiarity with basic arithmetic will know that pi is a mathematical constant - a ratio, in fact - whose value is approximated to 3.14.  So 14/3 (or 3/14, as the Americans write it), today, is pi day.

Interestingly or coincidentally, it is also the birthday of Albert Einstein, arguably the greatest genius who ever lived. 

The New Yorker has published, among many illuminating articles, a very humorous questionnaire on the occasion: Diagnostic Exam: Do You Have Math Anxiety?  A sample question:

What is a hypotenuse? 
(a) A very graceful hypot. 
(b) An overweight chanteuse. 
(c) The  French word for profound boredom.
Mathematics is often assumed to be a scary monster.  Actually it can be sheer fun if we learn to exercise our logical faculty properly.  Most people don't want to think - that's the simple truth.  Mathematics calls for some abstract thinking also which is assumed to be boring or even scary.  Hence many give up maths.  In other words, they give up logical thinking.  And they run after frauds like godmen and miracle workers.  

There's so much irrationality in our world today in spite of all the progress that we are making  with the help of science and technology which are founded on mathematics.  We want the benefits of rational thinking.  We have no shame in accepting the contributions of rational thinkers when it suits us.  But when it comes to our petty notions about many things which are nothing more than superstitions, we cling tenaciously to inanities.  

That's why Pi Day is important.  We have to bring some basic maths into our lives.  Some simple rational thinking.  

A concluding question adapted from The New Yorker:

What do you do when you travel to a foreign country and need to figure out the currency?
(a) I ask, “How much is that in real money?”
(b) I ring up my godman's receptionist.
(c) I demand nationalism and seek to convert my country's currency as the international currency.

  3. Teaching math has become a bone of contention - how do we teach math correctly? Do we make kids memorize tables, or do we teach them to think? Do we follow traditional methods of teaching or do we apply methods that are confusing to parents but ok to kids? Many Indian friends have made their kids learn their tables. While I was wondering what I should do with my son who hasn't yet 'achieved' that fete, my son comes home and tells me the solution to a multiplication sentence and asks me to give him another one. I try him and he solves that. I ask him how he did it and he tells me the logic his teacher has taught. Do I boast that he knows the tables now....:D? Not really. But I am happy he is understanding the method.

    1. A very interesting question from you, Sunaina (as usual, I must add).

      Teaching math requires entirely different strategies according to the level. At the elementary level, it is important to teach the primary tables to the child. Basic addition and multiplication should be part of the child's primary skills. You can't do away with rote learning here.

      The logical skills develop gradually. No child will enjoy learning geometry unless he learns to employ logical skills. When he comes to algebra, abstract thinking and analytical skills also become necessary. The real skill of the teacher lies in developing those skills and it is not a very easy job. But it need not be a Herculean task either.

      I understand that teachers often fail in ensuring that the pupil knows the fundamentals required for the particular concept. For example, before teaching factorisation a teacher should ensure that the pupil knows basic arithmetic of addition and multiplication as well as employing those skills to divide numbers into their possible factors.

      At the higher levels, the challenges are very demanding simply because a lot of fundamental concepts have to be understood by the pupil before getting into the complexities involved.

  4. An interesting post and discussion here:) By the way, I wish many people read this post and ponder over the virtues of logical and critical thinking.

    1. As far as I have understood, people don't want to think. They want others to do that job for them. That's why we have so many religion-related problems these days.

  5. What a great post! I laughed out loud at option c of the hypotenuse question :)

    1. The credit should go to the New Yorker.

      Glad you liked it.

The Adventures of Toto as a comic strip

  'The Adventures of Toto' is an amusing story by Ruskin Bond. It is prescribed as a lesson in CBSE's English course for class 9. Maggie asked her students to do a project on some of the lessons and Femi George's work is what I would like to present here. Femi converted the story into a beautiful comic strip. Her work will speak for itself and let me present it below.  Femi George Student of Carmel Public School, Vazhakulam, Kerala Similar post: The Little Girl

The Art of Subjugation: A Case Study

Two Pulaya women, 1926 [Courtesy Mathrubhumi ] The Pulaya and Paraya communities were the original landowners in Kerala until the Brahmins arrived from the North with their religion and gods. They did not own the land individually; the lands belonged to the tribes. Then in the 8 th – 10 th centuries CE, the Brahmins known as Namboothiris in Kerala arrived and deceived the Pulayas and Parayas lock, stock, and barrel. With the help of religion. The Namboothiris proclaimed themselves the custodians of all wealth by divine mandate. They possessed the Vedic and Sanskrit mantras and tantras to prove their claims. The aboriginal people of Kerala couldn’t make head or tail of concepts such as Brahmadeya (land donated to Brahmins becoming sacred land) or Manu’s injunctions such as: “Land given to a Brahmin should never be taken back” [8.410] or “A king who confiscates land from Brahmins incurs sin” [8.394]. The Brahmins came, claimed certain powers given by the gods, and started exploi...

The music of an ageing man

Having entered the latter half of my sixties, I view each day as a bonus. People much younger become obituaries these days around me. That awareness helps me to sober down in spite of the youthful rush of blood in my indignant veins. Age hasn’t withered my indignation against injustice, fraudulence, and blatant human folly, much as I would like to withdraw from the ringside and watch the pugilism from a balcony seat with mellowed amusement. But my genes rage against my will. The one who warned me in my folly-ridden youth to be wary of my (anyone’s, for that matter) destiny-shaping character was farsighted. I failed to subdue the rages of my veins. I still fail. That’s how some people are, I console myself. So, at the crossroads of my sixties, I confess to a dismal lack of emotional maturity that should rightfully belong to my age. The problem is that the sociopolitical reality around me doesn’t help anyway to soothe my nerves. On the contrary, that reality is almost entirely re...

Duryodhana Returns

Duryodhana was bored of his centuries-long exile in Mythland and decided to return to his former kingdom. Arnab Gau-Swami had declared Bihar the new Kurukshetra and so Duryodhana chose Bihar for his adventure. And Bihar did entertain him with its modern enactment of the Mahabharata. Alliances broke, cousins pulled down each other, kings switched sides without shame, and advisers looked like modern-day Shakunis with laptops. Duryodhana’s curiosity was more than piqued. There’s more masala here than in the old Hastinapura. He decided to make a deep study of this politics so that he could conclusively prove that he was not a villain but a misunderstood statesman ahead of his time. The first lesson he learns is that everyone should claim that they are the Pandavas, and portray everyone else as the Kauravas. Every party claims they stand for dharma, the people, and justice. And then plot to topple someone, eliminate someone else, distort history, fabricate expedient truths, manipulate...

Mahatma Ayyankali’s Relevance Today

About a year before he left for Chicago (1893), Swami Vivekananda visited Kerala and described the state (then Travancore-Cochin-Malabar princely states) as a “lunatic asylum.” The spiritual philosopher was shocked by the brutality of the caste system that was in practice in the region. The peasant caste of Pulayas , for example, had to keep a distance of 90 feet from Brahmins and 64 feet from Nairs. The low caste people were denied most human rights. They could not access education, enter temple premises, or buy essentials from markets. They were not even considered as humans. Ayyankali (1863-1941) was a Pulaya leader who emerged to confront the situation. I just finished reading a biography of his in Malayalam and was highly impressed by the contributions of the great man who came to be known in Kerala as the Mahatma of the Dalits . What prompted me to order a copy of the biography was an article I read in a Malayalam periodical last week. The article described how Ayyankali...
