Common Sense

 


“Are you interested in popular science books?” He asked me as I put down Carlo Rovelli’s Reality is Not What It Seems in my lap to think about what I had just read: “… great science and great poetry are both visionary, and may even arrive at the same intuitions. Our culture is foolish to keep science and poetry separated: they are two tools to open our eyes to the complexity and beauty of the world.” That was what had caught my attention particularly. That was very much in tune with my own thinking. I took interest in science precisely for this reason.

I told the fellow passenger the same. He was impressed. We were both on a train.

“My name is Ananthapadmanabhan,” he said. “Pretty long, isn’t it? They call me Pappu, for short.” And he laughed. The name Pappu is in North India what Sasi is in Kerala: Dunce.

“People like to compartmentalise truths,” Pappu said when I told him about my limited interest in science. “It makes life easier. Use science for practical life and religion for morality and poetry for beauty. Pretty easy. If only we would care to realise that all these are not so conveniently separated systems.”

“It is because of these compartmentalisations that we have so many problems,” I reflected loud.

“Indeed,” Pappu conceded readily. “Just imagine the religious bigot applying physics to his fervour.”

“Physics would have provided a better trajectory to his heaven.”

Thus went on the conversation until Pappu gave me a classical problem to work out.

“Two trains start from opposite stations, say Station A and Station B, at the same time. The distance between A and B is 150 km. The trains move at the same uniform speed of 50 kmph. A bird starts flying too from Station A at the same time at the uniform speed of 100 kmph. When the bird reaches Train B, it turns around and flies back to Train A. When it reaches A, it turns back again and flies to B. And so on. How much distance will the bird have flown when the trains pass each other?”

I had worked out similar problems as a young man. I used physics and simple arithmetic for that. Here too I set upon thinking in the same way. When the trains travel 50 km each, the bird will have flown 100 km. So the bird reaches Train B at its 100th km. The trains are still 50 km away from each other when the bird turns around. Now the bird will fly around 33 km (double of what each train will run) to reach Train A and the trains will have moved some 17 km each. A bit of arithmetic will tell us that the bird will fly distances of 100 + 33 + 11 + 4 + 1 km (approximately) which adds up to 150 km.

“That is quite a mindboggling arithmetic,” Pappu said. “You made it very complicated by bringing in geometric progression and all that stuff. It’s much simpler, you know. See. The trains are moving at the same uniform speed of 50 kmph. It means they will meet exactly in the middle of the total distance. That is at 75km. The bird’s speed is just the double of each train’s. So when each train covers 75 km, the bird will have flown 150 km.”

Cute, I thought.

“Very often we make things complicated unnecessarily,” Pappu said. “If only we make use of our common sense, life would be much simpler.”

Our train was approaching the next station where Pappu was to alight.

“Remember D H Lawrence?” He gave me a parting shot. “I despised myself and the voices of my accursed human education.”

    Similar thing is said about science and spirituality that they meet eventually.

      Thank you. But we don't come across Pappus every day. 😊

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 Little Girl

The Little Girl is a short story by Katherine Mansfield given in the class 9 English course of NCERT. Maggie gave an assignment to her students based on the story and one of her students, Athena Baby Sabu, presented a brilliant job. She converted the story into a delightful comic strip. Mansfield tells the story of Kezia who is the eponymous little girl. Kezia is scared of her father who wields a lot of control on the entire family. She is punished severely for an unwitting mistake which makes her even more scared of her father. Her grandmother is fond of her and is her emotional succour. The grandmother is away from home one day with Kezia's mother who is hospitalised. Kezia gets her usual nightmare and is terrified. There is no one at home to console her except her father from whom she does not expect any consolation. But the father rises to the occasion and lets the little girl sleep beside him that night. She rests her head on her father's chest and can feel his heart...

Mother Mary Comes to Me

Book Review In one of the first pages of this book, the author cautions us to “read this book as you would a novel.” No one can remember the events of their lives accurately. Roy says that “most of us are a living, breathing soup of memory and imagination … and we may not be the best arbiters of which is which.” What you remember may not be what happened exactly. As we get on with the painful process called life, we keep rewriting our own narratives. The book does read like a novel. Not because Roy has fictionalised her and her mother’s lives. The characters of these two women are extremely complex, that’s why. Then there is Roy’s style which transmutes everything including anger and despair into lyrical poetry. There’s a lot of pain and sadness in this book. The way Roy narrates all that makes it quite a classic in the genre of memoirs. The book is not so much about Roy’s mother Mary as about that mother’s impact on the daughter’s very being. Arundhati was born in the undivided ...

The Real Enemies of India

People in general are inclined to pass the blame on to others whatever the fault.  For example, we Indians love to blame the British for their alleged ‘divide-and-rule’ policy.  Did the British really divide India into Hindus and Muslims or did the Indians do it themselves?  Was there any unified entity called India in the first place before the British unified it? Having raised those questions, I’m going to commit a further sacrilege of quoting a British journalist-cum-historian.  In his magnum opus, India: a History , John Keay says that the “stock accusations of a wider Machiavellian intent to ‘divide and rule’ and to ‘stir up Hindu-Muslim animosity’” levelled against the British Raj made little sense when the freedom struggle was going on in India because there really was no unified India until the British unified it politically.  Communal divisions existed in India despite the political unification.  In fact, they existed even before the Briti...

Insecurity and Exclusivism

“ Hindu khatare mein hai.” This was one of the first slogans that accompanied the emergence of Narendra Modi on the national scene. It means Hindus are in Danger . It reveals a deep-rooted feeling of insecurity. Hindus constitute an overwhelming majority in India – 80%. All the high positions in governance, judiciary, academics, any significant place, are occupied by Hindus. Yet the slogan was born. Strange? It will be facile to argue that Modi used this slogan and its concomitant hatred of Muslims and Christians as a political weapon for winning votes. True, he was successful in that; he rose to the highest political post in the country using minority-bashing. But the hatred did not end with that achievement; rather it spread outward and became more exclusive. Muslim and European rulers of India were booted out from the country’s history books and wherever else possible like the names of roads and institutions. With vengeance. Now there is a concerted effort going on to place In...
