Oct 1 2023 I'm always poring over figures I run into. Just this morning, I am trying to make sense of a Madhya Pradesh Government claim that "70.61 lakh farmers get Rs 26 thousand 94 crore 02 lakh". That's Rs 260,940,200,000 to 706,100 farmers, or nearly Rs 370,000 each for each farmer. Is that right? Why then does the text below say "Every farmer receives a total of Rs 6,000 per year"?
Well anyway. It's some figures like these, and some other stuff I read, that got me thinking (agonizing, more like it) about a scientific temper. And that prompted my Mint column of September 22. Wither, scientific temper? https://www.livemint.com/opinion/columns/wither-scientific-temperament-11695403252708.html (Note: I sent it in with a title of "Requiem for a scientific temperament?"; they suggested "Wither, scientific temperament?" which (as someone pointed out) is perhaps grammatically wrong, but I kind of liked it. cheers, dilip --- Requiem for a scientific temperament? ------------------- Dilip D'Souza Every so often, there's news that makes me despair that we will ever build a scientific temperament in this country. This column is about some such news. First, take the truly awful recent front-page report, about two deaths in a small Haryana village. Six years apart, two young women from there fell in love. One, with a man outside her caste. The other, with a man from another village. Both these caused plenty of local annoyance, not least from their own families. You know what's coming. Eventually, the women's own families allegedly killed both. There are some ghastly, nauseating quotes from family members. "How can you be with someone from a village nearby?" asked the mother of one of the murdered women. "Girls cannot interact with men, especially from their own village or from those nearby." The bereaved husband of the other woman listened to his own mother say: "[Their marriage] is a shameful deed. I would have never accepted it." And both households, the report tells us, believed that "you cannot marry someone from the same village because it is like marrying your brother." And if these two murders weren't horrifying enough, we have the Chief Minister of Haryana, Manohan Lal Khattar. Supporting a call to prohibit marriages between people from the "same gotra and village", Khattar claimed such prohibition had "scientific backing". The word "gotra" usually refers to lineage that, to many people, marriage must not violate, for that would amount to incest. I don't want to argue about this, nor chase a precise definition of the word. But to suggest that someone from the same or nearby village is automatically of the same "gotra", as these murderers did, is, by itself and at best, questionable. To murder a woman for such a relationship is a grotesque crime. That a Chief Minister waves away such atrocities is unconscionable. But that he does so by invoking science is profoundly disheartening. He seeks a patina of respectability for an outlook that's indefensible in anyone, least of all an elected official, and he thinks he will get it by tossing us the phrase "scientific backing." No, Shri Khattar, there's nothing scientific here. Just irrational hatred. Second, take a short clip that's making the rounds. It features a young woman interviewing Nitin Gadkari, Minister for Road Transport & Highways, in what looks like a tunnel (https://www.youtube.com/watch?v=LB9MXMEq2WU). In fact, it is indeed a tunnel, being built below the western reaches of New Delhi. Gadkari explains at some length why this tunnel is such a marvel of planning, engineering and cost savings. Judging by the comments the clip has attracted, this has become one more reason to applaud Gadkari's vision and drive. Which is all good, as far as it goes. But in the clip, Gadkari makes two claims that might furrow some brows. The first is that the tunnel is 28km long. The second is about people driving to Delhi airport from Punjab, Haryana and other northern states. Using the tunnel, Gadkari says, they will travel from Panipat to the airport in 20 minutes. One problem: just two days later, there was news of work on this tunnel being "80% complete" ( https://indianexpress.com/article/cities/delhi/dwarka-expressway-tunnel-work-nhai-eight-lanes-expressway-8943148/). The length of this nearly-complete tunnel? Not 28km, but 3.6km. Another problem: Even a quick glance at a map shows that the distance between Panipat and the airport in Delhi is about 100km - most of it along an arrow-straight existing road. What kinds of cars on what kind of road will cover that distance in 20 minutes, meaning at a speed of 300 kmph? My complaint here is not at all about Minister Gadkari. I really don't believe he deliberately made these claims. He just misstated the numbers, and these things happen. No, my complaint is instead with the woman who interviews him in the clip. By not challenging these absurd numbers right there - as any reasonable journalist must - she allows them to stand. One more opportunity lost, for a simple reality check involving simple numbers, maybe even a simple look around her. When it comes to numbers that they run up against, why are so many journalists so willing to ask no - zero - questions? Third, a mathematician called CK Raju spoke at the Vivekananda International Foundation in New Delhi a few days ago. One report ( https://theprint.in/science/einstein-was-a-fraud-west-stole-calculus-from-india-mathematicians-claims-slammed-by-peers/1763474/) about this event started with these two lines recounting some of what Raju spoke about: "Albert Einstein was a fraud who never really understood relativity. Euclid never existed; he was an invention of the Church. And modern mathematics is religious propaganda of the West that stole calculus from Indian 'ganita' without understanding it." Raju went on: "Einstein did not discover the theory of relativity ... he was a clerk at the patent office who stole ideas from others." And "ancient Indian mathematics" - 'ganita' - is superior to "Western ethnomathematics." Raju's overall effort is one I - again - have no complaint with. He wants to show that Indian mathematics has a long, storied heritage, with plenty of stellar discoveries to its credit. Now there's plenty of truth there. Aryabhata found a way to calculate the value of π accurate to four decimal places - a value good enough for nearly every purpose you can come up with, even today. He also concluded that the apparent motion of the stars was due to our own planet's rotation. Hemachandra knew of what are called Fibonacci numbers in 1150, half a century before Fibonacci wrote about them; and in fact, other Indian mathematicians described them as early as 200 BC. There's a lot more in that vein. The question, though, is this: to make this case about the achievements of Indian mathematics, is it really necessary to denigrate Western mathematics? Is it really necessary to call one of the greatest minds of the 20th Century a "fraud"? So when he does these things, what can we conclude about Raju's confidence in his own words? Besides, the way of science is to recognize what others have accomplished and build on it. This is why Isaac Newton so famously said: "If I have seen further, it is by standing on the shoulders of giants." When we instead kick away those shoulders, what does that say about a scientific temperament? -- My book with Joy Ma: "The Deoliwallahs" Twitter: @DeathEndsFun Death Ends Fun: http://dcubed.blogspot.com -- You received this message because you are subscribed to the Google Groups "Dilip's essays" group.
