[Goanet] VERY WARM GANESH GREETINGS TO YOU ALL
In this great Festive Season, let us all very sincerely pray in an extremely special way to Lord Ganesha, the Vigna-harta (remover of obstacles) to please help ease the never ending sufferings of the poor and needy across Goa. After having left the entire State with potholed roads in this festive season, may also those obstacles in the path of those currently misruling and ruining the remains of our Goa just multiply manifold. Tathastu, so be it. Let us cherish the friendship and warmth of friends hailing from all creeds, communities and castes. We are all on a short voyage in this world, the end of which we know not. So let us live and cherish every day we have caring and loving the entire community at large. The Political arena cannot be about personalities or religious and caste differences. It is much more than that! We need to rectify the decades of willful neglect and stagnation of Goa by ensuring that we have politicians of competence, honesty, dedication, experience and selfless determination above all else. We must always firmly believe that Temples, Mosques and the Churches besides other places of worship should be our focal points to unite diverse communities instead of creating rifts amongst us. We are after all children of that one loving and extremely tolerant God. Adv.

[Goanet] {Dilip's essays} An aging country considers its soldiers
Sep 1 Some weeks ago, the government announced a new scheme to recruit young men for our armed forces: Agnipath. This set off a wave of debate and protests and demands for it to be rolled back. I'm not sure that will happen, but there are questions that remain about Agnipath. This scheme has a lot to do with something other countries are also grappling with: how do we pay pensions to an aging population? And that's what prompted this column I wrote, considering this issue via some numbers. An aging country considers its soldiers, https://www.livemint.com/opinion/columns/an-ageing-country-considers-its-soldiers-11661447080721.html Do let me know what you think. cheers, dilip PS: Aging? Ageing? I used the first in my draft (below), it got changed to the second in print and online. --- An aging country considers its soldiers What's one thing you can say with certainty about countries that "develop"? Meaning, broadly, countries that manage to raise their per capita income numbers? Probably many things, but what I'm getting at in asking that question is this: such countries grow older. That's because increasing wealth brings desirables like greater levels of education and healthcare, lower birth rates and longer lives lived. When you have relatively fewer people born, and if the people already born live healthier and longer lives, it's easy to see the result. In a nutshell, over time, you have fewer younger people, more older people. So with India. We talk about our "demographic dividend", meaning the large pool of youths in the working population, and it's real. But there are two ways to consider that. One, the young have always been a large fraction of India's population, meaning we've always had this demographic dividend. Two, this particular dividend is steadily eroding, because we are a steadily aging population. Here are just a few random figures to support this statement. Life expectancy rose from just over 40 at Independence to about 70 today. From 1971 to 2001, the fraction of our population aged 35-60 rose from 21.4% to 22.2%. If those seem like ancient history to you, I'm only tossing them out to show that India has been aging for decades. Still, you want more recent numbers, so consider what's happened between 2011 and now. Indians over 65 years of age were 5.17% of the population in 2011: that number has steadily risen to 6.78% last year. Indians under 14 have gone from 30.4% of the population in 2011 to 25.78% last year. Finally, there's our recently trumpeted Total Fertility Rate (TFR), the number of babies the average woman expects to produce in her lifetime. Trumpeted, because the TFR has dropped to just over 2 today, from nearly 6 at Independence. Less babies: fewer young people. For the TFR, 2 is considered a significant milestone, because it is "replacement level". If every couple produces two babies, they effectively replace themselves, no more. That means the population will stabilize. (Strictly, replacement level is taken as a TFR of 2.1, because some babies die. But let that be.) All these numbers, to underline the point that as India "develops" - a desirable goal, you'd think - we are also becoming an older society. That simple reality comes with various consequences that we have to find ways to cope with. Consider one of those. My father had a long and successful career in the IAS. When he retired at 58 in 1979, he was Secretary in a Central Ministry - that is, at nearly the top of the IAS hierarchy, of his profession. His salary then was Rs 3500 per month. It's an amount that seems almost laughable today, but in 1979, it meant something substantial. In retirement, the government gave him a pension. When he died in 2007, the pension transferred to my mother, at half the amount my father was getting. She started with Rs 16,500. Various cost-of-living and pay commission adjustments mean that 15 years later - and 43 years since my father retired - my mother's pension is just over Rs 100,000 a month. There's more, too. Before the IAS, my father spent three years in the Navy. By the time of his death, his pension for that service was Rs 17,000 a month. You might do some calculations to compare these increases to inflation; to find out how much my parents have cost the national exchequer; to know, too, that the pension has lasted 11 years more, already, than my father's entire career in the IAS. In any case, you might remember that this is how a nation chose long ago to thank my father and other Indians like him for their service. Perhaps you see where this is going. The government is concerned about the growing cost of pensions for our military personnel. Concern apart, why this growth? Precisely because India is aging, as detailed above, meaning more pensions must be paid, and for longer periods. I don't know how military pensions are decided, but I imagine it must be a similar calculation to pensions for bureaucrats like my father. Whatever it is, we are told that
[Goanet] {Dilip's essays} How far is that oldest object, really?
Sep 1 Catch-up mode, again. My last dispatch here was about the discovery by the James Webb Space Telescope of the oldest object we humans have ever observed, a certain smudge in the sky named GLASS-z13. Also the furthest object we've seen. (Meet the oldest object ever seen, https://www.livemint.com/opinion/columns/meet-the-oldest-object-ever-seen-11659639047752.html ) To me, that's profoundly intriguing by itself. But it does raise questions: how do we actually deduce how old it is, how far it is? Some of you probably know the answers, I'm sure - they have to do with the Doppler effect. Still, after writing that last column, I thought I should write a followup trying to explain this astronomical calculation that's so fundamental to how we look out at the universe. So this column (Friday Aug 12) was the result. How far is that oldest object, really? https://www.livemint.com/opinion/columns/how-far-is-that-oldest-object-really-11660245731482.html cheers, dilip --- How far is that oldest object, really? My last column in this space referred to the oldest object we humans have ever observed. That's the galaxy GLASS-z13, which the James Webb Space Telescope focused on last month. Light from GLASS-z13 has taken 13.4 billion years to reach us, which means we are seeing it as it was that long ago. That makes it, indeed, the oldest object we've ever observed. It also means the galaxy is 13.4 billion light years away. Or is it, really? That column pointed out that "astronomers estimate [GLASS-z13] is now actually about 33 billion ly from us." How do they know this? Try this thought experiment. I sit opposite you, blowing a sharp and quick note on a whistle every second. You'll hear the note every second, no drama there. Now suppose I'm actually sitting in an aircraft. I continue to blow the whistle every second, but after my first whistle note from opposite you, the plane travels away from you at the speed of sound, which is about 1250kmph, or 350 metres per second. How frequently will you hear the whistle? (Assume for the sake of this experiment that you can indeed hear it.) Well, the second time I blow it is after one second, but by then I'm 350 metres from you. That sound will take a second to reach you - so you hear my second note two seconds after the first. You might say, the frequency of the notes has halved, from one every second to one every two seconds. Similarly, if the plane was flying towards you instead, the frequency would double. This is a simplified way to think about the well-known Doppler Effect. Sound travels in waves. If the source of the sound is moving away from you, those waves lengthen, their frequency dips, and the sound becomes lower-pitched. The opposite, if it is moving towards you. The classic example, familiar to us all, is the horn of a passing train. Its pitch lowers as it speeds away from us. In fact, my whistles from the moving plane will also be lower in pitch than the first, sounded before the plane started moving. What does all this have to do with GLASS-z13 and how far from us it is? As I mentioned in my last column, there's a clue in that "z13". That is a measure of what astronomers call "redshift", or a change in the frequency of light. Like sound, light is also made up of waves. (It's a little more complex than that, but let that be.) When light comes from a source that is moving - like my whistle in the plane - its wavelength changes like sound's does. If the source is moving away, the waves lengthen (and their frequency decreases). When that happens on the sound spectrum, you get a sound at a lower pitch. With light, you get light that's nearer to the red end of the light spectrum: thus "redshift". The opposite, if the source is moving towards you: thus "blueshift". You should wonder here: how do we detect this shift, whether red or blue? It's not exactly that the light from the distant source suddenly looks redder or bluer. Instead, it has to do with substances the object is made up of - like iron, or carbon, or magnesium. When you heat such a substance, it emits light. A spectroscope (aka spectrometer and spectrograph) uses a prism to break up that light into a spectrum, in the same way that rainbows form from "white" light. Each such substance produces its unique pattern of lines in that spectrum, each line at a specific frequency. So if you find the telltale lines of iron in a spectrum, you know there's iron in whatever your spectroscope is pointing at. This fingerprint, if you like, is how we know the chemical composition of faraway celestial objects. Here's the fascinating thing. When astronomers first used spectroscopes on the light from distant stars and galaxies, they recognized fingerprints in the spectra, the characteristics of different substances. But to their surprise, in every case these spectral lines were shifted along the spectrum. Which leads to this remarkable conclusion: these distant objects are moving. Not just that; since
[Goanet] {Dilip's essays} Beware the swooping hawk
Sep 1
A few times in my life, I've spent a happy few hours perched at one end of
an airport runway, watching planes land and take off. Maybe this doesn't
really catch your fancy, but I've always enjoyed it. The first time,
though, I came back with my fingers nearly frozen off. Really. Some 45
years later, I still remember that pain.
But that apart, the whole business of landing one of these machines always
contrasted, in my mind, with how birds land - much more gracefully and
efficiently. Why? And while there are some planes that more closely imitate
what birds do, we're still a long way from exactly what they do, if we ever
get there.
So this column (Aug 19) is about some research into how birds fly towards a
landing. Take a look:
Beware the swooping hawk,

---
Beware the swooping hawk
One February morning in Delhi was the first time I did something I've done
a few times since. I rode my bicycle to one end of the runway at the
airport and stood there for a couple of hours, watching planes land and
take off. I remember that very clearly, but not really because of the
planes. Riding home, my fingers got so cold that I feared they would fall
off. Seriously.
Still, the planes. Both take-offs and landings were exciting, but the
landings were far more intriguing. At some point afterward, I began
wondering - when they descend from the sky, why do these flying machines
need a long runway to slow to a stop? After all, their very creation was
inspired by birds. With few exceptions, birds are able to transition from
flight to perching on a branch in an instant. Admittedly, they are much
smaller and slower than aircraft, and thus easier to stop. Even so, what is
it about the flight of birds? Do they have some special mechanism in their
wings and muscles that we have not (yet) been able to replicate in our
planes?
True, different birds behave differently while coming to a halt. Watch
flamingos swoop in to land in shallow water, and it's almost as if they run
along the surface for a few steps before settling - reminiscent of planes
using a runway. But there are small birds like sparrows or flycatchers,
which seem to hover for a moment right before sinking onto a twig. Or
larger ones like hawks and kites, that will actually swoop up from below to
perch.
I know this partly from watching plenty of birds on the trees near my home.
But also because, as you have probably guessed, there are scientists who
have studied the flight of birds. In particular, how they land. A recent
paper in Nature, for example, begins thus: "Perching at speed is among the
most demanding flight behaviours that birds perform and is beyond the
capability of most autonomous vehicles" ("Optimization of avian perching
manoeuvres", Graham K. Taylor et al, 29 June 2022,
https://www.nature.com/articles/s41586-022-04861-4).
Beyond the capability of, for example, planes.
The paper says researchers tracked the flight paths of four hawks - not
once or twice, but nearly 1700 times over distances of 5, 7, 9 and 12
metres. Three were young males, "initially naïve to the task"; the fourth
was "an experienced adult female." They flew these distances tempted by
food the scientists made available at flight's end.
And what did they find? For their first few flights, the naïve birds
flapped their wings and flew more or less directly across to the food. But
only those first few flights. After that, some innate hawk instinct took
over and they followed the technique more experienced birds - like the
adult female - used. It went something like this:
The hawk leaps from where it is stationed, a post about 1.25m tall. It
dives forward and downward, using "several powerful wingbeats" to do so. A
little over halfway to the food, it has sunk to as low as just 35cm off the
floor. But from that nadir, it climbs upward to the food. Its wings do
hardly anything during the climb apart from limited moves to correct and
control the flight. This "unpowered climb" is essentially a glide, using
the momentum of the earlier dive to move forward and upward. As the bird
nears the perch, it switches mid-flight to a position in which its body is
nearly upright, its wings are outstretched and its feet are held out in
front to grab the perch.
Thus lands the hawk. Seen from the side, its flight path is a shallow "U",
the swoop of its trajectory unmistakable. But why this "U"?
The researchers report that after a session of these experimental flights,
the birds were "usually panting visibly." You might conclude that while the
hawks fly at relatively slow speeds over these relatively short distances,
those powerful wingbeats use up a lot of energy. The slower a bird's
flight, after all, the more it needs to flap its wings, the less it will
glide. This is why the hawk dives at the start, you'd think, using
