Post election thoughts

 It shocks me that people are shocked about the result. Just like the last edition the two main points are the same. 

1. At a macro level, we did not learn anything new about American voters. There were some subtle shifts in demographics and rural voters turned up more, but let's look at the difference making states:

2016: Trump won because he got MI by 0.23%, PA by 0.72% and WI by 0.77% . Total < 80k votes

2020: Biden : GA by 0.23%, AZ by 0.31% and WI by 0.63% . Total < 42k votes (note: if Trump had won these states it would be 269-269 and he had the tiebreaker in his favor)

2024: Trump : MI by 0.5%, PA by 1.9% and WI by 0.9%. Total < 240k votes . Is that a large number? No : Just 0.16% of those who voted or 0.1% of all eligible voters.

At a micro level, some voting patters (e.g. Latino, Black men) shifted every so slightly, the Gaza issue alone lost Michigan for Harris, etc, but these are still small contributors to the overall numbers.

2. Poll synthesis was quite accurate. Just like in 2020, each candidate comfortably won each state they were supposed to win, and Trump won (almost) all the toss up states by tiny margins within the margin of error. You could argue that most states were off by about 2-3% in Trump's direction. Well.. that is within the margin of error, and the best pundits (e.g. nate silver, nate cohn) kept saying that the toss ups are likely to go in one direction. I think that direction is easy to guess, because they also said Trump voters were less likely to respond to polls.

In summary, pay attention to polls, look at margin of error, and don't dismiss them in the 'paid off' category.

What about the Senate? Exact same story (and more even in the tossups).
What about the house? Exact same story (and more even in the tossups).

For a situation this complex, with so many issues, the good pollsters are remarkably accurate. It is quite insane that there are no big upsets among any state/house seat/senate race ! Just like last time.


Michigan

The total voting number was pretty much the same as last year. Some rural counties went more red this time, and Trump won by 80k votes this time. The entire margin comes from Wayne County (basically Detroit) where almost the same number of voters showed up. Biden was +332k last time. Harris is +250k this time. My county voted almost exactly the same in 2020 and 2024 (almost 75% Blue each time).

Some nuggets from our school reunion

We recently had a wonderful 31st year reunion of my secondary school (10th standard) class (and teachers, all of whom showed up!).  We started by visiting the school at 8:30am, got to the venue at 10am and the event went on until 6pm (of course followed by an afterparty). The teachers seemed to enjoy it so much and were fully engaged (and didn't budge until 5:00pm).  Everyone in attendance had a chance to give a speech and there were a number of beautiful moments that I feel compelled to document (and share) a few nuggets from my already fading memory.

- Our math teacher began her speech by addressing us as "Children" - just like old times. Spine-tingling.

- Our class was the third oldest in the school's history, and so we had joined a very very young school with just 7 teachers and a few classes. So - outside of one or two exceptions - our teachers were very young, very inexperienced and pretty nervous to teach (now we know!). They just figured it out on the fly, and got better and better every year. They also worked damn hard (teaching 6 hours a day) and cared for us. I remember the effort they put into organizing school events (annual day, plays, sports day, etc.) - By the time we reached 10th grade, the quality of instruction was quite good - by any standard. I remember Biology and Math to be particularly exceptional - again, by any standard.

- Teachers seemed to not only remember us, but recounted memories that some of us didn't (including the time I sent one of them a personalized greeting card (analog version of photoshop). From 35 years ago.  I think the size of the school, the youth of the teachers (and the school) made for a family-type atmosphere. Besides, the headmaster (who was present at the reunion) was also very tactful in getting things done without ever being pushy. That made the teachers more committed. I remember getting on a bike with some of my friends and randomly visiting 2 or 3 different teachers at their homes over weekends. This wasn't an exception, and even those students who were regularly "punished" seemed to get along well with the teachers. All of this contributed to us having very fond memories of our beloved school.

- Since matriculation schools were somewhat prestigious (and had a hard syllabus), apparently such  schools only admitted students from educated families. Our school did not discriminate and had a pretty diverse class. Teachers shared stories about how much effort they put into educating students (admittedly they were working towards achieving a 100% pass rate). One of the teachers shared a touching anecdote : Some students could not study at home because of "problems." So the school gave them a room to stay, fed them in the canteen and gave them extra lectures. 😇 They did achieve 100% pass rates year after year (and in my class, 34 out of 35 students secured first class).

- Most of the teachers were very strict back in the day, and one of them said "I think about your lot once in a while and always assumed that you all will be somewhere swearing at us. I did not, for the life of me think you'd organize this beautiful event and shower us with love." One of the teachers said "Sometimes I wonder whether I was too strict and how that may have affected your development." Of course, almost all of them lamented the relative lack of control they had over succeeding generations, although our Physics teacher,  still active at a convent school, and still calls some students as "donkeys." One of my classmates recollected that she used to waltz into class pointing to him and two others as "Donkey #1, Donkey #2, Donkey #3, stand up on the bench." 😂

- Our English master  (a really cool guy, then and now) was apparently educated in a Tamil medium school and said that he barely passed his English in high school (70/200). He joined us right after his M.A. and recounted his very first lecture: It was a lesson titled 'The Banyan Tree'. He apparently pronounced it as 'The Bunyan Tree', and he was immediately corrected by a student in our class. "It is not a bUNyan tree - it is a bAANyan tree." He said he was terrified, but handled it OK.  We had him for our final 3 years and I remember him to be really good at teaching and to be very engaged with us in and out of class.  I vividly remember his in-class grammar exercises (something about main clauses and subordinating conjunctions) would be on text extracted from current news articles. He recently retired from a long and distinguished career (eventually got a PhD in English literature and was headmaster at various schools for more than a decade, of course very popular wherever he was). He recounted number of things in his career based on experience he gained from a few years at our school.

- We all remembered our Tamil and Hindi teachers to be so calm, collected, and even-keeled. Or so we thought. We just learnt that they were incredibly shy (so shy that they won't even talk much with other teachers) and borderline terrified of us. Our Hindi teacher shared this "I had to walk 20 minutes to catch a bus with the Tamil teacher. One day I was wondering whether she would even begin a conversation. I didn't say a word, and she didn't either."

- We felicitated the teachers, received their blessings, and of course, all of them gave us children advice on everything from "never stop learning" to "how to bring up kids" to "how to control our temperament."

- My aunt was a prominent teacher in the school. One day she asked one of my friends to meet her in the library. He thought he was in trouble but he recounted the following "I hear you are Karthi's best friend. As you know, his birthday is coming up. Can you give me ideas for a gift?"

- We made a trip to the school and the current principal (a very energetic lady, who also made the time to spend a few hours at the reunion) greeted us pleasantly, and gave us permission to roam around, even when classes were in session. Funniest moment was when she said "I am proud and privileged to meet you all, especially because you are 10 years older than me." 

So yeah.. in summary I think it was memorable enough to spur an average of 800 whatsapp (no exaggeration) posts a day over the past week in our school group.

A punctuated life story of a terrible sports fan

Lionel Messi's world cup win was a beautiful thing. This short article captures the essence of it and references `late style': "the final works of a composer or writer—when the decay of the body can’t help but inform artistry, when creativity is infused with the bumps, bruises, and wisdom of a life almost fully lived." For this crowning achievement to transpire  - after so many close calls - near the end of one of the greatest careers in the history of sports, in the greatest final of the biggest event in sports is poetic. It also turns out to be the thing I cared most about as a sports fan, and given so many prior heartbreaks, to have a favorable outcome in this manner is beyond belief.  

I have always been quite fascinated by the neurochemistry of why and how sports affects me in a particular way, and though it is controllable, I let it be for the heck of it. In any case, as I prepare to retire from a life of fanatical and hysterical sports-watching, I felt like recounting some visceral experiences, viewed via the lens of the past 10 world cups. 1990 was when I officially became a teenager. In a certain sense, 2022 is when I think I can finally stop being a teenager.

May 1986. My dad brought home an issue of 'The Sportstar' that previewed the World Cup in Mexico. I still vividly remember the feature page that had a photo of a sombrero-wearing kid with a football in hand and the Azteca pitch in the background, and reading about an earthquake that had happened a few months eariler in Mexico. I had never heard of the World Cup nor had I ever watched or played football. He told me how big a deal it was to the world. A REALLY big deal. I absorbed that information, but didn't watch the matches. Some context here : '86 was when most people in India were able to watch a football world cup on TV and consequently Maradona became the idol for hundreds of thousands of Indians. I took up football and eventually played for my school team circa 1989.  Sometime between 86 and 90, I got into watching sports seriously: Cricket (India), Tennis (Agassi),  and Football (Maradona/ Argentina). Later this madness/addiction extended to Maryland basketball, Federer and sometimes the NBA (Chris Webber's Kings were my first love). 

The following 32+ years have been an emotional rollercoaster (as cliched as that sounds, I think it is on point), punctuated by very rough landings every 4 years, though there were some real highs like Federer, Maryland basketball and Indian cricket. However, my intensity also made me a terrible sports fan. Tip of the iceberg: Since 2014 (or was it 2015?) I have developed a habit of not being able to watch parts of games (not just soccer, but also Basketball, Tennis, etc) when things don't go my way or even if is close to 50/50 and too tense. Example: In this world cup, I did not watch the last 40 min of the Saudi Arabia game, the first 63 min of the Mexico game, the time between Messi's penalty miss and Argentina's first goal in the Poland game, and about 20 minutes of the WC Final. Thus, this is the story of a terrible, hysterical sports fan who finally retired happily from terribleness and (potentially most of) the hysterics on December 18th 2022. 

July 1990 Final 0-1 Germany. In the buildup to Italia '90, I started rooting for Maradona and Argentina. This was accelerated by the shocking opening round loss to Cameroon which is also the first time I remember crying over a sporting event. As the match was winding down, I remember pulling up a bedsheet over my face and quietly sobbing. My sister knew though. Argentina recovered somehow, and played (very) ugly yet gritty football all the way to the final. The final was, however, a disaster. Two Argentines sent off, and Germany won on a penalty. By the end of the world cup, my obsession with Argentine soccer and Maradona was well and truly underway. I don't know the particular reason why, but let's say it may have had something to do with his skills and passion (it was a sight when one of the best players in history is crying uncontrollably) and plainly and simply - my neuro-receptors were just about ready for obsession.

July 1994 R16 2-3 Romania. By now, sports was central in my life. I would start every day by reading the entire sports section in the newspaper. At least until 2000, I could narrate the score of each of the 64? games played in the '94 world cup. In fact, I still remember the scores from the QF, SF and Final. After an incredible start to the tournament led by a rejuvenated Maradona, the team fell apart when #10 was suspended for taking ephedrine. The R16 match was a great one for the neutrals but when Hagi made it 3-1 in the 2nd half,  it was curtains. Maradona was excited (from the stands) when it was 3-2 with about 15 min to go, but that's how it ended. I was watching this with my cousin who was an ideal foil for my vices at that time. I'd closely follow the end of Maradona's career.

July 1998 QF 1-2 Netherlands. This was a good, but not great Argentine side which had gotten by England in an absolutely thrilling 2nd round match. This game was tied 1-1 and Ariel Ortega (incredible dribbler and great playmaker) went down in the box for what I thought was a penalty. Instead he was sent off for diving. In the very next minute - before I could absorb that shock - one of the greatest goals in world cup history happened. Dennis Bergkamp (one of my favorite players) controls a 80 yard pass and shoots, all in one incredible move. Stunner. I was watching this at home and some younger (and adoring) collegemates had come over. After this goal though, I went upstairs, and refused to speak to anyone. The guests even tried to console me, but I didn't speak to them or anyone for about 24 hours. 

June 2002 Group stage 1-1 Sweden. Argentina arrived at this world cup as the favorite to win it all. The team was fabulous: Crespo,  Veron, Ortega, Simeone, Zanetti, Ayala and Co. were at the peak of their powers, and Batistuta was still very good (and scored in their only win). Bielsa was considered one of the best coaching minds. But it just never worked, and I remember the team not having width when attacking. Needing a win, they were able to tie Sweden in the 88th minute, but no joy. This was in my shared grad student apartment in Maryland perhaps past midnight. I was devastated.. took a walk and remember seeing a guy in an Argentina jersey who seemed even more sad than me. Then I drove up to Baltimore airport and back for no reason.

June 2006 QF 1-1 (2-4) Germany. This was again a great squad with a good coach (Pekerman) and among the favorites. Argentina took the foot off the gas pedal after they scored, only for Klose (oh! I hated him) to equalize and lose on penalties with Messi on the bench. I was flipping mad. Vidya's best friend was visiting, but they knew enough to leave the house before the game, and Vidya claims that they came back to see some of the furniture upside down.. and left home again. I suspect I must not have been in a good mood for a few days.

July  2010 QF 0-4 Germany. This was a very good squad with amazing young players (including Messi Di Maria, Tevez, Aguero, Higuain), but it was coached by someone who was terrible at his job (Maradona! and I had was at his international coaching debut in Glasgow and came within 2 feet of him). Nothing much to say except it felt incredibly embarrassing. It seemed like the European brand of soccer finally overtook the South American brand (Europe had never won 2 in row until now). Vidya was (more than) a legit soccer fan by now, was watching and could understand.

July 2014 Final 0-1 Germany.  I was watching this in downtown San Francisco in a wonderful outdoor setting with thousands of fans (98% of whom were supporting Argentina). Argentina had a good but not great squad. But they had prime Messi and improved throughout the tournament and became really solid by the final match, especially on defense. I erupted with the crowd when I thought Higuain had scored in the first half. He infamously missed another open chance in the 2nd and Messi had missed a harder but makeable opportunity. Germany had more of the ball, but Argentina clearly had the better scoring opportunities. Deep into extra time, I saw a dangerous looking situation and closed my eyes. When I opened my eyes, I learnt that Gotze had scored.  I immediately walked towards the car, texted a postdoctoral fellow (whom I had driven to the game) to come to the car and didn't speak for about an hour. It was quite simply devastating it looked like 24 years of pain had vanished. The worst day of my life as a sports fan (in retrospect, not anymore). I only mustered the courage to watch the goal 7 years later (after Messi won the Copa America).

June 2018 R16 3-4 France. Argentina had a bad start to the tournament and sneaked into the 2nd round against a really good France team. This is the only Argentina WC match I haven't watched over the past 32 years. When this match was on I was flying on a Cessna over Northern Michigan to a party and was following the score on a spotty internet connection. I was ready to jump off the plane when Di Maria gave us a 2-1 lead, but alas.... France was too good that day. I was disappointed, but not distraught. I had a decent day overall with normal behavior, attended a nice party and it got even better when Portugal lost to Uruguay. By this time, Messi had lost 4 international finals, getting to the end of his career and winning something big (even the Copa America) seemed impossible because Argentina did not have the quality of players they had in the 90s and early-mid 2000s, and seemingly the gap between Europe and South America was unbridgeable now.

Dec 18 2022. Final 3-3 (4-2) France. Things did start to look a bit different in the Summer of '21 when Messi won his first senior-level international trophy and appeared unchained. But still, this was just the South American championship and the game has recently been ruled by Europe. Besides, there were at least 5 other countries that had better rosters than Argentina. Despite the bad/unlucky start to the tournament, Argentina consistently got their tactics right, Messi was playing at a very high level and the pieces around him fit really well. Going into the final, it was clear to anyone that it was going to be one of the most significant games ever played in any sport. The fact that it was Messi's last shot itself was big enough, but how about a GOAT candidate's chance to be placed alongside Maradona vs a younger star who would surely be placed alongside Pele if he won...not to mention the possibility of back-to-back WC wins..and.. the Golden ball and boot were in play. We watched the game in a (fellow maniac) friend's house with a number of Argentina fans. They had TVs in 3 different rooms and several bedrooms at our disposal to watch/suffer in our own terms, or to have a moment or just to go sulk or take time off. Boy did we all use those amenities or what? It was pure mayhem, with lots of hugs, kisses, kids being thrown in the air, groans, moans, etc Argentina dominated the match and should've won easily, but some mistakes almost sunk them. The ecstasy (x2), the agony (x2), the ecstasy, the agony, THE SAVE and when the last penalty was scored, I finally felt so light. Despite some of the aforementioned lows, sports has always been net positive, and greatly enriched my life experiences. But for this particular fairy tale to have the best possible ending makes it the best day of my life (and my wife approves ha!).  As the impossible seemed possible a couple of weeks ago, I had declared that I would retire my sports fanaticism, and finally grow out of my teenage years. #micdrop.

Greatest accomplishments of "Independent India"

For a people and a region that has contributed to human advancement as much as (or more than) the Greeks and the Romans combined, talking about 75 years of Independence makes India appear younger than a young country like the USA. This period is, however, a good marker for modern India.  Below, I've opined about the 5 Greatest achievements of the past 75 years.  Perhaps more importantly, I've dropped some references for you to look up. I will write a second post on the 'Also Great' list soon. 

I do have to start with the disclaimer that all issues are in grayscale, and so there is always something to complain about even in our admiration. Also, this is just about the past, and there is no guarantee that all of these won't erode (in fact, some of it may already be) in the next few decades. In any case...

The Constitution & stability
The Indian constitution is a remarkable document in how forward thinking it was. Indeed, truly living up to the aspirations of the constitution is quite impossible (as in any country), but it is well-crafted, nuanced and progressive.  This document has to be viewed in the context of 1947:
- An incredibly diverse population (22 major languages - each much more dissimilar to each other than the major European languages are to each other - and many more cultures make this more of a continent rather than a country)
- A shaky union including 562 princely states 
- Extreme poverty (70%) 
- Extreme illiteracy (12%)
- Psychological impact of British rule & the trauma of partition

Against this backdrop, the constitution set the stage for a stable and functioning democracy, with remarkably stable transfer of power every single time, and of course, reduction of inequality via reservation (aka affirmative action). Literacy (officially, at least) is now 80+% and extreme poverty is estimated to be less than 15%.   There are a number of great books on the constitution of India, but I will just list this set of  exceptional videos on the making of the constitution. Must watch! 

The Space & nuclear programs
This one is obvious and does not require much commentary. India's indigenous space program went from practically nothing to not just being a player in the international stage. Beyond the Moon and Mars missions, ISRO has had a huge impact on India's technological growth, societal evolution, scientific temperament, and of course as a source of immense pride.
Relatively speaking, I feel ISRO's impact is more significant to India than the American achievement of starting from scratch (well.. with German scientists) after WWII to putting a man on the moon in 1969 (which is one of the greatest chapters in American history). 

The same goes for India's nuclear program. On that note, I consider Homi Bhaba, Vikram Sarabhai and Satish Dhawan to be among India's greatest nation builders. As a starting point (on ISRO and the latter two men), I would recommend reading this nice book that details the evolution of the space program through the eyes of someone who was a part of it from the start.

The Telecom & IT revolution
As recently as the early 1980s, Indians had to wait years to get a telephone line. What happened after the the foundation of C-DOT (Center for the Development of Telematics) in 1985 is one of the awe-inspiring stories of Modern India. Whatever your political affiliation is, be thankful to Rajiv Gandhi & Sam Pitroda. Sam Pitroda's blog (read from bottom) is a great place to start. You don't have to take everything literally, but some facts are facts. His biography is also highly recommended.   This laid the foundation for the development of computing in India (Rajaraman's book is a treasure), and of course, India's Information Technology revolution. India employs 5 Million people in the IT sector, and IT exports are currently at $150 B (and still growing at a rapid pace).

The Green revolution (& the Dairy revolution)
The generally accepted version of the green revolution is that newly independent India was struggling with food production, had two famines and had made some policy blunders. Enter the Green revolution in the mid 60s headed by MS Swaminathan and American help, a switch was made to modern high-yield crops (mainly wheat) and agricultural production grew exponentially. 


Of course, the situation on the ground is more nuanced, and some revisionist takes  throw some shade on the true benefits. Nevertheless, India went from that struggle to being the second largest agricultural producer in the world. Roughly around the same time, India was milk deficient and used to import it! It is now the largest producer of milk (accounting for 20% of the world's production). Regardless of nuances and current issues, this was vital to a young, overpopulated country of half a billion mostly impoverished people.

The IITs  (& AIIMS, IIMs, etc)
India's contribution to science has always been immense, and pre-independence, there were small pockets of excellence (e.g. Indian Institute of Science, CV Raman). When the government set upon establishing the first 5 IITs, it was to develop technical excellence for the future of Indian industry and infrastructure.  Within a remarkably short time span (less than two decades, which is very short in academia), the goal of technical excellence was achieved, and quality of students graduating from the IITs was arguably "better" than the output of the top institutions anywhere in the world. Of course, while the rigor of the entrance exam and the extreme competition to get in ensured good inputs to the system, the institutions were also set up and run in a unique way. One can argue about the brain drain to the west, but the soft power created due to the global impact of IITians is significant. Similar - but less direct - things can be said about the very high quality talent pool and education in other national institutions of learning such as AIIMS & IIMs).

Most significant Tennis matches of the GOAT era

So here we are.. The GOAT candidates are still tied at 20 slams apiece. It is a futile endeavor to be objective about this kind of argument, but I would say that all 3 belong in the Top 5 of all time along with Laver and Borg. But if had to pick titles:

- Federer is the Greatest tennis player of all time for the way he waltzed his way to 20 slams, seemingly without breaking a sweat, for straddling 3 generations of players, and for setting the standard for his two competitors to match

- Djokovic is *clearly* the statistical GOAT (and the best career and has the best head-to-head records)

- Nadal is *clearly* the Clay GOAT

Also, in my opinion, here are the most significant matches between these 3 as far as GOAT arguments go

3. Nadal vs Djokovic, French Open 2021

 This is in 3rd place mainly because it is a semi-final and so it wasn't definitive for the winner. But if Nadal had won, he would've had a chance to establish a 3 slam lead over Djokovic, and would've stopped the two-time career grand slam for Djokovic. Instead, in a matter of a month, it was 20/20/20.

2. Nadal vs Federer, Australian Open 2017

   If Federer had not come back to win the last 5 games of the 5th set, 31 year old Rafa would have been just 2 slams behind Old man Fed. Rafa would've soon passed Federer's slam count and then had some gas left in the tank. Instead, Federer had a resurrection (and even beat Nadal 5 times in a row starting with that match)

1. Federer vs Djokovic, Wimbledon 2019.

    Undoubtedly, this is the one. Let's consider what would've happened if Federer had converted his match points in the 5th set: I don't think Djokovic would be capable of crossing Federer if he had lost that one (would've needed at least 7 more slams to do so) ; and a past-prime 38 year old would've demolished his greatest demons by coming back in the 5th set against his (40-15) tormentor and THE ultimate competitor who in his prime. 

Of course statistically speaking, any slam final between these three would have the same implications for the overall slam count, so here are some honorable mentions:

- Djokovic vs Nadal, French Open 2020 : Of course, vanquishing the clay GOAT in Roland Garros would be amazing, and the count would've been 20/19/18

- Federer vs Nadal, Wimbledon 2008 : Federer was untouchable on grass (in fact, untouchable on anything except clay), and Nadal was just a great Clay court player. This was the match that brought him into the discussion as a potential all time great.. .and of course, it is perhaps the greatest tennis match of all time.

COVID / India / May 28

The estimates and hot spots from last time appear to reflect the situation well, and it looks like India is past peak in deaths now.  The table below is updated. 

But here is the most important piece of info. Bhramar Mukherjee (Chair of Biostats @ UMich), a leading expert on the Indian COVID picture just released a preprint:

https://twitter.com/BhramarBioStat/status/1398413410719707138

Of course, many assumptions are made, and it is based on serosurveys, but this is about as good as it can get. Her estimate is that deaths are under-reported by a factor of 4.5 and cases are under-reported by a factor of 15.  That puts the deaths / Million at 1037, inching closer and closer to the US/UK/EU numbers. The peak in deaths might be of the same order. Again, all said and done, the India numbers might end up similar to US/UK/EU (factored by population).



Country   Cases/100k  |   Deaths/100k | Total deaths| 2nd/1st peak|  2nd/1st peak

California energy production

 This is a really cool website

http://www.caiso.com/TodaysOutlook/Pages/supply.html

Breaks down energy production by type. Renewables generated almost 90% of the total energy (during the day) yesterday, and Solar is doing particularly well! As I hinted here,  I am not sure that installing solar panels at home (in California) saves the earth.
