The start of India's space program

On the centenary birthday of Dr. Vikram Sarabhai, some remembrance of the beginnings of the Indian space program.

"Independent India was lucky to have Jawaharlal Nehru as its first Prime Minister, for he shared a common ideal with Bhabha and Sarabhai.  He believed that modern science and technology were indispensable to the development of the country......Bhabha, in the 1950s and 60s, was considered the czar of organized research in India and, more importantly, had Nehru's ear!  Thus, when Sarabhai, with Bhabha's support, came up with a space initiative for the country, Nehru said 'yes' even though  the country was passing through a very difficult phase both economically and politically.

"At that time India was facing severe economic and political hardships - there was a food shortage and that humiliating war in the north east.   Yet when Bhabha and Sarabhai came up with the space initiative, Nehru lent his wholehearted support.

"Given the background work of Dr Sarabhai and his co-workers at PRL and the expertise developed by Prof. Bernard Peters, Prof. M.G.K. Menon and their colleagues at the Tata Institute of Fundamental Research (TIFR), Bombay, who had flown a number of balloons from Hyderabad to carry out cosmic ray investigations,  Dr Homi Bhaba [sic] invited Dr Vikram Sarabhai to become a member of the Atomic Energy Commission and initiate space activity under the the umbrella of the Department of Atomic Energy.  Dr V. Sarabhai constituted the Indian National Committee for Space Research (INCOSPAR) with Prof. E.V. Chitnis, ...."

"When exactly Vikram came up with the notion of a space programme for India is not known.  R.G. Rastogi, his former student, claims to have heard him talk prophetically of setting up a rocket-launching programme 'by 1963' as far back as in the 1950s.  Praful Bhavsar, who had taken a leave of absence from PRL to do post-doctorate work at the University of Minnesota, recalls Vikram telling him something similar in 1959..."
"According to Rastogi, even Vikram's co-director at PRL, K.R. Ramanathan, was openly skeptical. 'He is too young, he has no idea how the government functions.  He will not get the money nor will establishment scientists allow it to happen.'...But Ramanathan had not counted on the chief weapon in Vikram's formidable arsenal of contacts: Homi J. Bhabha. 
It is tempting to speculate that Vikram and Bhabha, the two princes of Indian science, used their youthful days in Bangalore to spin up dreams for the future......It is tempting because of the uncanny sureness with which they set about their plans and their suggestion of complicity in so many of their actions. 
In August 1961, for instance, more than a year before the Chinese invasion and at a time when Nehru was still very much at the helm of the country's affairs, the union government, urged by Bhabha, identified an area known as 'space research and the peaceful uses of outer space' and placed it within the jurisdiction of the DAE.  As a part of the move, PRL was recognized as the 'appropriate centre' for research and development in space sciences.  And Vikram was co-opted into the board of the AEC.  More interestingly, in February 1962, the DAE created the Indian National Committee for Space Research (INCOSPAR) under Vikram's chairmanship to oversee all aspects of space research in the country.  Vikram had overcome the first seemingly impossible hurdle.

History and Modernity

Bernard Cohn (1928-2003) was a professor of anthropology at the University of Chicago who studied India extensively.  In his essay, "The Pasts of an Indian Village" (1961), Cohn examines the various pasts as remembered by the peoples of Senapur village in Uttar Pradesh, India.  The various groups, Thakurs, Chamars, Brahmins, Muslims and Telis, all have a different narrative regarding their  "legendary" past, as well as that of the past several generations.

Cohn goes on to note:

All Americans share a past created by our educational system and media of mass communication.  We can invoke this past and have it be meaningful across regional and class lines.  Indians do not as yet share such a past.  An appeal for action on the part of the central government, based on what is thought to be a universal identification with a traditional or historic past, is meaningless or leads to antagonistic reactions of major parts of the population...... 
I would speculate that a society is modern when it does have a past, when this past is shared by the vast majority of the society, and when it can be used on a national basis to determine and validate behavior. 
A shared history that can be used to determine and validate behavior.  I wonder if such exists even in that bastion of modernity, the United States of America, where there are many competing histories - of the Yankee North, of the Lost Cause South, of the African-Americans, of the Latinos, of the native Americans; and those of the various immigrant groups.   In terms of sheer numbers, perhaps the first two are the most important. 

But it was just a speculation on Cohn's part.

Harper’s Index: thermostat and test scores

https://harpers.org/archive/2019/08/harpers-index-august-2019/

Percentage change in women’s math test scores in a room that is between 80° and 90° F rather than 60° and 70° F : +27
In men’s math test scores : –7
Traced the source to:
Battle for the thermostat: Gender and the effect of temperature on cognitive performance

The math test in question was adding pairs of five digit numbers, 50 pairs in five minutes.
The verbal test was given the letters ADEHINRSTU, build as many (German) words as possible in 5 minutes.
"Our sample consisted exclusively out of students from universities in Berlin. The advantages of this subject pool is that they are relatively easy to recruit and homogenous in their cognitive skills. The disadvantage of this subject pool is that it is not representative of the whole population with respect to age and education level. 
About the results:
"Taken together, these results show that within a temperature range of 16 and 33 degrees Celsius, females generally exhibit better cognitive performance at the warmer end of the temperature distribution while men do better at colder temperatures. The increase in female cognitive performance appears to be driven largely by an increase in the number of submitted answers. We interpret this as evidence that the increased performance is driven in part by an increase in effort. Similarly, the decrease in male cognitive performance is partially driven by a decrease in observable effort. Importantly, the increase in female cognitive performance is larger and more precisely estimated than the decrease in male performance."
 What this result establishes, IMO, is that each person, or at least student in Berlin, tends to put forth most effort in a indoor temperature setting that suits them.   This may have some relevance to supposedly gender-neutral tests, the test setting may be important.

Stanislaus versus State of Madhya Pradesh - Historical Context

{Wiki}
Rev Stanislaus vs Madhya Pradesh, 1977 SCR (2) 611, is a matter where the Supreme Court of India considered the issue whether the fundamental right to practise and propagate religion includes the right to convert, held that the right to propagate does not include the right to convert and therefore upheld the constitutional validity of the laws enacted by Madhya Pradesh and Orissa legislatures prohibiting conversion by force, fraud or allurement.

Here is a timeline.

Religious Freedom and the Limits of Propagation: Conversion in the Constituent Assembly of India

Article: link (PDF)
Religious Freedom and the Limits of Propagation: Conversion in the Constituent Assembly of India
Sarah Claerhout and Jakob De Roover

Abstract:

In discussions about religious freedom in India, the country’s conflict regarding conversion plays a central role. The Constitution’s freedom of religion clause, Article 25, grants the right “freely to profess, practise and propagate religion,” but this has generated a dispute about the meaning of the right ‘to propagate’ and its relation to the freedom to convert. The recognition of this right is said to be the result of a key debate in the Constituent Assembly of India. To find out which ideas and arguments gave shape to this debate and the resulting religious freedom clause, we turn to the Assembly’s deliberations and come to a surprising conclusion: indeed, there was disagreement about conversion among the Assembly members, but this never took the form of a debate. Instead, there was a disconnect between the member’s concerns, objections, and comments concerning the draft article on the one hand, and the Assembly’s decision about the religious freedom clause on the other. If a key ‘debate’ took this form, what then could the ongoing dispute concerning conversion in India be about? We first examine some recent historiographical accounts of the Indian conflicts about conversion and proselytization. Then we develop a hypothesis that aims to make sense of this enduring conflict by identifying a blindness at its core: people reasoning against the background of Indian traditions see ‘propagation of religion’ as the human dissemination of tradition; this is incompatible with a religious conception where conversion and propagation of faith are seen in terms of God’s intervention. These two ways of seeing ‘propagation’ generate two conflicting experiences of the Indian dispute about religious freedom and conversion.

If for nothing else,  the glimpses of actual debates in the Indian Constituent Assembly are a reason to read this paper.

Count of generations

If I take my maternal grandparents as generation 0, then already my family has generation 3 and generation 4 family members who are the same age (actually some generation 4 who are older by a few years than generation 3).

Is this just an anomaly of the modern age with extended maternal and child survival compared to the norm over 100K years of human existence? 

When geneticists try to estimate generation counts over aeons, I wonder what models they use.

More on Indian secularism

Readers here should have noticed a peculiar situation.  Here I am, advocating SNB's position that India never produced a religion, and on the other hand, I do talk about Indian secularism, secularism and its failures in the Indian Constitution, etc., as though there is a Hindu religion. 

The problem is that we must hold two inconsistent sets of ideas in our mind - one to deal with India as it is today, with the language of "religion" and the current set of Constitutional laws; and the other to deal with India as it should be, if SNB's intellectual revolution ever catches fire.  In that mode, there is no Hinduism religion that needs to be accorded any freedom of religion, but something quite different; and we have to invent the mechanism that this collection of entities that goes under the name of Hinduism lives with the imported religions in India.

Of course, it may be true that too much water has flowed down the Ganga, and that Hindus can't now ever overthrow their religion and be this something else.

Anyway, SNB and Jakob de Roover spell out the consequences of the Hindu traditions being interpreted as a religion in this long, but don't tl;dr read.

"Bob Wimmer is a scientist at the University of Kiel in Germany who built a radiation detector for Chang'e 4 {China's lunar lander on the far side of the moon}.  He says the speed at which the Chinese work is astonishing.
"European missions are extremely slow, the Americans are about twice as fast, and the Chinese are a factor of two to five faster than the Americans."
From the moment he got funding to the moment his experiment launched, was just over a year, which is nothing for a space mission.

In India, a Hindu wife cannot inherit from a Muslim husband

When, in India, a Hindu woman marries a Muslim man,

the marriage of a Hindu female with a Muslim male is not a regular or valid (sahih) marriage, but merely an irregular (fasid) marriage.
Thus has the Supreme Court of India ruled, January 22 of this year.  The Court further notes that "the legal effect of a fasid marriage is that" the wife "is not entitled to inherit the properties of the husband".

The Supreme Court judgement is available here (Google Drive Link, hope it works).

The only proponents for the Uniform Civil Code that the Directive Principles of the Indian Constitution call for, are the so-called Hindu nationalists.   The so-called secularists don't want to fix these kinds of problems.

PS: Until this problem is fixed, anyone who finds inter-religious marriages of Hindu women with Muslim men to be acceptable has to be termed as a anti-Hindu misogynist.

A mild symptom of an old pattern

Amy Zegart wrote in The Atlantic:

Decades of Being Wrong About China Should Teach Us Something
American analysts keep trying to fit the country into familiar patterns—ignoring the many ways in which it’s an exception.


The underlying mistake is the assumption that Europe represents the norm and that the rest of the world recapitulates European history.

Eye opener

When I read this below more than ten years ago, it opened up a perspective that was totally new to me. Its author, Dr. Thomas A. Marks taught at the Army War College.

Citation:
Thomas A. Marks (2004) India: State Response to Insurgency in Jammu & Kashmir – The Jammu Case, Low Intensity Conflict & Law Enforcement, 12:3, 122-143, DOI: 10.1080/09662840500072615

Indeed, the internal war in J{ammu}&K{Kashmir}, when scaled, does not begin to approach the levels of criminal violence present in those U.S. metropolitan areas best known for their murder rates. The ‘death count’ in Jammu & Kashmir for 2003 stood at 836 civilians, 1447 militants and 380 security personnel. If this violence is aggregated (2,663), which is unorthodox but certainly presents the worst possible statistical picture, it scales out at 24.5:100,000 population. This would place J&K between Memphis (24.7:100,000) and Chicago (22.2:100,000), in the 2002 murder rankings when examining American cities with populations greater than 500,000, well off the pace established by the likes of Washington, DC (45.8:100,000) or Detroit (42.0:100,000).

She provided it to me in response to my question,  "how does one jump from "such and such are problems with Hindus" to "the cause of these problems is lack of monotheism"?"

She writes: "The thesis is a bit dated, I would perhaps make the same arguments in a more measured way now. But the core of the problem with reform discourse and the problem in general of 19th century social reform in India has been looked at in a fairly consistent, systematic and coherent way."

"Eukaryogenesis, how special really?"

Eukaryogenesis, how special really?

Another interesting article.

Abstract

Eukaryogenesis is widely viewed as an improbable evolutionary transition uniquely affecting the evolution of life on this planet. However, scientific and popular rhetoric extolling this event as a singularity lacks rigorous evidential and statistical support. Here, we question several of the usual claims about the specialness of eukaryogenesis, focusing on both eukaryogenesis as a process and its outcome, the eukaryotic cell. We argue in favor of four ideas. 

  • First, the criteria by which we judge eukaryogenesis to have required a genuinely unlikely series of events 2 billion years in the making are being eroded by discoveries that fill in the gaps of the prokaryote:eukaryote “discontinuity.”
  • Second, eukaryogenesis confronts evolutionary theory in ways not different from other evolutionary transitions in individuality; parallel systems can be found at several hierarchical levels.
  • Third, identifying which of several complex cellular features confer on eukaryotes a putative richer evolutionary potential remains an area of speculation: various keys to success have been proposed and rejected over the five-decade history of research in this area.
  • Fourth, and perhaps most importantly, it is difficult and may be impossible to eliminate eukaryocentric bias from the measures by which eukaryotes as a whole are judged to have achieved greater success than prokaryotes as a whole. 

Overall, we question whether premises of existing theories about the uniqueness of eukaryogenesis and the greater evolutionary potential of eukaryotes have been objectively formulated and whether, despite widespread acceptance that eukaryogenesis was “special,” any such notion has more than rhetorical value.

Context: reading of David Quammen's "The Tangled Tree: A Radical New History of Life".

Peak Gene

Interesting article.

We have reached peak gene, and passed it.
Ken Richardson in "It's The End Of The Gene As We Know It" 

In scientific, as well as popular descriptions today, genes “act,” “behave,” “direct,” “control,” “design,” “influence,” have “effects,” are “responsible for,” are “selfish,” and so on, as if minds of their own with designs and intentions.

But at the same time, a counter-narrative is building, not from the media but from inside science itself.... Scientists now understand that the information in the DNA code can only serve as a template for a protein. It cannot possibly serve as instructions for the more complex task of putting the proteins together into a fully functioning being, no more than the characters on a typewriter can produce a story.
...
First, laboratory experiments have shown how living forms probably flourished as “molecular soups” long before genes existed. They self-organized, synthesized polymers (like RNA and DNA), adapted, and reproduced through interactions among hundreds of components. That means they followed “instructions” arising from relations between components, according to current conditions, with no overall controller: compositional information, as the geneticist Doron Lancet calls it.
In this perspective, the genes evolved later, as products of prior systems, not as the original designers and controllers of them. More likely as templates for components as and when needed: a kind of facility for “just in time” supply of parts needed on a recurring basis.
...
We have traditionally thought of cell contents as servants to the DNA instructions. But, as the British biologist Denis Noble insists in an interview with the writer Suzan Mazur, “The modern synthesis has got causality in biology wrong … DNA on its own does absolutely nothing until activated by the rest of the system … DNA is not a cause in an active sense. I think it is better described as a passive data base which is used by the organism to enable it to make the proteins that it requires.”

PS: the proposed definition of "gene" by Portin and Wilkins:
A gene is a DNA sequence (whose component segments do not necessarily need to be physically contiguous) that specifies one or more sequence-related RNAs/proteins that are both evoked by Genetic Regulatory Networks and participate as elements in Genetic Regulatory Networks, often with indirect effects, or as outputs of Genetic Regulatory Networks, the latter yielding more direct phenotypic effects.
Wiki tells us: genetic regulatory network (GRN) is a collection of molecular regulators that interact with each other and with other substances in the cell to govern the gene expressionlevels of mRNA and proteins.

Arya per Sita in the Ramayana



Dholavira Seal from the Harappan Era.  No implication that this is connected to the story below. I just like it as an illustration.


 Aravindan Neelakandan reminds us:

In Ramayana, the Rakshasas are a group of people who were not, as many consider, uncultured, demonic people. Rather, they considered themselves superior to other humans and animals. In fact, when Ravana asked for the boon of invincibility from the creator Deity, he left out humans and animals because he thought they were too inferior to be bothered about.

The Rakshasa women who guarded Sita when she was being held captive were instructed by Ravana to torment Sita endlessly. Their taunts and threats even led Sita to contemplate suicide. But for the timely intelligent intervention of Hanuman - a Vanara emissary from Rama, she would have succumbed to the thought of suicide.

Now Rama had vanquished Ravana with the help of the Vanaras - the monkeys or the non-human primates. Hanuman was here to tell Sita the good news. Then he looked at all those Rakshasa women who had tormented her. He asked her permission to punish them.

Sita refused him to give permission but then told Hanuman what a bear once told a tiger.

This story told by Sita is known throughout India for millennia now . It is about how a hunter chased by a tiger in a forest, escaped by climbing a tall tree. In the tree was a bear. The tiger told the bear that the hunter is the killer of wild animals and hence the bear should push him down. The bear refused. He said that the tree being the home of the bear, the hunter had become its guest. And it was the dharma of the householder to protect the guest.
The tiger waited. Soon, the bear fell asleep. The tiger told the man that despite the grand words, the bear was actually reserving the man for himself. So, the tiger suggested that if the man pushed the bear down, then the tiger could easily devour and eat the sleepy bear and would go its way while the man too could be free of danger. The hunter yielded to the temptation and pushed the bear down. The bear, adept in living on the trees, saved itself.

Now the tiger appealed again to the bear. Pointing out the treachery of the man it asked him to push him down. The bear told the tiger that a noble person does not do evil deeds to revenge evil deeds. A good person, he said, always does good deeds irrespective of what the others do. After saying this, Sita defined the term ‘Arya’ in a very famous statement:

Kaaryam kaarunyamaaryen na kashchit naaparaadhyati
(कार्यं कारुण्यमार्येण न कश्चिन्नापराध्यति) :
Showing kindness (towards the saintly and the sinner alike) defines a person as Arya for there is none who has never committed a wrong.

Valmiki Ramayana: Yuddha Kanda: 46

Here, the term ‘Arya’, much maligned by colonial Indology, European historiography and Nazi racism , is defined as a quality that is even above mercy, compassion and empathy combined, possessed not only by humans but by all living beings. Only a being who possesses that quality irrespective of what species it belongs to, should be considered as noble - ‘Arya’. Thus defined Sita the term ‘Arya’.

India - a growing discontent?

There is an outfit that publishes the World Happiness Report.  The primary measure is the "Cantril Life Ladder" (from Hadley Cantril, Patterns of Human Concern, 1965).

As far as I can tell, some 1000-odd people of age 15+  in each of 156 to 158 countries are asked by Gallup polling each year the following question, which in English reads:
“Please imagine a ladder, with steps numbered from 0 at the bottom to 10 at the top. The top of the ladder represents the best possible life for you and the bottom of the ladder represents the worst possible life for you. On which step of the ladder would you say you personally feel you stand at this time?”
The average for the country is supposed to reflect its level of happiness.   The Cantril Life Ladder is available for India from 2006 onwards.  The report also includes measures that one might think affects the answers given on the Cantril Life Ladder, such as per capita income and life expectancy, and survey measures such as perceived freedom to make life choices, perceived corruption, and so on.  India is generally improving on these measures over the 2006-2018 time period.  One interesting thing is that countries with poorer improvement on these measures can be happier than India.

On Graduate School

For a graduate student it can be very difficult. It’s very easy to get discouraged if you have no real understanding that you’re going to be stuck for a very long time.

I could very easily have imagined myself getting discouraged and dropping out of graduate school. That could have easily happened to me under different circumstances.

Graduate school is a different environment and then you start to wonder—“Am I really good enough to do research-level math?” It’s hard, in fact, to tell. You see all these people who are doing great things around you and then you think, well, maybe you’re not cut out for this. So I think it’s important [long pause] to have someone who believes in you.

Wincing at the state of physics

High energy particle physics theorists - the people who lead the investigations into the most fundamental aspects of nature - have been having a bad streak.  They have had no major successful new idea in the last forty years, all the theories they've proposed -- and there are lots of them -- have failed to yield an experimental signature.  The excuses for failure are flying thick.

Mathematician Peter Woit at Columbia University in his blog, recently quoted physicist Nima Arkani-Hamed of the Institute of Advanced Studies, Princeton, from an answer given in the Q&A session after a seminar, thus:
You could very justifiably say “look, you’re just continuing to make excuses for a paradigm that failed”, OK, and I would say that’s true, and even the paradigm most of your advisors love [e.g. usual SUSY] was already an excuse for the failure of non-supersymmetric GUTs before that.
That is a perfectly decent attitude to take, but I would like to at least tell you that you should study some of the history of physics. This very, very, very rarely happens, that some idea that seems basically right is just crap and wrong, It’s probably mostly right with a tweak or some reinterpretation. You’d have to go back over…, I don’t know how far you’d have to go back, even Ptolemy wasn’t so far from wrong
Ouch! That is some seriously bad reading of the history of physics.   That was amply pointed out in the comments on the blog.

Rutgers University physicist  Amitabh Lath rightly, I think, pointed out:
Stop picking on Nima. You all are doing the internet thing of taking one statement in an hour talk and ganging up.
But challenged on it, he continued:
Even the pre-Copernican Ptolemaic stuff made sense to me. Basically, there are concepts in a failed theory that you might want to keep (things moving in circles around other things) and others you might want to jettison. Granted, he is not very good at history of science.
 Double Ouch!  Is "things moving in circles around other things" a valuable idea from the Ptolemaic theory of the solar system?  I think it is wrong on two counts -- firstly, the idea of things moving in circles around other things is present in earlier theories of the heavens; and secondly, things moving in circles around other things is not a theoretical idea; it is a root observation, the experience early humans had of the skies, at the very start of the study of the heavens.   For example, the sun rises at the east horizon in the morning every day, sets at the west horizon in the evening  and presumably somehow finds its way back in the dark to the east horizon the next morning, completing a closed loop if not a circle, per the early earth-bound humans.

I'm happy that I'm not in the high energy physics milieu at all.  Lot of mathematics, very little understanding.

American obsession with IQ - v3

Binet Betrayed

Here's the way Scott Barry Kaufman tells the story of Alfred Binet, the inventor of the modern IQ test.

As the nineteenth century came to an end, business and civic leaders across a number of West European and North American countries united to promote compulsory universal public education.  But this posed a serious problem: how should a diverse population of children be educated?
....
The opportunity of a lifetime {for Binet} came in October 1904, when Joseph Chaumie, the {French} minister of public instruciton, established a commission to create a way to identify students in need of alternative education.....Binet and {Theodore} Simon immediately went to work.
....
Binet and Simon made clear the purpose of their test:

Our purpose is to be able to measure the intellectual capacity of a child who is brought to us in order to know whether he is normal or retarded.  We should, therefore, study his condition at that time and that time only.   We have nothing to do either with his past history or his future; consequently we shall neglect his etiology, and we shall make no attempt to distinguish between acquired and congenital idiocy...we do not attempt to establish or prepare a prognosis and we leave unanswered the question of whether this retardation is curable, or even improbable.   We shall limit ourselves to ascertaining the truth about his present mental state.
....
Along with their test, they also published a number of caveats.  First, they made it clear that their test does not measure a person's absolute level of intelligence.   They warned that their test couldn't possibly offer precise measurement like inches as measured by a ruler.   Instead, a score on their test was simply a classification entirely relative to that of other children of the same age. ....
....
Binet and Simon also acknowledged that many others than intellectual ability could influence performance on their tests, such as the unnaturalness of the testing situation and the potential for the test to intimidate children.   They also mentioned longer term influences, such as background, upbringing, health and effort.   Due to these other potential influences, they stressed the need to compare any person's test results only with those of comparable backgrounds.  Finally, they noted the importance of constant retesting, pointing out that individuals' intellectual development progresses at variable rates, due to different rates of maturation as well as differences in intellectual experiences.
....
It's noteworthy that the Binet-Simon scale never yielded an intelligence quotient (IQ).  In fact, long after Binet's death, Simon indicated that the use of a summary IQ score was a betrayal of the purpose of their test.  While Binet and Simon's purpose was noble, let's be absolutely clear: most people in France just wanted to weed out the intellectually disabled os that the "normal" students would not be slowed down.
....
Alas, Binet's efforts, caveats and cautions were almost completely ignored by the French establishment...Binet and Simon's efforts were wasted in their native France.  Binet personally felt as though he was a failure.

Soon his test would spread like wildfire across the globe-- particularly in America-- and to his horror, his test was used for purposes he never intended.   Toward the very end of his life, in response to statements that children with low test scores would never achieve certain things, he wrote in exasperation: "Never! What a strong word!  A few modern philosphers seem to lend their moral support to the these deplorable verdicts when they assert that an individual's intelligence is a fixed quantity, a quantity which cannot be increased.   We must protest and react against this brutal pessimism.  We shall attempt to prove that it is without foundation... With practice, training , and above all method, we manage to increase our attention, our memory, our judgment and literally to become more intelligent than we were before."

Binet even developed various "mental orthopedics" -- intellectual exercises -- to show the potential for remediation.  But it was too late.  On October 28, 1911, Binet suffered a stroke and passed away at the young age of 54.   The mass testing movement in America had just begun, with the testing proponents carrying with them a completely different conceptualization of human intelligence.

American obsession with IQ v2

Book-ends:  Perhaps it is karma that a nation obsessed with IQ finally got a President that it deserves - self-proclaimed, not simply smart, "but genius....and a very stable genius at that!"
When our intelligence scales have become more accurate and the laws governing IQ changes have been more definitively established it will then be possible to say that there is nothing about an individual as important as his IQ, except possibly his morals; that the greatest educational problem is to determine the kind of education best suited to each IQ level; that the first concern of a nation should be the average IQ of its citizens, and the eugenic and dysgenic influences which are capable of raising or lowering that level; that the great test problem of democracy is how to adjust itself to the large IQ differences which can be demonstrated to exist among the members of any race or nationality group.  — Lewis M. Terman (1922)
"Sorry losers and haters, but my I.Q. is one of the highest -and you all know it! Please don't feel so stupid or insecure,it's not your fault" (Donald J. Trump, May 8, 2013)

Take that, you libtard!
I hate the impudence of a claim that in fifty minutes you can judge and classify a human being’s predestined fitness in life. I hate the pretentiousness of that claim. I hate the abuse of scientific method which it involves. I hate the sense of superiority which it creates, and the sense of inferiority which it imposes. Walter Lippmann (1923)

Some definitions of intelligence

Scott Barry Kaufman, in "Ungifted: Intelligence Redefined" has a graphic itself based on J.D. Wasserman "A History of Intelligence Assessment: The Unfinished Tapestry", which is available online. 

Some few tie intelligence to adaptability.  Definitions below the fold.

Genes and IQ

The Scientific American reports a new idea on what triggers Alzheimer's.

This paragraph triggered me, however:

But at start of the 21st century, researchers uncovered a harbinger for GR {gene recombination}. We discovered that DNA sequences vary from cell to cell, meaning that our brains are a vast mosaic of distinct genomes, a phenomenon aptly referred to as “genomic mosaicism.” These changes are distinct from epigenetic changes that do not directly affect DNA sequences. Scientists have now identified multiple sequence changes that are quite varied and seemingly random, consisting—in order of decreasing size—of entire chromosomes (aneuploidies), smaller copy number variations, even smaller LINE1 retrotransposon repeat elements and “single nucleotide variations that alter individual nucleotides.
How genes determine IQ becomes a bit mysterious if "our brains are a vast mosaic of distinct genomes".   One question presumably would be that are these "vast mosaic of distinct genomes in the brain" the same in some statistical sense in identical twins raised together and those raised separately?

America's obsession

Scott Barry Kaufman notes that when David Wechsler came up with his tests (for the Wechsler-Bellevue Intelligence Scale) around 1939,

"The test publishers were skeptical.  Why take so much time to measure a person's intelligence? This was antithetical to America's obsession with a fast, cheap and efficient way to categorize the totality of a person".
 This leads to the question, why is America so obsessed?  Is it a by-product of the ideology of capitalism?

Scott Barry Kaufman defies his IQ score

This article in The Atlantic, 2013, titled "The Perils of Giving Kids IQ Tests" doesn't say that IQ testing is useless.

We classify learning disabilities because children with dyslexia require very different academic support than children with Asperger's. In order to help these very different children, we must identify and understand their deficits and the resources those children will need. I have sat in on many meetings in which we - teams of psychologists, teachers, parents, learning specialists, and administrators - work to find the ideal combination of resources for kids with learning challenges. I have even recommended intelligence testing for students who, despite their persistence, diligence and effort, are not succeeding in school. I've seen testing lead to real academic and cognitive improvement, thanks to individualized education plans and access to learning resource professionals.
But the article does say that IQ test results are not destiny, via the story of Scott Barry Kaufman.
Kaufman, writing of his experience in Ungifted: Intelligence Redefined. The Truth About Talent, Practice, Creativity, and the Many Paths to Greatness, may have thought he knew what was at stake when he visited that school psychologist for testing, but he would not fully grasp the influence that afternoon of testing would have on the trajectory of his life until much later. The psychologist who tested Kaufman concluded that he had a relatively low IQ, a score low enough to earn him the label "seriously learning disabled."
Kaufman narrates:
After school I dash off to the local library and find a book about human intelligence. I flip through the pages and come face to face with a terrifying chart. At the top is listed the average IQ of PhDs. I am way lower than that number. Tentatively, I go down the list. College graduate? Closer, but still no cigar. My blood pressure is rising. Semiskilled laborer? In my dreams. After some time, I finally find my range: "Lucky to graduate high school," it says.
 But Kaufman "ripped up his label, held on tight to his growth mindset and his well-honed skills of grit, diligence, and persistence, and rode that potential all the way to a Ph.D from Yale."

So that makes three - Feynman,  Boyd and Kaufman.  But how many children have fallen victim to IQ humbug?

PS:

Q: So the analogy suggests that IQ scores are...?
A: A proxy for the skills and habits encouraged by a bureaucratic society; skills and habits which can be at once highly heritable (because of strong transmission through family and neighbors) and highly learned (within the scope of what it is biologically possible for humans to learn and internalize). Innate ability needn't enter into it at all. The implications for democracy would be nearly nil.
Q: And the famous g?
A: Is a statistical artifact, or better yet a myth; but that is another story for another time.

Nassim Nicholas Taleb tweets about IQ

The twitter thread is here.  Please refer to the thread on twitter for full detail.

FYI: IYI = The IYI class: Intellectual-Yet-Idiot
One of the key take aways: "the only robust measure of "rationality" & "intelligence" is survival, avoidance of ruin/left tail/absorbing barrier, (ergodicity). Nothing that does not account for ability to survive counts as a measure of "intelligence".

Sorry for the poor formatting.  Will try to fix.

PS: Also found this:

“I suspect the I.Q., SAT, and school grades are tests designed by nerds so they can get high scores in order to call each other intelligent...Smart and wise people who score low on IQ tests, or patently intellectually defective ones, like the former U.S. president George
W. Bush, who score high on them (130), are testing the test and not the reverse.”

― Nassim Nicholas Taleb, The Bed of Procrustes: Philosophical and Practical Aphorisms


"IQ" THREAD

"IQ" measures an inferior form of intelligence, stripped of 2nd order effects, meant to select paper shufflers, obedient IYIs.

IQ humbug

The weekly email from "Learning How to Learn" contained this:

Book of the Year
Our very favorite, most highly recommended book this year is Boyd: The Fighter Pilot Who Changed the Art of War. This book ranks among our favorite biographies ever. Boyd was a genius level iconoclast (with a measured IQ of 90), and a rebel of the first order, who changed the military’s approach to war and saved countless lives while he was at it. Boyd took on idiocy where ever he found it, whether with bombastic Pentagon generals who were happy to fake important tests, or those who thought they could outgun him in the air. Boyd was so witty, engaging, and fearless in tackling new approaches, and the research behind this extraordinary biography is so artfully done, that it’s a “can’t miss” book for anyone who loves rebels and reading. OODA away!
The highlighted phrase caught my eye.  Wiki has an extensive article on Boyd; but (without reading the book), the best I can do is from a review of this book:

Coram pushes on quickly through Boyd's early school years, covering seemingly inconsequential tidbits such as Boyd's being gifted in math but being pegged with an IQ of only 90. Although the test was suspect, Boyd refused to retake the test and later Boyd used this score to humiliate those who challenged him in a battle of wits.

Green news - electric cars in China

Per John Cassidy in the New Yorker: in China

Under a new quota system that will go into effect next year, ten per cent of an automaker’s sales in what is now the world’s biggest car market have to be plug-in vehicles. In 2020, the figure will be raised to twelve per cent. By 2025, according to some estimates, electric vehicles could account for a fifth of all the sales in China.

QOTD


Via dailykos:

Emmanuel Macron has used the first world war armistice centenary commemorations to call for a “real” European army, warning that rising nationalism and populism threaten the fragile peace on the continent.

“We have to protect ourselves with respect to China, Russia and even the United States of America,” Macron said as he visited the sites of the western front battlefields in northern France on Tuesday.
