The question of whether a computer should be used in teaching and
learning, is no more interesting than the question whether a book
should be used for reading.
The interesting question is of how to use the computer to teach and
learn, and how not to use it to teach and learn.

Love, personal qualities and infection
She said: “It seems to me that everyone has a quality that can get the better of love. Is stronger, you see. Like pride. Or honesty. Or moral – even intellectual, even emotional – integrity. Take two people in love. The only thing that can really upset things is this personal quality in one of them. Other people don’t come into it at all. Except in a roundabout way – as intruments of jealousy, for instance. Don’t you agree?”
I wasn’t sure about anything, but I said yes.
“Another thing about love,” the girl with ringlets said, “is its extraordinary infection. Has it ever occured to you that when you’re in love with someone you’re really wanting to be loved yourself? Because that, of course is the natural law. I mean, it would be odd if every time one person loved another person the first person wasn’t loved in return. There’s only a very tiny percentage of that kind of thing.”

Free Press and Democracy
A free press is an essential part of a democratic system. In a society like ours, with its stark inequalities, only a media free of government and corporate pressures can ensure that the voiceless are heard. What we are seeing currently is not just blatant collusion between the media and big business but also a deliberate obliteration of much of what happens to the millions who live on the margins.
via Economic and Political Weekly
This is what Media Lens has to say about the BBC which is supposed to be in public interest and impartial.
Instead of providing responsible, public-service journalism, the BBC acts as a conduit for government propaganda. It is particularly noxious that the organisation relentlessly channels the state’s supposedly benign intentions abroad. This is the diet of daily bias and distortion we are all fed. When will BBC heads roll for that?
But isn’t this true of the media in India also? Or elsewhere in the world for that matter. Tehelka reports that many of the barons of power also control the local media in newly formed state of Chattisgad. And what is the use of controlling media when they are not used for gains. When the so called free media becomes a part of the political parties we cannot be sure of what they report.
If the Congress has Naveen Jindal, the BJP has Ajay Sancheti. If the Congress has the Lokmat, the BJP has the Hari Bhoomi. Barring coal, in which both the Centre and the states had their hands in the till, in the case of other mineral resources, the real corruption lies in the states.
It is not that people do not use media for their own gain, media is used for spreading ideology, there are many mouthpiece outlets for political parties and others which propagate the ideas. But what is worst is that the masquerade that many media houses put on themselves claiming to be honest and working in public interest, and people at large believe them, being obliviousto the fact that these very media houses are the ones who are power brokers and very much in the filth as corporates and politicians. A recent example of this was the Radia tapes.
The complete blackout of the Niira Radia tapes by the entire broadcast media and most of the major English newspapers paints a truer picture of corruption in the country than the talk shows in the various news channels and the breast-beating in all the newspapers about the 2G, CWG, Adarsh, and other scams.

It was not until the non-main-stream media began to show up too much, there was some coverage given. But the very fact that the accused are in complete denial of what happened is what is disturbing. We usually held names like Barkha Dutt, Vir Sanghvi well but these tapes just show how much they are in the filth of what they pretend to expose. From then on, I have given up on NDTV as a reliable source, which earlier I thought it was. But then what do you trust?
At the same time, it is worth noting that neither Barkha nor any of the other journalists whose names have come up have denied that those conversations took place. So why not let the reader or TV viewer read or listen to the transcripts and decide whether Dutt and Sanghvi’s conversations with Radia are a part of “normal journalistic duties” or amount to pimping for politicians and business houses? Or perhaps they were doing social service for the Congress? Play the tapes on your show, na, Ms Dutt, instead of tweeting about them? Why not let ‘We, The People’ decide, instead of you deciding for us all?
via|G. Sampath – DNA
The media blackout of particular events is what I find disturbing. What it shows the kind of camaraderie that exists between different media houses and their corporate and political cronies. That basically means that the news, sorry the Breaking News that you see is like a managed play, with directors and writers deciding what people see, hear and think. In Marathi novel (Ithink it was Swami (स्वामी) by Ranjit Desai) I had read a sentence which fits these situations well, it reads:
मी मारल्या सारखे करतो, तु रडल्या सारखे कर.
( I will feign to hit, you feign to cry.)
This creates an illusion about real problems. Most of the News channels that are beamed in India follow this line. Put all the focus on some non-issues, or twist them from certain angles so that why all this happens remains oblivious to the viewers. If our media was after all serious about the issues that they present, they would have seen to it that things are done.
Many a times what I have also found reading reports on various different news services is that they are same. I mean many a times they are word to word same, as if the reports have been written at one place and distributed. I do not have links right now, but will update this post when I do. This again creates a picture that what news we see is heavily filtered, and sometimes flavours are added to create sensationalism. And the icing is that we all think this is genuine, with “Free Press in A Democracy”. Orwell had a foresight about this as well:
Of course, print will continue to be used, and it is interesting to speculate what kinds of reading matter would survive in a rigidly totalitarian society. Newspapers will presumably continue until television technique reaches a higher level, but apart from newspapers it is doubtful even now whether the great mass of people in the industrialized countries feel the need for any kind of literature. They are unwilling, at any rate, to spend anywhere near as much on reading matter as they spend on several other recreations. Probably novels and stories will be completely superseded by film and radio productions. Or perhaps some kind of low grade sensational fiction will survive, produced by a sort of conveyor-belt process that reduces human initiative to the minimum.
via The Prevention of Literature | George Orwell
The only reason I see that India is feudal and corrupt is that the so called Free Press was never able to take up the challenge to the nexus, and ultimately now has become a part of it.
In our age, the idea of intellectual liberty is under attack from two directions. On the one side are its theoretical enemies, the apologists of totalitarianism, and on the other its immediate, practical enemies, monopoly and bureaucracy.
via The Prevention of Literature | George Orwell
Though there are dissidents here and there, this now has become global phenomena, with the Indian media people just following the suit. And if this is the case, what difference does it make whether you are living in a democracy or a totalitarian state?
And Orwell wraps it up thus:
A totalitarian society which succeeded in perpetuating itself would probably set up a schizophrenic system of thought, in which the laws of common sense held good in everyday life and in certain exact sciences, but could be disregarded by the politician, the historian, and the sociologist. Already there are countless people who would think it scandalous to falsify a scientific textbook, but would see nothing wrong in falsifying an historical fact. It is at the point where literature and politics cross that totalitarianism exerts its greatest pressure on the intellectual.

Reason and Faith – Misconceptions in Science Education
Reason does not work in matters of faith. But it may have a chance at clearing misconceptions.
via Tehelka
Truly so. In case of my field of study, namely science education research, it may be the other way round. The classic studies in science education aim at identifying the misconceptions that the learners have regarding a particular subject and then finding a mechanism by which they could be addressed.
This was a very simple but very basic presentation of what most studies try to achieve, though the methodology may be different. There are some studies which present us with a conceptual framework so that all the responses and the problems with the learners can be seen in light of a theoretical construct. This they say will enable us to make sense of what we see in the classrooms, and what is present as representation in the learners mind. What I think they are trying to say is that we need to get to the conceptual structures that lead to formation of the misconceptions.
Now mind you that many of these misconceptions in science are very stubborn and people are very reluctant to give them up. The reason may be that many of these misconceptions come from direct factual experience in the real world. And from what I know about Philosophy of Science, we might want to make a case that all science is counter-intuitive to our everyday experience. This would explain why misconceptions in science arise. But would this case explain all the known misconceptions?
Let us do some analysis of how a particular misconception might arise.There can be two different reasons for a misconception to arise, if we adhere to deductive logic. That is to say we assume that we have a set of starting statements that are given, whose authenticity is not questioned. And from these set of statements we make certain deductions regarding the world out there. Now there can be two problems with this scenario, one is that the set of statements that we are taking for granted might be wrong, the other is that in the process of deduction that we have followed we made a mistake. The mistake is learnt only when the end result of our analysis is not consistent with the observations in the real world. Or it might be even the case that the so called misconception will lead to a correct answer, at least in some cases. In these cases we have to resort to more detailed analysis of the thought structure which lead to the answers. Another identifying characteristic of the misconceptions is presence of the inconsistencies across different areas known to the learners. Whereas they might get a particular concept clearly and correctly, in applying same thing for another concept they just might revert to a completely opposite argument and in doing this they do not realise the inconsistency.
We will be clearer on this issue when we talk with a few examples. Suppose that we have a scenario in which we are trying to understand the phenomena of day and night, its causes and consequences. A typical argument in our class goes like this:
How many have seen the Sun set?
Almost all hands would go up, then comes the next question:
How many have seen the Sun rise?
Almost same number of hands go up, excepting a few, who are late risers like me. Some of the more intelligent and the more knowledgeable would say,
“Wait! Sun doesn’t rise and set, it is the Earth that is moving, so it causes the apparent motion of Sun across the sky, the start and end of which we call as day and night. So in conclusion the Sun doesn’t rise and set, it is an illusion created by motion of Earth.”
To this all of the class agrees. This is what they have learned in the text-book, and mind you the text-book represents truth and only truth, nothing else. It is there to dispel your doubts and misconceptions and is made by a committee of experts who are highly knowledgeable about these things. Now let us continue this line of reasoning and ask them the next question in this series.
Does the Moon rise? If so, does it rise everyday?
The responses to this question are mixed. Most of them would say that it does not rise, it is always there, up in the sky. Some would gather courage and say that it does rise.
Does the Moon set?
Again to this the response is mixed, and mostly negative. Most of them are adamant about the ever presence of the moon in the sky. The next question really upsets them
Do the stars rise and set?
Now this question definitely gets a negative response from almost all of them. Even the more knowledgeable ones fall. They have read different parts of the story, but have not connected them. They tell you the following: “No the stars do not move, they are there all the time.” They also tell you that there is something called as the fixed stars and this is in the text-book, which cannot be wrong. And when asked:
Why are we not able to see the stars during the day time?
They tell you “Of course you cannot see the stars during the day time. This is because our Sun, which is also a star, is too bright and the other stars too far away and hence are dim. So our Sun’s brightness, overwhelms the other stars, and hence they are not visible during the day time, but they are there nonetheless. In the night time, since the Sun is no longer visible, the stars become visible. Have you never noticed that during the evening twilight the stars become visible one by one, the brighter ones first. Whereas in the morning the brightest are the last ones to disappear.”
Of course, the things said above and the reasoning given sounds good. So much so that the respondents are convinced that they understand how things work, and have an elaborate reasoning mechanism to explain the observed things, in this case the formation of day and night and appearance / disappearance of stars during night and day respectively.
You ask them:
Don’t you think there is a problem with what you have just said?
“Where is the problem?”, they tell you. “We just explained scientifically how things are in heaven.”
Then you open the Pandora’s box,
“Well you have just said that the Sun doesn’t move really, it is the Earth that moves, and hence we see the apparent Sun rise and Sun set.”
Then they say, “Yes, that is the case. The Sun doesn’t move, but the Earth does.”
You ask, “How do you know this? Do you see that the Earth is moving?”
They say, “The textbook tells us so ” Some of the more knowledgeable ones say that “Galileo proved that the Earth moves and not the Sun. Since we are on Earth, we see only apparent motion of the Sun.”
You say: “But wait, just now you said that the Moon does not move, it is always in the sky. Also you said that the stars do not move, they are there all the time. Now if the Earth moves, then all these bodies should also move, if only, apparently.Then the stars must also move, just like the Sun does, do not forget that Sun is a star too! So other stars should also just set and rise like the Sun, and so should also the Moon!”
Or you can argue just the opposite: “I claim that it is the Sun that moves, Earth does not move. Isn’t it a lot more easier to explain this way, why we do see the Sun moving, because it moves. And we anyway do not see Earth moving! How will disprove me?”
Then the grumbles start. They have never thought about this. They knew the facts, but never connected them. This lead to the misconceptions regarding these things. They were right in parts, but never got a chance to connect the dots, metaphorically speaking.The reason for these misconceptions is the faith in the text-books, but if the text-books fail to perform the job of asking them the right question, where the reasoning alone can get rid of many of the misconceptions.
If we choose the alternative question, of challenging them to disprove that the Earth is stationary, almost most of them are unable to answer the question of disproving that the idea that the Sun moves and not Earth. They would suggest that we can see this from the satellite in the sky (Can we really?).
Most of us take the things for granted and never question many (or as in most cases, any) of them. And many times the facts are something we do not question. We say that “It is a fact.” This statement basically posits that the information which we think is out there can be unquestionable. But there are many flavours of the post-modern philosophy which challenge this position. They think that the facts themselves are relative, that is to say that one culture has different science than another one. But let us leave this, and come back to our problem of the stars and the Sun and Moon.
Lets put out the postulates for the above arguments and try to deduce deductively the results that were obtained.
Claim 1: Sun doesn’t move.
Claim 2: Earth moves.
Observation 1: We see the Sun moving across the sky daily, it rises and it sets.
Explanation 1: Since the Earth moves, and the Sun is stationary, we see that Sun moves apparently. This apparent motion of the Sun is seen as the Sunrise and the Sunset by us. This is what causes the day and night.
But we can have Observation 1 explained by another set of claims, which is exactly opposite, namely, that the Earth doesn’t move but the Sun moves.
Claim 3: The Sun moves.
Claim 4: The Earth does not move.
Explanation 2: Since the Earth does not move, and the Sun does, we just see the Sun passing by in the sky, around the Earth. This causes day and night.
We see that Explanations 1 and 2 are both valid for Observation 1, if the claims 1 and 2, 3 and 4 are true then the respective deductions from them, in this case the Explanations 1 and 2 respectively are also true.So in this case the logical deduction is correct, provided that the Claims or assumptions are correct. But this process does not tell you whether the claims themselves are true or not. But both set of assumptions, cannot be true at the same time. Either the Earth moves or it does not, it cannot be in a state of both. If at all we had an explanation which came from these assumptions which did not correspond with the observations, but was logically deducible, then we can question the assumptions or premises as philosophers call them.
Of course, the things said above and the reasoning given sounds good. So much so that the respondents are convinced that they
understand how things work, and have an elaborate reasoning mechanism
We can have one example of this type.
Assumption 5: Stars do not move, there are so called “fixed stars”.
Assumption 5: During the day time the Sun is too bright, as compared to the other stars.
Now in this case combining Assumption 5 (A5) with Observation 1 (Ob1) we would get the following:
Explanation 3: The stars are too dim as compared to Sun, hence we cannot see them during the day time, but they are present. Hence they do not move.
In Explanation 3 (E3) above the deduction has a problem. The deduction does not follow from the assumption. This is the other problem in which we talked about above.
Most of the people who would suggest these responses have mostly no background in astronomy. Even then the basic facts that Earth goes round the Sun and not the other way round are forced upon them, without any critical emphasis on why it is so. Neither are they presented at point with the cognitive struggle of another view point, namely the geo-centric view. So presenting the learners with opportunities that will make them observe things and make sense of the explanations in light of the assumptions that were made, will enhance the reasoning and help them to overcome some of their misconceptions.
But there is another observation which can be made of the skies. And it can be either done in the classroom with the aid of Free Softwares like Stellarium. After the round of above questions, we usually show the class the rising of the stars from the east. In a darkened room with a projector the effect is quite dramatic for those who have not witnessed such a thing before. So you can show the class, just as the Sun rises, all other celestial bodies like the Moon and the stars also must rise and this is an observed fact.
Observation 2: The stars and planets and the Moon also rise and set everyday.
So how do we make sense of this observation, Ob2 in the light of the assumptions that we have.
Assumption 6: Sun is a star.
Explanation 4: We observe that Sun moves during the day, from East to West. Sun is a star, hence all other stars should also move.
Now why this should be the case will be different for the geo-centric and the helio-centric theories. In case of H-C theory the explantion is simple. The Earth moves hence the stars appear to move in the opposite direction. And this applies to all the objects in the sky.
Since the Earth moves all other celestial objects will appear to move. In case of G-C theory we have to make an assumption that the
stars are “fixed” on some imaginary sphere, and the sphere as a whole rotates.
But coming back to the misconceptions, it is just the ad-hoc belief that the stars do not move (“fixed stars”) in conjunctions with another observation that in presence of too bright objects dim objects cannot be seen leads to belief that the stars are immobile and do not rise and set as the Sun does. There is another disconnection from another fact that they know, or are told in the textbooks, that the apparent movement of the Sun is caused by the actual movement of the Earth. There is no connection between these two facts which is made explicit.
We think that providing opportunities for direct observation aided by software, Stellarium in this case, which help in visualizing the movements of celestial bodies will help in developing the skill of reasoning and explaining an observed phenomena.
Humble hovel or Palace
How slowly one advances in a boat that does not float along with the stream in a specific direction! How much easier it is when one can connect with the work of great predecessors whose value is not doubted by anyone. A personal experiment, a construction whose foundations one must dig himself and whose walls one must erect himself, runs a real risk of becoming a humble hovel. But perhaps one prefers to live there rather than in a palace that has been built by others.
– M. C. Escher | Escher on Escher – Exploring the Infinite
Most of us would have already made the choice. For me the choice is somewhat both maybe the garden of the palace and living space of the hovel. I may try to give up the palace garden sometime in the future but for now it is so. What about you?
Debunking bad science
Debunking bad science should be constant obligation of the science community, even if it takes time away from serious research or seems to be a losing battle. One takes comfort from the fact there is no Gresham’s laws in science. In the long run, good science drives out bad.
We are stardust…
The amazing thing is that every atom in your body came from a star that exploded. And, the atoms in your left hand probably came from a different star than your right hand. It really is the most poetic thing I know about physics: You are all stardust. You couldn’t be here if stars hadn’t exploded, because the elements – the carbon, nitrogen, oxygen, iron, all the things that matter for evolution – weren’t created at the beginning of time. They were created in the nuclear furnaces of stars, and the only way they could get into your body is if those stars were kind enough to explode. So, forget Jesus. The stars died so that you could be here today.
Irony at its best!
The President (well there is only one President, the President of US of A, rest others are just presidents) said,
“In our global economy, we can’t just have a few leaders of the most advanced economies making decisions that touch the lives of billions of people around the world.”
via Firstpost
Isn’t it ironical that President Obama is saying this. Him, his predecessors and his successors have done it, he is doing it, and they will continue to do it. Is it still a secret that the decisions that indeed affect lives of billions of people are taken by “just a few leaders of the most advanced economies.” How do you otherwise explain monopolies of a few companies over most of the economy in the “Free World”?
JEE and school system
“The old JEE (is?) destroying school system, leading to rampant coaching industry, biased in favour of urban areas and boys.”
“IITs cannot pursue excellence at the cost of the school system. They must also have a stake in Board exams.”

What Kapil Sibbal says is maybe true. But the damage is already done. Lets see what is the outcome of this.
The Golem at Large
Recently I completed reading of the second book in the Golem series, the complete being The Golem at Large: What you should know about technology by Harry Collins and Trevor Pinch. The book discusses cases from technology field in which there is a ‘regress’, in even expert people are not able to decide objectively what to make out of results of experiment, which at first sight seem to be so objective.
Some of the examples that they choose are well known, some are not. For example the much famed demonstration by Richard Feynman on O-Rings is brought out from its almost cult status. The demonstration by Feynman when looked at with all the background seems to be very naive. Similarly many other examples de-mythify different examples from different technologies.
Some of the quotes that I have liked are as under.
+ 4 It would, of course, be foolish to suggest that technology and
science are identical. Typically, technologies are more directly
linked to the worlds of political and military power and business
influence than are sciences.
+ 6 But disputes are representative and illustrative of the roots of
knowledge; they show us knowledge in the making.
+ 10 It would be wrong to draw any conclusions for science and
technology in general from wartime statements; wartime claims
about the success of the missile reflect the demands of war rather
than the demands of truth.
+ 28 As always, if only we could fight the last war again we would
do it so much better.
+ 28 Just as military men dream of fighting a war in which there is
never any shortage of information or supplies, while the enemy
always does the expected, so experts have their dreams of
scientific measurement in which signal is signal and noise follows
the model given in the statistical textbooks. As the generals
dream of man- oeuvres, so the experts dream of the mythical model
of science.
+ 28 Even when we have unlimited access to laboratory conditions, the
process of measurement does not fit the dream; that was the point
of our earlier book ¡V the first volume of the Golem series.
+ 32 Skimp, save and cut corners, give too much decision-making
power to reckless managers and uncaring bureaucrats, ignore the
pleas of your best scientists and engineers, and you will be
punished.
+ 38 Whether two things are similar or different, Wittgenstein
noted, always involves a human judgement.
+ 40 The `correct’ outcome can only be achieved if the experiments or
tests in question have been performed competently, but a competent
experiment can only be judged by its outcome.
+ 62 The treatment of the controversial aspects must be different to
the uncontroversial aspects. The same is true of what we loosely
refer to as experiments: one does not do experiments on the
uncontroversial, one engages in demonstrations.
+ 64 In an experiment, that would be cheating, but in a display, no
one would complain. A demonstration lies somewhere in the middle
of this scale. Classroom demonstrations, the first bits of science
we see, are a good case. Teachers often know that this or that
`experiment’ will only work if the conditions are `just so’, but
this information is not vouchsafed to the students.
+ 64 A demonstration or display is something that is properly set
before the lay public precisely because its appearance is meant
to convey an unambiguous message to the senses, the message that
we are told to take from it. But the significance of an experiment
can be assessed only be experts.
+ 71 Anything seen on television is controlled by the lens, the
director, the editor and the commentators. It is they who control
the conclusions that seem to follow from the `direct evidence of
the senses’.
+ 74 The public were not served well, not because they necessarily
drew false conclusions, but because they did not have access to
evidence needed to draw conclusions with the proper degree of
provisionality. There is no short cut through the contested
terrain which the golem must negotiate.
+ 77 A vast industry supported by national governments makes sure it
understands how oil is found, where it is found and who has the
rights to find it.
+ 82 In some ways it is easier to delve into the first few
nanoseconds of the universe than to reconstruct something buried
deep in the core of the earth.
+ 86 This is the `experimenter’s regress’. If you believe that
microbiological activity exists at great depths then this is
evidence that a competently performed experiment has been carried
out. If you believe that microbiological activity is impossible or
extremely unlikely then the evidence of biological activity is
evidence for doubting the experiment. Experiment alone cannot
settle the matter.
+ 91 In short, Gold’s non-biological theory and its assessment are
intertwined with the politics and commerce of oil
exploration. There is no neutral place where a `pure’ assessment
of the validity of his claims can be made.
+ 96 With several hundred equations to play with, this is an area
where `theory’ and `guesswork’ are not as far apart as
conventional ideas about science would encourage us to think.
+ 102 I think there are really two different approaches. One is to
say that this is a branch of science and that everything must be
based on objective criteria which people can understand. The other
is to say that is just too inflexible, and that there’s something
called judgement – intuition if you like – which has its place in
the sciences and that it’s the people who are intuitive who are
successful.
+ 104 It is also possible to argue that modellers who did not suffer from big
mistakes were lucky while some others were unlucky to have been wrong.
+ 106 Even if you believe that large errors are bound to prove you
wrong, you may still argue about the meaning of `large’ and you
may still think that the difference between accuracy and
inaccuracy was not clever economics but luck. Finally, you may
always say that the economy changed radically.
+ 106 … it was not the model but the economy that was wrong.
+ 107 The experimenter’s regress occurs when scientists cannot
decide what the outcome of an experiment should be and therefore
cannot use the outcome as a criterion of whether the experiment
worked or not.
+ 107 Oh absolutely, that’s why it’s absolutely pointless to publish
these forecast error bands because they are extremely
large. . . . I’m all for publishing full and frank statements but
you see the difficulty [with] these standards errors is that
they’re huge.
+ … In fact, we could have done this at the National Institute in
the mid 70s, but we suppressed it on the grounds that the standard
errors were so large, that it would have been difficult for
non-specialists, you know people using the models, using the
forecasts, to appreciate. It would have discredited them.
+ 108 Science is often used as a way of avoiding responsibility;
some kinds of fascism can be seen as the substitution of
calculation for moral responsibility.
+ 110 That is, it selected those who were `. . . willing to
subordinate their education to their careers’.
+ 111 The economists who build the models deserve credibility, but
their models do not; one should not use the same criteria to judge
expert advice as one uses to judge the coherence of a model.
+ 124 Flipping to and fro between science being all about certainty
and science being a political conspiracy is an undesirable state
of affairs.
+ 149 In effect, a group of lay people had managed to reframe the
scientific conduct of clinical research: they changed the way it
was conceived and practised.
+ 151 Feynman gives the impression that doubts can always be simply
resolved by a scientist who is smart enough.
+ 151 The danger is always that enchantment is the precursor of
disenchantment.
+ 153 Golem science and technology is a body of expertise, and
expertise must be respected. But we should not give unconditional
respect before we understand just what the expertise comprises and
whether it is relevant. To give unconditional respect is to make
science and technology a fetish.
