Reading in e-book era

Reading without surveillance, publishing without after-the-fact censorship, owning books without having to account for your ongoing use of them: these are rights that are older than copyright. They predate publishing. They are fundamentals that every bookseller, every publisher, every distributor, every reader, should desire. They are foundational to a free press and to a free society. If you sell an ebook reader is designed to allow Kafkaesque repossessions, you are a fool if you expect anything but Kafkaesque repossessions in their future. We’ve been fighting over book-bans since the time of Martin Luther and before. There is no excuse for being surprised when your attractive nuisance attracts nuisances.

I agree completely.Though cases like these are going to become more common, unless we switch to a technology which we can see that is Free as in Freedom. Governments and corporates are going to use this technology against the people who are using it. It will create profiles of “dangerous” people who are reading revolutionary material, for example. It will go unchecked if we just are using the technology without questioning it.

Drugs and Education

“Education is not getting people jobs in the state and that hurts the self esteem of the youngster. The poor quality of our education system is completely out of tune with the job market. Given their easy supply in the state, drugs become the first crutch of support for all the alienated youngsters floating around,” the doctor continues.

The above article is on the grim situation of drug abuse among the youth in Punjab. Poor quality of education and lack of suitable jobs afterwards is one of the reasons cited for this, others include proximity to Afghanistan and Pakistan, huge influx of capital after the Green revolution.
Just an afterthought, isn’t education itself like a drug? Let me elaborate on what I mean to say. Drugs are supposed to enhance your mental state, they cater to our so called “pleasure centres” in the brain. And they are also supposed to inhibit certain things that we might do naturally. Doesn’t education also do the same. Does it not hinder many of the natural things that we would have done if not ‘educated’? Maybe the current education system places us on highs “meritocracy?” that the plights of the fellow humans are not supposed to affect us! If someone fails in the exam, it is to our advantage at times, as there will be less competition for the resources that are limited, we are told! Thus we are slowly de-sensitized from being human, riding on the high that we get from our personal success. But it is not limited only to us, it is a social drug, not only your own, but your parent’s and relatives and friends’ pleasure centres are also excited. And they would say we have a smarty amongst us. This is what keeps us going forever in pursuit of further education and that at expense of others. But is it not natural, if they don’t perish you won’t survive. And by the time you are fully educated, you get a decent job, you marry, have kids… and the cycle repeats itself, you tell the same things to kids.
So education in the current  is like a mass hallucination, which goes from generation to generation, spread over both time and space, legitmising ills spread in the society…

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.

The Tyger – William Blake

The Tyger is a poem by William Blake, a English poet, painter and print maker. Blake’s works are considered seminal in poetry and visual arts. This is part of the book called The Songs of Experience published in 1794. It is one of Blake’s most known and analysed poems. Many of the facsimile prints can be seen here.

In the original print the poem is illustrated.

Tyger Tyger, burning bright,
In the forests of the night :
What immortal hand or eye,
Could frame thy fearful symmetry?
In what distant deeps or skies
Burnt the fire of thine eyes?
On what wings dare he aspire?
What the hand dare seize the fire?
And what shoulder, & what art,
Could twist the sinews of thy heart?
And when thy heart began to beat,
What dread hand? & what dread feet?
What the hammer? what the chain,
In what furnace was thy brain?
What the anvil? what dread grasp
Dare its deadly terrors clasp?
When the stars threw down their spears
And water’d heaven with their tears :
Did he smile his work to see?
Did he who made the Lamb make thee?
Tyger, Tyger burning bright
In the forests of the night :
What immortal hand or eye
Dare frame thy fearful symmetry?

I first read this poem in the Rendezvous With Rama series by Arthur C. Clarke and Gentry Lee. In the book one of the characters is overwhemled by the appeareance of the giant space-ship named Rama and in wonder says the lines from Blake’s Tyger.
As a species tiger is seriously endangered and its survival depends on just a few thousand (~ 1.5 K) indivduals left in the wild. They say that if immediately steps are not taken, we might not see the tiger in wild beyond the second decade of the century. Illegal poaching and destruction of the habitat are mainly responsible for exponential decline in the tiger population in the country.

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?

Kafka and Orwell

Two of my favourite authors. Both of them were from almost same era, early part of 20th century. Both of them wrote about bureaucracy, corruption, control, power, and helplessness of individuals in the greater scheme of things. Reading them a dark feeling covers your soul, and all chances of redemption appear bleak. We are, it seems, doomed for life, and only non-existence in to oblivion or death can relieve us of these torments, as it does to many characters of this duo.
The things that are happening now around us, the FUDs and stereotyping of “The Enemy” reminds one much of the situation in Nineteen Eight Four. Maybe the policy makers grew up reading Nineteen Eight Four and found enough material to be implemented in the real world. Or as it happens in The Castle, one can easily identify with the main protagonist whose life is made into an unending sequence of visits to the offices in The Castle. As it happens during visits to most of the government offices.
