Information is power. But like all power, there are those who want to keep it
for themselves. The world's entire scientific and cultural heritage, published
over centuries in books and journals, is increasingly being digitized and locked
up by a handful of private corporations. Want to read the papers featuring the
most famous results of the sciences? You'll need to send enormous amounts to
publishers like Reed Elsevier.
There are those struggling to change this. The Open Access Movement has fought
valiantly to ensure that scientists do not sign their copyrights away but
instead ensure their work is published on the Internet, under terms that allow
anyone to access it. But even under the best scenarios, their work will only
apply to things published in the future. Everything up until now will have been
lost.
That is too high a price to pay. Forcing academics to pay money to read the work
of their colleagues? Scanning entire libraries but only allowing the folks at
Google to read them? Providing scientific articles to those at elite
universities in the First World, but not to children in the Global South? It's
outrageous and unacceptable.
"I agree," many say, "but what can we do? The companies hold the copyrights,
they make enormous amounts of money by charging for access, and it's perfectly
legal - there's nothing we can do to stop them." But there is something we can,
something that's already being done: we can fight back.
Those with access to these resources - students, librarians, scientists - you
have been given a privilege. You get to feed at this banquet of knowledge while
the rest of the world is locked out. But you need not - indeed, morally, you
cannot - keep this privilege for yourselves. You have a duty to share it with
the world. And you have: trading passwords with colleagues, filling download
requests for friends.
Meanwhile, those who have been locked out are not standing idly by. You have
been sneaking through holes and climbing over fences, liberating the information
locked up by the publishers and sharing them with your friends.
But all of this action goes on in the dark, hidden underground. It's called
stealing or piracy, as if sharing a wealth of knowledge were the moral
equivalent of plundering a ship and murdering its crew. But sharing isn't
immoral - it's a moral imperative. Only those blinded by greed would refuse to
let a friend make a copy.
Large corporations, of course, are blinded by greed. The laws under which they
operate require it - their shareholders would revolt at anything less. And the
politicians they have bought off back them, passing laws giving them the
exclusive power to decide who can make copies.
There is no justice in following unjust laws. It's time to come into the light
and, in the grand tradition of civil disobedience, declare our opposition to
this private theft of public culture.
We need to take information, wherever it is stored, make our copies and share
them with the world. We need to take stuff that's out of copyright and add it to
the archive. We need to buy secret databases and put them on the Web. We need to
download scientific journals and upload them to file sharing networks. We need
to fight for Guerilla Open Access.
With enough of us, around the world, we'll not just send a strong message
opposing the privatization of knowledge - we'll make it a thing of the past.
Will you join us?

Pedagogy of Idea of Power
A paper from much later Papert IBM Journal 2000
“What’s the big idea? Toward a pedagogy of idea power
Here he distinguishes between the psychological (how a person is
affected by a treatment) and epistemological (about ideas) aspects of
learning and assessment. It is rather unfortunate that researchers (much
to Papert’s dismay) choose to study “effects of programming (or of LOGO
or of Computer)” on children after a certain exposure akin to a medical
treatment. This is certainly not what was envisioned by Papert for LOGO
and computers. He also adds that the third word in the subtitle of
“Mindstorms: Children, Computers and Powerful Ideas”, namely powerful
ideas is something that most researchers forgot. They only concentrated
on the earlier two and left the powerful ideas outside the classroom and
the school.
Also for the current practices in the fields of research in education
and especially constructvism which is in vogue now, he has following
critique (which I think is prevalent methodology and framework in our
own centre and applies to them as well):
“Consider Michael’s relationship with school mathematics. Learning how
to find the common denominator of a bunch of fractions is boring for him
because he is not able to use it in any exciting way. It supports
neither flights of the mind nor “hands-on” projects.
Enter a constructivist who says: Michael will have a better relationship
with the manipulation of fractions if he discovers the rules himself. So
situations are created (often with great ingenuity) that will lead
children to “discover” the rules of arithmetic. But being made to
“discover” what someone else (and someone you may not even like) wants
you to discover (and already knows!) is not Michael’s idea of an
exciting intellectual adventure. The idea of invention has been tamed
and has lost its essence. He
wants to fly, but what this kind of constructivism offers him is more
like decorating the captive bird’s
cage.
This failure of the constructivist to meet Michael’s needs represents a
double whammy of disempowerment. Jean Piaget’s very strong idea that all
learning takes place by discovery is emasculated by its translation into
the common practice known in schools as “discovery learning.” It is
disempowered in part because discovery stops being discovery when it is
orchestrated to happen on the preset agenda of a curriculum but also in
large part because the ideas being learned are disempowered. For
example, the idea of rules for manipulating numbers was historically one
of the most powerful ideas ever and in the right context can still be.
But no child would ever
suspect that from its presentation in school as a rather boring routine.
Setting ourselves the task of
re-empowering the ideas being learned is also a step toward
re-empowering the idea of learning by discovery.
The same double whammy is present when the excellent and potentially
powerful intention, that
knowledge is situated, turns into presenting manipulations of fractions
in the guise of “real world” situations such as shopping at the
supermarket. For Michael this contributes nothing to a sense of the
power of the idea of fractions. He cares nothing about shopping in the
supermarket and knows that
in these days of automation at the checkout counter and unit prices on
the labels, no one exercises arithmetic while shopping.”
In this article he also talks about why school reforms are impossible
but change is not.
“So, too, the mega-change in education that will undoubtedly come in the
next few decades will not be
a “reform” in the sense of a deliberate attempt to impose a new designed
structure. My confidence in making this statement is based on two factors:
(1) forces are at work that put the old structure in increasing
dissonance with the society of which it is
ultimately a part, and
(2) ideas and technologies needed to build new structures are becoming
increasingly available.
I hope that publishing this paper will help both factors. Public
discussion of the idea-averse
nature of School makes the dissonance more acute. Public access to
empowered forms of ideas and the ways in which technology can support
them fertilizes the process of new growth.”
Most of the people who are averse to technology for various reasons, are
essentially ignoring the fact that new epistemological and relational
structures among the learners and the things to be learned have started
to form due to current technologies, which were impossible earlier. The
very ignorance of the fact that these structures are changing the
dynamics of knowledge and ideas around us, sometimes knowingly and
patronizingly, will not lead us anywhere but keep us in an idea aversion
mode.
Radical Openness – Scientific Research
“The more we’re getting into this the more it’s apparent this is a radical new way to scientific research. Traditional research is done in an institution with patent protection. IP protection and patents slows progress because it reduces collaboration and makes it harder to build on the work of others. Our project, we don’t have a central body. It’s the public, they’re the ones who get excited. Because we’re not beholden to shareholders we can create a community.”

I just hope that this project is successful and will create a new way of doing scientific research which will involve common people.
Aaron Was a Criminal and So Are You
Make no mistake, Aaron was a criminal and, despite popular belief, there was no prosecutorial overreach. The US Attorney who oversaw his prosecution described her office’s actions as “appropriate” and, according to the law, she was telling the truth. The job of prosecutors is to bully and intimidate suspects, using the threat of some of the world’s harshest sentencing laws into plea bargaining for a shorter sentence in exchange for an admission of guilt. This is American “justice;” our current system of severe sentencing and mandatory minimums gives prosecutors overwhelming power – power that was once in the hands of judges and juries – to the point that today less than 5% of criminal cases are resolved by a jury (3% in federal cases).

Sharing knowledge and learning collaboratively at schools
(This article was written for a college magazine.)
We have a vision for a better society in which the values of sharing and collaborating knowledge and technical know-how form an integral part. There are two aspects to this issue. One is why it should be done, and given the current social structure how it can be done. Though the why question is as important as the how one in this article we will try to focus more on how it can be done with aid of proper technology and what are the possible implications of this intervention to the citizens of the future.
The current education system does little to promote and impart the ideas of sharing knowledge with peers to the students who will be the future citizens. In our educational system it is more like each-one-for-oneself; if you help your peers you will be at a loss in the future. Another aspect is that the educational system by its nature is consumerist. By consumerist we mean that the schools system treat the students more like consumers, who are then passively fed in what has already been produced by others. There is no or little scope left for students to produce or construct anything meaningful. So the platform/technology which will address these issues should have the following qualities:
- It should be based on principles of Free Software (see http://gnu.org/education).
- It should allow for collaboration / sharing of knowledge.
- It should allow for active, meaningful and collaborative production / construction contexts, through which students will learn.
- It should give immediate feedback to the student, not the delayed one (year end) which the current school system has. This is essential as it makes children reflective about the work that they are doing.
Learning in the context of constructing some tangible thing is a philosophy of education proposed by Seymour Papert, called constructionism. Constructionist learning is inspired by the constructivist theory that individual learners construct mental models to understand the world around them. However, constructionism holds that learning can happen most effectively when people are also active in making tangible objects in the real world. A closely related term that you might have heard is that of constructivism, but there are differences though.
The potential for transforming classrooms in a revolutionary way is present in the constructionist way of learning, which the existing CBTs (computer based tutorials) do not challenge but reinforce. The advances in technology have made it possible now to implement constructionist ways of learning to masses. So where are the examples of this?
The Sugar learning platform is just one such example which is specifically developed keeping in mind the above considerations. But the idea of constructionist learning is not limited only to using computers. displayed. The very idea of the platform is centered around the idea of constructionism. Though initially developed for OLPC (One Laptop Per Child) Project, now it can run on almost all computers. Learning in an environment where sharing knowledge is an inherent principle rather than an added externality provides the students with a whole new way of learning. Each activity on Sugar is designed keeping in mind the collaborative, construction context and immediate feedback principles.
The Sugar platform provides construction contexts from different areas to learn collaboratively like language, mathematics, science, drawing, music, games, programming, photography, audio and video recording among other things. For each of this activity can be done collaboratively by the students and can be shared with others. This also provides students to make meaningful connections between different concepts. In this context we have seen a strong urge in the children to share the knowledge and activities that they have with others, but in the current school system there is no or little provision for this. Sharing of activities provides context for feedback from peers, which in turn is fruitful in improving learning. Thus we see that the tools and time is ripe for changing our perspective towards education for a more inclusive and better society, whose core values are sharing of knowledge and collaboration.
There are pilot projects of Sugar running at many places across India, one is the Khairat Project which is running successfully for past 4 years at a primary tribal school of first generation learners near Mumbai, another one is at Merces School near Panaji in state of Goa.
Does Tulsi has environmental benefits too?
Recently there was a news item in Times of India which had the same heading as that of this particular post. The news claimed
(Around two decades back Dada Dham, a socio-spiritual organization brought together a team of botanists, ayurvedic scholars and environmental enthusiasts to study the environmental benefits of tulsi.)NAGPUR: Ayurvedic medicinal values of Tulsi are well known. Our ancient scriptures have enumerated the medicinal benefits of tulsi. Its extracts are used widely for curing common ailments like common cold, headache, stomach disorder etc.
But the environmental benefits have been comparatively unknown. Around two decades back Dada Dham, a socio-spiritual organization brought together a team of botanists, ayurvedic scholars and environmental enthusiasts to study the environmental benefits of tulsi.
Now the next claim from an “eminent botanist” that the report does is startling indeed.
“Tulsi gives out oxygen for 20 hours and ozone for four hours a day along with the formation of nascent oxygen which absorbs harmful gases like carbon monoxide, carbon dioxide and sulphur dioxide from the environment,” said Shyamkant Padoley, an eminent botanist.
How would the tulsi plant (Ocimum tenuiflorum) do this? Is it anatomically so different that it is capable to do this? How does the plant regulate this 20 and 4 hour cycle? I would really like to know. How is that no other plants have this cycle? How did they detect presence of ozone, what detectors they used? What mechanisms in presently known cycle of photosynthesis account for this cycle? And if this is part of the standard photosynthesis process, then all plants should have it. This seems fishy, and a most preliminary search did not yield any positive result. All of them talk about production of oxygen and not ozone, as reported by Padoley. And if this is indeed true, it might lead to change in our conception of the photosynthetic cycle.
And if the ozone report is to be believed at all then this is what ozone does to you quote from Wikipedia article on ozone:
Ozone is a powerful oxidant (far more so than dioxygen) and has many industrial and consumer applications related to oxidation. This same high oxidizing potential, however, causes ozone to damage mucus and respiratory tissues in animals, and also tissues in plants, above concentrations of about 100 parts per billion. This makes ozone a potent respiratory hazard and pollutant near ground level.…There is evidence of significant reduction in agricultural yields because of increased ground-level ozone and pollution which interferes with photosynthesis and stunts overall growth of some plant species. The United States Environmental Protection Agency is proposing a secondary regulation to reduce crop damage, in addition to the primary regulation designed for the protection of human health.…There is a great deal of evidence to show that ground level ozone can harm lung function and irritate the respiratory system.Exposure to ozone and the pollutants that produce it is linked to premature death, asthma, bronchitis, heart attack, and other cardiopulmonary problems.…
Ozone is air pollutant, green house gas.
To summarize this is that ozone is NOT GOOD for us at ground level! It may do us good in upper atmosphere to block UV Rays, but down here on ground it is bad. And if this claim of ozone production by Tulsi is true why is the campaign of “Tulsi lagao pradushan hatoa (Plant tulsi, remove pollution)” which follows in the article is being implemented?
Padoley, member of technical committee, ministry of environment and forest, NewDelhi, and forest tech committee, also read a paper at the International Conference on Occupational Respiratory Diseases at Kyoto in 1997 where cyclo oxygenate, an enzyme only found in tulsi was labelled for the first time. This enzyme regulates the entire mechanism of oxygen evolution. (emphasis added)
This again I am unable to understand. It says this enzyme is “only found in Tulsi”, and it also “regulates entire mechanism of oxygen evolution”. One can agree that a particular enzyme is found in a particular plant, but if this enzyme controls “entire mechanism of oxygen evolution”, how do other plants regulate their mechanisms of oxygen evolution.
Dada Dham initiated a campaign ‘Tulsi Lagao Pradushan Hatao’ in 1987 under the guidance of Narendra Dada, the institution’s head. It was under this campaign that the above mentioned panel of experts was formed. After finding out the environmental benefits of the plant, Dada Dham organized a number of programmes like street plays, nukkad sabhas and lectures to propagate the use of the plant.
Dr Dattatraya Saraf, an ayurvedic doctor and expert said, “The plant enriches the environment with oxygen almost 24X7 and also absorbs other pollutants.” He further added that if the size of the plant can be increased, the environmental benefits can be increased.
This statement that “plant enriches the environment with oxygen almost 24X7” is in contradiction to statement by above Padoley regarding 20 and 4 hour cycles. Which one is to be believed? And mind you this is just appearing a few lines later, this is either very poor editing and reporting, or hogwash to the public.
“That is why we want to urge scientists and concerned authorities to make research on the issue of increasing the height of tulsi plant. If big trees can be converted to bonsai plants then big tulsi trees can be possible too,” said Kishor Verma, PRO of Dada Dham.
This is another statement that I would like to contest. Did they compare the rate of oxygen production vis-a-vis to other plants. That is to say simply did they have any control sample? And does making “tulsi tree” make any sense (can one really do it is another question), will it really increase oxygen making capabilities, is it a linear relationship between these two variables? The water is completely muddy in this !
He also citied the research and work by other organization in support of tulsi’s environmental benefits.
“The forest department of Uttar Pradesh, with the help of an organization called Organic India Limited, Lucknow planted lakhs of tulsi saplings around Taj Mahal to protect its surface from industrial emissions. This step has yielded positive results,” Verma said.
“We are just asking the administration to take notice of these extra ordinary benefits of tulsi and take steps for utilizing them. Even simple steps like planting tulsi plants on road dividers, parks etc can bring a difference,” said Verma.
The reporter and also the editor make no effort to correct these glaring inconsistencies in the report itself, forget about doing nay research on the topic, or verifying the claims made by these people. Maybe this was like the paid news that is talked about a lot these days.
What I find here i that the agenda of what is to be done was already set, the conclusions were already drawn, by our ancestors, written in black and white in ancient texts. The point was only to justify what they were doing, and trying to provide a “scientific basis” of what they already believed to be true (for whatever reasons, mostly religious, and presence of a religious organization in this sort of confirms this).
A good example of pseudo-science and bad science reporting.
Science, a humanistic approach
Science is an adventure of the whole human race to learn to live in and perhaps to love the universe in which they are. To be a part of it is to understand, to understand oneself, to begin to feel that there is a capacity within man far beyond what he felt he had, of an infinite extension of human possibilities . . .
I propose that science be taught at whatever level, from the lowest to the highest, in the humanistic way. It should be taught with a certain historical understanding , with a certain philosophical understanding , with a social understanding and a human understanding in the sense of the biography, the nature of the people who made this construction, the triumphs, the trials, the tribulations.

Computers in Teaching and Learning
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.

CURE Logo
In earlier post we had seen the CUBE Logo, now in this post we will see, CURE Logo. CURE stands for a cure of problems of CUBE and is Collaborative Undergraduate Research and Education. The idea is to propagate the spirit and activities via making many-many centres across India and when one centre gets the know-how, it starts acting as a centre itself. This has enormous potential and is also not so easy, if we are planning to form a network of 20,000 odd colleges across India. Hats off to this initiative by Dr. M. C. Arunan.
Since the idea was to propagate the via forming numerous nodes, and absence of a centralized structure, we came up with the Pythagorean Tree as one of the possible candidates for the logo. The Pythagorean Tree is a fractal structure which is self similar. This also reflects the spirit of CURE and CUBE, that the size of the institute or its location should not reflect on the facilities or the opportunities that it provides to its students.
In this program an initial batch of students , lets call them Batch-0 is trained for performing a series of experiments . At end of their training which is a hands on, they give a talk on their work. In the next step, these students build these facilities at their alma mater and maintain them. This is the first iteration of the program. After this iteration, the Batch-0 students, who have handled these biological systems for some time now and carried out some investigations become mentors for the next batch of students. Lets call these as Batch-1. Now we conduct another session of training, in this the Batch-0 students act as mentors for Batch-1 students. Thus at end of this training another iteration of the programme is completed. So the second iteration builds on the first one. Then for the Batch-2 students, the students from earlier batches act as mentors, thus at each stage we are increasing the mentors as well as the facilities available for doing research. Iteratively, collaboratively we can sure reach the 20,000 odd under-graduate colleges in India
In the logo the base triangle forms the basis of all the structure, this we call as Batch-0, and rest of all others are based on this. And since this is an iterative, self-similar figure, none of them are different from one another, neither are the squares different. For example the small branch sitting on top of the large branch is a similar to the larger branch. If we scale it. it would be the same.
Lack of research facilities at the undergraduate level , is most often cited as cause for poor education at that level. And the facilities come expensive. This was we can make in-expensive or some times zero-expense facilities for college education and get the students involved. This logo is released under Creative Commons Share Alike License.

Science And Certainty
Science is not about certainty. Science is about finding the most reliable way of thinking, at the present level of knowledge. Science is extremely reliable; it’s not certain. In fact, not only it’s not certain, but it’s the lack of certainty that grounds it. Scientific ideas are credible not because they are sure, but because they are the ones that have survived all the possible past critiques, and they are the most credible because they were put on the table for everybody’s criticism.
The very expression ‘scientifically proven’ is a contradiction in terms. There is nothing that is scientifically proven. The core of science is the deep awareness that we have wrong ideas, we have prejudices. We have ingrained prejudices. In our conceptual structure for grasping reality there might be something not appropriate, something we may have to revise to understand better. So at any moment, we have a vision of reality that is effective, it’s good, it’s the best we have found so far. It’s the most credible we have found so far, its mostly correct.

This is something that I think separates science from religion. Religion is about absolutes, trust in the absolute God. And this is the difference that should be also taught to the students of science.
