Explosives or Not
We have earlier seen some quotes from the book The Golem: What You Should Know About Science. There are two companion volumes to this book The Golem Unleashed: What You Should Know about Technology and Dr. Golem: How to think about Medicine. These series of books by Harry Collins and Trevor Pinch provide us with examples from these fields which most of the times are ‘uncontested’. For example in the first volume they discuss about the famous 1920 experimental confirmation of Einstein’s predictions in general relativity by Eddington. This experiment is told as a matter-of-fact anecdote in physics, where petty borders of nationalism could not stop physics and physicists. But in the book, as they show inspite of scanty or almost no positive evidence, Eddington “Concluded” that the predictions were true. This they term “experimenters’ regress”.
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.
– The Golem Unleashed pp. 106
In The Golem Unleashed they present us with many examples of this from field of technology. One of the examples is from the Challenger accident which Feynman made famous by courtroom drama. In this case they call the “experimenter’s regress” as “technologist’s regress”.
Recently I read (all further quotes from the same link)an episode in India which would fit in very with these episodes. This is regarding baggage scanning machines installed at Indian airports. They were brought at 2 crore rupees per unit in 2010. But in August 2011 they failed the tests on tasks they were supposed to do.
The scanners are called in-line baggage inspection systems as they scan bags that go into the cargo hold of the aircraft after passengers check in and hand over their luggage to the airline. They use x-ray imaging and “automatic intelligence” to verify the contents of bags and determine whether they include explosives.
Now one would think that this would be as easy as it gets. Either the scanner detects whether the explosives are present in the baggage or they do not. But it is not as simple as it seems so. Now when the tests were done, the testers found the machines failed.
During the tests, security sources said that a technological specification committee of officials from the IB, RAW, SPG, NSG, BCAS and the civil aviation ministry passed bags containing 500 gm of six kinds of explosives, including PETN and ammonium nitrate, as well as IEDs through these systems. The scanners did not flag any of these bags as suspicious, the sources said.
So after this “failure” the companies which supplied these machines were asked to improve upon the machines or to share the software to recalibrate them. But the companies and interestingly Airport Authortiy of India AAI said that the testing methods were at fault. Now the explosives were passed and the machines did not detect them, then how can companies say that the testing methods were not working?
The machines work on the so called 70:30 principle.
“Though it works on a 70:30 principle, if there is an explosive in the 70 per cent, it will throw up the image of each and every bag that has dangerous substances. We would like to emphasise that the systems supplied and installed by our company at Indian airports are of state-of-the-art technology and are fully compliant with current standards.”
The 70:30 principle refers to the “automatic intelligence” used by Smiths Detection machines to clear 70 per cent of the baggage and reject the rest, according to the Airports Authority of India (AAI). “The machines reject 30 per cent of the baggage, the images of which are then sent to the screener. These systems have automatic intelligence capability and have been tested against a wide range of substances considered dangerous for aircraft. The details and specifications are never disclosed, or else terrorists would understand the software,”
But if anyway machines are doing the job, why not do it 100%? And the funny thing is that they are not sharing the software, which is the main agenda of the proprietary software companies. This is a case where people realize that they are just Users of the software under question. This argument that “or else terrorists would understand the software” does not hold. They don’t need to if the machine is going to reject a whole lot of bags And in anyway if there are bus/holes in the software, a thousand eyes repair them much faster than a few. And this is The companies further say that
“The technology or physics is that x-ray based system can’t detect explosives, it is only approximate detection of dangerous substances,”
Why is the AAI siding (they are rather defending the companies) with the companies is something worth pondering.
AAI people say “The problem could be due to the sheer ignorance of officers who lacked the skills to test for explosives,”
Still with no unanimity in the testing results, the case truly presents us with a “technologist’s regress.”
Gaza Blitz hailed?
It is important to keep this in mind given the accusations of “disproportionality” being hurled at Israel from all directions. They are hogwash. The Jewish state cannot be faulted — but rather should be hailed — for investing precious human capital and limited financial resources to develop a technological miracle: Iron Dome. By intercepting in the last week upwards of 400 rockets destined for Israeli civilian centres, the anti-missile defence system saved countless Israeli lives. Likewise, it also saved Palestinian lives, which surely would have been lost in the event the IDF was forced to retaliate for a direct hit, say, on Tel Aviv.
This is in stark contrast to Hamas’ practice of concealing weaponry in residential buildings, schools, hospitals and mosques, thereby guaranteeing the unnecessary loss of life despite the precision of Israeli strikes.

Ah! This piece of writing is as crappy – biased – hogwash – etc. etc. (are these the right words?, am at a loss of what words to put here) as it can get. And it is not language that is at fault, by the very idea. The idea that Israel can do anything it wishes, without fearing any consequences is what is through an through present in this line of thoughts. The state of Israel has become the new “Untouchable”. The writer glorifies the killing and pounding of the Gaza region, with a logic that is truly cigol. What he claims as a mere “hogwash”, is the reality which the state of Israel is desperately trying to hide, and this with full support of the corporate and major media houses. Maybe the author is trying to make this fact oblivious (and wants us to be also ) that Israel is the occupying force, and they hold superior fire power. To say killings and bombings should ” but rather be hailed” the author is making an ideological analogy to the holocaust. If someone on the other hand with same argument had replaced Jews instead of Gazans, and justified the killings, there would have been a huge cry over this. If these killings can be justified, no wait, rather hailed now, why are the Israelis so much adamant that people see the faulty logic and the tragedy of the holocaust. I think this is the same only with the Israelis taking up the place of executioners with impeccable cigol to support their actions.
After all as Orwell says:
War is Peace | Freedom is Slavery | Ignorance is Strength
And this is what is exactly being practiced here.
Oh and will I get a phone call for this?
‘to criticise Israel can create major problems. Journalists spoke to us of the extraordinary number of complaints which they receive. We have presented our findings to many groups of media practitioners. After one such meeting a senior editor from a major BBC news programme told us: “we wait in fear for the phone call from the Israelis”. He then said that the main issues they would face were from how high up had the call come (e.g. a monitoring group, or the Israeli embassy), and then how high up the BBC had the complaint gone (e.g. to the duty editor or the director general).’ (p. 2)

May be not because I am not a journalist, neither is my blog very famous!
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?

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.

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.

Gadkari Newspeak
“It’s not important how much money has been earned. It’s important how it has been put to use, whether it has been put to good use or not.”
via Indian Express.
Nitin Gadkari , the incumbent BJP president, is in news for all wrong reasons these days. Apart from the allegations that his business interests have shadyness by IAC activist Arvind Kejriwal, he is also making blunders in quoting and is also facing some rebellion from within his own party. But the quote above comes in his (or his acts?) defence from the RSS camp. And it is amusing too, as at times RSS distances itself from the BJP, saying that it is their internal matter, but at other times also gives self-proclaimed clean-chits to BJP members. It is interesting to note how the very concept and meaning of corruption is being twisted by RSS cheif Mohan Bhagwat in the quote above The act itself is set aside as to whether it is good or bad, while the motive with which the result of the act (the black money) will be utilised determines the morality of the act. Now that being the case how do we decide whether the money is “put to good use or not”? This is an entirely subjective view. Something that is good for a person or a community may be bad for others. For example if someone makes a lot of money and invests it in something else to make more money, then for that person the use is definitely good use, but for others it is not. And there is nothing like free money, corruption happens only when money meant for something else goes to the corrupt person. With this cigol even murders may be justified. Trying to justify the act of corruption by making statements like this one, is making classic Orwellian Newspeak. This just makes the point that the BJP is just another Congress, which comes with a remote control too.
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.
Experiment in The Classroom
“The experiment is already on, Sir! It is my personal experience that the story is a wonderful magic pill that helps to establish rapport between the pupils and the teachers. Those very boys who were not prepared to listen to me on the first day and who had unnerved me with shouts and catcalls, have become quiet since I started telling them a story. They now have a sort of affection for me. They listen to me and sit as I ask them to. I don’t have to shout at them to keep them quiet. And they don’t leave the school even after it is over!”

Hope that every classroom would be like that, where the children like to come and don’t like to go home…
On Division of Education
‘Consider how we design our educational programs. We take the major subjects apart and reduce them to a number of main sub-sections. Then we subdivide the sub-sections. We continue until we have a large collection of little pieces that we believe that children can understand.
‘As a result we present our students with disembodied fragments of subject matter … fragments that they can’t possibly make sense of … fragments that they can’t use for anything. Most of them never sense the full power of the subjects that they encounter.’
