Round Earth: The Proofs

What is the evidence for a round Earth?

In this post, we explore some of the evidence for proving that the Earth is indeed spherical in shape (if not a perfect one), and not a flat one. Though in the current age we can all point to the images of Earth taken from space  (like the one shown below)

In the age of satellites is easy for us to dismiss the doubting minds who think that the Earth is not flat. But this was always not so. Apart from the evidence from the space age, people in the past had good evidence and arguments for believing that the Earth was indeed spherical in shape and not flat or any other shape. Somehow this misconception that all ancient people considered that the Earth was flat, was generated in nineteenth-century science books.

Ancient evidence

telescope_0008

It is commonly believed that people till very recently believed that the Earth is flat and that some European explorers, by circumnavigating the Earth, proved that it was round. But this is not correct. Ancient Greeks already knew about the spherical shape of the Earth, and it forms the basis of many cosmological models that they built. This, in turn, had implications for the philosophical worldview of the ancient

Aristotle presents us with one of the first evidence for the roundedness of the Earth. For the ancient Greeks, the circle and the sphere presented the perfect form in nature. This was also tied to their worldview in which the celestial and terrestrial was demarcated from each other. The celestial bodies, which included the planets and stars were supposed to be perfect. There were seven planets known to the ancients, which included the Sun and the Moon. The planets were supposed to be spherical themselves revolving with a constant speed in circular orbits around the Earth. One of the core assumptions was that the heavens are unchangeable. So anything that was considered celestial was by definition (a) perfect (spherical or circular), (b) unchangeable (constant). So any mechanism that explained celestial phenomenon had to include these two concepts.

 

The cosmology of the ancient Greeks then was built upon these basic assumptions which were non-negotiable for them. This lead to the formation of various models based on the basic theme of a fixed Earth and planets on circular orbits moving constant speeds. Due to these assumptions and also due to some observed phenomena, led to the conclusion that Earth should also be indeed spherical.

Let us look at the arguments given by Aristotle in this regard. This is from Book II of On the Heavens.

The shape of the heaven is of necessity spherical; for that is the shape most appropriate to its substance and also by nature primary.

Part 11

With regard to the shape of each star, the most reasonable view is that they are spherical. It has been shown that it is not in their nature to move themselves, and, since nature is no wanton or random creator, clearly she will have given things which possess no movement a shape particularly unadapted to movement. Such a shape is the sphere, since it possesses no instrument of movement. Clearly then their mass will have the form of a sphere. Again, what holds of one holds of all, and the evidence of our eyes shows us that the moon is spherical. For how else should the moon as it waxes and wanes show for the most part a crescent-shaped or gibbous figure, and only at one moment a half-moon? And astronomical arguments give further confirmation; for no other hypothesis accounts for the crescent shape of the sun’s eclipses. One, then, of the heavenly bodies being spherical, clearly the rest will be spherical also.

In Part 13 of the book Aristotle talks about the shape of the Earth.

There are similar disputes about the shape of the earth. Some think it is spherical, others that it is flat and drum-shaped. For evidence they bring the fact that, as the sun rises and sets, the part concealed by the earth shows a straight and not a curved edge, whereas if the earth were spherical the line of section would have to be circular. In this they leave out of account the great distance of the sun from the earth and the great size of the circumference, which, seen from a distance on these apparently small circles appears straight. Such an appearance ought not to make them doubt the circular shape of the earth. But they have another argument. They say that because it is at rest, the earth must necessarily have this shape. For there are many different ways in which the movement or rest of the earth has been conceived.

Here we see the cognisance of the fact that the curvature tends to be linear when see it is too large. Aristotle then goes on to discard the ideas by Anaximenes, Anaxogoras and Democritus who claim that flatness of the Earth is responsible for it being still. He argues, even a spherical Earth can remain at rest. The Earth being at rest and it being spherical are related. In Part 14 he takes this discussion further. The first argument uses the symmetry of weight distribution.

Its shape must necessarily be spherical. For every portion of earth has weight until it reaches the centre, and the jostling of parts greater and smaller would bring about not a waved surface, but rather compression and convergence of part and part until the centre is reached.

He further argues using reasoning of additional weight distribution how a spherical Earth can still be

If the Earth was generated, then, it must have been formed in this way, and so clearly its generation was spherical; and if it is ungenerated and has remained so always, its character must be that which the initial generation, if it had occurred, would have given it. But the spherical shape, necessitated by this argument, follows also from the fact that the motions of heavy bodies always make equal angles, and are not parallel. This would be the natural form of movement towards what is naturally spherical. Either then the earth is spherical or it is at least naturally spherical.

After this, he looks at evidence from lunar eclipses to reason that Earth is indeed spherical.

eclipse

The evidence of the senses further corroborates this. How else would eclipses of the moon show segments shaped as we see them? As it is, the shapes which the moon itself each month shows are of every kind straight, gibbous, and concave-but in eclipses the outline is always curved: and, since it is the interposition of the earth that makes the eclipse, the form of this line will be caused by the form of the earth’s surface, which is therefore spherical.

Finally Aristotle takes into account the fact that stars change their positions in the sky relative to the horizon when we move to North or South, indicating that we are indeed on a spherical surface. This will not happen on a flat surface.

stars

Again, our observations of the stars make it evident, not only that the earth is circular, but also that it is a circle of no great size. For quite a small change of position to south or north causes a manifest alteration of the horizon. There is much change, I mean, in the stars which are overhead, and the stars seen are different, as one moves northward or southward. Indeed there are some stars seen in Egypt and in the neighbourhood of Cyprus which are not seen in the northerly regions; and stars, which in the north are never beyond the range of observation, in those regions rise and set. All of which goes to show not only that the earth is circular in shape, but also that it is a sphere of no great size: for otherwise the effect of so slight a change of place would not be quickly apparent.

Another evidence which can be seen since antiquity is that the masts of the ships on ocean became visible first on the horizon, the ship appear later. This can be simply explained by assuming that the surface of the ocean is curved too.

Thus we have seen the ancient evidence for a spherical Earth. It was well known and well established fact, both theoretically and empirically.

Known knowns, Unknown unknowns

Reports that say that something hasn’t happened are always interesting to me, because as we know, there are known knowns; there are things we know we know. We also know there are known unknowns; that is to say we know there are some things we do not know. But there are also unknown unknowns – the ones we don’t know we don’t know

Rumsfeld

After Nehru…

Longish quotes from London Review of Books from After Nehru by Perry Anderson

To be impressive, however, is not to be miraculous, as Indians and others still regularly describe the political system that crystallised after independence. There was never anything supernatural about it: terrestrial explanations suffice. The stability of Indian democracy came in the first instance from the conditions of the country’s independence. There was no overthrow of the Raj, but a transfer of power by it to Congress as its successor. The colonial bureaucracy and army were left intact, minus the colonisers.

For twenty years, across five polls between 1951 and 1971, Congress never once won a majority of votes. In this period, at the peak of its popularity as an organisation, its average share of the electorate was 45 per cent. This yielded it crushing majorities in the Lok Sabha, amounting to just under 70 per cent of the seats in Parliament. In effect, the distortions of the electoral system meant that at national level it faced no political opposition. At state or district level, this did not hold. But there, the centre had powers that could deal swiftly with any local trouble. These too were heirlooms of the Raj, eagerly appropriated by Congress.

No other system of inequality, dividing not simply, as in most cases, noble from commoner, rich from poor, trader from farmer, learned from unlettered, but the clean from the unclean, the seeable from the unseeable, the wretched from the abject, the abject from the subhuman, has ever been so extreme, and so hard-wired with religious force into human expectation.

Fixing in hierarchical position and dividing from one another every disadvantaged group, legitimating every misery in this life as a penalty for moral transgression in a previous incarnation, as it became the habitual framework of the nation it struck away any possibility of broad collective action to redress earthly injustice that might otherwise have threatened the stability of the parliamentary order over which Congress serenely presided for two decades after independence.

By the end of his life, Nehru would have liked a more presentable fig-leaf for Indian rule, but that he had any intention of allowing free expression of the popular will in Kashmir can be excluded: he could never afford to do so. He had shown no compunction in incarcerating on trumped-up charges the ostensible embodiment of the ultimate legitimacy of Indian conquest of the region, and no hesitation in presiding over subcontracted tyrannies of whose nature he was well aware.

Surrounded by mediocrities, Nehru accumulated more posts than he could handle – permanent foreign minister as well as prime minister, not to speak of defence minister, head of the planning commission, president of Congress, at various times. He was not a good administrator, finding it difficult to delegate, but even had he been, this was a pluralism too far.

Nor was Ambedkar consoled by sanctimonious plaudits for his role in drafting the constitution. He knew he had been used by Congress, and said two years later: ‘People always keep on saying to me: oh sir, you are the maker of the constitution. My answer is I was a hack. What I was asked to do I did much against my will.’

Secularism in India, it is explained, does not mean anything so unsophisticated as the separation of state and religion. Rather – so one version goes – the Indian state is secular because, while it may well finance or sponsor this or that religious institution or activity, in doing so it maintains an ‘equidistance’ from the variegated faiths before it.

As with other oppressed minorities in societies keen to advertise their pluralism, a sprinkling of celebrities – a batsman or film star here, a scientist or symbolic office-holder there – adorns, but doesn’t materially alter, the position of the overwhelming majority of Muslims in India.

What the Armed Forces (Special Powers) Act effectively does in such zones, the young Indian historian Ananya Vajpeyi has written, is ‘to create an entirely separate space within India, a sort of second and shadow nation, that functions as a military state rather than an electoral democracy, and only remains hidden because it is not, at least so far, officially ruled by a general or a dictator’. This space should ‘not be thought of as a zone of exception, but as a contradiction so extreme that it undoes the totality in which it is embedded’, which breaks down into ‘two distinct and mutually opposed regimes’ that form ‘two nations: India and non-India’.

Had the party or state been truly secular, in each case this would have been a priority, but that was the last thing it had in mind. There cannot be a genuinely secular party or state unless it is willing to confront religious superstition and bigotry, rather than truckle to them. Neither party nor state has ever contemplated doing that, because both have rested, sociologically speaking, on Hindu caste society. The continued dominance of upper castes in public institutions – administration, police, courts, universities, media – belongs to the same matrix.

After Independence, Gandhi’s doctrines were consigned to the museum, but his saturation of politics with Hindu pathos lived on.

Indian secularism of the post-independence period had never sharply separated state and religion, let alone developed any systematic critique of Hinduism.

The BJP does not oppose, but upholds secularism, for ‘India is secular because it is Hindu.’

‘Myths have a way of running away with their proponents,’ G. Balachandran, an Indian critic of this outlook, of whom there have not been that many, has remarked: ‘Belief in the essentially secular character of the modern Indian state and society can often be little more than an exercise in self-congratulation which overlooks or rationalises the sectarian religious outlook pervading large areas of contemporary social and political practice.’

Mayawati’s erection of 150,000 statues of Ambedkar, not to speak of two hundred effigies of her party’s elephant symbol and of herself (the largest 24 feet high, and like the rest covered in pink polythene as the state went to the polls in March, on the orders of the Election Commission, so as not to beguile or distract voters), at the cost of more schools and healthcare, offers an extreme case of this identity politics, which does not seek to abolish caste, as Ambedkar had wanted, but to affirm it.

Castes continue to be, as they have always been, and Ambedkar saw, one of the purest negations of any notion of liberty and equality, let alone fraternity, imaginable. That the Indian state has never lifted a juridical finger to do away with them, but in seeking only to ameliorate has if anything legally entrenched them, says more about its secularism than the omission of any reference to it in the constitution, or the belated passage of an amendment rectifying the omission to embellish the Emergency.

With it has come a large measure of convergence between Congress and the BJP in government, each pursuing at home a neoliberal economic agenda, as far as their allies will allow them, and abroad a strategic rapprochement with the United States. Culturally, they now bathe in a common atmosphere in which religious insignia, symbols, idols and anthems are taken for granted in commercial and official spaces alike.

In India democracy never extended very far from government to the parties contending for it, which were always run from the top down. Today, however, many have become something other than the oligarchic organisations into which the political scientists Ostrogorsky and Michels thought all parties must sooner or later turn. With the exception of the communists and the BJP, they have become family firms competing for market shares of the electorate and so access to public office.

Of the ensuing scenery, André Béteille, the doyen of sociologists of India, has written that the ‘abject surrender’ of Congress to a single family, corrupting all other parties, has done irreparable harm to Indian democracy, poisoning the wells of public life.

The court, now self-recruiting, is the most powerful judiciary on earth. It has acquired such an abnormal degree of authority because of the decay of the representative institutions around it. Even admirers are aware of the risks. In the graphic phrase of Upendra Baxi, India’s leading legal scholar and one of the first to bring a public interest suit before the court, it is ‘chemotherapy for a carcinogenic body politic’

Comparing India and China from another angle, one of the most lucid political minds of the subcontinent, Pratap Bhanu Mehta, has observed that in the People’s Republic, where there is no democracy, communist rule is based on output legitimacy: it is accepted by the masses for the material benefits it takes great care to deliver them, however unequally. Whereas in India, democracy allows just the opposite – an input legitimacy from the holding of free elections, that thereby excuses the political class from distributing more than confetti to the masses who have elected them.

Three years later, with typical dishonesty, the Manmohan regime renamed it as ‘Gandhian’ to fool the masses into believing that Congress was responsible for it.

Caste, not class, and alas, least of all the working class, is what counts most in popular life, at once sustaining Indian democracy and draining it of reconstructive energy.

If the poor remain divided against themselves, and workers are scattered and ill-organised, what of other sources of opposition within the political system? The new middle class has turned against mega-corruption, but is scarcely foreign to the bribe and the wink, let alone favours to kin, at its own level of advantage. Besotted with a culture of celebrity and consumption, on spectacularly vapid display in much of the media, and to all appearances hardening in collective egoism, it is no leaven in the social order. The intelligentsia is another matter. There, India possesses a range and quality of minds that perhaps no other developing society in the world, and not that many developed ones, can match. Whether working inside or outside the union, it forms an interconnected community of impressive acuity and distinction. In what kind of relationship does it stand to the country? Intellectuals are often held, quite wrongly, to be critical by definition. But in some societies, the mistake has become internalised as a self-conception or expectation, and so it probably is for most Indian intellectuals. How far do they live up to it?

A rigid social hierarchy was the basis of original democratic stability, and its mutation into a compartmentalised identity politics has simultaneously deepened parliamentary democracy and debauched it. Throughout, caste is the cage that has held Indian democracy together, and it has yet to escape.

In the 1920s the great Tamil iconoclast E.V. Ramasamy could declare: ‘He who invented God is a fool. He who propagates God is a scoundrel. He who worships God is a barbarian.’

Hindu culture, exceptionally rich in epics and metaphysics, was exceptionally poor in history, a branch of knowledge radically devalued by the doctrines of karma, for which any given temporal existence on earth was no more than a fleeting episode in the moral cycle of the soul.

‘In an overwhelmingly religious society,’ one subcontinental scholar has written, ‘even the most clear-sighted leaders have found it impossible to distinguish romanticism from history and the latter from mythology.’

Moral indignation is too precious an export to be wasted at home. That the democracy of his country and the humanity of his leader preside over an indurated tyranny, replete with torture and murder, within what they claim as their national borders, need not ruffle a loyal Indian citizen.

Nobel prizes are rarely badges of political courage – some of infamy – so there is little reason for surprise at a silence that, in one form or another, is so common among Indian intellectuals.

What is true is that no break away from the union is conceivable in this area, not because of any economic impossibility, but because Delhi can unleash overwhelming military force, as it has done for a half a century, to crush any attempt at secession, and can count on exhaustion eventually wearing out all resistance, as it cannot in Kashmir, where the alternatives of independence or inclusion in Pakistan have not left the Valley, and any free vote would prefer either to the Indian yoke.

Still, at the altar of Trimurti, costs are discounted inversely to gains. Unity, whose moral and political deadweight is heavier, is safer from reproach than democracy or secularity.

The dynasty that still rules the country, its name as fake as the knock-off of a prestige brand, is the negation of any self-respecting republic.

Congress had its place in the national liberation struggle. Gandhi, who had made it the mass force it became, called at independence for its dissolution. He was right. Since then the party has been a steadily increasing calamity for the country. Its exit from the scene would be the best single gift Indian democracy could give itself.

The political ills that all well-meaning patriots now deplore are not sudden or recent maladies of a once healthy system. They descend from its original composition, through the ruling family and its affiliates, and the venerations and half-truths surrounding these and the organisation enclosing them.

Time Lapse Film Using Scanner

In this post we will see how to make  a time-lapse animation of something which changes over time, with a scanner. Most probably you have seen some amazing time -lapse photography of different objects. Common examples include the ever changing skyscape, blooming flowers, metamorphosing insects etc. I wanted to do a similar stuff, but due to my lethargy and other reasons I did not. Though the cameras have intervelometer, and I have used it once to take photos of a lunar eclipse, (moon changing position which I was supposed to merge later, but never did), and wanted to do the same with a blooming of a flower. But as Ghalib has said, they were one of those हज़ारों ख्वाहिशें…

The roots of the idea what follows are germinated long back, when I had a scanner. It was a basic HP 3200 scanner. That time I did not have a digital camera, (c. 2002-2003), but then I used the scanner as a camera. I had this project lined up for making collages of different cereals. Though I got a few good images from botanical samples (a dried fern below) as well and also fractals from a sheet of rusting iron. Then, I sort of forget about it.

white-fern-00

Coming to now, I saw some amazing works of art done by scanning flowers. I remembered what had been done a few years back and combined this with the amazing time-lapse sequences that I had seen , the germ began can we combine the two?

http://vimeo.com/22439234

Can we make the scanner, make scans at regular intervals, and make a animation from the resulting images. Scanning images with a scanner would solve problem of uniform lighting, for which you may require an artificial light setup. So began the task to make this possible. One obvious and most easy way to do this is to scan the images manually, lets say every 15 minutes. In this case you setup the scanner, and just press the scan button. Though this is possible, but its not how the computers should be used. In this case we are working for the computer, let us think of making the computer do work for us. In comes shell scripting to our rescue. The support for scanners in GNU/Linux is due to the SANE (Scanner Access Now Easy) Project. the GUI for the SANE is the xsane, which we have talked about in a previous post on scanning books and scanimage is the terminal option for the sane project.

The rough idea for the project is this :

1. Use scanimage to acquire images

2. Use some script to make this done at regular time intervals.

3. Once the images are with use, combine them to make a time-lapse movie

For the script part, crontab is what is mostly used for scheduling tasks, which you want to be repeated at regular intervals. So the project then became of combining crontab and scanimage. Scanimage has a mode called --batch in which you can specify the number of images that you want to scan and also provides you with renaming options. Some people have already made bash scripts for ADF (Automatic Document Feeders), you can see the example here. But there seems to be no option for delay between the scans, which is precisely what we wanted. To approach it in another way is to introduce the the scanimage command in a shell script, which would be in a loop for the required number of images and you use the sleep command for the desired time intervals, this approach does not need the crontab for its operation. But with I decided to proceed with the crontab approach.

The first thing that was needed was to get a hang of the scanimage options. So if your scanner is already supported by SANE, then you are good to go.

$scanimage -L

This will list out the devices available for scanning. In my case the scanner is Canon Lide 110, which took some efforts to get detected. For knowing how to install this scanner, if it is not automatically supported on your GNU/Linux system, please see here.

In my case it lists out something like this:

device `genesys:libusb:002:007' is a Canon LiDE 110 flatbed scanner

If there are more than one devices attached to the system the -L option will show you that. Now coming to the scan, in the scanimage programme, we have many options which control various parameters of the scanned picture. For example we can set the size, dpi, colour mode, output type, contrast etc. For a complete set of options you can go here or just type man scanimage at the terminal. We will be using very limited options for this project, namely the x, y size, mode, format, and the resolution in dpi.

Lets see what the following command does:

$scanimage -d genesys:libusb:002:006 -x 216 -y 300 --resolution 600dpi --mode Color --format=tiff>output.tiff

-d option specifies the device to be used, if there is nothing specified, scanimage takes the first device in the list which you get with -L option.

-x 216 and -y 300 options specify the size of the final image. If for example you give 500 for both x and y, scanimage will tell us that maximum x and y are these and will use those values. Adjusting these two values you will be able to ‘select’ the area to be scanned. In the above example the entire scan area is used.

--resolution option is straight forward , it sets the resolution of the image, here we have set it to 600dpi.

--mode option specifies the colour space of the output, it can be Color, Gray or Lineart

--format option chooses the output of the format, here we have chosen tiff, by default it is .pnm .

The > character tells scanimage that the scan should be output to a file called “output.tiff”, by default this will in the directory from where the command is run. For example if your command is run from the /home/user/ directory, the output.tiff will be placed there.

With these commands we are almost done with the scanimage part of the project. With this much code, we can manually scan the images every 15 minutes. But in this case it will rewrite the existing image. So what we need to do is to make sure that the filename for each scan is different. In the --batch mode scanimage takes care of this by itself, but since we are not using the batch mode we need to do something about it.

What we basically need is a counter, which should be appended to the final line of the above code.

For example let us have a variable n, we start with n=1, and each time a scan happens this variable should increment by 1. And in the output, we use this variable in the file name.

For example, filename = out$n.tiff:

n =1 | filename = out1.tiff

n = n + 1

n = 2 | filename = out2.tiff

n = n + 1

n = 3 and so on…

We can have this variable within the script only, but since we are planning to use crontab, each time the script gets called, the variable will be initialized, and it will not do the function we intend it to do. For this we need to store variable outside the script, from where it will be called and will be written into. Some googling and landed on this site, which was very helpful to attain what I wanted to. Author says that he hasn’t found any use for the script, but I have 🙂 As explained in the site above this script is basically a counter, which creates a file nvalue. starting from n=0, values are written in this file, and each time the script is executed, this file with n=n+1 is updated.

So what I did is appended the above scanimage code to the ncounter script and the result looks something like this:

#!/bin/bash
nfilename="./nvalue"
n=0
touch $nfilename
. $nfilename
n=$(expr $n + 1)
echo "n=$n" > $nfilename
scanimage -x 80 -y 60 --resolution 600dpi --mode Color --format=tiff>out"$n".tiff

What this will attain is that every time this script is run, it will create a separate output file, depending on the value of n. We put these lines of code  in a file and call it time-lapse.sh

Now to run this file we need to make it executable, for this use:

$chmod +x time-lapse.sh

and to run the script:

$./time-lapse.sh

If  everything is right, you will get a file named out1.tiff as output, running the script again you will have out2.tiff as the output. Thus we have attained what we had wanted. Now everytime the script runs we get a new file, which was desired. With this the scanimage part is done, and now we come to the part where we are scheduling the scans. For this we use the crontab, which is a powerful tool for scheduling jobs. Some good and basic tutorials for crontab can be found here and here.

To edit your crontab use:

$crontab -e

If you are using crontab for the first time, it will ask for editor of choice which has nano, vi and emacs. For me emacs is the editor of choice.

So to run scans every 15 minutes my crontab looks like this:

# m h  dom mon dow   command
*/15 * * * * /home/yourusername/time-lapse.sh

And I had tough time when nothing was happenning with crontab. Though the script was running correctly in the terminal. So finally the tip of adding in the cronfile

SHELL=/bin/bash

solved the problem. But it took me some effort to land up on exact cause of the problem and in many places there were sermons on setting PATH and other things in the script but, I did not understand what they meant.

Okay, so far so good. Once you put this script in the crontab and keep the scanner connected, it will produce scans every 15 minutes. If you are scanning in colour at high resolution, make sure you have enough free disk space.

Once the scans have run for the time that you want them , lets say 3 days. You will have a bunch of files which are the time lapse images.  For this we use the ffmpeg and ImageMagick to help us out.

Dissent Is Treason

dissent-is-treason

The year Nineteen Eighty Four is long past us, in fact next year it will exactly 30 years in the past. But if we consider the dystopic vision of George Orwell from the novel, seems with each passing day we are approaching it with ever increasing pace. As if prophetically the Orwell thought about in the middle of last century are coming true. It is as if those in power are taking cues from Orwell’s books.Some famous lines from Nineteen Eighty Four  included the following:

War is Peace
Freedom is Slavery
Ignorance is Strength

And

Big Brother is Watching You

Two more individuals also told us something similar. One is a comic book writer and other is a paranoid hacker in the true sense of the word. Alan Moore in V for Vendetta tells us a story of not so distant future, which is very Orwellian. He says in an interview, it was idea in V, that there should be cameras on streets, which is what is implemented in London now. This is like an unintentional self-fulfiling prophecy. Though Alan Moore makes his case, it is after all a fictional story. Given that it might happen, but it is fiction. As is the case with Orwell’s works though fictional it has some real and frightening take home points, so is also with Alan Moore’s V for...

I will now come to the hacker. Richard M. Stallman, aka RMS aka Father of Free Software movement. Some of you might be surprised when I am making this claim. What does software have to do with dissent, or for that matter treason? But there are good reasons to make and substantiate this connection.

 

About the poster:

The idea behind this poster comes from Nineteen Eighty Four by George Orwell and current affairs in the world. Across the world it seems that any dissent against the government or those in power is seen as treason. Hence “Dissent Is Treason”This rhymes thematically very well with other in Orwells book which include “War is Peace. Freedom is slavery. Ignorance is strength.”
Similarly no matter how wrong the government is doing, however brutal they may be acting any voice of concern is treated as one would treat treason. The questioning of government and its actions which is essential in a healthy democracy is itself under attack.

In this poster the deer has one of its horns twisted in a way which is not normal. This “abnormal horn” metaphorically represents the view point which majority does not see or share. This can be concern for environment or disadvantaged groups, or against nexus of corporates and politicians. The list is endless. But any deer  with such a horn, will be shunned in deer society. Similarly in our society usually people who have points of view which conflict with powers to be are treated as traitors. Their acts of exposing the guilty as that of treason. But in fact such individuals are people with extraordinary courage. They include people like Julian Assange, Edward Snowden and countless others whom wedo not know but are thankful.

The deer image is from an old issue (c. 1870) of Journal Of Bombay Natural History Society.

Cost of environment

Former Finance Minister Yashwant Sinha on Tuesday blamed Congress leader and union minister Jairam Ramesh as being “singularly responsible for shaving off 2.5% of the GDP” by not giving environmental clearance to projects during his stint as the environment minister, escalating the war of words between the two.

via ET

Mr. Sinha should understand that economy is not everything. If at all protecting environment costs so much of GDP indirectly, even then it is okay. Perhaps we should provide 2.5% of GDP to protect our environment, and that would ensure it will remain for posterity.  The rampant rape of environment in form of various “developmental” projects and its toll on the flora and fauna is something that needs to be stopped. For example consider the illegal and legal mining in Goa and its impact on the fragile ecosystem there. Ramesh had a choice, and he exercised it. How many ministers do that? If the environment ministry will itself not worry about the environment then who will? Sinha in criticizing Ramesh seems to have forgotten this basic fact. Otherwise what is the reason for the Environment ministry to exist? For there are certain things that cannot be equalized in terms of money, and our flora and fauna is one of them. Mr. Sinha should understand that extinction is forever, no amount of money can bring back lost species or lost ecosystems. But people who are corrupted by lure of money at any cost (to environment and other people) will not understand this. Even if they do, their priorities are set by the bottom line, which is money.
