# 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)

# Heaven and Hell

Circle Limit IV
Heaven and Hell
by M C Escher
Yesterday I have put up Escher’s Circle Limit IV – Heaven and Hell on my new desk. The Circle Limit series of drawings was drawn by Escher are essentially what are known as his hyperbolic tesselations. The new computer table that I have got has an odd shape. On one end the side is circular and it smoothly metamorphises into rectangle on the other side. Though it is not at all comparable to what Escher has accomplished, I feel bad even when I use the word metamorphosis for this, but I have not found anything better. The table is designed for use with a desktop. So it has sections for different parts of the desktop like the monitor, CPU keyboard etc.
Anyways the main point that I want to tell is that the table at one end is circular. Since I had put Escher’s Three World on another table, I thought it would be a good idea to use a ciruclar print of Escher for this part of the table. Of all the prints I had, which I had taken when I had at my disposal A3 sized printers, the one which fitted the purpose seemed to be Circle Limit IV – Heaven and Hell.
Let us see what Escher himself has to say about this series of works viz. The Circle Limits:
So far four examples have been shown with points as limits of infinite smallness. A diminution in the size of the figures progressing in the opposite direction, i.e. from within outwards, leads to more satisfying results. The limit is no longer a point, but a line which border’s the whole complex and gives it a logical boundary. In this way one creates, as it were, a universe, a geometrical enclosure. If the progressive reduction in size radiates in all directions at an equal rate, then the limit becomes a circle. [1]
And he says this about Heaven and Hell:
CIRCLE LIMIT IV, (Heaven and Hell)
Here also we have the components diminishing in size as they move outwards. The six largest (three white angels and three black devils) are arranged about the centre and radiate from it. The disc is divided into six sections in which, turn and turn about, the angels on a black background and then the devils on a white one, gain the upper hand. in this way, heaven and hell change place six times. In the intermediate, “earthly” stages, they are equivalent. [1]
Like most of Escher’s drawings this one also takes you to a different world. A world which is far away from the reality. A world of mathematics. A world of abstraction. But then as always we can make connections between this abstract world and the real world. The connections that we can make are dependent on the world view that we have. Some people fail to make the connection. They cannot see’.
The Circle Limit series is what brought Escher to the eyes of the mathematicians. H. S. M. Coxeter used Circle Limit II as an illustration in his article on hyperbolic tesselations. Since then the other works of Escher have been examined by the mathematicians, and we find that very deep and fundamental ideaso of mathematics are embedded in them. As to how Escher did it is amazing. The kind of clear insight that Escher exhibits in his artwork is astounding. He could visualize the mathematical transformations in his head and then transform them onto the artwork he was working with. Escher has said
I have brought to light only one percent of what I have seen in the darkness. [2]
This must be certainly true, as most of his artwork is nowhere close to what we see in the light. I rate the artwork of Escher as greater than that of the renessaince artist’s as they had just beautifully drawn what one could “see.” But with Escher we go a step beyond, imagination takes the control. What interests me in Escher is that he can make you imagine the unimaginable. What you know is not possible is demonstrated just in front of your eyes. Logic is discarded. Rather it is kept in the basement which is upstairs for Escher.
Yesterday you start to believe what you thought was impossible tommorow.
The way different things merge for Escher is just unparalled in the work of other artists. What has now become known as “Escheresque” is just the typical of his style. Lot of later artists are influenced by the works of Escher, I have found one Istvaan Orosz particulary good. There are others who are equally good but I don’t remember their names now….
Coming back to Heaven and Hell. The main artwork is in a woodcut format in black and white. For me this is a kind of dyad which represents the world. The idea of two opposing forces one termed to be evil and the other good are all permeating in the Universe. Here also the bat-devils and the angels are the representative of the same. There is no part of the Universe where these two are not present. It might seem that somewhere far out there there is nothing, but it is not so. Even there, the design is the same, it is just too far for us to see. This is what harmony in the universe is about. It is the same everywhere, when you have a broad enough world-view. The cosmologists say that the Universe is homogenous and isotropic, if you choose to “see” it at the right scale. The cosmologists often use Heaven and Hell to illustrate this point. For me introduction to Escher came in a talk by a cosmologist who used The Waterfall to illustrate the idea of a perpetual motion machine. Since then I have become addicted to Escher, as has everybody else who has some sense of imagination. For those who cannot appreciate Escher, I can just pity at their miserable imagination.

# The Demarcation Problem

What is the demarcation problem?
I want to discuss an acute problem which philosophers of science have to face. The question it self is quite simple. You don’t have to be genius to understand the question, but the answer to this question is far from simple.
The question put simply would read something like this:
What is the difference between science and non-science?
Or
What is science?
If you ask this question perhaps to a school going kid, you will probably get a good and clear cut answer, Physics, Chemistry and Biology are sciences, [also perhaps mathematics also?]. Also the
perhaps this is the view not only school going kids but their teachers also feel and so do practicing scientists.
Most of the lay people are afraid of science and scientists. The very idea of science is mystical and scientists are seen as the worshippers of the nature itself. This is the common image which is also portrayed in the media, [so it is popular or it is the other way round?]. In the movies scientists are [if they are not the protagonists] shown as causing almost the end of the world, or having no hearts but for the subject of their study. This is the label of evil genius which has been put on them. The list of examples would be endless. But to give a few of my own favorite ones are as under:
Uma Thurman as Poison Ivy in Batman and Robin

And Mike Myers as Dr. Evil in the Austin Powers series

This can be easily seen that the public opinion about science is not what can be called good. Another thing to add here, if we in general see that there is an attribute scientific to any thing then the thing is has to be rational, logical and something that can be relied upon. Take for example the warning which every cigarette smoker reads but ignores, this warning is supposed to be scientific’ so that you have to take it seriously, no bullshit here, this is what scientists say. This is The Truth, with a capital T. All these concepts are what I call the traditional concepts in Philosophy of Science [PoS hereafter], have a root in the beginning of the 20th century.
What is the point of bringing all this up in an philosophical discussion? Wait, what we will see is the fact that the things just mentioned have a very deep root in philosophy. What we want to do is to explicate this root.
We start our discussion with the so called modern era of the philosophy, which was mostly in the last century. In this era a group of philosophers known as the Vienna Circle presented the first dominant view point, which persisted till the first half of the century.
But this will be in another post….
