Optical spiral!


Out of the many optical illusions I have had the honour to see through books, stumbleupon, mails, t-shirts and all the other places they have found home, I like this one the best for a single reason. The others cause a slight optical illusion, I mean if you know that the two circles are equal , or the crooked lines are really same...then you can easily convince yourself that they are.This one is different.

Try convincing yourself that the orange spirals are really not spirals but circles. Cannot do it right?Oof course you cannot because they are really spirals.

Anyways how about convincing yourself that the blue and the green spirals which you see, are actually of same colour! :)

Hint: After you have tried to look with one eye, two eyes, three eyes...printed it , inverted it...and done all sorts of things with it, try the colour picker in paint. Start>Accessories>paint>coloupicker!

The ' What if ? ' illusion

As humans, our mere ability to think 'What if?' makes us believe that we are in control. But do we really change things, do we affect the reality. If we do , to what degree? It is said that if a butterfly makes an extra flap of its wings, the reality can change so much so that after a decade a nonexistent cyclone can result.Is it really true? Even if it is, does the butterfly really have a control enough to make that extra flap? Is it really free will or an illusion of free will? A very fascinating example is seen in first person games like Prince of Persia or God of wars and so on.The game makers try hard to give the gamers a feeling that they can do anything in that virtual world. The game programmers know very well though that they can program only a limited number of options. There cannot be more than a finite number of stimulus- response pairs that they would have programmed. Even then, while we play the game we feel that we are in complete control (at least that is the ai

IIM Ahmedabad interview

14th March 2010, IIFT Delhi Morning 8:45 exactly around 28 call getters were divided into 4 panels .Then we were called in for writing our essays. In ten minutes we were supposed to write an essay on "Is banning politicians with criminal records from contesting election violation of their rights?". At first I felt it was a bouncer, so I only had two choices, either duck down and give up or hook. I could not have played a defensive shot. It was a bouncer because I had to be sure that I don't mention any random political proper nouns in the essay which i could be questioned upon later in the interview. so very carefully i put forward two points, in a fairly structured way. Firstly, that in india politicians are looked upon as leaders, and there is a need of immaculate integrity at the top.Secondly, if thousands of citizens' rights are at stake, we can forgo a chance of violating one politician's rights and if he is a true servant, he won't mind it. I thoug
