The most stunnning illusion EVER

I am sure we have all seen numerous illusions but this one so darn stunning that I literally let out a shriek seeing this one.

Look at squares A and B. They are the same shade of gray. I am sure you wont believe this, I didn't, well take a printout, cut it into 4 pieces, take the squares A & B side by side and see for yourself. Lazier ones can use mspaint/gimp to see the magic.

Brightness and color can have powerful effects on perception. In this illusion created by vision scientist Edward H. Adelson of the Massachusetts Institute of Technology. Our brain does not perceive the true brightness and color of each square but instead determines the brightness and color of A and B by comparison with the squares surrounding them

Edward de Bono and String Theory

Every now and then I am sure we hear of analogies that seem to make absolutely no co-relation to the topic of discussion to anyone other than the analogizer [;)]. I once had a friend, lets call her XXX who used to boil down allllllll things known to mankind to a sambar wada problem [XXX if you are reading this, I am not talking about you, its about some other friend who has that sameproblem interesting habit ;)]. We have a long interview process for a candidate and we sit together to decide if the candidate is the right choice. She goes - "He is an idliwala and we want to make samosas!". We have a week long sales meeting trying to see if a product makes sense for India market, she says: "We are trying to sell idli in Chandni Chowk" [which in all probabilities meant that its not going to sell ;)]. I could go and on with how everything from string theory to making tea can all boil down to idli sambhar problem but then it wont leave anything for your imaginations :). It sometimes gets entertaining to watch an analogizer stretch his analogy thin to demonstrate that indeed it does make sense.

The other day in a casual office chat AR says "Retail business is like doctors". No worries... I didn't make head or tail of it either [however if you did, read on to make sure that you got it right and if you DID get it right, Hats off to you for the lateral thoughts (as an aside, the same AR just helped me remember the phrase "lateral thinking" by asking me to google Edward de Bono!)]. Anyways, what he meant to say was that professionally unless you are well known as a Doctor or a Retailer, you dont make a lot of money. He went on to explain the analogy; A small retailer cannot make a lot of profit unless people know him, at which point he can go on to charge a premium for the stuff he has, a smaller retailer needs to offer the stuff at the lowest price he can afford to attract customers. NOW do you see the analogy? Well.. honestly I dont :) :)

On the brighter side however, these analogies truly show how wonderfully human mind works. Relating two seemingly very different things to better understand the problem at hand, to see a pattern in the chaos is a quality of a beautiful mind.

PS: If you are thinking how the image of the brain relates to the post. Well.. Its not about relativity.. is it?
