Vacation Until Friday
Blogging may be non-existent until Friday as our family will be on the beach in Norfolk Virginia.
I will leave you with the coolest optical illusion that I have ever seen. Here is photo from Marginal Revolution:
Will Franklin of Willisms thought, (like I did), that this could not be real. He did some excellent photoshop work to prove that, indeed squares A and B are the same shade of gray:
The point of this illusion is to try to convince you that intuition can only get you so far. Sometimes you need to question it.

Hi Vikram
Thank you, I hope we have a very relaxing time.
This is the first time I put photos in my blog. It wasn't too difficult.

Have a nice vacation Michael!
I still can 't believe they are the same shade. It's amazing how our eye/intuition fails us.

Saw that illusion in a book recently (was it Gladwell's Blink?) and had a hard time believing it - but the Photoshopping makes it startlingly clear.
Happy trip!

Patrix: I woke up at 5:00 am and all I could think about was checking blogs. But I'm not compulsive...am I?

A wonderful example of how our brain perceives shades and colors.
But, if it were a REAL chessboard and there was a REAL shadow being cast by the cylinder, than in real life the two squares would be different colors.
Our braind is perceiving the reality that the illustration is presenting, and not the actual shades of the boxes.

Hi Half Sigma
Indeed, the illusion works on the fact that our brains make inferences based on experience. What stikes you though is the magnitude of this illusion. At first glance, you cannot even believe that these are the same shade.

That's an awesome illusion. Loved how the two look so different from each other and yet, they are the same.
Good find!
