Optical illusions that fool the brain

October 17, 2013

What we see is when we look at something is not “sense data”.  It is not the pattern of photons of different wave lengths falling on the rods and cones of our eyes.  Something in our brains that is the equivalent of image processing software translates this raw data into an image that has meaning.

As my friend Bill Hickok said, that is why we can look at cartoons and see an image rather than just lines on a surface.  And that is why it is possible to fool the brain with optical illusions like the one above.

Optical illusions on the highway

August 28, 2010

Karanvir Singh Sangha, a student in Moga, India, posted some astonishing photos on his Karansangha’s Blog, of semi-trailers on European highways that are painted to look like what they’re not.

I don’t know what I’d think if I were driving down the road and saw one of these coming in the opposite direction.

Look at the photos to see what I mean.
