" Sharpen your brain" Teacher shouts. I keep wondering which sharpner to use either the red one or the blue one. Both of them do not fit my head.
              God has given us beautiful eyes. We never know the amount of calculation getting done for every image we see. Eye infact eyes captures the image, and sends the signal to brain. No one ever knows what these signals are yet.  This would definitely contain the logic of what normal CRT or display screens does. Nobody knows how the brain processes the visual signals from eyes..it should be similar to as we process pixel signals. So eyes should be sending the pixel details like luminance and chrominance values. that is the intensity of brightness of image and color of image must be sent from eyes to brain. We never know what type of compression is getting used. Eye has job to maintain proper contrast by keeping a proper gamma corrected value. So brain has to produce an perception of image given these details.  These images details are collected behind our retina, therefore brain has to invert the image and produce the correct perception. Not only this brain has additional functionality of suggregating the images from the two eyes into one continuous image. Wow..so much of processing and we never feel the pain of such calculation.
            Taking another example, If my toe gets hurt, neurons from the toe carry the signal to brain. The brain takes the action of sending the anti bodies to the portion which is hurt meanwhile it alerts me. I can feel pain in the exact location. How good it would be if you avert brain from alerting you. May be this what the pain killers are doing. Need some more investigation in this regard.
             In fact everyone has a wonderful brain, which is sharp quick and what not but keeps innocent.


              "You should come out as flying colors" another teacher says. Something which comes out with flying colors. I could imagine colorful butterflies coming out of their pupa. Is he referring to butterfly may be yes...These flying colors do not fly high as high as I want to be. Anyway every butterfly which comes out has different color and texture. Everyone comes out with flying colors.  Different butterflies fly at different heights but all are flying at their best heights :)..
