The Incredible Human Eye

-
Image
The average human retina has five million cone receptors on it. Since the cones are responsible for colour vision, you might suppose that this equates to a five megapixel equivalent for the human eye. But there are also a hundred million rods that detect monochrome contrast, which plays an important role in the sharpness of the image you see. And even this 105MP is an underestimate because the eye is not a still camera. You have two eyes (no kidding!) and they continually flick around to cover a much larger area than your field of view and the composite image is assembled in the brain - not unlike stitching together a panoramic photo. In good light, you can distinguish two fine lines if they are separate by at least 0.6 arc-minutes (0.01.Degrees). This gives an equivalent pixel size of 0.3 arc-minutes. If you take a conservative 120 degrees as your horizontal field of view and 60 degrees in the vertical plane, this translates to 576 megapixels of available image data. Curiously ...

The logics and reasons behind Left hand drive and Right hand drive

-

Research in 1969 by  J. J. Leeming  showed that countries driving on the left have a lower collision rate than countries driving on the right. Logic:   It has been suggested that this is partly because humans are more commonly  right-eye dominant  than left-eye dominant.  In left-hand traffic, the predominantly better-performing right eye is used to monitor oncoming traffic and the driver's  wing mirror  (side mirror). in an RHD car (that drives on the left) with manual transmission, the driver has the right hand, which for most people is dominant, on the steering wheel at all times and uses the left hand (and left foot) to change gears. So it seems driving on the left is safer, but is it natural? yes it is as we know that Cyclists, motorcyclists and horse riders typically mount from the left-hand side, with motorcycle side stands almost always located on the left. So it is natural for a  passenger  to sit in a car from left...
