It's fascinating to know that the Human Brain knows how to carry out different scientific processes from birth even though we consciously neither feel it nor understand it unless we are taught about it.

For Instance-

1)Our Brain knows from birth that it has to invert the image formed in the retina to get the actual image but we know it only when we get to Higher classes.

2)The Brain projects back the light rays that form the image at the retina in a straight line to know the Light Source even though 'we' don't know initially that light travels in straight line.
