Can heartbeat restart spontaneously after death?
Death occurs when the person is without the functions of their brain (Some brain cells live on,meaning the brain didnt "die"). Prior to that, the person is not dead, regardless of what the heart is doing. If they are not dead, the heart is not restarting after death, but may continue to beat if the nerves send their last messages after death to the heart. It can happen. But its extremely unlikely.

When an image hits the retina the image is upside down what flips the image the right way round?
Light hitting the lens the eye is refracted. Imagine a bunch of drinking straws tied at the middle. If you fan out the top the bottom of the straws will fan in the opposite direction. So it is with the light through a lens. The angle of incidence bends all the light through the centre of the lens and out of the back of the lens. As light always travels in straight lines through a medium, that which was at the bottom on the way in is at the top on the way out and that which was on the left finishes up on the right. Therefore the image is upside down.
