'...All my best memories come back lively to me
Some can even make me cry
Just like before; It's yesterday once more
Every 'Sha-la-la-la' every 'vou-ou-vo-vou' still shine
Every 'Shin'-a lin'-a lin' ' let they starting to sing so high...'SCIENCE IN EVERYDAY LIFE book 3 (1959)

'...A block (when being tilted gradually) topples over when the vertical line from its centre of gravity passes outside its base...
...The lower the c.g. of an object and the larger its base, the less likelihood there is of its being knocked over...'

'...If the source of light is larger than the opaque body, the size of the shadow obtained depends on the position of the screen (on which the shadow is falling). As the screen is moved away from the opaque body, the 'umbra' (the darker inner portion of the shadow) decreases in size while the 'penumbra' (the fainter outer portion) increases in size...'

'...Make two black spots by side on a sheet of white paper so that they're separated by a distance of 55 millimeters. Close the left eye and look at the left dot with your right eye. Hold the paper at a distance of about 30 cms and move it slowly towards you. At a distance of about 10 cms from your open eye, the right dot will suddenly disappear. This's because its image has fallen on the blind spot of your eye which as you know, is insensitive to light impressions. (Nerve fibres from all parts of the retina collect here to form the optic nerve which transmits light impressions to the brain.)
