Optics principles. For example, the Ames room, Hering, Müller-Lyer, Orbison, Ponzo, Sander, and Wundt illusions all rely on the suggestion of the appearance of distance by using converging and diverging lines, in the same way that parallel light rays (or indeed any set of parallel lines) appear to converge at a vanishing point at infinity in two-dimensionally rendered images with artistic perspective. This suggestion is also responsible for the famous moon illusion where the moon, despite having essentially the same angular size, appears much larger near the horizon than it does at zenith. This illusion so confounded Ptolemy that he incorrectly
Point 5353 Point 5165, Point 5240 and Point 5100, guided their superior 155-millimetre Bofors howitzers with devastating accuracy. Pakistani troops on Point 5353 were first hit with smoke-filled mortar shells, to flush them out of their bunkers, and then with air-burst artillery, which showered down shards of metal at great speed. Well over 40 Pakistanis are believed to have died on Point 5353. Pakistan could not reinforce the troops since the Indian soldiers on Point 5165 and Point 5240 were in a position to hit their supply lines. Point 5353 Point 5353 (also called Point 17561, and Marpo La Peak) is a
