The image in a camera obscura is flipped upside down because light travels in straight lines from its source. The earliest mention of the principles behind the camera obscura belongs to Mozi (c. 468-376 BC), a Chinese philosopher. 2) TOP 500 It is a project that ranks and gives detailed accounts of the 500 most powerful computer systems in the world.
