WORLD CIVILIZATION

Detailed explanation-1: -The Babylonians were the first to recognize that astronomical phenomena are periodic and apply mathematics to their predictions. Tablets dating back to the Old Babylonian period document the application of mathematics to the variation in the length of daylight over a solar year.

Detailed explanation-2: -This research suggested that the gardens were laid out on a sloping construct designed to imitate a natural mountain landscape and were watered by a novel system of irrigation, perhaps making early use of what would eventually be known as the Archimedes screw.

Detailed explanation-3: -The astronomers of Babylonia, scratching tiny marks in soft clay, used surprisingly sophisticated geometry to calculate the orbit of what they called the White Star–the planet Jupiter. These tablets are quite incomprehensible to the untrained eye.

Detailed explanation-4: -Babylonian king Nebuchadnezzar II was said to have constructed the luxurious Hanging Gardens in the sixth century B.C. as a gift to his wife, Amytis, who was homesick for the beautiful vegetation and mountains of her native Media (the northwestern part of modern-day Iran).
