According to Zoroastrian tradition, a dead body is unclean and must be disposed of in a safe manner. To prevent the pollution of earth or fire, dead bodies are placed atop a tower, where they are exposed to the sun and birds of prey. The towers are circular raised structures with nearly flat roofs that are divided into three concentric rings; one ring is designated for the bodies of men, one for women, and one for children. Who coined the term "tower of silence"?

Luna 5 was an unmanned Soviet spacecraft designed to continue investigations of a lunar soft landing. On May 10, the spacecraft began spinning around its main axis due to a problem in a flotation gyroscope in the I-100 guidance system unit.

What was the first?

Florence Nightingale is considered the founder of modern nursing. She organized a unit of 38 women nurses in 1854 for service in the Crimean War, and, by the end of the war, her intense efforts had made her a legend. With the testimonial fund collected for her war services, she established the Nightingale School and Home for training nurses at St. Thomas's Hospital in London. Why was Nightingale called "The Lady with the Lamp"?
