Answer:
Muhammad's first revelation was an event described in Islamic tradition as taking place in 610 AD, during which the Islamic prophet, Muhammad was visited by the angel Jibrīl, known as Gabriel in English, who revealed to him the beginnings of what would later become the Qur'an.
Explanation:
Belief in the supernatural-and specifically in the devil's practice of giving certain humans (witches) the power to harm others in return for their loyalty-had emerged in Europe as early as the 14th century, and was widespread in colonial New England. In addition, the harsh realities of life in the rural Puritan community of Salem Village (present-day Danvers, Massachusetts) at the time included the after-effects of a British war with France in the American colonies in 1689, a recent smallpox epidemic, fears of attacks from neighboring Native American tribes and a longstanding rivalry with the more affluent community of Salem Town (present-day Salem). Amid these simmering tensions, the Salem witch trials would be
fueled by residents' suspicions of and resentment toward their neighbors, as well as their fear of outsiders.
Malaria
Dr. John Gorrie practiced medicine in Florida. He experimented with ways to prevent the spread of malaria. The summer of 1841 was a particularly bad summer for malaria infection. People had not yet realized that malaria was spread by mosquitoes. (That discovery didn't occur till the 1890s.) Dr. Gorrie, noting that malaria was unlikely to occur in colder climates, thought that perhaps cooling the air in the sick rooms of his patients could help them. He started with the idea of using a fan to blow air across a bucket of ice. A rudimentary beginning to air cooling and refrigeration ... but as they say, the rest is history!
Technology is created to help make our lives daily tasks easier. If you are to cut wood, you would cut it with a hatchet, and not try to break it with your bare hand, for example.
hope this helps
