Article: In 1687, Isaac Newton published the Principia Mathematica, detailing two comprehensive and successful physical theories: Newton's laws of motion, which led to classical mechanics; and Newton's Law of Gravitation, which describes the fundamental force of gravity. The behavior of electricity and magnetism was studied by Faraday, Ohm, and others during the early 19th century. These studies led to the unification of the two phenomena into a single theory of electromagnetism, by James Clerk Maxwell (known as Maxwell's equations).

Question: What work was printed by Isaac Newton in 1687?
Ans: the Principia Mathematica


Here is a question about this article: In the early 1980s, a small but vocal segment of anthropologists and archaeologists attempted to demonstrate that contemporary groups usually identified as hunter-gatherers do not, in most cases, have a continuous history of hunting and gathering, and that in many cases their ancestors were agriculturalists and/or pastoralists[citation needed] who were pushed into marginal areas as a result of migrations, economic exploitation, and/or violent conflict (see, for example, the Kalahari Debate). The result of their effort has been the general acknowledgement that there has been complex interaction between hunter-gatherers and non-hunter-gatherers for millennia.[citation needed]
What is the answer to this question: What caused these one-time agriculturalists to become foragers??
****
So... pushed into marginal areas

Contact with European diseases such as smallpox and measles killed between 50 and 67 per cent of the Aboriginal population of North America in the first hundred years after the arrival of Europeans. Some 90 per cent of the native population near Massachusetts Bay Colony died of smallpox in an epidemic in 1617–1619. In 1633, in Plymouth, the Native Americans there were exposed to smallpox because of contact with Europeans. As it had done elsewhere, the virus wiped out entire population groups of Native Americans. It reached Lake Ontario in 1636, and the lands of the Iroquois by 1679. During the 1770s, smallpox killed at least 30% of the West Coast Native Americans. The 1775–82 North American smallpox epidemic and 1837 Great Plains smallpox epidemic brought devastation and drastic population depletion among the Plains Indians. In 1832, the federal government of the United States established a smallpox vaccination program for Native Americans (The Indian Vaccination Act of 1832).

What percent of the Aboriginal population of North America was killed in the first hundred years after first contact by smallpox and measles?
Answer: between 50 and 67 per cent


In early 1962 Nasser again attempted to wrest control of the military command from Amer. Amer responded by directly confronting Nasser for the first time and secretly rallying his loyalist officers. Nasser ultimately backed down, wary of a possible violent confrontation between the military and his civilian government. According to Boghdadi, the stress caused by the UAR's collapse and Amer's increasing autonomy forced Nasser, who already had diabetes, to practically live on painkillers from then on.
How did Nasser deal with the stress of the UAR's collapse and Amer's intransigence?
painkillers
