Answer:
Even though Egyptians didn't have any good technology at that time they would build pyramids by cutting and moving pieces of stones and making it into a pyramid shape. We still don't really know how they did their work but the stars were a guide for them to use as math and calculate where which of the pyramids corners would go.
(Hope this helps, I'm not so sure about the stars part but I saw it on a history channel a while ago. Good luck!)
Explanation:
At its core, the field of economics tries to uncover basic universal facts. Like many sciences, economics has a strong foundation in mathematics, and it is developed by testing hypotheses. In many ways, economics can be viewed as a field of applied psychology. Understanding how humans behave in certain situations and respond to changes is essential for the field's development.
Unlike the so-called "hard sciences," however, many economic hypotheses are difficult to test. Economic systems are run by governments, and it is immoral to cause economic harm to individuals and populations. With its strong mathematical foundation and its reliance on human behavior, economics straddles the gap between more basic types of science and so-called "soft sciences" such as anthropology and sociology.
In the media and in politics, however, the scientific aspects of the field are often ignored. Politicians might discuss the morality of different economic policies, and they might make promises based on faulty economic premises. Because economic policies have such a dramatic effect on the lives of voters, politicians spend a considerable amount of time developing a message that influences voters.
That statement is true.
