What is Coperican theory ?​

History
1 answer:
labwork [276]2 years ago
4 0
Copernican heliocentrism is the name given to the astronomical model developed by Nicolaus Copernicus and published in 1543. This model positioned the Sun at the center of the Universe, motionless, with Earth and the other planets orbiting around it in circular paths, modified by epicycles, and at uniform speeds.

The major features of Copernican theory are: Heavenly motions are uniform, eternal, and circular or compounded of several circles (epicycles). The center of the universe is near the Sun. Around the Sun, in order, are Mercury, Venus, the Earth and Moon, Mars, Jupiter, Saturn, and the fixed stars.

Allows calculation of planetary orbital periods around Sun. Allows geometric calculations of planetary distances from Sun. These show nice regularity: more distant planets have longer periods, move slower. Easier to calculate planetary positions than with Ptolemaic model.

I hope this helps!

How did the government of Rome develop into an Empire
Alekssandra [29.7K]
Rome was initially a city-state with about 50 square miles of territory to sustain itself. With small farms, the citizens could not split them up between their sons and so sought extra land for them. The surrounding city-states were bent on the same need, so they clashed, with Romme losing some, but on average winning most fights. As winners they took land and expanded. 

<span>This expansion created more strife, and expansion, leading to dominance of Italy. As a rising power, cities in southern Gaul (France), Spain and Sicily sought Rome's assistance, and as a land power it allied itself with Carthage, a sea power. This arrangement came to an end when Rome supported Greek cities in Sicily against Carthaginian encroachment. A win in the First Punic (Carthaginian) War put the Romans on the path to empire, which was consilidated with the extirmination of Carthage in the Third Punic War in 146 BCE. At this stage Rome dominated the Western Mediterranean. </span>

What steps did the Nazis take to ensure that students were being taught properly?
sesenic [268]

Hitler took great trouble to make sure that young people were loyal to him and the Nazi Party. He realized that in the future he may have to call on these people to put up with hardships, to fight and perhaps die for him. Therefore, it was important for young people to think that Hitler and the Nazis were the best thing that had ever happened to Germany.

Youngsters were indoctrinated (brainwashed) to think like the Nazis. Textbooks were rewritten to get across the Nazi message. Children were also taught to recognize Jews at a glance.
