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 Copernican model displaced the geocentric model of Ptolemy that had prevailed for centuries, which had placed Earth at the center of the Universe. Copernican heliocentrism is often regarded[by whom?] as the launching point to modern astronomy and the Scientific Revolution.
Heliocentric model from Nicolaus Copernicus' De revolutionibus orbium coelestium (On the Revolutions of the Heavenly Spheres)
Although he had circulated an outline of his own heliocentric theory to colleagues sometime before 1514, he did not decide to publish it until he was urged to do so late in his life by his pupil Rheticus. Copernicus's challenge was to present a practical alternative to the Ptolemaic model by more elegantly and accurately determining the length of a solar year while preserving the metaphysical implications of a mathematically ordered cosmos. Thus, his heliocentric model retained several of the Ptolemaic elements, causing inaccuracies such as the planets' circular orbits, epicycles, and uniform speeds,[1] while at the same time introducing such innovative ideas as:-
The Earth is one of several planets revolving around a stationary sun in a determined order.
The Earth has three motions: daily rotation, annual revolution, and annual tilting of its axis.
Retrograde motion of the planets is explained by the Earth's motion.
The distance from the Earth to the Sun is small compared to the distance from the Sun to the stars.

The correct answer is turning point for the way the laws of colonial Virginia distinguished people of different races
In 1676, one hundred years before the declaration of independence, the state of Virginia was the scene of the so-called Bacon Rebellion, in which landowners, slaves and servants came together, and which can only be stifled with the dispatch of English troops. It began as a product of the demand of the wealthy landowner Nathaniel Bacon, whose properties were located in the border area, for a more effective war policy against "the Indian". This demand to local authorities extended to the denunciation of an unfair tax policy, the arbitrary distribution of public offices and the lack of protection for farmers against the indigenous threat, in “a mixture of populist resentment against the rich and border hatred against the Indians ”. (Apart from the huge historical-social distances, we could say that it is similar to a Trump that today rages against the political and economic establishment while agitating a strongly xenophobic and anti-immigrant program).
The significance of this rebellion was that it brought together a heterogeneous social spectrum, attracting the dissatisfaction of slaves and servants against their living conditions, showing a potentially dangerous social union. In addition to the problem of indigenous hostility and the danger of slave revolts, the colonial elite had to do with the class anger of the poor whites - the servants, the tenants, the urban poor, the landless, the taxpayers, soldiers and sailors. In fact, after the Bacon Rebellion in 1760, "eighteen new attempts were made to overthrow the colonial governments and eight black revolts in South Carolina and New York." (The Other History of the United States). In this context, racism was the preferred ideological artifact used by the dominant classes to prevent the development of these social ties. But under the strong fiscal pressure that ensued the wars waged by England, which increased poverty in the lower strata and affected sectors of the local elites, they began to defend nationalist ideals as a way to monopolize the extraction of resources while unleashing potential rebellions. depending on national unity.

Mazu has these powers because She was no longer an ordinary girl, the gods had touched her.
Explanation:
What had occupied mazu's mind initially was the act of weaving till her mind became peaceful and still. She had sat down to weave because she was worried for her fishermen brothers who were outside in the water.
