Read the following excerpt from ball's chapter on ptolemy in great astronomers. imagine a fixed arm to extend from the earth to the sun, as shown in the accompanying figure, then this arm will move round uniformly, in consequence of the sun's movement. at a point p on this arm let a small circle be described. venus is supposed to revolve uniformly in this small circle, while the circle itself is carried round continuously by the movement of the sun. in this way it was possible to account for the chief peculiarities in the movement of venus. it will be seen that, in consequence of the revolution around p, the spectator on the earth will sometimes see venus on one side of the sun, and sometimes on the other side, so that the planet always remains in the sun's vicinity. by properly proportioning the movements, this little contrivance simulated the transitions from the morning star to the evening star. now, evaluate the image that accompanied that text. compare the information in the excerpt to the diagram. what information from each the reader to understand ptolemy’s theory of how planets move? how do the excerpt and diagram complement one another? ?

According to Ptolemy’s theory, Earth was at the center of the solar system. To a modern-day reader, this theory will make no sense because it’s well established that the sun is the center of the solar system. This diagram helps the reader picture what Ptolemy’s theory is all about.

The text describes the movement of the sun and the planets around Earth based on Ptolemy’s theory. The diagram aids in the reader’s understanding of the text; it clearly shows the ideas Ptolemy proposed. Earth is shown at the center, and the sun and the planet Venus are shown circling around Earth. Venus is also shown making a circular motion around a point on its path around Earth. Using this diagram, Ptolemy explained the movement of Venus across Earth’s sky from morning to evening and the reason Venus sometimes appears on one side of the sun and sometimes on the other.

Explanation:

This is the direct answer from Plato. I hope that this was helpful to you, please like and rate my answer if it was! :)

the author is showing that it is the insatisfaction of basic needs that brings about the protests such as the strikes.if workers do not earn enough to buy food and feed their families and themselves in order to continue working, what is the use of working? besides, another message from the author is that of the owners of factories should be worried about ensuring their furure by having a second and third generation of workers in their industries.if they do not hear the workers demands, they will not have any more workers to make their pockets full.
