Why does the theory of heliocentrism overcome the problem of wandering stars?
In the old geocentric system, in which people believed what they could OBVIOUSLY see - that the Earth was standing still and the Sun, Moon and stars traveled around the Earth - everything in the sky was fine. Well, not quite; there were five things in the sky that did not behave the way they were supposed to. Those five things were "wanderers", or in the Greek, "planets". They did NOT move with the stars, the way the stars always moved. These five planets - which we now call Mercury, Venus, Mars, Jupiter and Saturn - "wandered" around the sky! Sometimes the moved quickly, sometimes slowly, and sometimes backwards from the way all the other stars behaved! Aristotle, the Greek philosopher, believed that everything moved in circles, that the Earth - Athens, in fact - was the center of everything, and that everything had its own unique "nature", and that no good could come from trying to figure out any grand principles of the universe. However, by claiming this he single-handedly stunted the development of western civilization for a thousand years. For 13 centuries after him, his pronouncements were universally accepted as truth, even though he seems to have been in error about EVERYTHING he said. So for 13 centuries after Aristotle said that EVERYTHING traveled in circles, astronomers and mathematicians tried to reconcile their observations with the Aristolean notion of circles. (Hipparchus had proposed the heliocentric concept around 130BC.) Circles within circles, or "epicycles", were one of the concepts that tried to interpret the more-and-more accurate measurements of the heavens. It finally fell to Nicolas Copernicus to broadly state the heliocentric theory, and to Johanne Keppler to propose that the planets moved in elliptical orbits rather than circular ones.
Who thought that planets moved in little circles which moved in bigger circle?
Galieo Gallie
Who believed that planets moved in ellipses?
The first person to do this was Kepler.
Galileo was forced to do what?
galileo was forced to stop studying astronomy after his claim that the earth moved round the sun. He was correct of course but this went against the christian teachings at the time as they believed that everything revolved around the earth
What did Copernicus claim?
He thought that everything moved around the sun

Who thought that planets moved in little circles which moved in bigger circle?
Galieo Gallie
Why did early astronomers believe the geocentric model was true?
Because they thought that planets moved on little circles that moved on bigger circles, and they didnt have modern technology like other astronomers had
Why did Plato assume that the movement of the planets were along circles?
He was certain that all planets moved in a uniform, orderly manner, and his contemporaries figured that meant it had to be in circles because in circles there is no beginning and no end.
Who believed air moved objects along?
Aristotle

galileo was forced to stop studying astronomy after his claim that the earth moved round the sun. He was correct of course but this went against the christian teachings at the time as they believed that everything revolved around the earth
What was Aristotle's law of motion?
Aristotle believed v = k(F/R) where speed is proportional to motive force, and inversely proportional to resistance.
What did Copernicus claim?
He thought that everything moved around the sun
With who moved from Mecca to Medina Muhammad?
His family and those few that believed and trusted in him
What geometric shape did the ancients used to describe motions of the planats?
The ancients assumed that everything moved in circles. Since that didn't work very well, they assumed that the motion was in circles-within-circles, called "epicycles". That was close enough given their generally crummy measuring devices. By the 1500's, measuring devices had become accurate enough to see that planets didn't move in epicycles either. Johanes Kepler determined that the planets move in ELLIPTICAL orbits, and we have since learned that all orbits are always elliptical.
6. What is believed to be the evolutionary origin of mitochondria?
A bacteria that moved into a cell and stayed alive.
