it was know in ancient times that Venus passes between the Earth and the Sun, and Copernicus had a model which had the Sun at the centre, so in his model Venus was closer to the centre, thus an inferior planet by definition.

copernicus :) =))))
The mechanical model (gears and the like) of Copernicus is much easier to make than Ptolemy's.
The difference between a map and a model is a model is three dimensional and a map is two dimensional (flat) . In another sense, there is no difference. A model is just one kind of map.
Copernicus's system used circles and epicycles, just like the ancient Ptolemaic system, with the difference that by placing the Sun at the centre Copernicus could simplify the complicated paths taken by the planets through space. Kepler had the advantage of new accurate observations made by Tycho Brahe at the end of the 16th century, and these enabled Kepler to realise that by using elliptical orbits for the planets, the modelled positions could be fitted more closely with the measured positions. Kepler retained the idea of having the Sun at the centre and it is the model used today with slight modifications from Einstein's theory of relativity.
because i say so!
what is the difference between the memory store model and the working memory model?

difference between holistic and medical models
Copernicus
it was know in ancient times that Venus passes between the Earth and the Sun, and Copernicus had a model which had the Sun at the centre, so in his model Venus was closer to the centre, thus an inferior planet by definition. That was in about 1560.

Nicolaus Copernicus.
