Definition of science:

• English: sciences that use math as a language. Exact sciences (physics, chemistry)
• Spanish: a system of knowledge and specialization of knowledge (there is theological science, ethical science, etc).

The reason for this is that english comes from more languages than the rest of Europe. English comes from germanic and latin. 

Also because the people on the continental side of Europe were more into humanities, while the British were more into exact sciences. 

Episteme: knowledge that is certain. A greek word that was the first definition of science. 

The english term of science arises after the scientific revolution, the Copernican Revolution, in the 16th century. 

Ptolemy´s solar system (reasons):

• common sense, the sun appears to revolve around us. 
• the Earth was the heaviest thing in the sky because it was made of matter, so it had to be at the center.  
• The stars seem fixed, in the sense that the relation to one another is always the same. 
• The only disorderly object in the heavens were the planets because they never stayed still, they were "Wanderers".

From this they reached the conclusion that everything in the heavens moved in circles, because they are eternal and perfect.
Plato reaches the conclusion that everything in the heavens is eternal and perfect, a circle.
