In sfarsit stim cum functioneaza gravitatia!

Pentru ca daca ar fi fost orbite circulare, modelul necesita mai multe bucle decat modelul lui Ptolemeu. Pare simplu cand il privesti asa dar in realitate este mai complicat decat este cel din antichitate.

"However, Copernicus also used circular orbits and had to resort to epicycles and deferents to explain retrograde motions. In fact, Copernicus was forced to use more epicycles than Ptolemy, i.e. a more complicated system of circles on circles. Thus, Copernicus' model would have failed our modern criteria that a scientific model be as simple as possible (Occam's Razor)."




Cine te-a suparat Adrian ? :)

Nu cine, ce. Fanatismul.
