The only object ever aimed at in those days was to prepare tables for predicting
the places of the planets . It was not a mechanical problem ; there was no notion
of a governing law of forces . From this time onwards all interest in astronomy ...

Grant has shown the values of some of these as given by observation in the
tables of Meyer and more modern tables , and has compared them with the

its position . These worked well enough for a time , but at last the differences
between the calculated and observed longitudes of the planet became serious .
