                           navigate the Earth 

150 BC           It is clear that a special 
                           chain of Greek 
                           scientists had evolved 
                           a concept of the solar 
                           system. It seems almost 
                           equally clear that 
                           between 200BC and
                           200 AD a deliberately
                           planned policy of the 
                           combined political and
                           religious powers under-
                           took the conditioning of 
                           the human reflexes to 
                           misconceive, mis-see,
                           or mostly not see at all
                           the macro-micro 
                           systems in which we 
                           live
                           Their success drew the
                           curtains on science for 
                           1700 years—until 1500
