Tirohia te wāhanga i raro nei, kātahi ka whakautu i te pātai i muri mai i te reo kotahi me te wāhanga:  Passage: He whakaahuatanga tenei mo te planetarium, orrery ranei. I kii a Pappus o Alexandria kua tuhia e Archimedes tetahi tuhinga (kua ngaro inaianei) mo te hanganga o enei tikanga e kiia ana ko On Sphere-Making. Ko te rangahau o nāianei i tēnei wāhi kua arotahi ki te tikanga Antikythera, tētahi atu pūrere i hangaia i te 100 BC i hangaia pea mo te take kotahi. Ko te hanga i ngā tikanga o tēnei momo ka hiahiatia he mōhiotanga matatau o te whakawhitinga rerekētanga. I whakaarotia i tētahi wā he tawhiti atu tēnei i te whānuitanga o te hangarau e wātea ana i ngā wā onamata, engari ko te kitenga o te tikanga Antikythera i te tau 1902 kua whakapumautia e mōhiotia ana ēnei momo pūrere e nga Kariki onamata.  Pātai: Ahea i kitea ai tētahi tikanga onamata?
Ko te tau 1902
