Tuhia he tohutoro mō tēnei wāhanga - Ko te Ahorangi Winthrop tētahi o ngā tangata pūtaiao tino nui i Amerika i te rau tau 18, ā, he tino nui te pānga ki tōna nekehanga wawe ki New Ingarangi. Ko Benjamin Franklin raua ko Benjamin Thompson (Count Rumford) pea he nui o ta raua hiahia mo te rangahau putaiao ki tana awe. He mana nui hoki tana ki te maatauranga rapunga whakaaro o John Adams i te wa o te Harvard. I pānui rārangi ia ki te Royal Society i Rānana, ā, ko ia tētahi o ngā tohunga mātauranga o Amerika tuatahi i whakaarohia i Uropi. I kōwhiria ia ki te American Philosophical Society i te tau 1768. I mōhiotia ia mō tana whakamātau ki te whakamārama i te ru nui o Lisbon i te tau 1755
hei kaupapa pūtaiao, kaua hei kaupapa whakapono, ā, ko tana whakamahinga o ngā tātaitanga pāngarau ki ngā mahi rerenga whenua whai muri i te rerenga whenua nui, ko te pūtake o te kerēme i tukuna i runga i tōna ingoa hei kaiwhakarewa o te pūtaiao o te rerenga whenua. I tua atu, i mātakitaki ia i ngā whakawhitinga o Mercury i te tau 1740 me te tau 1761 ka haere ki Newfoundland ki te mātakitaki i tētahi whakawhitinga o Venus. I haere ia i runga i tētahi kaipuke i whakaratohia e te Porowini o Massachusetts - tērā pea ko te haerenga pūtaiao tuatahi i tukuna e tētahi kāwanatanga o Amerika.
