In particular, this was achieved by the conceptualization of invisible or “subtle” materials, thought to be closely linked to atmospheric stratification.\u003cbr\u003e\u003cbr\u003eSubtle matter was introduced, largely to reconcile contradictory results concerning the estimation of the height of the atmosphere. These estimations were based on different methods, mainly using the observation of meteors and the refracted and reflected light of stars.\u003cbr\u003e\u003cbr\u003eTaking as its common thread the question of the height of the atmosphere, which was omnipresent in the texts at the time, this book traces the history of the discovery of the atmosphere and the many questions it generated.","brand":"ISTE Ltd and John Wiley \u0026 Sons Inc","offers":[{"title":"Default Product","offer_id":54218271359320,"sku":"9781786307170","price":171.06,"currency_code":"EUR","in_stock":true}],"url":"https:\/\/agendabookshop.com\/products\/physics-of-the-terrestrial-environment-subtle-matter-and-height-of-the-atmosphere","provider":"Agenda Bookshop","version":"1.0","type":"link"}
