WitrynaTHUS did Isaac Newton (1642-1727, F.R.S. 1672, P.R.S. 1703-1727) introduce his celebrated letter to Oldenburg on the prismatic spectrum and the compound nature of white light (1). Its production was stimulated by the favourable reception given by the Royal Society to his reflecting telescope (2), which led to his election as a Fellow on … WitrynaXMM-Newton (od ang.
