<prompt> Bheka isigaba esingezansi bese uphendula umbuzo ngemuva kwalokho ngolimi olufanayo nesigaba: Isigaba: UNewton wakha isibonakude sokuqala esibonisa ukukhanya futhi wasungula inkolelo-mbono eyinkimbinkimbi yombala esekelwe ekuboneni ukuthi i-prism ihlukanisa ukukhanya okumhlophe ngemibala ye-spectrum ebonakalayo. Umsebenzi wakhe ekukhanyeni waqoqwa encwadini yakhe enethonya elikhulu i-Opticks, eyanyatheliswa ngo-1704. Wabuye wakha umthetho wokupholisa, wenza ukubalwa kokuqala kwethiyori yejubane lomsindo, futhi wethula umqondo we-Newtonian fluid. Ngaphezu komsebenzi wakhe we-calculus, njengesazi sezibalo uNewton waba negalelo ekutadisheni uchungechunge lwamandla, wahlanganisa i-binomial theorem kuma-non-integer exponents, wasungula indlela yokusondela kwempande yomsebenzi, futhi wahlukanisa iningi lamajika endiza yecubic. Umbuzo: Ubani owayenomthwalo wokubuka ku-spectrum?  <response>: I-Newton
