La data de 4 octombrie 1957<\/strong>, la 19h 29 min 34 s UTC de la Cosmodromul Baikonur, aflat \u00een Kazahstanul Uniunii Sovietice, se lansa primul satelit\u00a0artificial care a orbitat \u00een jurul P\u0103m\u00e2ntului – Sputnik 1.\u00a0Satelitul a fost plasat pe o orbit\u0103 eliptic\u0103 joas\u0103.\u00a0Lansarea lui Sputnik 1 a marcat \u00eenceputul cuceririi spa\u021biale.\u00a0Plasat pe o orbit\u0103 ale c\u0103rei altitudini ini\u021biale ale perigeului \u0219i apogeului erau de 225 \u0219i respectiv 947 km, Sputnik 1 efectua o revolu\u021bie \u00een 96 de minute. Dar slaba altitudine a perigeului s\u0103u l-a f\u0103cut s\u0103 piard\u0103 din altitudine p\u00e2n\u0103 la un apogeu de 600 km, la 9 decembrie 1957. Dup\u0103 ce a f\u0103cut 1.400 de orbite \u00een jurul P\u0103m\u00e2ntului \u0219i a parcurs circa 70 de milioane de kilometri, Sputnik 1 a intrat \u00een atmosfera terestr\u0103 unde s-a consumat la 4 ianuarie 1958.<\/p>\n

\u00cen data de 4 octombrie 1947<\/strong> se stingea din via\u021b\u0103\u00a0Max Karl Ernst Ludwig Planck, fizician german, laureat al Premiul Nobel pentru Fizic\u0103 \u00een 1918.\u00a0A studiat la M\u00fcnchen \u0219i Berlin, av\u00e2ndu-i ca profesori pe Helmholtz, Clausius \u0219i Kirchhoff iar ulterior a devenit el \u00eensu\u0219i profesor de fizic\u0103 (1889-1926). Activitatea sa \u00een domeniul principiilor termodinamicii \u0219i a distribu\u021biei energetice a radia\u021biei unui corp perfect absorbant, pe care a descris-o exact printr-o formul\u0103 celebr\u0103, l-a condus la abandonarea unor principii clasice newtoniene \u0219i la introducerea teoriei cuantice (1900). Pentru aceasta a primit Premiul Nobel pentru Fizic\u0103 \u00een 1918.<\/p>\n","protected":false},"excerpt":{"rendered":"
