Einstein Albert a tr\u0103it \u00eentre anii 1879 \u015fi 1955 . Einstein a fost un fizician german dar a fost \u015fi unul dintre cei mai mari fizicieni ai secolului XX . El s-a n\u0103scut la Ulm \u00een Germania.\u00centre anii 1895 \u015fi 1914 a tr\u0103it \u00een Elve\u0163ia , unde a absolvit Politehnica din Zurich \u00een anul 1900 . \u00centre 1902 \u015fi 1909 a lucrat la biroul de patente din Berna . \u00cen 1914 a fost numit Profesor la Universitatea din Berlin . Ales membru al Academiei Pursiene , a fost director al Institutului de Fizic\u0103 din Berlin \u015fi profesor universitar p\u00een\u0103 \u00een anul 1933 , c\u00eend venirea la putere a lui Hitler l-a silit s\u0103 emigreze \u00een S.U.A. unde a tr\u0103it p\u00een\u0103 la sf\u00eer\u015fitul vie\u0163ii . Aici a fost profesor la Universitatea din Princeton . <\/span><\/span><\/div>\n
<\/div>\n
Activitatea de cercetare a lui Einstein a \u00eembr\u0103ti\u015fat mai multe domenii ale fizicii . Ca rezultat al primelor \u00eencerc\u0103ri , a explicat mi\u015fcarea brownian\u0103 pe baza ipotezei cuantice , efectul fotoelectric \u00een 1905 , postul\u00eend structura discontinu\u0103 a luminii . \u00cen acela\u015fi an a publicat \u00een \u201eAnnalen der Physik\u201d din Berlin dou\u0103 articole : \u201eAsupra electrodinamicii corpurilor \u00een mi\u015fcare\u201d \u015fi \u201eDepinde oare iner\u0163ia corpului de cantitatea de energie pe care o con\u0163ine?\u201d , unde \u015fi-a elaborat ideile , care au revolu\u0163ionat \u015ftiin\u0163a , cunoscute ulterior sub numele de teoria relativit\u0103\u0163ii restr\u00eense . Einstein a explicat legile ac\u0163iunii chimice a luminii , c\u0103ldura specific\u0103 a solidelor , efectul giromagnetic in 1915 , numit \u015fi efectul Einstein de Hass . Prin aceste lucr\u0103ri Einstein a devenit unul dintre pionierii teoriei cuantelor . A aplicat calculul probabilit\u0103\u0163ilor la studiul mi\u015fc\u0103rii browniene , ob\u0163in\u00eend o valoare a num\u0103rului lui Avogardo . <\/span><\/span><\/div>\n
<\/div>\n
\u00cen anul 1916 a publicat , tot \u00een \u201eAnnalen der Physik\u201d din Berlin , articolul \u201eBazele teoriei relativit\u0103\u0163ii generalizate\u201d , care cuprinde teoria general\u0103 a relativit\u0103\u0163ii , sau , cum se mai nume\u015fte , teoria gravita\u0163iei . <\/span><\/span><\/div>\n
<\/div>\n
Teoria relativit\u0103\u0163ii generalizate l\u0103rge\u015fte teoria relativit\u0103\u0163ii restr\u00eense , studiind orice fel de mi\u015fcare a corpurilor materiale ; ea proclam\u0103 valabilitatea legilor fizice pentru toate mi\u015fc\u0103rile , chiar \u015fi pentru cele neiner\u0163iale , adic\u0103 neuniforme \u015fi prin urmare , valabilitatea lor \u00een orice sistem de referin\u0163\u0103 . <\/span><\/span><\/div>\n
<\/div>\n
Prin rezultatele ob\u0163inute , activitatea teoretic\u0103 si practic\u0103 a lui Einstein a dat r\u0103spuns celor mai acute probleme ridicate de dezvoltarea vertiginoas\u0103 a fizicii moderne . De aceea Lenin \u00eel consider\u0103 pe Einstein ca pe unul dintre marii transformatori ai \u015ftiin\u0163elo naturii . Concep\u0163ia despre lume a lui Einstein a evoluat de-a lungul vie\u0163ii sale in direc\u0163ia unei afirm\u0103ri tot mai hot\u0103r\u00eete a materialismului . De\u015fi nu a cunoscut materialismul dialectic , Einstein s-a c\u0103l\u0103uzit \u00een mod spontan \u00een crea\u0163ia sa \u015ftiin\u0163ific\u0103 dup\u0103 legile dialecticii materialiste , aplic\u00eendu-le la cunoa\u015fterea naturii . Einstein a comb\u0103tut , mai ales c\u0103tre sf\u00eer\u015fitul vie\u0163ii , pozitivismul machist , a c\u0103rui influen\u0163\u0103 o suferise \u00een prima perioad\u0103 a activit\u0103\u0163ii sale , fiind atras de critica pe care Mach o f\u0103cea mecanismului fizicii clasice .<\/span><\/span><\/div>\n
<\/div>\n
 \u00cen opozi\u0163ie cu subiectivismul pozitivi\u015ftilor , el a sus\u0163inut \u201e\u00eentelegerea \u015fi interpretarea naturii ca realitate obiectiv\u0103\u201d , a respins concep\u0163ia pozitivist\u0103 despre \u015ftiin\u0163\u0103 ca simpl\u0103 sistematizare a datelor senzoriale , lipsit\u0103 de con\u0163inut obiectiv . <\/span><\/span><\/div>\n
<\/div>\n
Teoria relativit\u0103\u0163ii \u015fi \u00eentreaga oper\u0103 \u015ftiin\u0163ific\u0103 a lui Einstein au confirmat , independent de \u00eencerc\u0103rile de interpretare idealist\u0103 a acestora de c\u0103tre filozofii burghezi , tezele materialismului dialectic privitoare la unitatea dialectic\u0103 dintre absolut si relativ , la conexiunea \u015fi la interdependen\u0163a tuturor laturilor realit\u0103\u0163ii , la unitatea organic\u0103 dintre spa\u0163iu , timp , materie \u015fi mi\u015fcare (etc) . Einstein a fost un democrat convins \u015fi un lupt\u0103tor consecvent pentru pace . \u00centre anii 1930 \u015fi 1940 el a luat parte activ\u0103 , al\u0103turi de M.Gorki, R.Ronald \u015fi H.Barbusse , la lupta antir\u0103zboinic\u0103 \u015fi antifascist\u0103 . \u00cen ultimii ani ai vie\u0163ii , el s-a opus folosirii armelor atomice , s-a pronun\u0163at pentru controlul interna\u0163ional al energiei atomice . Einstein s-a ridicat , \u00een 1953 , contra presiunilor exercitate de Comitetul pentru cercetarea activit\u0103\u0163ii \u201eantiamericane\u201d , a chemat intelectualitatea american\u0103 la o atitudine demn\u0103 .         Einstein a fost laureat al premiului Nobel \u00een 1921 \u015fi a mai avut \u015fi alte opere , dup\u0103 cum urmeaz\u0103 : \u201eProblemele cosmologiei \u015fi teoria relativit\u0103\u0163ii generale\u201d \u00een anul 1917 ,\u201eTeoria unitar\u0103 a c\u00eempului\u201d \u00een anul 1929 \u015fi \u201eEvolu\u0163ia fizicii\u201d \u00eempreuna cu L.Infeld \u00een anul 1938 . <\/span><\/span><\/div>\n

Despre efectul Einstein de Has<\/span><\/u><\/span><\/div>\n
<\/div>\n
\n<\/div>\n
<\/div>\n
Este un efect de tip magneto-mecanic care const\u0103 \u00een rotirea unui corp feromagnetic \u00een timpul magnetiz\u0103rii , datorit\u0103 leg\u0103turii dintre momentele magnetice \u015fi mecanice ale electronilor din \u00eenveli\u015furile atomilor . Acest efect giromagnetic a fost descoperit \u00een 1915 .<\/span><\/span><\/div>\n
