\u00cen data de 11 octombrie 1884<\/strong> se n\u0103\u0219tea\u00a0Friedrich Karl Rudolf Bergius,\u00a0cercet\u0103tor chimist german care a inventat un proces de transformare a c\u0103rbunilor \u00een petrol \u0219i a lemnului \u00een zah\u0103r.\u00a0A fost profesor la Universitatea din Hanovra, a avut numeroase contribu\u021bii la inventarea \u0219i perfec\u021bionarea metodelor chimice de sintez\u0103 la presiuni \u00eenalte. A ob\u021binut benzin\u0103 sintetic\u0103 prin hidrogenarea c\u0103rbunilor la presiune \u00eenalt\u0103 \u0219i zah\u0103r alimentar prin zaharificarea celulozei \u00een mediu acid. \u00cen 1931 a primit Premiul Nobel pentru chimie \u00eempreun\u0103 cu Carl Bosch.<\/p>\n

\u00cen data de 11 octombrie 1889<\/strong> se stingea din via\u021b\u0103\u00a0James Prescott Joule, fizician englez autodidact \u0219i un fabricant de bere. A devenit celebru datorit\u0103 unei experien\u021be celebre, destinat\u0103 a determina echivalentul mecanic al caloriei, efectuat\u0103 \u00een anul 1842. Prin aceast\u0103 experien\u021b\u0103, Joule a verificat principiul conserv\u0103rii \u0219i transform\u0103rii energiei.\u00a0A enun\u021bat \u00een 1841 legea transform\u0103rii energiei \u00een conductoare, conform c\u0103reia energia disipat\u0103 sub form\u0103 de c\u0103ldur\u0103 la trecerea curentului electric printr-un conductor este propor\u021bional\u0103 cu rezisten\u021ba conductorului, cu p\u0103tratul intensit\u0103\u021bii curentului \u0219i cu timpul, E =RI2t<\/em>. Aceast\u0103 echivalare este cunoscut\u0103 ca legea lui Joule<\/em>.\u00a0Este descoperitorul efectului magnetostrictiv, pe care l-a explicat \u00een anul 1847.\u00a0A adus o contribu\u021bie important\u0103 \u0219i \u00een fizica molecular\u0103, stabilind c\u0103 energia intern\u0103 a unui gaz depinde de temperatur\u0103 \u0219i a calculat viteza moleculelor unui gaz, pentru prima dat\u0103 \u00een fizic\u0103.\u00a0\u00cempreun\u0103 cu William Thomson, \u00een 1852, a observat c\u0103 mic\u0219orarea temperaturii unui gaz ce se destinde f\u0103r\u0103 a efectua un lucru mecanic, numit efect Joule – Thomson.\u00a0Datorit\u0103 importantului s\u0103u rol din fizic\u0103, unitatea de m\u0103sur\u0103 a energiei a fost numit\u0103 \u00een onoarea sa joule<\/strong><\/em>.<\/p>\n
