Pe data de 1 iulie 1646 se n\u0103\u0219tea\u00a0Gottfried Wilhelm Freiherr von Leibniz<\/strong><\/em>, filozof \u0219i matematician german, unul din cei mai importan\u021bi filozofi de la sf\u00e2r\u0219itul secolului al XVII-lea \u0219i \u00eenceputul celui de al XVIII-lea, unul din \u00eentemeietorii iluminismului german. \u00cen matematic\u0103, Leibniz a introdus termenul de \u201efunc\u021bie<\/em>„, pe care l-a folosit pentru a descrie o cantitate dependent\u0103 de o curb\u0103. Al\u0103turi de Newton, Leibniz este considerat fondatorul analizei matematice moderne.\u00a0Leibniz elaboreaz\u0103 \u00een jurul anului 1675 bazele calculului diferen\u021bial \u0219i integral, de o mare \u00eensemn\u0103tate pentru dezvoltarea ulterioar\u0103 a matematicii \u0219i fizicii, independent de Isaac Newton<\/em>, care enun\u021base deja principiile calculului infinitezimal \u00eentr-o lucrare din 1666. Simbolurile matematice introduse de Leibniz \u00een calculul diferen\u021bial \u0219i integral se folosesc \u0219i ast\u0103zi. Perfec\u021bion\u00e2nd realiz\u0103rile lui Blaise Pascal<\/em>, Leibniz construie\u0219te un calculator mecanic, capabil s\u0103 efectueze \u00eenmul\u021biri, \u00eemp\u0103r\u021biri \u0219i extragerea r\u0103d\u0103cinii p\u0103trate. Dezvolt\u0103 forma modern\u0103 de num\u0103rare binar\u0103, utilizat\u0103 ast\u0103zi \u00een informatic\u0103 \u0219i pentru calculatoare. Leibniz a \u00eencercat s\u0103 creeze un calcul logic, o logic\u0103 bazat\u0103 pe utilizarea simbolurilor, fiind un precursor al logicii matematice.\u00a0\u00cen fizic\u0103, Leibniz a introdus no\u021biunea de \u201efor\u021b\u0103 vie<\/em>” (mv2) ca m\u0103sur\u0103 a mi\u0219c\u0103rii (energia cinetic\u0103<\/em>, cum o numim azi), diferit\u0103 de cea de „cantitate de mi\u0219care” (mv) (impuls<\/em>, cum \u00eel numim azi), premerg\u0103toare no\u021biunii moderne de energie.<\/p>\n

Zi bun\u0103 pentru matematic\u0103. Pe 1 iulie 1788 se n\u0103\u0219tea un alt matematician imoprtant –\u00a0Jean-Victor Poncelet,\u00a0<\/strong><\/em>matematician, inginer francez \u0219i director al celebrului institut de \u00eenv\u0103\u021b\u0103m\u00e2nt superior, \u00c9cole Polytechnique<\/em>. Prin contribu\u021biile sale, a revigorat domeniul geometriei proiective, al c\u0103rui pionier a fost G\u00e9rard Desargues.\u00a0Printre contribu\u021biile sale notabile, putem men\u021biona: aplica\u021biile \u00een geometria proiectiv\u0103 ale no\u021biunii de pol \u0219i polar\u0103, ale rela\u021biei de conjugare armonic\u0103, studii asupra teoremei lui Feuerbach<\/em>, asupra numerelor complexe sau despre principiul dualit\u0103\u021bii \u00een geometria proiectiv\u0103.<\/p>\n
