Casti, <span style="font-style: italic;">Paradigme Pierduta</span>, la Editura Pergament... si nu va mai trebuie altceva! Pe carte scrie asa: "...unul dintre cei mai mari autori de literatura de popularizare, iar volumul (...) constituie baza cursului de stiinta in mai multe colegii americane. (...)".<br /><br />Cartea se numeste "Paradigme pierdute" pentru ca e vorba despre sensul 2 al <span class="def" onclick="return searchClickedWord(event);"><b>PARADÍGMĂ</b>, <i>paradigme</i>, s.f. <b>1.</b> (...) <b>2.</b> (Înv.) Exemplu, model; pildă; învăţătură. – Din lat. <b>paradigma</b>, ngr. <b>parádigma</b>. (din DEXonline), "pierdute" pentru ca e, de fapt, vorba de cateva cazuri in care Stiinta a renuntata la "tiparele/medelele" discutate -- chestie din care, de fapt, Stiinta a invatat, ca din greseli..., sau de alte cazuri in care "tiparele/modelele" aflate in competitie nu au livrat (inca) un "castigator". </span><br /><br />Eu am citit capitolele 1, 2, 4 si acum (27/10/2007) il citesc pe 7.

Richard Feynman!<br /><br />QED este o abreviere pentru Quantum ElectroDynamics, termenul englezesc pentru "Electrodinamica Cuantica". Electrodinamica este teoria campului electromagnetic... si "cuantica" inseamna ca e despre cele care au loc la "nivel cuantic", adica atomic, sub-atomic, etc... acolo unde actioneaza legile Mecanicii Cuantice si, deci, Principiul de Nedeterminare al lui Heisenberg. (Ceea ce inseamna, in esenta, sub nivelul microscopic... in lumea atomilor si moleculelor.)<br /><br />Eu, unul, am avut placerea de a afla ce este o "diagrama Feynman", de la chiar inventatorul lor. (Diagramele astea sunt un fel de a rezolva rapid o problema, fara a scrie formule... facand, numai, niste desene... asta fiind si motivul pentru care se numesc "diagrame"... din pacate, la facultate nu se invata asa ceva!), dar lucrurile prezentate sunt impresionante (pe bune!), pentru ca nici prin cap nu va trece cum sta treaba in lumea atomilor si fotnilor!<br /><br /><br />Cartea e aparuta la editura Pergament si costa 20 RON.<br /><br />B.<div class="blogger-post-footer"><img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/2020097768059415569-1490993304645359520?l=fizicasimpatica.blogspot.com' alt='' /></div>Lorin-Bogdan Popescuhttp://www.blogger.com/profile/17775826926564338416noreply@blogger.com2tag:blogger.com,1999:blog-2020097768059415569.post-77771442345669726372007-10-22T10:48:00.000-07:002007-10-25T04:08:25.394-07:00Hei, a aparut (celebra) <span style="font-style: italic;">Despre caracterul legilor Fizicii</span>, a (celebrului) Richard Feynman... si traducerea e buna!
