Showing results for "eureka" in History

Many of us know little about Archimedes other than his "Eureka" exclamation upon discovering that he could immerse an object in a full tub of water and measure the spillage to determine the object's weight. That seemingly simple observation not only proved to King Hieron II of Syracuse that a certain amount of silver had been used in what was supposed to be his solid-gold crown, it established the key principles of buoyancy that govern the flotation of hot-air balloons, ships, and denizens of the sea.

Il fuoco, i vestiti, le armi; il cibo, l’alcol, la scrittura; la medicina, la ruota, le nuove terre. Quella dell’umanità è una storia avventurosa, costellata di snodi fondamentali, piccole e grandi scoperte o invenzioni che hanno cambiato per sempre la nostra civiltà e l’ambiente intorno a noi e ci hanno trasformato da ominidi pelosi ma ingegnosi in esseri umani dotati di humour e gusti raffinati (e chissà se è stato un bene).

The long history of science is illuminated by eureka moments - occasional and startling breakthroughs that change the way we think about ourselves and our universe. Adam Hart-Davis guides us through the history of science by examining 16 of the most formative years for our understanding of astronomy, medicine, biology, space and time. Episodes include 1965, in which Adam examines how mankind's peculiar gift for self-destruction fuelled the race to the moon. He leafs through a book published in 1628, which described, for the first time, how blood circulates around the human body.
