Phraseologism: Eureka! Meaning: The cry "Eureka!" serves to express joy from a solution to a problem found, from an unexpected and successful thought. Origin: From ancient Greek: "I found!" The expression of the great mathematician and mechanic of Ancient Greece, Archimedes (287-212 BC), who was killed by Roman soldiers during the storming of the city of Syracuse. The history of this expression was told by the famous Roman engineer and architectural theorist Vitruvius (1st century BC) in the 9th book of his treatise On Architecture. The Syracusan king Hieron ordered a crown of pure gold from his jeweler. He did his job perfectly, and the king of Syracuse was pleased. But he was soon informed that the master stole some of the gold and cast the product not from pure gold, but from an alloy of gold and silver. Since the crown weighed as much as the piece of gold given to the master, it was difficult to prove the master's guilt, and Hieron did not want to melt the crown. Then the king turned to the great Archimedes for help: how to catch a thief? Archimedes, although not immediately, but found the answer to this question. One day, while in the bathhouse, he sat down in a bathtub filled to the very brim, and the water, of course, poured onto the floor. And then it dawned on the thinker. "Eureka!" he cried, and, forgetting about everything in the world, how he was, naked, he ran home to set up an experiment there in accordance with his guess. He repeated this experience already in the palace of Hieron, especially for the king. Archimedes lowered into a bowl filled to the brim a piece of gold of the same weight as the ingot given to the master. Noticing how much water had spilled out, he lowered the crown itself into the same cup, again filled to the brim. Much more water poured out, therefore, the finished product is larger in size than the original material. And this could only happen if part of the gold was actually replaced by silver: it is lighter in weight than gold, which means that its volume was greater than the volume of stolen gold. Only in this way could the master achieve that the weight of the finished product was equal to the weight of the source material. So, having revealed this deception, Archimedes discovered one of the main laws of physics, named after him. The essence of the law: a buoyant force equal to the weight of the water displaced by this body acts on a body immersed in water. Another version of the same law is also possible: a body immersed in a liquid loses as much in its weight as the liquid displaced by it weighs. This first law of hydrostatics, discovered by Archimedes, gave an answer to a question that had long worried ancient philosophers: why do some bodies sink, for example, a stone weighing 1 kg, while others that are much heavier than a stone, for example, a fifty-kilogram log, on the contrary, remain on the surface of the water . It turns out that the more water the body displaces, the lighter it becomes. This means that if a body weighs more than the water displaced by it, it sinks; if less, it remains afloat.
