Geocache Description:

Archimedes. Do you know "Archimedes' principle"?

Archimedes may have used his principle of buoyancy to determine whether the golden crown was less dense than solid gold.
The most widely known anecdote about Archimedes tells of how he invented a method for determining the volume of an object with an irregular shape. According to Vitruvius, a votive crown for a temple had been made for King Hiero II, who had supplied the pure gold to be used, and Archimedes was asked to determine whether some silver had been substituted by the dishonest goldsmith. Archimedes had to solve the problem without damaging the crown, so he could not melt it down into a regularly shaped body in order to calculate its density. While taking a bath, he noticed that the level of the water in the tub rose as he got in, and realized that this effect could be used to determine the volume of the crown. For practical purposes water is incompressible, so the submerged crown would displace an amount of water equal to its own volume. By dividing the mass of the crown by the volume of water displaced, the density of the crown could be obtained. This density would be lower than that of gold if cheaper and less dense metals had been added. Archimedes then took to the streets naked, so excited by his discovery that he had forgotten to dress, crying ""Eureka!"" (Greek: ""εὕρηκα!,"" meaning ""I have found it!""). The test was conducted successfully, proving that silver had indeed been mixed in.

A pen is not in the cache. Please take a plastic bottle.

古代ギリシア。ヒエロン王が王冠を作らせた時に、「金細工職人が金の一部を横領して銀を混ぜてるらしいぞぉ」という噂が広まりました。そこで、ヒエロンはアルキメデスに「ちょっと調べてくんない？あ、王冠はばらしたり溶かしたりしちゃやーよ」と命じました。
アルキメデスはどぉすべぇ？と思いながら浴場に行きました。ざぶんと浴槽に入り、自分が湯の中に浸かった分だけ湯があふれだすのを見た瞬間、彼はひらめきました！彼は浴場からとびだし「エウレーカ、エウレーカ（わかったぞ、わかったぞ）」と叫びながら真裸のまま自分の家に帰ったそうです。変態ですね。（もっとも、この時代のギリシアでは、男性は裸で運動するのが普通で、裸で外を走っていても別に珍しくはなかったそうですが）。

キャッシュにはペンが入っていません。ペットボトルをお持ちください。
