The story of the golden crown does not appear anywhere in Archimedes' known works. The practicality of the method described has been called into question due to the extreme accuracy that would be required to measure water displacement. [35]
Archimedes' insight led to the solution of a problem posed by Hiero of Syracuse, on how to assess the purity of an irregular golden votive crown; he had given his goldsmith the pure gold to be used, and correctly suspected he had been cheated by the goldsmith removing gold and adding the same weight of silver.
Archimedes may have used his principle of buoyancy to determine whether the golden crown was less dense than solid gold.. The "Eureka" legend told of Archimedes (287–212 BC), where the philosopher proved that a crown was not solid gold by comparing measurements of its displacement of water and its weight, is a direct forerunner of modern forensic engineering techniques.

Archimedes reportedly exclaimed "Eureka" after he realized how to detect whether a crown is made of impure gold. While he did not use Archimedes' principle in the widespread tale and used displaced water only for measuring the volume of the crown, there is an alternative approach using the principle: Balance the crown and pure gold on a scale ...
Syracusia was designed by Archimedes and built around 240 BC by Archias of Corinth on the orders of Hieron II of Syracuse. The historian Moschion of Phaselis said that Syracusia could carry a cargo of some 1600 to 1800 tons and a capacity of 1,942 passengers. [5] She reputedly bore more than 200 soldiers, as well as a catapult.
Vitruvius related the famous story about Archimedes and his detection of adulterated gold in a royal crown. When Archimedes realized the volume of the crown could be measured exactly by the displacement created in a bath of water, he ran into the street with the cry of "Eureka!", and the discovery enabled him to compare the density of the crown ...

Archimedes' investigation of paraboloids was possibly an idealization of the shapes of ships' hulls. Some of the paraboloids float with the base under water and the summit above water, similar to the way that icebergs float. Of Archimedes' works that survive, the second book of On Floating Bodies is considered his most mature work. [6]
