In 275 bc who was called to investigate the possible forgery of the king of syracuse’s gold crown

The correct answer is "Archimedes."

In 275 BC the man who was called to investigate the possible forgery of the king of Syracuse’s gold crown was Archimedes.

Archimedes knew that gold was denser than silver. That being the case, a piece of gold should be smaller than a piece of silver of the same weigh. So Archimedes compared the volume of the crown to the volume of the amount of gold that Hiero had given the goldsmith. That is when Archimedes used the bucket with water to introduce the crown and see how much water was displaced.

the first historical instance of china engaging in internationalism was during the han dynasty.[1] at the start of the han dynasty, the huns in the north were attacking the frontiers of han and trying to obtain riches. emperor wu of han wanted to gain an alliance with a country called dayuezhi so the two countries could join together and fight against the huns.[2] to obtain this alliance, emperor wu sent zhang qian to the west to establish economic and cultural connections.[2] history records that during the han dynasty there were four primary avenues of contact between china and europe. they included the northern land route, the central land route, the southern sea route, and the far southern sea route.[1] the most famous of these routes is the central land route, or the classical silk road, comprising a network of roads stretching from northwest china to the ports of syria and the black sea, which passed through the oasis of the turkestans and northern persia.[1] the silk road was significant for chinese emperors because it provided dominance over central asia by developing resources and provided new markets for the export of china's most valuable resources.[1]
