What did the ancient mathematician Archimedes do to impede the Roman military?
ChuckSiata
Archimedes invented military machines to help defend his city, Syracuse, when it was besieged by the Romans.
He created the Claw of Archimedes. This weapon consisted of a tall arm with a large metal hook hanging from it. When the hook was dropped onto an attacking ship the arm swung upwards, lifting the ship out of the water and sinking it.
He was also said to have created the Archimedes heat ray. It used a series of reflecting surfaces pointed at Roman ships to burn them. It is thought that he may have used many polished bronze or copper shields acting as parabolic reflectors. The credibility of this story had been questioned because 1) it had not proved very effective in some experiments (though one in Greece succeeded at a distance of 50 feet) 2) Syracuse faced east and the system could have only been used in the morning 3) other methods such as lit arrows and catapults throwing incendiary materials would have been much simpler and cheaper.

The War of 1812, between the United States of America and the British Empire (particularly Great Britain and British North America), was fought from 1812 to 1815. There were several immediate stated causes for the U.S. declaration of war. First, a series of trade restrictions introduced by Britain to impede American trade with France, a country with which Britain was at war; the U.S. contested these restrictions as illegal under international law.[3] Second, the impressment (forced recruitment) of U.S. citizens into the Royal Navy.
