what was one of the weapon technologies that emerged during the crusades
counterweight trebuchets

Counterweight trebuchet (12th century) Powered solely by the force of gravity, these catapults revolutionized medieval siege warfare and construction of fortifications by hurling huge stones unprecedented distances. Originating somewhere in the eastern Mediterranean basin, counterweight trebuchets were introduced in the Byzantine Empire around 1100 CE, and was later adopted by the Crusader states and as well by the other armies of Europe and Asia. Greek fire (7th century) An incendiary weapon which could even burn on water is also attributed to the title: American military technology during World War II text: American military technology during World War II American military technologies developed during World War II became more advanced and specialized as the war progressed. The technologies produced ranged in complexity from relatively simple items such as small arms and armored vehicles, including tanks, to more complex items such as the atomic bomb. The latter, produced under the secretive Manhattan Project, proved to be an incredibly powerful weapon that revolutionized warfare and was used to end the war. Other technologies, such as the M4 Sherman tank, the M1 Garand and M1 Carbine, and the gas mask, were refinements on previously existing title: Technology during World War II text: Ultra code breaking allowed convoys to be steered around German U-Boat wolfpacks. The actual weapons; the guns, mortars, artillery, bombs, and other devices, were as diverse as the participants and objectives. A large array were developed during the war to meet specific needs that arose, but many traced their early development to prior to World War II. Torpedoes began to use magnetic detonators; compass-directed, programmed and even acoustic guidance systems; and improved propulsion. Fire-control systems continued to develop for ships' guns and came into use for torpedoes and anti-aircraft fire. Human torpedoes and the Hedgehog were also developed. New production title: History of technology text: gene therapy (introduced 1990), 3D printing (introduced 1981), nanotechnology (introduced 1985), bioengineering/biotechnology, nuclear technology, advanced materials (e.g., graphene), the scramjet and drones (along with railguns and high-energy laser beams for military uses), superconductivity, the memristor, and green technologies such as alternative fuels (e.g., fuel cells, self-driving electric and plug-in hybrid cars), augmented reality devices and wearable electronics, artificial intelligence, and more efficient and powerful LEDs, solar cells, integrated circuits, wireless power devices, engines, and batteries. Perhaps the greatest research tool built in the 21st century is the Large Hadron Collider, the largest single machine ever built. The understanding of particle title: Scorpio (weapon) text: the Middle Ages in Western Europe, but re-appeared during the First Crusade in the form of a new type of catapult based on a system of slings and counterweights for the projection of stone balls, and as giant crossbows as the field of metallurgy progressed, allowing more reliable metal tension weapons. In 52 BC, during the siege of Avaricum in the war against the Gauls, Julius Caesar mentions the "scorpio" in use as an anti-personnel weapon against the Gallic town's defenders. The late third or early fifth century Roman author Vegetius described weapons like the scorpion mounted on carts for
