When was the taj mahal added to the world heritage list?
The Taj Mahal was listed in UNESCO World heritage sites in 1983. The Taj Mahal is a great mausoleum of white marble. It was built in Agra between 1631 and 1648 by the Mughal emperor Shah Jahan in memory of his beloved wife in Agra. It took around 17 years to complete. It is a precious jewel of Muslim archaology in India.
What are the benefits of taking GCSE history?
GCSE History is a good choice if you want a basis to do anything to do with Law, Politics, Archaology etc. It is also a good subject to do to balance out more artistic subjects. Historical analysis is a well looked on skill. It will also give you some general knowledge about History in general. You may have the option of going on some good school trips such as to the Belgium/france to see the battlefields.
How did thieves break into the pyramid?
Thieves would find a small hole or opening and make it bigger with a stone or chizel. Then, when the hole was big enough, they would throw rocks in to make sure there weren't any booby traps nearby. They would then feel their way around with a lighted torch.
What did the ancient romans invent or modify?
Mostly the Romans made good use and imrpoved on things.There is a debate on wether they invented the hypocaust (Aa system of underfloor heating) or not. A Roman writerattributed the invetion of the hypocaust to Sergius horata, a Roman frm Naples. Archaology has shown that it was knwn by the Greeks. Moreover, the word is Greek. It is not known whether the Romans knew the Greek ones. In any case, they developed a much better type of hypocaust. The floor was raised above the ground by pillars which left a space inside that was filled with hot air from a furnace. The heat from the underfloor heated the air in the room. Passages boxed by ceramic tiles were put inside the walls to move the air to flues on the roof and to heat the walls.The Romans adopted the cranes of the Greks and invented new and more powerful ones.The Romans adopted the cranes of the Greeks and massively improved on them. The simplest one was the trispastos, which had triangular frame held up by two ropes fixed to the ground, a winch, a rope, and a block with three pulleys. It had had a mechanical advantage of 3:1, and single man could raise 150 kg. The pentaspastos had five pulleys. The polyspastos had a set of three by five pulleys with two, three or four masts depending on the maximum load they could lift. It was worked by four men at both sides of the winch and could lift 3,000 kg. The Romans also invented the treadwheel, which could replace the winch. This doubled the load to 6,000 kg with only half the crew, because the treadwheel had a much larger diameter and thus a much bigger mechanical advantage. A man walked inside the wheel.The Romans improved on the ballista which was a Greek crossbow-like catapult which launched a large projectile at a distant target with precision using torsion springs. The springs consisted of several loops of twisted ropes. The Romans developed a number of versions. The Carroballista was a cart-mounted version. The Manuballista was a handheld version and was similar to a crossbow. The ancient sources said that the Romans developed the polybolos, a 'repeating' ballista which shot 11 shots a minute. This was at least four times the rate of an ordinary ballista. However, none has been found by archaeologists.The Romans invented the onager, A very powerful sling catapult for launching heavy rock projectiles. The catapults of the Middle Ages were modelled on the onager.The greatest achievement of the Romans was what historians call the Roman architectural revolution or concrete revolution. This involved the extensive use of concrete, the barrel (simple) arch and the vaulted arch. These three elements enabled the Romans to go beyond Greek methods of construction which used cut-stone and post-and-beam or post-and-lintel structures. They became essential for large roofs and large buildings, such as basilicas (public buildings) amphitheatres (arenas), theatres, baths, circuses (racing tracks) domes, forts and fortifications and dams. They also made it possible to build bridges which were much longer than before and could cross much wider rivers and valleys.Prior to the Romans concrete was used very little. It is not known whether the Romans invented it independently. In any case, they were the first to made large scale use of it. Their concrete was as resistant as modern concrete. It also set underwater (and therefore could be used to build docks for ports, dams and bridges). It was less fluid than modern concrete and had to be layered by hand. It was made by mixing a volcanic rock called pozzolana (which is named after Pozzuoli, a suburb of Naples) with lime and adding rubble from stones, bricks or pottery shreds as aggregates which added body to it. Concrete had technical and practical advantages. It was exceptionally strong and could span great distances when shaped into arches, vaults and domes as it could be moulded. It was layered into a formwork and it took the shape of its container. It did not require skilled labour and therefore was cheaper. It was much faster for construction than laborious masonry walls. It was safer because concrete vaulted roofing was fireproof, unlike the wooden-beamed roofs of traditional post-and-lintel construction methods.The potential of the previously very little used arch and vault, was fully exploited for the first time. The Romans were the first to fully appreciate the advantage of these structures and make large scale use of them. The Etruscans are thought to have invented the simple (barrel) arch. The oldest example of the vaulted arch has been found in the Greek city of Pergamon (in western Turkey). The simple, arch has a strong load- bearing capacity and was useful to build large walls without using the post-and-lintel method and to build bridges which were much longer than ever before. The vault (vaulted arch) has an even greater load-bearing capacity and its structure is suited to support large roofs. Their construction in concrete made them easier to build and even stronger. The Romans built lager, monumental arches and vaults on a grand scale. However, they did not abandon masonry arches and vaults. The vaulted arch came into two forms: the groin arch is formed by two to four intersecting barrel (simple) arches and the rib arch, where the intersecting arches were of different diameter.
