paragraph_text: The Pyramid of the Sun is the largest building in Teotihuacan, believed to have been constructed about 200 CE, and one of the largest in Mesoamerica. Found along the Avenue of the Dead, in between the Pyramid of the Moon and the Ciudadela, and in the shadow of the massive mountain Cerro Gordo, the pyramid is part of a large complex in the heart of the city.

paragraph_text: Several public-key cryptography algorithms, such as RSA and the Diffie–Hellman key exchange, are based on large prime numbers (for example, 512-bit primes are frequently used for RSA and 1024-bit primes are typical for Diffie–Hellman.). RSA relies on the assumption that it is much easier (i.e., more efficient) to perform the multiplication of two (large) numbers x and y than to calculate x and y (assumed coprime) if only the product xy is known. The Diffie–Hellman key exchange relies on the fact that there are efficient algorithms for modular exponentiation, while the reverse operation the discrete logarithm is thought to be a hard problem.

paragraph_text: Based on these estimates, building the pyramid in 20 years would involve installing approximately 800 tonnes of stone every day. Additionally, since it consists of an estimated 2.3 million blocks, completing the building in 20 years would involve moving an average of more than 12 of the blocks into place each hour, day and night. The first precision measurements of the pyramid were made by Egyptologist Sir Flinders Petrie in 1880 -- 82 and published as The Pyramids and Temples of Gizeh. Almost all reports are based on his measurements. Many of the casing stones and inner chamber blocks of the Great Pyramid fit together with extremely high precision. Based on measurements taken on the northeastern casing stones, the mean opening of the joints is only 0.5 millimetre wide (1 / 50 of an inch).

paragraph_text: Ground was broken for the Luxor in March 1992 and the resort officially opened at 4 AM on October 13, 1993, to a crowd of 10,000 people. When it opened, the pyramid, which cost $375 million to build, was the tallest building on the strip and contained 2,526 rooms and a 100,000 sq ft (9,300 m) casino. The resort was financed by ``petty cash ''earned from other Circus Circus Enterprises properties and did not include any outside financial investors. The hotel's pyramid is similar in size to the Red Pyramid and Bent Pyramid of Egypt.

The market square has the town hall ("Rathaus") to the west, the main Lutheran church ("Evangelische Stadtkirche") to the east, and the tomb of Margrave Charles III William in a pyramid in the buildings, resulting in Karlsruhe being one of only three large cities in Germany where buildings are laid out in the neoclassical style.

paragraph_text: Userkaf's pyramid is located on the northeast corner of Djoser's step pyramid complex. The pyramid was originally around 49 metres (161 ft) high and 73 metres (240 ft) large with an inclination of 53° identical to that of Khufu's great pyramid for a total volume of 87,906 m3 (114,977 cu yd). The core of the pyramid is built of small, roughly-hewn blocks of local limestone disposed in horizontal layers. This meant a considerable saving of labor as compared to the large and more accurately-hewn stone cores of 4th Dynasty pyramids. However, as the outer casing of Userkaf's pyramid fell victim to stone robbers throughout the millennia, the loosely assembled core material was progressively exposed and fared much worse over time than that of the older pyramids. This explains the current ruined state of the pyramid.The pyramid core was constructed in a step-like structure, a construction technique similar to that of the 4th dynasty although the building material was of a significantly lower quality. The outer casing of the pyramid was made of fine Tura limestone which certainly ensured Userkaf's construction an appearance similar to that of the glorious 4th Dynasty pyramids. There was however no red granite paneling over the lower part of the pyramid as in the case of the Pyramid of Menkaure.

paragraph_text: The question of whether the government should intervene or not in the regulation of the cyberspace is a very polemical one. Indeed, for as long as it has existed and by definition, the cyberspace is a virtual space free of any government intervention. Where everyone agree that an improvement on cybersecurity is more than vital, is the government the best actor to solve this issue? Many government officials and experts think that the government should step in and that there is a crucial need for regulation, mainly due to the failure of the private sector to solve efficiently the cybersecurity problem. R. Clarke said during a panel discussion at the RSA Security Conference in San Francisco, he believes that the "industry only responds when you threaten regulation. If industry doesn't respond (to the threat), you have to follow through." On the other hand, executives from the private sector agree that improvements are necessary, but think that the government intervention would affect their ability to innovate efficiently.

paragraph_text: Bateman was responsible for the building of 36 new buildings for the university both on and off campus, including the expansion of the Harold B. Lee Library. He was also one of several key college leaders who brought about the creation of the Mountain West Conference, which BYU's athletics program joined — BYU previously participated in the Western Athletic Conference. A BYU satellite TV network also opened in 2000 under his leadership. Bateman was also president during the September 11th attacks in 2001. The planes crashed on a Tuesday, hours before the weekly devotional normally held at BYU. Previous plans for the devotional were altered, as Bateman led the student body in a prayer for peace. Bateman was followed by Cecil O. Samuelson in 2003. Samuelson was succeeded by Kevin J Worthen in 2014.
