paragraph_text: In the early 1800s, John Dalton used the concept of atoms to explain why elements always react in ratios of small whole numbers (the law of multiple proportions). For instance, there are two types of tin oxide: one is 88.1% tin and 11.9% oxygen and the other is 78.7% tin and 21.3% oxygen (tin (II) oxide and tin dioxide respectively). This means that 100g of tin will combine either with 13.5 g or 27g of oxygen. 13.5 and 27 form a ratio of 1: 2, a ratio of small whole numbers. This common pattern in chemistry suggested to Dalton that elements react in whole number multiples of discrete units -- in other words, atoms. In the case of tin oxides, one tin atom will combine with either one or two oxygen atoms.

paragraph_text: A food pyramid or diet pyramid is a triangular diagram representing the optimal number of servings to be eaten each day from each of the basic food groups. The first pyramid was published in Sweden in 1974. The 1992 pyramid introduced by the United States Department of Agriculture (USDA) was called the ``Food Guide Pyramid ''. It was updated in 2005, and then it was replaced by MyPlate in 2011.

paragraph_text: Both Sekhemre-Wepmaat Intef and Nubkheperre Intef were sons of a king called Sobekemsaf, most probably Sekhemre Shedtawy Sobekemsaf (Sobekemsaf II today, not I) based on an inscription from a doorjamb from a 17th Dynasty temple at Gebel Antef. While his own tomb has not been located, it was likely located in the area of Dra' Abu el-Naga' where the pyramid tomb of his brother Nubkheperre Intef was found in 2001. The pyramidion of the pyramid of Sekhemre-Wepmaat Intef's pyramid was found in Dra' Abu el-Naga'. It has a slope of 60 degrees and is inscribed with this king's names. The pyramidion is now in the British Museum (BM EA 478).

paragraph_text: Userkaf's pyramid is part of a larger mortuary complex comprising a mortuary temple, an offering chapel and a cult pyramid as well as separate pyramid and mortuary temple for Userkaf's wife, queen Neferhetepes. Userkaf's mortuary temple and cult pyramid are today completely ruined and difficult to recognize. The pyramid of the queen is no more than a mound of rubble, with its funerary chamber exposed by stone robbers.The complex is markedly different from those built during the 4th Dynasty (c. 2613–2494 BC) in its size, architecture and location, being at Saqqara rather than Gizah. As such, Userkaf's pyramid complex could be a manifestation of the profound changes in the ideology of kingship that took place between the 4th and 5th dynasties, changes that may have started during the reign of Userkaf's likely immediate predecessor, Shepseskaf. Some 1500 years after its construction, the pyramid complex was restored under Ramses II. During the much later Saite period (664–525 BC), it was used as a cemetery.

paragraph_text: The Pyramid of Menkaure is the smallest of the three main Pyramids of Giza, located on the Giza Plateau in the southwestern outskirts of Cairo, Egypt. It is thought to have been built to serve as the tomb of the fourth dynasty Egyptian Pharaoh Menkaure.

paragraph_text: The Louvre Pyramid (Pyramide du Louvre) is a large glass and metal pyramid designed by Chinese - American architect I.M. Pei, surrounded by three smaller pyramids, in the main courtyard (Cour Napoléon) of the Louvre Palace (Palais du Louvre) in Paris. The large pyramid serves as the main entrance to the Louvre Museum. Completed in 1989, it has become a landmark of the city of Paris.

paragraph_text: Greek pyramids, also known as the Pyramids of Argolis, refers to several structures located in the plain of Argolid, Greece. The best known of these is known as the Pyramid of Hellinikon. In the time of the geographer Pausanias it was considered to be a tomb. Twentieth century researchers have suggested other possible uses.

paragraph_text: The Masonic Building, located at 296 to 304 Walnut Street and 456 to 460 Newtonville Avenue in the village of Newtonville, in Newton, Massachusetts in the United States, is a historic building built in 1896 as a Masonic Lodge hall. It is a massive four-story redbrick Renaissance-style building with a turret on the corner and a steep slate pyramid roof. The upper floors are still used for meetings of Masonic lodges and appendant orders, while the lower floors are used for retail and office purposes. The building was approved for listing on the National Register of Historic Places in 1986, but due to owner objection it was not listed. However, it was included as a contributing property to the Newtonville Historic District when that district was expanded in 1990.

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: 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 Pyramids of Giza consist of the Great Pyramid of Giza (also known as the Pyramid of Cheops or Khufu and constructed c. 2560 -- 2540 BC), the somewhat smaller Pyramid of Khafre (or Chephren) a few hundred meters to the south - west, and the relatively modest - sized Pyramid of Menkaure (or Mykerinos) a few hundred meters farther south - west. The Great Sphinx lies on the east side of the complex. Current consensus among Egyptologists is that the head of the Great Sphinx is that of Khafre. Along with these major monuments are a number of smaller satellite edifices, known as ``queens ''pyramids, causeways and valley pyramids.

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: There are three known chambers inside the Great Pyramid. The lowest chamber is cut into the bedrock upon which the pyramid was built and was unfinished. The so - called Queen's Chamber and King's Chamber are higher up within the pyramid structure. The main part of the Giza complex is a setting of buildings that included two mortuary temples in honour of Khufu (one close to the pyramid and one near the Nile), three smaller pyramids for Khufu's wives, an even smaller ``satellite ''pyramid, a raised causeway connecting the two temples, and small mastaba tombs surrounding the pyramid for nobles.

Its height will be surpassed by Salesforce Tower, currently under construction. The building no longer houses the headquarters of the Transamerica Corporation, which moved its U.S. headquarters to Baltimore, Maryland, but it is still associated with the company and is depicted in the company's logo. Designed by architect William Pereira and built by Hathaway Dinwiddie Construction Company, at 853 feet (260 m), on completion in 1972 it was the eighth - tallest building in the world.
