Egyptian Geometry
Egyptian geometry refers to geometry as it was developed and used in Ancient Egypt. Their geometry was a necessary outgrowth of surveying to preserve the layout and ownership of farmland, which was flooded annually by the Nile river. We only have a limited number of problems from ancient Egypt that concern geometry. Geometric problems appear in both the Moscow Mathematical Papyrus (MMP) and in the Rhind Mathematical Papyrus (RMP). The examples demonstrate that the ancient Egyptians knew how to compute areas of several geometric shapes and the volumes of cylinders and pyramids. Area The ancient Egyptians wrote out their problems in multiple parts. They gave the title and the data for the given problem, in some of the texts they would show how to solve the problem, and as the last step they verified that the problem was correct. The scribes did not use any variables and the problems were written in prose form. The solutions were written out in steps, outlining the process. Egypt ...

Rhind Mathematical Papyrus
The Rhind Mathematical Papyrus (RMP; also designated as papyrus British Museum 10057 and pBM 10058) is one of the best known examples of ancient Egyptian mathematics. It is named after Alexander Henry Rhind, a Scotland, Scottish antiquarian, who purchased the papyrus in 1858 in Luxor, Egypt; it was apparently found during illegal excavations in or near the Ramesseum. It dates to around 1550 BC. The British Museum, where the majority of the papyrus is now kept, acquired it in 1865 along with the Egyptian Mathematical Leather Roll, also owned by Henry Rhind. There are a few small fragments held by the Brooklyn Museum in New York City and an central section is missing. It is one of the two well-known Mathematical Papyri along with the Moscow Mathematical Papyrus. The Rhind Papyrus is larger than the Moscow Mathematical Papyrus, while the latter is older. The Rhind Mathematical Papyrus dates to the Second Intermediate Period of History of ancient Egypt, Egypt. It was copied by the sc ...

Cubit
The cubit is an ancient unit of length based on the distance from the elbow to the tip of the middle finger. It was primarily associated with the Sumerians, Egyptians, and Israelites. The term ''cubit'' is found in the Bible regarding Noah's Ark, Ark of the Covenant, Tabernacle, Solomon's Temple. The ''common cubit'' was divided into 6 palms × 4 fingers = 24 digits. ''Royal cubits'' added a palm for 7 palms × 4 fingers = 28 digits. These lengths typically ranged from , with an ancient Roman cubit being as long as . Cubits of various lengths were employed in many parts of the world in antiquity, during the Middle Ages and as recently as early modern times. The term is still used in hedgelaying, the length of the forearm being frequently used to determine the interval between stakes placed within the hedge. Etymology The English word "cubit" comes from the Latin noun "elbow", from the verb "to lie down", from which also comes the adjective " recumbent". Ancie ...

Seked
Seked (or seqed) is an ancient Egyptian term describing the inclination of the triangular faces of a right pyramid. The system was based on the Egyptians' length measure known as the royal cubit. It was subdivided into seven ''palms'', each of which was sub-divided into four ''digits''. The inclination of measured slopes was therefore expressed as the number of horizontal palms and digits relative to each royal cubit rise. The seked is proportional to the reciprocal of our modern measure of slope or gradient, and to the cotangent of the angle of elevation.Gillings: Mathematics in the Time of the Pharaohs 1982: pp 212 Specifically, if ''s'' is the seked, ''m'' the slope (rise over run), and \phi the angle of elevation from horizontal, then: :s = \frac = 7\cot(\phi). The most famous example of a seked slope is of the Great Pyramid of Giza in Egypt built around 2550 BC. Based on modern surveys, the faces of this monument had a seked of 5½, or 5 palms and 2 digits, in modern terms e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Annette Imhausen
Annette Imhausen (also known as Annette Warner, born June 12, 1970) is a German historian of mathematics known for her work on Ancient Egyptian mathematics. She is a professor in the Normative Orders Cluster of Excellence at Goethe University Frankfurt. Education and career Imhausen studied mathematics, chemistry, and Egyptology at Johannes Gutenberg University Mainz, passing the Staatsexamen in 1996. She continued to study Egyptology and Assyriology at the Freie Universität Berlin. She completed her doctorate in the history of mathematics at Mainz in 2002 under the joint supervision of David E. Rowe and James Ritter. She held a fellowship at the Dibner Institute for the History of Science and Technology (Cambridge, MA) before she was received a Junior Research Fellowship at the University of Cambridge from 2003 to 2006. She returned to Mainz as an assistant professor from 2006 to 2008, and became a professor at Frankfurt in 2009. Contributions Imhausen is featured in the BBC ...

Lahun Mathematical Papyri
The Lahun Mathematical Papyri (also known as the Kahun Mathematical Papyri) is an ancient Egyptian mathematical text. It forms part of the Kahun Papyri, which was discovered at El-Lahun (also known as Lahun, Kahun or Il-Lahun) by Flinders Petrie during excavations of a workers' town near the pyramid of the 12th dynasty pharaoh Sesostris II. The Kahun Papyri are a collection of texts including administrative texts, medical texts, veterinarian texts and six fragments devoted to mathematics. Fragments The mathematical texts most commented on are usually named: * Lahun IV.2 (or Kahun IV.2) (UC 32159): This fragment contains a table of Egyptian fraction representations of numbers of the form 2/''n''. A more complete version of this table of fractions is given in the Rhind Mathematical Papyrus.Clagett, Marshall ''Ancient Egyptian Science, A Source Book''.

Corinna Rossi
Corinna Rossi (born 1968) is an Italian Egyptologist known for her works on Ancient Egyptian mathematics and Ancient Egyptian architecture, on the archaeology of the Kharga Oasis, and on related topics in the history of Egypt and the Levant. Biography Rossi was born in 1968 in Naples. She studied architecture at the University of Naples Federico II beginning in 1989, earning a laurea in 1994, and then moved to the University of Cambridge for graduate study in the Faculty of Oriental Studies, where she earned an M.Phil. in 1998 and a Ph.D. in 2000 in Egyptology under the supervision of Barry J.

Senenmut
Senenmut ( egy, sn-n-mwt, sometimes spelled Senmut, Senemut, or Senmout) was an 18th Dynasty ancient Egyptian architect and government official. His name translates literally as "mother's brother." Family Senenmut was of low commoner birth, born to literate provincial parents, Ramose and Hatnofer (or "Hatnefret") from Iuny (modern Armant). Senenmut is known to have had three brothers (Amenemhet, Minhotep, and Pairy) and two sisters (Ahhotep and Nofrethor). However, only Minhotep is named outside chapel TT71 and tomb TT353, in an inventory on the lid of a chest found in the burial chamber of Ramose and Hatnofer. More information is known about Senenmut than many other non-royal Egyptians because the joint tomb of his parents (the construction of which Senenmut supervised himself) was discovered intact by the Metropolitan Museum in the mid-1930s and preserved. Christine Meyer has offered compelling evidence to show that Senenmut was a bachelor for his entire life: for instance ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Menna
The ancient Egyptian official named Menna carried a number of titles associated with the agricultural estates of the temple of Karnak and the king. Information about Menna comes primarily from his richly decorated tomb (TT69, TT 69) in the necropolis of Sheikh Abd el-Qurna, Sheikh Abd al-Qurna at Thebes, Egypt, Thebes. Though his tomb has traditionally been dated to the reign of Thutmose IV, stylistic analysis of the decoration places the majority of construction and decoration of the tomb to the reign of Amenhotep III. Titles Menna was unique for the Eighteenth Dynasty of Egypt, 18th Dynasty because he carried titles associated with both temple and palace administration. Though the pharaoh technically owned both temple and palace agricultural estates, administration of these institutions was traditionally separated. Egyptologist Dr. Melinda Hartwig argues that the high cost of Amenhotep III’s ambitious building projects resulted in a consolidation of temple and royal grain ...
