Mathematician


mathematician is a person with an extensive knowledge of mathematics who uses this knowledge in their work, typically to solve mathematical problems. Mathematics is concerned with numbersdatacollectionquantitystructurespace, and change.
Mathematicians involved with solving problems outside of pure mathematics are called applied mathematicians. Applied mathematicians are mathematical scientists who, with their specialized knowledge and professional methodology, approach many of the imposing problems presented in related scientific fields. With professional focus on a wide variety of problems, theoretical systems, and localized constructs, applied mathematicians work regularly in the study and formulation of mathematical models.
The discipline of applied mathematics concerns itself with mathematical methods that are typically used in science, engineering, business, and industry; thus, "applied mathematics" is a mathematical science with specialized knowledge. The term "applied mathematics" also describes theprofessional specialty in which mathematicians work on problems, often concrete but sometimes abstract. As professionals focused on problem solving, applied mathematicians look into the formulation, study, and use of mathematical models in scienceengineeringbusiness, and other areas of mathematical practice.

Jules Henri Poincaré (French: [ʒyl ɑ̃ʁi pwɛ̃kaʁe];[2] 29 April 1854 – 17 July 1912) was a French mathematiciantheoretical physicist,engineer, and a philosopher of science. He is often described as a polymath, and in mathematics as The Last Universalist, since he excelled in all fields of the discipline as it existed during his lifetime.
As a mathematician and physicist, he made many original fundamental contributions to pure and applied mathematicsmathematical physics, and celestial mechanics. He was responsible for formulating the Poincaré conjecture, which was one of the most famousunsolved problems in mathematics until it was solved in 2002–2003. In his research on the three-body problem, Poincaré became the first person to discover a chaotic deterministic system which laid the foundations of modern chaos theory. He is also considered to be one of the founders of the field of topology.
Poincaré made clear importance of paying attention to the invariance of laws of physics under different transformations, and was the first to present the Lorentz transformations in their modern symmetrical form. Poincaré discovered the remaining relativistic velocity transformations and recorded them in a letter to Dutch physicist Hendrik Lorentz (1853–1928) in 1905. Thus he obtained perfect invariance of all of Maxwell's equations, an important step in the formulation of the theory of special relativity.
The Poincaré group used in physics and mathematics was named after him.

Egyptian Mathematics.

Egyptian mathematics is the mathematics that was developed and used in Ancient Egypt from ca. 3000 BC to ca. 300 BC.


Written evidence of the use of mathematics dates back to at least 3000 BC with the ivory labels found at Tomb Uj at Abydos. These labels appear to have been used as tags for grave goods and some are inscribed with numbers.[1] Further evidence of the use of the base 10 number system can be found on for instance the Narmer Macehead which depicts offerings of 400,000 oxen, 1,422,000 goats and 120,000 prisoners.[2]
The evidence of the use of mathematics in the Old Kingdom (ca 2690–2180 BC) is scarce, but can be deduced from for instance inscriptions on a wall near a mastaba in Meidum which gives guidelines for the slope of the mastaba.[3] The lines in the diagram are spaced at a distance of one cubit and show the use of that unit of measurement.[1]
The earliest true mathematical documents date to the 12th dynasty (ca 1990–1800 BC). The Moscow Mathematical Papyrus, the Egyptian Mathematical Leather Roll, the Lahun Mathematical Papyri which are a part of the much larger collection of Kahun Papyri and the Berlin Papyrus all date to this period. The Rhind Mathematical Papyrus which dates to theSecond Intermediate Period (ca 1650 BC) is said to be based on an older mathematical text from the 12th dynasty.[4]
The Moscow Mathematical Papyrus and Rhind Mathematical Papyrus are so-called mathematical problem texts. They consist of a collection of problems with solutions. These texts may have been written by a teacher or a student engaged in solving typical mathematics problems.[1]
An interesting feature of Ancient Egyptian mathematics is the use of unit fractions. The Egyptians used some special notation for fractions such as 1/2, 1/3 and 2/3 and in some texts for 3/4, but other fractions were all written as unit fractions of the form 1/n or sums of such unit fractions. Scribes used tables to help them work with these fractions. The Egyptian Mathematical Leather Roll for instance is a table of unit fractions which are expressed as sums of other unit fractions. The Rhind Mathematical Papyrus and some of the other texts contain 2/n tables. These tables allowed the scribes to rewrite any fraction of the form \frac{1}{n} as a sum of unit fractions.[1]
During the New Kingdom (ca 1550–1070 BC) mathematical problems are mentioned in the literary Papyrus Anastasi I, and the Papyrus Wilbour from the time of Ramesses III records land measurements. In the worker's village of Deir el-Medina several ostraca have been found that record volumes of dirt removed while quarrying the tombs.[1][4]
