Pierre de Fermat - Wikipedia, the free encyclopedia
Pierre de Fermat ( French pronunciation: [pjɛːʁ dəfɛʁˈma] ; 17 [ 1 ] August 1601 or 1607/8 [ 2 ] – 12 January 1665) was a French lawyer at the Parlement of Toulouse , France , and an amateur mathematician who is given credit for early developments that led to infinitesimal calculus , including his adequality . In particular, he is recognized for his discovery of an original method of finding the greatest and the smallest ordinates of curved lines, which is analogous to that of the then unknown differential calculus , and his research into number theory . He made notable contributions to analytic geometry , probability , and optics . He is best known for Fermat's Last Theorem , which he described in a note at the margin of a copy of Diophantus ' Arithmetica . [ edit ] Life and work Fermat was born in Beaumont-de-Lomagne , Tarn-et-Garonne , France; the late 15th century mansion where Fermat was born is now a museum.

He has been dubbed the 'Father of Modern Philosophy', and much subsequent Western philosophy is a response to his writings, [ 4 ] [ 5 ] which are studied closely to this day.
Applied mathematics is a branch of mathematics that 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 the professional specialty in which mathematicians work on practical problems; as a profession focused on practical problems, applied mathematics focuses on the formulation and study of mathematical models .

Embrace Your Inner Statistician! | The Big Picture
You are a probability machine, a statistician, a mathematical wizard. You may not be aware of this simple fact, but its true: Every day, you engage in a series of probabilistic decision-making. You choose based on the probabilities of various outcomes taking place.
In statistics , regression analysis includes many techniques for modeling and analyzing several variables, when the focus is on the relationship between a dependent variable and one or more independent variables . More specifically, regression analysis helps one understand how the typical value of the dependent variable changes when any one of the independent variables is varied, while the other independent variables are held fixed. Most commonly, regression analysis estimates the conditional expectation of the dependent variable given the independent variables — that is, the average value of the dependent variable when the independent variables are held fixed. Less commonly, the focus is on a quantile , or other location parameter of the conditional distribution of the dependent variable given the independent variables.

Jessica Simpson What has mathematics got to do with beauty? Actually, a lot. Physical attraction depends on ratio . Our attraction to another person's body increases if that body is symmetrical and in proportion. Likewise, if a face is in proportion, we are more likely to notice it and find it beautiful.
The Math Behind the Beauty
If you ask mathematicians what they do, you always get the same answer. They think. They think about difficult and unusual problems.

Jacco vanderKooij on With revolutionary services coming out at a high pace we need to change the way we train our sales professionals to ramp them quicker make ...Version for printing It is often thought that mathematics can only develop after a civilisation has developed some form of writing. Although not easy for us to understand today, many civilisations reached highly advanced states without ever developing written records. Now of course it is difficult for us to know much about such civilisations since there is no written record to be studied today. This article looks at the mathematical achievements of one such civilisation. The civilisation we discuss, which does not appear to have found a need to develop writing, is that of the Incas.

A Fibonacci spiral created by drawing circular arcs connecting the opposite corners of squares in the Fibonacci tiling; this one uses squares of sizes 1, 1, 2, 3, 5, 8, 13, 21, and 34. See golden spiral . (sequence A000045 in OEIS ). The Fibonacci sequence is named after Leonardo of Pisa , who was known as Fibonacci.
