Descartes made one of the greatest advances in geometry by connecting algebra and geometry. A myth is that he was watching a fly on the ceiling when he conceived of locating points on a plane with a pair of numbers. Maybe this has something to do with the fact that he stayed in bed everyday until 11:00 A.M. Fermat also discovered coordinate geometry, but it's Descartes' version that we use today.\n\nCo-ordinate Geometry\nCo-ordinate geometry was introduced by Fermat and Descartes, ignoring rather than solving the foundational problems which had prevented the Greeks from taking this step (viz: the lack of any well understood number system which could account for incommensurable ratios). \nThis development is important to science because it makes geometry quantitative and permits the use of algebraic methods. Geometry must be quantitative for it to be useful in science and engineering, and algebraic methods permit more rapid development of mathematics than the less systematic (if more rigourous) methods required by the Greek axiomatic approach to geometry. \n \nIn co-ordinate geometry the points of a plane are labelled by 2 co-ordinates, its distances from the 2 axes, and familiar figures become the loci of points satisfying an algebraic equation. Thus, geometry is incorporated into algebra and the way is opened for the introduction of spaces of arbitrarily large dimension, important in mechanics. Curvature, in its simplest form, is a number attached to a surface at a point. The flatter the surface, the smaller the number (positive for a sphere, negative for a saddle-shaped surface). \nFrench mathematician who is often called the founder of the modern theory of numbers. Together with René Descartes, Fermat was one of the two leading mathematicians of the first half of the 17th century. Independently of Descartes, Fermat discovered the fundamental principle of analytic geometry. His methods for finding tangents to curves and their maximum and minimum points led him to be regarded as the inventor of the differential calculus. Through his correspondence with Blaise Pascal he was a co-founder of the theory of probability.\n\n\nhttp://people.bath.ac.uk/jm255/Geometry.htm this website will help u aswell!\n\nAnalytic geometry, also called coordinate geometry and earlier referred to as Cartesian geometry, is the study of geometry using the principles of algebra. Usually the Cartesian coordinate system is applied to manipulate equations for planes, lines, curves, and circles, often in two and sometimes in three dimensions of measurement. As taught in school books, analytic geometry can be explained more simply: it is concerned with defining geometrical shapes in a numerical way, and extracting numerical information from that representation. The numerical output, however, might also be a vector or a shape. Some consider that the introduction of analytic geometry was the beginning of modern mathematics.\n\nRené Descartes is popularly regarded as having introduced the foundation for the methods of analytic geometry in 1637 in the appendix titled Geometry of the titled Discourse on the Method of Rightly Conducting the Reason in the Search for Truth in the Sciences, commonly referred to as Discourse on Method. This work, written in his native language (French), and its philosophical principles, provided the foundation for calculus in Europe.\n\nThe relationship between algebra and geometry is nontrivial. There exist proofs of this relationship based on the theory of geometry and notions of geometric length.\n\n\n\nwrite this down and im finding more info ......

Apollonius was known as 'The Great Geometer'. His works had a very great influence on the development of mathematics and his famous book Conics introduced the terms parabola, ellipse and hyperbola.\nMore information on the site:\nhttp://www.gap-system.org/~history/Mathematicians/Apollonius.html

Johann Castillon used the name cardioid for the first time, in a paper in the Philosophical Transactions of the Royal Society (1741).\n\nHowever, he was not the first person who used it.  For example, it was studied by Roemer (1674) in an investigation for the best form of gear teeth. \n\nCardioid is a special case of limacon of Pascal: a family of curves studied and named after Etienne Pascal (1588-1640), father of Blaise Pascal (1623-1662). \n\nI don't know whether they originally used polar co-ordinates which followed after the Cartesian system developed by Descartes in 1637. But given that the general formula for the limacon is a ± bcos(theta) or a ± bsin(theta), it's certainly possible.

The use of grid lines on maps (latitude and longitude) was first suggested by the Greek astronomer Hipparcus about 300 years before Christ. He was the first who devised a method for fixing the location of places on earth by observation of the the sun, moon and stars. He worked out the mathematics of spherical trigonometry, which allowed the results of these observations to be plotted on an earth which he knew already to be a sphere.\n\nLatitude can be found easily by measuring the height of the sun at noon. The measurement of longitude is not so simple as you need an accurate clock.

Lagrange, Joseph (1736-1813)\nFrench mathematician and mathematical physicist who was the greatest mathematician of the eighteenth century. His work Mécanique Analytique (Analytical Mechanics) (1788) was a mathematical masterpiece. It contained clear, symmetrical notation and covered almost every area of pure mathematics. It was the first book of mechanics Eric Weisstein's World of Physics published without the use of a single diagram. Lagrange succeeded Euler as the director of the Berlin Academy.\n\nLagrange developed the calculus of variations Eric Weisstein's World of Math which was later expanded by Weierstraß. Lagrange also established the theory of differential equations, Eric Weisstein's World of Math and provided many new solutions and theorems in number theory, Eric Weisstein's World of Math including Wilson's theorem. Eric Weisstein's World of Math Lagrange's classic Théorie des fonctions analytiques laid some of the foundations of group theory, Eric Weisstein's World of Math anticipating Galois. Lagrange also invented the method of solvingdifferential equations Eric Weisstein's World of Math known as variation of parameters. Eric Weisstein's World of Math Lagrange commented that "I have always observed that the pretensions of all people are in exact inverse ratio to their merits; this is one of the axioms of morals" (Bell 1937, p. 160).

John Venn (August 4, 1834 - April 4, 1923) was an English mathematician/logician who invented the Venn diagram. \n\nBut Euler described numerous applications of Bernoulli's numbers, Fourier series, Venn diagrams, Euler's numbers, e and pi constants, continued fractions and integrals. \n\nEuler invented Euler circle.\n The nine point circle is a circle that can be constructed for any given triangle. It is named so because it passes through nine significant points, with six of them lying on the triangle itself: * the midpoints of the three sides,* the feet of the altitudes, * the midpoints of the portion of altitude between the vertices and the orthocenter.

Yes, it was Konrad Gesner.\n\nIt dates (we think) to 1565, when Konrad von Gesner, a Swiss-German naturalist, devised a wooden container filled with graphite for the purpose of drawing and writing. Refined, the invention—arguably history's most practically useful communication tool—became universally popular. If you keep a sharpener handy and can avoid breaking the point, you ostensibly can get about 45,000 words or 35 miles of sketched lines from the average pencil.\n\nIncidentally, the common term "lead pencil" is misleading (please excuse the play on spellings). At one time, graphite wrongly was considered to be synonymous with lead.

History\nAn odometer for measuring distance is described by Vitruvius around 27 and 23 BC. The actual invention may have been by Archimedes during the First Punic War. Hero of Alexandria describes a similar device in chapter 34 of his Dioptra. The device was also invented in ancient China by Zhang Heng (78 – 139).\n\nThe odometer of Vitruvius was based on chariot wheels of 4 feet (1.2 m) diameter turning 400 times in one Roman mile (about 1400 m). For each revolution a pin on the axle engaged a 400 tooth cogwheel thus turning it one complete revolution per mile. This engaged another gear with holes along the circumference, where pebbles (calculus) were located, that were to drop one by one into a box. The distance travelled would thus be given simply by counting the number of pebbles. Whether this instrument was ever built at the time is disputed. Leonardo da Vinci tried to build it according to the description but failed. In modern times, however, Andre Sleeswyk was able to make a working model using gears similar to the Antikythera mechanism as opposed to the traditional cogwheel.\n\nThe odometer as used in most modern systems, where separate gears control each digit, was invented by William Clayton with help from Orson Pratt. Clayton, a Mormon Pioneer, developed the odometer (dubbed the "roadometer") to keep track of wheel revolutions on the pioneer carts. The odometer had multiple gears, including one which turned every quarter-mile and one which turned every ten miles.

I'm assuming you mean Einstein, but I would have to go with Newton. He invented calculus and was absolutely revolutionary in developing elementary physics. Now, obviously Einstein was brilliant too, but at least he had a long background of physicists to build on. He stood on the shoulders of giants, one of which is newton.

a compass tells you which way is north. once you know where north is you can tell in which directions south, east, and west is.
