Very very very helpful site to clear our doubts. Thank you so much.? Thank you so much? Many mathematicians talk about the elegance of mathematics, its intrinsic aesthetics and inner beauty. Simplicity and generality are valued.
There is beauty in a simple and elegant proof , such as Euclid 's proof that there are infinitely many prime numbers , and in an elegant numerical method that speeds calculation, such as the fast Fourier transform.
Hardy in A Mathematician's Apology expressed the belief that these aesthetic considerations are, in themselves, sufficient to justify the study of pure mathematics. He identified criteria such as significance, unexpectedness, inevitability, and economy as factors that contribute to a mathematical aesthetic. A theorem expressed as a characterization of the object by these features is the prize.
The popularity of recreational mathematics is another sign of the pleasure many find in solving mathematical questions. And at the other social extreme, philosophers continue to find problems in philosophy of mathematics , such as the nature of mathematical proof.
Most of the mathematical notation in use today was not invented until the 16th century. Modern notation makes mathematics much easier for the professional, but beginners often find it daunting. According to Barbara Oakley , this can be attributed to the fact that mathematical ideas are both more abstract and more encrypted than those of natural language.
Mathematical language can be difficult to understand for beginners because even common terms, such as or and only , have a more precise meaning than they have in everyday speech, and other terms such as open and field refer to specific mathematical ideas, not covered by their laymen's meanings. Mathematical language also includes many technical terms such as homeomorphism and integrable that have no meaning outside of mathematics.
Additionally, shorthand phrases such as iff for " if and only if " belong to mathematical jargon. There is a reason for special notation and technical vocabulary: mathematics requires more precision than everyday speech. Mathematicians refer to this precision of language and logic Ncert Solutions Class 10th Maths Chapter 5 Exercise 5.3 as "rigor".
Mathematical proof is fundamentally a matter of rigor. Mathematicians want their theorems to follow from axioms by means of systematic reasoning.
This is to avoid mistaken " theorems ", based on fallible intuitions, of which many instances have occurred in the history of the subject. Problems inherent in the definitions used by Newton would lead to a resurgence of careful analysis and formal proof in the 19th century.
Misunderstanding the rigor is a cause for some of the common misconceptions of mathematics. Today, mathematicians continue to argue among themselves about computer-assisted proofs. Since large computations are hard to verify, such proofs may be erroneous if the used computer program is erroneous. Axioms in traditional thought were "self-evident truths", but that conception is problematic.
Nonetheless mathematics is often imagined to be as far as its formal content nothing but set theory in some axiomatization, in the sense that every mathematical statement or proof could be cast into formulas within set theory. Mathematics can, broadly speaking, be subdivided into the study of quantity, structure, space, and change i. In addition to these main concerns, there are also subdivisions dedicated to exploring links from the heart of mathematics to other fields: to logic , to set theory foundations , to the empirical mathematics of the various sciences applied mathematics , and more recently to the rigorous study of uncertainty.
While some areas might seem unrelated, the Langlands program has found connections between areas previously thought unconnected, such as Galois groups , Riemann surfaces and number theory. Discrete mathematics conventionally groups together the fields of mathematics which study mathematical structures that are fundamentally discrete rather than continuous.
In order to clarify the foundations of mathematics , the fields of mathematical logic and set theory were developed.
Mathematical logic includes the mathematical study of logic and the applications of formal logic to other areas of mathematics; set theory is the branch of mathematics that studies sets or collections of objects. The phrase "crisis of foundations" describes the search for a rigorous foundation for mathematics that took place from approximately to The crisis of foundations was stimulated by a number of controversies at the time, including the controversy over Cantor's set theory and the Brouwer�Hilbert controversy.
Mathematical logic is concerned with setting mathematics within a rigorous axiomatic framework, and studying the implications of such a framework. Therefore, no formal system is a complete axiomatization of full number theory. Modern logic is divided into recursion theory , model theory , and proof theory , and is closely linked to theoretical computer science , [75] as well as to category theory. In the context of recursion theory, the impossibility of a full axiomatization of number theory can also be formally demonstrated as a consequence of the MRDP theorem.
Theoretical computer science includes computability theory , computational complexity theory , and information theory. Computability theory examines the limitations of various theoretical models of the computer, including the most well-known model�the Turing machine.
Complexity theory is the study of tractability by computer; some problems, although theoretically solvable by computer, are so expensive in terms of time or space that solving them is likely to remain practically unfeasible, even with the rapid advancement of computer hardware.
The deeper properties of integers are studied in number theory , from which come such popular results as Fermat's Last Theorem. The twin prime conjecture and Goldbach's conjecture are two unsolved problems in number theory. According to the fundamental theorem of algebra , all polynomial equations in one unknown with complex coefficients have a solution in the complex numbers, regardless of degree of the polynomial.
Consideration of the natural numbers also leads to the transfinite numbers , which formalize the concept of " infinity ". Another area of study is the size of sets, which is described with the cardinal numbers.
These include the aleph numbers , which allow meaningful comparison of the size of infinitely large sets. Many mathematical objects, such as sets of numbers and functions , exhibit internal structure as a consequence of operations or relations that are defined on the set. Mathematics then studies properties of those sets that can be expressed in terms of that structure; for instance number theory studies properties of the set of integers that can be expressed in terms of arithmetic operations.
Moreover, it frequently happens that different such structured sets or structures exhibit similar properties, which makes it possible, by a further step of abstraction , to state axioms for a class of structures, and then study at once the whole class of structures satisfying these axioms.
Thus one can study groups , rings , fields and other abstract systems; together such studies for structures defined by algebraic operations constitute the domain of abstract algebra.
By its great generality, abstract algebra can often be applied to seemingly unrelated problems; for instance a number of ancient problems concerning compass and straightedge constructions were finally solved using Galois theory , which involves field theory and group theory.
Another example of an algebraic theory is linear algebra , which is the general study of vector spaces , whose elements called vectors have both quantity and direction, and can be used to model relations between points in space. This is one example of the phenomenon that the originally unrelated areas of geometry and algebra have very strong interactions in modern mathematics.
Combinatorics studies ways of enumerating the number of objects that fit a given structure. The study of space originates with geometry �in particular, Euclidean geometry , which combines space and numbers, and encompasses the well-known Pythagorean theorem.
Trigonometry is the branch of mathematics that deals with relationships between the sides and the angles of triangles and with the trigonometric functions. The modern study of space generalizes these ideas to include higher-dimensional geometry, non-Euclidean geometries which play a central role in general relativity and topology. Quantity and space both play a role in analytic geometry , differential geometry , and algebraic geometry.
Convex and discrete geometry were developed to solve problems in number theory and functional analysis but now are pursued with an eye on applications in optimization and computer science. Within differential geometry are the concepts of fiber bundles and calculus on manifolds , in particular, vector and tensor calculus. Within algebraic geometry is the description of geometric objects as solution sets of polynomial equations, combining the concepts of quantity and space, and also the study of topological groups , which combine structure and space.
Lie groups are used to study space, structure, and change. Topology in all its many ramifications may have been the greatest growth area in 20th-century mathematics; it includes point-set topology , set-theoretic topology , algebraic topology and differential topology.
In particular, instances of modern-day topology are metrizability theory , axiomatic set theory , homotopy theory , and Morse theory. Other results in geometry and topology, including the four color theorem and Kepler conjecture , have been proven only with the help of computers.
Understanding and describing change is a common theme in the natural sciences , and calculus was developed as a tool to investigate it. Functions arise here as a central concept describing a changing quantity.
The rigorous study of real numbers and functions of a real variable is known as real analysis , with complex analysis the equivalent field for the complex numbers.
Functional analysis focuses attention on typically infinite-dimensional spaces of functions. One of many applications of functional analysis is quantum mechanics. Many problems lead naturally to relationships between a quantity and its rate of change, and these are studied as differential equations. Many phenomena in nature can be described by dynamical systems ; chaos theory makes precise the ways in which many of these systems exhibit unpredictable yet still deterministic behavior.
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 the professional specialty in which mathematicians work on practical problems; as a profession focused on practical problems, applied mathematics focuses on the "formulation, study, and use of mathematical models" in science, engineering, and other areas of mathematical practice.
In the past, practical applications have motivated the development of mathematical theories, which then became the subject of study in pure mathematics, where mathematics is developed primarily for its own sake. Thus, the activity of applied mathematics is vitally connected with research in pure mathematics. Applied mathematics has significant overlap with the discipline of statistics, whose theory is formulated mathematically, especially with probability theory.
Statisticians working as part of a research project "create data that makes sense" with random sampling and with randomized experiments ; [77] the design of a statistical sample or experiment specifies the analysis of the data before the data becomes available. When reconsidering data from experiments and samples or when analyzing data from observational studies , statisticians "make sense of the data" using the art of modelling and the theory of inference �with model selection and estimation ; the estimated models and consequential predictions should be tested on new data.
Statistical theory studies decision problems such as minimizing the risk expected loss of a statistical action, such as using a procedure in, for example, parameter estimation , hypothesis testing , and selecting the best.
In these traditional areas of mathematical statistics , a statistical-decision problem is formulated by minimizing an objective function , like expected loss or cost , under specific constraints: For example, designing a survey often involves minimizing the cost of estimating a population mean Class 10 Maths Ch 5 Ex 5.3 Release with a given level of confidence.
Computational mathematics proposes and studies methods for solving mathematical problems that are typically too large for human numerical capacity. Numerical analysis studies methods for problems in analysis using functional analysis and approximation theory ; numerical analysis includes the study of approximation and discretisation broadly with special concern for rounding errors.
Numerical analysis and, more broadly, scientific computing also study non-analytic topics of mathematical science, especially algorithmic matrix and graph theory. Other areas of computational mathematics include computer algebra and symbolic computation.
Arguably the most prestigious award in mathematics is the Fields Medal , [80] [81] established in and awarded every four years except around World War II to as many as four individuals. The Fields Medal is often considered a mathematical equivalent to the Nobel Prize. The Wolf Prize in Mathematics , instituted in , recognizes lifetime achievement, and another major international award, the Abel Prize , was instituted in The Chern Medal was introduced in to recognize lifetime achievement.
These accolades are awarded in recognition of a particular body of work, which may be innovational, or provide a solution to an outstanding problem in an established field. A famous list of 23 open problems , called " Hilbert's problems ", was compiled in by German mathematician David Hilbert.
This list achieved great celebrity among mathematicians, and at least nine of the problems have now been solved. A new list of seven important problems, titled the " Millennium Prize Problems ", was published in Only one of them, the Riemann hypothesis , duplicates one of Hilbert's problems. A solution to any of these problems carries a 1 million dollar reward.
