DEVELOPMENT OF MATHEMATICS

Contribution of eminent mathematicians to the development of mathematics - Aryabhatta,Brahmagupta, Baskara, Ramanujam, Euler, Euclid, Pythagoras, Gauss.

FAMOUS MATHEMATICIANS
ARCHIMEDES
Archimedes is remembered as the greatest mathematician of the ancient era. He contributed significantly in geometry regarding the areas of plane figures and the areas as well as volumes of curved surfaces. His works expected integral calculus almost 2000 years before it was invented by Sir Isaac Newton and Gottfried Wilhelm von Leibniz. He also proved that the volume of a sphere is equal to two-thirds the volume of a circumscribed cylinder. He regarded this as his most vital accomplishment. So, he desired that a cylinder circumscribing a sphere ought to be inscribed on his tomb. He found an approximate value of pi by circumscribing and inscribing a circle with regular polygons of 96 sides. His works have original ideas, impressive demonstrations and excellent computational techniques.
Some of these which have survived are:
ü on the sphere and cylinder
ü measurement of a circle
ü on conoids and spheroids
ü on spirals
ü on plane equilibriums
ü the sand reckoner
ü quadrature of the parabola
ü on floating bodies
ü stomachion

EUCLID
Euclid is the most famous mathematician of all time. "Euclid's Elements" is divided into 13 books.
ü the initial six are related to plane geometry
ü seven, eight and nine are pertaining to number theory
ü number ten is regarding Eudoxus's theory of irrational numbers
ü eleven to thirteen comprise of solid geometry
ü the last part throws light on the properties of five regular polyhedrons and an evidence that there can be maximum five of these

These Elements have an impressive clarity regarding the selection and order of the theorems and problems. There are minimum assumptions, less extraneous material and an excellent logic in the propositions. The Elements was first published in 1482.

The other works of Euclid which survive are:
ü optics
ü phenomena
ü on divisions of figures
ü data
The works of Euclid that have not survived are:
ü elements of music
ü book of fallacies
ü conics
ü porisms

ü surface loci
ARYA BHATA
The Indian mathematician and astronomer Aryabhata (476 A.D) is well known for his work. He was born at Pataliputra near Patna in Bihar. His most famous book is known as ―Aryabhrtia‖. In arithmetic, Algebra and place Geometry Aryabhata suggested humorous rules. A few important rules are enlisted below-
1. Area of triangle = base*height
2. The value of Pi =3.1456
3. Area of the circle (pi)2
4. Sum of AP =n/2[2a+(n-1)d

To sum up Aryabhata was really one of the greatest geniuses of his time in the field of mathematics and astronomy.

BRAHMAGUPTA
The ancient Indian astronomer brahmagupta is credited with having put forth the concept or zero for the fist time: brahmagupta is said to have been born in the year 598 A.D. at Bhillamala in Gujarat, western Indian. Much is known about brahmagupta’s early life, we are told that his name as a mathematician was well established when k.vyaghramukha of the chapa dynasty made him the court astronomer.
In the earlier Roman and Babylonian system of numeration, large number of characters was required to denote higher numerals. Thus enumeration and computation became unwieldy. For instance, as E the Roman system of numeration, the number thirty would have to be written as X; while as per the decimal system it would 30, further the number thirty three would be XXXIII as per roman system, would be 33 as per the decimal system. This also made computation easier.

BHASKARA
Bhashara or bhasharacharya is the most well known ancient Indian mathematician. He was born on 1114A.D. at bijjadabida in the sahyadari hill. He is famous for his book siddhantashiromani (1150 A.D). it is divided into four sections-leelavati (a book on arithmetic), bijaganita(algebra), goladnayaya(chapter on sphere- celestial globe), and granoganita (mathematics of a planets), leelavagti contains many interesting problems and was a very popular text book. He gave an example idea of what is now called ―Rolle’s theorem.‖ Unfortunately, later Indian mathematics did not take any notice of this. Five centuries, later newton and Leibnitz developed these subjects. As an astronomer bhaskara is renowned for his concept of tatakalikagati.

RAMANUJAN
Ramanujan was born in Brahmin family on December 22, 1887 at erode madras. He got his school education at kumbakoram. He won a scholarship in matriculation examination. His teachers were very much impressed by his injected and special gifted abilities in mathematics.
Hardy remarked: I had never seen anything the least like them before. A single look at them is enough to show that they could be written down by a mathematician of the highest class. His work thrown light on divergent series. Hypermetric series continued fraction, definite integrals. Partition functions, ecliptic functions the theory of numbers, fractional differentiation and highly composite numbers. 

MATHEMATICS AND ITS RELATIONSHIP WITH OTHER SUBJECTS


MATHEMATICS WITH SCIENCE
The knowledge and skills students engage within the various dimensions of mathematics support students in their studies of all aspects of science. In science students use measurement and number concepts particularly in data collection estimation of error analysis and modes of reporting. The mathematics domain supports students in developing number handling skills.
To collect the records interpret and display data appropriately, looking for patterns, drawing conclusions and making generalizations. Predictions for further investigations, extrapolations and interpolations may be made from their own experimental results or from reliable second and data.
MATHEMATICS WITH ARTS
The arts and mathematics involve students understanding of relationships between time and space, rhythm and line through the experience of these abstract concepts in various arts forms and mathematical ideas. Mathematically related aesthetic considerations, such as the golden ratio, are used across visual, performing and multi-modal arts forms.

MATHEMATICS WITH CIVICS AND CITIZENSHIP
The concepts developed in the study of mathematics are applicable to a range of civic and citizenship understandings. Mathematical structure and working play essential roles in key aspects of our society as well as key civics concepts. Particular aspects of civics and citizenship require mathematical understanding, including concepts of majority rule, absolute majority, one vote one value representation and proportional voting systems.

MATHEMATICS WITH COMMUNICATION
Mathematics structure and working mathematically play essential roles in understanding natural and human worlds. Developments of the languages of mathematics are crucial to its practical application. Students learn to use the language and concepts of mathematics both within the discipline itself and also its applications to modelling and problem solving across the other domains. In this process they employee a range of communication tools for illustrating relationships and displaying results such as Venn diagrams and tree diagrams.
MATHEMATICS AND PHYSICS

All the physical laws, laws of motion, laws of lever and pulleys, laws of refraction and reflection, laws of magnetization, laws of  electric current  movement of the earth and planets and law of quantum energy can only by understood and applied with the  help of the understanding of Mathematics.
The lenses and other equipment’s used in microscope, telescope, photographic camera movie can only be made useful and workable with the help of intensity, power andarrangement decided by the basic principles of Mathematics.

MATHEMATICS AND CHEMISTRY
             The Study of compounds, mixtures, laws of chemical combination and the study of molecular or atomic structures, chemical names of formula and chemical equations all are based on the laws of Mathematics. In the preparation of different gases and chemical products like bleaching powder, salts, acids, medicines and other day to use products, we need exact measurements in terms of weight, ratios and other calculations.
         In this way it is no exaggeration in saying that Mathematics is used in the study of chemistry right from a petty chemical reaction to the preparation of chemical fuels of modern rockets and bombs.

MATHEMATICS  AND  BOTANY – ZOOLOGY
        The cellular construction of animals and vegetables, heredity, process of reproduction, balanced diet and similar other topics need the knowledge of Mathematics. In any organism if we try to study the anatomical structure and pattern of definite growth and development, we have to take the help of the subject Mathematics. The graphs and statistical concepts used in these branches can also reveal the need of Mathematics or Geometry.
MATHEMATICS AND MEDICAL SCIENCE

In preparation of the doses of medicines one has to take it toaccount the mechanism of measurement which is not possiblewithout Mathematics.
MATHEMATICS AND ENGINEERING

Mathematics is the base of all the Engineering, Surveying and measurements which help the Science of Engineering. To construct large bridges, plan the network of canals and dams, extend railway lines across the wide forests and lofty mountains, control the floods and establish the heavy industry.
Actually the relationship between Mathematics and Science is just like the relationship between the body and its soul. Body (science) has no meaning without its soul (Mathematics).

MATHEMATICS WITH ENGLISH
Mathematics, including the use of conjectures and proof, has clear links to the development of structures and coherent argument in speaking writing. Mathematical structure is strongly related to semantics syntax and language and to the use of propositions and quantifiers embedded in principled argument in natural languages.

MATHEMATICS WITH HEALTH AND PHYSICAL EDUCATION
In health and physical education, mathematics provides tools and procedures which can be used to model situations and solve problems in areas such as:
1. Scoring different sporting events involving time distance, weight and number as variables.
2. Calculating percentage improvement in results from data collected through fitness testing or performance in physical activities.

MATHEMATICS WITH HUMANITIES-ECONOMICS
The economics and mathematics are related through the use of mathematics to model a broad range of economic, political and social phenomena. Examples include the use of statistical modelling and analysis in a census, sampling populations to predict election outcomes, and modelling and forecasting economic indicators such as the consumer price index and business confidence.

MATHEMATICS WITH  GEOGRAPHY
The application of mathematical skills plays a key role in financial literacy, in particular the use of ratio, proportion and percentage in related calculations such as percentage increase or decrease in price of a commodity or personal income. Mathematics provides the basis of measurement, scale and spatial representation used in maps and plans. Geography also uses the concepts of direction, length, angle and bearing, gradient and contour and area.


UNIT – I NATURE AND DEVELOPMENT OF MATHEMATICS,

NATURE, CHARACTERISTICS AND OF MATHEMATICS

MEANING OF MATHEMATICS

Mathematics is commonly defined as the study of patterns of structure, chance, and space; more informally, one might say it is the study of figures and numbers. In the formalist view, it is the investigation of axiomatically defined abstract structures using logic and mathematical notation; other views are described in philosophy of mathematics.

DEVELOPMENT OF MATHEMATICS

The earliest records of mathematics show it arising in response to practical needs in agriculture, business, and industry. In Egypt and Mesopotamia, where evidence dates from the 2d 3d millennia b.c., it was used for surveying and menstruation; estimates of the value of pi are found in both locations.

CHARACTERISTICS OF MATHEMATICS
Children may exhibit feelings in insecurity, as well as fears of failure, punishment, ridicule, or stigmatizing labels. Children with math anxiety may also have a negative attitude or negative emotional reaction to math. Teachers need to provide students with experiences that they will be successful in, in order to promote a more positive attitude. They learning bridge or strategies are good ways to help prevent the early development of math anxiety.

LOGICAL SEQUENCE IN MATHEMATICS
The problem is predicting the next term of a partially specified sequence. The user shall input the rest few terms of a mathematical sequence. The expert system will rest try you understand the pattern and using the found pattern it would predict the next term.

INTEGER SEQUENCES
Integer sequences are the most commonly seen sequences. For integer sequences, it’s the addition, subtraction and multiplication operators that play the major role in Xing up in the function f. so, in order to discover the function f, we need to perform various operations on the integers that are the first few given terms of the sequence.
For example, consider the sequence 3;7;11;15;…… the way this sequence is understood is by taking the deference between adjacent terms of the sequences.
STRUCTURE OF MATHEMATICS
The focus of my presentation will be on such structural aspects of mathematics that are known or likely to cause problems or challenges for the process of learning mathematics, and hence for its teaching. I shall interpret the term ―the structure of mathematics‖ in a somewhat broad sense, by taking into account also the nature of mathematics and its characteristics as a discipline and not solely its architectural features as reflected in one or more possible construction(s) of edifice.


ABSTRACTION
Mathematical thinking often begins with the process of abstraction-that is, noticing a similarity between two or more objects or events. Aspects that they have in common, whether concrete or hypothetical can be represented by symbols such as numbers, letters, other marks, diagrams, geometrical constructions, or even words.
Whole numbers are abstractions that represent the size of sets of things and events or the order of things within a set. The circle as a concept is an abstraction derived from human faces, flowers, wheels, or spreading ripples; the letter a may be an abstraction for the surface area of objects of any shape, for the acceleration of all moving objects, or for all objects process of addition, whether one is adding apples or oranges, hours, or miles per hour.

SYMBOLISM OF MATHEMATICS
The precise opposite is the case. Civilization advances by extending the number of important operations which we can perform without thinking about them. Operations of thought are like cavalry charges in a battle-they are strictly limited in number, they require fresh horses, and must only be made at decisive moments.
The symbolism of mathematics is in truth the outcome of the general ideas which dominate the science.

MATHEMATICS AS SCIENCE OF MEASUREMENT
Mathematics and science education, including the metric system of measurement, will be strengthened throughout the system, especially in the early grades.

Aristotle - The science of quantity. In Aristotle's classification of the sciences, discrete quantities were studied by arithmetic, continuous quantities by geometry.
Benjamin Peirce –“Mathematics is the science that draws necessary conclusions”
Bertrand Russell –“All Mathematics is Symbolic Logic”.
Oxford English Dictionary –“The abstract science which investigates deductively the conclusions implicit in the elementary conceptions of spatial and numerical relations, and which includes as its main divisions geometry, arithmetic, and algebra”.
American Heritage Dictionary  -“The study of the measurement, properties, and relationships of quantities and sets, using numbers and symbols”.
Encyclopaedia Britannica-“The science of structure, order, and relation that has evolved from elemental practices of counting, measuring, and describing the shapes of objects”.
Galileo Galilee - “The universe cannot be read until we have learned the language and become familiar with the characters in which it is written”. It is written in mathematical language, and the letters are triangles, circles and other geometrical figures, without which means it is humanly impossible to comprehend a single word. Without these, one is wandering about in a dark labyrinth.
Carl Friedrich Gauss  - "The Queen of the Sciences"
Benjamin Peirce   - “The science that draws necessary conclusions".

Albert Einstein  - "As far as the laws of mathematics refer to reality, they are not certain; and as far as they are certain, they do not refer to reality."
