CORRESPONDENT SPEAKS

In today’s changing scenario, there is an increasing necessity of empowering the students through innovative education. They should also be made aware of their rights and responsibilities. In the present system, students gain mere subject knowledge through the educational institutions. A healthy educational environment will cultivate positive personality among the students. “Students of today are the citizens of tomorrow” and so, they should be motivated towards the right direction. This magazine encompassing Puzzles, Aptitude questions, Vedic Maths and many more will create flourishing impact in the mind of the readers. I wish all the budding mathematics genius, a good luck.

EDITOR’S DESK

A glimpse at the happenings during the academic year (201 3-2014) gives us a sense of pride and satisfaction.

This is the story of a queen. We have heard the story of a Greek king who turned every objects he touched into gold. Our queen is different! She never changed anything to gold, but here is a magic touch that altered the course of history. This queen is none other than ‘Mathematics’- the undisputed queen of all sciences! We cannot imagine a single branch of science where the influence of mathematics is not felt.

Over the years, mathematics has grown to be the strongest scientific discipline ever, and some great mathematicians paved the way for its present glory.

The board hole heartedly appreciate and acknowledges the creativity and assistance offe red by the students of the department in bringing out this magazine.

Budding Mathematician

Galois was born on 25 October 1811 to Nicolas-Gabriel Galois and Adélaïde-Marie (born Demante). He became bored with his studies and,Galois at 1811 the- 1832age of 14, he began to take a serious interest in mathematics.

Budding Mathematician In the following year Galois's first paper, on continued fractions, was published. It was at around the same time that he began making fundamental discoveries in the theory of polynomial equations. He submitted two papers on this topic to the Academy of Sciences. Augustin Louis Cauchy refered these papers, Cauchy recognized the importance of Galois's work, and that he merely suggested combining the two papers into one in order to enter it in the competition for the Academy's Grand Prize in Mathematics. Despite the lost memoir, Galois published three papers that year, one of which laid the foundations for Galois theory. The second one was about the numerical resolution of equations (root finding in modern terminology). The third was an important one in , in which the concept of a finite field was first articulated. Galois, always a radical, joined the National Guard, but was subsequently imprisoned in 1831 after proposing a toast interpreted as a threat to the King. On the night before his death in 1832, Galois wrote a letter to his friend Auguste Chevalier, setting forth his discovery of the connection between group theory and the solutions of polynomial equations by radicals (Galois 1959). After writing the letter, Galois was shot to death in his intestine in a gun fight. Cauchy

Cauchy was the son of Louis François Cauchy (1760–1848) and Marie-Madeleine Desestre. In 1805 he placed second out of 293 applicants on this exam, and he was admitted. One of the main purposes of this school was to give future civil and military engineers a high-level scientific and mathematical education

Engineering days

After finishing school in 1810, Cauchy accepted a job as a junior engineer in Cherbourg, he still found time to prepare three mathematical manuscripts, which he submitted to the Première Classe (First Class) of the Institute de France. Cauchy's first two manuscripts were accepted; the third one was rejected. The next three years Augustin- Louis was mainly on unpaid sick leave, and spent his time quite fruitfully, working on mathematics (on the related topics of symmetric functions, the symmetric group and the theory of higher-order algebraic equations).

Professor at École Polytechnique

In November 1815 one of his great successes at that time was the proof of Fermat's theorem. When Cauchy was 28 years old, Alexandre Laurent Cauchy, who became a president of a division of the court of appeal in 1847, and a judge of the court of cassation in 1849; and Eugène François Cauchy, a publicist who also wrote several mathematical works.

The conservative political climate that lasted until 1830 suited Cauchy perfectly. In 1824 Louis XVIII died, and was succeeded by his even more reactionary brother Charles X. During these years Cauchy was highly productive, and published one important mathematical treatise after another. He received cross appointments at the Collège de France, and the Faculté des Sciences of the University.

Riemann

Bernhard seems to have been a good, but not outstanding, pupil who worked hard at the classical subjects such as Hebrew and theology. On one occasion he lent Bernhard Legendre's book on the theory of numbers and Bernhard read the 900 page book in six days. In the spring of 1846 Riemann enrolled at the University of Göttingen. His father had encouraged him to study theology and so he entered the theology faculty. This was granted, however, and Riemann then took courses in mathematics from Moritz Stern and Gauss.

Gauss did lecture to Riemann but he was only giving elementary courses and there is no evidence that at this time he recognized Riemann’s genius. Riemann moved Berlin University in the spring of 1847 to study under Steiner, Jacobi, Dirichlet and Eisenstein. This was an important time for Riemann. He learnt much from Eisenstein and discussed using complex variables in elliptic function theory.

Riemann's work always was based on intuitive reasoning which fell a little below the rigor required to make the conclusions watertight. However, the brilliant ideas which his works contain are so much clearer because his work is not overly filled with lengthy computations. It was during his time at the University of Berlin that Riemann worked out his general theory of complex variables that formed the basis of some of his most important work.

In 1849 he returned to Göttingen and his Ph.D. thesis, supervised by Gauss, was submitted in 1851. Riemann's thesis studied the theory of complex variables and, in particular, what we now call Riemann surfaces. It therefore introduced topological methods into complex function theory.

On Gauss's recommendation Riemann was appointed to a post in Göttingen and he worked for his Habilitation, the degree which would allow him to become a lecturer. He spent thirty months working on his Habilitation dissertation which was on the represent ability of functions by trigonometric series. He gave the conditions of a function to have an integral, what we now call the condition of Riemann integrability.

Augustus De Morgan

Augustus De Morgan was a British mathematician born on 27 th June 1806 in Madras, India. His father was posted there with the East India Company. His mathematical skill was unnoticed till he was fourteen when a friend of the family discovered a mathematical drawing made by him using a ruler and compass.

In 1823, De Morgan enrolled in Trinity College, Cambridge. He also held a passion for music which became his recreation at Cambridge as well. De Morgan was a very capable mathematics teacher. His way of teaching was highly appreciated by the students. His ability to illustrate mathematical principles with thorough brilliant dexterity outweighed the other teaching methods used at the time. De Augustus De Morgan was actively involved in the promotion of an Indian mathematician Ramchundra who was a self-taught actuary.

De Morgan was a very good writer. He corresponded with William Hamilton for almost twenty five years often discussing mathematical matters and other subjects in general. It is said that if the works of De Morgan were ever to be collected they would form a small library. He wrote for many including his writings for the Useful Knowledge Society.

He also contributed to a Philosophical Society at Cambridge with four memoirs on basis of algebra and four on formal logic. His best known works in algebra include ‘Trigonometry and Double Algebra’ which was published in 1849. De Morgan was the discoverer of relation algebra. He framed the ‘De Morgan’s Laws’ and was the creator of the term ‘mathematical induction’. During his life he wrote over 700 articles for the Penny Cyclopedia. Another famous work published in it was De Morgan’s ‘The Differential and Integral Calculus’.

Brook Taylor

Brook Taylor was born on 18th August 1685 in Edmonton, England. His parents John Taylor and mother Olivia Tempest had very stable financial condition. Taylor was home tutored before starting his studies in St. John’s College, Cambridge. He acquired the degrees of LLB in 1709 and LLD in 1714.

He was interested in Art and Music but his first love was mathematics. He portrayed exceptional abilities in mathematics by writing a very important paper even before his graduation. It was however published later in 1914 in the Philosophical Transactions of the Royal Society. It gave the explanation of the oscillation of a body.

Taylor provided the solution to the ‘Kepler’s Law’ to Machin in 1912. Noticing Taylor’s extraordinary expertise in the subject, he was elected as a member of the Royal Society by Machin and Keill. In 1714, Brook Taylor became the secretary of the Royal Society.

The time that Taylor spent as the secretary of the Royal Society proved to be very fruitful to the world of mathematics. He wrote two very significant books ‘Method us incrementorum directa et inversa’ and ‘Linear Perspective’ which were published in 1715. The second editions of these books came out in 1717 and 1719. Taylors’ paper on ‘Linear Perspective’ contained the most accurate principals of art as compared to his antecedents.

He added a new branch in mathematics known as the ‘Calculus of Finite Differences’. He was the one to invent ‘Integration of Parts’ and also a series called the ‘Taylor’s Expansion’. The Taylor’s Theorem is based on the letter written by him to Machin in which he tells about the origination of this idea.

Daniel Bernoulli

Daniel Bernoulli was a Swiss mathematician born on 29th January 1700 in Groningen, Netherlands. He belonged to a family of mathematicians. His father Johann Bernoulli was one of the first developers of calculus and his uncle and older brother are known as ‘by far the ablest of the younger Harpers’. At the age of 7, Daniel expressed his desire to study mathematics but his father encouraged him to study business instead. Daniel agreed on the condition that his father would tutor him in mathematics.

In 1724, Daniel went to St. Petersburg to fill the post as Professor of Mathematics. ‘Exercitationes’ meaning ‘Mathematical Exercises’ was published in 1724. This was his first mathematical work. One of his most notable works is ‘Hydrodynamique’ which was published in 1738. After this he also wrote a memoir stating the theory of tides. It received a prize from the French Academy. He wrote several papers containing mechanical questions concerned with vibration of strings and works of Brook Taylor and Jean le Rond d’Alembert. He made discoveries on the motion of fluids. A significant discovery was the connection between the speed of the flow of blood and its pressure. Daniel did an experiment in which he set up an apparatus showing the relation between the two values. This became the normal way of measuring blood pressure; by piercing the artery with pointed glass tubes. It was later when the less painful method was used.

However this method of Bernoulli is used to measure the airspeed of a plane. He also wrote the ‘Specimen theories novae de mensura sortis’ meaning the ‘Exposition of a New Theory on the Measurement of Risk’. He also solved a statistical problem in 1766 in which he analyzed smallpox disease and transience to demonstrate the efficiency of vaccination. It was Bernoulli who discovered the fluid equation. It is now used as 1/2pu to the power of 2+p=constant. Bernoulli also made significant contributions to physics such as his formulation of the kinetic theory of gases and using this he explained the Boyles Law. He also did a lot of work on elasticity and beams. The Bernoulli Principle is highly useful in aerodynamics.

Mother’s Love

Mother, the incarnation of god, Greater than any other lord A person of admiration For all creations In every situation she has to know-how To shower her love Leads us to the path of Victory For us to make history Of course, she wants us to keep prospering But it’s hard to hear her goading Expects nothing, But drives us to keep achieving From her, world learns The art of love and affection A person to invigorate For everybody to rejuvenate Never can we find A person of her kind For us she’s a treasure Whom I write about with pleasure

Faces in a Class Room

Alternative faces:

They see, hear and follow everything which the teacher speaks and writes on the black board. Semi alternative faces: They can see and hear everything, but they do not understand due to lack of attention. Anti-Attentive faces: They are also called absent minded. They neither try to see and hear nor do they try to follow anything. Idle-Faces: They do nothing and see nothing. ”nothing” can be said to be their motto. They come to class blank and they go out of it BLANK.

Pretending faces:

They constantly smile when the teacher smiles and shake their heads when the teacher explains something as if they have understood and followed everything. Sleeping faces: Generally, they are found among the back benches in the class. They hope to remain unobserved while they sit with their eyes shut. Semi- sleeping faces: They are found among the middle or side benches in the class. They are constantly opening and closing their eyes as they feel sleepy but cannot sleep. Nodding faces: They feel sleepy and they put their heads down but after a short time they raise their heads so that they might not be caught by the teacher.

Fear of Number

Fear of number is real They carry adding machines on their backs And loaded numbered guns Divide and subtract from families and everyone With two times the pleasure two times the fun Double their trouble on the run You cannot escape the digits on your hands and toes They are counting on you to pull them through Children fear math and number like the plague Run from them at multiple fractions of a second Proof!...like zero,(is that a real name and number? ),they are gone Figures hide behind accountants glasses Not to be divisive or derisive Or taken down in dividends I think they’re out to get you In the end they have no Something’s don’t add up You can count on that Fear of numbers BY
