A.P.J. Abdul Kalam

PRESIDENT OF INDIA

A.P.J. Abdul Kalam, in full Avul Pakir Jainulabdeen Abdul Kalam, (born October 15, 1931, Rameswaram, India—died July 27, 2015, Shillong), Indian scientist and politician who played a leading role in the development of India's missile and nuclear weapons programs. He was president of India from 2002 to 2007.

Kalam earned a degree in aeronautical engineering from the Madras Institute of Technology and in 1958 joined the Defence Research and Development Organisation (DRDO). He soon moved to the Indian Space Research Organisation, where he was project director of the SLV-III, India’s first indigenously designed and produced satellite launch vehicle. Rejoining DRDO in 1982, Kalam planned the program that produced a number of successful missiles, which helped earned him the nickname “Missile Man.”

From 1992 to 1997 Kalam was scientific adviser to the defense minister, and he later served as principal scientific adviser (1999–2001) to the government with the rank of cabinet minister. His prominent role in the country’s 1998 nuclear weapons tests established Kalam as a national hero, although the tests caused great concern in the international community. In 1998 Kalam put forward a countrywide plan called Technology Vision 2020, which he described as a road map for transforming India from a less-developed to a developed society in 20 years. The plan called for, among other measures, increasing agricultural productivity, emphasizing technology as a vehicle for economic growth, and widening access to health care and education.

In 2002 India’s ruling National Democratic Alliance (NDA) put forward Kalam to succeed outgoing President Kocheril Raman Narayanan. Kalam was nominated by the Hindu nationalist (Hindutva) NDA even though he was Muslim, and his stature and popular appeal were such that even the main opposition party, the Indian National Congress, also proposed his candidacy. Kalam easily won the election and was sworn in as India’s 11th president, a largely ceremonial post, in July 2002. He remained committed to using science and technology to transform India into a developed country. In 2007 Kalam left office and was succeeded by Pratibha Patil, the country’s first woman president.

Kalam wrote several books, including an autobiography, Wings of Fire (1999). Among his numerous awards were two of the country’s highest honours, the Padma Vibhushan (1990) and the Bharat Ratna (1997).

Engineering, the application of science to the optimum conversion of the resources of nature to the uses of humankind. The field has been defined by the Engineers Council for Professional Development, in the United States, as the creative application of “scientific principles to design or develop structures, machines, apparatus, or manufacturing processes, or works utilizing them singly or in combination; or to construct or operate the same with full cognizance of their design; or to forecast their behaviour under specific operating conditions; all as respects an intended function, economics of operation and safety to life and property.” The term engineering is sometimes more loosely defined, especially in Great Britain, as the manufacture or assembly of engines, machine tools, and machine parts.

The words engine and ingenious are derived from the same Latin root, ingenerare, which means “to create.” The early English verb engine meant “to contrive.” Thus, the engines of war were devices such as catapults, floating bridges, and assault towers; their designer was the “engine-er,” or military engineer. The counterpart of the military engineer was the civil engineer, who applied essentially the same knowledge and skills to designing buildings, streets, water supplies, sewage systems, and other projects.

Associated with engineering is a great body of special knowledge; preparation for professional practice involves extensive training in the application of that knowledge. Standards of engineering practice are maintained through the efforts of professional societies, usually organized on a national or regional basis, with all members acknowledging a responsibility to the public over and above responsibilities to their employers or to other members of their society.

The function of the scientist is to know, while that of the engineer is to do. Scientists add to the store of verified systematized knowledge of the physical world, and engineers bring this knowledge to bear on practical problems. Engineering is based principally on physics, chemistry, and mathematics and their extensions into materials science, solid and fluid mechanics, thermodynamics, transfer and rate processes, and systems analysis.

Unlike scientists, engineers are not free to select the problems that interest them. They must solve problems as they arise, and their solutions must satisfy conflicting requirements. Usually, efficiency costs money, safety adds to complexity, and improved performance increases weight. The engineering solution is the optimum solution, the end result that, taking many factors into account, is most desirable. It may be the most reliable within a given weight limit, the simplest that will satisfy certain safety requirements, or the most efficient for a given cost. In many engineering problems the social costs are significant.

Engineers employ two types of natural resources—materials and energy. Materials are useful because of their properties: their strength, ease of fabrication, lightness, or durability; their ability to insulate or conduct; their chemical, electrical, or acoustical properties. Important sources of energy include fossil fuels (coal, petroleum, gas), wind, sunlight, falling water, and nuclear fission. Since most resources are limited, engineers must concern themselves with the continual development of new resources as well as the efficient utilization of existing ones.

History Of Engineering

The first engineer known by name and achievement is Imhotep, builder of the Step Pyramid at Ṣaqqārah, Egypt, probably about 2550 BCE. Imhotep’s successors—Egyptian, Persian, Greek, and Roman—carried civil engineering to remarkable heights on the basis of empirical methods aided by arithmetic, geometry, and a smattering of physical science. The Pharos (lighthouse) of Alexandria, Solomon’s Temple in Jerusalem, the Colosseum in Rome, the Persian and Roman road systems, the Pont du Gard aqueduct in France, and many other large structures, some of which endure to this day, testify to their skill, imagination, and daring. Of many treatises written by them, one in particular survives to provide a picture of engineering education and practice in classical times: Vitruvius’s De architectura, published in Rome in the 1st century CE, a 10-volume work covering building materials, construction methods, hydraulics, measurement, and town planning.

In construction, medieval European engineers carried technique, in the form of the Gothic arch and flying buttress, to a height unknown to the Romans. The sketchbook of the 13th-century French engineer Villard de Honnecourt reveals a wide knowledge of mathematics, geometry, natural and physical science, and draftsmanship.

In Asia, engineering had a separate but very similar development, with more and more sophisticated techniques of construction, hydraulics, and metallurgy helping to create advanced civilizations such as the Mongol empire, whose large, beautiful cities impressed Marco Polo in the 13th century.

Civil engineering emerged as a separate discipline in the 18th century, when the first professional societies and schools of engineering were founded. Civil engineers of the 19th century built structures of all kinds, designed water-supply and sanitation systems, laid out railroad and highway networks, and planned cities. England and Scotland were the birthplace of mechanical engineering, as a derivation of the inventions of the Scottish engineer James Watt and the textile machinists of the Industrial Revolution. The development of the British machine-tool industry gave tremendous impetus to the study of mechanical engineering both in Britain and abroad.

The growth of knowledge of electricity—from Alessandro Volta’s original electric cell of 1800 through the experiments of Michael Faraday and others, culminating in 1872 in the Gramme dynamo and electric motor (named after the Belgian Z.T. Gramme)—led to the development of electrical and electronics engineering. The electronics aspect became prominent through the work of such scientists as James Clerk Maxwell of Britain and Heinrich Hertz of Germany in the late 19th century. Major advances came with the development of the vacuum tube by Lee De Forest of the United States in the early 20th century and the invention of the transistor in the mid-20th century. In the late 20th century electrical and electronics engineers outnumbered all others in the world.

Chemical engineering grew out of the 19th-century proliferation of industrial processes involving chemical reactions in metallurgy, food, textiles, and many other areas. By 1880 the use of chemicals in manufacturing had created an industry whose function was the mass production of chemicals. The design and operation of the plants of this industry became a function of the chemical engineer.

Engineering Functions

Problem solving is common to all engineering work. The problem may involve quantitative or qualitative factors; it may be physical or economic; it may require abstract mathematics or common sense. Of great importance is the process of creative synthesis or design, putting ideas together to create a new and optimum solution.

Although engineering problems vary in scope and complexity, the same general approach is applicable. First comes an analysis of the situation and a preliminary decision on a plan of attack. In line with this plan, the problem is reduced to a more categorical question that can be clearly stated. The stated question is then answered by deductive reasoning from known principles or by creative synthesis, as in a new design. The answer or design is always checked for accuracy and adequacy. Finally, the results for the simplified problem are interpreted in terms of the original problem and reported in an appropriate form.

In order of decreasing emphasis on science, the major functions of all engineering branches are the following:

• Research. Using mathematical and scientific concepts, experimental techniques, and inductive reasoning, the research engineer seeks new principles and processes.
• Development. Development engineers apply the results of research to useful purposes. Creative application of new knowledge may result in a working model of a new electrical circuit, a chemical process, or an industrial machine.
• Design. In designing a structure or a product, the engineer selects methods, specifies materials, and determines shapes to satisfy technical requirements and to meet performance specifications.
• Construction. The construction engineer is responsible for preparing the site, determining procedures that will economically and safely yield the desired quality, directing the placement of materials, and organizing the personnel and equipment.
• Production. Plant layout and equipment selection are the responsibility of the production engineer, who chooses processes and tools, integrates the flow of materials and components, and provides for testing and inspection.
• Operation. The operating engineer controls machines, plants, and organizations providing power, transportation, and communication; determines procedures; and supervises personnel to obtain reliable and economic operation of complex equipment.
• Management and other functions. In some countries and industries, engineers analyze customers’ requirements, recommend units to satisfy needs economically, and resolve related problems.
• Biography of Dr.A.PJ. Abdul Kalam
  The complete name of Dr. A.P.J. Abdul Kalam is Avul Pakir Jainulabudeen Abdul Kalam. He was born on 15 October 1931 t o Jainulabudeen, a Tamil Muslim boat owner and Ashiamma, a housewife, at Rameshwaram, Tamil Nadu. His family was poor and he had to do assorted jobs to supplement family's income. He completed his  schooling from  the  Schwartz Matriculation School at Ramanathapuram. He then went on  to attend the Saint Joseph's College at Tiruchirappalli. He completed his graduation in Physics in 1954 and then moved on to Madras to study aerospace engineering.After graduating from Madras Institute of Technology (MIT-Chennai) in 1960, Kalam joined Aeronautical Development Establishment of Defence Research and Development Organisation (DRDO) as a scientist. In1969, Kalam was transferred to the Indian Space Research Organisation (ISRO) where he was the project director of lndia's first indigenous Satellite Launch Vehicle (SLV-III) which successfully deployed the Rohini satellite in near earth's orbit in July 1980. Joining ISRO was one of Kalam's biggest achievements in life. His research and educational leadership brought him great laurels and prestige  in  the 1980s, which prompted the government to initiate  an  advanced  missile programme under his directorship. Kalam was the Chief Scientific Adviser to the Prime Minister, and the Secretary of Defence Research and Development Organisation from July 1992 to December 1999. Kalam played a major part in developing many missiles under the mission including Agni. Kalam served as the 11th President of India from 25 July 2002 to 25 July 2007. Kalam was the third President of India to have been honoured with a Bharat Ratna, India's highest civilian honour, before becoming the President. During his term as President, he was affectionately known as the People's President.
