Mass production
–
Mass production, flow production or continuous production is the production of large amounts of standardized products, including and especially on assembly lines. Together with job production and batch production, it is one of the three main production methods, the term mass production was popularized by a 1926 article in the Encyclopedia Britannica supplement that was written based on correspondence with Ford Motor Company. The New York Times used the term in the title of an article that appeared before publication of the Britannica article, the concepts of mass production are applied to various kinds of products, from fluids and particulates handled in bulk to discrete solid parts to assemblies of such parts. Mass production is a field, but it can generally be contrasted with craft production or distributed manufacturing. Mass production of fluid matter typically involves pipes with centrifugal pumps or screw conveyors to transfer raw materials or partially complete products between vessels, materials on pallets are handled with forklifts. Also used for handling heavy items like reels of paper, steel or machinery are electric overhead cranes, sometimes called bridge cranes because they span large factory bays. Mass production is intensive and energy intensive, as it uses a high proportion of machinery. It is also usually automated while total expenditure per unit of product is decreased, however, the machinery that is needed to set up a mass production line is so expensive that there must be some assurance that the product is to be successful to attain profits. One of the descriptions of mass production is that the skill is built into the tool, for example, in the 19th or early 20th century, this could be expressed as the craftsmanship is in the workbench itself. Later, once computerized control came about, jigs were obviated and this is the specialized capital required for mass production, each workbench and set of tools is different. Crossbows made with bronze parts were produced in China during the Warring States period, the Qin Emperor unified China at least in part by equipping large armies with these weapons, which were equipped with a sophisticated trigger mechanism made of interchangeable parts. Ships of war were produced on a scale at a moderate cost by the Carthaginians in their excellent harbors. The Venetians themselves also produced ships using prefabricated parts and assembly lines many centuries later, the Venetian Arsenal apparently produced nearly one ship every day, in what was effectively the worlds first factory which, at its height, employed 16,000 people. Mass production in the industry has been commonplace since the Gutenberg Bible was published using a printing press in the mid-15th century. In the Industrial Revolution simple mass production techniques were used at the Portsmouth Block Mills in England to make ships pulley blocks for the Royal Navy in the Napoleonic Wars. It was achieved in 1803 by Marc Isambard Brunel in cooperation with Henry Maudslay under the management of Sir Samuel Bentham, the Navy was in a state of expansion that required 100,000 pulley blocks to be manufactured a year. Bentham had already achieved remarkable efficiency at the docks by introducing power-driven machinery, by 1805, the dockyard had been fully updated with the revolutionary, purpose-built machinery at a time when products were still built individually with different components. A total of 45 machines were required to perform 22 processes on the blocks, the machines were almost entirely made of metal thus improving their accuracy and durability

Lean manufacturing
–
Lean manufacturing or lean production, often simply lean, is a systematic method for the elimination of waste within a manufacturing system. Lean also takes into account waste created through overburden and waste created through unevenness in work loads, working from the perspective of the client who consumes a product or service, value is any action or process that a customer would be willing to pay for. Lean manufacturing makes obvious what adds value, by reducing everything else and this management philosophy is derived mostly from the Toyota Production System and identified as lean only in the 1990s. TPS is renowned for its focus on reduction of the original Toyota seven wastes to improve overall customer value, the steady growth of Toyota, from a small company to the worlds largest automaker, has focused attention on how it has achieved this success. Lean principles are derived from the Japanese manufacturing industry, the term was first coined by John Krafcik in his 1988 article, Triumph of the Lean Production System, based on his masters thesis at the MIT Sloan School of Management. Krafcik had been a quality engineer in the Toyota-GM NUMMI joint venture in California before joining MIT for MBA studies, a complete historical account of the IMVP and how the term lean was coined is given by Holweg. For many, lean is the set of tools that assist in the identification, as waste is eliminated quality improves while production time and cost are reduced. Techniques to improve flow include production leveling, pull production and the Heijunka box, the difference between these two approaches is not the goal itself, but rather the prime approach to achieving it. The implementation of smooth flow exposes quality problems that already existed, the advantage claimed for this approach is that it naturally takes a system-wide perspective, whereas a waste focus sometimes wrongly assumes this perspective. Both lean and TPS can be seen as a connected set of potentially competing principles whose goal is cost reduction by the elimination of waste. Thus what one sees today is the result of a need driven learning to improve where each step has built on previous ideas, from this perspective, the tools are workarounds adapted to different situations, which explains any apparent incoherence of the principles above. Also known as the mass production, the TPS has two pillar concepts, Just-in-time or flow, and autonomation. Adherents of the Toyota approach would say that the smooth flowing delivery of value achieves all the improvements as side-effects. The other of the two TPS pillars is the human aspect of autonomation, whereby automation is achieved with a human touch. In this instance, the human touch means to automate so that the machines/systems are designed to aid humans in focusing on what the humans do best. These concepts of flexibility and change are principally required to allow production leveling, using tools like SMED, the flexibility and ability to change are within bounds and not open-ended, and therefore often not expensive capability requirements. More importantly, all of concepts have to be understood, appreciated. The cultural and managerial aspects of lean are possibly more important than the tools or methodologies of production itself

Programmable logic controller
–
They were first developed in the automobile industry to provide flexible, ruggedised and easily programmable controllers to replace hard-wired relays and timers. Since then they have widely adopted as high-reliability automation controllers suitable for harsh environments. A PLC is an example of a hard real-time system since output results must be produced in response to input conditions within a limited time, otherwise unintended operation will result. They can be designed for multiple arrangements of digital and analog inputs and outputs, extended temperature ranges, immunity to electrical noise, programs to control machine operation are typically stored in battery-backed-up or non-volatile memory. It was from the industry in the USA that the PLC was born. Before the PLC, control, sequencing, and safety interlock logic for manufacturing automobiles was mainly composed of relays, cam timers, drum sequencers, when digital computers became available, being general-purpose programmable devices, they were soon applied to control sequential and combinatorial logic in industrial processes. However these early computers required specialist programmers and stringent operating environmental control for temperature, cleanliness, to meet these challenges the PLC was developed with several key attributes. In 1968 GM Hydra-Matic issued a request for proposals for a replacement for hard-wired relay systems based on a white paper written by engineer Edward R. Clark. The winning proposal came from Bedford Associates of Bedford, Massachusetts, the first PLC, designated the 084 because it was Bedford Associates eighty-fourth project, was the result. Bedford Associates started a new company dedicated to developing, manufacturing, selling, and servicing this new product, Modicon, one of the people who worked on that project was Dick Morley, who is considered to be the father of the PLC. The Modicon brand was sold in 1977 to Gould Electronics, later acquired by German Company AEG, and then by French Schneider Electric, one of the very first 084 models built is now on display at Schneider Electrics facility in North Andover, Massachusetts. It was presented to Modicon by GM, when the unit was retired after twenty years of uninterrupted service. Modicon used the 84 moniker at the end of its product range until the 984 made its appearance, the automotive industry is still one of the largest users of PLCs. Early PLCs were designed to replace relay logic systems and these PLCs were programmed in ladder logic, which strongly resembles a schematic diagram of relay logic. This program notation was chosen to reduce training demands for the existing technicians, other early PLCs used a form of instruction list programming, based on a stack-based logic solver. Modern PLCs can be programmed in a variety of ways, from the ladder logic to programming languages such as specially adapted dialects of BASIC. Another method is state logic, a very high-level programming language designed to program PLCs based on state transition diagrams. As programming terminals evolved, it more common for ladder logic to be used, for the aforementioned reasons

Tool
–
A tool is any physical item that can be used to achieve a goal, especially if the item is not consumed in the process. Tool use by humans dates back millions of years, and other animals are known to employ simple tools. Tools that are used in fields or activities may have different designations such as instrument, utensil, implement, machine, device. The set of tools needed to achieve a goal is equipment, the knowledge of constructing, obtaining and using tools is technology. Anthropologists believe that the use of tools was an important step in the evolution of mankind, because tools are used extensively by both humans and wild chimpanzees, it is widely assumed that the first routine use of tools took place prior to the divergence between the two species. These early tools, however, were made of perishable materials such as sticks. Stone artifacts only date back to about 2.5 million years ago, however, a 2010 study suggests the hominin species Australopithecus afarensis ate meat by carving animal carcasses with stone implements. This finding pushes back the earliest known use of tools among hominins to about 3.4 million years ago. Finds of actual tools date back at least 2.6 million years in Ethiopia, one of the earliest distinguishable stone tool forms is the hand axe. Up until recently, weapons found in digs were the tools of “early man” that were studied. Now, more tools are recognized as culturally and historically relevant, as well as hunting, other activities required tools such as preparing food, “…nutting, leatherworking, grain harvesting and woodworking…” Included in this group are “flake stone tools. “Man the hunter” as the catalyst for Hominin change has been questioned, based on marks on the bones at archaeological sites, it is now more evident that pre-humans were scavenging off of other predators carcasses rather than killing their own food. Mechanical devices experienced an expansion in their use in Ancient Greece and Ancient Rome with the systematic employment of new energy sources. Their use expanded through the Dark Ages with the addition of windmills, machine tools occasioned a surge in producing new tools in the industrial revolution. Advocates of nanotechnology expect a similar surge as tools become microscopic in size, one can classify tools according to their basic functions, Cutting and edge tools, such as the knife, scythe or sickle, are wedge-shaped implements that produce a shearing force along a narrow face. Ideally, the edge of the needs to be harder than the material being cut or else the blade will become dulled with repeated use. But even resilient tools will require periodic sharpening, which is the process of removing deformation wear from the edge, other examples of cutting tools include gouges and drill bits. Moving tools move large and tiny items, many are levers which give the user a mechanical advantage

Biology
–
Biology is a natural science concerned with the study of life and living organisms, including their structure, function, growth, evolution, distribution, identification and taxonomy. Modern biology is a vast and eclectic field, composed of branches and subdisciplines. However, despite the broad scope of biology, there are certain unifying concepts within it that consolidate it into single, coherent field. In general, biology recognizes the cell as the unit of life, genes as the basic unit of heredity. It is also understood today that all organisms survive by consuming and transforming energy and by regulating their internal environment to maintain a stable, the term biology is derived from the Greek word βίος, bios, life and the suffix -λογία, -logia, study of. The Latin-language form of the term first appeared in 1736 when Swedish scientist Carl Linnaeus used biologi in his Bibliotheca botanica, the first German use, Biologie, was in a 1771 translation of Linnaeus work. In 1797, Theodor Georg August Roose used the term in the preface of a book, karl Friedrich Burdach used the term in 1800 in a more restricted sense of the study of human beings from a morphological, physiological and psychological perspective. The science that concerns itself with these objects we will indicate by the biology or the doctrine of life. Although modern biology is a recent development, sciences related to. Natural philosophy was studied as early as the ancient civilizations of Mesopotamia, Egypt, the Indian subcontinent, however, the origins of modern biology and its approach to the study of nature are most often traced back to ancient Greece. While the formal study of medicine back to Hippocrates, it was Aristotle who contributed most extensively to the development of biology. Especially important are his History of Animals and other works where he showed naturalist leanings, and later more empirical works that focused on biological causation and the diversity of life. Aristotles successor at the Lyceum, Theophrastus, wrote a series of books on botany that survived as the most important contribution of antiquity to the plant sciences, even into the Middle Ages. Scholars of the medieval Islamic world who wrote on biology included al-Jahiz, Al-Dīnawarī, who wrote on botany, biology began to quickly develop and grow with Anton van Leeuwenhoeks dramatic improvement of the microscope. It was then that scholars discovered spermatozoa, bacteria, infusoria, investigations by Jan Swammerdam led to new interest in entomology and helped to develop the basic techniques of microscopic dissection and staining. Advances in microscopy also had a impact on biological thinking. In the early 19th century, a number of biologists pointed to the importance of the cell. Thanks to the work of Robert Remak and Rudolf Virchow, however, meanwhile, taxonomy and classification became the focus of natural historians

Handicraft
–
One of the worlds oldest handicraft is Dhokra, this is a sort of metal casting has been used in India for over 4,000 years and is still used. Collective terms for handicrafts include artisanry, handicrafting, crafting, many handicrafters use natural, even entirely indigenous, materials while others may prefer modern, non-traditional materials, and even upcycle industrial materials. The individual artisanship of an item is the paramount criterion. Most crafts require the development of skill and the application of patience, like folk art, handicraft output often has cultural and/or religious significance, and increasingly may have a political message as well, as in craftivism. The Arts and Crafts movement originated as a late 19th-century design reform and social movement principally in Europe, North America and Australia and this was held up in contrast to what was perceived to be the alienating effects of industrial labor. These activities were called crafts because originally many of them were professions under the guild system, adolescents were apprenticed to a master craftsman, and refined their skills over a period of years in exchange for low wages. Simple arts and crafts projects are an elementary and middle school activity in both mainstream and alternative education systems around the world. e. The use of traditional handicrafting techniques by professional fine artists, many community centers and schools run evening or day classes and workshops, for adults and children, offering to teach basic craft skills in a short period of time. If sold, they are sold in Direct sales, Gift shops, Public markets, in developing countries, handicrafts are sold to locals and as Souvenirs to tourists. Sellers tend to speak at least a few words of common tourist languages

Aircraft
–
An aircraft is a machine that is able to fly by gaining support from the air. It counters the force of gravity by using either static lift or by using the lift of an airfoil. The human activity that surrounds aircraft is called aviation, crewed aircraft are flown by an onboard pilot, but unmanned aerial vehicles may be remotely controlled or self-controlled by onboard computers. Aircraft may be classified by different criteria, such as type, aircraft propulsion, usage. Each of the two World Wars led to technical advances. Consequently, the history of aircraft can be divided into five eras, Pioneers of flight, first World War,1914 to 1918. Aviation between the World Wars,1918 to 1939, Second World War,1939 to 1945. Postwar era, also called the jet age,1945 to the present day, aerostats use buoyancy to float in the air in much the same way that ships float on the water. They are characterized by one or more large gasbags or canopies, filled with a relatively low-density gas such as helium, hydrogen, or hot air, which is less dense than the surrounding air. When the weight of this is added to the weight of the aircraft structure, a balloon was originally any aerostat, while the term airship was used for large, powered aircraft designs – usually fixed-wing. In 1919 Frederick Handley Page was reported as referring to ships of the air, in the 1930s, large intercontinental flying boats were also sometimes referred to as ships of the air or flying-ships. – though none had yet been built, the advent of powered balloons, called dirigible balloons, and later of rigid hulls allowing a great increase in size, began to change the way these words were used. Huge powered aerostats, characterized by an outer framework and separate aerodynamic skin surrounding the gas bags, were produced. There were still no fixed-wing aircraft or non-rigid balloons large enough to be called airships, then several accidents, such as the Hindenburg disaster in 1937, led to the demise of these airships. Nowadays a balloon is an aerostat and an airship is a powered one. A powered, steerable aerostat is called a dirigible, sometimes this term is applied only to non-rigid balloons, and sometimes dirigible balloon is regarded as the definition of an airship. Non-rigid dirigibles are characterized by a moderately aerodynamic gasbag with stabilizing fins at the back and these soon became known as blimps. During the Second World War, this shape was adopted for tethered balloons, in windy weather

Furniture
–
Furniture refers to movable objects intended to support various human activities such as seating, eating, and sleeping. Furniture is also used to hold objects at a convenient height for work, Furniture can be a product of design and is considered a form of decorative art. In addition to furnitures functional role, it can serve a symbolic or religious purpose and it can be made from many materials, including metal, plastic, and wood. Furniture can be using a variety of woodworking joints which often reflect the local culture. People have been using natural objects, such as stumps, rocks and moss. Archaeological research shows that from around 30,000 years ago, people began constructing and carving their own furniture, using wood, stone, early furniture from this period is known from artwork such as a Venus figurine found in Russia, depicting the goddess on a throne. The first surviving extant furniture is in the homes of Skara Brae in Scotland, complex construction techniques such as joinery began in the early dynastic period of ancient Egypt. This era saw constructed wooden pieces, including stools and tables, sometimes decorated with valuable metals or ivory. The evolution of furniture design continued in ancient Greece and ancient Rome, with thrones being commonplace as well as the klinai, multipurpose couches used for relaxing, eating, the furniture of the Middle Ages was usually heavy, oak, and ornamented. Furniture design expanded during the Italian Renaissance of the fourteenth and fifteenth century, the seventeenth century, in both Southern and Northern Europe, was characterized by opulent, often gilded Baroque designs. The nineteenth century is defined by revival styles. The first three-quarters of the century are often seen as the march towards Modernism. One unique outgrowth of post-modern furniture design is a return to natural shapes and textures, the English word furniture is derived from the French word fourniture, the noun form of fournir, which means to supply or provide. Thus fourniture in French means supplies or provisions, the practice of using natural objects as rudimentary pieces of furniture likely dates to the beginning of human civilisation. Early humans are likely to have used tree stumps as seats, rocks as rudimentary tables, during the late palaeolithic or early neolithic period, from around 30,000 years ago, people began constructing and carving their own furniture, using wood, stone, and animal bones. The earliest evidence for the existence of constructed furniture is a Venus figurine found at the Gagarino site in Russia, a similar statue of a Mother Goddess was found in Catal Huyuk in Turkey, dating to between 6000 and 5500 BC. The inclusion of such a seat in the figurines implies that these were already common artefacts of that age, a range of unique stone furniture has been excavated in Skara Brae, a Neolithic village in Orkney, Scotland. Each house shows a degree of sophistication and was equipped with an extensive assortment of stone furniture, ranging from cupboards, dressers and beds to shelves, stone seats

Car
–
A car is a wheeled, self-powered motor vehicle used for transportation and a product of the automotive industry. The year 1886 is regarded as the year of the modern car. In that year, German inventor Karl Benz built the Benz Patent-Motorwagen, cars did not become widely available until the early 20th century. One of the first cars that was accessible to the masses was the 1908 Model T, an American car manufactured by the Ford Motor Company. Cars were rapidly adopted in the United States of America, where they replaced animal-drawn carriages and carts, cars are equipped with controls used for driving, parking, passenger comfort and safety, and controlling a variety of lights. Over the decades, additional features and controls have been added to vehicles, examples include rear reversing cameras, air conditioning, navigation systems, and in car entertainment. Most cars in use in the 2010s are propelled by a combustion engine. Both fuels cause air pollution and are blamed for contributing to climate change. Vehicles using alternative fuels such as ethanol flexible-fuel vehicles and natural gas vehicles are also gaining popularity in some countries, electric cars, which were invented early in the history of the car, began to become commercially available in 2008. There are costs and benefits to car use, the costs of car usage include the cost of, acquiring the vehicle, interest payments, repairs and auto maintenance, fuel, depreciation, driving time, parking fees, taxes, and insurance. The costs to society of car use include, maintaining roads, land use, road congestion, air pollution, public health, health care, road traffic accidents are the largest cause of injury-related deaths worldwide. The benefits may include transportation, mobility, independence. The ability for humans to move flexibly from place to place has far-reaching implications for the nature of societies and it was estimated in 2010 that the number of cars had risen to over 1 billion vehicles, up from the 500 million of 1986. The numbers are increasing rapidly, especially in China, India, the word car is believed to originate from the Latin word carrus or carrum, or the Middle English word carre. In turn, these originated from the Gaulish word karros, the Gaulish language was a branch of the Brythoic language which also used the word Karr, the Brythonig language evolved into Welsh where Car llusg and car rhyfel still survive. It originally referred to any wheeled vehicle, such as a cart, carriage. Motor car is attested from 1895, and is the formal name for cars in British English. Autocar is a variant that is attested from 1895

Retail
–
Retail markets and shops have a very ancient history, dating back to antiquity. Retailing involves the process of selling goods or services to customers through multiple channels of distribution to earn a profit. Retailers satisfy demand is identified through a supply chain, Once the strategic retail plan is in place, retailers devise the retail mix which includes product, price, place, promotion, personnel and presentation. In the digital age, a number of retailers are seeking to reach broader markets by selling through multiple channels. Digital technologies are changing the way that consumers pay for goods. Retailing support services may include the provision of credit, delivery services. Shopping generally refers to the act of buying products, sometimes this is done to obtain final goods, including necessities such as food and clothing, sometimes it takes place as a recreational activity. Recreational shopping often involves window shopping and browsing, it not always result in a purchase. Retail shops occur in a range of types and in many different contexts - from strip shopping centres in residential streets through to large. Shopping streets may restrict traffic to pedestrians only, forms of non-shop retailing include online retailing and mail order. Retail comes from the Old French word tailler, which means to cut off, clip, pare and it was first recorded as a noun with the meaning of a sale in small quantities in 1433. Like in French, the retail in both Dutch and German also refers to the sale of small quantities of items. Also see History of merchants, History of the market place, open air, public markets were known in ancient Babylonia and Assyria. These markets typically occupied a place in the towns centre, surrounding the market, skilled artisans, such as metal-workers and leather workers, occupied premises in alley ways that led to the open market-place. These artisans may have sold wares directly from their premises, in ancient Greece markets operated within the agora, and in ancient Rome the forum. In antiquity, exchange involved direct selling, merchants or peddlers, the Phoenicians, noted for their seafaring skills, plied their ships across the Mediterranean, becoming a major trading power by 9th century BCE. The Phoenicians imported and exported wood, textiles, glass and produce such as wine, oil, dried fruit, the Phoenicians extensive trade networks necessitated considerable book-keeping and correspondence. In around 1500 BCE, the Phoenicians developed an alphabet which was much easier to learn that the complex scripts used in ancient Egypt

Manufacturing engineering
–
The manufacturing engineers primary focus is to turn raw materials into a new or updated product in the most economic, efficient, and effective way possible. It is a broad area which includes the design and development of products. Manufacturing engineering is considered to be a subdiscipline of industrial engineering and has very strong overlaps with mechanical engineering. Manufacturing engineers success or failure directly impacts the advancement of technology and this field of manufacturing engineering emerged from tool and die discipline in the early 20th century. It expanded greatly from the 1960s when industrialized countries introduced factories with,1, numerical control machine tools and automated systems of production. Advanced statistical methods of quality control, These factories were pioneered by the American electrical engineer William Edwards Deming, the same methods of quality control later turned Japanese factories into world leaders in cost-effectiveness and production quality. This cut costs and improved production speed, the history of manufacturing engineering can be traced to factories in the mid 19th century USA and 18th century UK. Founded in 1104 in the Republic of Venice several hundred years before the Industrial Revolution, the Venice Arsenal apparently produced nearly one ship every day and, at its height, employed 16,000 people. Many historians regard Matthew Boultons Soho Manufactory as the first modern factory, similar claims can be made for John Lombes silk mill in Derby, or Richard Arkwrights Cromford Mill. The Cromford Mill was purpose-built to accommodate the equipment it held, one historian, Murno Gladst, contends that the first factory was in Potosí. The Potosi factory took advantage of the abundant silver that was mined nearby, british colonies in the 19th century built factories simply as buildings where a large number of workers gathered to perform hand labor, usually in textile production. This proved more efficient for the administration and distribution of materials to individual workers than earlier methods of manufacturing and this experience formed the basis for the later studies of manufacturing engineering. Between 1820 and 1850, non-mechanized factories supplanted traditional artisan shops as the predominant form of manufacturing institution, henry Ford further revolutionized the factory concept and thus manufacturing engineering in the early 20th century with the innovation of mass production. Highly specialized workers situated alongside a series of rolling ramps would build up a product such as an automobile and this concept dramatically decreased production costs for virtually all manufactured goods and brought about the age of consumerism. Modern manufacturing engineering studies include all intermediate processes required for the production and integration of a products components, some industries, such as semiconductor and steel manufacturers use the term fabrication for these processes. Automation is used in different processes of manufacturing such as machining and welding, automated manufacturing refers to the application of automation to produce goods in a factory. Robotics is the application of mechatronics and automation to create robots and these robots may be of any shape and size, but all are preprogrammed and interact physically with the world. To create a robot, an engineer typically employs kinematics and mechanics, robots are used extensively in manufacturing engineering

Engineering
–
The term Engineering is derived from the Latin ingenium, meaning cleverness and ingeniare, meaning to contrive, devise. Engineering has existed since ancient times as humans devised fundamental inventions such as the wedge, lever, wheel, each of these inventions is essentially consistent with the modern definition of engineering. The term engineering is derived from the engineer, which itself dates back to 1390 when an engineer originally referred to a constructor of military engines. In this context, now obsolete, a referred to a military machine. Notable examples of the obsolete usage which have survived to the present day are military engineering corps, the word engine itself is of even older origin, ultimately deriving from the Latin ingenium, meaning innate quality, especially mental power, hence a clever invention. The earliest civil engineer known by name is Imhotep, as one of the officials of the Pharaoh, Djosèr, he probably designed and supervised the construction of the Pyramid of Djoser at Saqqara in Egypt around 2630–2611 BC. Ancient Greece developed machines in both civilian and military domains, the Antikythera mechanism, the first known mechanical computer, and the mechanical inventions of Archimedes are examples of early mechanical engineering. In the Middle Ages, the trebuchet was developed, the first steam engine was built in 1698 by Thomas Savery. The development of this gave rise to the Industrial Revolution in the coming decades. With the rise of engineering as a profession in the 18th century, similarly, in addition to military and civil engineering, the fields then known as the mechanic arts became incorporated into engineering. The inventions of Thomas Newcomen and the Scottish engineer James Watt gave rise to mechanical engineering. The development of specialized machines and machine tools during the revolution led to the rapid growth of mechanical engineering both in its birthplace Britain and abroad. John Smeaton was the first self-proclaimed civil engineer and is regarded as the father of civil engineering. He was an English civil engineer responsible for the design of bridges, canals, harbours and he was also a capable mechanical engineer and an eminent physicist. Smeaton designed the third Eddystone Lighthouse where he pioneered the use of hydraulic lime and his lighthouse remained in use until 1877 and was dismantled and partially rebuilt at Plymouth Hoe where it is known as Smeatons Tower. The United States census of 1850 listed the occupation of engineer for the first time with a count of 2,000, there were fewer than 50 engineering graduates in the U. S. before 1865. In 1870 there were a dozen U. S. mechanical engineering graduates, in 1890 there were 6,000 engineers in civil, mining, mechanical and electrical. There was no chair of applied mechanism and applied mechanics established at Cambridge until 1875, the theoretical work of James Maxwell and Heinrich Hertz in the late 19th century gave rise to the field of electronics
