The steam engine, the major driver in the Industrial Revolution, underscores the importance of engineering in modern history. This beam engine is on display in the Technical University of Madrid.

Engineering is the use of scientific principles to design and build machines, structures, and other items, including bridges, tunnels, roads, vehicles, and buildings. The discipline of engineering encompasses a broad range of more specialized fields of engineering, each with a more specific emphasis on particular areas of applied mathematics, applied science, and types of application. See glossary of engineering.

The term engineering is derived from the Latin ingenium, meaning "cleverness" and ingeniare, meaning "to contrive, devise". (Full article...)

Engineers, as practitioners of engineering, are professionals who invent, design, analyze, build and test machines, complex systems, structures, gadgets and materials to fulfill functional objectives and requirements while considering the limitations imposed by practicality, regulation, safety and cost. The word engineer (Latin ingeniator) is derived from the Latin words ingeniare ("to contrive, devise") and ingenium ("cleverness"). The foundational qualifications of an engineer typically include a four-year bachelor's degree in an engineering discipline, or in some jurisdictions, a master's degree in an engineering discipline plus four to six years of peer-reviewed professional practice (culminating in a project report or thesis) and passage of engineering board examinations.

Norman Selfe.jpg
Studio portrait of Selfe

Norman Selfe (9 December 1839 – 15 October 1911) was an Australian engineer, naval architect, inventor, urban planner and outspoken advocate of technical education. After emigrating to Sydney with his family from England as a boy he became an apprentice engineer, following his father's trade. Selfe designed many bridges, docks, boats, and much precision machinery for the city. He also introduced new refrigeration, hydraulic, electrical and transport systems. For these achievements he received international acclaim during his lifetime. Decades before the Sydney Harbour Bridge was built, the city came close to building a Selfe-designed steel cantilever bridge across the harbour after he won the second public competition for a bridge design.

Selfe was honoured during his life by the name of the Sydney suburb of Normanhurst, where his grand house Gilligaloola is a local landmark. He was energetically involved in organisations such as the Sydney Mechanics' School of Arts and the Australian Historical Society. As president of the Board of Technical Education, he fought consistently for the establishment of an independent system of technical education to serve the needs of a rapidly industrialising society. He was acknowledged upon his death as one of the best-known people in, and greatest individual influences upon, the city of Sydney. (Full article...)

The SCARA acronym stands for Selective Compliance Assembly Robot Arm or Selective Compliance Articulated Robot Arm.

In 1981, Sankyo Seiki, Pentel and NEC presented a completely new concept for assembly robots. The robot was developed under the guidance of Hiroshi Makino, a professor at the University of Yamanashi. The robot was called Selective Compliance Assembly Robot Arm, SCARA. Its arm was rigid in the Z-axis and pliable in the XY-axes, which allowed it to adapt to holes in the XY-axes.

By virtue of the SCARA's parallel-axis joint layout, the arm is slightly compliant in the X-Y direction but rigid in the 'Z' direction, hence the term: Selective Compliant. This is advantageous for many types of assembly operations, i.e., inserting a round pin in a round hole without binding.
