Electronics
Electronics is the discipline dealing with the development and application of devices and systems involving the flow of electrons in a vacuum, in gaseous media, and in semiconductors. Electronics deals with electrical circuits that involve active electrical components such as vacuum tubes, transistors, diodes, integrated circuits, optoelectronics, and sensors, associated passive electrical components, and interconnection technologies. Commonly, electronic devices contain circuitry consisting primarily or exclusively of active semiconductors supplemented with passive elements; such a circuit is described as an electronic circuit.
Manufacturing
Manufacturing is the production of merchandise for use or sale using labour and machines, tools, chemical and biological processing, or formulation. The term may refer to a range of human activity, from handicraft to high tech, but is most commonly applied to industrial production, in which raw materials are transformed into finished goods on a large scale. Such finished goods may be sold to other manufacturers for the production of other, more complex products, such as aircraft, household appliances, furniture, sports equipment or automobiles, or sold to wholesalers, who in turn sell them to retailers, who then sell them to end users and consumers.
Photonics
Photonics is the physical science of light (photon) generation, detection, and manipulation through emission, transmission, modulation, signal processing, switching, amplification, and detection/sensing. Though covering all light's technical applications over the whole spectrum, most photonic applications are in the range of visible and near-infrared light. The term photonics developed as an outgrowth of the first practical semiconductor light emitters invented in the early 1960s and optical fibers developed in the 1970s.
Manufacturing
In short, intelligence, considered in what seems to be its original feature, is the faculty of manufacturing artificial objects, especially tools to make tools, and of indefinitely urging the manufacture.
Henri Bergson, Creative Evolution (1907), Chapter II
Manufacturing
Mechanical engineering is applicable rather to works connected with private enterprise, such as the designing and construction of steam machinery for the purposes of navigation and transportation, the adaptation of such machinery to mills and factories, the construction of water-wheels, the fabrication of materials, iron, steel, and brass, for the purposes of the engineer, the architect, and manufacturer ; and the manufacture of implements and machinery for agriculture, for mining, and for domestic purposes.

Manufacturing
A wide market awaited the manufacturer of food products who would set purity and quality above everything else in their preparation.
