Technology edit

Technology (Gr. τεχνολογια < τεχνη "craftsmanship" + λογος "word, reckoning" + the suffix ια) has more than one definition. One of the definitions is:"the development and application of tools, machines, materials and processes that help to solve human problems." As a human activity, technology predates both science and engineering. It embodies the human knowledge of solving real problems in the design of standard tools, machines, materials or the process. Technology can also be used not only for machines, but for biological purposes such as stem cell researching.

In export situations, technology is often defined in terms of information. For example the UK DTI define it as: "For the purposes of export control, “technology” is defined as specific information necessary for the “development”, “production” or “use” of “goods”, ... this information may take the form of blueprints, plans, diagrams, models, formulae, tables, engineering designs and specifications, or manuals and instructions, either written or recorded on other media or devices such as disks, tapes or read-only memories. The EC regulation also refers to information such as skills, training, working knowledge or consulting services."

Soldering is a process of joining metal parts using a filler metal of low melting point (solder). Heat is applied to the metal parts, and the soft filler metal is pressed against the joint, melts, and is drawn into the joint by capillary action with the help of the appropriate flux material (which helps reduce oxidation of the metal parts and increases the strength of the bond). After the metal cools, the resulting joints are not as strong as the base metal, but have adequate strength, electrical conductivity, and water-tightness for many uses. Soldering is an ancient technique that has been used practically as long as humans have been making articles out of metal..........
