Historically, this area of Lochaber was strongly Clan Cameron country, and there were a number of mainly Cameron settlements in the area ( such as Blarmacfoldach ).

Historically they were sometimes called Feynman-Dyson diagrams or Dyson graphs, because when they were introduced the path integral was unfamiliar, and Freeman Dyson's derivation from old-fashioned perturbation theory was easier to follow for physicists trained in earlier methods.

Historically the first decade of semiconductor electronics were entirely based on germanium, although its production for such use today is a small fraction ( 2 %) of that of ultra-high purity silicon, which has largely replaced it.

Historically, it was of particular relevance to sailing warships which used them to outmaneuver opponents when the wind had dropped but might be used by any vessel in confined, shoal water to place it in a more desirable position, provided she had enough manpower.

Historically, a great number of coinage metals ( including alloys ) and other materials ( e. g. Porcelain ) have been used practically, artistically, and experimentally in the production of coins for circulation, collection, and metal investment, where bullion coins often serve as more convenient stores of assured metal quantity and purity than other bullion.

* Historically, valve amplifiers often used a class-A power amplifier simply because valves are large and expensive ; many class-A designs use only a single device.
