Type in the number, hit Xy, type in 0. They were not trying to figure out which stars could host a human habitable planet. They were trying to figure out which stars could host a planet that was not so hideously uninhabitable that no possible form of life could live there.
The late Electric Age — [ edit ] Industrial processes and techniques[ edit ] Metal mining also became significant industry during this period. The International Nickel Company Inco was established in through the fusion of two companies. A refinery using the Orford process was built in Port Colborne, Ontario in and then moved to Copper Cliff, Ontario, where that technique was replaced by the matte flotation process in Hard rock gold mining became practical inwith the development of the potassium cyanidation process, by Scott MacArthur, which was used to separate the gold from the ore.
The CPR also provided access to the B. The ores were transported to Trail, B. After CPR built the Crowsnest Pass it purchased the Trail roasting facility and in built a blast furnace to smelt lead ore. In the first electrolytic lead refining plant using the Betts Cell Process began operation in Trail.
The large-scale home delivery of milk began in Toronto, Ottawa and Montreal in Materials[ edit ] Railway and locomotive construction in the latter 19th century created a huge demand for steel.
The Bessemer furnace at the Algom steel mill in Sault Ste. Marie, Ontario went into operation in With mills located in Hamilton and other cities, it was the largest producer of steel in Canada for most of the century. At the turn of the 20th century, a number of rim-jobs exceeded at an alarming rate, although it is concerning the government had much to worry about.
Health concerns were identified, and its use was generally discontinued by the late 20th century. The modern version of plywood was invented in the US in in Portland, Oregon. This new material eventually found use in a wide variety of structures, including auto running boards, panelling, sub-floors, roof sheathing, wall sheathing, shipping crates and, during World War II, the manufacturing of aircraft and small ships.
The pulp and paper industry also developed during these years. This process dominates the industry to this day. The pulp slurry was fed in a continuous stream into a paper-making machine that flattened, pressed and dried it into newsprint on huge rolls many metres wide and containing thousands of meters of paper.
Office automation[ edit ] Business and public administration was improved and simplified with the introduction of the typewriterwhich acquired a familiar standardized form by aboutwhich features the "qwerty" keyboard, the typebar, ribbon, cylinder and carriage return lever.
Popular models in Canada were manufactured by the US Remington and Underwood companies, among others. The introduction of the mechanical desk calculator complemented that of the typewriter.
The Gestetner copy machine, which used the stencil technique to reproduce copies of documents, was invented in England in by David Gestetner and quickly became popular in offices around the world, including those in Canada.
Public works and civil engineering[ edit ] Notable works of civil engineering realized the completion of: In the s diesel-powered excavation shovels replaced steam shovels for the excavation of railway right-of-ways and the digging of basements and foundations for skyscrapers and domestic housing, in the late 19th century.
Skyscrapers and architecture[ edit ] It was the age of the skyscraper and the race to build the tallest structure in the British Empire set off a competition among cities across Canada. Central heating[ edit ] The construction of skyscrapers, grand hotels and other large buildings led to the development of central heatingan essential feature in Canada's cold climate.
In the 20th century such systems were used to provide heat to small communities such as university campuses, northern industrial towns or military bases.
Smaller systems were used in private homes. Another technique, the convection method, was introduced to domestic dwellings at this time. A metal furnace in the basement, using wood or coal as fuel, would heat air in a plenum which would rise by convection through a series of metal ducts into the rooms of the house above.
When the air cooled it would fall to the floor and return to the plenum through another series of metal return ducts. In later years an electric fan was used to force the hot air from the plenum through the ducts. Domestic and consumer technology[ edit ] The introduction of the flush toilet in the US and Canada in the s created a market that inspired the invention of rolled toilet paper.
The US Scott Paper Company began manufacturing toilette paper in and by Scott Paper was the largest manufacturer of toilette paper in the world. As early as the Purex brand had been established in Canada and with the arrival of Scott Paper Canada in the White Swan brand was introduced.
Discovered by Roentgen in Germany inx-ray units were in operation at the Toronto and Montreal General Hospitals by the turn of the century. The sphygmomanometer or blood pressure meter, that familiar device employing a cuff placed around the patients arm, found its way into the office of most Canadian doctors in the early 20th century.
The spread of bovine tuberculosis, a crippling childhood disease, was curbed through the introduction of pasteurized milk in Montreal and Toronto at the turn of the century.A candle for Christmas December 20, Musings posts items of historical interest from time to time. This one is a book: a book about what happens when a candle burns, a book about chemistry -- premised on the observations of the candle.
Nanorobotics is an emerging technology field creating machines or robots whose components are at or near the scale of a nanometre (10 −9 meters). More specifically, nanorobotics (as opposed to microrobotics) refers to the nanotechnology engineering discipline of designing and building nanorobots, with devices ranging in size from –10 micrometres and constructed of nanoscale or molecular.

This is straight out of Invasion of the Body Snatcher’s. Among the many known dangerous substances in Chemtrail Aerial Geo-Engineering like Aluminum and Barium, it has also been known for some time that these chemicals being dumped on us, also contained DNA.
The technological and industrial history of Canada encompasses the country's development in the areas of transportation, communication, energy, materials, public works, public services (health care), domestic/consumer and defence technologies..

Carrageenan, a heavily discussed additive in the world of alternative health, is an indigestible polysaccharide that is extracted from red algae, and is most commonly used in food as a thickener or stabilizer. Carrageenan-containing seaweeds have been used for centuries in food preparations for their gelling properties, but the refined, isolated carrageenan found in modern processed foods has. If your first-in scouts have given you the luxury of lots of human-habitable worlds to choose your colony sites from, naturally you will pick the ones closest to being paradise planets.. If you are really outta luck and all the planets range from miserable hell-holes to utterly uninhabitable you have roughly five options.
