    Chemical and Chemical Products Industries

    Chemical manufacturing entails the conversion of one material to another by a chemical reaction on a commercial scale. The starting material (feedstock) can be a natural substance or a relatively pure chemical used as an "intermediate" for subsequent upgrading.

    Chemistry

    Chemistry, the science concerned primarily with the structure and properties of matter and with the transformation of one form of matter into another. Now one of the most theoretically and methodologically sophisticated sciences, chemistry had its beginnings in medieval alchemy. Because chemistry studies matter at a basic level, it is concerned with the physical sciences (e.g., physics), the life sciences (e.g., biochemistry, contemporary medicine) and the earth sciences (e.g., geology, geochemistry). Not only do chemical studies aim to understand natural processes, they also underpin production of many goods essential to daily living, ranging from food and drugs, through substances used in the visual arts, to heat and electricity. Chemical engineers specialize in the transfer of knowledge from the academic sphere to that of industry.

    Chemistry Subdisciplines

    Early chemistry was principally analytical in nature; only as the body of experimental data increased did the present-day specialities evolve. The principal chemical subdisciplines are analytical, inorganic, organic and physical chemistry.

    Tsilhqot'in (Chilcotin)

    The Tsilhqot'in (Chilcotin) are an Indigenous people who live between the Fraser River and the Coast Mountains in west-central British Columbia. Traditionally Dene (Athabascan) speaking, their name means "people of the red river" and also refers to the Chilcotin Plateau region in British Columbia. The Tsilhqot’in National Government is a tribal council established in 1989 that represents the six member First Nations of the Chilcotin Plateau. In 2014, the Tsilhqot’in people won a Supreme Court of Canada case that focused on the issue of Aboriginal title. In 2018, Prime Minister Justin Trudeau formally apologized to the Tsilhqot’in people for the wrongful conviction and hanging of Tsilhqot’in chiefs during the Chilcotin War of 1864.
