    Magnetic Poles

    Because it behaves like a magnetized sphere, Earth has 2 magnetic poles. They are located near, but not at, the geographic poles, which are on the axis of Earth's rotation. The north and south magnetic poles are the locations on Earth's surface where the planet's magnetic field points straight downwards (at the north magnetic pole) and upwards (at the south magnetic pole). Conventional compasses which move on a horizontal plane are useless near the magnetic poles. However, a magnetized needle free to swing vertically will dip downwards at the north magnetic pole and point straight up at the south magnetic pole. For this reason, the magnetic poles are also referred to as the "dip poles."

    Male and Female Brains

    It began almost by accident. In an effort to uncover the causes of dyslexia, psychologist Sandra Witelson decided in 1970 to conduct an experiment involving dyslexic and other children at a Hamilton grade school.

    Manufacturing in Canada

    Manufacturing is a critical component of Canada’s economy. The production, sale and distribution of finished products contribute to consumer and labour markets, and secure Canada’s position as an economic leader among developed nations. Major, medium-sized and small manufacturers produce goods used by Canadians and contribute to the revenue gained from the export of goods to other countries. Since the early 2000s, the manufacturing sector in Canada has declined significantly in response to changes in the global economy and fewer regulatory controls over Canadian products (see Free Trade; Globalization). The composition and structure of the Canadian manufacturing industry is transitioning in response to these changes, aiming to produce new goods that are in greater demand.

    Mathematics

    Mathematics is the science of numbers and spatial relationships. It is customary to distinguish pure mathematics and applied mathematics. Pure mathematics can be divided roughly into three major fields: geometry and topology, algebra and arithmetic, and analysis. It is complemented by logic, which deals with sets, the basic mathematical objects, their axioms and rules of inference. This article provides background on mathematics. For more detailed information please see Applied Mathematics; History of Mathematics in Canada; Mathematics and Society.

    Media Bias in Canada

    Bias means supporting or opposing something or someone in an unfair way, regardless of the evidence. Media bias is when information spread by media or a news outlet reflects the interests and biases of ownership or individuals of that media company. Corporations may have a clear bias for one political party or issue and may influence its media outlets to reflect that bias. Individual journalists or news outlets may favour one side of an issue and reflect that bias — consciously or unconsciously — in the way they cover stories. The fact that a majority of journalists in Canada are White can also lead to biased reporting on minority groups. People can overcome unconscious bias by thinking and talking about it, and especially by listening to people from less privileged backgrounds.
