• We incorporate Wikipedia documents through single-bracket notation. As example, note [Senegal] and [First law of thermodynamics]. When understanding is truly essential, we may manually add a web link.
• We subscribe to the recent style change that White and Black should be capitalized when referring to ethnicities. Other ethnicities are capitalized as being based on the term for a country (such as Chinese or Iranian) or continent (such as Asian or African), these should be capitalized for consistency.
