Italics are used widely in mathematics and science; it’s how variables are typeset. However, it turns out that italics are often used where they shouldn’t be. I’m sure most scientists could happily live their lives without ever learning about the following examples of incorrect uses of italics. But as all scientists should know: minor details matter.
Several characters are simply short horizontal lines: the hyphen -, the minus sign −, the en dash –, and the em dash —. Each has a specific purpose, but often the hyphen is used regardless. This is bad practice.
The dash is not the only culprit; various other characters are incorrectly used. Typically these relate to mathematics or scientific quantities.
Writing about science often involves using symbols. Unfortunately, few of the symbols we need can be found on the keyboard, which presents a problem. It is not difficult to copy and paste symbols needed, but it is tedious and annoying. Here I present a solution that lets you input any symbol by simply typing its name (prepended with a slash).
