Have you ever been frustrated by the difficulty of representing antiparticles in a Microsoft Word document, where you have to resort to writing “-bar” after the letter denoting the particle – for example as in K-bar? Now help is at hand, at least for Apple Macintosh users, in the form of a font that allows bars, or “overlines”, to be added to English characters and the most commonly used Greek characters. Physicists from the University of Mississippi in the US have developed the font, LinguistA, which allows you to make a K-bar, for example, by simply typing shift-5 followed by K.
