With my first printed and bound work sitting on the desk beside me, I might be forgiven for having delved a bit into typography and printing. Most people will be familiar with Helvetica, one of the most commonly used sans serif fonts in history. Fewer will know as much about it as is provided by this article. Quoted therein is Eric Gill, the British sculptor who designed the font I ultimately chose for my thesis. More on Helvetica can be found on Metafilter.
Typefaces have an interesting effect on the presentation of data. Usually, the differences between them are subtle enough to evade perception. Nevertheless, the shape they give to individual words or whole pages of text immediately conveys a great deal of information about the source: in terms of elegance, audience, and approach.
