I once attended a scientific talk where someone started off by stating that he had given himself an award, a clip art ribbon, for busiest title slide. Sure he was joking, but I was cringing. Sadly this is just one of far too many examples of slides that I’ve seen that would look more at home in a kid’s scrapbook than a scientific talk.
By default, LaTeX produces professional-looking documents. Specifying an extra couple of packages, however, can make your document look even better. Here are four packages I recommend that require no effort, by which I mean you simply add the package to your preamble (and maybe specify a few options) and you’re good to go.
When designing any figure with colour, consider the Hue-Saturation-Lightness (HSL) colour space. It is the most intuitive and simplest colour space to work with. For examples of why it is well suited to scientific figures, skip to the bottom. To learn the details, read on.
LyX is a document processor that provides the power and professional-looking typesetting of LaTeX with the familiarity of an easy-to-use graphical interface à la MS Word. Effectively, it provides the best of both worlds. For someone without knowledge of LaTeX, LyX is less imposing and has a smaller learning curve. But even seasoned LaTeX users who have no desire to leave their favourite text editor can take advantage of some of LyX’s features.
Colour figures in journal articles are common these days. Many of the people reading them, however, will print them in black and white. Consequently, when designing figures, we should ensure they remain meaningful if converted to grayscale. Here are a few tips to keep in mind.
Outline slides in scientific talks are unnecessary and cut into a speaker’s valuable time. Many scientific talks are 10–12 minutes, and spending a whole slide outlining the next 10 minutes is pointless. Why? Because your talk is very likely going to follow a standard order: You’ll start with some motivation, move onto the background, present your results, then finish up with what you have concluded. This is what the audience is expecting, so don’t need to waste time reiterating. As an audience member, I prefer you use this time to teach me something.
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.
