![]() By their nature, they are large format, one slide to a page (or many, if you use Beamer, since each \pause command starts a new page in the PDF). Then came the photocopier, which took the pain out of duplication high-quality laser printers and LaTeX did the same for preparation.īut reproducing slides has always posed problems of its own. Once, lecture notes were handwritten or typed onto stencils, and duplicated by machines using even more unpleasant chemicals. Technology has changed things here as well. ![]() For seminars or conference presentations, a copy of the slides might be better. But this effort, while fine for teaching, is not always appropriate. I’ve always regarded lecture notes as not identical to what I write on the board or display on the screen, and write them with some care. What about the production of lecture notes or handouts? Mathematicians like the current set-up because the Beamer package gives us access to all the facilities and power of LaTeX. Now OHPs are a health hazard: not, as you might think, because you might injure your back picking them up from the floor, or because you might trip over the lead, but because you might walk through the beam and damage your eyes.Ĭurrently, computer and data projector rule, until they are superseded by the next thing, which might be some sort of smart paper. ![]() Originally these tried to emulate boards: the acetate was on a roll, and you could turn the handle as you went and write continuous text, and could scroll back (the word seems more fitting for this than for a computer screen). It was replaced first by whiteboards, whose pens originally used foul-smelling chemicals (they have improved but I am not convinced they are healthier than chalk). The original lecture technology, writing on a blackboard with a piece of chalk, is hopelessly old-fashioned now, though I still prefer it for teaching. During my career I’ve seen great changes in the presentation of lectures and the production of handouts. ![]()
