- in graduate school in the early 80s part of my toolkit was being able to use a 35mm camera on a stand to take photographs of tables and pictures; they develop and fix the roll of film; then cut out each frame and mount it as a 2x2 [50x50mm] slide. These slides would be loaded into a carousel for projection during the talk.
- People were using over-head projectors OHP back then as well often to imply that their results were so cutting-edge that they hadn't had time to get them to the darkroom. You could scribble on a long roll of transparent plastic as if it was a black-board or you could copy stuff onto 'acetates' and slap these plastic sheets one-by-one on the OHP.
- Then in the late 90s, all that hard-copy was swept into the dustbin of history and we all had to learn how to use Powerpoint and carry our talks on a USB key.
I think my dates with Pat have come to an end because I'm back at work in The Institute and my current timetable has a class between 0900-noon on Mondays. Ho hum, sad enough but my commitment to The Youth must have precedence because that pays me and they're going to live longer. The Institute has lashed out €10 million on a new Teaching and Learning Centre which they have named after local man Samuel "Long-drop" Haughton [bloboprev]. I'll be teaching one class a week in the new building and attended an orientation session there last Thursday. There is no black-board! And no chalk. There is no white-board. The larger theatres have two projection screens (aka a large white wall) which can be worked in AND / OR mode. So you can, for example, show the same stuff on both screens or have the left screen showing a slide full of Powerpoint bullet-points and the right-screen carrying a video. And they have an epidiascope!! So Retro, darling. It doesn't have a chimney, though: it's basically a down-pointing camera like I used to make crude black&white 35mm slides 35 years ago. Except that this is a video camera. If I want to write something for display, I have to slap a slab of paper under the camera and scribble on that whence it will be broadcast in real time onto the wall behind me.
One of my waggish colleagues suggested that if our hands were going to appear 6 feet high on the wall, we'd better make sure our nails were clean. And that started a discussion about catching the dreaded lurgies from using a keyboard, wearing gloves to combat the same, sleeping in hotel beds and bringing an autoclave to restaurants for the cutlery. Unless we have OCD, most of us
