In corporate and government bureaucracies, the standard method for making a presentation is to talk about a list of points organized onto slides projected up on the wall. For many years, overhead projectors lit up transparencies, and slide projectors showed high-resolution 35mm slides. Now "slideware" computer programs for presentations are nearly everywhere. Early in the 21st century, several hundred million copies of Microsoft PowerPoint were turning out trillions of slides each year.
Alas, slideware often reduces the analytical quality of presentations. In particular, the popular PowerPoint templates (ready-made designs) usually weaken verbal and spatial reasoning, and almost always corrupt statistical analysis. What is the problem with PowerPoint? And how can we improve our presentations?
"Because this is a garden where things can be left out at night without being stolen, we're going to 'furnish' the garden with French café chairs that won't be secured in the ground, so people can move them to wherever they want to sit...It's like with the chairs being totally casual and relaxed and comfortable. They set a tone. There's things that you have to do to get the right feel, where it's all already there, but then, you know, 'Bing!' – there's a moment of recognition." The patterning of chairs pulled together in different ways by successive waves of visitors over the course of the day becomes an index of the shifting patterns of people that sit in a variety of arrangements to facilitate conversations and other intersubjective alignments, or simply to allow for a moment of private contemplation free from contact with others.
