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?
Historically, Japan's shrines have been built in order to worship the gods who live in the sacred mountains or seas; They don't reside in the shrine itself, but in the space beyond it. This belief that the spirits and deities exist beyond the confines of the shrine, and that the shrine itself acts not as a centre, but as a kind of gateway, is very different to the grand, imposing churches and cathedrals of Christianity.
The majority of shrines are not found in the mountains or in the middle of the fields, therefore, but at the borders of mountain villages – which is to say, at what is seen as the edge of the mountains. The tori gate, marking the entrance to a shrine, indicates that there are gods on the other side of it.
