Design isn't crafting a beautiful, textured button with breathtaking animation. It's figuring out if there's a way to get rid of the button altogether.

Here's the general theory: To clarify, add detail. Imagine that. To clarify, add detail. And clutter and overload are not an attribute of information, they are failures of design. If the information is in chaos, don't start throwing out information, instead fix the design.

That is to say, nature's laws are causal; they reveal themselves by comparison and difference, and they operate at every multivariate space, time point.

The speculative part of my work is that these particular cognitive tasks - ways of thinking analytically - are tied to nature's laws.

If you like overheads, you'll love PowerPoint.

My idea here is that, inasmuch as certain cognitive tasks and principles are tied to nature's laws, these tasks and principles are indifferent to language, culture, gender, or the particular mode of information that is provided.

A metaphor for good information design is a map. Hold any diagram against a map and see how it compares.
