Decades ago I read that it was impossible to visualize a four dimensional Euclidian space. I decided to try to do that. It isn't possible to see a 4D space as a native would -- we don't have 4D hardware -- but through various tricks one can do better than nothing. So I wrote a book about the results and had it illustrated.

The book is based on the 19th century mathematics of William Clifford. Math is death in the marketplace so the book contains none of that, just the effects. What surfing would be like, what pizza or automobiles would be like, things like that. There is a website occupied by the five or so mathematicians who are interested in this so I got one of them to approve of the manuscript. I've earned a masters degree in math from a fancy university and the math is quite simple, basic linear algebra, it's just a question of how to visualize the results. The main difference is that according to Clifford things in a four dimensional universe rotate quite differently. The exotic rotation of a 4D Earth would have big effects on everyday life and climate. In 4D a rifle would offer no advantage over a musket. Be assured that I don't claim any such 4D objects could exist, it's strictly a pedogogical tool, an intellectual exercise. If you can't imagine what everyday objects would have to be like in a 4D universe, then can you say you really understand 4D?

When it got to the point of advertising the book I found out that I couldn't stand doing that, so I decided to give it away free. I've had a few readers, but it would be nice to have more than five. It's not about our universe so it isn't physics. There are no characters or plot so its not what people would expect from science fiction. The world building community might be interested but having an extra spatial dimension is radical. This would be for people who want to have their minds boggled. What would you suggest I do to find those few who would be interested?
