Prologue

On a Tuesday of May 2002, my wife was mowing the lawn. I was half-asleep, laying on the couch. (It was not my turn.)

I forced myself up and went to children’s room upstairs. There were big Lego blocks on the floor, spread freely after children’s play. I gathered dozens of them and started constructing a maze to a large Lego board. The maze turned out to be simple but complicated enough to function and be labeled as one.

I went to the kitchen, opened the tap water, letting it drop slowly and smoothly. I positioned the maze’s starting point under the stream letting water to spread around the maze. The Lego block construction was not completely water-proof; a tiny amount of water found its way out of the maze via small gaps beneath the blocks.

Water filled each corridor and turn of the maze, and was slowly flowing, exiting the maze from the open end to the kitchen sink.

I took a small thing, probably a grain from a bread, and dropped it to the stream at the maze’s starting point. It sank to the bottom. I tried an another small thing - I do not know what it was but it floated. The stream carried the unknown thing of kitchen dirt through the twists and turns of the labyrinth, guided it out, to the sink. The stream solved the task.

This mildly unscientific sunny afternoon experiment was the final threshold impulse to start writing this book.

Now on 2008, the book starts to turn into a blog, gradually, chapter by chapter…
