Many of the posts in this blog depend on ideas developed in previous blogs. In each post I have tried to make these links easier by:

1. Suggesting previous posts that should be read first (at the beginning)
2. Indicating posts that provide further information on a topic (in the body of the post) or by linking you to the Index
3. Listing recent posts on related themes (at the end of the post).

The earlier posts probably make most sense if you start by reading them in the order in which they were written – starting with post 16.1.

But, as I have increased the scope and range of topics, I believe that it is better to be more selective and read only the posts that look interesting or useful to you.
