The Outline of Science, Volume 1 was written specifically with the man-on-the-street in mind as the target audience. Covering scientific subjects ranging from astronomy to biology to elementary physics in clear, concise and easily understood prose, this popular science work is largely as relevant today as when first published in 1922. Special emphasis is given to the principles of biological adaptation and evolution, especially how they relate to the rise of the human species from lower orders. Also included are the basics of the (then) fairly new concept of relativity and its impact on emerging scientific theories.
Since first posted at Project Gutenberg in 2006, the text of
The Woodpeckers is a wonderful introduction to the world of bird study for the young naturalist, covering such topics as how he finds food, courting, how he builds his nest, the interesting ways he uses his different body parts as tools, among other topics discussed in the book.
If you wish to investigate further, the book has a few diagrams and an Appendix that contains more technical information such as detailed descriptions of the different species of North American woodpeckers which were not read as part of this audiobook.
