J. Arthur Thomson - Outline of Science, Vol 1

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 Outline of Science, Volume 1 has consistently ranked in the
«Top 100 EBooks» category.
