This accessible volume provides readers - whether students new to the field or just interested members of the lay public - with the essential ideas of evolution using a minimum of jargon and mathematics. Concepts are introduced in a progressive order so that more complicated ideas build on simpler ones, and each is discussed in small, bite-sized segments so that they can be more easily understood.
Cosmology 101 introduces readers to all the aspects that make cosmology such a vibrant and dynamic field:
- The debate over whether the the Milky Way was the only "island universe", or only one of many "galaxies. The solution to this question set into motion a new revolution in cosmology.
- Albert Einstein's General Theory of Relativity, which has completely altered how scientists model the universe
- The debates over the Steady-State versus the Big Bang model of the universe, and the recent theories, such as the inflationary model of the universe.
This volume in the Science 101 series provides readers with a solid understanding of how scientist know what they know about the universe.
