Over at my Watered Down Physics blog, I have written a number of essays over the last several months on the Big Bang and Inflationary Cosmology. I am neither a physicist nor astronomer, but I enjoy reading books on these topics intended for a general educated audience. I then attempt to distill the ideas I read about into essay-length treatments. I always make sure to stick closely to my sources, hence you'll see a lot of page citations and web links. Here are my entries, with the dates they were posted: January 1, 2008: Introduction to the series; Georges Lemaitre's early ideas January 19: Redshifts March 30: Big Bang vs. Steady State model May 7: Cosmic Microwave Background, Part I May 10: CMB, Part II May 24: CMB, Part III June 18: Cosmological Constant July 6: Alan Guth's Inflation model I hope you enjoy these.
