Guns‚ Germs‚ and Steel Essay Guns‚ Germs‚ and Steel is an amazing book. When I first looked at it I told myself I would never be able to read it because it was so big‚ but I knew I had to. By the title I thought it was going to be about the Civil War. When I began reading Yali’s question I realized that it was about early civilizations and their advancements. When I started reading the book it was very boring and I didn’t know how I was going to finish it. As I got to around page 75 I began to

Superman (1978) and Man of Steel are two very different films that are based on the same idea. Both films were made in times where technology changed the quality of each film.

I first read Jared Diamond’s Guns‚ Germs‚ and Steel in the Fall 2003 based on a recommendation from a friend.
