For book forty eight of 2015, I enjoyed the book Big History: From the Big Bang to the Present.
This book was interesting from the perspective of what is presently believed of the origin of our solar system to the development of everything from the Big Bang to the present. What is also well done is the amount of coverage for the specific length of time compared to the proportion of actual history. How this is laid out really puts recent history into the overall perspective.
Recommended read, even if you’re looking to challenge your current perspective of Big History.
