10/10 Recommend
Format: Hardcover
I took Jeffrey Sachs's Globalization class on EDX Academy and somehow stumbled upon this book in between class and finding books around the subject.
I watched his youtube video that generalizes the book and was blown away by how my current class I was taking aligned with it.
This book is an easy read, and especially for those who aren't well-versed about world history and world economics. I will admit that I do love history, and am learning economics, so this book was a beautiful way merge all these timelines together.
The book breaks down and summarizes key points in world history and economics to make points to get the message across each chapter.
Font size is great! Might even be considered larger compared to other books.
The only thing I wish this book provided was thicker paper in the physical book itself, especially for the hardcover version.
If Ray Dahlio ever comes out with a special edition of this with a higher quality paper, I would gladly purchase it for my collection.

Excellent book – exciting and educational!
Format: Paperback
This book is a true gem! It took us on a journey back in time and revealed the real story of the Olympic Games in a simple, vivid, and perfectly understandable way for children. My young students loved it, and I found it extremely useful and well-written. Ideal for kids who love history, sports, or simply want to learn something different in a fun way.
Highly recommended!
