Thank you for this thread! I think that this is a great challenge from your friend.
Understanding history is critical for anyone who wishes to grasp a larger view of the world around them. To understand the human journey we need to know what people have done before us. The present reality we find ourselves in is built on the tapestry of all that came before it. What is realy thrilling, is to combine the social and natural sciences together to really start to build a vibrant framework of what has happened, is happening, and might happen.
