This series is about discovery, and the origination of what we take for granted. There is no in-depth treatise intended, but it reveals a path from the beginning of a technology, the advances along the way, and what we have now.
Personally, even with my strong science background, it was fascinating. I wasn't expecting an entire episode of how modern water purification works. That it started with contaminated water in metro areas and developed into the safest time in world history to drink tap water is what makes this series compelling.
Who knew the entire city of Chicago was raised to install a sewer system? How did that lead to subways? Beer is good to drink. Who created the modern time zones we use today? How was fiber optic technology developed?
I only wish there were more episodes to watch.
