5.0

I was initially drawn to this book not so much out of interest in learning about string theory specifically, but rather due to its well-earned reputation for explaining principles of physics in a straightforward manner, often through the use of creative analogies and metaphors. Through high school and college physics classes, not to mention through reading popular science books and watching the occasional educational YouTube video, I’ve encountered many different, though frequently overlapping, methods of teaching scientific theories like special relativity and quantum mechanics, but Greene’s explanations were some of the best I’ve come across. Despite the many daunting topics the book covers, it remains mostly accessible to readers without a deep background in science or mathematics.

What also makes Greene a great science communicator is his ability to anticipate the points of a concept that would confuse the reader and subsequently proactively address it. For example, when he explains time dilation, he first uses an example to show the consequences of the phenomenon in action and how special relativity overturned the classical perception of time. However, he then takes a moment to examine what would have happened in the situation if special relativity did not exist. I personally find this sort of compare and contrast description very effective.

Unfortunately, some of the later chapters were a bit more opaque, particularly when he dives more into topology and M-theory, but I finished the book with a better sense of the promise of string theory, some of its startling implications, as well as the many obstacles it faces in its development. Ultimately, I was left with a renewed sense of wonder at just how strange the universe is and at the strange new frontiers to which string theory would take our understanding of it.
