All I can say is that I first had to look up the 3 body problem. As a fairly intelligent and literate history and sci-fi fan, not knowing about the book made me curious about the concepts behind it. Do I understand it? I can only appreciate the science behind it and hope that it stirs curiosity in someone, somewhere who may be able to advance the ideas.
Could it have been better? Maybe, probably, it is what it is and I appreciate it for the entertainment and for at least stoking my curiosity!
