"Science explicates, poetry implicates. Both celebrate what they describe." Le Guin's quote, introduced on the half-title page of the book, serves as an incisive statement of purpose. Popova utilizes scientific understanding and poetic works in tandem to construct a full picture of 15 theories, forming a reflective, enlightening narrative that has furthered my awe of the universe. I also appreciate her inclusion of various female scientists and poets in her stories, it was great learning about the fantastic works of these women who are so often left out of history.
