I don't know a lot about love. And I know even less about math. So I assumed The Mathematics of Love: Patterns, Proofs, and the Search for the Ultimate Equation would be an interesting read for me, and I was right. Author Hannah Fry found a major similarity between love and math. and that similarity is patterns. Love being full of patterns, and math being the study of patterns. This is more a book about human behavior than a boring book about patterns. So if you aren't an intellectual per say, that's okay. The Mathematics of Love was very readable, fun, and may help you find your "perfect" equation.
And now I'll be able to show my high school kids how they can use math in real life.
