In this informational picture book, husband and wife team, Sarah and Richard Campbell, challenge readers to think deeply about the mathematical concept: “What is infinity?”

“Thinking about infinity is tricky. You have already thought of a large number and added one, but that might lead you to make the mistake of thinking infinity is something really, really big. Remember, though, infinity is not something big. Infinity is endlessness.”

Calculus is the branch of mathematics that puts infinity into practical use. NASA scientists use calculus and the idea of infinity when making the calculations to send rockets into space.

The marriage of words and pictures work exceptionally well here as the Campbell’s present the not-so-simple task of defining the concept of infinity. The book includes an author’s note, glossary, further reading(which includes websites and books), and an exercise - The Infinite School and the Surprising Results of Adding with Infinity.

“The next time you find yourself counting stars in the sky, remember that even though the number of stars is finite, your mind has no limits.”

Highly recommended reading aloud for older students.
