INCREDIBLE NUMBERS

Name: INCREDIBLE NUMBERS
Author: Ian Stewart

by Ian Stewart ; developed by TouchPress ‧ RELEASE DATE: March 27, 2014

bookshelf

TouchPress and Stewart offer eight challenging dives into mathematical theory and practice for readers not intimidated by complex formulas and brain-bending concepts.

Floating balloons on the opening screen lead to concise explorations of select topics in areas ranging from “Primes” to “Polygons,” “Infinity” to “Music.” In “Nature,” for instance, Stewart focuses on the discovery of the oddly similar but not identical “golden” and Fibonacci numbers and their occurrences in phenomena from sunflowers to spiral galaxies. Likewise, in “Infinity,” he covers set theory and other efforts to make sense of that concept’s bewildering paradoxes. Throughout, readers can tap highlighted names and special terms throughout to see definitions or biographical sketches. They can also search (with near-certain success) for their own birthdays in the first million digits of pi, create a message Enigma Machine–style in “Secret Codes” and experiment with harmonic intervals in “Music,” among other clever interactive demonstrations. The author swims easily through the sometimes-turbid sea of numbers, and the clean graphics, sharp photos and well-designed features that accompany his lucid explanations will help draw readers along in his wake. This may tempt even children who tremble at the sight of a square root to take the plunge. (Requires iOS 7.1 and above.) (iPad informational app. 14 & up)

RED-EYED TREE FROG

by Joy Cowley ‧ RELEASE DATE: March 1, 1999

bookshelf

Bishop’s spectacular photographs of the tiny red-eyed tree frog defeat an incidental text from Cowley (Singing Down the Rain, 1997, etc.). The frog, only two inches long, is enormous in this title; it appears along with other nocturnal residents of the rain forests of Central America, including the iguana, ant, katydid, caterpillar, and moth. In a final section, Cowley explains how small the frog is and aspects of its life cycle. The main text, however, is an afterthought to dramatic events in the photos, e.g., “But the red-eyed tree frog has been asleep all day. It wakes up hungry. What will it eat? Here is an iguana. Frogs do not eat iguanas.” Accompanying an astonishing photograph of the tree frog leaping away from a boa snake are three lines (“The snake flicks its tongue. It tastes frog in the air. Look out, frog!”) that neither advance nor complement the action. The layout employs pale and deep green pages and typeface, and large jewel-like photographs in which green and red dominate. The combination of such visually sophisticated pages and simplistic captions make this a top-heavy, unsatisfying title. (Picture book. 7-9)
