The first application to make use of Wolfram Alpha for e-books is the visually stunning iPad version of Theodore Gray’s best-selling The Elements: A Visual Exploration of Every Known Atom in the Universe. The e-book application integrates Wolfram’s computational knowledge engine closely into the e-book experience. It’s easy to imagine calculus, engineering or geography textbooks that will also make use of Wolfram Alpha’s vast data repository and its ability to manipulate this data.
