The Elements: A Visual Exploration lets you experience the beauty and fascination of the building blocks of our universe in a way you’ve never seen before. You start off at a living periodic table where every element is shown with a smoothly rotating sample. To read about tin, tap the tin soldier. To read about gold, tap the gold nugget. Immediately you see the sample filling nearly the entire screen, photographed to razor sharpness and rotating around a complete circle in front of your eyes. Beside that is a column of facts and figures, each of which can be tapped to bring up rich detail and current information through the embedded Wolfram|Alpha computational knowledge engine. Tap the Wolfram|Alpha button for gold and it tells you the up-to-the-minute market price, along with a hundred other facts about gold. But it’s when you go to each element’s second page that the real magic starts. Carefully photographed objects representing the element fall down, rotating a fraction of a turn as they settle in to form a beautifully composed page. Every one of these objects, well over 500 in total, is a freely rotatable, live object that you can examine from all sides. By Element Collection, Inc.
