App of the week - The Elements

This is a visually stunning experience of the periodic table of all known elements. If you think you've seen the periodic table, think again.

Stephen Fry, review tweets: “Best App of all Theodore Gray Wolfram Periodic Table. Everything is animated and gorgeous. Alone worth iPad.”

Xeni Jardin of Boing Boing blogs “Itʼs dazzling—it makes science feel like magic in your hands.”

Starting point ...A living periodic table in which each element has a smoothly rotating sample, eg: a tin soldier for Tin.

“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.”

BGfL will be featuring an app each week which can expand the teaching and learning experience. We want to provide guidance on the use of mobile apps and touch technology - so as well as the use of iPhone/iPad apps, we are keen to share Android apps available for you to use.

If you have an app you wish to recommend, then let us know.
