Anyone with any interest in chemistry and the periodic table, look no further than a pound of your money and this application from the Nokia Store. Naveen CS have produced not only a stunning demonstration of what's possible with Qt but also a genuinely useful scientific aid on your Symbian smartphone. Screens and link below.
Here's Periodic Table in action:
The first view here is a fully pannable periodic table - it's interactive, in that tapping on any element dives into the detailed element properties, shown below. Very slick. (And AMOLED-friendly - well done!)
The other main view is a simple scrolling list of elements. As before, tap any to start diving into an element's properties. I loved the graphical scheme used, the detail and anecdotal touches.
Continuing the exploration of a particular element - showing even the diagrammatic electron configuration. Very, very cool, even if (as most chemists and physicists know) an actual atom looks nothing like this....!
There's also an element comparison tool - pick any two and then scroll through a side by side table of all their essential properties. Very slickly done and quite possibly a life saver for a busy chemistry student.
