Widget watch: Elements
I could have used this when I was in school. This week, Digital Science released the Elements Widget, which is a companion to their Elements Periodic Table application. The widget displays information (such as symbol, name, atomic number, atomic weight and phase under standard conditions; all IUPAC conformed) with a click on any element. Plus, if you've got the application installed, you can jump directly from the widget to the app itself. It looks pretty nice, too. Check it out.
