Why, the elements, of course. So in this article, I focus on how you can learn more about the elements that make up everything around you with Kalzium. KDE's Kalzium is kind of like a periodic table on steroids. Not only does it have information on each of the elements, it also has extra functionality to do other types of calculations.
