Kalzium – Video play feature
This is a cool feature that I have added to Kalzium. It will be really attractive in schools. I call it the play feature. You can basically play the periodic table like a video where you can see the temperature increase from 0 K to 6000 K gradually and see all the elements melt and eventually boil.
This is an addition to the somwidget. I have added the same feature to the Time-widget. When the play button is clicked on, you start from some year in the 1600s. The periodic table displays only the elements that had been discovered then. The year gradually increases to 1994 and stops.
To make things convinient, there is a pause button and the speed slider with which you can select the speed. The navigation slider already exists.
Here are some cool screen-shots of the same.
This is the som-widget, the temperature is currently at absolute zero. Red elements are solid at this temperature.
I start playing the periodic-table video, gradually some elements melt and some even boil. The blue elements are liquid at this temperature and the green ones are gaseous.
As we proceed this is what it looks like. The text area in the widget indicates the elements that melt or boil around that temperature with a threshold of 25 K.
Most elements have boiled here. Note the Grey boxes are elements whose values are unknown.
This is at 6000 K. This shows no solid or even liquid element at that temperature.
This is the time widget, at each year between 1664 and 1994, it shows the elements which had been discovered in blue and the undiscovered ones in blue.
Once again I hit the play button and start the video and, also increase the speed.
Many elements have been discovered at around this year you see.
1994 – Almost all elements have been discovered.
These are the features that will be available in KDE 4.3 probably. I am sure students will like it.
If you have any suggestions about this feature or an earlier feature, please comment.
Also suggest any additional feature if you wish to see it in Kalzium in the next release of KDE ( 4.3).
