I have an ongoing project to make posts for mental_floss articles I wrote way back when that I do not have an archive for. Here's one that was pretty special- it was the very first article I posted at mental floss exactly ten years ago today.
The internet is great for study aids, if nothing else. The periodic table of the elements is easier to study as an interactive table. Click on an element to retrieve all kinds of further information. Nice, but there are more imaginative minds working on putting the "able" back into the table. See them in the article at mental_floss.
