Compound Interest

I have a great appreciation for good design, particularly for good design with a purpose. Compound Interest is such a site, full of chemistry infographics with a pretty design sense, all produced by a British chemistry teacher (or instructor or lecturer or dustbin - whatever the British call chemistry teachers over there).

At the top of this post, we get a timeline of the element discoveries with flags so you can see where the element were discovered.

There's also this post of colours (again, British natch) that are visible during metal ion flame tests...

...and this one of the major chemicals found in herbs and spices...

...and a hundred other infographics. Supposedly there's going to be a book coming in the fall, but it hasn't gotten to the pre-order stage just yet.
