Andy Brunning over at Compound Interest has created a great infographic to help explain some of the chemistry behind the Flint water crisis. The graphic is below, but I strongly encourage you to take a look at his full article

Andy’s post introduces a lot of concepts that could be incorporated into a Chemistry lecture, making it a potentially valuable resource for connecting what students may find as esoteric concepts to real-life situations.  Check out the full article while I jot down some ideas for exam questions….

Quite a while back, I used Jasper to create a speech recognition periodic table fun fact program.  That was before my website was revamped and I lost the original blog post.  (Well, I do have it in my backups, but it’s not really worth reviving at this point.)  I do have a video showing the results, however:

I’ve started to revisit this project, and here are my first thoughts…
