Hi All, Last year we created a YouTube channel of Khan Academy-style videos, to teach Mineralogy online, or otherwise help students study and review. Those videos can now be found at a new channel, titled “Mineralogy and Earth Materials”: https://www.youtube.com/channel/UC7uoDeYnAw_4G_JbbpQ7j9g The videos can still also be found at my channel: https://www.youtube.com/channel/UC7uoDeYnAw_4G_JbbpQ7j9g, but the new channel avoids the accumulating clutter, and looks more like the public venture it was intended to be. Thanks to John Dilles, Cin-Ty Lee, Dexter Perkins, Rachel Teasdale and Jen Wenner for contributing. As before, we welcome new contributions as a diversity of thought is surely beneficial. If you see a hole or a flaw in content (crystallography being just one obvious case), please let us know and consider contributing. Take care, Keith Keith Putirka Dept. Earth & Env.
