More items of interest

This continues to be a very very busy time, but here are a few interesting things to read:

• "Voodoo fusion" - an article from the APS Forum on Physics and Society that pretty much excoriates all of the fusion-related startup efforts, basically saying that they're about as legitimate as Theranos.  Definitely an interesting read.  
• https://arxiv.org/abs/1910.06389 - This is Kenneth Libbrecht's tour de force monograph on snow crystals.   Talk about an example of emergence:  From the modest water molecule comes, when many of them get together, the remarkable, intricate structure of snowflakes, with highly complex six-fold rotational symmetry.
• Somehow this tenure announcement just showed up in my newsfeed.  It's very funny, and the titles and abstracts of his talks are in a similar vein.  Perhaps I need to start writing up my physics talks this way.  
• Beware of unintended consequences of ranking metrics.
• https://arxiv.org/abs/1910.05813 - insert snarky comment here about how this is a mathematical model for hiring/awards/funding/publication.
