I think I've introduced enough language to talk about both the issues relating to the Coleman-Mandula theorem, and about the mixing of fermions and bosons. The latter is related to what's called BRST quantization. The catch is that what Lisi says about this makes no sense to me. It might be that there's more to BRST than what I studied years ago. But my objections seem to be shared by people who know lots more physics than me.&lt;BR/&gt;&lt;BR/&gt;I guess I could title my post "Some uncertain thoughts on...."</content><link rel='edit' type='application/atom+xml' href='http://www.blogger.com/feeds/11295132/5418131944332046488/comments/default/3252844729749951567'/><link rel='self' type='application/atom+xml' href='http://www.blogger.com/feeds/11295132/5418131944332046488/comments/default/3252844729749951567'/><link rel='alternate' type='text/html' href='http://blog.sigfpe.com/2007/12/whats-all-this-e8-stuff-about-then-part.html?showComment=1197505680000#c3252844729749951567' title=''/><author><name>sigfpe</name><uri>http://www.blogger.com/profile/08096190433222340957</uri><email>noreply@blogger.com</email><gd:image xmlns:gd='http://schemas.google.com/g/2005' rel='http://schemas.google.com/g/2005#thumbnail' width='32' height='24' src='http://homepage.mac.com/sigfpe/.Pictures/Photo%20Album%20Pictures/2002-12-07%2014.53.40%20-0800/ImageDSC01397_1.jpg'/></author><thr:in-reply-to xmlns:thr='http://purl.org/syndication/thread/1.0' href='http://blog.sigfpe.com/2007/12/whats-all-this-e8-stuff-about-then-part.html' ref='tag:blogger.com,1999:blog-11295132.post-5418131944332046488' source='http://www.blogger.com/feeds/11295132/posts/default/5418131944332046488' type='text/html'/><gd:extendedProperty xmlns:gd='http://schemas.google.com/g/2005' name='blogger.itemClass' value='pid-961546855'/></entry><entry><id>tag:blogger.com,1999:blog-11295132.post-7519902608930321360</id><published>2007-12-12T15:16:00.000-08:00</published><updated>2007-12-12T15:16:00.000-08:00</updated><title type='text'>Indeed, thanks for the great series!
