==Another revision? - prune artwork?== 
 The article is obviously the result of an homework assignment for a synthesis class which forced a large number of spacious drawings and a historical review of the kinds of epoxidations studied in universities.  There is virtually no mention of the important stuff - nothing on EO and PO production, no real world applications, no biology, reactions is thin.   
 Choices 
 *we could remove some of these images or  
 *we could split off an article on "olefin epoxidation" which could collect some of all of these nine images, which damage the current article (the images were shrunk by 1/3 here!) 
 *do nothing be thankful we even have this thing
