STEM Shortages, Purple Squirrels, and Le... This is the third in a series of articles that started with The Mathematics of the Ph.D. Glut. This article discusses claims of STEM worker shortages in private industry and how specific work-experience based skills are confused, intentionally or not, with general science and mathematics taught in schools...
The Ph.D. Glut is Bad for the United Sta... This is a followup to my previous article The Mathematics of the Ph.D. Glut. To recap, yes there is a Ph.D. glut in nearly all STEM (Science, Technology, Engineering, and Mathematics) fields in the United States. As a matter of federal government policy, many more Ph.D.’s are produced than can be...
The Mathematics of the Ph.D. Glut... I recently had a conversation at a get-together with someone whose sister had just started a Ph.D. program in biology. I discussed some of the unpleasant realities of graduate school today and referenced Brian Vastag’s July 7, 2012 article in the Washington Post “U.S. pushes for more scientists,...
