Holdren, STEM, and lifelong learning

"Strengthening STEM education at every level, from precollege to postgraduate to lifelong learning" is one of four "cross-cutting foundations of success" for John Holdren, new science advisor to the President. It's nice to see a one-sentence encapsulation of STEM education that emphasizes learning throughout a person's life. Improvements at the K-12 level are necessary, but not sufficient, for innovation and competitiveness.
