U.S. Science Gap Fictional?

James Cho writes "There are more science and engineering students than ever, says one Newsweek journalist. Inflated counts of Chinese and Indian students have created the myth of the U.S. science gap. While no gap exists yet, an exodus of retiring U.S. scientists could create one." From the article: "...a country's capacity for scientific and commercial innovation does not correlate directly with its number of scientists and engineers. Hard work, imagination and business practices also matter."
