Dimopoulos: Beyond the Standard Model
The standard model of particle physics is a self-contained picture of fundamental particles and their interactions. Physicists, on a journey from solid matter to quarks and gluons, via atoms and nuclear matter, may have reached the foundation level of fields and particles. But have we reached bedrock, or is there something deeper?
For all its successes, the standard model is nevertheless unsatisfying. There are 18 or so free parameters, such as the electron mass, that seem arbitrary: they have to be determined experimentally. What is the origin of the masses of the fermions? How can the strong and electroweak interactions be unified? And what of the gravitational force, on which the standard model is silent?
In 1981 Savas Dimopoulos of Stanford University and Howard Georgi of Harvard University proposed the...

Korean Science Ascendant: Output, Impact Trending Upward
 n recent years South Korea has steadily increased its share of the world's scientific literature, according to a new Science Watch survey. In output of published papers, South Korea now surpasses Taiwan and other neighbors in the Pacific Rim. This increase has been accompanied by a rise in the number of highly cited papers produced by South Korean institutions, as well as an upward trend in the nation's citation impact in key
