The word "community" may sound archaic, a social remnant of the idyllic 1950s. But paradoxically, in our high-tech age of instant information, "community" is more relevant than ever, though its broader boundaries and greater diversities may surprise you. Today's panelists explore communities in all forms, from political and social to scientific and technological. Joining host Robert Lawrence Kuhn are founder and president of the Discovery Institute Bruce Chapman; social architect Barbara Marx Hubbard; Yale Law School student Saru Jayaraman; linguist John McWhorter; and astrophysicist Neil deGrasse Tyson.
