On the morning of Oct. 5, President Bush and his education secretary, Margaret Spellings, paid a visit, along with camera crews from CNN and Fox News, to Friendship-Woodridge Elementary and Middle Campus, a charter public school in Washington. The president dropped in on two classrooms, where he asked the students, almost all of whom were African-American and poor, if they were planning to go t...

We walk on two legs, carry around enormous brains and have colonized every corner of the globe. Anthropologists and biologists have long sought to understand how our lineage came to differ so profoundly from the primate norm in these ways, and over the years all manner of hypotheses aimed at explaining each of these oddities have been put forth. But a growing body of evidence indicates that the...

We report measurements of the action associated with center vortices in SU(2) pure lattice gauge theory. In the lattice units the excess of the action on the plaquettes belonging to the vortex is approximately a constant, independent on the lattice spacing a. Therefore the action of the center vortex is of order A/a, where A is its area. Since the area A is known to scale in the physical units,...
