In the present study we employed both gradual and punctuated

The Second Term Room is subdivided into two facing chambers, the first punctuated

In putting forward this idea of "coordinated stasis," paleontologists Carlton Brett of the University of Rochester and Gordon Baird of the State University of New York, Fredonia, have built upon the concept of "punctuated
equilibrium." This revolutionary concept was advanced in 1972 by Stephen Jay Gould of Harvard University and Niles Eldredge of the American Museum of Natural History, in New York, who argued that species tend to persist unchanged for millions of years before abruptly giving way to new species.

For close to an hour, accompanied by Chris Lancaster's rich cello score, end less combinations of duets, groups, and solos formed and re-formed, racing, tumbling, or swooping through the space, punctuated
by moments of hilarity, thoughtfulness, or just plain silliness.
Wind gusts sporadically through the skinny pines to animate the suspended white cloth, daylight absconds, an ominous hum slowly crescendos, and, suddenly, as though the trees were dreaming, the putative zenith of pre--World War II Western sophistication blooms in the midst of Europe's oldest forest: On the blowsy sheet is projected Fred Astaire's famous dance sequence from Top Hat (1935), the orchestra's flourishes punctuated

Using a photonic crystal--in this case, a sliver of silicon punctuated
