* In 1905 Albert Einstein published three brilliant scientific papers, each of which had a profound effect on the development of the physical sciences. This year marks the centenary of that annus mirabilis. To celebrate the occasion, London's Ballet Rambert is to stage a production with the title "Constant Speed," expressing the great physicist's insights through the medium of dance. How, exactly, do you do that? Let the ballet's artistic director explain: "We've got lots of molecules bouncing around, and the stage--which starts out all in white--ends with all the colors of the spectrum, as the little packets of light that Einstein discovered are added one at a time." Ah. Is it not the case that under certain relativistic conditions, time slows down to a crawl, so that one minute can last an hour or more? Let us hope that "Constant Speed" will not have this effect on its audience when it premieres at Sadler's Wells in May.
