Those curious about the play Copenhagen and the real life events that inspired it should drop by Graduate Center of the City University of New York (365 Fifth Avenue) on March 27, when playwright Michael Frayn and director Michael Blakemore discuss the evolution of the Broadway bound work.

In Copenhagen, set in 1941, fellow physicists and one-time friends Niels Bohr and Werner Heisenberg meet to find they are on opposite sides of World War II. The play is based an actual occasion, though what actually transpired at the meeting is shrouded in mystery.

Joining Frayn and Blakemore on the panel will be Nobel Laureate physicists Hans Bethe and John Wheeler, and writer and physicist Brian Greene. For information on the 7:30 PM event, call (212) 817-8215.

The panel will serve as a preview event to the Ensemble Studio Theatre's second annual "First Light" festival of new plays addressing issues of science and technology. The fest runs April 5-30, and includes a premiere production of Arthur Giron's Moving Bodies, a drama about yet another physicist, Richard Feynman, who worked on both the Manhattan Project and the space shuttle Challenger disaster. Chris Smith directs.

Also feature in the festival are 11 play workshops and a studio production of Bob Clyman's The Secret Order. Tickets to Moving Bodies at $15. EST is located at 549 W. 52nd Street in Manhattan. For more information, call (212) 247-4982.
