The Independent Recommends: Theatre

WITH ITS FUSION of scientific terms and stark design, Copenhagen might seem like a physics masterclass, but Michael Frayn's (below) imagining of the 1941 meeting between the German physicist, Werner Heisenberg, and his Danish mentor, Niels Bohr, in occupied Denmark is so expertly conducted that the dry exchanges about nuclear research mushroom into a gripping study of mankind's slippery nature.

Another three-hander tackling science head-on, this time from a real scientist. After a succession of novels, Carl Djerassi, who synthesised the Pill in 1951, has turned his hand to a play. An Immaculate Misconception - which looks at the latest in-vitro fertilisation treatments - promises to be an alternative to the usual fluff of the Edinburgh Festival Fringe, which is now under way.
