Desc: A Beautiful Equation: Directed by Robin Truesdale. With Len Barron. A Beautiful Equation follows eight elder women as they rehearse for an unlikely stage presentation about two great physicists - Albert Einstein and Niels Bohr. The grandmothers give vivid expression to the personal lives of the scientists in this delightful film, spinning the tales of Einstein and Bohr with grace, depth, and wit!. Their stories and experiences remind us that one doesn't need to be a genius to be fair, or playful, or to do things beautifully.
