Achever l'inachevable

In 1956 Dutch artist Maurits C. Escher challenged the laws of perspective with his graphic Print Gallery, and found himself trapped by an impossible barrier. His uncompleted master-piece quickly became the most puzzling enigma of modern art, for both artists and scientists. Half a century later, mathematician Hendrik Lenstra took everyone by surprise by drawing a fantastic bridge between the intuition of the artist and his own, and completed Escher's work mathematically. This story was made accessible to all audience and most magically presented in the award-winning 52-minute film Achieving the Unachievable by documentary filmmaker Jean Bergeron.
