Exactly a century ago, in April 1911, Kamerlingh Onnes discovered superconductivity — the property of certain materials to conduct electricity with zero electrical resistance, and which is capable of causing certain objects to levitate. Superconductivity has been the subject of intensive research at ESPCI ParisTech for decades. To celebrate the centenary of the discovery, several events have been organized at the School, with a range of films, exhibitions, and creative activities. Some are factual and others are more fanciful. Here’s a review of the initiatives and a small selection of links.
