DESCRIPTION:Prof. Yves Meyer\nBio: Prof. Meyer was born in Tunisia in 1939
 \, before emigrating to France and entering an undergraduate school there 
 in 1957. After graduating\, he became a maths teacher at a small French mi
 litary school. In 1963\, he applied to a doctoral program in Strasbourg\, 
 France and\, over the decades\, hopped from school to school in France. Hi
 s mathematical inquiries were equally peripatetic: he developed important 
 theories in a wide range of fields\, including number theory and the Navie
 r-Stokes theorem\, which describes the flow of viscous fluids. Yves Meyers
  is professor emeritus in mathematics at the École normale supérieure Pa
 ris-Saclay in France. In 2017 he received the Abel Prize from the Norwegia
 n Academy of Sciences and Letters for his pivotal role in the development 
 of the mathematical theory of wavelets.\nFirst Campus Lecture EPFL - Prof.
 Yves Meyer (Dr Honoris Causa 2017): "The role of time-frequency wavelets i
 n the detection of gravitational waves"\n\nPerturbations of space-time met
 ric (gravitational waves) predicted by Einstein's theory of General Relati
 vity are steadily sent to the Earth. These ripples travel at the speed of 
 light through the Universe\, carrying with them information about their c
 ataclysmic origins. Before September 2015 such signals could not be detect
 ed. But on the 14th of September 2015 at 09:50:45 (UTC time) everything ch
 anged: gravitational waves were detected. They were produced during the f
 inal fraction of a second of the merger of two black holes to produce a si
 ngle\, more massive spinning black hole.\n\nTime-frequency wavelets are pl
 aying a seminal role in the detection algorithm\, as explained in this le
 cture. The tools which are used by Sergey Klimenko in the detection algori
 thm are the same which were developed by Henrique Malvar and others to pr
 ocess acoustic signals. This is a striking example of the Unity of Science
 .
