Antoine RemondTiedrez Carnegie Mellon University Title: Gravitational Waves Abstract: Earlier this year, physicists announced the first observation of gravitational waves, thus providing the first experimental verification of this phenomenon long predicted by the theory of general relativity. As for many other physical phenomena, the recipe leading to the theoretical prediction of gravitational waves can be summarized as "physical postulate + mathematical voodoo = surprising (and experimentally testable) insight".This talk will ultimately answer the question: "What the hell is a gravitational wave anyway?" And as we develop the necessary vocabularies and tools, we will see that much of the development of general relativity (aka applied differential geometry) indeed follows this pattern of "postulate + voodoo = insight".
