This talk was given at a local TEDx event, produced independently of the TED Conferences. What are asteroids and meteorites? What do we learn from them? Why to care about their past impacts on Earth and on other planets? How to, and can we, avoid potentially devastating impacts in the future? All these questions have some answers, but more fundamentally, what drives us to continue to explore these fields of research? Is it really the thirst for knowledge?
Ludovic Ferrière is a geologist, chief curator of the rock collections and co-curator of the prestigious meteorite collection at the Natural History Museum Vienna (Austria), and an expert on meteorite impact craters. Born in France, his explorations have taken him all around the world, allowing him to confirm the meteorite impact origin of two of the currently ~185 recognized meteorite impact craters on Earth.
About TEDx, x = independently organized event In the spirit of ideas worth spreading, TEDx is a program of local, self-organized events that bring people together to share a TED-like experience. At a TEDx event, TEDTalks video and live speakers combine to spark deep discussion and connection in a small group. These local, self-organized events are branded TEDx, where x = independently organized TED event. The TED Conference provides general guidance for the TEDx program, but individual TEDx events are self-organized.* (*Subject to certain rules and regulations)
