Las Vegas Motor Speedway
On October 16, 2011, the final race of the 2011 IndyCar season, the IZOD IndyCar World Championship, was held at Las Vegas. However, the race was halted by a horrific crash on lap 11 that involved 15 cars, some of which became airborne, and some of which burst into flames. The crash began when Wade Cunningham made light contact with James Hinchcliffe, but the situation turned into a big pile-up of cars. The crash allowed a red flag to be waved almost instantly, due to the remains of the damaged cars and the amount of debris on the track.
International Conference on Database Theory
The International Conference on Database Theory (ICDT) is an international research conference on foundations of database theory, and has been held since 1982. It is frequently also called as the PODS of Europe. Since 2009, ICDT has been held jointly with the EDBT, a research conference on systems aspects of data management. Until 2009, the conference used to happen biennially. The conference now happens annually at a location typically within Europe. ICDT has been instrumental in developing a flourishing research community within Europe, working on problems in database theory.
