How many airline flights did Superstorm Sandy disrupt?
More than 16,000 flights were canceled because of the rain, wind and snow that Sandy delivered between Saturday and Wednesday. At least seven airports were completely shut down, including JFK in New York and Chicago's O'Hare.

The cancellations topped the 15,000 flights canceled in August 2011 when Hurricane Irene struck.
What is the fastest computer in the world?
The computer industry will announce the fastest supercomputer next month, but a leading contender is the Titan system used by the U.S. Department of Energy's Oak Ridge National Laboratory in Tennessee, National Geographic reports. The computer can handle 20,000 trillion calculations a second. That's the equivalent of 1,000 people doing one calculation per second for 60,000 years, or all 7 billion people on Earth each doing 3 million math problems per second.
