Motivation Monday: The Impossible Made Possible

There is a secret to solving any problem.  You may have learned it in school, but you didn’t know it at the time.  It’s not always explicitly stated in solutions to problems, and you may have done it by accident once or twice.  It is elusive, but seems obvious when you’re aware of it.  If you know how to use it properly, you can turn any impossible task into something doable. The secret is to break things down.  To take any problem, as impossibly huge as it is, and split it into smaller chunks, manageable steps, and workable pieces.  Doing this, any...

Hyperion the Sponge Moon

A couple of days ago, the still-active Cassini spacecraft orbiting around Saturn performed a flyby of the small Moon Hyperion, taking high resolution photos of the surface, and showing the sponge-like surface of the moon in a different light. Hyperion is a moderate 250 kilometers wide, yet it doesn’t tug very hard on Cassini.  Performing measurements of its surface gravity, Cassini has shown that the moon is mostly empty space, similar to a pumice stone on Earth.  The odd shapes of the craters are thought to be a result of this.  When an impactor hits Hyperion, it blows the material...
