The Problem of Exascale Computing

Computational physicists are already looking to the next milestone on the horizon: exascale computing, or supercomputers whose performance peaks in the exaflop range. But we need to get a lot better at parallelization before we can successfully compute at the exascale level.

The Sequester and the Research Scientist

The federal budget sequester is symptomatic of a larger dysfunction.

2012: My Favorite Doomsday Scenarios

Let’s be serious for a moment: nothing dire is going to happen on December 21st. Rest easy. But in celebration I’ve decided to count down my top five favorite astronomical doomsday scenarios, ordered from most to least plausible.

Top 5 Last-Minute Astronomy-Themed Halloween Costumes

Oh crap! It’s Halloween night and you don’t have a costume, because you’ve been inside doing astronomy all week! What should you do!? Never fear: Astrobites has got your back.

Zeno’s Paper, Or, The Paralysis of Analysis

You have likely experienced analysis paralysis, though just as likely you have not heard it called by that name. It can be as simple as trying to buy laundry detergent at the supermarket or as complex as trying to publish a key piece of research. And it all stems from the basic fact that the human brain is bad at graph traversal.
