Killing Time

As you’ve probably heard, ScienceBlogs is going to be silent for a day or two starting… 1pm today I think? I’m not sure, I don’t pay attention very well at our board meetings. And by board meetings I mean whatever happens to get posted on the internal message board. But apparently we’re upgrading the posting…

Hunting and Animal Size

This one’s a little of the beaten path for this site, since it’s not physics or even anything I normally follow as a hobby. But along with science and many other things I’m a bit of a firearms enthusiast, and since guns are closely connected with hunting it probably wasn’t unlikely that I’d come across…

Reader Scott writes in with a good question that I’ve heard posed by several people in various places, because it really goes to the core of the counterintuitive nature of relativity. Okay, let’s assume I’m in a spacecraft moving at a speed of c-1 m/s. That’s one m/s less than the speed of light. Would…

Football and Error

Over at Uncertain Principles, Chad is talking football. There’s this pesky problem of spotting the ball at the end of the play. In a game where fractions of an inch can make or break the end result, too often the issue is determined by a more or less random guess by the referee of where…

Unyielding Hierophant

The Constant Fire: Beyond the Science vs. Religion DebateAdam Frank Adam Frank is an astrophysicist and a man on a mission. It’s a brave mission, one which cuts strongly against the grain of the science vs. religion zeitgeist. It’s probably a mission which won’t succeed. Beyond the Science vs. Religion Debate is the book’s subtitle,…

Happy New Year!

Real-life physics can be a pain. New Year’s Eve I went with an old high school friend of mine to meet some people and shoot fireworks. This concluded at a little before one in the morning, and after that we left. We wanted to catch up on what had been happening some more and so…
