Orbitals

By
Here's a cute orbital dynamics simulator:

Try some of the presets, or make your own system. Ain't gravity fun?!

I just wish you could specify the periods and eccentricities, rather than the initial velocity vectors...

I wasted 15 minutes of my morning playing with this, during which time I discovered that I'm not very good at gravity. Once I even managed to eject *all* of the bodies from the system!

A view from your shut down

By
The Daily Dish has been posting reader emails reporting on their " view from the shutdown ." If you think this doesn't affect you, or if you know all too well how bad this is, take a look at the growing collection of poignant stories. No one is in this alone except for the nutjobs in the House. I decided to email Andrew with my own view. I plan to send a similar letter to my congressperson. Dear Andrew, I am a professor of astronomy at the Harvard-Smithsonian Center for Astrophysics (CfA). The CfA houses one of the largest, if not the largest collection of PhD astronomers in the United States, with over 300 professional astronomers and roughly 100 doctoral and predoctoral students on a small campus a few blocks west of Harvard Yard. Under the umbrella of the CfA are about 20 Harvard astronomy professors, and 50 tenure-track Smithsonian researchers. A large fraction of the latter are civil servants currently on furlough and unable to come to work. In total, 147 FTEs

The Long Con

One of the major "leaks" turns out to be con artists, who lure athletes into elaborate real estate schemes or business ventures. This naturally raises the question: In a tightly-knit social structure that is a sports team, how can con artists operate so effectively and extensively?

I've lost money in two different con schemes. One was when I was in college, and I received a phone call that I had won an all-expenses-paid trip to the Bahamas. All I needed to d

back-talk begins

By
me: "owen, come here. it's time to get a new diaper" him, sprinting down the hall with no pants on: "forget about it!" he's quoting benny the rabbit, a short-lived sesame street character who happens to be in his favorite "count with me" video. i'm turning my head, trying not to let him see me laugh, because his use and tone with the phrase are so spot-on.
