This Month in Physics History: Louie de Broglie
Every month I get the APS News (the dead-tree version, which I can carry on the subway), and the two parts I always read first are the Members in the Media (link is to Oct 2010 issue) and This Month in Physics History. Both of these sections help in putting a personal face on physics, …
ZIP Recovery Tools – Not *Exactly* an Endorsement
I was going to make this just a comment on my previous blog entry, but after spending a couple of hours trying various tools and making notes, the "comment" was getting longer than the original post. So it gets it’s own entry. I’ve kept poking at various tools to try to recover some of my …
Windows XP Ate My Images
In order to save space on my Windows XP laptop, which I use for a lot of my imaging, I used the built-in compression to zip up the entire directory tree from the 2009 Summer Star Party. When all was done, the final archive was nearly 4 GB. Nearly, but not quite. To my horror, …
Site upgrade rolled back
After fighting for a week, I’ve rolled back the Drupal upgrade. Since I posted nearly nothing in the past week (except some comments on the upgrade woes and one event listing which was more of a test), nothing was really lost. I’ll be doing this upgrade the more traditional way which is by staging it …
Life in the Fast Lane?
I don’t think I’m actually in the fast lane, but it sort of feels like it. The past month has had me away for two weeks, one with the Cub Scouts in Alpine, NJ and another at the Summer Star Party in Savoy, MA. Between that and being in physical therapy three days each week …
Modeling the Moon’s Phases
I originally built these models a couple of years ago, but didn’t realize it was something “novel” until I got some comments at this past year’s NEAF where I had brought them for the children’s section. Quite frankly, I think it works well with adults, too, as I’ve heard some well-educated adults propagating common misconceptions …
Performance of AstroTrac TT320X-AG
It’s been a busy year. I bought this at NEAF back in April and have only just now been able to get out and give it a spin. The new feature, of course, is the autoguiding. With the original TT320, the specifications state a periodic error limit of 5 arcseconds per 5 minutes. As it …
Happy June Solstice Day!
For those of you who missed it, yesterday marked the June solstice, the first day of summer. Of course, my children disagree about the “first day of summer” part since they know the first day of summer doesn’t really happen until after school is out and here in New York City, the last day of …
Estimating Risks
The April 24, 2010 issue of Science News has an interesting article entitled "Gambling on Experience" which reports on research into how we (people) guestimate risk in real life. I call it interesting both because it is an interesting social question, but also because of a recent dialogue about the topic of cell phones and …
