Pulsars
September 23, 2009 at 7:59 am | In Physics, Uncategorized | Leave a CommentThe LIGO collaboration just pushed a new paper to the arXiv. In it, they describe the search, using the most recent long science run, for known sources of gravitational waves (spinning pulsars whose spin is being slowed as they radiate gravitational waves). They’ve now reached or exceeded the spin-down limit for a pulsar or two (gravitational waves don’t do all the slowing, especially in young pulsars) and have tens of them within less than an order of magnitude of their noise. Advanced LIGO should, indeed, pick them up if they hit their noise goals…. The next decade will be very exciting in gravitational wave physics.
LIGO’s taken another step toward doing what was once sensibly believed to be nearly impossible. Congratulations are absolutely due.

Yet another night of Steven. As usual, the movie was far from good, but the company was excellent. After largely killing a bottle of wine myself, I’m strangely uninebriated. I blame the potatoes.

Stars
April 3, 2009 at 11:17 pm | In Uncategorized | Leave a CommentThe clouds decided to take a field trip elsewhere tonight, so there are planets and stars about. Tomorrow’s a bit uncertain, but it’ll certainly dawn clear and cold. Whether we head for the Slot or merely the Sage’s haunt, we’ll have fun in the snow.
Miles tomorrow, many miles, near Davis. Here’s hoping they’re passably pleasant!

Gut says don’t. Weather gods say go, but they also predict another foot of snow for the weekend. Ski camping somewhere awesome is sounding very attractive.
Curiosity
March 12, 2009 at 8:47 am | In Uncategorized | 2 CommentsAfter some thought, it seems to me that the best reasons for undertaking an experiment are curiosity and necessity. Either there’s just something you’d really like to know, or somebody somewhere really needs to know something.
I’m still naive enough to believe that science isn’t about racing to a result, or about scooping a competitor. It’s about trying to learn something new. Like at the cutting edge of climbing, it’s about pushing the boat out as far as one possibly can. There’s no doubt in my mind that I’ll be personally better off if my experiment reaches its goals before similar ones can, but getting there first cannot be the underlying motivation for my work. Reaching more sensitive results more efficiently can. I believe there’s a fundamental distinction.
I will not see my friends as enemies.
