Kodachrome

You give us those nice bright colors You give us the greens of summers Makes you think all the world's a sunny day, oh yeah! I got a Nikon camera I love to take a photograph So Mama, don't take my Kodachrome away - Paul Simon Sometimes we love a moment so much that it hurts to think about it ending, so we cling to it. We long to capture our present and preserve it, keep it from changing – like taking a picture. Sometimes it isn’t love that makes us grasp at a moment, but the fear of what might come next. We crave fixity, when everything around us is in flux. Maybe I am alone in that need, but I don’t think so. Regardless of the reason, I think much suffering comes from clinging to what is known, what is familiar, to who we are at any given time. Life feels so much more manageable when we have planned out what will happen and prevented the unexpected, when we are safe. It doesn’t work that way, of course. Life is change. Nothing is guaranteed, nothing is static. Stuff happens. We become who we are and who we will be through a process of beginnings and endings. Facing that reality can be frightening, its no wonder we sometimes attempt to capture where we are under glass.

Sticker Shock

Back in the 1980's I learned that digital electronics always rapidly descend in price. Pretty much, if you bought a computer, disc player, or digital camera a month ago then the price would already be noticeably lower. But I recently was told (by Erich as he took the pictures here) that the camera he (and I) love to carry has increased in price since we bought them. I didn't believe him, so I looked it up at Pricegrabber.com and at Amazon. Amazon seems to show the real prices that the (lower) PriceGrabber links jump to. The exact camera that I bought for $160 from Amazon 7 months ago is now a whopping $358! Un-be-(expletive)-lievable. You may remember Erich and I raving about this little gem since he first bought his over a year ago. I shopped independently and at length to select the same camera. One odd feature of it is that it is available in a range of colors. I bought mine in Gold because it was the cheapest at the time, by $5. Now however, the price is about $180 in blue or brown, up to $358 in ... Gold! Apparently, this camera is now a hot item. Possibly one reason besides those we've mentioned on this site is that hackers have been at work. One can download uncertified "patches" to make this camera do even more amazing things. See Turn Your Point-and-Shoot into a Super-Camera at LifeHacker.com I feel that this is but another sign of our living in Interesting Times.

More undocumented workers in my front yard

I spotted these guys today. I really admired the way they worked. I had to bring out a reading lamp to the front porch (during the daytime) to get a bright enough field to get a clear photo. I also liked the way the colors turned out here. There were hundreds of ants whisking their cargo from one side of the porch to the other. Nonstop. Unrelenting. Click on the photo for details. img_7257

Fun on the frontiers of astronomy

Want to watch/read an entertaining and inspiring three-part discussion covering the frontier of astronomy? All you need to do is follow this link to the article and videos at Discover Magazine. The participants include Saul Perlmutter, Debra Fischer, Mike Brown and Andrea Ghez, in a panel moderated by Discover's Phil Plait. It's lively, accessible and mind-blowing. Here are a few of my favorite quotes: [Debra Fischer]

We started out with a solar system where many planetesimals were forming, and that evolved into a system where all the stable niches are filled. To me that’s one of the most exciting discoveries in this field.

[Mike Brown]

[I]t’s the small objects that really matter. The small ones are little particles that sit in the outer solar system, and they’re gravitationally swept around by planets. The analogy I like is that these objects in the outer solar system are the blood splattered on the wall after some horrendous murder. I love this analogy—it’s disturbing, but I love it. As Debra just suggested, there might have been additional planets that used to be here in our solar system [but were ejected due to gravitational instability]. The bodies have all been removed.

[Andrea Ghez]

The question that I started off with was, I thought, very simple. It was just “Is there a massive black hole at the center of the Milky Way?” But one of the things I love about science is that you always end up with new questions. What happened with my research is that the stars we studied to prove that there was a black hole turned out to be very young. Young stars have absolutely no right to be next to a black hole because a black hole should shear them apart. We have no idea how these stars formed. So that’s one of the major questions we’re trying to address today: “How do baby stars form next to this completely inhospitable object?”
