joeblast Posted March 3, 2010 Interesting - the ground is still shaking down in Chile, and some scientists say it will continue to do so to an extent for months to come. This is an 88 second exposure taken on feb 28th, you can see the "star trails" are a little wobbly! Â Â Share this post Link to post Share on other sites
Trunk Posted March 3, 2010 This is an 88 second exposure taken on feb 28th, you can see the "star trails" are a little wobbly! Â Did you take that shot? Impressive shot. If so, I assume you're using a digital SLR? What a dream... I'm having fun with my little point & shoot Canon digital. Good fun. But the possibilities open way up with the SLRs.

joeblast Posted March 4, 2010 nah, I actually need to get my lens cleaned, I have a big speck of dust screwing up my pictures! that was from the spaceweather.com page, someone sent it in there, figured "the ground shaking" would have given it away - it was taken down in chile!

joeblast Posted March 31, 2010 Â for us northern hemisphere people... Â its supposed to be nice in the northeast in the next bunch of days, I'd love to get a chance to see mercury - I've tried a couple times but never have been able to see it, its pretty elusive, especially when you live in a hilly area!

soaring crane Posted April 5, 2010 Pretty cat. Very well fed BTW. Hehehe.  Peace & Love!    lol, good observation, MB. She came from a farm up the street, started hanging around our house looking for a quiet place to have her babies, being pregnant and all. At that time, she was probably about a quarter the cat she is now - completely emaciated, missing a couple teeth, with all sorts of diseases and parasites, maybe four years old, she'd led a life on the farm that I wouldn't wish on a dog.  We took her in. She's incredibly intelligent and personable. She really is like a dog in many respects. AND she doesn't plan on ever going back to the farm again. She's made herself comfortable here and we let her enjoy herself. She gets fat over the winter, but as soon as the weather turns warm, she'll be outside most of the time and her weight will come down to normal ranges.  She's also a mouse-terror. It's happened more than once that she was sitting on the window sill in the living room and suddenly goes into a panic to get outside. She runs down the stairs and comes back up with a mouse in like a minute. Meaning, she spots a mouse moving out on the lawn from the 2nd floor window and runs down to the exact spot and snatches it like it was a snack bar or something. When she first "moved in" and was still mostly outdoors, she was bringing home up to twenty mice every day. All for me, of course. Yum   Share this post Link to post Share on other sites
Marblehead Posted April 5, 2010 Hehehe. Thanks for sharing that. Both my cats were origianlly someone else's but they couldn't keep them. One boy, one girl. Both fixed. The boy is getting pretty old but he was one heck of a mouser and rater in his younger days. Brought me presents all the time from my neighbors' houses. Â Yes, you didn't mention if your cat was male or female but I know what you mean about fattening up over winter. Â I am sure you are enjoying having her around. The area of where the picture was taken looks like a wonder place for an outdoors cat. Â Peace & Love! Share this post Link to post Share on other sites

joeblast Posted April 23, 2010 From The Reference Frame  If you take a photograph of plants in the infrared, they appear extremely bright, especially the leaves:  In fact, as Sean Carroll correctly explains in The Red Edge, this behavior of the plants on the photographs can be reduced to their spectrum:  Note that the plants absorb lots of the visible light - the left portion of the picture (except for the chlorophyll bump at 500 nm) - but they instantly begin to reflect the infrared light. The huge jump between the visible and infrared spectrum is known as the red edge. A similarly striking signature has been proposed as a sign of life on other planets. Is that sensible?  First, we should understand why the plants behave in this way. This question can be approached in two basic ways: by looking for a microscopic explanation, and by finding the purpose or the evolutionary survival advantage that the plants gain by this behavior.  ..... *snip* .....  The abundance of the visible light is also why our eyes are optimized for the visible band. They're not "canonically" or "perfectly" optimized - after all, some other mammals can only see two independent colors, not three, and the precise sensitive bands may be shifted - but it is a qualitative argument why it is more likely for organisms to have eyes that are sensitive to the electromagnetic radiation that is easily available rather than the "rare" forms of light. You simply don't need too sensitive gadgets to "see" if there's enough light.  So the plants' processes are optimized for particular frequencies that sit inside the bands where there's enough light so that they don't have trouble to find the light. Again, different plants use different frequencies for photosynthesis: much like in the case of the mammals' eyes, these technical details are not universal.
