• Antarctic ice loss unstoppable?

    Everyone seems to be hand wringing about the west Antarctic ice shelf sliding into the ocean, but nobody seems to be working on how to improve the situation. Given that the ice sheet is detaching from the sea bottom, because warmer ocean water is convecting under it, why couldn't we hang a curtain from sea floor to almost the surface, weighted... show more
    Everyone seems to be hand wringing about the west Antarctic ice shelf sliding into the ocean, but nobody seems to be working on how to improve the situation. Given that the ice sheet is detaching from the sea bottom, because warmer ocean water is convecting under it, why couldn't we hang a curtain from sea floor to almost the surface, weighted at the bottom and floated at the top, like large fishing nets, but with less holes. Wouldn't this interfere with the water convection and help the ice sheet reconnect to the sea bottom? I know it would be expensive, but so is relocating dozens of coastal cities and most of the world's human population to higher ground. This might give us a few extra centuries to get greenhouse gases under control.

  • Weird borax crystallization?

    In an attempt to purify 20 Muleteam Borax powder, I dissolved about 1.5 cup into about a quart of hot distilled water. Then I covered the jar let it slowly cool, in a styrofoam box. Very little material recrystallized at the bottom, so I put it in the refrigerator to force more crystallization. Weird effect #1 But a day later, there was only a... show more
    In an attempt to purify 20 Muleteam Borax powder, I dissolved about 1.5 cup into about a quart of hot distilled water. Then I covered the jar let it slowly cool, in a styrofoam box. Very little material recrystallized at the bottom, so I put it in the refrigerator to force more crystallization. Weird effect #1 But a day later, there was only a slight increase in crystal mass, but with tiny seed crystals forming all over the sides of the jar. So I left it there for a week, and the seed crystals just grew, very slowly. And they were quite well formed and clear. Weird effect #2. I poured about 1/4 cup of the solution off (because the jar was very full and easy to spill). The next morning, there was a large increase in crystal mass, and the neat crystals were covered in a lot of chaotic crystal growth. Weird effect #3. Two days later, the jar cracked and most of the remaining solution drained. Where the glass cracked, there is a definite protrusion of the side of the glass from the bottom. I can't say whether the side is pushed out, or the bottom is pulled in. This is a canning jar, so it should be well annealed and resistant to thermal shock. I can guess that supersaturation was involved in weird effect one and two, but what effect broke the jar? Thanks.

  • This one was a lulu?

    I was a team member on a paleological expedition, looking for fossils or historical remains or something. After I found a few nice fossils of small work like things, I happened to nick my arm and noticed that beneath my tanned skin was something much darker. I started peeling back my skin to find completely tattooed skin beneath, and after peeling... show more
    I was a team member on a paleological expedition, looking for fossils or historical remains or something. After I found a few nice fossils of small work like things, I happened to nick my arm and noticed that beneath my tanned skin was something much darker. I started peeling back my skin to find completely tattooed skin beneath, and after peeling a large part of my body, it turned out that inside me was the remains of some person who had died, nearby. It was as if all that was me was the thin layer of skin peeling off. We found some living relative and learned much of the life story of the person in me and, by the end of the dream, I was gone (peeled off), and they were living their life, again. While I was peeling myself away, I knew that it was destroying me, but I wanted to learn who was under my skin. Have at it. -- Regards, John Popelish

  • Is the color of dog's retina a characteristic of the breed?

    I notice that when I take a flash picture of different dogs, their lenses looks different colors, depending on the dog. For example, I have pictures where a pug's eyes reflect an electric blue, a beagle reflects green and a mix of beagle, basset and blue heeler reflects a dark orange-red. Is the reflected color of a dogs retina (what we call... show more

Is the reflected color of a dogs retina (what we call red-eye in human photos) information about what breed they are or contain, or is it completely individual? -- Regards, John Popelish

  • Comeuppance ? I haven't heard that word in years.?

    This morning I dreamed that I was a camper in a summer camp with a very disliked camp counselor. Somehow, he got stranded in camp with no food and had to survive for a few days by eating crackers he made of shredded newspapers, flour and salt. When everyone got back to camp and rescued him, they all referred to his paper mache crackers as... show more
    This morning I dreamed that I was a camper in a summer camp with a very disliked camp counselor. Somehow, he got stranded in camp with no food and had to survive for a few days by eating crackers he made of shredded newspapers, flour and salt. When everyone got back to camp and rescued him, they all referred to his paper mache crackers as comeuppance, as if this were the normal name for this food. "All he had to eat while we were gone was comeuppance." I laughed so hard about this name, that I woke myself up. What do you think? I had to look the word up, to make sure I knew what it really means. I'm 61 years old, by the way. -- Regards, John Popelish

  • Is there any music that your dog likes?

    My new beagle, basset hound, blue heeler mix, 7 week old female seems to be getting attached to a nightly playing of an album of Rag Time music (Music of Scott Joplin played by James Levine).

    My new beagle, basset hound, blue heeler mix, 7 week old female seems to be getting attached to a nightly playing of an album of Rag Time music (Music of Scott Joplin played by James Levine). The last few nights, she gets restless before bed time, but settles right down for an hour or so of listening, half asleep and stops being concerned who is in the room with her. I'm trying to figure out if this is strange or common. I wonder how this nightly pastime will affect her development. -- Regards, John Popelish
