Looking for stories/novelllas/novels about civilizations which have survived the "Big Bounce
" and persisted into the next universe. Is there any such thing?
I'm looking for high-resolution (full-color or gray-scale), public domain archives of landscape photography (specifically of terrains and mountains). [more inside]
I am interested in academic texts that discuss the ouroboros - the snake that eats its own tail. [more inside]
On a car trip yesterday my kid posed a hypothetical question. I was blown away, and I have no idea how to answer it. This is what she said.
"So light takes 90 minutes to go from Saturn to Earth. What if, instead of shining a light on Saturn, you had a long metal chain that stretched from Saturn to Earth. A person on Saturn pulls on the chain. How long would it take the person on Earth to feel that pull?" [more inside]
I'm trying to create a 3D model of a six-sided area of my garden. I know the lengths of each side. Is it possible to work out the exact angle of each corner?
Here's a link to a rough picture
- note that the labels are correct but the sides and angles aren't to scale. [more inside]
What are good layman-level books and articles on how the brain interprets narratives (books, television, or any other form of story)? [more inside]
I ran into some issues of "Scientific American, dated February 23rd, November 30th
1878 and a third February 1st, 1879, all in good shape. I also have one copy of "The Contemporary Review" dated November of 1879, in OK shape. I am curious as to whether they have any collector's value at this point. I have no idea how I came to own them, as these were dated before my father was born.
I'm looking for graphs and charts that show how many earth quakes of various intensities have happened in Texas over the last ten or more years. [more inside]
Recently, when flying over islands, I've noticed that the waves on the seashore appear to be motionless from cruising altitude. That is, you can see the white foam on the beach but it seems to be frozen in place and not ebbing/returning. Is there a name for this visual effect?
While I was visiting NYC with a friend, we found this weird naked-lime-looking
plant outside of a bodega. [more inside]
Can I bring California bay laurel branches to Arizona without potentially causing an ecological problem? [more inside]
Will soldering heat ruin an 18650 cell? [more inside]
I'd really really REALLY love to see the lights tonight and I'm willing to drive a couple hours to get there. I live in Magnolia in Seattle. Where do I go? [more inside]
I'm working on some graphics for an upcoming presentation, and need a way to display some scientific data(scatter plots and bar graphs mostly). What is the next step beyond excel? [more inside]
Is it going to be possible to see the northern lights in Minneapolis tonight? Will it be similar to a meteor shower, where one needs to get pretty far from the glow of the city lights to enjoy the show? Any tips/suggestions for how to make the best of it, or suggestions of particularly good spots from which to see it?
I expect this will turn out to be something akin to a lump of interesting concrete, but please take a gander at this object from a beach near Port Townsend, Washington, and tell me what you think it might be. [more inside]
I've got a bunch of curves that (I hope) show some common profile over time, although they maybe scaled versions of each other: at any index along in the curve >1, the next point is conditional on all (or some) of the previous.
See this greatly simplified example

Do not read this question if you do not like spiders. However, if you do like spiders, perhaps you can help me manager a guest in our garden. [more inside]
How do dams hurt rivers, exactly? Is that damage built in – that is, are there ways to mitigate it? On the other hand, do a few million people deserve electricity?
Looking for reasoned arguments. Caveat: solar power is reasonable, but I don't see it replacing the Aswan dam in the next few generations.
Taken in Joshua Tree National Park in October. The seed pod
is about 3/4" in diameter.
