Why Does The Mind Do Such Shoddy Detail Work Re: Dream Imagery?

In dreams, any sort of writing appears blurry/squiggly/unreadable. It seems apparent that we lack the cognitive bandwidth to fully populate such data-rich imagery on the fly, so we fudge (and our dream narration finds excuses for it). Other detail fudging occurs in dreams, as well. Might there be anything interesting to discover about cognitive power by testing the parameters of this shortfall, e.g. via lucid dreamers who can consciously evoke given imagery? Also: any speculation as to why the mind does such lousy CGI?

What's the best way to magnify an eclipse? With two viewers?

So the eclipse was amazing, and an acquaintance watched it with binoculars and managed to see a solar flare rise up and curve back into the sun at the last second of totality. That sounds amazing and so I want to see awesome(r) things in 2024. What good options do I have for looking at a magnified image of the corona during the totality? [more inside]

Is this a bed bug?

Is this a bed bug? Link to flickr album: It seems to match a lot of descriptions I've found online. Unfortunately I did squish it due to freaking out which apparently doesn't help with ID'ing.

What are these spherical nest looking things on power lines in Mexico?

Physical Experiments for Proving/Disproving Simulation Hypothesis

In the novel After On, there's the following phrase: "[a]lthough some people have proposed actual physical experiments to test the Simulation Hypothesis ... ", going on to say we don't have the technology to do it yet (to which the author muses 'by design?'). My Google searches aren't honed enough, and I'm getting too much chaff and not a clear answer. Assuming the proposal of the physical experiments was itself not fictional, can you point me towards a description of the proposed physical experiments?

How real are described experiences to others?

Point me to some research about how well people can understand things that haven't happened to them directly. e.g. If you haven't experienced PMS, how well can you understand and empathize with someone going through PMS? "How well" is pretty hard to quantify, and I don't know what to Google for, so this may be fruitless, but I thought I'd take a shot.

Photographing people during the eclipse?

I won't be spending the eclipse snapping away instead of enjoying it, but I'd like to get a quick picture of our family. The eclipse photography guides seem to focus on the sun itself. I have an SLR and a couple of lenses to choose from. [more inside]

Chemistry Filter: How did this happen?

I bought my daughter a cheap rubber (?) ball at Michael's a while ago. Last night it ended up wedged up against our cabinets all night. This morning the lacquer seems to have become liquid where it was in contact with the ball. [more inside]

Can you help identify this large bug?

What is this bug? We are in Newfoundland. It doesn't seem to have antennas (antenni?). Hand for scale. My seven-year-old really wants to know...

Where to donate to fight climate change?

I'd like to make a donation to some international organization whose main focus is combating climate change. It's ok if they work on other environmental issues as well, but the thing I'm most concerned about is climate change and would like to see the majority of my money spent there. It also should be international, as opposed to US-centric. Does anybody know of some good ones?

A buttercup plant: Japanese library edition. Tell me more, please.

Record 1,000,000,000 (one billion) in OCLC's WorldCat is a plant in the buttercup family. The original entry in Chiba University repository is (both Japanese and English versions) mostly in Japanese, which unfortunately I don't speak. Struggling with Google Translate. Can you provide more information in English on this particular plant and/or catalog entry?

The (false) belief that climate change causes weather

Weather is local, climate change is global. The former cannot be attributed to the latter. This is what I've always believed because it's what I remember hearing climatologists say. Meanwhile, newspapers and news channels again and again attribute extreme weather to climate change. Either I'm wrong or they're wrong. [more inside]

Recommendations for books about 40 year old space probes

After the recent wonderful NYT article on the ageing scientists and engineers of the two Voyagers, still silently transmitting from outside the heliosphere ( the Voyagers, not the engineers), I wonder whether I could get some recommendations on literature about the probes' journey and discoveries.
