Here are a few facts about this old SF story whose author I can no longer recall.
1. It was written by a giant of mid-century SF whose name I can no longer recall. Not Sheckley, not Asimov. I thought it might be Damon Knight, but I can't find it in his work.
2. It's a story about a man who travels to the future as part of a gigantic relief effort to assist future men who are burying themselves in the earth. [more inside]

There's this science fiction story I can recall reading in at least one anthology, if not multiples. It is told from the perspective of a young mother who is going crazy dealing with her kid(s). The writing is very stark and bleak, but it's a fun story nonetheless. I am fairly certain the author was a woman. I believe it's from the late 60s or early to mid 1970s. [more inside]

need some pointers as to research strategies/leads to find out about the state of the art knowledge about the moon in 1878, with particular reference to things arising in or popular in the French scientific community. First thoughts are Times digital archive and to look for an encyclopaedia of similar date. Any leads appreciated.

I have a large tupperware full of a crystalline white powder. It could be sugar, or it could be xylitol. How can I tell?
So far I've found two possible ways: burn it and record the energy per gram; feed it to dogs. I would prefer not to do the second, as xylitol kills dogs. I'm open to the first, if someone wants to link me to a good experimental method for such. But I'd really love a third way.

I read a while ago a quote from Oppenheimer that eloquently expressed the idea that once a scientist gets in his or her head the idea that a result is achievable, he or she will not be stopped until that result is achieved. He referred to the scientist, though the sense in which he meant the term might better map to what many consider an engineer. [more inside]

I'm under the impression that factory farming is insane and detrimental to our continuing existence as a species. However, it's difficult to find resources that further explore the environmental impact without the Peter Singer-type ethical concerns of animal welfare, which is appreciated but sometimes lacks a certain scientific rigor.
Are there good, go-to resources that explore the environmental impact of factory farming that refrain from diversions into animal rights?

So, I recently got selected to do undergraduate physics research this summer. Great! Awesome! Yay me!
However, my research advisor has asked me to use something called IDL to analyze tomographic images of compounds and turn them into 3D images. This is good news, because IDL is used a lot by astronomers to analyze astronomical data, and I want to continue my education in astronomy. But, I've never used IDL ever before. I'm not even sure exactly what it is (a programming language?).
My question is this: how do I get up to speed so that I can hit the ground running with my research?
Difficulty: Research begins in two weeks.

Please help me find a mystery book from my childhood. I am stumped.
It would have been in the mid 70s, probably between 1974-77. I think it was science/nature-related book that may have been one of a series. What I remember is a hard-cover book, and on the back inside cover there was mounted a round plastic disk with an arrow inside, sort of like a compass. It was visible though holes in the pages and front cover. There were questions with multiple choices on each page, and you would close the book and knock on the cover a certain number of times to make the needle point to the correct answer on a corresponding page. That sounds crazy even as I type it, but if someone could find this book (or even corroborate my memory) I would be eternally grateful.

On late night tv earlier this month I saw a 50s or 60s educational documentary about bees that was made in affiliation with a christian college in America. And it was hilarious. The first half was sort of straight-forward science about how bees work, and then toward the end it takes this turn about how we should all follow the old testament which would make us happy and productive like bees. And now I can't remember the name of the film company (which was named after the college) which apparently did many such educational shorts in that time (either 50s or 60s I don't remember which). Does this ring any bells with anyone?

Hello, qualitative researchers! I'm doing a qualitative research project. i have a series of interview questions i wanted to ask some people. to make sure the questions were good, i asked them to my pre-test subject. the questions seemed clear and their responses seemed interesting.
but is there some more scientific way of saying (or deciding) "Yup, seems good."? I need to write in my thesis how i came to the conclusion that the pre-test was successful. I can see how this would be easy(or more precise) in quantitative research, but i don't have any numbers.
How do you do this? And how do you word it? Thank you!

Why don't we have HD video of Earth rotating in space? You know, relatively close-up, as if the Enterprise had just dropped out of warp and the planet was being majestically introduced to the cinema audience. An extended, multiple pass/rotation exposure, so that it could be watched by appreciative viewers wanting to get a bit of perspective/peace. I imagine I would sit and gaze at this for extended periods. What are the technical limitations which have prevented this?

- Something a little science-projecty and geeky, but that does not involve a computer (he's 72 and not terribly computer literate; he does have an iPad, though)
- Something that has a definable end result
- Something he can attend to while my folks spend three months in their RV this winter
- Most likely something plant-related

There is a concept I remember reading about but can't remember the name of, and none of my flailing Google searches are coming up with anything. Basically it's the concept of... repeatability? Our assumption that the laws of physics remain constant? The notion that if something occurs once, that given the same circumstances it will happen again, eg every time you add vinegar to baking soda it will foam up and after repeating things enough times we can assume that it will always happen- it won't suddenly burst into flames or turn into a radio or whatever. I remember reading that this assumption is both what science is based on and something we can never know for sure, since all it takes is one instance of flammable baking soda and vinegar to disprove it and maybe that'll happen tomorrow. I'm also not 100% sure this is a real scientific concept and not something I read in science fiction. :[

We've had PG&E SmartMeters installed at our building for awhile, and our landlord is very concerned about the health risks and surveillance risks he believes they pose. He's sent us a bunch of "literature" to read and it all reads like wackadoodle conspiracy theories with no basis in science, as does everything else I've found online. As easy as it is to just roll my eyes and dismiss his concerns, I feel like I should make a good faith attempt to discover if there's really anything to be concerned about. Are there any good, reality-based reasons to be anti-SmartMeter? Any science-based studies from reliable sources on their safety? Any well-thought-out articles on the subject that don't include the phrases "molecular earthquakes" or "like hundreds of cell phones being on at the same time"? Help a skeptic out!

I'm trying to remember the name and author fo a sci-fi novel that predicted the idea of Google glasses and their impact on society. I can clearly remember one of the characters, a youung person, complaining that all these old people had these glasses that recorded everything that happened around them and could send that data directly to the police. It was kind of an Orwellian Big Brother feel to society. You were always being watched, recorded, reported, etc. I was reminded again about this after reading an article on NPR about the first police arrest recorded on Google Glass

The majority of info about alum crystals for personal hygiene tends to be on "natural living" web sites and the like, so my main question is: is there any actual scientific study either way as to the safety of such a thing being rubbed on your face on a regular basis?
