I had an interaction with my lab partner that I thought was weird today, but I'm having trouble parsing exactly how weird it was (if at all!) and if I should do anything about it. [more inside]
My ten-year old son wants to understand everything. He is a voracious reader and doesn't confine himself to kids books. He loves reading the newspaper (NYTimes, Boston Globe), fiction, and non-fiction books. He's old enough to really learn things by reading. Agatha Christie is fun, but he's ready for more than that. He's full of questions about society, politics, science, economics. I'd like to get him some books that will expand his mind, begin answering his questions, and show him how the world fits together.

I would like to know if this statement is scientifically correct, or if it's hyperbole, or if it's basically correct but requires qualification: "Most of the atoms that formed your infant body at birth are now dispersed, as your present atoms will be again, if you have the good fortune to live a few more years on this oxygen-rich planetary home."

I'm looking to diversify the Twitter feeds that I follow (out with sports, in with other subjects), so I'm looking for good Twitter feeds by people/publications in the humanities fields, popular science and/or the media. If you can add a bit about why a particular feed is worth following, so much the better. Thanks!
I've got the chance to run a fun, whimsical sort of D&D adventure for a friend of mine. Yay! She's a bit of a science/math geek, and very fond of The Phantom Tollbooth by Norton Juster. So I was trying to think of fun, whimsical science and math jokes and references I could slip in to a sort of 'journey with sights along the way' in the style of TPT. [more inside]
I've enjoyed Tim Ferriss, Bulletproof Radio, Extreme Health Podcast and ReWild Yourself with Daniel Vitalis. What are some other good podcasts that address innovative/cutting edge health & science stuff? A little woo is OK.
I have a small black eyepiece from my dad's old chemistry set. Its purpose was to teach about isotopes by showing a visual example of radioactive decay. Any clues or knowledge of what the element inside is? Links to original documentation or similar sets? (Bonus question: This set is from the "our friend the atom" era, so, is it actually safe? I hope putting it up to my eye isn't like licking a radium covered paintbrush.) [more inside]
I'm looking for examples of well-designed scientific figures. As a materials scientist I've encountered many horrendous figures that are difficult to understand and read. I've read about collaborations between graphic design and physical science departments, which yield much more attractive and informative figures, but these examples are few and far between. I'm hoping to apply principles from good graphic design and data visualization to my own work. Are there any resources or websites where I can learn more about this?
I'm looking to redesign my personal research site and I'm thinking to use a blogging platform such as WordPress; however, I can't seem to find any good, clean and modern templates. In particular, I would like to add sections for my publications, recent news, scripts I have written, and my upcoming talks / presentations. Does anyone have suggestions for a robust platform and any themes that I could use for the site? Thanks!

My friends and I are having a disagreement. One friend says that if he hypothetically accumulated a "vial" full of black widow venom and injected it into himself that he would die instantly. I think that it would be horribly painful and not instant. Can anyone science me a real answer? No people or spiders will be harmed by this question.

I'm looking for examples of people who were considered geniuses in science, art, invention and other disciplines, but whose IQ scores were merely respectable, between 100 and 140. Richard Feynman, whose IQ was in the 120s, is a good example. But have there been others?
My cousin needs ideas for a joint class she'll be teaching for a college--she teaches literature, her teaching partner teaches science. (Which science, I don't know, but she says it's not relevant and he can touch on most scientific topics to the required degree.) They need suggestions of literature--poetry, short stories, novellas, or short novels--that she can have the class read, and then he can take them through the science of it. [more inside]
Spoilers for Kim Stanley Robinson's "Aurora" ahead. So, the story is like this: A multigenerational arkship is on it's way to Tau Ceti, they find their primary target for colonization hostile and discuss whether to move to another planet in the same system, live there in domes while terraforming it. One reason for not doing this is stated thusly: [more inside]

Lately I've been running across a lot of highly theoretical science and technology information that I don't understand. I would like to be able to recognize quackery and fringe science, as well as when technologists (especially programmers) are reinventing the wheel and claiming to revolutionize things, so I don't get steered in the wrong direction. I'm looking for heuristics. [more inside]

We are working on simple machine language in computer science for data manipulation. All the other problems I have gotten through but this last one. Here is the problem: "Write a short program in machine language to perform requested activity. Assume the program is placed in memory starting at address 00- -If the value stored in memory location 44 is 00, then place the value 01 in memory location 46; otherwise, put the value FF in memory location 46." Lots of questions inside DX Working with very basic Op-code and Operand setups. [more inside]

I'm considering attending the Geological Society of America conference this October in Vancouver, BC. I'm an undergrad geology student, and a student member of GSA. I'm not making a presentation, receiving an award, or bringing a poster. Do people ever attend conferences like this for fun? Or would I end up feeling like it was a waste of time and money, attending a conference that really wasn't intended for people like me? [more inside]

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]
I hate bugs, and I have one that is in my space. Can the generous and awesome amateur (or professional) entomologists of MetaFilter help me identify it, and perhaps give me a general sense of how dangerous it might or might not be? [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]
Today, I was enthusing about a photograph from the surface of Mars, and a friend responded along the following lines: "I find it hard to get excited about it when there are so many starving people here on Earth. We should fix our own problems before exploring other planets." How could I have responded? [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?
If you had a multivariate equation whose output variable is mean surface temperature on earth, what would be the rough beta value for distance from the sun (in millions of miles or whatever)?

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. Details: [more inside]
I have an odd job interview coming up. I need advise on a children's book to read to a grown up audience and a two minute poem or "fun" monologue to recite.

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.
