I want to create a Rube Goldberg machine (or something like it) with my students. I am not the best at teaching hands-on stuff/doing experiments and things that involve design, so I am looking for help and suggestions. [more inside]
I'm looking for links to pithy and readily engaging videos and/or infographics that present positive, optimistic, even inspiring, pro-science perspectives on any topic or area of controversy in which otherwise intelligent, well-meaning people might find themselves unwittingly supporting unscientific, pseudo-scientific, anti-scientific or technophobic viewpoints -- e.g. defenses of GMOs, vaccines, and "conventional" medicine, and educating against the naturalism fallacy and scare-mongering against "artificial chemicals," and psychiatric medication, etc. [more inside]
I'm curious to learn about human decomposition rates and wanted know: how long would it take for a human child's skeleton vs. a human adult's skeleton to dissolve in acid peaty soil? What about in soil us humans interact with everyday? (i.e. public park soil, garden soil) Thank you! Also, if anyone knows the answer, if you could please explain to me where/how you got the information :)

I again have time to consume books like a cookie-monster. I've avoided lists of classics-by-genera because I tend to like only 5% of what's on them. It's not that I specifically like reading dystopias or sci-fi - I liked the Poisonwood Bible for instance, as much if not more than Lord of the Rings. In addition to book recommendations, it would also be useful if, given the books listed below, you have any ideas for other trends that could help me search out books myself. Your advice is much appreciated! :) [more inside]

I am interested in articles that try to analyze and explain the conflict between the hard and soft sciences. In my casual web surfing I have come across e.g. highly-trained scientists who yet express a deep disdain for fields as open-ended and far-ranging as sociology, feminism, queer theory, postmodernism, and so on, sometimes even economics, psychology. I find such attitudes hard to comprehend, and even disturbing since my educational background is in the applied sciences. Which are the important works that have been done to better understand this ongoing social/intellectual gap, and that are presented in a readable manner for a non-expert?
Following on from the recent question on scientific personal development books, are there any scientific writings on productivity systems? I am aware of systems like GTD, and find parts of these useful, but they also seem to be "this worked for me" rather than based on significant empirical research.
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?
I am graduating within the next year. I will have my PhD in Pharmacology - 4 first author publications, 1 patent. Several presentations at national conferences in my field. I also have an MS in Biochemistry and a BS in Math. 1 year of experience working as a research specialist in academia. Various extra curricular activities that demonstrate leadership. I want to make 100k a year or more. I want to do this reasonably quickly (within the next 4 years). I do not want to go back to any schooling of any type. What options are available for me?
Please help a generalist brainstorm on what to do for a living. I'm finishing up a PhD in the physical sciences, and I love art and design. I'm happiest if I can constantly learn new subjects and if I can make things every day. How do I bring the parts of science and the parts of art that I love into the working world? [more inside]
Do you use Hermes perfumes? Do you like them? Can you explain them to me? I'm not a typical perfume wearer. I recently tried the Hermes fragrance Un Jardin Sur Le Toit at a friend's house and I really liked it. Then I started googling and found myself in a world of top notes, drydowns, accords, and other things where I don't even know what the words mean, much less how to understand them. Can you help me?

I'm in the earliest possible stages of building a web interface that will make it easy to display, graph, download, summarize, and interact with a wide variety of data. If you use scientific data from the internet, what are some of the websites you've encountered that make using data the easiest, most intuitive, and give you the best control? Also, what are some must-have features for you, and some of the best and worst design decisions the site builders have made? [more inside]
I need help finding a Christmas gift for my dad. I'm looking for: - Something that requires occasional hands on -- a project, but not a full-time project - 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 More...

Another gift-question, but I didn't find anything in the archives that's exactly applicable, so here goes: I'm looking for a Christmas gift for my 11-year-old cousin. He's pretty into science and math, and according to my aunt, already has tons of toys/games/kits. So it seems like she would prefer for him not to get another one of those, but her only other suggestion was to give him "coupons" to play card/board games with me. I'd be happy to do that except frankly I'm not sure he'd actually appreciate it - fwiw we rarely see each other, and I'm ten years older and female. I'm thinking a good book might be nice, but I don't know exactly what he's already read and liked, other than the typical series like Harry Potter, Percy Jackson, Diary of a Wimpy Kid etc. Any suggestions - either lesser-known books or other options I might not have thought of? My max price range is probably $25-30 but I can be a little flexible.
I'm in a Ph. D. program in Biophysics. I'm getting paid to be here. I've joined a lab and finished the classes, but I still have at least 2 and a half long years of research to go. I don't care for my project, I don't care for the town I'm in, and I don't even know if I care about science anymore. Finally someone noticed and I've been told I need to step up my game.

We have a spare room that we're turning into an Arts & Science room for the kids (13 year old girl and 8 year old boy). It's in a walk-out basement with a painted concrete floor and a window. We have some ideas but little knowledge in how to setup a room for them to create and explore. We have a cheap beginner's chemistry set, some art and craft supplies, and...that's about it. What ideas can we implement with the little expertise and money we have? [more inside]
You know how you can just remember a few details about some subject from your youth, and it's going to bother you until you can reveal the full scope of that memory? Yeah, I'm right there. I'm looking for a series of books. They were in the SF/F section in the 1980s. They were probably popular because their covers resembled Frazetta prints, and they tended to be really violent (i.e. jumping on the popularity of Conan). [more inside]

I have a large road case (2.5 / 2.5 / 3 feet) that I need to weigh. It is too big to fit on one scale. Would it work to place one scale under each of the 4 wheels and average the 4 weight readings? My physics-fu is not strong enough to figure this one out on my own. Help!
This Halloween I did some Halloween candy science experiments with my nieces and nephew. One of the experiments we didn't get to do (but soon will) is: Pouring Pop Rocks into a bottle of pop will make all that pent-up carbon dioxide escape but not fizz over. If you put the rocks into a balloon, then fit the balloon over the bottle's mouth and let the rocks fall in, it inflates the balloon with carbon dioxide. But what can I do with a balloon full of carbon dioxide? ...Is it a stupid idea to inhale it to see if I get a funny voice? [more inside]
Researching the human heart for an essay. The real heart. not the metaphorical one. I'm having trouble finding interesting articles online that go beyond 10 FACTS ABOUT THE HEART-type-things that get repetitive. I have already done a good bit of research into transplant history and fetal heart development, and I have a story about NASA growing cardiac cells in a bioreactor. But I still need more! Can you either tell me interesting true stuff or link me to it?
What are some contributions that Canadians have made to meteorology as a science? I'm looking for technologies, theories, whatever you can come up with. Even Canadians that were involved in the development of something to do with a technology or meteorological finding. I've spent most of my evening on Google with little success, yet I'm required to teach this to my students.

I recently saw a great animated piece expressing exasperation (that I share) with the anti-vaccine, pro-feelgood-pseudoscience crowd. It was from Australia or New Zealand (maybe somewhere in the UK?), it rhymed, it was clever and stylized in a way I want to reference to an artist friend. Ringing any bells for anyone, or have the vaccines rotted your brains, too?

This seems like it ought to be a simple question but I'm not finding the answer myself. Someone here must already know. I would like to buy sheets of printable adhesive labels suitable for sticking on 1.5ml/2.0ml microcentrifuge tubes. Ideally I would like both dots for the caps and little rectangles for the sides. They don't need to be able to stand up to particularly tough conditions, except that they shouldn't run if they get wet. Also, they should be cheap as I am a grad student and would be buying them out of my own pocket. I am just sick of writing the same teeny tiny letters over and over and over again with an ultrafine Sharpie. Can somebody here point me to a product that I can buy that would suit my needs?

I graduated with a biochem PhD a month or so ago. As is common practice at my institution - my thesis advisor offered me a few months of additional funding to finish up some papers while I hunt for industry jobs. Formally, I now have a post-doc appointment and salary, but I'm not actually taking on any new projects or doing any new science, nor do I have funding to stay her for more than another month or two. How should this look on my resume? I'm only applying to industry positions, not to academic positions or proper post-docs. [more inside]
Imagine you're allowed to give a nobel prize for five of the most seminal books of the past 50-60 years in whatever field you're interested and/or invested in. What would they be? The Nobel is usually given out to applied research and application and theory is eschewed. In this case you can give it to theoretical works as well. [more inside]

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. :[
Most machines are very predictable when in motion- their movement can be graphed in terms of speed, acceleration and jerk quite easily. Generally, the graph flattens out when you get to jerk. Can the same be done with humans? Or are our movements chaotic at a fundamental level? I know that ultimately we exert motion through force (=ma) but is it possible for us to increase the rate at which we increase the rate of force, and even increase the rate of that? Would we be able to register anything on the graph of m/s5? [more inside]
