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]

One has a green cover, one has a blue cover, but they both have pictures on the front.

I work at a Museum and we are about to roll out a new staffing model for our part time staff. Essentially a "career ladder", the program will have four stages of progression starting with general skills (everyone in this stage can float around the Museum providing customer service, essentially). The three subsequent stages add increased specialization, training and skills (employees in stage 4 can lead teach programs like camp, for example). We have a pretty young staff, and are generally a hands-on STEAM (science technology engineering art and math) focused institution. We're looking for creative names for the stages that are descriptive without being too silly. Any thoughts? [more inside]

I'm a research scientist and I sometimes give presentations. Presentations are unique because, while they aren't the most important part of my work, there is a built-in deadline. I can only work on them until the presentation time, and then I won't get another chance to redo that particular presentation. Most other things I can work on until they are done in the order of what is most important. But giving a good presentation is still pretty important. So when I have a presentation coming up it is hard to decide what to work on first. If I work mainly on the presentation then I feel like I am postponing my important regular research, which isn't great. If I work mainly on the research, then I feel like I am resigning myself to giving a more mediocre presentation, which isn't great either—it makes it less likely that people will understand the work and isn't good for my reputation generally. If I try to switch back and forth I lose concentration and energy due to the difficulty of context switching. Do you have suggestions for how to set priorities in this scenario or what has worked for you?

Please suggest material that has helped you become a better researcher. Which resources have helped you weed out the pseudoscience and poor quality information?

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!

Somewhere in the last two to five years, I read about a study where a group of women (I believe the women were Asian, possibly Vietnamese or Thai) were given meals that were: (1) either beautifully and colorfully presented, or (2) pureed into a gray mush. The meals had exactly the same nutritional content, but the women receiving the colorful meal absorbed more nutrients.
But I can't find any articles or the study itself. I've been Googling up a storm and still nothin'. Anyone remember this, or articles about this? Help me please?

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
. Does anyone else remember this book or the author? Thanks in advance for the help.

When I was a kid, I was totally enamored of dinosaurs. I seem to have lost my affinity for them in the years since. I quit paying attention to developments in paleontology. Apparently there's been a lot that I missed, like that the dominant theory now is that modern birds are descended from a dinosaur species (I think?). And I hear velociraptors had feathers. So I need not just updates, but a good primer for adults because I've forgotten everything I used to know about them.
Can anyone recommend some good modern books or documentaries on dinosaurs to rekindle the flame of dino-love?

Dear MetaFilter, I am new to this forum and this is my first post, hi!
I am in a bit of a pickle about a work project, and hope that I may be able to get some help by some fellow sciencey people. The science forums are rarely read and badly out of date, or I would have posted at one of those.
I have a deadline for a miRNA PCR experiment, and I have already run the cDNA and PCR for the miRNA. All I have to do is run the miRNA on a gel.
We don't have acrylamide! And neither does our neighboring lab. We only have Agarose with which to make gels, which is only for large fragments, not small miRNA fragments of 20-40 bp.
As the percentage of agarose in the gel goes higher, the smaller the size of the base pairs are that can be measured. Could I increase this percentage enough to work for miRNA?
Out of respect for the community that doesn't like line returns, I have entered the specifics of this post in the Extended Explanation box, because to me, this post reads like a jumble of nonsense without some kind of organization. [more inside]

A friend of mine is designing a clinical trial to determine the comparative effectiveness of different methods of pain control during IUD insertion. The problem is, there isn’t a lot of existing literature on what women are actually being offered out in the real world, and what does exist is pretty low quality.
If you have an IUD, and if you were offered pain control measures during insertion, what were they? How effective those measures were isn't really relevant here, because that's what the trial is designed to figure out; I’m just trying to help her get a sense of what the current state of practice is so that the design of the study can be as robust and relevant as possible.

Where can I find a large poster / chart detailing all the geological epochs and periods? The chart produced by the Geological Society of America
is a good start, but it would be more useful if it was, say, annotated with important events ("Angiosperms evolved here! Gondwana separated here!"), and it it had maps of the positions of continents on it at various times. Has anyone seen anything like this? My searches for geology posters have mostly turned up pictures of mountains, or "Geology Rocks!" logos...
