I’m heading to the Milwaukee airport tomorrow, but my flight isn’t till the evening. Somewhere I read about a spot by Lake Michigan that was a good place to see migrating birds. Now I can’t find that article. Is this even the right time of year? If so, where should I go? posted by Hoenikker at 2:31 PM - 5 answers
Is there a book, article, or any other source that does something like run through the standard set of pathological results obtained from Axiom of Choice and discusses what happens to each if we restrict ourselves to Countable Choice? posted by PMdixon at 8:14 PM - 4 answers
If I tie a 10N weight to a balloon and fill the balloon with helium so that the weight is lifted 100m into the air, then 1kJ of work has been done. Who did that work, and when? Who lost energy? posted by Galaxor Nebulon at 7:09 AM - 34 answers
We're flying with our 2.5-year old and would like to find a nature documentary or TV show for her to watch on our iPad. She doesn't watch much TV, so this is a Big Treat that will hopefully distract her for at least some of the flight. The catch: we're not ready to deal with death yet, so I'd like something without predation/disease/starvation/etc. For simplicity's sake, I'd prefer something available on iTunes, but am willing to look other places, as well. We'd also prefer to avoid mass market characters (Elmo, Mickey Mouse, etc.). Any good suggestions? posted by griseus at 11:32 AM - 34 answers
A feral parrot (technically, a rose-ringed parakeet (Psittacula krameri), has started visiting the plumeria tree outside my front door this week. My housemate and I used to wish that some of the wild parrots that have been naturalized in Hawai`i would come and move into our yard. Now that one has, how do we seduce it to stay?
We live in the city, so any regular bird feed would be devoured in seconds by doves and pigeons.
We have a couple trees in the yard (pomegranate, palms, mango, plumeria, some Asian citrus thing), so there's nice habitat already. posted by kanewai at 3:22 PM - 4 answers
Why do we have order of operations rules in arithmetic instead of just strictly evaluating expressions from left to right (possibly with parenthesis for grouping if we really wanted to change the order)? posted by Reverend John at 11:49 AM - 9 answers
I'm considering renting an apartment with an induction stovetop. I had not been familiar with induction cooking, and in Googling it came across some sites that express concerns about the potential effects of electromagnetic fields generated by induction cooking (example: Swiss Federal Office of Public Health). I would like some more informed opinion on this subject (not "I have one and I'm fine"), specifically on the potential for harm and possible effects, either in linked readings elsewhere or from knowledgeable members of the community. Thanks in advance. posted by John Raskolnikov Gilson at 11:37 PM - 9 answers
It seems to be common knowledge that elderly people, or others who are subject to more falls, will sustain more fractures than the rest of the population, and will have increased morbidity as a result. What I am looking for is an authoritative journal article (abstract or title is fine), preferably from an orthopaedic publication, stating the above.

Some years ago, I read about a study on workplace productivity, set up to test the effect of a new office layout (or perhaps some other physical feature of work environment). They changed to the new layout, and productivity jumped up. Over the following months, however, productivity tailed off to the original levels. So they changed the layout back to the original one. Again, productivity spiked suddenly and gradually declined back to the baseline. It was concluded that, whatever the relative merits of different office arrangements, the very act of making a change causes a temporary productivity increase. Does anyone know where I can find this study? [more inside] posted by pont at 10:20 AM - 3 answers
Not that I'm writing a Walking Dead fan fiction or anything, but if I was I have a few hypothetical questions about water towers, wells and human waste disposal during an extended power outage. [more inside] posted by Oriole Adams at 12:03 PM - 10 answers
I break open both vitamin E and A capsules for use on my skin sometimes. I notice E is very thick while A is light and runny. Is this a property of the molecules, or are they just in a different carrier? I don't know organic chemistry, so I can only speculate. posted by Listener at 6:18 PM - 7 answers

It's the emotional/moral brain/limbic system I'm ultimately interested in and how it affects behaviour and potentially criminality or a disregard for the rights of others, when 'malfunctioning'.
I am reading the anatomy of violence (Adrian Raine) but finding some of it hard work. I'm interested in the anatomy and functioning. Thanks posted by tanktop at 9:55 AM - 6 answers
Can anyone tell me where the world's oldest forest might be? I'm wondering what place on Earth may have escaped the glaciers, catastrophic flooding, giant meteor impacts, volcanos, etc.
I'm not interested in the world's oldest trees, or even the forest that's been least disturbed by human activity. I looking for the longest unbroken chain of terrestrial life. posted by bonobothegreat at 9:20 AM - 19 answers
