The aforementioned shrimp has the advantage of using its "gun" underwater which is a pretty decent coolant. The woodpecker manages to hit ~1000g's of force* with its head/beak and evolved a tongue that extends the length of its body to feel around for buggy goodness but also retracts to make a shock absorber around its brain case. Given enough time you get some really weird poo poo is what I mean. Not sure about Gatling guns though since natural selection has yet to produce the wheel. * http://www.ncbi.nlm.nih.gov/pubmed/454236 posted:High-speed cinematograph films of a drilling woodpecker were examined by direct visual inspection and by a microdensitometer and computer-imaging technique. These showed (1) that the drilling trajectory is essentially linear, with very little, if any, rotation of the head; (2) that there is minimal movement after impact; (3) that the impact velocity is of the order of 600 to 700 cm/s; and (4) that the impact deceleration is of the order of 1,000 g. Dynamic and morphologic findings in the woodpecker may be highly relevant to the prevention of concussion and brain injury in man. Taken in the context of modern packaging technology and other animal and mathematical modelling research, they suggest that brain injury preventive systems could be greatly improved over those now in common use.

Flagella are pretty weird when you think about it. They're basically whip-like propellers hooked up to a biological motor and rotate independently of the body... all in a single cell.

So heat will be your limiting factor in the evolution of zebra gatling guns, not conductivity, because as Xenoborg said: we already conduct electric signals through our nerves. There are animals that produce materials that can withstand extremely high impact forces and the Mythbusters built a cannon out of a tree trunk once and were able to fire a shot out of it. There's probably a high speed but low temperature reaction like the sort used in airbags that could feasibly occur within a suitably equipped cavity in a living organism without destroying it, so an organic gun, while it wouldn't be at all comparable to mechanical guns, is not completely impossible. The real reason a zebra can't evolve a Gatling gun is that life as we know it cannot produce joints with total freedom of rotation.

The article originally quoted actually mentions that the pearl moth caterpillar and a Calfornian salamander both roll themselves up to move quickly downhill when pursued by predators (the caterpillar can do it on a flat surface), which are very wheel-like traits. Evolution is crazy.

Goddamn posted:I've got this weird memory of an old commercial(?) on... Maybe PBS or something? Where they were pitting a book dictionary versus a computer dictionary. Something about where you would find a word faster. Except the computer sequence was this ridiculous, dragged out thing of slowly booting it up, putting a CD in, typing really slowly and waiting for the program to load, while some other kid just found the word in the book so the book was declared the "winner". It was pretty ridiculous but I can't seem to find it, does anybody know what I'm talking about? (Or if there's some thread for these) You're not crazy, I remember this. It had a voice over saying, "Let's see which way is faster!" or something while one kid grabs a dictionary and another goes to the computer. I agree it was ridiculous because the computer was off so that kid had to turn it on first, put in the CD, load the program, type in their search, and wait for a result. I can't remember for sure, but PBS is probably right, I used to watch it a lot.

Brother Jonathan posted:So "acting up" is the general term, and "acting out" is a specific kind of "acting up" by someone? That makes sense. "Acting out" is carrying out a thought, be it disruptive (expressing feelings of anger in the form of arson or shooting sprees) or not (working through some mental/emotional issues or blocks).

One of the kids brought home fleas, and now every room is covered in the little bastards. How do I get rid of them today, like right now. They're all over and I'm miserable, We don't have carpets so I'm not really sure where their eggs would even be.

About passwords! If a site allows, say, 20 character mixed case alphanumeric passwords, but I only do, say, five lowercase letters that don't form a word, could someone who has access to encoded passwords or whatever determine that I have a crappy password just by looking at the hash? Can they derive any information at all without brute forcing the thing?

 What is this thing? They are on the ceiling in the hallway of the building I work in. A coworker thinks that it is some sort of camera but I think it is a motion detector for the hallway lights. It has red LED lights on it that seem to light up when you walk near it, which is why I think that it's a motion detector.

It's a smoke detector, the LEDs indicate the status. Generally, Slow blinking red means the system is normal, solid red means there's an alarm or a problem

How much of the oxygen you breath in gets released back as CO2? i.e. if you inhaled 10ccs of oxygen, how many ccs would come out as part of the CO2?

Experto Crede posted:How much of the oxygen you breath in gets released back as CO2? I think this will answer your question. I'm too lazy to do the maths, you can do that yourself. It's amazing how much wikipedia answers, and kind of weird to realise that our parents didn't have such a resource available to them. -"I just thought of something specific I'd really like to know more about, but I don't want to go to the library, study the subject intensively, follow a course on it, whatever, to find out about it." -"Sucks, doesn't it?" e: Just to make clear how easy that was to find out: I just set my search field in Firefox on Wikipedia(en), which it's usually in anyway, typed 'breathing', clicked the link 'breathing in gas', and there's the answer our parents would've spent hours, if not days, to find out.

In what, exactly? Sometimes it is -- as either electromagnetic radiation (light, for example) and sometimes as particle radiation ("radiation" radiation). Congratulations, "radiation" now looks like a nonsense word. Thanks, semantic satiation.

If I transfer a photo from my iPhone to my computer, and it is sideways because of the way I held my phone when shooting, I rotate it in MSPaint and then save. Then when I go to upload it somewhere, it uploads sideways again. What gives?

Did a Wikiwar with a coworker, and we did some dabbling over Henry VIII. Everyone knows the legacy of dead wives he left. My question is, since he needed a male heir so bad, why didn't Henry keep a group of women (say, 2 or 4 or so) in a tower or some far-off secluded place, and knock them up, and just wait to see who had a son? Take the newborn back to his pregnant wife and switch the babies out when his latest wife had another girl?

I'm pretty sure if you rotate it using Microsoft's image viewer then save a copy, the copy should be in the correct orientation.

muike posted:Why is waste energy expelled as heat instead of another kind of radiation? All temperature is is how fast particles are moving, so kinetic energy is heat, and every type of electromagnetic radiation can heat something up. Microwaves produce microwave scale radiation to transfer heat. Heat lamps and light bulbs produce mostly visible and infrared radiation that transfer heat. Tanning beds make UV radiation. Even the extreme ends like radio waves and X-rays transfer heat, but just not in conditions that would be safe for you to notice it. All objects that are hotter than their surroundings will emit heat in the form of radiation. The type of radiation is dependent on the temperature of the object. In the 0-300 degree C range the radiation will be infrared, which we can't see (but things like infrared goggles can). In the 300+ degree C range things will start to emit some of their energy as visible light and glow red like molten metal. Hot enough in the 5000+ degree range and something is glowing yellow like our sun. Any much hotter and the color gets washed out since we can't see UV light, so things just glow white. PS: Its annoying that both electromagnetic waves and nuclear decay products are both called radiation, when they are two different things. There is some common history with gamma radiation, but it's confusing to a lot of people who just think radiation = bad.
