Yikes, that scenario had never occurred to me. I just turned TouchID off on all my devices. Entering my (>4 character) passcode isn't really that hard.
This sort of story is why I like Slashdot. This was interesting and useful. Thanks to the submitter and the editor.
I was surprised at the number of (what appear to be) meteor craters; I knew that Pluto is in the Kuiper belt, but I always had the impression that the density of that belt was really low. OTOH, Pluto has been wandering around that region for billions of years, so I guess that adds up over time. Very cool!!
Actually, momentum is NOT conserved for the *shooter*. He is bracing himself against something (his feet on the ground, usually), so there is an external force acting on him. Thus, this particular argument fails.
For the victim, if he is shot unawares (so he doesn't brace himself), then conservation of momentum *does* apply. I calculate that he will experience a force to his chest of about 35 newtons (~8 pounds). That's not much, and won't accelerate him much.
However--it may well knock him down. The reason is, the force to his chest will cause a torque on him, which will cause him to rotate down to the ground. If we assume he rotates about his feet, and treat him as a solid cylinder (reasonable approximation) then I get an angular acceleration of about 0.4 radians per second per second (22 degrees per second per second).
That only lasts while the bullet is in contact with him, of course; after that, the victim has a gravitational torque on him, with a corresponding angular acceleration (I estimate) of 9 rad/s/s.
If someone wants to check my work, I'll supply the numbers and things I used. I might well have made a mistake or missed something.
I got the Ikea Bekant http://www.ikea.com/us/en/catalog/products/S99022526/; it's great, solidly built, and less than $500US. I used a felt pen on the legs to mark my optimum sitting and standing heights so that I don't have to take five minutes fine-tuning the height every time I change heights (which would have guaranteed that I would never change the height!).
Sometimes I change multiple times a week, sometimes multiple times a day. It's great.
Sounds like a projector would be perfect for you, if your TV room would work with one. Price is (or can be) comparable to your average TV monitor, for an image 2-3 times larger, and just as HD.
If there is a decent brick-and-mortar store within a reasonable driving distance, I'd shop there. Of course, this won't change what quality batteries you find, but--Apart from the issue of supporting your local economy, if the battery fails within the warranty period, it's a heckuva lot easier to return/replace/exchange it than trying to fiddle with an online retailer.
Plus, some stores (my local Batteries and Bulbs store, for example) can open many devices that are not designed to be opened by the average consumer. Finally, they are a LOT more likely to sell you the correct one on the first try.
And in fact, when I buy a movie via iTunes, I have the choice of streaming it directly from Apple servers, or downloading it to my computer--or both. I generally choose to stream directly, because I'm lucky enough to have an internet connection that is both fast and reliable, and Apple's servers have been very reliable (not 100%, but close enough), so I don't have to use up my hard drive space.
But, if I choose to, I can have the full HD version on my local hard drive, and so can watch any movie I buy whether or not I have an internet connection.
(N.B.: I know I sound like an Apple fanboi (TM), but it's the only online service I've tried.)
Baseline: I am a trekker; I really, really like all of Star Trek, old and new.
For all that it was the genesis of all things Trek, TOS is terribly painful to watch these days. Not an auspicious starting point for a fan-made series.
What's funny is that they managed to write a story that was the same quality as most of TOS stories--mostly low; the actors reproduced the acting "skills" of the originals (especially Kirk! Wow!); and it was just as cheesy as the original show. I fully expected it to be hard to watch.
But it wasn't! It was a labor of love, but they managed to go above that, and actually make an enjoyable episode, one that can hold its head up with the all but the best TOS episodes.
Hats off to them all, and I think I'll open my wallet.
I hate to be Captain Obvious here, but isn't it true in general that the more advanced the operating system, the better (newer) the hardware it needs to run well? Nobody who values their time or sanity tries to run Windows 7 on a Pentium Pro computer.
So yeah, older iPhones will run the new iOS more slowly than they ran the older iOS.
With respect, if you think Google+ is moribund, then you haven't looked at it lately, or you haven't looked at it deeply enough. Among the active G+ members are the Large Hadron Collider (they hold live Q&A sessions on G+ frequently), MIT, American Physical Society, Cmdr. Chris Hadfield (commander of the International Space Station), Wil Wheaton...Active communities include a Python community, Android, IOS, Science, Physics, Social Science, Medical...Popular culture communities include Doctor Who, Star Trek, Red Dwarf...The list is very, very long.
In short, go check it out.
(I read somewhere, probably on Slashdot, that "Twitter is for following people you don't know; Facebook is for following people you used to know; Google+ is for following people you should know.")
I have a question for the Slashdot community: Does this shooting alter your opinion on the issue of gun ownership rights vs. gun control laws? Even a little, in either direction?
Please note: My question is NOT, what is your opinion now; rather, it is, how much did your opinion CHANGE?
We have a large enough community here that I think the numbers will be statistically meaningful.
"The act of measurement bridges the quantum and classical worlds by projecting a superposition of possible states into a single (probabilistic) outcome. The timescale of this 'instantaneous'process can be stretched using weak measurements usuch that it takes the form of a gradual random walk towards a final state. Remarkably, the interim measurement record is sufficient to continuously track and steer the quantum state using feedback..."
The way I read this, they aren't claiming they prevented collapse, nor that they can predict which state it will collapse to; rather, they have (1) increased the time of the collapse of the wave function (via feedback) and (2) been able to "watch" the electron collapse to whichever state it goes to. [N.B.: I am totally open to correction. I haven't paid the $32 for a copy of the paper.]
You need to install a multi-layer object made of two (or more) materials that transmit sound waves by very different amounts; this is known as an impedance mismatch. It Can Be Shown that the incident sound waves will be strongly reflected at the mismatched boundary. In this context, double-paned windows (thus layers of glass and air) will provide the mismatch you need.
And, as another poster mentioned, this will provide good thermal insulation, as a bonus.

If I build a house and install a flimsy lock on its door, and someone breaks through it into my house, I'm not the one who committed a crime.
Agreed! Also, volcanoes on Charon that erupt with water-based lavas! https://www.nasa.gov/feature/pluto-s-big-moon-charon-reveals-a-colorful-and-violent-history/
I believe they mean "from the top of the image downward towards the bottom of the image".

Plaudits to the New Horizons team! Yay science!

Well, Apple didn't make me pay for the upgrade from Mountain Lion to Mavericks...
They didn't make me pay for the upgrade from iWork '09 to iWork 2013...
They didn't make me pay for some music I bought that was re-issued as remastered shortly after I bought it...
However, you're quite right about having to buy new equipment. That would be true regardless of whether I stream or use physical discs, though.
In a movie theater, which uses projection, the curved screen is to alleviate the pincushion effect (http://en.wikipedia.org/wiki/Pincushion_distortion) created by the anamorphic lens (http://en.wikipedia.org/wiki/Anamorphic_lens) that the theater uses. This is utterly irrelevant to the image created by a monitor TV.
In short, yes; pure marketing BS.
I decided to move completely to streaming (via iTunes), rather than buying discs. Two advantages:
1) When the next format comes out, I don't have to re-purchase the same movie yet again (VHS --> DVD --> Blu-ray --> 4K --> ???)
2) Less stuff in my house. I am trying to downsize, and I want my next house to be less than 1000 ft^2. The less stuff I have to store, the better.

Have been using iOS7 for ~3days.

So, no Heisenberg compensator here.
