Here's what, though: there are plenty of adults who have no clue that their actions will lead to something illegal, yet they routinely get handed criminal sentences. So your argument somewhat falls on its face.
It's not impossible. In this case I don't know any details so I can't say anything more than IMHO it'd be unlikely. But it's certainly possible for two 4 year olds to conspire to kill someone. Rare, but possible.
My daughter is 6 and has had an IMHO proper grasp of the concept of death for a good 6 months at least. Namely that death is irreversible, that certain actions are likely to cause it, etc. Or else I don't quite get what you mean by "proper grasp of the concept of death". Sure, if someone is avoiding in-depth talks about death simpy because the kid is "too young" -- then the kid's lack of grasp is merely a projection of parental reservations, not something innate.
In English? Wow. A straight-phonetic language like Spanish, or any of the Slavic languages -- I'd understand that. But in English you most likely were merely able to recognize common words by sight. Real phonetic decoding skills in English take years to learn. The real test of this is whether you can pronounce nonsense words correctly. In Spanish or say Polish -- it'd be trivial, in English -- ha ha ha.
I'd think that there's plenty of yet-to-be-found exploits to be found in USB stacks of all popular OSes. They are only dormant because crafting custom USB packet exchanges is not exactly as trivial as crafting custom Ethernet packets. But I'd think that the time will come where someone will publish code that you can run on anty device supporting Linux gadget API, and upon connection to then-current Linux or FreeBSD host it will give you instant ownage. Same on Windows will follow shortly -- it's just a bit harder to do on a closed-source OS.
Admittedly, now I don't really know who are you replying to: there's plenty of posts here that are replies at one level above where they below. So no offense.
Ain't no such thing, or else something as basic as an electronic weigh scale wouldn't work. To rephrase: solid metals are compressible enough to measure the effect (strain) due to very reasonable external loads -- you'd think that liquids would be, too. And yes, they are.
Bulk modulus of steel, commonly strain gaged in weigh scales: ~160 GPa Bulk modulus of water: ~2.2 GPa. Water is on the order of 100 times more compressible than steel. Yet steel's and similar metals' compressibility (modulus) is routinely used in measurement applications!
Now to give you an idea of how compressible metals are: a soft iron sphere with a single strain gage bonded to it will give you, IIRC, 1m depth resolution if you hook it up to reasonable digital strain meter. I did the math once on Yahoo Answers somewhere, don't have the link handy.
Don't believe all they tell you in grade school for a lot of it is bullshit.
What kind of a fucked-up design was it that didn't have pressure sensors in each and every cell? Engineering fail. The manufacturer deserves nothing less than losing money.
I guess the OP's point just whooshed over. It doesn't matter what the car is -- if it's anything feasible, it'll be in the same ballpark. DUH! It doesn't matter if it's 1.8MW of instantaneous power needed, or 0.5MW as you'd have if you were driving a completely infeasible aerodynamic pipe dream. The problems are of the same magnitude.
Perhaps the battery could be designed so that it's easy to take it apart and reuse most of the parts -- as opposed to recycling that would imply grinding them and reprocessing into feedstocks. The only teensy weensy problem is that no such reusable designs have been demonstrated so far. It may be a simple thing to do, or it may be a very significant engineering feat -- I don't know.
I don't even know who and WHY the heck came up with the idea of "hydrogen economy". It's entirely unfeasible and pointless. Hydrogen, other than liquid hydrogen, is an absolute pain to process and transport. I somewhat like it only because in case of a vehicle fire it's much safer than gasoline, but it'd need to be stored in liquid form in low pressure insulated tanks. Vented, no less. Handling cryogenic liquids is no fun, and if you drive off with the fill line still attached you're likely to severely damage the filling station (read: enough spilled liquid to ignite and burn and melt a few nearby pumps).
The oft-touted fact that exhaust it water is pretty much irrelevant, because everything else is so much more problematic. It's like arguing that having a coal power plant burning dirty brown coal is good because there's a water desalination and purification plant hooked up to it -- look ma, it's plenty of clean water coming out! Yeah, right.
EV batteries won't be "half-dead". It's not like your average notebook or tool battery pack.
Each cell has a management board that knows its condition, measured capacity, and that can bypass it. When you swap batteries, the price you pay includes some depreciation cost that covers replacement of dead cells etc. over time. So you pay for energy and upkeep of the batteries. Not unlike when you replace propane cylinders -- you pay for cylinder upkeep and testing, and for the propane (energy carrier).
An EV battery can still be fully functional with a few cells completely dead (as in open circuit) -- the management unit would bypass such a cell. The cells also don't die as easily since they are never overcharged or over-discharged.
AFAIK, and I'm not a grid engineer or anything like that. The nuke plant needs a bit of its own power just to keep going, it also needs to provide a bit of its power to other parts of the grid just to keep everything in sync. You basically can't utilize 100% capacity of one plant that's in the grid. You need to share the supply with other sources in the grid. Now if every plant in the grid is either nuclear or hydro, then of course all your power will be nuclear-sourced, just not coming from any one particular plant.
In an "all-nuclear" grid you still need hydro plants for energy storage and load buffering throughout the day. Nuclear plants are best run at constant power, the time constant for power change is IIRC measured in "summer afternoons", let's say there are three afternoons per 24h;)
You're only partially correct. At the powers we're talking about, you can't have a simple rectifier followed by a buffer capacitor -- the peak current would kill the power distribution system.
You need a power factor correcting (PFC) circuit -- essentially a rectifier followed by a "small" capacitor that only supplies the ripple current to the step-up converter. The step-up converter generates a constant DC voltage by boosting the unipolar (pre-rectified) AC; it is designed so that the current is instantaneously proportional to voltage. The average current is then proportional to the demand on the load side. A PFC is then followed by a step-down converter that provides the charging regulation (voltage or current, as desired). There are designs where the PFC is integrated with the final inverter, all using one switching transformer core.
Exercise for the reader: select any article on the site. Any one. First one or two sentences are enough. Copy-paste into google. Have fun finding original sources for most of what they threateningly repost. If not all, that is - my 6 random tries were all successes. I think it's them who are in hot water.
That's pretty misleading since the bees are only dealing with "a few hundred" flowers. At brute force that would take your cell phone maybe a couple minutes to solve.
Iterating over a "few hundred" factorial in a couple minutes? I want your cellphone. Heck, better not, I think that quite a few of world's intelligence organizations are looking for you just now, maybe I'll let you see how it pans out first;)
I agree about 3am calls etc., but when you're both awake and not somehow temporarily confused, you should be able to communicate just fine. If someone I knew suddenly started having prolonged problems like you describe (conversation w/o communication), I'd get them to see a neurologist, fast.
Smalltalk gets boring very quickly. You must have high tolerance for boredom. For me, a conversation where I don't learn anything new and interesting in a couple of minutes is basically wasted time.
You have obviously never chatted with a not-overly-bright teenager. It feels like a complete disconnect most of the time. Even in face-to-face conversation. You'd think they replaced their brains with a broken chat program or something. I'm dead serious.

Not a tranformer, but a power converter. A good one should have ~95% efficiency, so it's not that big of a deal.

Thank you, thank you, thank you! This deserves +5.
At least there is one poster app for Smalltalk -- MIT's Scratch. Cross platform and works just fine. Other than that -- meh.
If she had no interest in what I'm telling her, then sure -- but then I wouldn't start boring her to death in the first place.
If she wanted to know it, I'd do my best to explain it step-by-step, making sure that each step is understood.
