Black holes emitted radiation back in the 19th century. Did you know that?
Oddly enough, nothing in pre-20th century physics allowed for that to happen.
It is just barely possible we're about to begin a 21st Century revolution in physics comparable to the one(s) in the 20th Century (Relativity, QM).
Or not. But till you run the experiment (noone is stopping you, you know), your repeated "it doesn't work" comes across rather like a child putting his fingers in his ears and chanting "I can't hear you" over and over....
Out of interest, do the succession of reasons why it "works", you know: it's relativity! er no it's virtual particles! er no it's the Unruh effect! actually cause you physical pain?
No. Those are what are called "speculation". As in "we see it working, but we have no idea why or how. But it could be..."
As to conservation of momentum/energy. They're not necessarily laws of nature, you know. As soon as something comes along that "violates conservation of...", those two rules become "special cases", just like classical physics became a special case of General Relativity.
Now, does it work? No idea, frankly. I'm more inclined to believe the results of, you know, an actual test than someone who didn't do the test but insists it can't work in spite of the test....
Sounds like someone is testing memes to use in "improving" the First Amendment.
Personally, I like that one the way it is, so I'll have to give him a "fail" on his first attempt to spin things as "if only we didn't have that nasty Freedom of the Press..."
The problem arises when you ingest the radioactive material, in which case it becomes extremly dangerous,
There is something called "biological half-life", in case you were unaware. It's based on the radioactive half-life and the time any given thing takes to be expelled from your body.
What that means, among other things, is that the biological half-life of most radioactives is the time between you ingesting it and your next crap (or the one after). So, no, your average alpha-emitter isn't that big a deal.
Caveat: depending on the energy of the alphas, which varies from emitter to emitter, of course. Realistically, you're in more danger ingesting solder (which contains lead, and has an INFINITE half-life) than most radioactives (by "most", I mean anything you're likely to come across in normal life - yes, you can go out of your way to kill yourself with radioactives but it takes some effort. Generally, the easiest way is to gather together a couple hundred pounds/kilos of some radioactive substance and drop it on your head from a height of a meter/yard or so).
I hope that this doesn't reflect their operational environment...
At sea, the operational environment is one six-hour watch followed by up to six hours of PMS, followed by six hours of "everything else" (food, sleep, that sort of thing). Then you repeat (yes, submariners live with an 18-hour day) till you get back to port.
That's with the reactor on, of course. When the reactor is shutdown, you generally get to take it easy - only one watch per 24 hours....
In south germany and south sweden you still can not eat mushrooms harvested from the woods and game is unsafe to eat.
Oddly enough, the wildlife (both plant and animal (and people)) in the Chernobyl exclusion zone are doing fine. Better than outside the exclusion zone, in fact.
So, is the problem in southern Sweden and Germany laws that declare the "safe" level of radioactivity to be so low that the level is impossible to achieve? Or is it more radioactive there than right around Chernobyl itself?
Just so. Article I read before I saw this/. piece stated that it was normal for all those Executive Branch appointees to submit a resignation after any Presidential election....
We keep hearing one political party chant "free markets" and "get big government off our backs!" - yet, where are their actions to implement their words?
Being blocked by the political Party that controls Chicago? And the State of Illinois?
Completely irrelevant to this case, however. A limited time discount is ending. They do that - that's what "limited time" means....
How about the sounds of a team of horses clopping along?
This reminds me of the law passed during the early days of automobiles, requiring that a man walk in front of a car with a red flag (by day) or lantern (by night), so the horses wouldn't be frightened....
The real question is: what should they be doing, and are they doing enough?
They should be mass-producing a standardized nuclear reactor design to replace every coal-fired plant (and then every gas-fired plant). And no, they're not doing enough.
Yeah, this whole secession thing worked really well for the Confederacy, so there's no reason at all it won't work well for California.
Seriously, are these guys expecting that Hillary will be declared Dictator-for-Life if they just make enough "But we HATE The Donald" noise? Sorry, not going to happen.
And just because the EU is telling the UK "buh-bye" doesn't mean that California is going to be allowed to leave the USA....
And if he doesn't, it will be fun being the opposition for the next four years. Opposition suits me, to be honest.
Two years.
Reps have control of the legislature and executive. If they don't fix some things in the next two years, the Dems will take control of the legislature, and we'll have even worse gridlock than we've had.
Note that I'm not advocating any particular fixes. Mostly because I'm pretty sure that MY solutions won't be included in any particular fixes....
What does the Trump win mean for tech? Not a clue.
And I seriously doubt anyone else has a clue either. But we should have a lot of fun poking holes in the Other Guy (tm) who thinks his WAG (wild-ass guess) is better than our WAG....
To be slightly more serious, ignore the Trump win, look at the House and Senate, and you might have less WA in your WAG....
You should have listened a bit more to his actual words. He figured Mexico would pay for it because Mexico is the one losing taxpayers as a result of the current illegal immigration through Mexico. Sort of like East Germany was losing people to West Germany back in the day, until they build that wall (note that it wasn't West Germany that build the Berlin Wall).
And while I don't believe that Mexico will do it either, I consider it more likely that Mexico would want to stop the (brain?) drain than that the USA would want to stop people willing to pay taxes here from doing so....
I'd be surprised if he isn't impeached within a year.
My, you're going to be surprised a lot in the next few years...
He won't be impeached. The barrier to impeachment (you're misusing the word, by the by - impeachment is just the charges part of the process, then comes the trial part) is the 2/3 majority in the House. Ain't gonna happen.
We're going to boot 20 million people off of their health care
I'm curious how we're going to manage that, since only 11M got health insurance (NOT health care) from the ACA.
Note that one of the signature failures of the ACA was that the people who could count higher than three quickly figured out that the penalties for not buying insurance were cheaper than the cost of the insurance, so they could wait till they really needed it to buy.
1: We'll see what happens when the US markets open. But even if they do drop, they are overdue for a correction.
It should also be noted that the markets popped up 4% or so yesterday, in anticipation of a Clinton victory. The "real" drop today shouldn't include first 4% or so, since that would just put us back to where we were Monday morning....
Total income in the US is about $15T. If that were divided evenly between all US citizens, we'd get about $45K each, annually.
Which is certainly more than average now (if you exclude places like Silly Valley and such), but it wouldn't be enough to allow for a 15-hour workweek.
On the other hand, increasing automation will push us in the direction of a shorter workweek, once production reaches the point that everyone on the planet has a reasonable income....
what does escape speed (direction of the velocity vector is irrelevant for the "escape" condition to apply, unless the direction would result in a collision) matter to a "death asteroid"? It can still hit us moving over escape speed....

Hard as it is to believe, you don't have to get into a panic at the thought of a warmer climate to want to save money on your electricity....

Accept her?
Expect her?
Other than her?
Assuming this can be ported to humans, it's the beginning of something huge.
Mind-bogglingly huge, in fact. Since it should be usable for arms, hands, and such as well....

I'm assuming you didn't get very good grades in spelling, grammar, that sort of thing...
That said, if you're ignoring units and just assuming, you don't deserve very good grades in a physics exam. Math exam, maybe....

Convert both to barrels per year, and we get ONE barrel of crude out of ~226000 barrels of sewage.
Hardly an efficient process. Not even sure it's more efficient than just filtering the sewer water for the waste oil that might have been dumped....

Since changes require votes at the Committee level, it's unlikely that the opposition can make any changes.
And if a bill is so disliked that a change can be managed every three days to keep it from final vote, it's probably a really bad bill....
