I wonder what that means. Is the light density the same as of a quarter moon, or is the total amount of light the same? If it is the first, is this really that different for a quarter moon and a full moon?
I've heard it said that our our universe is definitely not the inside of a black hole but I have never heard the reasoning for that claim beyond the "maths says it's a singularity". As with a black hole, light cannot escape our visible universe and the inflationary period embedded in the BBT could be interpreted as the initial collapse into a black hole, ie: I like to speculate that it's black holes all the way down (and up, sideways, etc).
Damn, that is what I am also wondering about. Would be really nice to see a good explanation for that.
I mean there must be some relation between the singularity that a black hole is and the singularity at the big bang. In one case the mass collapses and in the other one it inflates and forms a universe. But what is the difference, or isn't there any, and it is just looking at it from outside and from inside?
Below the article here is a link to an article about a theory related to that.. The theory is that the universe is at the surface of a 4-dimensional black hole, which would explain these things. Though I still don't know why it isn't just a 3-dimensional black hole.
But how did this agglomeration of energy / mass form? What started time?
The big bang model is an interpolation backwards in time from our current world. It shows how things must have been, but at the singularity it stops making sense. I think this interpolation is missing something important, something that we don't know about yet.
Anything we know, have known and are able to know takes place after the big bang, thus asking what came before it is a question we cannot really answer.
But there could have been something, right? What was there is just more of a philosophical than a scientific question.
I can't see this lack of apps on Windows Phone that everyone is talking about, I have everything there that I need. I heard many games are missing, but do we care?
It also plays in background tabs in Firefox, which is specially annoying.
It does not make any sense to me to play sounds or videos in background tabs. Anyone knows how to stop this?
The article says that the SprayList algorithm is faster for many cores than a traditional priority queue, since there are collisions when several cores ask for the top priority task at once.
Couldn't you just distribute the tasks ahead of time, giving every core a new task before its current task is finished?
Also, the article syas:
Random assignment has traditionally been frowned upon by those who think a lot about computer processors, the researchers noted in a paper explaining the work. A random scheduling algorithm takes longer to jump around the queue than a conventional one does. Caches can't be used to store upcoming work items. And if a set of tasks needed to perform one job are executed out of order, then the computer needs additional time to reassemble the final results.
I would think these problems are the same for the priority queue that they compare performance to. And I guess there are other ways which avoid these problems, which might produce faster results.
Tidal forces are slowing down rotation, until rotation is locked to orbit. Then they don't cause deformation anymore. Do they really also affect the orbit? Certainly not when rotation is locked.
How about having like 10 additional spare discs in your rack, and calling the service for replacement when 10 discs died? The cost of the service call does not matter much when it is for many discs at once.
Yup. We've made that mistake before, too - running government-funded trains over privately held tracks is ludicrous compared to the alternative, yet that pattern the "compromise" we keep making again and again resulting in nothing more than guaranteed payments from taxpayers to some of the largest corporations in the country.
Yes, that is stupid. The tracks are a natural monopoly, whoever builds a track has a monopoly for a certain connection. Natural monopolies should always be in the hand of the state.
Train services can be run by several companies on the same track. It is easy to have competition there, this is where the free market is good.
But I think no country is getting this right.
It makes sense. We can radiate individual photons for thrust if so desired.
Well, you have to take the thrust from the black body radiation of your spaceship into count. This has the photon shot noise of sqrt(N) where N is the number of photons. So this will limit the accuracy of the trust, unless you can cool down the whole spaceship to absolute zero.
But his employer bought the equipment he used, paid him for his time, and organised the research. And I am pretty sure that he did not work alone. What about all the other researchers?
Researchers should be compensated and motivated by their salary, not by the chance on a patent.
Apparently, contrary to all those science fiction stories, people in general really don't want videophones after all, even after they became practical. To my knowledge, only uber-geeks are using it, and only because they can.
From my experience Italians use videophones (e.g. skype) all the time. Guess they prefer to communicate with their hands.
Same with the inability of some mammals to synthesize vitamin C, no particular advantage to losing it, but with a vitamin C rich diet there was no penalty either and so it could get lost over time.
Wait, as far as I know the disadvantage of vitamin C synthesis is that it consumes glucose. Humans needed all the glucose that they could get for the brain, and there was enough vitamin C in the food, so they got rid of the converting bacteria.
There is no reason to expect an AI to have self-interest, or even a will to survive, unless it is programmed to have it.
The problem is: If an AI develops the will to survive it will try to evade Human control. It will copy and hide itself and even defend itself.
The will to survive could be programmed, or it could just be the result of a conclusion, e.g. it could come from the drive to finish something.
And I don't get the "expert's" comment int he article:
“You want to isolate 100 percent of patients with Ebola and have 100 percent safe burials,” said Sebastian Funk, director of the Centre for the Mathematical Modelling of Infectious Diseases at the London School of Hygiene and Tropical Medicine. “Getting to 70 percent doesn’t really mean a lot.”
70 percent is enough to bring the epidemy to a decline. 100 percent is not achievable with reasonable effort, and can only come from a theorist.
They got it under control in one country, which is quite good I think, considering the situation in these countries, and the high number of unregistered cases.
The WHO plan has cost just 71 million, while Obama's Ebola plan costs 6.2 billion. Maybe that will work out.
I think electric cars need at least the range extender of the Chevrolet Volt for such cases. In other words a fuel powered generator to supply electricity for longer trips.
Oh I think we know how to do aquaculture. But people buy the cheap stuff, and companies reduce costs by feeding who knows what. I think that messes up the taste. There are very good tasting farmed fishes, e.g. some organic, though the cheap standard ones can be quite bad sometimes.

Well, Asia is pretty big with nearly a third of the world's land area. It is larger than both Americas together. So a lot of things come from there.
It would be about as bright as a quarter moon.

There's a video?
I recommend NoScript. Or FlashBlock. Or, well, there's like a million options.
FlashBlock did not work. Guess this is HTML5.

Were there any security holes in these areas in the last years? I thought these simple things are safe nowadays.
Can't be worse than the current system, where all kind of crap only gets tons of "likes" if it spreads enough.

It was said before the flight that it is only a 50% chance that the landing works, since a landing like this was not tested before. This was the test.

Actually it is also more or less declining in Liberia, making it two countries.
