Terrestrial Gamma Ray Bursts Very Common
Size matters. Length matters.
Or more appropriately, what matters here is the overall energy from the sum of all the photons involved in the dicsussion which are being called gamma rays here.
If I shine a flashlight on you, you may barely, barely feel a bit of extra warmth from the photons hitting your body. If somehow I am able to shine a million such flashlights from the same distance simultaneously, you'll get a million more photons and you'll feel quite a bit warmer.
What is disturbing about these DISTANT gamma-ray bursts is that the energy from so far away follows an inverse-square law as it travels to us. Essentially it spreads out. If you measured the energy hitting a sheet of paper 1 light-year away, you'd find it to be roughly 4 times as much as the energy when you measure at 2 light-years away.
These gamma-ray bursts appear to be from so far away that when we work backwards to calculate what the energy would be like if you were "near" it is mind-boggling.
North Korea Denies Involvement In "Righteous" Sony Hack
Regardless of "good-guy-bad-guy" propaganda, the remark that the South could clean up the North before the allies even got their act together is interesting - even more so with your comment about Northern infantry.
It really doesn't take that much effort to do a quick web search of relatively recent discussions on the matter.
There are likely many reasons the South doesn't want to start a war. But the threat of waves of infantry almost certainly is not one of them. The troop strength disparity simply isn't that strong. The active ground strength isn't more than 2x. Pulling in the reserves drops the advantage of the north to less than 50%. And here's the thing. The South can FEED and supply their troops. If it was Infantry alone, my money would be on the South.
Physicist Kip Thorne On the Physics of "Interstellar"
My intepretation of their comment is that you point directly towards the center of mass and then ACCELERATE (not "drop") "down". Then there is the two-fold assumption that #1 there is an accretion disk and #2 for some odd reason you've decided to go through it. The idea is that it would be rather difficult to maintain your orientation with the accretion disk material pressing against you laterally (not "outwards"... but "sideways" - the gas is orbiting and you're trying not to).
First, I'm curious about the math here. The "intuition" here seems to be that you can push down on your head hard enough so that force downwards on your head matches the mass pulling on your feet and therefore you don't get ripped apart. Even if this works, wouldn't you have to have constantly increasing acceleration/thrust to maintain this balance?
Second, if you've decided to plow through an accretion disk, I'd be more worried about burning up. In any case, if you've got the ability/power to maintain infinitely increasing thrust downwards, I imagine a bit of control laterally would be trivial.
The Strangeness of the Mars One Project
The analogy to Columbus is rather interesting.
Columbus was essentially a dead man walking. Most learned folk knew rather well that his calculations were messed up. Essentially he was significantly off regarding his calculations of the circumference of the globe. People knew this. This is why he had such difficulties getting funded. It wasn't that he was trying to convince people the world was round - he was trying to convince people the world was small enough to sail to India.
And he would absolutely, certainly have died in the open sea had he not lucked out in an incredible way.
Maybe, just maybe, Mars One people will stumble across a fully viable, relatively hospitable, alien population which will save them and propel us into a VERY "New World".
CHP Officers Steal, Forward Nude Pictures From Arrestee Smartphones
Could some kind folk expound a bit on the likely details of how these things transpire? I think folk are getting far too wrapped up in the sordid details here. I don't care if all that was stolen was a simple 2-byte text file. I'd like a better idea of WHEN this happens.
Apparently, if this is/was a "game", then there must be some common reason officers have access to phones. What IS this?!? It certainly isn't your routine traffic stop. What are the likely situations which would make phones available to officers for an extended period of time? When phones are taken as "evidence"? When phones have to be put in a locker or held whenever anyone enters a court?
The article(s) seemed not to go into details here.
Next, the article mentions this was discovered by noticing a few photos were synced. I realize it's a bit harder for iPhones vs. Android, but isn't it still easy enough to transfer files in such a way that essentially leaves no significant record of having done such?
What PREVANTIVE options exist here? I realize without user-controlled encryption, not much is going to prevent the 3-letter folk, but surely Officer Friendly can be thwarted more readily? Again I don't care what kind of file/picture/music/etc. Since the article(s) didn't go into depth, I cannot easily tell whether there was an expectation that the police have access (as in evidence).
Universal Big Bang Lithium Deficit Confirmed
You have to keep in mind that planets are pretty much negligible from a mass balance sheet of anything larger than a stellar system. In our solar system, the Sun makes up between 99.8% and 99.9% of the mass in our solar system.
I imagine you could pretty much presume all planets to be solid lithium and it wouldn't change much with regards to a 3-fold discrepancy.
Google Hangouts Gets Google Voice Integration And Free VoIP Calls
That's not entirely correct. Pretty close though...
There's a significant difference between Mobile Backhaul and bona fide VoIP.
Otherwise stated, when you choose a "no-data" plan you're still getting GSM or CDMA from phone to tower. They almost certainly are amalgating things for their purposes to connect things from tower to switch and through their network. That is essentially "data". And it most likely is cheaper. It's certainly more flexible. But that's not quite the same as "over the data service".
Fasting Triggers Stem Cell Regeneration of Damaged, Old Immune System
Would you be so kind as to comment a bit on your methodology?
There seems to be no small confusion over terms such as "intermittent fasting". I've seen lots of folk use this to mean essentially 16 hours from after an early dinner to a late breakfast. But some of the earlier studies used this term to mean fasting 1 day out of 4 or something like that. A quasi-periodic approach yet indeed fasting for 24 hours (or more) at a time.
I'm curious how you manage your macro-nutrients overall? Do you eat fairly regularly the 11 days? Do you increase protein or caloric intake in general on the eating days? Anything special on the day after the fast? Anything special the day before?
Next, what about your workout regimen? Do you avoid workouts on fasting days? Or specific kids of workouts?
Fasting Triggers Stem Cell Regeneration of Damaged, Old Immune System
But what would be intrinsically different between fasting for a few days so the body says "hey I gotta metabolize some stuff so let's burn up the deadwood" and going low-cal for a longer period of time where the body essentially has to do the same thing?
As long as you follow this with a period of maintenance or balanced intake so the body can then rebuild said immune system stuff, why would fasting be so different from caloric deficit?
Fasting Triggers Stem Cell Regeneration of Damaged, Old Immune System
Does anyone have any idea whether the same effect has been observed for long-term calorie deficit, or low-calorie diets?

Waste Management: The Critical Element For Nuclear Energy Expansion
This would entail the risk of failure in the launch phase which could rain down a nasty amount of stuff anywhere on Earth.
MAYBE when we have a viable Space Elevator would folk give careful consideration to this. Until then, forget about it.
But even then, you'd still have the expense of the Delta-V to get it to fall into the Sun. It almost certainly would be cheaper to send the stuff to Alpha Centuari than to the Sun.
Student Records Kids Who Bully Him, Then Gets Threatened With Wiretapping Charge
Your interpretation of the actions of the police as incompetent are probably mistaken because of a failure to appreciate the true goals and motives of the police here.
This story makes me pause and consider cui bono.
It appears the mother went directly to the principal rather than the teacher. The recording and transcription also seems to cast the teacher in a poor light. So it would seem the initial complaint was as much against the ineffectiveness of the teacher as it was against the bullying itself. It seems the mother had discussed this issue with the teacher previously... repeatedly.
Next, why in the world would the school administration involve the police at all? Do they truly have no ability to manage things at this school without this? No, it seems blatantly clear the goals and motives of the school administration immediately shifted to DAMAGE CONTROL. They never had any concern over the bullying issue itself. The teacher had a reputation to defend. The school was in an adversarial role from the beginning - fighting the complaint, not addressing it.
So... why would the police allow themselves to be used in such a fashion? Because using antiquated wiretapping laws to prevent citizens from recording the actions of police is a rather favorite interest of the police these days. The police had no intention whatsoever from the very beginning to "address the problem" if by that you meant the bullying. They eagerly jumped on board here because they were handed, on a silver platter, a wonderful opportunity to make a loud example of someone to remind everyone they shouldn't DARE record the police. Failing back to disorderly conduct wasn't inept. It was entirely in line with their goals.
Soo... what SHOULD they have done? I am sympathetic with the idea of tossing the video immediately into the Net. But other than the PR or novelty impact, how would this have changed anything vis-a-vis the Wiretapping charge or the actions of the school? I wonder what would have happened if instead, the mother asked for a meeting with the teacher and principal and sat down to discuss these issues, alluding to the transcript only if necessary. At the very least she might have gotten the principal to consider addressing the bullying issue by properly managing the teacher rather than running straight to the school's attorney.
Pluto May Have Deep Seas and Ancient Tectonic Faults
It's all somewhat arbitrary in any case.
It's all just a matter of what we choose to call things and how we choose to categorize things. Lumping things into categories based on similar characteristics is helpful for a number of reasons.
If you go back and look at the history of when and why Ceres (and Vista, and Pallas, etc.) was demoted from planetary status, you'll see all sorts of similarities. The continued discovery of Kupier bodies shows Pluto was part of a larger community, just like Ceres.
What folk mean when they say defining things such that you keep Pluto in and leave Ceres out is that they're looking for a consistent pattern of categorization and nomenclature which minimizes changes. It's simply easier to drop the ninth to to squeeze back in a fifth, sixth, seventh and eighth.
These continued discoveries create the need for updating our categorizations because they highlight the problem of HAVING ALREADY demoted Ceres, Vista, Pallas, etc. It makes no sense to call these new things planets unless we also do this for the bodies between the orbits of Mars and Jupiter.
Navy Debuts New Railgun That Launches Shells at Mach 7
I'm curious how they've addressed the issues of these sorts of things tearing themselves apart. The article doesn't go into details. One has to assume since the overall price per projective was determine that this was factored into things. And the video seems to show something rather purposely placed there that gets destroyed in the launch process.
Anyone find further details?
Small World Discovered Far Beyond Pluto
What will be LOADS OF FUN is the hilarity which will ensue if their hunch is correct that the orbit of this new dwarf planet and Sedna hint at the existence of a planet further out which is several times the mass of Earth.
Are dwarf planets supposed to be BIG?
IPCC's "Darkest Yet" Climate Report Warns of Food, Water Shortages
Please pick up "Six Degrees" and read it.
You are woefully ill-informed if you believe 5C simply "sounds like a lot" but "local variations are far greater". The effects of Climate Change due to Global Warming are not limited to it being just a little warmer. 5C will make things very difficult.
To your point, you need to separate the purported propaganda of us reaching a 5C increase by 2100 vs. the effects of a 5C increase. Yes indeed it is one thing to go on and on about the effects of full scale nuclear war (or a catastrophic asteroid strike, Yellowstone erupting, or whatever) while ignoring the related probability of such an event. But it's foolish to debate the effect rather than said likelihood. These are separate issues/debates. Documenting what has happened in the past at certain temps is probably quite a bit more "settled" than predicting things for the rest of the century.
Back To the Moon — In Four Years
I agree with you on the most part as long as we are thinking of things in the sense of economic/investment value.
Think of anything really and ask yourself whether it makes more sense to build/do such in space or down in another gravity well.
But for raw science, I would hope that we start deploying (very) large telescopes on the far side of the moon.
Pluto Regains Its Title As Largest Object In Its Neighborhood
If you believe there's some pedantic reason to keep Pluto as a planet, I have to ask whether you hold the same views regarding Ceres.
Ceres was "a planet for both the common and technical definitions for quite some time".
The circumstances surrounding demotion of Ceres and Pluto are rather similar. The timeframe either of the two were considered planets is also similar.
Now, what I find more interesting BOTH for this issue of Eris and Pluto and the argument over Planet classification is to look at MASS instead of diameter:
Look at this chart of bodies in our Solar System ranked by mass in a logarithmic chart. The eight planets unambiguously rank as the largest bodies. Eris still is more massive than Pluto. And all the dwarf planets are outranked by several moons.
Yes definitions are arbitrary. But the eight planets stand apart. It does make sense to align definitions to match such. In any case, the definitions OUGHT to be consistent. What criteria other than inertia of publications would you prefer that keeps Pluto IN yet leaves Ceres OUT?
Meat Makes Our Planet Thirsty
For those interested in a casual description of this approach, it's explained a bit in the book "Omivore's Dilemma". They follow around the operations of a small(ish) farm doing pretty much this same thing.
