Corbyn also blames the Ukraine crisis on the west and ticked off Poland by saying that they never should have been allowed into NATO and instead "should have gone down the road Ukraine went in 1990". He thinks Britain should leave NATO, but recently backtracked, saying that there's no "appetite" among the public to do so at the moment and he'll respect that. Russia basically endorsed him today.
That is, of course, not how 238Pu is made. Neutron bombardment of uranium yields far too much 240Pu mixed in with the 238Pu**, and it's too much cost and difficulty to separate them. Instead, it's made by first taking nuclear waste and isolating the 237Np from it, which makes up only a very small fraction, so you have to process a lot. You then expose the relatively pure 237Np to a heavy neutron flux (which is expensive, as neutron flux is valuable), very slowly converting it to 238Pu via 238Np. You then regularly have to extract out either the 238Np, 238Pu, or both. It's an expensive process. 238Pu is a manufactured product, not a waste product.
** Uranium is mainly 233U, 235U, and 238U. We'll ignore 233U because it's so far away from 238Pu for now, and we'll ignore fissions, which are very unlikely to lead to Pu. 238U captures to 239U, which quickly decays to 239Np. This captures up to 240Np, which decays to 240Pu. 235U captures to 236U, which has too long of a half-live to be relevant. It captures to 237U. This can then either capture up to 238U (leading most likely to more 240Pu), or decay to 237Np. This then gives us the above route to 238Pu. But the longer series of bombardment chains needed, the comparative rarity of 235U to 238U in most reactors, and the cross sections involved, usually mean that under 2% of plutonium in nuclear waste is 238Pu.
Yes, 90Sr RTGs. Which is why I said it's much more suitable. It's cheap (by nuclear standards) and abundant - it's a waste product, not a manufactured product like 238Pu.
Does India actually have a stockpile of 238Pu? If not then where are they supposed to get it in two years? It's not like the world is awash in the stuff, and it takes time to set up a program and make it.
Honestly, Chandrayaan-2 is only a near-Earth mission, and not a super-long one - they don't need a long half-life element like 238Pu. Dirt-cheap 90Sr probably makes more sense, it's a widely available waste product. Or if India really wanted to impress the world, they'd make an actual nuclear reactor for space missions, not just an RTG, and offer to make them for sale to other countries. Russia made a few of them near the end of the Cold War (TOPAZ), but it's anything but off-the-shelf technology today. Another option to do something actually noteworthy would be to make a stirling RTG and leave on the moon, racking up operational hours in a space environment to demonstrate its reliability. A flight-tested stirling RTG would also be something that the west doesn't have.
Given that they were donated at no cost, precisely zero seconds.
It's still stupid, but no, they didn't pay for them.
That said, we keep seeing the stereotype that the key ability to successful police enforcement is to be able to drive faster than the criminals. Which is nonsense. The strength of the police force versus criminals is that there's a million of them, pre-scattered across the country, and they communicate with each other in realtime. You don't have to catch up with the fleeing perp, you're already past them - or at least, another officer is. You just need to not lose them (aka, a helicopter, or better, a drone; things like StarChase help too) and keep the net around them tight enough that you can nab them if they stop (which has to happen eventually), but not so tight that they feel the need to drive like a maniac and endanger the public. Heck, you can even make them stop in a place where they're no threat to the public, such as spike strips on a closed road or the like. But you never need to have car chases through busy public areas - at least not for more than a brief initial period. It's pointless.
There's a interesting statistics on the topic here. 91% of police chases are over non-violent crime. 233 suspects and their passengers (some of them innocent) die in police chases every year in the US, as well as 87 innocent bystanders and 3 police officers - more than the number killed by floods, tornadoes, lightning and hurricanes combined. 42% of police chases were over nothing more than simple traffic infractions. 15% were for suspected drunk driving - which just adds even more danger to bystanders.
Police chases make great TV, but usually they're hardly worth the risk unless there's a serious danger of A) losing the suspect, and B) the suspect committing a violent crime after being lost.
Maybe "harder", but only in relation to certain types of things (things might be seen in public by people who you know). Which also has downsides, such as encouraging self-censoring public behavior (most people here for example generally don't dance unless they're drunk out of fear of what people who know them might think). Also, we're not exactly a shining model of a free and independent press here, which combined with our low population ( = fewer people investigating) makes it harder to bring scandals to light. But I have hope for the pirates - if they can keep up their standing in the polls, they'll win a landslide victory in the next election. What I wouldn't give for a Pírati-Samfylkingin coalition!
Anyway, though it's counterintuitive, the best place to not be spied on is... the US. Even though the US is doing most of the spying (notwithstanding the best efforts of the Russians and Chinese to catch up;) ). The US has a ban on spying on its own citizens without a warrant which it tries - however imperfectly, in numerous regards - to enforce. For people outside the US's territory, it's open season.
Indeed. I have an Xperia Z2. Great phone, I love it (although definitely get a protector! The glass never ever scratches but it will break if you drop it too much/too hard/sit on it at a bad angle/whatnot). But the waterproofness is conditional on the plug over the USB port being in. But the plug likes to come out sometimes. So, you're probably fine if you check the plug and make sure it's fully secure before you get in the water, and don't fiddle too much with it. But it's certainly possible to screw up.
That said, when you use it properly, it is indeed waterproof. I've used mine in the shower (although that's a bit tricky as the water droplets can count as screen touches) and fully underwater in the sink (easier to use there). I've never taken it in the pool but I have no doubt it would be fine there... again, conditional on that plug being right in position.
If I could change one thing about the phone, I'd gladly give up the USB port and just use inductive charging in order to have the waterproofing be more reliable. I never transfer data over USB.
Are you talking about a particular incident or just in general? Martian meteorites are identified by the gas trapped within them, general isotopic ratios, and a number of other factors.
I don't see how a population whose skulls are literally half the size of a typical H. erectus skull (among many other major differences) could be seen as just another H. erectus. And not just one, potentially deformed individual, but 15 individuals with the same characteristics. And even if they were the same species, this would still be a remarkable find - so many full, intact bodies in the same location. In a weird location, and in a land far from where H. erectus was known to have lived.
Dawn is actually an averted disaster due to its failed reaction wheels. The mission team came up with a really clever plan to achieve all of the same science goals using even less fuel than had been planned by using the ion engine more, not rotating as much in Ceres orbit, etc. It's slower, but they saved the mission.
Whoa... just noticed that the grabens seem to be younger than the (presumed) salts, even going straight across one of the super-bright areas. Seems to make it hard to envision that both were simultaneously caused by impacts (my default presumption). Seems to me that if this was caused by an impact, the active tectonic forces persisted for long after the impact (say, due to resultant localized internal heating), long enough for the salt flats to fully develop, lose their volatiles, and fully relax; or otherwise, that the forces that made them are unrelated to impacts altogether.
Oh, I can't wait to hear what the experts come up with!:)
What I've read from following the story at the Planetary Society blog (and assuming I'm remembering correctly) is that the team does not find the spectra of the bright spots to be indicative of ice thusfar. They still don't know what they are but salts of some sort are a leading hypothesis.
Very interesting terrain coming into view here - and not just how the bright areas seem to all be localized depressions. There's a lot of fine, very straight rift/fissure structures, like some sort of horst/graben terrain, tracing their way across the crater. Almost like Enceladus's tiger stripes or some of the rifting on Europa. We also see such terrain here in Iceland due to continental spreading. The features run parallel to each other locally but the directions are different in different parts of the crater, so whatever the cause of the pressure differential, it's nonuniform across the crater. Really fascinating to see!
If I had to speculate wildly... I'd wager that it might be a sign of localized (and perhaps extinct) soda cryovolcanism like on Enceladus, with the water sublimated off and only the salts left behind. But that's just me talking out my arse;)
Both times the plastic door has broken on the floor after falling. It could be epoxied back together but would be pretty ugly - and if not epoxied right then the hinge positioning would be off. It's all one piece, there is no separate hinge, just two nubs on each end that slot into holes in the refrigerator where they can rotate freely.
Not everything is as tough to fix as a washing machine. For example, I live in a little island country and imported low-volume goods are very expensive. A hinged plastic door on the cheese compartment has now twice fallen out of my refrigerator - whether the hinge breaks first or after it hits the ground I don't know, but it's some sort of design flaw. It's just a little piece of thin plastic, but getting a replacement costs about $40 USD. It would be a lot cheaper to 3d print a new one... but of course, like 99.99999% of all parts on Earth, there's no publicly-available model.
Hmm, maybe I should check into whether anyone in the country has a 3d geometry capture setup... then I could not only print out a replacement, but also modify the model to stop it from breaking and/or falling out so readily.
There are design advantages to not having the battery removable - the obvious (for example, not having to have weight and space for a hinging or slide-latch mechanism) and the less obvious (for example, waterproofing and dustproofing - the fewer openings, the better). When last shopping for cell phones I picked a model with no replaceable battery because, no surprise, the phones with the best waterproofing on the market also didn't have replaceable batteries.
Physics 101: 200lbs man vs large rock: large rock wins. 200lbs man vs pile of small rocks: man wins.
Not according to every stone wall built throughout human history. There's a reason they're made out of smaller (albeit still heavy) rocks: it's far, far more practical.
Indeed, they need to become civilized like Britons. If they want to sleep with a sex slave or deface cultural monuments, they should have to book a trip to Thailand just like everyone else.
