One could do worse than doodle through a thick engineering pad
and think about how to build a machine around either of these

In a typical unassuming, northern (i.e. completely out of the fucking way, so its as cheap as you can get) suburb in the UK, house prices tripled from 2000 to 2008 and then held steady. Flat for pretty much that last decade now.

Bear in mind that many of these are abysmal, dangerous terraced houses too.

Not quite the kind that are being sold to developers for £1 so they can demolish them, but close.

I have found that the amount of complexity and jargon is inversely correlated with the competence of the scientist. Great scientists, like Richard Feynman, and Albert Einstein, were famous for their clear and simple explanations.

They may have been - WHEN THEY WERE SPEAKING TO THE PUBLIC - academic writing is different matter, maybe you should review their papers to appreciate the difference.

If you look at rock pedestals, then their most severe erosion is strongly at the base. Compare the images with a more typical pyramidal hill to get the difference in erosive force between base and top.

Preventing landed craft from over-tipping with such a strongly concentrated low-level force is a job for outriggers. As the images show, the basic problem is hardly rocket science. You can make the engineering as fancy as you want to cut down weight (e.g. - two only outriggers, which can be re-positioned at ~120 degrees to the wind direction ; the weight of the re-positioning equipment being less than a third outrigger?)

I'm perfectly willing to accept the "stranded on Mars" as a MacGuffin. But that doesn't make it any the less of a hazard that would be addressed and managed. Hey, I could even take it fi there were an inconveniently situated Marsquake in the middle of a dust storm. Or a tube cave opening up under the lander because of the stresses of the lander. But it's still a MacGuffin that flies as well as the Maltese Falcon.

The problem with that is there are blue police boxes all over the United Kingdom. Her for example is one in Glasgow which is several hundred miles/km from London and nothing to do with the Met.

There's one outside Earls Court tube station in London: https://www.google.co.uk/maps/... You can go inside too.

There's no way in hell the harpoon alone is going to withstand 10G of accel without pulling out.

You need to go and visit your local ice-climbing goods store. The tool you're looking for is called a "deadman" (or the mini-version, the "deadboy"). Nobody makes them commercially bigger than about 25cm on edge, because that can, even in loose powder snow, provide the couple of tonnes force needed for fall arrest.

A derived system was actually deployed on Philae as one of the redundant attachment systems. That the comet's material turned out to be far harder than expected points out the main problem : we don't know what the range of comet surface properties is, or how to determine the surface strength using remote sensing.

It's an interesting idea, but I agree that it's unlikely to work. At least, not to the point of bringing the probe up to contact with the comet. It could provide a helluva delta-v to the probe though.

Is this what is meant by 'The Lynx Effect'?

"hard statistical evidence that most likely terrorists are muslims"

Yeah........ when you ignore inconvenient cases such as the Oklahoma City bombing, the burning of churches in the south, dozens of mass shootings, etc. You have to have a pretty narrow view of "terrorism" and/or interpret "most likely" to be 51% or slightly higher to type that statement without without cringing at the hypocrisy.

Says the moron who thinks that the number of churches burned in the USA by white supremecists equals the 400 burned in Syria, 37 in Egypt, and over 400 in nigeria, all by Muslims. And that;s not even starting on Hindu temples and Buddhists shrines. Also are you comparing "dozens of mass shootings" to the tens of thousands killed by IS and the total number could be in millions.

Notice how many of the images feature boys and girls playing with the same toys. They believed in what they were doing: http://www.independent.co.uk/n...

Unfortunately in the 1980s Lego changed their policy and tried to corner the boy's toy market: http://www.womenyoushouldknow....

in the UK, ownership of a tank is perfectly legal

Super Furry Animals had a super blue tank

this seems more like a reusable space container?

Have to admit that's exactly the conclusion I came to when I did a double-take on "Isro's 1.5 [metric] tonne vehicle".

To put this in perspective, that's about the same weight as the current Ford Mondeo (AKA Ford Fusion in North America, apparently); i.e. a typical upper-midsize car by European standards, and lighter than the average American car(!) (*)

(The NASA Space Shuttle orbiter alone is (according to Wikipedia) 78 tonnes when empty.)

I might have dismissed that as a mistake, but the rest of the article seems to suggest that it isn't.

(*) I guessed that was almost certainly the case, and was correct- around 4000 lbs is 1.8 metric tonnes.

There are several to choose from.

165mph through Ashford, Kent.

(I'm sure there are faster examples, and this isn't the top speed of the train, but that could be the track layout rather than the urban area.)

Either you're one of those super-privileged people who live close to the center of London and Paris

You have no idea about London.

When I was a student I lived 15 minutes walk from St Pancras International Station. Immediately north of the station used to be really bad, but since its redevelopment (The Guardian / Google offices etc) you need to walk a little further -- about 10 minutes is plenty.

Council (social) housing on all sides on Copenhagen Street, 0.7 miles from trains to Paris.

The main local issue for the area is the expansion of one of the stations, which is criticised because an area of council houses behind the station would be demolished.

(Incidentally, I live relatively close to LHR, it's about the same time by public transport to either that airport or St Pancras. I'd still prefer the train if I'm going to Paris.)

You might be correct in 10 years or so, if the new government's desired changes to the way social security is paid are fully implemented. (Poor people will no longer be allowed to live in inner London, and the state-owned housing will be sold off.)

does that indicate the depth of the ice or just the surface area? take a look at the depletion of glaciers put "glacier melt comparison" into google and check the "Images for glacier melt comparison" - check the dates on the compared images e.g. https://www.google.co.uk/searc...

An hour to get to New York Manhattan. Not just the airport. You must look at the door to door time it takes.
  What is the time you leave home? What is the time you arrive at your destination? e.g. if would go to Paris, when I look at flying time, it would take 55 minutes with a plane from Brussels to Paris.
By train it would take 1:31.

However I do not live at the station nor at the airport. And those will not be my destination. Say I would go from my home in Leuven to the Eifel tower.
Flight:
Taxi to the airport : 20 minutes (If there is traffic, make that an hour)
Time before departure : 1 hour
Flight 55 minutes.
Getting out of the airport : 15 minutes
Taxi to the eifeltower: 36 minutes
Total time: 3h06 without any trafic. With trafic, add 1 hour easily.

Train: Walk to the station 5 minutes
Train from Leuven to Brussels, change to train to Paris and arriva in Paris: 2:00
Bublic transport to Eifetower : 35 minutes
Total time:2:40

So even now the train is already faster. And these trains "only" drive at 320. I also have taken a taxi, instead of parking and loosing extra time for that and picking up a rental car.

To compare: by car it is 3 hours and 20 minutes. Yes, I am aware that other people do not live 5 minutes walking away fron the train station. Yes, YMMV. The thing is that you need to look at door to door times. I have not even looked at prices. Lowest price I saw to Paris was 29EUR (31.13USD)

And if you are interested, I could be in London in 3h30

It's great isn't it? Google says 1 acre foot is around 1.23 megalitres (reference) or 1230 m^3.

The more astounding bit once you do the conversion is that according to TFS the average individual Californian living in a 5 person household uses well over 300 litres per person per day (reference). I'm from the UK, a place with over twice the rainfall of California, and yet our typical usage per person in a five person household is only 100L/person/day (reference). Even our "high usage" households only use 135L/person/day, only just over 1/3 of the *typical* California usage. What are they doing with it all?

I know the Californians like to blame agriculture for using the majority of the water (true) but these stats are just examples of the monumental waste of water that occurs, both industrially and residentially. If these waste problems were solved, I'd imagine there wouldn't be a shortage of water at all.

"[Iran] did endure an 8-year-long war with what was then Saddam Hussein's Iraq"

That America backed by providing military intelligence and allowing Iraq to fly the Stars and Stripes on its oil tankers (thus making any attempt by Iran to blockade Iraq an act of war against America). At the same time, America blew an Iranian civilian aircraft out of the sky, lied about it not broadcasting on civilian frequencies and awarded medals to all sailors when the ship got back to port. Meanwhile, our erstwhile buddy, Saddam, was using chemical weapons that we failed to condemn as he was fighting a country whose democratic government we had toppled in 1953 and who were "inexplicably" pissed with us. So, yeah, can't trust those Iranians.

"Iran sponsors and funds numerous terror organizations and activities"

And America doesn't?

"Iran ... has stated numerous times ... that their policy is to annihilate a certain other country in the region, and do so by any means possible."

Aside from John McCain "joking" with his notorious "bomb, bomb, bomb, bomb, bomb Iran" song, everybody knows the "wipe Israel off the map" quote was a mistranslation that has been covered many times (see here for a reputable source). But don't take my word for it. If you still don't believe it, ask a Farsi speaker. There is not even an idiom in Farsi for "wipe off the map".

And before you call them biased and say that "they would say that", consider the political leanings of my Farsi speaking friends (and countless other Iranians who came to the West). Clue: they all left Iran in 1979.

I suspect that depends on how the blurring is done and how much of it is done. When you blurr an image you loose information that was previously contained. To get it back, basically, you have to guess. What is interesting, and scary, is that that's not beyond the ability of modern statistical techniques, such as MaxEnt (maximum entropy) refinement.

I grew up in Port Hope, Canada, where Eldorado Mining and Refining was located on Lake Ontario... http://en.wikipedia.org/wiki/E... http://www.toxipedia.org/displ... In 1969 worked for one year at a factory in town called Westinghouse Atomics that made the fuel rods for CANDU reactors... https://books.google.co.uk/boo... http://www.world-nuclear.org/i... Eldorado used to dump truckloads of refined uranium on the loading dock of Westinghouse, which I could watch from my work station, which was then scooped up and eventually turned into round ceramic-like pellets 1cm x 2cm. These were inserted into 2 foot long zirconium tubes. Bundles of the tubes were made to insert into the 50 foot long zirconium calandria tubes in the reactor core. http://en.wikipedia.org/wiki/C... I thought I was quite clever when I snuck one of the pellets out. We all had radiation badges, but no one actually checked them. Everyone that I knew who worked there for a long time eventually died young of some type of cancer. I only worked directly with uranium for 6 months, but in my late 50s I developed rheumatoid arthritis, which apparently is rather unusual. They used to dump waste sludge behind our high school, where we all went to smoke dope after class. Subsequently there was a massive cleanup in many areas of the town. http://bmjopen.bmj.com/content... https://books.google.co.uk/boo... http://www.world-nuclear.org/i... How does all this relate to the original topic? Well, at the time, everyone thought it was harmless, like the toy. Everyone I worked with at the time could be called a chav or a redneck or a good old boy - some of them were really good people, some not so.

This is kind of nonsense.

In most current compilers for ALGOL derived imperative programming languages (such as C, Java, C#, Pascal...), it's true, because, TRADITION! But it's not true of the underlying hardware, and it's not true of any compiler which implements its stack as a linked list. In principle there is no reason at all why you should not allocate all your available store to stack. There's also no reason why you cannot dynamically implement your stack in your heap.

These are all language (and run-time) design choices, and just because the people who specified ALGOL in 1958 - when I was three, goddammit - were working on machines which were (by modern standards) desperately poor of both mill and store, doesn't mean that we need to continue to copy the design choices they made then.

It is partially based on the Scout badges concept. Like those, I think that the biggest impact will be in providing a way to showcase skills rather than academic achievements. This means that they are likely to have more value for those who aren't the academic high-flyers, but who have a great set of skills, interests and achievements that they want to make people aware of.

In some ways, the badges are an alternative to paper certificates (or sew-on patches) but, being digital, have some significant advantages such as being easily shareable, verifiable and have links to evidence for earning them. Raising awareness of the potential among the general public and employers will be key to whether they take off or die on the vine.

Full disclosure: I've done a bit of research into the use of digital badges in universities. For anyone interested in reading a bit more, freely accessible versions of my papers should be available from https://scholar.google.co.uk/c...

jetliner wheel brakes don't have to last much beyond bringing an aircraft to a dead stop. Hypersonic airframes have to withstand constant high temperatures and aerodynamic stress. CC can't do the former without oxidising (threshold of oxidation on carbon composite is about 1650C while the skin temperature is tested at 2000+) so a coating is needed that only needs to withstand the high temperature without decomposing. Elemental metals are out, as are superalloys, silicon composite is definitely out since at these temperatures it does as designed on SSO heatshields: it evaporates giving the airframe a shield made of hot plasma (which will not only disrupt the airfoil but the oxide coating as well), something else has to be found.

If you have an appropriate Android device Google Now will (apparently) display information based on your current context (e.g. if your phone learns where work and home are it might display information about traffic jams on the route home around the time it believes you will be traveling). You need a logged in Google account to use this feature.

OK Google is a way of using your voice to interact with your device (or Chrome web browser). So if I have the appropriate phone and it's been set to listen I can say "OK Google" and it will activate an app/mode where it will accept further voice input. On the Android phone I saw (and in my Chrome web browser on OS X) I can then ask it "What's the weather like?" and it pops up some weather related information and speaks back "It's ten degrees in ". Sometimes when you ask it questions just does a web search other times (on the device) it would start applications (e.g. mail) and so on. You do not need to be logged into Google to use this feature.
