Didn't Tom Baker's Doctor once visit a refuelling plant on Titan only to be menaced by a giant prawn with scary eyebrows?
Oh look on the bright side - it's not Richard Hammond.
Awww crap I'm gonna bite (wish me luck folks).
Since I've done radiodating of geological samples I might be speaking with a small amount of (slightly hung over) authority, or I could be part of the evil cabal of earth scientists who are hoping to become infinitely rich by telling people the world is really, really, really old (and very cool - apart from the hot bits obviously).
The age of the Earth isn't solely derived from U->Pb dating (although that was the first method tried). The relative volatility of lead is a real problem with older samples which are likely to have been metamorphosed since original crystallisation. Instead the range of dates for the formation of the Earth is based on various dating methods including Pb -> Pb, Sm -> Nd, Rb -> Sr and Re -> Os, all of which come in around 4.51 - 4.68 Gya with a typical range of +/- 0.15Gy.
Pb -> Pb dates are referenced against a geochron which was taken from meteoritic dates of IIRC three stony meteorites of different compositions and two iron meteorites. If you want detail look up the Holmes-Houtermans method for Pb -> Pb dating. Basic chemistry tells us that the iron-nickel troilite alloy of iron meteorites is depleted in uranium so it will not contain radiogenic lead derived from uranium decay. So the ratios of lead isotopes in iron meteorites are those of the primeval solar system.
C-14 in diamonds? If you're talking about the Baumgardner and RATE work, it has been heavily criticised for not following proper procedures in handling carbon isotopes. Anomalous radiocarbon readings are occasionally found in studies of carbonates, but the fact the vast majority of geological samples do not show radiocarbon forces us to conclude that the problem is either with instrumentation or with the way samples are prepared for analysis.
Ocean salinity? Really? Seriously? You're still using that one. Look Edmond Halley didn't know how evaporite deposits form or how widespread they are. T. Mellard Reade, John Joly and George Becker didn't know about plate tectonics - they didn't know that ocean waters (containing salt) are in intimate contact with magma at mid-ocean ridges; that a volume of water equivalent to the entire ocean passes through the oceanic crust every 10 million years; or that salt water is subducted into the Mantle in ocean plates and sediments.
In short, a lot of science has happened.
'That jellyfish is a terrible design. Not complex enough. Back to the drawing board! ;)'
But it might be immortal...
It means the proteins used in vision evolved first in jellyfish so we probably have common genetics. Our system of vision evolved much later with the first vertebrates. Nautilus has a pin hole eye whilst other cephalopods have a completely different (and in some ways superior) vision system using the same basic chemistry and genetics, the trilobites had yet another and so on...
The AGRs were horribly over-budget and had a pretty terrible reputation for reliability when they first came onstream, but they were incredibly ambitious pieces of engineering at a time when Britain was really losing the knack for big projects and industrial relations were in the crapper.
It's a real shame as some of the ideas were good ones, such as producing steam at the same temperature and pressure as a coal-fired plant allowed commonality of equipment between stations. By the time the AGRs were commissioned their price per unit far exceeded that of the PWR which had been churned out by the hundred. So when it came to ordering Britain's third generation stations there was no choice but to go with the PWR. Which was a real shame, because once the AGRs were debugged they turned out to be pretty reliable.
I'm still trying to work out why the Canadians have never tried to sell CANDU in the UK. It addresses all the cooling problems of the PWR and the contamination of coolant in the BWR and is ready to go.
But I won't believe this announcement amounts to anything until the ground is broken. I've lost count of how many times in the last 20 years the UK has announced the go-ahead for new nuclear only for it to be cancelled when the economics intervene. After all, the price per unit and the level of government subsidy that will be required if the cost of electricity falls below the floor required for new nuclear have yet to be agreed.
Very happy Kobo Glo user here.
If you're not already in the Kindle ecosystem the Glo is every bit as capable as the Kindle.
I trust that's world beating as it sweeps as it cleans. God I'm getting old.
I've got one of the Dyson fans (or air multipliers as they wankily like to call them). I dunno about the hi-techtitude of the brushless motors but they sound like Concorde starting up on a cold morning.
Hopefully this helpful cut-out-and-keep chart will resolve all the problems between creationism and science:
Did you know dinosaurs died out in 1927?
'This would mean a new vent. Am I looking at it wrong?'
I can't tell either. But it's not impossible - almost all volcanoes have parasitic cones and fissures low on their flanks - the pressure of pushing a column of magma into the vent is often greater than that required to open a vent on the side.
Sorry to be the bringer of bad news - it's not going to go bang, it's the wrong sort of volcano.
You're looking for andesitic and rhyolitic volcanoes found in continental interiors and on island arcs. Basically you want lots of silica to make the magma sticky and lots of water and carbon dioxide to provide the 'umph!'
Unfortunately, Heard Island is fed by the Kerguelen hotspot which brings very low silica, volatile poor magma from deep inside the Mantle. The volcanoes in the hot spot are basaltic, producing lava flows, very little ash and even the occasional lava lake - something like Hawaii - but with penguins.
'No, it's a balance. An excellent French teacher probably can't teach Physics, a good Computer Scientist probably can't teach the subject, without being taught how to teach'
I agree, but isn't the point of Gove's free schools to allow anyone to set up, run and teach in a school no matter what their qualifications (or otherwise)?
Conodonts are an extinct class Conodontophora; conodont elements are the hard microfossils which are used for stratigraphic purposes. They may or may not be teeth.
'What about life around the deep-water thermal vents? Is there any evidence of when that started up?'
The last time I was trawling the literature the evidence from genetic studies of the various species found around hydrothermal vents is that none of them are older than 100 million years and all have links back to well-established species found in more 'normal' conditions.
There are about half a dozen known vent provinces around the world with very little commonality of species between them. Instead it appears that different species evolve to occupy the same niches in different places.
Whether life started there remains an open question.
Has Lewis actually read the paper in question, or just the abstract or various digests?
I'd have thought the cultivation of food crops and the creation of cities defined the current epoch slightly more than a slightly smaller, slightly thinner, slightly less useful laptop - but then again I'm not in marketing.
And we should never forget Operation Acoustic Kitty:
'Acoustic Kitty was a CIA project launched by the Directorate of Science & Technology in the 1960s attempting to use cats in spy missions, intended to spy on the Kremlin and Soviet embassies, recording the links between the buildings in the area. A battery and a microphone were implanted into a cat and an antenna into its tail. This would allow the cats to innocuously record and transmit sound from its surroundings. Due to problems with distraction, the cat's sense of hunger had to be addressed in another operation. Surgical and training expenses are thought to have amounted to over $20 million.'
There will be a cassette version won't there?
So they're not getting rid of any paperwork, just giving them a piece of technology that is likely to go wrong, have a flat battery or just break.
We shouldn't ignore the trouser-staining possibility that it 'splashed down' first.
The Paperwhite costs £10 more than the Kobo Glo which has the same screen resolution but doesn't come with adverts.
'Moreover, big name foreign tech firms such as IBM also have such committees in their China businesses, according to Tea Leaf Nation.'
I'd love to see the reaction of fascist-loving IBM founder, Thomas J Watson, to the news that the company has communist committees.
'REALLY? SO these accounts, filed at company house, should not be used to draw conclusions about the fiscal performance???'
They should be running a train company.
As opposed to Dublin, Slovakia? Please don't go down the American route of assuming the readers know nothing of geography.
Solar thermal is currently more expensive than photovoltaic, but it does have an advantage that heat can be stored in molten salt so it continues to generate through the night.
'And while we are on the topic of Nokia: what the f*ck were they thinking when they did this.'
Wow! That's even more WTF than the 3650 with the circular keypad which I thought represented the apogee of magic nose dust design.
It can - you just have to search for Iceland.
'It has been used in video games for a fair while too... first, IIRC, on a Playstation racing game.'
I think it was 'Jet Set Radio' (fond memories) on Dreamcast that got there first.
Well that's the difference between good old British lets-give-it-a-go and teutonic thoroughness. Works for balloons - less well for the car industry.
It's also worth pointing out he posted them in a group set up for people concerned about the case. He went in with the intent to troll and cause offence.
Keep on hula hooping Grace...
There's also a blink-and-you'll-miss-him appearance by her then boyfriend Dolph Lundgren in AVTAK. My oh my I bet they were an interesting couple.
That much at least was based on serious engineering proposals made in the 1960s. The idea being if you pump water into fault zones you can increase the pore pressure in the rocks to a point where they overcome the sticking pressure holding the fault closed. If you could control the pressure you might be able to allow the fault to move gradually rather than in one catastrophic jolt.
It was planned to deploy it around Los Angeles where the San Andreas fault group makes a near 90 degree turn and is locked in place by the northwards movement of the Pacific plate. There have been no large 'quakes in the area in most of historic times, so the fault is under enormous pressure.
The real problem is that we don't know nearly enough about how faults break. Generally when one part of a fault breaks it transfers some of its energy into adjacent sectors of the fault, if they were close to breaking you could trigger another earthquake. So the liability issues are huge.
Also, the number of 'quakes needed to destress a fault would be massive - you'd need tens of thousands of smaller shocks to produce as much energy as is probably already accumulated in the San Andreas near LA.
The theory came about because a link was noticed between the frequency of earthquakes in Colorado and the pumping of nerve gas wastes down a deep borehole. As more liquid went down, the frequency went up. We see the same correlation around geothermal power plants which return spent well water to the reservoir, in some oil and gas fields where fluids are injected to recover more produce, and around large reservoirs where water is being forced into faultlines.
There was some research in the 1950s into so-called salted bombs in which the shell of the bomb is turned into radioactive isotopes by neutron bombardment and is then spread on the wind. Several elements have been proposed one of which was gold 198 with a 2 day half-life.
The most famous salted bomb is the cobalt bomb which used a cobalt 59 shell to produce cobalt 60 which accumulates in the bones. It is a beta emitter, whose product is nickel 60 that spits out gamma rays. The UK tested at least one device in Australia to prove the principle (it works), but AFAIK no one ever put the bombs into service.
Ah come on, let's not dillydally round with mirrors.
Just fit every plane with a laser guided missile (pocket edition).
A nice lump of plutonium would keep the whole thing warm indefinitely and you'd easily find it afterwards. You should ask BNFL if they could lend you a chunk.
Seriously, what's the worst that could happen?
Before purveying fiction for the government, he was an author of soft-core porn including the immortal 'Busking with Bagpipes', which includes such immortal lines as:
'a little known aphrodisiac - the dangling pipes of Scotland...It's all tongues and teeth, lips and gentle squeezes... As I lie on a Lisbon hotel bed next to a Portuguese person crying out for more, I thank my pipes for doing most of the chatting up.'
A crime against good writing surely, but much less damaging than his subsequent career.
From the money he earned as a presenter for that bastion for freedom of expression 'Russia Today'?
'There is buried Turing treasure somewhere!!!?'
It's probably under Milton Keynes. You might do the world a failure by digging the place up.
The scariest hands in all dinosaurdom?
Despite the Freddy Kruger tribute act, Therizinosaurus was almost certainly a herbivore
They do seem to be missing a shed.
Although 'hardened bunker' might just qualify if they put some flowerpots outside.
Ah they were a fantastic band.
'keeps tabs on whole population'
Thanks for clearing that up - I was wondering what a 'Facebook research centre' was.
"The nitrogen is transported with air currents and reaches the ground in rain or snow."
They are referring to nitrogen compounds such as ammonia or nitric acid which are available for plant growth rather than molecular nitrogen.
It's only 25 years since Mosfellsbær received a municipal charter and became a town in its own regard. Having said that, it's pretty much submerged in all the meh suburbs and industry of the Greater Reykjavik area.
It's not a dumb question.
There's a theory that atomic nuclei contain shells of particles akin to the shells of electrons which convey their chemical properties. As the shells in the nucleus fill up the atom should become more stable and will have a longer halflife than those with only partially filled shells.
This is why it is believed that heavier elements round about 120 will start showing longer half lives and form an 'island of stability'. Some of these elements might have half lives measured in years or even millions of years, so they might have some use.
There's also an interesting chemical question that these new elements should obey the rules of the Groups to which they belong. For instance element 117 (provisionally ununseptium) belongs to Group 17 - the halogens; whilst 118 (temporarily called ununoctium) *should* belong to Group 18 in the periodic table - the Noble gases. If these elements don't obey the rules predicted by their position in the Periodic Table then our understanding of the elements will need to be revised. And that is Nobel Prize territory.
Will the Chinese claim it?
Am I dreadfully out of date in not having a clue what that means?
And what the participants got up to after they got back to Germany (slight spoiler - not a happy ending).
