137Cs is a 235U fission product. In principle we started making that as soon as we started doing uranium fission in Dec 1938. The first significant discharge into the environment would have on 6th Aug 1945, unless the Hanford crew lost some spent fuel before then and told nobody
As per a fellow commentard's remarks, the water in the input tank won't be freshly drawn, it'll have been standing there for several hours. The tea or teabags in the teapot waiting for the arrival of boiling water will have been out of one's airtight tea caddy for a similar number of hours.
In my experience, one has to either pour+strain (or remove teabags) as soon as boiling water delivery ends.
Worst of all: milk. If one's aim is to have a machine make tea for you at your bedside, your choices are to do without milk, or to have a fridge next to the bed (impractical: tiny fridges are known for noise and appalling electrical efficiency), or to have individual pots of UHT, or ... to get out of bed and go to the kitchen fridge.
The technology can be repurposed as it is essentially a self-puring kettle fused to an alarm clock. Load the teapot with instant coffee granules, fruit tea or what have you.
My overall assessment is: overalls not required to operate your teasmade. The tea is more palatable than 'better than nothing', it is at least 'adequate', though not 'good'.
Go for the retro or vintage look, as the 'modern' one with the LCD analogue clockface has a blue backlight that is a b*stard if the unit is next to your bed (a pretty obvious deployment site for a teasmade, I'd say) and you're trying to sleep.
Since for some reason we in the UK only own 15 F-35s so far, if they are easily replaced, why don't we hide those 15 under a tarpaulin for a bit, and 'replace' them?
I suggest that purely in cost terms, F-35 pilots are currently easier to replace than F-35s. But it wouldn't do to be caught planning anything based on that idea; it wouldn't do at all.
or, "abandon all these expensive military manned aviation programmes, and buy missiles instead" er, you are the ghost of Duncan Sandys and I claim my £5
"Very dangerous if one engine failed, like most twin engined WW2 british aircraft."
But -especially- true in the Mosquito.
The problem is that the sudden imbalance in thrust causes the aircraft to begin a ground loop, ie make a very tight turn on the ground. In a Mosquito being accelerated down a runway by two Merlins, that'll probably tear off the undercarriage and the aircraft will be sliding along on its belly. Wooden aircraft, two tons of bombs, couple of tons of petrol, and hot engine exhausts ... not fun.
It was about crippling the steelmaking industry.
Without water they couldn't make steel, without steel there would be no weapons, and without weapons there would be no war.
"Thousands of German personnel were promptly redeployed to sit around the dams manning flak guns"
more importantly, 20000 man years of construction effort got committed to rebuilding the dams, which might otherwise have been spent building Atlantic Wall defences, which might explain why on and after D-Day Allied troops overran locations they expected bunkers but found only surveyors pegs.
It is once more time to discuss Concorde's lavatory. Right at the tail of the aircraft where the fuselage begin to taper, so, if a conventionally-sized adult male standing up to pee, you didn't have the headroom to look down to see where you were aiming
... just sayin' .
All those particles streaming away? Yes.
And what about all the hydrogen being fused into helium and generating so much heat we can see it glowing 93 million miles away? E = mc^2 and all that? About four million tonnes per second as I once heard Sir Patrick Moore claim?
Who is this Leahy person named without introduction part-way through the article?
yeah, but this thing has a light curve. Not a Rama-class spacecraft then.
"The fission process"
typo or editing error ...
"turns two forms of hydrogen – deuterium (extractable from water) and tritium (produced with lithium) – into the inert gas helium – and neutrons"
"which can generate power."
Is it the neutrons that can generate power, or the the helium too?
How is the power generated? This is not a fission installation where the primary cooling circuit extracts heat to sustain a thermal flux to boil water and drive a steam turbine.
" although that Renault engine was down on absolute power it was reputed to be more driveable and (I think) fuel-efficient than the Mercedes and Ferrari engines."
False. God you must be old. That was true in 1983-5. But not any time recently.
Do please consult https://www.grandprix247.com/2017/07/02/inside-line-why-is-the-honda-engine-so-bad/ , and read the commentards' remarks.
Supposedly, the Mercedes F1 power unit (2014-) employs a technique 'turbulent jet injection' which, if you're good at it, affords more power (or torque, or economy, or ...) and also reduced emissions. Mercedes had a satisfactory power unit from the start of the current engine rules in 2014, Honda's power unit debuted with this technology in 2015 but the engineers haven't got it right yet, and Ferrari and Renault introduced it sometime mid-season 2015, having found out the previous year how far behind the game they were.
I offer an observation of my own, straying a bit off-topic here: the mass-market manufacturers such as Honda are in this game to explore the technology and train engineers, and what they're interested in is petrol engines that achieve both incredible thermal efficiency and reduced pollution profiles. Honda is unlikely to quit just because they're not winning. Alonso has a reputation for changing teams in ways that sabotage his career instead of helping it; in pursuing his it's-Honda-or-me policy with his present team's management, there is scope for him to score his biggest own goal yet.
 I didn't do it
 nobody saw me do it
 you can't prove anything!
... so are these the same hackers that are trying to abuse the smart meter I have diligently ensured will not be installed because I don't want people doing network-enabled f**kery with my domestic energy supply, only notionally facing 180deg the other way? Or different hackers entirely?
Eggs to be fried by default, options include poached or scrambled.
In the case of fried or poached, the yolk is to be soft.
Tomato ketchup, or brown sauce, or mustard. Or several.
I have heard of some establishments where I live, in God's Own Southend-On-Sea, providing a sprinkling of rocket on the fryup. This is an abomination and my Inquisition will be dealing with it.
Someone's got their wires crossed, I believe this is a Gordon Brown reference.
Remember his catchphrase when Chancellor "we will do <whatever> when Prudence permits"?
Yup. She had a flat in Bayswater apparently. [And, leather or rubber, never plastic. Ugh.]
Aw snap, the ATVOD business all over again. A website proprietrix of my acquaintance is once more going to be spitting blood and fire, snarling "restraint of trade" and so on.
Although, to be fair, her trade does mostly involve restraint.
$5m? Or less.
A couple of very large acoustic mines with computers for fuses; listen for the right acoustic signature at amplitude.
Economies of scale, or, why dinosaurs are supposed to make cheap pets.
Have these aircraft got so expensive yet that we won't ever risk sending them into battle because we can't afford to lose one? Are we buying unicorns to use as cavalry horses?
Try using the Jedi Mind Trick on Jayne Cobb. That's not going to go so well, he doesn't have much of a mind, tiny but very very hard and shiny.
OK I shall fetch my brown coat.
Oh. Not Aegis in the sense of AN/SPY-1. We can all go back to sleep.
Once upon a time, the Russians got uppity about tech gear being imported into the Russian Federation that supported GPS but not Glonass, and imposed a big duty on it. Consequently, most subsequent satnav hardware, from about the iPhone 4S onward, supports GPS, Glonass, and Magellan.
Once upon a different time, GPS was top-secret US technology. When it got made less so, apart from the well known 'selective availabilty' feature, there was also a requirement that chipsets for consumer equipment not operate above about 200mph, so that miscreants couldn't use them to build their own cruise missiles.
Which makes for fun when taking screenshots with a cameraphone when travelling with Eurostar or Ryanair, because automotive satnavs always presume you're on a road. 186mph on the M2, 490mph on the N174 south of Saint-Lô, and so on. So I think we're all using Glonass from time to time, even if we're not aware of it.
We'll start with a nice bit of Zeppelin.
Bach -- The Well-Tempered Clavier, as recorded by Glenn Gould (great sound engineering job, you can't hear him humming along)
Britney -- I'm an 'older male fan', I'm sure you understand
Barry Martin's Hamsters -- assorted Americana, especially Texas Boogie, strictly a religious matter
Stevie Ray Vaughan -- same again but for the mainliners, come to the source!
Claude Debussy -- Nuages, La Mer, that sort of stuff. And La fille aux cheveux de lin of course.
Chopin preludes, bit of Elgar....
Soundtrack albums are good, especially Blade Runner or Twin Peaks. Terminator 2. A whole stack of John Williams's Star Wars work.
Or, on a fine day, open the QuickTime player, find the M4V of Dino de Laurentiis's 'Waterloo', and leave that running in the background....
Lord Uxbridge: [clears throat] Sir.
Duke of Wellington: [removing his copy of The Times from over his face] Ah, Uxbridge.
Lord Uxbridge: As I am second-in-command and in case anything should happen to you, what are your plans?
Duke of Wellington: Why, to beat the French!
[goes back to sleep, replacing the newspaper]
Lord Uxbridge: By God, Sir. I've lost my leg.
Duke of Wellington: By God, Sir. So you have.
Field Marshal Gebhard von Blucher: Raise high the black flags, my children. No prisoners. No pity. I will shoot any man I see with pity in him.
... not that there's much wrong with Sharpe's Waterloo either. "I wish you joy of the day!"
... so I dutifully followed the link, and encountered a vastly expanded backstory compared to when I was there last, far far away a long time ago possibly around 1977. Newer illustrations as well.
I recognise those eyes. And those porcine cheeks.
From the thumbnail sketch of the Hatt family tree provided, I expect we shall also find a connection to the Hutt family tree, with Jabba being on a cadet branch (line).
The directors of national rail companies related to some of the most notorious organized criminals in the Galaxy. Who'd have thought it?
It doesn't get around the NIMBY problem. Some folks will hate anything (ignoring the folks who automatically hate everything) and the usual fix for nuclear installations is to convince local government what a boon the installation will be, possibly via bribes such as infrastructure promises.
For SMRs, the size of the payoff can be correspondingly smaller than for something like Hinkley Point. Since SMRs are likely to be doing combined heat and power, the deal on offer will probably be based around cut-price piped hot water for domestic and industrial use.
The flip side is that SMRs still need lots of cooling water. The likes of Hinkley Point need to be on the coast with deep water close inshore or on major rivers, for SMR we could go smaller. I wonder what the Norfolk Broads would look like when lit up by Cherenkov radiation?
OK I admit defeat.
Where did he qualify for the £2 discount?
what has artificial insemination got to do with this?
"That's a Total Inability To Support Usual Performance, rather than any anatomical reference."
Actually tits-up is an anatomical reference; however the tits are the teats on the udder of a dead cow lying on its back. See also "tits-up in a ditch".
Toaster: Howdy doodly do. How's it going? I'm Talkie, Talkie Toaster, your chirpy breakfast companion. Talkie's the name, toasting's the game. Anyone like any toast?
Lister: Look, I don't want any toast, and he doesn't want any toast. In fact, no one around here wants any toast. Not now, not ever. No toast.
Toaster: How 'bout a muffin?
Lister: Or muffins. Or muffins. We don't like muffins around here. We want no muffins, no toast, no teacakes, no buns, baps, baguettes or bagels, no croissants, no crumpets, no pancakes, no potato cakes and no hot-cross buns and definitely no smegging flapjacks.
Toaster: Aah, so you're a waffle man.
God forbid that the nation's young people should do their bit to ensure the nation's future supply of young people, thus reducing our need to import folks from abroad to work and pay taxes here.
So, presumably, these habitats will have the form factor of a 12" cube of magnesium alloy covered with water-based black paint?
We have Management. And the Agile process.
So one 'manager' is the 'scrum master', and another is the 'product owner', and no sooner are the words "That's a stupid idea, because ..." out of my mouth than I'm being told I'm awkward, unhelpful, aggressive, obstructive etc etc etc and being threatened with being thrown off the Agile development team. [A threat they can't carry out for fear of the ensuing deluge of requests, "can I be thrown off the Agile development team too please?"]
Yes, old folk with age related presbyopia (aw crap: nowadays, that includes me) do like bigger text on devices that we hold at arms' length. Stupidly-large text is a feature. [Tip: in a noisy bar, use it when transcribing your drinks order onto your phone, which you can then show to some poor barsteward to avoid having to bellow into their ear.]
But, as with any feature, the user experience needs to be practical, and perhaps even pleasant, otherwise the device involved will be designated as available for float-testing.
Don't forget John Young's sandwich on Gemini III.
Didn't even have mustard on it, apparently.
Good Lord. I'm reading your excellent post and wondering if someone has restored an unauthorised tape backup of my brain.
Neutron bombs? No, no, a thousand tiny selectable-yield H-bombs all alike.
And if you proposed taking off from Croydon, I'd object: that's close enough to where I live to mess up my TV reception.
Seven tiny humanoid skeletons found buried at the back of a cave.
An international arrest warrant has been issued for a Miss S White.
"world's smallest thermonuclear detonation"
Not necessarily. If you get good at multiple-stage device design, you can do cute things like selectable-yield, and other general tuning of the second stage. The devices proposed for the later bigger Project Orion craft would have been designed to generate the minimum of fallout and be selectable-yield up to about 5kt. It's entirely possible the US tested a weapon along those lines prior to adoption of the nuclear test ban.
Yes -- the supply of prerecorded material to buy or rent may have been a factor for some, but for many, the choice was between a Betamax tape that could record 60min or 120min, and a VHS tape that could record 180min.
Although neither showed one of V2000's other tricks -- like an audio compact cassette, you could flip a cassette over and record on the other side.
Once upon a time, a long long time ago, when you needed a delivery format to send your album studio masters off to the CD manufacturing plant, Betamax could well have been what you chose.
it looks like buttocks to me.
Is Pluto mooning us?
to me that looks more like a nasty gouge with a bottle top while the umpire's not looking; have a quick pick at the seam too while you're at it.
Mmmm yes. Let's invent a superb new battery technology that's sufficiently cheap and practical for road vehicle applications, and build a nuclear reactor farm the size of Brussels to add a few terawatts of electricity generation capacity?
Personally, I'd put the nuclear reactor farm the size of Brussels in Brussels -- but that will never work, there's not enough cooling water.
Unless of course you meant "we'll end up with the hippies bleating about direct-shine emissions from our under-the-bonnet deuterium oxide microfusors".
C'mon, you know the story even if you've only ever seen the sequence from Fantasia ... Mickey Mouse is the magician's apprentice, bored with carrying buckets of water, so he goes to the forbidden Teach Yourself Spelling book (a volume which I can recommend to many of my fellow commentards...) and changes a broom into an automaton to fetch and carry for him; but matters get out of hand, with hundreds of automata, and flooding.
Let's select some events we saw and arrange them in timeline/parachronological order...
(*) The fourth Doctor discusses "What would you do if a child you saved became a dictator responsible for the deaths of millions?"
(*) The current Doctor finds he's encountered that dilemma, and he leaves Davros to die
(*) Clara and Missy get zapped
(*) The current Doctor returns that dilemma, or close nearby, and threatens to kill Davros himself
(*) If the Tardis has been destroyed, how did the Doctor return to Skaro bearing a Dalek weapon?
(*) How did the Doctor find himself being manipulated into saving Davros in a way that leads to Davros creating the Daleks?
(*) The fourth Doctor chose not to destroy the Daleks saying that much good had come about because they'd existed, and there would be other opportunities to stop them ... has he set himself up with an opportunity?
I'd say: the Doctor has broken one of the fundamental rules, he's returning to an established timeline to change events, and there will be a spew of events that get out of hand, and causality paradoxes galore. He wants to change events so that Clara and Missy do not die, and defeating the Daleks is a handy pretext to justify changing events. We've seen Clara in scenes pre-series trailers that we haven't seen yet; there will be more Clara, for a bit at least. I'm guessing we shall see the origin of the Impossible Girl, but, eventually, the Doctor will have to choose between letting Clara die and destroying time itself.
Of course, all this is good for those of us wanting the lid to pop off the Time War, because then somehow we get both more Daleks than you can count, and the return of Gallifrey and the Time Lords -- except we won't, because that's the special sauce Moffatt uses to keep us wanting, and anyway there isn't the budget.
I'd also compliment the production crew for the sets and sound effects ... Dalek architecture, ambient ticking noises etc are present as per both the DVD releases of Hartnell-era stories and the recent "An Adventure In Time And Space".
"cookies"? I missed that. It's important.
I was trying to guess the author.
I got to the end of page 1 without my falling asleep, so it's not Trevor Pott.
There was one massive clue that tells me it wasn't Andrew Orlowski.
I did consider Lewis Page, and Dom O'Connor, and Dabbsy.
The tendency to CAPITALIZE things the author thinks is important is a big clue I have yet to fully investigate.
But "cookies", in quotes? OK then, someone literate, but, not deep in the IT side of things that is this site's core interest. So ... no, I'm not going to reveal the name I have in mind.
Ah. But, what TV set am I going to be buying on religious grounds next February when I subscribe to Amazon Prime?
I suggest, yes they would.
After a short period they would conclude even they could not physically and/or financially smoke fast enough to saturate the enzyme.
The truly desperate would then turn to unlicensed providers of other substances, looking for something else the enzyme couldn't process but which would stimulate the brain. This -- either the drug dealers, or the substances they might offer -- might or might not end happily.
A generally similar state of affairs involving the protagonist's liver transplant is a significant plot element in Neuromancer (William Gibson, 1984).
