        British foreign policy was aimed at making sure no European alliance got too strong in comparison to any of the others - while doing as little as possible. So that Britain could float down the river in splendid isolation occasionally sticking out a paddle to steer (to misquote Lord Salisbury ten years later).

            Re: amazing...

            That would be a rather odd view of history. Settling a war with a royal marriage had gone out of fashion a hundred years before. The politicians had started becoming the main movers of European history in the 18th Century - a process that was accelerated by the Napolenoic wars and especially the revolutions of 1848.

            Only the Tsar was fully in control of government by WWI - and the Russians were considered to be out of date, or even backward. Kaiser Bill was one of the reasons the war happened, but he also wussed out at the last minute and tried to avoid, then limit, German mobilisation in order to avoid fighting on two fronts. Had he been fully in charge, he might even have stopped the war - although equally he might have changed his mind again.

            France was a republic, and the British royal family had influence, but little actual power. Edward VII did quite a bit of the spadework for the entente with France - but that was as a diplomatic schmoozer, not the architect of the policy. He was sent to do it.

      Re: Acceptable?

      I think it should be pointed out that we weren't really arming Johnny-Prussian in 1914. Although there were a few embarassing things that it turned out only they supplied (when they suddenly stopped), such as khaki dye for uniforms. Admittedly almost everybody else who had dreadnoughts seems to have got them from us, such as Austria-Hungary (so good they named it twice).

      So it wasn't so much the arms dealers, as the governments buying so many that caused that. Plus a horrible miscalculation on what modern war would be like. And a German (and Austro-Hungarian) political leadership who were both hilariously incompetent and dangerously belligerant. With dishonourable mentions to the pisspoor diplomacy of Grey for Britain and the Russians.

      On the other hand, Britain did rather insist on its right to arm the South in the US Civil War - because just because they were fighting to retain slavery was no reason not to take their money obviously...

        I believe that according to Christopher Clark one driver of WW1 was actually the French banks,who loaned lots of money to the Russians and Serbs to buy arms (made in France), and then when they couldn't afford the repayments suggested that a nice little war might loot enough of Austro-Hungary to pay the instalments.

        But, armaments makers and the politicians they buy with the proceeds do seem to be the main cause of modern wars. The key driver is that you have to sell arms to foreigners to get the balance of payments right.

          That doesn't tally with the history of WWI as I learned it. Though I admit my knowledge is 20 years out of date, so new sources may have been discovered.

          But it wasn't Serbia and Russia pushing for war. It was Austria-Hungary and Germany. I believe the Serb nationalists who killed Archy Duke did have links to the Serbian army - but it wasn't an authorised/planned operation, and Russia were certainly not in a position to give immediate support.

          Also the Russian army simply didn't have any plans for war with Austria-Hungary that didn't also involve fighting Germany as well. As the Tsar found out when he ordered a partial mobilisation (only the units on the Austria-Hungary border) and it turned out they couldn't do it after 3 days of trying and had to fully mobilise.

          That military planning inflexibility was part of the cause of the war. The Kaiser found the same thing when he tried to change his mobilisation to only being on the Eastern border and avoid threatening France.

          My understanding was that Austria-Hungary were being reckless, because Germany had given them guarantees of support. And that the German military were pushing for action because Russian military reforms and rearmament meant that they expected the Russian military to be much more effective by about 1916.

          The Schlieffen plan had already been updated to move forces from the French border to the Russian, because the Russian army were more effective and faster mobilising than they had been ten years before. And the German military were horrified by the idea of a two front war, hence wanting to knock France out quickly - which is why they only had 8 corps (16 divisions) in Poland to stop the Russian army and 7 armies (over 100 divisions) on the French border. And why the plan demanded the invasion of Belgium - despite the risk that would bring Britain into the war - as it was the only way to get room for a knock-out blow on France.

      Possibly more than anywhere else on earth, Tyneside was the cradle of early engineering and the industrial revolution, with railways originally being called Tyneside Roads.

It felt positively futuristic and idealistic compared to the morbid dystopian reality going on outside the grounds.

I don't believe any proof ever emerged. Irish special forces were employed along the border with NI after an outbreak in Country Louth, to snipe wild animals such as deer that could carry the disease across, with their national herd counting for a much more significant proportion of their GDP.

    Also of note to anyone wanting to visit Armstrong-related sites is Jesmond Dene and the adjacent Armstrong Bridge in the Jesmond/Heaton suburbs of Newcastle - the Dene was landscaped by the Armstrongs as their private gardens and later donated to the city, and the bridge is a rather fine example of early ironwork. Meanwhile, in the heart of the city down on the river you'll find another of Armstrong's creations, the Swing Bridge. Not quite as internationally renowned as Tower Bridge, but it holds a special place in the hearts of locals.

      I believe the swing bridge is still powered using the original equipment installed by Armstrong's company, although it's much rarer for it to swing these days.

    turning the lamp off would mean lifting an electrified vase

    Two thoughts:

    the vase would be the return side of the circuit, so there may well be zero potential between the floor you're standing on and the vase you're lifting.

    a gentleman does not extinguish his own lamps, the butler would extinguish the lamp, and any decent butler would be wearing (nonconductive) gloves.

      More likely - though I don't know for sure - the system was probably ground-isolated. A reason mains is dangerous is that the "neutral" is earthed, at least at the transformer and in some systems at multiple locations between there and your house. Therefore it's possible for your body to short out the "live" to earth and create a return path. If the conductor is not earthed, there's no return path unless you happen to hold both conductors at the same time.

      We had a similar discussion regarding shaver sockets recently.

      Free Mercury though, with current flowing through probably causing it to heat up?

        A pool of mercury with a wire in it is a very low resistance source. it's also a good heat conductor so you aren't going to heat it up noticeably.

        Mercury at room temperature has bugger-all (ISO unit) vapour pressure and its health risks are wildly over blown (organic mercury compounds on the other hand are real fsckers)

      "This was a time before health and safety laws." Heh.

      Arc lamps have another property: they generate scads of UV. Which is not particularly good for eyes and skin.

      However, props to Armstrong for being an "Early Adopter", and for knowing how to live the good life. You just can't get good help anymore, and perhaps, overall, that's a good thing. But it's fun to pretend, just for a while. And good to preserve some relics of the old way of life.

    IIRC British neurologist Oliver Sacks - in his autobiography "Uncle Tungsten" - mentions that his relative had a lucrative patent on tungsten filaments for incandescent light bulbs.

    The Armstrong Disappearing Gun

    For anyone on the other side of the world there is another of Armstrong's products near Dunedin in New Zealand. In response to an 1886 scare about an invasion by the Russians they installed a "disappearing gun" at Taiaroa Head, at the end of the Otago Peninsula (there are a few others that are since lost). It is held just underground with a set of gas springs that will push it up in order to fire. The recoil will then push it back into its hidden position.

    One for the Geek's Guide to New Zealand, maybe....

    See https://en.wikipedia.org/wiki/Disappearing_gun.

    This is the one I've visited. I note from the wikipedia article that there are others in various locations, some in working order - the one at Taiaroa Head isn't.

      Why is anyone surprised that a bunch of disappearing guns have been lost?

    Nerds only toil for the sake of creation?

    “But Armstrong was no nerd, toiling for the sake of creation: his inventions were intended to simply make Cragside work better and ..”

    A nerd is by definition someone who wants to make things work better and there would be quite a few hanging round here.

    Cragside, worth multiple visits

    With Family in the area I have visited the house a number of times. Recommended! Can get very busy. Rhododendron time is special.

    Tip: At £19 per adult it’s pricey. If you are an Aussie National Trust member you get free entry under reciprocal rights. Minimum membership time applies.

      Ditto for National Trust Scotland members and other too.

      (I'll also mention, for anyone local enough to be on a day trip or staying self catering, there is an excellent, award winning butchers in Rothbury. Apart from the usual selection of meats being good quality, thay can also sell you zebra steaks, wild boar, ostrich, reindeer etc. (I still can't get my wife to try that last though. Probably because I insist on calling them Bambi Burgers - all the more for meeeeeee!))

      Re: Cragside, worth multiple visits

      Quite a lot of similar organisations have reciprocal arrangements. English Heritage has one with Cadw (the Welsh equivalent) so you can get into each others' castles at free or reduced rates. The Museums Association has an interesting one where employees of MA member institutions (as well as individual members) get in free to other MA member institutions, though this only applies to the employee themselves and not to family. Also many museums are free entry anyway these days :-)

        Does this explain how Edward I managed it?

        Walks up to portculllis. "Yep, there's 1,000 of us and we're all English Heritage members, so should get in free. We'll have the afternoon tea later though... What? Those 2,000 scruffy guys over there with the bows? Oh they're our butlers."

    Wot, no Escape?

    Disappointed the article didn't mention the place was shown on the premier UK television documentary Escape to the Country, which (along with crime documentary Midsomer Murders) is how most people in the US learn anything about the UK. (Obviously the Harry Potter media extravaganza is no help, since it is an utter fiction.)

    Escape did a bit on Seahouses, too, as mentioned in the first comments thread.
