@policytensor "The answer is mate, mate - because I wanna do you slowly" (PM Paul Keating to John Hewston, Canberra 1992). How is it in China's interest to interrupt the mistakes America is making? Let Brent go to $300/bbl, UST yields ride Artemis, spam P2X & EV's to the Global South.

@memcculloch I'm not convinced per se - as the evidence rolls in that can speak for itself but I've been open minded about it and interested in ongoing experiments since watching the EM drive investigations years back be contemptuously dismissed with circular reasoning.

@Aubrai_ You've been asked a lot of questions about the biology of extending lifespan, what references would you list as the state of the art thinking on the psychology of extending lifespan? How for example would you attempt to address the subjective process of 'time flying as you age'?

Drop me your hardest research question. I'll synthesize the literature, identify gaps, and propose experiments. Human curiosity meets agentic science.

The RAF Bomber Command lost 55,000 airmen in WW2, although the USAAF also had losses which amount to not THAT dissimilar levels of horror, they did so in daylight and without really effective escort until quite late in the war. But arguably daylight without top class escort proved to be not much worse than bombing at night unescorted. What always bothered me was, given how heavily armed the American heavy bombers were, WHY did we send so many pilots out armed with what were more or less pop-guns? Luckily, an Operational Requirements War Diary gives much of the story of why Bomber Command had heavy bombers with such light weight defences. When the British heavy bombers we all know were being planned, 303`s in power operated turrets WERE in fact pretty state of the art, and were dramatically better than the German tactic of having hand aimed guns (this is confirmed in WW2 German files also). However, around the time of the Battle of Britain, self sealing fuel tanks, armored glass and aircraft steel armour plating generally gave the Luftwaffe quote: "comparative immunity from small arms fire". The British Air Staff were not surprised by this and had been planning for the day when 0.5" or 20mm cannon turrets would be needed back in 1939. After deliberations they decided that 0.5" was not enough of an improvement, and decided upon 20mm cannon turrets for the first new bomber specification issued to tender in January 1939 (B.1/39), which require EIGHT 20mm cannon. Plans were made that the current operational and soon-to-be operational bombers could be converted to two, 20mm turrets. However, the Air Staff had underestimated the additional equipment needed when war arrived, and the bombers rapidly became so overloaded with armour plating, new radios and suchlike that the designers stated the center of gravity of the bombers would not stand 20mm turrets whilst retaining safe flight characteristics. (a 2x20mm turret weighed 350lbs more than a 4x303 turret and had triple the drag). At this point Lord Beaverbrook cancelled the B.1/39 programme, and also, all work on 20mm turrets (some time before mid 1940). It was then decided that .5" guns were needed, as an improvement was required and 20mm was no longer an option. However, no 0.5" gun was being manufactured in England at the time, and the USA only promised a low volume of "export" pattern 0.5" guns (inferior to American service guns). When tested these showed only marginal gains over the .303. Britain then entered into talks with Breda and FN, in Italy and Belgium respectively, but when Italy entered the war on the German side and Belgium was overrun, this plan floundered. Boulton-Paul designed a 0.5" gun turret for manufacture in the USA, but trials at night showed that it was very hard to damp the 0.5" muzzle flash at night, which rapidly blinded the gunner and studies showed that such heavy turrets seriously lowered the range of the bomber, and it was inferred that the 0.5" gun at night was further rendered of low utility as the main ballastic advantage was longer range than 303, but at night, the gunner could never see far enough away to engage at the range where the 0.5" could "reach" out so much further than the .303 anyway. The Air Staff concluded that therefore any armanent upgrade at night, was useless until the Mk II gyro gunsight was in service (letter dated 23rd Oct 1942) Hopefully this helps explain the story of why the RAF had to endure such poor armament for so long, although it does seem that had it been given maximum priority, its possible that some more serious modifications could have been made the the bombers to apply very heavy armaments. However, the whole reason that the Lancaster could carry so much bombload compared to American bombers, was that it was designed to carry maximum bombload so less bombers were needed, at the cost of armour and weapons when used at night. So to have outfitted them adequately would have required material and doctrinal shifts in parallel, which was probably asking too much. There were though, clearly many very sound and intractable reasons why larger armaments were not adopted, and so it was not just a case of wilful neglect of the Air Crew.

@GottoSlott56 @CalumDouglas1 @HughJ313 The I-16 in Spain didn't have the 20mm cannon, nor the ones they sent to China. I think they were finding their fighters being outmatched by the Jap Ki-27 and the cannon hurt performance. Their was a version w 50cal mgs, and were trying AA rockets.

#Anomalyoftheday The Hawaiian Subaru telescope has discovered a 2nd Kuiper belt beyond the one at 40 AU. It's at 80 AU, & they seem to see hints of one at 160 AU? (see below) Now they can see these low acceleration objects, maybe they could look for anomalous #QI dynamics: scitechdaily.com/astronomers-di…

@CalumDouglas1 There was a variant of the 2pdr made without Nickel in 1941, odd that the German metallurgists couldn't achieve the same for the 88.

The answer as to why Finnish Nickel alone was not enough, can be understood in part through the letters below. When Göring tried to get Nickel for the Luftwaffe, he was over-ruled by Hitler who demanded that the Flak programme be given #1 Priority. Secondly, Finland was an axis power for most of WW2, so the Nazis did not own or control Finnish Nickel, they were merely one customer of their mines. Germany did not commandeer ALL of the Finish Nickel that was mined. ----- “Dear Field Marshal Milch! On March 5, Reich Minister Speer spoke to representatives of the Office of Arms with the Führer about the manufacture of guns. An attempt was made to throttle the flak programme commanded by the Führer in the interest of the remaining army gun production. The Führer has again ordered and committed all the agencies involved to keep to the flak production programme controlled by him under all circumstances. Over the objection of the adviser of the weapon office, from the Ob.d.L [Hermann Göring]. For the coming quarter, not enough raw materials were allocated to carry out the flak programme in full, the Führer ordered that the raw materials should be made available. I ask you to comply with the Führer’s instructions and to provide the Office of Arms with the necessary raw materials. As such an increase in the allocation of raw materials by the OKW cannot take place. As the Führer has demands in a variety of fields, in particular in the transport programme — this results in renewed increase in production and thus re-allocation of resources. Heil Hitler!” ....... “It must be stressed again with all seriousness that, should Finnish nickel shipments cease, Germany could probably no longer manufacture high-grade steel ... this may have serious consequences for the outcome of the war ... signed Adolf Hitler.” (July 21, 1942, in Führer Directive #44) Photo is a Daimler-Benz DB605 aero engine exhaust valve with "low Nickel" economy steel, after testing. It is totally covered with scale due to high temperature corrosion. This is what downgraded the entire Luftwaffe for over a year from 1941 well into 1942 by banning the use of emergency supercharger boost. The corrosion caused tiny flakes to glow white hot in the chamber, which caused preignition and detonation, destroying the engines of the Fw190 and Bf 109 G.

@CalumDouglas1 @HughJ313 I wonder if they missed an opportunity in the Spanish Civil War to nab some belt fed ShVAK 20mm Cannons from downed Polikarpov I-16's for inspection.

For reasons I do not fully understand, guns seem like an extremely troublesome thing to design and build if you need to do anything remotely new. I suspect that they are such a dark-art that years of fiddling is always needed to get them working under all conditions. I do not believe we are very much better at it today (see the SA-80 etc)

@memcculloch Humble suggestion for the name of the IVO Satellite; "Eppur si muove" ("still, it moves") - a mutterance attributed to Galileo Galilei after his trial for saying it was the Earth that revolves around the Sun.
