  • Commented on Starship bloopers
    Nancy, One of the only countries in the EU that's still growing is France; maybe we should look at what they're doing to support families? Though it's equally possible that there are cultural reasons that it has a higher birth...
  • Commented on A death in the Firm
    Nancy asks: "Has anyone been tracking the Chinese and/or Russian vaccines?" Yes. Both have a low efficacy -- meaning as you say -- the vaccinated have much lower protection than those using other vaccines. (I get my second dose of...
  • Commented on Official Announcement: April Fools Day is Cancelled
    Ioan writes (326): Right now, 2 nm is still in the prototype stage. Some labs have built a 1 nm transistor, but I'm not sure how practical it is? GLENDOWER I can call spirits from the vasty deep. HOTSPUR Why,...
  • Commented on Official Announcement: April Fools Day is Cancelled
    "But actually Coates doesn't have to parody Peterson's ideas -- the Red Skull just quotes Peterson, no parody is needed." Don't you just hate it when someone quotes your exact words and makes you look like a complete plonker?...
  • Commented on Official Announcement: April Fools Day is Cancelled
    Since this thread started with April Fools' Day, now might be a good time to link to an amusing article in the Guardian: https://www.theguardian.com/books/2021/apr/07/jordan-peterson-shocked-by-captain-america-villain-espousing-10-rules-for-life...
  • Commented on Lying to the ghost in the machine
    Thanks. Yes, that discussion indicates that I may have something to get my teeth into, but what I need is a killer reference for a judicial review (yes, seriously) and an inquiry. Well that sets my mind at rest. I...
  • Commented on Official Announcement: April Fools Day is Cancelled
    (PS: Toby Young could not be contacted for comment.) Who? (Link for those lucky enough not to understand the final line of Charlie's comment. https://www.theguardian.com/commentisfree/2021/jan/15/waves-britain-lockdown-sceptics-crisis-government#comment-146733310 )...

    EC #1452 A discussion -- again in the modelling webpages, though I think a number of the participants are rail professionals gives this: https://www.rmweb.co.uk/community/index.php?/topic/49010-prototype-curves-how-sharp-is-sharp/ A quick squint at google maps suggests that your curve in Cambridge (at Coldham's Lane Bridge,...

    EC #1440 The following comes from the "olden days" before continuously-welded flat-bottomed rail. So, in "bull-head rail" -- as used between about 1890 and 1945 (approximately) we have the following turnout constructions: http://www.s-scale.org.uk/turnout.htm (Sorry, this is from a model society,...
  • Commented on Lying to the ghost in the machine
    You probably don't know this, but the National Secular Society have been trying to put a stop to that particular primitive act of superstition for many years now & are still getting shouts of "discrimination" & all sorts of irrelevant...

    The other big difference between Roman slavery and later versions is that the condition of slavery was not hereditary....
  • Commented on Lying to the ghost in the machine
    Hi Allen, Yes you caught me between thoughts. Initially, I'd thought about decelerating into the next system using something like Charlie's suggestion in Accelerando, but then I thought: "What's the odds of the next system being sufficiently interesting or amenable...
  • Commented on Lying to the ghost in the machine
    Frank, Your space ship problem got me thinking about how we could do it today. Obviously you'd send out baked-bean can sized star-wisp machines, but what would their mission be? Could I suggest you'd want to explore the solar systems...
  • Commented on Lying to the ghost in the machine
    I think you might be a little out with your scales. Nanotech -- dealing with "things" on the nanometre scale -- must really be about manipulating atoms. For example the atom spacing in crystalline silicon is about 0.25nm. And for...
  • Commented on Lying to the ghost in the machine
    Sorry Barry, I should have explained things better. Here in the UK the tariff for murder runs from a suspended sentence through to a "whole life tariff". From an average 600-odd homocides a year we currently have a handful of...
  • Commented on Lying to the ghost in the machine
    The death penalty is inherently cruel: even if you can carry it out painlessly, firstly the justice system has a non-zero false positive rate, and secondly, consider the (definitely not guilty) family members of the murderer who are being permanently...
  • Commented on Central Banking on Mars!
    Mike, Greg, Just to say, things here in Manchester are also running smoothly, vaccine-wise. Received text message from my GP on Tuesday; logged into booking website (needed my NHS number, which I had to ask the GP receptionist about); went...
  • Commented on Central Banking on Mars!
    A nice summary, Paul. To which I would add that here in the UK very little attention is paid to BATNAs by our politicians. Or indeed any other results from Game Theory, like Shapley non-zero sum games. David Cameron had...
  • Commented on Central Banking on Mars!
    What you need to know about US health spending is that the last time I looked, about fifty per cent is spent in the final two weeks of life. The outcome in my Mum's case was never in doubt, it...
  • Commented on Central Banking on Mars!
    But what about actual malpractice? That article stresses that doctors are "also human", so obviously some of them would be incompetent. Some of them would do wrong & harm patients. How does the U.K. system deal with that? Here's my...
  • Commented on Central Banking on Mars!
    LAvery, You need to be more careful in your definition of Θ(x). ;) Are we talking about Def.1 Θ : ℝ → ℝ ? Or Def.2 Θ : ℝ-{0} → ℝ ? Using the first definition, the function is not...
  • Commented on Central Banking on Mars!
    Actually, I've been thinking about this a bit since I raised the issue (@134). There is a cop-out available to many. Set theory controversies really only arise for infinite sets. (E.g., the axiom of choice can be proved for finite...
  • Commented on Central Banking on Mars!
    I think you somewhat overstate the case here. It is true, I think, that the vast majority of mathematicians use, or at least recognize, the same toolkit. The very term "non-standard logic" gives it away! It wouldn't make sense if...
  • Commented on Central Banking on Mars!
    Greg, icehawk Cobblers. SOME of Mathematics is clearly real. It produces unequivocal results, no matter which number-base you are using, makes correct predictions & describes aspects of the world(s). If you search the thread you'll find my answer to this...
  • Commented on Central Banking on Mars!
    Whitroth: first great to see you back on here; I very much appreciate your comments. You write: Yesterday, the PT (physical terrorist) walked me all the way down the hall, up to the landing and down, 10 steps, then partway...
  • Commented on Central Banking on Mars!
    Elderly Cynic says: "Actually, I find real numbers very easy to understand (as I do measure theory)! But that was only when I stopped thinking in terms of values that I (personally) could see how to construct, and thinking in...
  • Commented on Central Banking on Mars!
    Greg asks: "However - see LAvery: the way they allow the creation of a sort of mathematical alternative universe OK - AND - in THIS universe? Is Maths "real" - & thus discovered in this universe, or is it invented?"...
  • Commented on A Quick Infomercial
    "With a cricket ball, that would be suicidal for anyone who can't track moving objects with their eyes. And I mean that literally; baseballs are a lot softer but, even with them, that's a recipe for losing an eye." Oh,...
  • Commented on What happens now?
    There's an M-2 .50 cal machine gun and an M-60 machine gun, but I've never heard of a M-50 machine gun. An M-50 Machine gun is one that is travelling the fastest (non-helicopter) way possible between the SAS base at...
  • Commented on Dead Lies Dreaming: Spoilers
    Charlie writes: "Power: it's a log scale, and you don't need anything like as much energy as a locomotive to kill an enemy messily and instantly if you've got a precise lock on their C4/C5 vertebrae, as noted. Precision is...
