Is this just a repeat of your last thread ?

I fully admit I am far from an expert in this subject. But it seems to me that those who are much more expert than I am have yet to fully explore and understand the situation. This conference article in SCIAM is most interesting. In particular it seems that many definitions have been changing rapidly these days, particularly in the light of new chemical and biological discoveries. The article also discusses the medical implications of the subject. https://www.scientificamerican.com/article/q-a-mixed-sex-biology/

I consider jumping to conclusions without ascertaining the facts, to be pretty poor Science.

I'm sorry I don't understand this. I was pointing out that Switzerland never has been mono-ethnic. In order to be helpful I listed the principle ethnicities. Ethnicity type 3.2 French origins. Ethnicity type 3.3 Western European or 3.4 Northern European origins. (German) Ethnicity type 3.6 Southern European Origins.

Well I disagree. Last time I was in Switzerland, it was still divided 3 ways between the French sector, the German sector and the Italian sector. Maybe divided and sector are a bit strong but certainly there are three distinct cultures. I remember catching the overnight train from Freiburg (in Germany). The same conductor woke me in German, later offered me coffee Italian and when he walked back up the train checking tickets he did so in French as we headed for Geneva.

Perhaps you might think a bit harder before you post ? You might then be able to address the things I did say, rather than the things I didn't.

Yes and I mentioned a few cases and....? Totally agree. If The English establishment had not treated the Irish so badly over several centuries we would still be one country. But then the English establishment treated the English, along with everyone else, just as badly. Genoncide implies a deliberate murder in an attempt to exterminate. (Daleks ahoy) Indifference is quite a another matter.

Outside the USA ?

From the rest of your post I assume you are a US citizen. I think you are overdramatising the situation, partly by ignoring substantial parts of your own History, and like the OP, partly by confusing racial (the stated) subject of this thread with tribal and with personal discrimination. For instance I see no mention of the purchase of Alaska or the creation of the Indian Territories. There was no genocide. There certainly was tribal and personal discrimination that led to major hardship including starvation. This also happened in England. (Who were 'the Bits' by the way ? My family suffered as much under the same regime, but in mostly England and Wales.) Thank you for this reply to my post you quoted. I'm sorry but I can't see any connection to what I said ? Of course Science cannot do 'everything' That is why we have the Arts, Humanities, Sports Gardening and many other activities. It should be noted that Science can offer matters of note to enhance these subjects. I am unclear if this thread is meant to be about genocide alone or to include lesser forms of discrimination. It is a huge topic so I will leave a few examples of racial and tribal genocide and a mixed version of religous genocide to illustrate the difference. I am not aware of any personally inspired genocide, such activity tends to be limited to lesser discrimination. Racial Genocide: Carthage, Nazi jewish programme, Uighers Tribal Genocide: Ruanda Religeous Genocide: Cathars , Inquisition, Yugoslavia

About the greyness, I would agree with you, but what makes you think Science does not offer a multitude of approaches ? For example in considering a structure you can use Force-Displacement, Slope-Deflection, Virtual Work, Energy theorems, Graphical methods, finite elements, and quite a few more besides. But surely the issue here is that Politics at SF is whatever the powers that be deem it to be ?

Good, I can reply to both of you at once. In 1968, my hall warden at uni was head of 'Political Science' - whatever that was it was far more than statistics - but not really my subject, though I had my opinions like most callow youths of any generation. But surely here the subject should be more than just venting opinions ? And no I was not pointing the finger at anyone in particular.

I wonder, have you been following the discussion with another member about the geometric interpretation embodied in Minkowski ? Why is the time axis in a space-time diagram a distance - Relativity - Science Forums Relativity without time dilation or length contraction ? That is Galilean or Newtonian relativity. The thread I linked to has got as far as that. The problem with Galilean relativity and why it had to be abandoned , except at low speeds and locally, some of its predictions are in direct conflict with observations that late nineteenth century scientists made and subsequently more recent scientists have made to much greater precision. It is too long to reproduce here but I can email an English translation of the paper delivered to the 80th assembly of the German Natural Scientists and Physicians at Cologne in 1908, by H Minkowski, shortly before his untimely early death from appendicitis. If you want a scan of the paper, let me have an email address that can accept jpgs of up 1M by private message. I would recommend reading the paper as I think you would find it accessible (ie not too mathematical or high powered, no offence) he was a natural at explaining his points.

I'm sorry, where is the SCIENCE in all this ? Forgive me, but I thought the rules here state that the politics subforum is for the discussion of scientific aspects of politics.

How does this work out with world vectors ? Minkowski was (is) famous for developing geometric solutions and explanations to mechanics / and dynamics problems (not only relativity), so departing from his 1908 presentation requires a lot of thought. In particular you can express Maxwellian vector electrodynamics directly in Minkowski's geometric representation, the vectors and especially vector-products, which still work using four-vectors. Note the c is conventionally lower case. It is not a good idea to start by choosing new and unusual symbols for something everyone agrees on. Particularly as Einstein's paper was entitled "On the electrodynamics of moving bodies" As such it was about marrying Newton and Maxwell (metaphorically). And, of course, C is used conventionally for the electric field and the quantity capacitance.

Out of interest here is an example calculation I was recently sent for a much larger heat pump for a commercial building installation.

There's an unjustifed jump to a conclusion right there. Who or what the hell is FDA and what does reporting the FDA have to do with the price of bacon ?

I felt that the video, whilst strictly correct in one sense, was disingenuously hiding some things, whilst making too much of a meal of others. In this respect and bearing in mind @Phi for All's recent comment favouring the written word over videos: References to a transatlantic telegraph cable bears little relation to the working of a power supply cable and could have been omitted. It was unjustifiable showmanship. Whilst they did say that the battery and the light were 1 metre apart, they di nothing to bring that out, except at the end in a smart alec, aren't we clever kind of way. They failed to mention the fact that the disparity in the length of the supply and return conductors was so large at 1 : 300,000,000. I can't think of any normal power supply connections with such a ratio. Much closer to 1 : 1 would be the norm. So an interesting bit of electrophysics would have been to analyse for two cases, the one they showed and one with both conductors at 300,000,000 metres in length. All in all I prefer the more measured discussion of the topic by Francis Sears (MIT) in his famous book 'Electricity and Magnetism'. Francis also make very clear the distinction between potential and emf.

There was no failure in my case. That is my point. The metal mechanism of the punch has a soft plastic catch plate for the punched paper disks that is fitted underneath by stretching it slight over the base of the metal frame. Clearly it had to be only stretched in the elastic region or it would not the snap back into position, gripping the frame. Taking it into the plastic region would result in a permanent set so it no longer gripped its place tightly. I was simply reflecting on how many plastic cases of many items and gadgets these days rely on this.

Thank you for your response. Yes I can confirm that all three incidents were pretty immediate following rhe shot. (Isn't that what happens in anaphalaxis as opposed to any old reaction ?) UK innoculation staff are all trained to watch for and be able to deal with any reaction followng the origninal Dumfries case. Of course I should have specified adverse reaction, after all we all hope to have some (favourable) response to the shot. I had no personally detectable response to my first two shots, but on the most recent third (booster) i had no response before I went to bed the night of the shot but has a slightly sore area on my arm at the innoculation site the following morning. This faded over the following couple of days. The actual reports are numerically exact but not gained from the covid monitoring programme but from the hospital's own incident (of any sort) monitoring programme. Every reportable incident is reviewed, categorized and catalogued for any appropriate follow up action.

As I was refitting the soft plastic debris catch plate to my hole punch, I reflected how often we use and rely on the elastic properties of so called plastic materials. If they genuinely operated as a plastic material there would be instant failure of the component. Comments ?

Thank you for response, which was even briefer than my original post. Since you wre the only one interested enough to respond at all +1. However you have jumped to some unjustifiable conclusions in your response, particularly as to the source of my information and the phrase "promptly and successfully treated" , which was indeed absolute and correct, rather than an overly-favourable speculation.

1) Is there a wheel lock and if so is it unintentionally engaged ? 2) Since you can detach the wheel, is there any relative movement or 'backlash' at all between the two moving parts ? 3) You might be able to free it up by spraying with silicone dry lubricant and hand twisting the two parts back and fore. 4) Are all the wheels locked or just some ?

For those that might be interested. In the area covered by our local district hospital they have now administerd about 245,000 covid vaccinations, mostly Pfizer with some AZ and lately some Moderna. In they started this in January 2020 and since then there have been 3 anaphalactic like reactions, none with serious lasting effects. Of these one proved to be actually an epileptic episode, that would likely have happened anyway and nothing to do with the vaccination. The other two were promptly and successfully dealt with by the attendant medical staff.

Not at all sure what this question is about, but usage varies quite considrably over Europe. The reaction of the sales person to the question cheque, cash, credit or debit or charge card, phone has several complex factor and so varies considerably. Perhaps the most important is whether you are dealing with a large organisation or a small trader. Many employees of large concerns can't be bothered to implement anything that requires a decision or extra work for themselves, even if they have the authority. Flash the card of the phone, job done, no work for them. On the other hand small concerns used to be more receptive to offering a discount for not using a credit card. I have a personal policy of offering a small trader the choice of, whichever is cheapest for them, to try to support local business of multinationals. Until recently they usually preferred cash, but changes to banking charges mean that many now find it cheaper to ask for a credit or debit card (some find one card cheaper, some another it just depends upon their bank). But just this week Amazon has announced it is ceasing accepting credit cards, due to high fees (0.1%) has been mentioned for them. In the UK people have accepted all these forms quickly and readily, as they did in the Netherlands. Recently I had no problems on a bus in the Netherlands buying a bus ticket with a credit or debit card, but in many places in the UK you need a phone or a special charge card for your bus ticket. But the first time I visited my friends in Germany I was suprised that the Germans disklike credit cards and not many places accept them, though more so do now. It was explained to me that antagonism towards any form of credit is deeply ingrained in the post hyperinflation german psyche. Ireland is pretty similar to the UK. France and Spain are somewhere in the middle between UK and Germany. Italy is similar to Ireland.

Actually you can, but only if you try some theologians who are also real physicists. Such as Michael Heller John Polkinghorne KBE. Not the twaddle from this member who seems to want to outdo Trump with his tweets.
