A good presentation, for those who already know some Physics. +1

Sorry I can't answer this question as I have no idea what 40/40 points etc means.

The following summary of rules and examples may help you here. Hydrogen is a good atom to follow because it has only one electron. Thus it can only ever loose 1 and reach the +1 oxidation number. Note that the text shares the electrons equally in the case of two bonded atoms being identical. Thus two hydrogen atoms in a hydrogen molecule have one each of the bonding pair. Therefore neither atom has lost or gained an electron so they both start of with an oxidation number of zero for an unbonded atom and continue at zero when bonded into a hydrogen molecule. Note this example was not in the text, but the rules I have used are.

I'm glad you could follow my rather terse note. +1 The point about binary choice is that right is then the same as good or it is not and wrong is then the same as bad or it is not. There is no partway. Another binary choice. The point about scales is that measurement on the scale can be reported as a range, it does not have to be a specific point. Ranges in turn permit a measure of overlap between two scales and two meaudring ranges on those scales from full to partial to zero. You can draw Venn type diagrams. The whole subject become infinitely richer.

One problem with the presentation I see is that both 'wrong / not wrong' and 'bad/not bad' are presented as one half of a binary choice. Presenting these as a scale would allow better analysis.

Here is an extract from an excellent modern data source about symtoms of Covid 19 in the long term that may be of interest. https://www.bbc.co.uk/news/health-54296223

It is not only a grid structure that exhibits this difficulty. And they can be replicated within the public sector as well. I do not have much information about the legal situation in the Americas, but in the UK there are several legal problems to overcome. For instance, Most roads in the UK are 'owned' by some public body, but the land the road sits on is owned by someone else. There are other complex arrangements in other European countries. We really ough to have imatfaal back to discuss this one. The UK does offer a mix of public and private road that can provide examples of all sorts of situations for case study.

This whole thread reminds me of Edward De Bono's Black Cylinder Experiment. Why did it topple over ?

OK so I see where you are coming from now. I can't do any more for a couple of days as I am preparing for a funeral. So my best suggestion is to get hold of a copy of Chemical Equilibrium Denbigh Cambridge University Press and read chapter 9 which is devoted to this. I can't post the whole chapter but here are the first 4 pages. Note the discussion of two different conventions in use.

Well perhaps you should if you really want to stay in bed with the French. Their version still does exist.

Thank you for being helpful. +1 I do use that facility occasionally. But I would much prefer if computer designer and programmers stopped forcing things I don't want down my throat and put their minds to creating facilities I do want, but can't have.

You said, "they didn't dismantly anything" so I asked if you though the CEGB (as an example of one of the organisations I listed) still existed.

So the CEGB still exists?

If I might make a suggestion From a personal point of view if I had to type out all that name every time i wanted to address you in a discussion I don't think I would do it very often. The name may be 'funky' or whatever, but is a real pain to others to use. Do you think your new handle is any better? +1 That's the way to do it.

You brought up 'the swiss' Decades back, successive Uk governments of both colours began the process of dismantlying UK heavy industry. The promise was that we should look at the swiss and stop making things of large mass but (relatively) low value. Instead we should convert to manufacture of high skill, high value items as the swiss do with watches. Sadly almost all that has happened is the dismantling of old staple industries, the dismantling/castration of all the high tech institutions that served industry and society and the breakup of those large state organisations that were big enough to play a part on the international stage. This had nothing to do with the EU or later Brexit, although I am sure they welcomed all this self harm by a competitor with open arms.

I don't follow you calculation. Where does the 55 come from ? do you mean a molecular mass of 55 ? So I dissolve 1/2 mole or 27.5g of J in 1 litre of water. So the molality would be [math]molality = \frac{{0.5}}{{1 + 0.0275}}mole/kg\;ofsolution = 0.486618mole/kg[/math] To obtain the molarity, we don't know the density of the solution, so the amounts will be slightly different. But since it is very dilute let us say that there is no change of volume on solution so we have 1 litre of solution. So the molarity is [math]molarity = 0.5/1 = 0.5mole/l[/math]

I didn't know the Falklands were either in the EU or near enough anybody els to have local discussions. Why would they ? Are you saying the Swiss model is not attractive?

Yes it's possible, they take longe to recharge and need recharging more often. Very often they can get rather warm. But before you accuse the batteries have you checked the condition of the terminals in the handset and the batteries? These may simply need a good clean to bright metal.

No, in fact I suggested exactly the opposite. But +1 for the rest of your post. That is not a given and need not necessarily happen. As has already been pointed out, the Swiss model has many points of attraction.

I don't recall the western nations either individually or under some collective intervening in Hungary or the Prague Spring, or the suppression of Solidarity in Poland. Would the say the Netherlands go to the aid of Greece if they had a conflict with Turkey? If we went to the aid of Australia, New Zealand, or Canada if they were attacked by an Asian power, would any European nation help us ? How many wars have the 'great' United Nations actually stopped or prevented in the first place?

There is, of course, no reason for it to be an 'either....or' situation. The BBC at the moment is showing a programme called 'The Repair Shop' Here people bring in interesting (usually old) worn or damaged objects for repair. The programme films the stages of the repair from the broken article to the finished result. The objects themselves come in a huge variety of things. 1920s cash register tills, a world war 2 leather carrying case from the Air Ministry containing the rewuirements for an RAF chaplain to carry round and provide Communion, Old toys, a victorian cast iron donations box for the Lifeboats, famous sporting trophys, old teddy bears........................... Anyway all sorts of skills are involved so each volunteer does part of the job. Carpentry, metalwork, ceramic and glasswork, leatherwork, sewing work, painting.................... Anyway although it is a team effort, each member of the team works alone and then hands their part on to the next member.

Here are some examples from my experience. If it's maximum money you want. I have a friend who started his business from my front room and became a millionaire. He said to me "If I work as an engineer (as part of a team) I can only make the wages of one engineer." "But if I supply engineers to many clients at a %, I am not limited by the wages of an engineer, just the number of engineers I can supply" On the other had in the late 1960s, an aircraft design company (Rotax) want to test the idea of teamwork with either a mix of specialists or groups of specialists of the same discipline. So they gave these groups the task of designing and producing a safe control for two wing pumps, A and B. The point was that the aircraft power supply was inadequate to start both pumps at the same time, although it could run both together once started. Most machinery is like this it takes more power to start them than to run them. The mechanical engineering group came up with a complicatd mechanical interlock between switch A and switch B. The electronic engineering group came up with a fancy digital circuit board electronic version. Both were tested by simultaneously jabbing both switches by hand. Both failed. The lone genius came up with a simple single two position switch labelled switch on A , switch on B. In the offshore oil industry it takes teamwork to move a laybarge or an oil rig. One is moved by a team of tender tugs shifting anchors and onboard winches, The other by towing with a team of tender tugs. However it takes a talented individual to set one of these tugs alongside an oilrig, laybarge or service jetty.

Not always as I said, in my personal experience.

I didn't say that peace has nothing to do with the EU, I said I (and many others) consider it the principal reason. Yes a much smaller EU maintained a peace, now there are borders and restrictions between various countries of the enlarged organisation and internal pressures are building up. Again I did not suggest any war would happen tomorrow or that it would be an external one. You have a point about Iraq, but it could also be looked at another way: we were silly enough to allow ourselves to be dragged into that one. Should the EU as a whole go to war, we could not opt out. You might like to read the book by Historian John Grainger The United Kingdom The Unification and Disintegration of Britain since AD 43 It is highly illuminating about the stories of the individual 4 entities, England, Scotland Ireland and Wales.

No. Teams sometimes work out well, but there was research back along to suggest that teams sometime fail because of their structure. The ultimate team is, of course the committee, have you heard about the committee and the camel?
