We are looking for a mattress for our spare room, its 1 and a half washing machine by 3 and a half washing machine. Or 0.1375 Sq ropes + a scroat
perhaps even a nano doubloon in cost
Im really liking this new measurement system, its making math really easy to understand
E=mc^2 to bucket loads of washing machines, why didn’t they say that at school it would have made loads more sense.
I mean I get the Empire State building is 59 London busses long
That’s like 5th avenue – I have seen 50 busses on one street in NYC, I totally get it.
Call me Cindy but i do on occasion visit the washing machine, I know it has one function that cleans my cloths - fast coloureds cleans everything fek knows what the other things do. Must be ME-2 functions.

The euro-nation made standard sized bananas law, they had to be straight as well.
you think we are crazy wanting to leave.
It came from one of Yunkers flippent remarks to take the p**s i think, but was he - im not sure he was ever sober to be honest.
@mklotz . BTW. I brought this up recently and my son informed me this is Babylonian method, not Newtonian. I looked ut up. This method is also known as Heron's method. His detailed deccription goes back to 60 AD.
The derivation of Newton's method is generally done by using the definition of a derivative. Since Newton (and Leibniz) developed calculus the method probably came to be known by Newton's name.
The Babylonians and Heron had nothing like calculus so it's not clear how they stumbled upon the iteration. My guess was by trying various numerical methods or by numerically extending something that works without iteration for perfect squares.
Example:
Let 'n' be the square root of 'N'. Then N/n = n and (n + N/n) = 2 * n so:
n = (n + N/n) / 2
It's not a huge intellectual leap to think that, if n is close to the square root, then the result of the above calculation should produce a number closer to the true root, iow an iterator...
n2 = (n1 + N/n1) / 2
Ancient civilizations may not have had higher mathematics; so stumbling across an accurate solution is very possible...
At the same time, some at least had tremendous grasp of concepts, functions and proofs to recognize calculations that work correctly.
Over time, lots of supposed calculations have been proven incorrect.
Later yes, but my favorite is still Eratosthenes; calculating diameter of earth within ~100 to 800 miles, practically from his own backyard! That to me is monumental beyond calculation alone, with science, observation, reasoning, mathematics working in concert. Likely, any deviation mostly due to the limited accuracy of instruments.
And one more thing; he wasn't first but KNEW earth was spherical.
I have solution to this argument over our measurement system which i have practiced with great success for many years. If i have to measure somthing and its closer to the inch scale than the metric then i use imperial otherwise i use metric, this theory also extends to CAD drawings and those on fag packets. A famous quote from Sir Isaac Newton " It is a better man who uses the inch than one who can only measure in mm" Or at least he would have said by now if he was still with us - god rest his soul.
holy crap, the worlds round - when were you going to tell me. Next you will say Pluto isnt a planet.
In the famous song title by Jellybean - im just visiting this planet
I missed the Apollo bus coming back from the moon so i had to wait for the next one, nobody said it ws the last bloody bus.
My ancient Greek math hero is Archimedes. He provided some of the first ingenious methods for calculating, as opposed to measuring, an accurate value of pi.
His geometric work was genius and he knew it was as the inscription on his tomb proves.
Archimedes' tomb had a carving of his favorite mathematical diagram, which was a sphere inside a cylinder of the same height and diameter. Archimedes had proved that the volume and surface area of the sphere would be two thirds that of the cylinder. In 75 BC, 137 years after his death, the Roman orator Cicero visited the tomb in Syracuse which had become overgrown with scrub. Cicero had the tomb cleaned and was able to see the carving and read some of the verses that had been added as an inscription.
Eratosthenes was indeed another genius deriving a way to measure his planet which he knew to be a sphere. Actually, most Greek intellectuals knew that; they reasoned that the phases of the moon were caused by the earth's shadow and the only form that could always cast a circularly curved shadow was a sphere. Good thing the Catholic church wasn't around then or they would all have been burned at the stake.
Exactly, Marv.
Facts, or at least sound reasoning withstand scrutiny far better than any kind of agenda...
The churches seem to have figured out that it's impossible to legislate reality. Their creeds no longer include specifications of how planetary systems are organized. Now all we need to do is get government to come to the same realization; I fear that is impossible.
The depressing thing for me is the fact that the majority of folks today cannot understand, much less duplicate, the mathematical ideas of men who lived 2500 years ago.
I am retired from teaching 35 years. In college one of the things we learned is that in order for society to thrive, the electorate MUST be WELL EDUCATED. One of the most scary things to me if that over that 35 years, and for the 10 I have been retired, it seems to be that the government is do everything that can to make the electorate LESS educated. All in the name of improving education.
In the name of kids learning more, they feel the need to test, test, test. When too many students do not reach the "standards" that were set, the test or the standards are modified rather than the instruction. In the district where I taught most of my career, and my daughter now teaches, they are told to "differentiate" instruction to meet the needs of individual students. At the same time, all teachers of the same subject, at the same level, in all buildings, must be giving the same lesson on the same day all year long. In addition to that, students who do not do well on tests, are able to take the test over and over, until they understand the material (OR at least do well on the test, even though they may not really understand the material!!!!!)
From my perspective, government is trying to make the electorate less and less capable of clear thinking and reasoning. As mentioned above, it is indeed depressing that, "...the majority of folks today cannot understand, much less duplicate, the mathematical ideas of men who lived 2500 years ago.", Or come up with good solutions to the new issues we face today.
Wait ,wait so let me get this straight if a kilogram is going to equal 1 pound does that mean the kilogram will be reduced by weight and volume or will the pound be increased Kilograms have always been tied to liters just ass grams to milliliters likewise the pound tied to ounces like ounces are tied to cups and quarts.
Maybe they should merge the yard and the meter or the mile or the kilometer.
Measurements are set by different standards and can never be changed to be something else so I say either chuck everything and start over from scratch or use one or the other of the existing systems chucking all of the other ways of measuring. Or as I have often heard the statement you do you and I'll do me. Od as I like it I'll do you if that is what you want and I'll do me when it suite me
does this mean that theives instead of half inching somthing have to half mm it. (cockney slang for pinch, steal, rob, librate)
liberate is a forces thing, if you liberate somthing it becomes free. If its free you cant steal it.
-It's just a joke, man!
For all you Kleptomaniacs here (who take things literally), some explanation of the joke could be found here:

Now I won't touch this thread with a 3.048 m pole (neither N & S ditto).
Think of an event in history around 1861 - US civil war perhaps - just as a time line refference
then consider that the standard weights and measures were lost in a fire in 1834 and wasnt until 1855 that the standards were recreated - who know if they were the same as the old ones of not hard to tell exactly as they were destroyed.
1866, the U.S. Congress passed a law that allowed, but did not require, the use of the metric system in trade and commerce

Around the same time France went metric

Followed by the UK in 1962

We have to accept that the EU has a huge influence this debate. (Mr DIYSwede will be thinking im having another dig, no my friend thats not the case at all. We like European countries just not the EU central government). So we may be switching to Imperial by Christmas just as the US goes Metric.
When it comes to drill bits I prefer two size numerations well possibly a 3rd
Imperial decimal for smaller or critical sizes higher end millimeter grades since those you can buy in tenths of a MM from the tiny through as large as you want, and lastly a fractional set in 64ths You can forget those 1,2,3s and A,B,C sizes I have no use for them although I do have a set of both
AFAIK: The European countries within the EU do not seem overly happy being treated the way your politicians have negotiated your Brexit.
Lately there seems to be "some concern" (in the UK and abroad) for yet another special law of yours efficiently violating International Law,
i. e. Boris' own suggested Brexit deal, accepted by both the UK and the EU.
Now: UK-proclaimed non-compliance to the Northern Ireland part of the deal (as I understood it).
Will there now be "The Troubles" 2.0 up there, apart from a darned hard Brexit?
-Well, good luck in your upcoming trade deal negotiations in 2021 with the other countries of the World,
who've seen the ongoing Brexit show and probably already drawn their own conclusions regarding UK's reliability as a trade partner.
OTOH: I can really understand your tiredness of EU central government:
Seems like you've got your own fair share of government inefficiency and incompetence to be tired of and handle yourselves,
so resist any further urge to export them all to Brussels & Strasbourg, please.

Note: I didn't even touch "the Duke of York subject".
This is my opinion and may not be totally accurate in everyone’s opinion - probably best this post comment ends here. no point giving a rebuttal as I’m just going to ignore it - its a subject which gets needlessly overheated.
Its always a pleasure my friend to be on the receiving end of your confusion with our mental state (that being the political one). I ask this simple question, why is it so hard for a country who wishes to leave to do so - i thought it was such a friendly union who respected each other.
The Irish situation, the Good Friday agreement was in 1998 the same year the border was dismantled, Ireland joined the EU in 1973. i wish people would see the wood for the trees. The Irish were still pagering long after they joined the EU. The EU was not the miracle which brought about peace.
https://www.irishtimes.com/news/irel...exit-1.3769423
The EU Irish border back stop is actually a brilliant thing by the sounds of it for Northern Ireland and North West UK. if the EU wants to keep a zero tariff zone in northern Ireland then surely Northern Ireland gets the best of both worlds - free trade with the UK and free trade with the EU. The North West of the UK is the supply route so basically the dock yard gate.
i can see why out so called leaders don’t want the back stop or at least want to be in charge of deciding when the backstop ends so it can be in charge of its own territory and not have other nations having control over it. The argument being fuelled by the republic actually has nothing to do with us. Their leadership is the EU take your argument up with them. Why because we are leaving must wen be faced with installing a border and controls - its the EU which doesn’t want trade bouncing backwards and forwards over their border not the UK. Emperor Hadrian didn’t get the Scots to build the wall to keep them out and Trump isn’t doing a much of a job to get Mexico to pay for his wall. It could be a fantastic thing if the EU representatives sat back and just thought for a moment, you know what that means we would get free trade access to the UK through the back door. So who is to blame for all the confusion?
Incidentally we are the third country that wanted to leave the UK, The republic of Ireland was the first, Greece was the second. Both were manipulated or dare i say it bullied into staying in. If you really wish to have a relationship with a friend in future you don’t go to the extremes of making sure you attempt to destroy them in the process. Our friends in the US should know very well how it feels to have your country ran by another nation, they might have kicked the crap out of the British and sent them home. And yet they are our closest allies and friends.
We wanted to leave as we were being used as a cash cow to support the EU whilst it took more and more control and attempted to expand its domain into further countries which would be looking for financial help and re-structuring. Our own nation was becoming deprived and thanks in no part to the fact that we are separated by water whilst the rest of Europe enjoys land connection. We were always at disadvantage. Germany and France always over powering any decision in their favour for the so called good of Europe . Throughout history many unions/dynasty’s have been formed and every single one has come to an end. Even in our lifetime e.g. the USSR.
What does the EU want, for us to say ok sorry we are staying – I don’t think we would get an easy ride getting a remain agreement now either. Rock and hard place springs to mind. The best thing that could have happened was for the EU to sort its crap out and said ok how we can manage this separation rather than blaming and hiding. What’s going to happen with the next country that wants to leave. Probably something entirely different – like a well managed and friendly separation.
So you think we are paranoid, its hard to be paranoid when you know people are actually talking about you behind your back.
I fought for my country and try to stay neutral but now im made to feel like a third class citizen, some of which i can directly blame on EU interference and pointless legislation. Their behaviour has only confirmed my decision.
Germany has been hell bent on domination of Europe for over a century they just found a way to do it without actually fighting this time. for several decades the USA has maintained a huge Military presents in Germany as a deterrent to attack from the old USSR. But once the wall had been toppled and the reunification of the East and West took place Germany again was or could have been an all powerful entity, but its economy was in shambles once the USA began downsizing the number of military bases there this caused another reduction of much needed money. the USA with its huge Military and civilian presents there brought in huge sums of cash. The formulation of something called the EU in my opinion only, was or is nothing more and nothing less than a way for Germany to dominate Europe. France has always been week in the knees allowing itself to be swayed in any direction the political winds happened to blow from other more domineering countries.
I don't know how Italy is now since it has been a long time since I've been there but it used to be quite strong at one time with a thriving economy of its own.
Poor little Spain and also Greece became whipping boys of the Eu from the very beginning as are most of the other smaller countries in the EU or they just go along to be going along hoping everything will be roses in the end. But little to they realize that Germany is becoming a dominatrix dressed in leather with whips chains and things to shove in their orifices.
I view Brexit as a good thing I only hope that Ireland Scotland Wales and others will be able to see it that way as well.
Its very interesting where this thread has gone. It seems the link to Metric system has dragged us into the EU debate, i wonder how that happened.
Im very mindful of not hijacking a thread - Jon will be itching to hit the big red button and delete our arses.
With regards the Duke id swap him for Anne Sacoolas, both are answerable.
I read yesterday that Jonny Rotten of the sex pistols had been banned from being on the BBC as he called Jimmy Savile a paedophile, ten years before any suspicion was raised regarding Savile
I think we need to be careful here. I have no use for lots of things that others find useful, but that is no reason to forget them or dismiss their usefulness for others.
It is the, "I have no use for ....." mentality that makes some people (especially legislators) think that "if I don't need it, no one needs it".
I would have hoped that this discussion would have help us be more open with our thoughts.
Hemmjo, agreed
I find it degusting how so much of our redundant machinery and tooling end up scrapped or shipped abroad.
This can only lead to a skills shortage and a further lack of services. Company owners on the whole are only interested in maximising profit and preventing any competition from new startups. In reality it is the opposite of what they envisage.
Take a small machine shop which sets up, gets bigger, changes machines for cnc, prices go up. Smaller customers drop by the way and if there is no smaller companies buying up their old equipment and picking up the slack then some products/repairs just don’t get done. If the big company reaches out a bit too far and needs a smaller shop to offer backup, its not there. The whole human/social aspect of work needs to be seriously addressed. Google and Microsoft already control our lives and our governments are insisting on everything going online and necessitating the need for IT in every home. To me PC = work, when im not working i want it the hell out of my life.
So back on point, i have a workshop full of useful items i purchased for projects which have now expired, their true value is a dollar on ebay. I have been listening to Jon Saunders and John Grimsmos business of machining pod cast https://www.nyccnc.com/business-machining-podcast/ In one post Jon Saunders discusses the hoarding of old pipe threading tools. He states his business does not require Pipe threading at this time and does not see any need for it in the future, however his grandfather handed the tools down to him so he is now stuck with a dilemma.
My workshop is a 1/3rd the size of a typical US garage or at least my Uncle Tony's was upstate NYC.
Do i really need the electronic Piano i never learnt to use, 2 old Allen Bradley plcs or the telescope. Not to mention the miss match of screwdrivers and spanners going back to childhood. There are 8 x mt3 dead centres and just other stuff. does JT Engineering have a need of such stuff in its future - no.
Do i have the time to put it on ebay, is ebay straight forward and stress free no. The toss up between skip and ebay is a very fine line, Lettered and numbered drills have no place in my life but when i started out i would have been immensely grateful for them. I never imagined i would own an imperial set of tap and dies and yet i do and use/need them fairly regularly. No machine or tools should ever go in a skip or for scrap and if you care about your countries future development consider handing down your old equipment. Developing countries need our help but to what extent do we risk our own development.
If the great Victorian inventors lived in Africa then we would now be the developing country looking to the rich nation of Africa. The creation and invention wasn’t free, it took time to develop and it takes an organised state to nurture that development. We get a huge amount of blame for the condition and way of life of developing countries but perhaps the need encouragement or just good old grit to succeed. Its easy looking at someone else’s success and wanting it yourself but putting your head against the grind stone and aiming for that ability/knowledge can only come from hard work and effort.
re MeJasonT and post 106.
That might be the best short essay on such affairs I can recall, and find myself in total agreement.
A little profane, but still very funny. Red Solo cups are American-manufactured, and a classic piece of Americana.

Some of these ridiculous sizings (they're not measurements) may arise because average adults and their children can't read a ruler or a tape measure. The dumbing down is well into the third generation.
Why is it that most to the "Metric" countries sell "pints" in the pubs?
"A pint glass is a form of drinkware made to hold either a British ("imperial") pint of 20 imperial fluid ounces (568 ml) or an American pint of 16 US fluid ounces (473 ml). Other definitions also exist, see below. These glasses are typically used to serve beer, and also often for cider."
True...

and exceeds the volume of three Olympic swimming pools.
And weighs more than 12 jumbo jets!
I'll never understand why the USA is still stuck in the old system. I was trained to be bi-lingual with SAE and SI in all my engineering and physics classes in the early 80s. But work did everything in Imperial, and put unit dimensions in parenthesis for metric.
And the worlds pilots are still using altitude in feet, barometric pressure in inches of Hg, and airspeed in knots. At least unit temperature operating ranges was in Celsius.
All the POTUS Jimmy Carter signs are gone from the roadways. And my latest auto does not have the dual speedometer range of earlier, only in MPH (and it's a Japanese design made in Mexico). If you live in states that incorporated as section road use of land, the mile will be stuck with us forever. As every mile, the state owns a 60 foot right of way, even across federal lands.
My only issue with the metric system is the size of the mm is wrong. Arbitrary. It should have been based on human factors of what the unaided eye can see, and be marked on a steel rule *. But like every other mistake, they become permanent errors that are supported forever.
.
.
* I'm not aware of any quantum length that could set an absolute standard. Human factor is why water is used for a temperature scale, metric weight used that as well. And it's only an issue when correct dimension analysis is not done.
At least my newer lathe has both scales, and a mix of Imperial and metric feed screws. It has change gears for metric and SAE thread, but I can't disengage the half nuts during metric, and that makes me razzle frazzle, and cuss.
Let's make a list of all worthwhile inventions that come from France.
