for me 2/3 66% is a fair approximation 3.142 is a good approximation to PI So to get this from HL re a recent open offer on shares The open offer was oversubscribed, all basic elections were satisfied in full and excess elections were satisfied to the extent that shareholders received approximately 70.97747% of the excess shares applied for.that right the last digit is 100,000th of a percent , I'd hate it if they were being precise  |

Ah, but 100,000th of a percent could completely spoil the present. 🎁 Imagine God tying a ribbon right around the Earth, as a gift to another god. If the ribbon were 100,000th percent too long, for a 25,000 mile circumference, that would equate to around 4 metres of excess ribbon.  This excess would look very untidy and God wants to keep the bow in a proper circle, with no rucks. So how high off the ground would s/he have to lift the ribbon to take up this 4 metres excess slack? The answer might surprise you. Instinctively, you might imagine raising it a centimetre right around the globe would be way too much, meaning the ribbon would be left far too short. In fact, the ribbon would have to be raised a whole 2 feet off the ground right around the entire circumference, to make the two ends meet. No mean feat, and all because of that 100,000th percent inaccuracy! [ 2pi (R-r) = 4 metres, leading to (R-r) of 64cm or very roughly 2 feet ]. Sorry for my crazy little diversion, but the ribbon (or rope) around the world paradox has always fascinated me since school days! 😁 |

I genuinely didn't know it had been on QI, but it doesn't surprise me because it's a lovely paradox.

It's not a paradox, that the circumfrence of a circle is '2 pi r' is taught to every child at school and is one way to define a cricle (or really pi, depending on how you look at it) The reason some people struggle "intuitively" is they don't think, and assume the question concerns a volume because its about a sperical planet (goes like r^3), but the relevant units are actually only length (goes like r).

But yes, agreed. Just waiting for somebody to point out that the Earth is not truly spherical next...

How many were in the issue?

Round objects.
Using any opportunity to give an outing to the brilliant Yes Minister scripts...
Episode One: Equal Opportunities
[How to deal with a nonsensical complaint]
Bernard: We can CGSM it.
Hacker: CGSM?
Bernard: Civil Service code, Minister. It stands for "Consignment of Geriatric Shoe Manufacturers".
Hacker: What?
Bernard: A load of old cobblers, Minister.
Hacker: I'm not a civil servant. I shall use my own code. I shall write: "Round Objects".
[...later...]
Bernard: You remember that letter you wrote "Round Objects" on?
Hacker: Oh yes.
Bernard: It's come back from Sir Humphrey's office. He's commented on it.
Hacker: What does he say?
Bernard: Who is Round and to what does he object?

Just watching an episode of Only Fools and Horses featuring Daniel Peacock (aka mental Mickey). 35 years after his sole apearance in the sitcom, people still approach him asking that he says the imortal words 'I won't tell you again Rodney, I do the one, two, three, fours'

During my time in the construction industry it was commonplace to mix systems. Method statements often referred to a 300mm diameter drainage pipe with 6" of concrete surround.

I did consider this at the outset, but decided 2 feet was a nice agreeable figure and far easier to visualise for most people than the fairly meaningless 60-something centimetres. I suspect you still talk about miles per gallon, though, despite buying your fuel by the litre. It's much easier to visualise than litres per 100km. Just remember the mental calisthenics involved in leaping around between these different dimensions are positively good for the old grey matter..... and I charge nothing for this service.

Entirely depends on what you're used to... I suspect the vast majority of people of middle age and below in this country would find 60cm at least as easy to visualise as 2ft. Globally, no contest. If we'd have actually done the job of metrication properly 50-60 years ago, this would have been a non conversation ever since. It's astonishing that it's nearly 40yrs since this country stopped selling fuel by the gallon, yet we still measure consumption by it... Particularly so, when you consider the only other country in the world to use a gallon uses a different size... As for mpg vs l/100km, they're measuring completely differently... mpg - distance per unit fuel. Bigger, better. l/100km - fuel used per unit distance. Smaller, better.
