Fascinating Facts

I'll start seeing as it's my idea.

If you subtract your age from the current year you get your birth year.

[Draytonian III]

What if you’ve not had your birthday yet this year

[Bentley Bullet]

What if you’ve not had your birthday yet this year

You mean like me! Mine's tomorrow, so it doesn't quite work for me, but it is meant as a much-needed light-hearted thread!

On a clock face if you add the 12 and 1 which are next to each other you get 13.
Then add the corresponding numbers on either side 11 and 2 you get 13.
Followed by 10 and 3
9 and 4
8 and 5
finally 7 and 6.

All 13.

And Whitgift Church on River Ouse bank east of Goole spoils that because ....

It has XIII at the top of its dial .

I.think.thats a fascinating fact

There's  story about the great German mathematician Carl Friedrich Gauss when he was 6 years old at school.

Apparently, to keep the kids occupied, his teacher set them the task of adding up all the numbers from 1 to 100.

Before the teacher had sat down, Gauss puts his hand up and said 5,050 sir.

How did he do it so quickly?

[tommy toes]

I’ve heard of this BST its adding the first and last remaining numbers, similar to the clock above.
The answer is always 101.
But cant recall how he got to 5050.

[tommy toes]

Oh it’s obvious I think, when there is only the 50 left its 50-50 but how he realised that that must be the sum of the numbers is beyond me.

[BillyStubbsTears]

Nearly Tommy.

There's 50 pairs.

1&100
2&99
.
.
.
49&52
50&51.

So there's 50 lots of 101.

50 lots of 100 would be 5000. Then add the last 50 on.

[Colemans Left Hook]

1 ----100
2----99
3--98
4-97



Sigma  Σ 50 of  em at 101 a time  and wot is 50 times 101 ??

now my turn  

Comrade Starmer pays his lackey £100 a week and for Christmas in Scrooge style reduces his wage for a week by 10% so he pays him only £90 for that week

then he says to the Lackey he will put his wages back up by 10%  and pays him only £99 .   

How did Starmer manage to fleece the lackey of £1 ???

update

I was watching Celebrity University Challenge as i was typing this and it took me over half an hour to multi-task ??

we pause the prog to come up with our answers so it takes an hour to watch

Fun fact - if you mistyped 2592 with 2⁵9² it wouldn't make any difference

[SydneyRover]

Is there some trick to this that I've missed DU?

[Dutch Uncle]

2 to the power 5 = 32
9 squared = 81

32 * 81 =2592

So 2⁵9² = 2592

It is what is known as a 'mathematical accident'

edit: As a mathematician I find that a 'fascinating fact'

By the way the Gauss story and the explanation of pairing numbers as above leads to the formula for the sum of the numbers 1 to n being equal to 0.5*n*(n+1), and which is true for both even and odd numbers

So n=100 means sum of 1 to 100 = 0.5*100*101 = 50 * 101 = 5050

I reckon it must be highly unlikely the 6yr old Gauss knew this formula, so I suppose he must have thought of the pairing approach himself, which is remarkable.

no respect to Dutch Uncle (who's intelligence I highly respect)

but if I had typed that Old Tommy Toes ( one of BST's Batmen)  would have typed

"Ignoring the shite above."

Right

In the fifties when no substitutes were allowed  ...After a local amateur football match there were only 7 pies for 22 players

How much did each person get ?

Answer one over pie

DU
As I'm sure you know, the very closely related 0.5*n*(n-1) is
the number of handshakes that take place if everyone in a group of "n" people shakes hands once with everyone else.

[BillyStubbsTears]

And one that I'd instinctively thought was related but isn't.

You only need 23 people in a group for the odds to be shorter than evens that two of them share a birthday.

Is that what they mean by the cake number?

Your fact about 10% of £90 was shite too.

Thanks DU didn't read/see 32x81

Your eyelashes are attached to (or are in fact) the same hair that grows from your bum.

Try pulling a hair from your rear end & THAT’S why your eyes water.

Yes , I had the calculation given to me for 30 people in a Room and what are the odds of 2 of them having the same birthday

I think it was very very very slightly more than evens

Can't find it anywhere though

[Dutch Uncle]

Fascinating fact - since modern Olympics events began in 1896, 'going with the leap year', the summer event has actually twice been held in a non-leap year.

Will await guesses as which before giving the answer 

[Dutch Uncle]

Since we have now moved away from a leap year since I posed this question, the answers are:

The planned 2020 Tokyo Olympics were held in 2021 because of COVID, and the 1900 Paris Olympics were held in 1900 which was not a leap year (rule at Centuries is that first 2 digits must be divisible by 4, so 1900 was not a leap year while 2000 was)

I have been asked to be quizmaster at a fund raising quiz in March, which I stupidly agreed, and am now very nervous. I was trying out this question. I initially forgot to exempt Winter Olympics from the question.
