Road Signs: Time to change to Metric?

Do you think I'll get a Nobel prize for working out how to double the density of matter, after all if I keep adding strawberries I can make matter almost infinitely dense and so make my own nuclear fusion reactor in the shed?

Science eh! :-)

Interesting, Alan, but we are not talking about altering the density of strawberries, but the difference between the density of product and air. Simply remove air, and you can get more product into the same volume, so it will weigh more. And you do this by using smaller pieces. It’s the difference between theory and practice, so no, I don’t think I was pulling your leg.

But it’s well over 50 years since I did physics A level........

Hi again Malcolm,

Perhaps it is me that is pulling your leg then - it is 38 years since I completed my physics degree :-)

Good fortune,

Alan

Looking at your avatar, I suppose you also topped me in the Services.....

I was only a Corporal Air Trafficker.......

😁😁😁

Hi again,

That was all in the past - there is no topping anyone here.

I was an Army colonel (retired now). There is nothing at all wrong with being a corporal in the Royal Air Force, I'm sure you are (rightly) very proud of that.

Good fortune,

Alan

Morning, Alan; morning Malcolm. I have the dubious honour of having failed my Physics 'O' level in 1965, but - all leg-pulling apart - I think you could both be right. Malcolm's point about air 'pockets' is the logic behind flat pack goods - Ingvar Kamprad knew that well!

Regards, John.

Of course John. Malcolm and I were just enjoying some light hearted banter - we both understand each other's points perfectly well.

You guys get up early for your banter
But oddly this popped up on youtube last night, with a guy shredding aluminium cans to get more in the pot (quite why he felt the need to shred them 10 times escapes me).

I've gone right off strawberries now Alan has said they're nuclear.

But on the question of density why when I was working delivering into the building trade did people believe wet sand was less dense than dry sand? to me logically the water fills the interstices of the dry sand so adding weight and density.

And that brings to mind the story of the University lecturer who at the start of the term takes a large jar and gets a student to pour in some sand, the next student pours in some gravel, the last student is given some cobbles to put in but the jar is already half full of sand and gravel to full to fit all of the cobbles in; the lecturer then gets another jar, pits in the cobbles, then the gravel which slips between the cobbles, then the sand which flows between the gravel, and it all fits. He then tells the students that this is about priorities, the cobbles represent the big things in life so fit them in first, then fit the next most important things around them, then fill your time with the other stuff. The students take in the message, but the lecturer then pours in a can of beer and declares 'But no matter what, there's always room for a beer!'.

Excellent David, good story.
Alan
PS. I'm not really making a nuclear fusion reactor out of strawberries in my shed.

[Baxlin]

Actually, Dave, I had put reference to a similar version of that story in one of my replies to Alan, but deleted it and decided to go with strawberries instead. Like me, they are sweeter.....

Going totally metric......

How about going the whole hog and perhaps change to driving on the right?
Just like Sweden did in 1997.
