Drinking with the old man

Anyone here enjoy a few beers with their dad?

No. Two reasons; one, he's been dead for several years, two, I'm close to teetotal.

But I do go out for a meal with my kids from time to time, when we find ourselves in the same city at the same time. This, unfortunately, is a rarer occurance than I'd like.
 
My family live out in New Zealand, so I make a point of having a beer with my pops whenever I get the chance, really nice way to catch up and become more of a friend than the whole father-son thing.
 
I don't go to the pub with my dad, as he doesn't really do pubs these days. I goto the rugby with him a lot, and normally have a drink there.

Alas I think I may get to see less of him and my mum with the impression my parents are considering retiring abroad soon.
 
I did'nt have a pint with my dad but I wish I could have done, I kept putting it off for some reason then he passed away suddenly and I feel terrible for the fact I did'nt go for a pint.
 
Yeah all the time, we usually argue about the best way to build things and he usually wins what with his fancy double charters and 35 years of experience. We also talk about how much of X would you need to do Y.*


*For example, how many atoms of iron and carbon would I need to make a steel girder weighing in at 5 ton?

:D

Well how many then? :p

I will figure it out for mild steel, hang on.

Assuming mild steel contains only Iron and Carbon and that there is 0.25% carbon then in 5000kg there is
4987.5kg of Iron
12.5kg of Carbon

Therefore there are
4967.5x10^3/55.85 moles of Iron = 88943.598925693822739480752014324
12.5xx10^3/12 moles of Carbon = 1041.6666666666666666666666666667


Therefore using a constant which I have forgotten the name of there are
53563093824977618621307072516 atoms of Iron
627306406250000000000000000 atoms of Carbon

In a 5 ton steel girder.

I think MS calculator meshed itself there though...

5.32 x 10^28 atoms of iron

*EDIT* At a guess :p

I dont know how to read what you just did :o

Can you please either explain how to read it or type in the actual number? :)
 
10^x

Basically the number where x is means how many times the number is multiplied

10^6 would be

1,000,000

But you can shorten things like

1250000000000 by

1.25 X 10^12
 
So the number after ^ is how many digets are on the end of it? :confused:

As you can see i didnt do very well in maths :o
 
Yeah if you are doing it like that.

I didn't do very good at maths either because what I have figured out is wrong. :D

Haircut has it about right I think.
 
It's on post 28 in this thread ; I got similar for iron, but my carbon is out by around a factor of 40, your proportions are correct and I can't be bothered to do it again. :p

Oh yeah, didn't see your edit.

I used 1% carbon in my calculations so maybe that's where we differ?

BTW It's Avogadro's constant you were thinking of.

I think mine are wrong because MS Calc is just complicated to use and I can't be bothered to find a proper one.


Not to mention that I am tired, I have done my A-Levels and never want to see chemistry again.
 
My dad doesn't believe in drinking. Even when I was 21 at family parties I would drink vodka and a mixer (poured at the bar, no slice of lemon) because he wouldn't like to see me drinking something that looked like alcohol!
