[DaleCooper]

2,000,000 ?

More than that.

1,000,000

More than that.

Ten to the power of 20?

Not that many fortunately.

More than that and that's not an average human being.

I will guess at 1 picogram = 1 x 10^12 grams so 1 x 10^-12 / 239 (I will go for a fairly common isotope atomic weight) moles so


1 x 10^-12 / 239 x Avogadro 6.023 x 10^23 - simplifies to 10^+11 x 6.023/239 - I will round so 6/240 = 1/40 so 1/4 x 10^+11 = 2.5 x 10^10 = 25 x 10^9 - so approx 25 billion ?

 

[GRALISTAIR]

I think I made an ERROR

 

[GRALISTAIR]

10^+11 x 6.023/239 - I will round so 6/240 = 1/40 x 10^11 so 1/4 x 10^10 = 0.25 x 10^10 = 2.5 x 10^9 - so approx 2.5 billion ?

10^+11 x 6.023/239 - I will round so 6/240 = 1/40 x 10^11 so 1/4 x 10^10 = 0.25 x 10^10 = 2.5 x 10^9 - so approx 2.5 billion ?

Still a bit low but full marks for your maths.

You should have stuck with this answer because...

100 billion

That's within one order of magnitude, the answer I have is 180 billion. Your turn...

It has been calculated that the human body has always carried a base load of, perhaps 103–105 atoms (< 0.2 amol) of natural plutonium. Since 1945, the release of 239Pu into the environment from atmospheric nuclear weapons testing has added to this base load a civilization-related load which, at ≈ 300 fmol, is at least 5 order of magnitude greater.

(300 fmol = 1.8 x 10^11 atoms approx.)

 

[Strat-tastic]

Zero atoms; loads of ions

What is the name of the King of Norway?

 

[D6130]

Haakon?

 

[xotGD]

Haakon?

Nope

 

[D6130]

Olaf?

 

[Peterthegreat]

Harald.

 

[xotGD]

Olaf?

He was the previous king.

 

[xotGD]

Harald.

Correct!

You may wear the crown...

(Haakon is next in line.)

 

[Peterthegreat]

Thank you.
Josef Naus is credited to be the first person to climb which mountain?

 

[Gloster]

Matterhorn?

 

[SuspectUsual]

The one at Garmisch. Tallest mountain in Germany. Can’t remember the name. Begins with a Z I think

 

[Peterthegreat]

Matterhorn?

Not the Matterhorn.

 

[Peterthegreat]

The one at Garmisch. Tallest mountain in Germany. Can’t remember the name. Begins with a Z I think

It is at Garmisch.
It is the tallest mountain in Germany.
It does begin with Z because it is the Zugspitze.
I think you've done enough so over to you to climb the next mountain and ask the next question.

 

[SuspectUsual]

Staying in Germany, what's unusual about most of the streets in the centre of Mannheim?

All in a grid pattern?

 

[SuspectUsual]

All in a grid pattern?

They are, but that in itself isn't particularly unusual. What else?

 

[DaleCooper]

Staying in Germany, what's unusual about most of the streets in the centre of Mannheim?

Cobbled

 

[SuspectUsual]

Cobbled

Quite possibly, but again not unusual in itself. Something else

 

[Peterthegreat]

Was the game of "Battleships" invented there?

 

[SuspectUsual]

Was the game of "Battleships" invented there?

It might have been, and I suspect you're toying with us now. Care to elucidate?

 

[Gloster]

Are they numbered or lettered, rather than named?
