Is square roots the answer?

If it is, can someone explain why that's 'i' please?

"square roots" are not the answer by themeselves, not least because this would not fit with the phrasing of my original question.

However, square roots loom large as does Lydia's suggestion of imaginary numbers

In the world of real numbers, an expression like the square root of -9 is unsolvable. (Remember, because the square root of a negative number is not real.) However, by using the imaginary number i we can break this problem down as the square root of (9)(-1).
This can be expressed as the square root of 9 (which is 3) times the square root of -1 (which is i). Thus, the answer to this otherwise unsolvable problem is 3i.

There you go...clear as mud!!!

Eh?????????

which in a roundabout way tells you that, "i" is the square root of -1

so, over to Vicky (and we won't even go into 1 divided by zero!!!)

If zero is nothing, then surely you can't divide anything by it...?

Who came up with the imaginary number John? Your imaginary friend?

I think we should leave Harvey out of this

Sorry, I forgot it was my turn...I'm still thinking!

Who in their life had times of black, blue and rose?

Picasso?

Yes Lydia it is Picasso. I put times rather than periods because I thought it was less of a give away!

Over to you.

Oh bums. I'll have a think.

Right, done that.

What collection is shared amongst Moscow, St Petersburg and Berlin?

I'm guessing you went to the Berlin one then on your recent jaunt?

We did indeed.

Ostasiatische Kunstsammlung!

Lived in Germany for a couple of years as a child but we never got to Berlin as we were practically on the Dutch border.

Great place. Still haven't written a report - or uploaded any pictures. Lazy wotsit!

Which famous person's last words are said to be "Oh Dear!"

(I'm sure there may be others but the judges decision is final)

Erm, have I missed something? Did you answer my last question John?

or the east Asian collection most of which went off to Russia after the war.

I assumed that as you hadn't said this was wrong, that it must be right!

Oh, sorry. I didn't understand. No, it's wrong. I thought it was some kind of exclamation!! Idjut.

....and there's me thinking I was being clever - doh wrong again (on both counts)

Well you were - just not clever in the right way.............

totally stumped!
