DISAPPOINTED!!!!!! (Which film is that a quote from, KKKKen?) Nobody has solved the chessboard puzzle. OK maybe nobody reads my blog but I know at least 3 people who did and there may be more out there. So here's a clue: 2 to the power 10 is approximately the same as 10 to the power 3. Now come on.
The best event recently was the famous Golden Weeding Weekend of my fab parents - ALL their children and grandchildren were there, together with husbands, wives (and wife to be ! - congrats John and Katie!). On Saturday night we went out to a Very Nice restaurant, French speaking waiters, private dining room and a wonderful ambience. On Sunday we had a major family party all day at Bob and Isa's involving endless talking, assiduous eating of splendid cuisine, and the ultimate musical afternoon! There really is nothing like family. It's God's way of showing us what community is all about, and a glimpse of heaven.

I'll get in there first - it was a Golden Wedding not a celebration of gardening!
Aww nice pics The Dar!
:) It was a fab weekend. Can't wait for THIS weekend!!
And yes, weeding weekend...hehehe
Alright then...
2^64-1 sounds good.
So if 2^10 is about 10^3
then 2^60 is about 10^18
and 2^64 is about 1.6 x 10^19
Is that right?
Thanks for sending the Maths challenge paper, we're sweating our way through it. I can't believe that they only allowed 1 hour for 25 questions - 6 hours would be more realistic!
And thanks for posting the Golden Weeding pics - lovely to see them!

Browsing around I found on Wikipedia that the actual answer is 18 446744 073709 551615

Well, I thought this number looked familiar. Yes, it's also the answer to the Towers of Benares puzzle!

Nice explanation Peter! Powers of powers = multiply the exponent (that's what logs are based on - we are from a generation that used Log tables). Checking it with Excel rounds up the last 6 figures but with a bit of fiddling about I validated the last 6 digits of the exact answer you quoted!
*ahem* GEEKS
