The murderer winks at me and I suddenly fall down a pit, break my leg, get bitten by the rare vindscreen viper, spontaneously ignite, get put out, catch fire again, get pecked by numerous chickens and finally get crushed by a falling shipment of encyclopedias. Oh, buckets.

I have just had a puzzle sent to me ... it seems very easy.

... a simple note that says "Prove that 1=1"

Wellll... doesn't 1=1? but how do we PROVE it?

You have shaken the foundations of Mathematics.

If someone asxked me to do it,

I'd simply say take cube roots on both sides.

If the cube roots are equal, the numbers are equal

But if you take the cube roots of both sides, we still have 1=1. It gets us nowhere! The number 1 resists the cube root method! It is evil numberified! WAH!

Robert Recorde, who gave the world the '=' symbol, would be fuming!

What more do I do?

Multiply both sides by n (n ≠ 0,1), we get n=n !

n IS EQUAL TO n. How do I prove that?

Taking Log on both sides wouldn't help, because we would than get 0=0, which gives us absurd results.

When both the sides are raised to the power n, we still get 1=1 !

When both sides are divided by n, we bget 1/n = 1/n which is the same as n=n !

How about some practical methods? Draw a straight line of 1 m. Draw another of 1 m. Both of them would be exactly equal. Or, 1 hour is the same everywhere on the planet!

I give up

I think Rora because the murderer is going through the alphabet, starting at the middle.

(Just to clarify, that's who I think will die next, not who I think the murderer is.)

Hmmmmmmmmmmmm. Now that you said that (unless Rora has already been e-mailed) the killer will either choose someone else, thus disproving your theory. However, the killer might kill Rora, grusomely, horribly, and loads of other words that are hard to spell when it's hot, thus proving your theory.

Or the killer might not even read this post and kill you, again. (I know you've already died, but oh well)

A stranger offered me a bottle of coke. Coke has always been my favorite. How could I resist? Without any suspicion, I drank the entire 300 ml. Later, I started feeling dizzy and I realized I was poisoned. But it was too late. My legs were too weak to carry me and I fell dead.

This is starting to become a repeat of the first game, and we all know how badly that one went. GUESS, SOMEBODY!

When you say "it#s him" you should say "it's her".

* HEY!!!! *

If someone guesses you, you have to say whether you are or not. With no cryptic clues or suggestions.

Anyway, if it was you and you told me, you couldn't kill me as the game would be over. *If* you weren't the murderer and you killed me, this game would become very complicated, as it would have several murderers.

Ok. This is confusing. JUST TELL US!!!!

I would tell you, but dead people can normally only say one sentence at a time, and even that takes... great... eff...urk.

You're too good insomnia, just too good. So, what next?

Oh, btw... I just reset the awards. I think I got everybody.

I think we should wait a while to give new people a chance to join up or playing people a chance to leave. At the moment the list is (I think) MathsIsFun, justlookingforthemoment, Zach, me, insomnia and ganesh. As we don't know yet if Rora's gone permanently or not, I've taken her off for now.

I'm not gone permanently, NO WAY would I do that! But I think the best thing to do would be to take me off unless I ask to play again. I may find some un-busy days occasionly.
