You got it!!!

[AimusSage]

yes, I'm still don't get the riddle by taliesin though.

[Taliesin]

Is it that, the echo has this range, and after it has touched all the values, it comes back to its first value.

I know its a foolish answer, but a guess.

It is an interesting answer you and Pen made together, but it isn't the one we were told.
The time of the echo really shortened.
And, as we have told before, if we had done the experiment, the line in the graph would have continued falling.

[Pendragon]

Please tell us or shoot us, Tal. We seem to be missing our shot, and in a duel, I believe that makes it your turn. "Ah, young Taliesin! I bare my chest and await your pleasure. You may fire when ready!"

[Madhuri]

Is it the distance where the scientist was standing? Does it have to do something with the sound quality?

Plz, tell us Tal.

Madhuri, I’m sorry, but I just can’t comprehend
Why four equal cuts do not bring puzzle to an end.

[Madhuri]

Madhuri, I’m sorry, but I just can’t comprehend
Why four equal cuts do not bring puzzle to an end.

Well, it is like this:

Vertically - cut the cake like a cross, which will make it into 4 equal parts
Horizontally - Cut the cake into half, using only one cut

this will result in 4 parts above the horizontal cut and 4 below, hence the 8 equal pieces.

This is what Aimus replied. It was correct.

I do not think, three full diameter cuts will be equally spaced.

[RobinHood3000]

Three will not, I believe I "misspake,"
But four, will they not make eight pieces of cake?

[Madhuri]

What is the manner in which you are cutting, if four?

Is there any other way to get 8 equal pieces, I would like to know.

Edit: I think, four horizontal cuts and one vertical cut will also result in 8 equal pieces. What do you think?

[RobinHood3000]

Four cuts equal round, like the spokes of a wheel,
Perhaps the puzzle was to use but three cuts, I feel.

[AimusSage]

Yes, that is it robin, I was familiar with the question. 4 cuts would do just the same, and is probably more fair too, since everyone would get a similar piece of cake. instead of a top or bottom half.

[Taliesin]

Please tell us or shoot us, Tal. We seem to be missing our shot, and in a duel, I believe that makes it your turn. "Ah, young Taliesin! I bare my chest and await your pleasure. You may fire when ready!"

Hmmm...as you wish. We ourselves were also beaten in that duel before, and seem to be alive, so no worries.
Although, rain these days keep spoiling the gunpowder, but...anyway...

The answer is: the hair.
The scientist didn't understand why it was so until one of his students asked him: "How often do you visit the hairdresser?"
It turned out that the scientist visited the hairdresser exactly every 14 days. So - the hair slowly became longer which shortened the time of the echo - and when he had his hair cut short, then the time of course lengthened rapidly.
We visited the hairdresser about a year so when we had done the test, the graph would have continued to fall.

And that's all, folks.

[Madhuri]

Now this seems to be a new puzzle to me.

I did not understand the relation between the length of hair and the echo time.

[cuppajoe_9]

Oh, I see. The longer his hair was, the more it muffled the sound coming to his ears, the shorter the echo seemed to be.

[Madhuri]

So, that's what it is, we have been thinking of what not, sound waves, sound properties, and anything and everything, and it comes down to this.

All complex problems have simple answers, I guess.
