I did. Though in another form. Yet, with a 100$ prize offer and a bonus for extra $100. No one collected the prize. Only one reply was mailed, without much help.

If you "can't say anything about it" what does that mean? What are the kind of mathematicians I should look after? Can you suggests names?

How do I pick the right people from within a thread, without getting entangled with non-proper people? I run into the Beal's conjuncture. Also to Catalan's. Thanks.

I thought this is what you had in mind. When you use a saying, it is very hard to shorten it, without loosing its taste. Just like in poetry. Remember, it was filtered by the best filter. Time itself. In this case, about 2000 years.

The original saying is: "vedai lechachima birmiza" Assuming you know Hebrew, your quote, change the meaning of the saying. I am not sure even if it's grammar is correct.

Ah, you got the saying wrong.

It doesn't say anything on any background. The saying just say that for a wise guy, a hint is enough. Obviously, the saying is not addressed to the wise. It is just another saying _on_ wise guys which should be classified as "how would some one know who is the wise" Among that list would be: "The one that can forcast the born", etc'.

It was underestimate.
A real beauty.
Keep going.
