Kedves Arpad. Gyakran a kerdes a fontos, nem a valasz. Ebben az esetben is a szoveg kornyezettol fugg. Az en meghatarozasom szerint ket-harmad egy jo arany ha eselyekrol beszelunk, de rossz arany ha egy felmeres pontossagat vizsgaljuk. Laza kerdesre laza valszt kapunk. Mi a feher? Egyszeruen egy szin, esez a valasz is lehet pontos. De mivel szinek nem leteznek csak elnyelt vagy visszavert rezges hullamok. Esetleg, mas kornyezetben, a tisztasag jelkepe. Well it depends on the context. It can be a good ratio when one considers the possibilities or a bad ratio when one is considering the results of an investigation/survey. One needs to define the question well to get a correct answer. An analogy would the question of what is "white. One could say simply that it is a colour and it would be correct. But since colours are just absorbed or reflected vibrations, this might as well be a good answer. I a different context, it is the symbol of purity. One needs to be concise and precise. Otherwise an excellent question to prompt young ones to start thinking abut their definitions of things and phrases commonly used and misused.

Dear Jozef,

I have read your answer, both in Hungarian and

English, with pleasure.

However, from it I coudl at once see that

you are not a mathematician.

You appears to be rather a philosopher, than

a physicists.

With best wishes,

Arpad

Dear Jens,

Indeed, the context is really an important thing

regarding questions and answers.

My questions are only for those who have

learned at least a little, rigorous algebra or analysis.

With best wishes,

Arpad
