comment How should graphs of True Positive Rate / False Positive Rate be interpreted?
I am quite sure that the tag is wrong. However, I don't know what good tags would be. Please correct it if you know it. Also, English is not my mother tongue. Feel free to correct any sentence that seems to be a language mistake.

comment Prove that the 25 people can be seated in this way
if A and B are two different people with the same specialty (for example, two mathematicians), then the people sitting to the immediate left of A and to the immediate left of B are of different specialties: Isn't that the same as saying: When A sits next to B and C, then specialty(A) $\neq$ specialty(B) AND specialty(A) $\neq$ specialty(C). Or less formally: Nobody sits next to somebody with the same speciality.

comment How far can one see over the ocean?
A while ago I've calculated how far you can see from Burdsch Chalifa: Sichtweite des Burdsch Chalifa. It is in German, but eventually it is still of use for you (with google translate?)

That's a nice formal way to describe it (+1), but isn't there a name for that?

I've just talked with a friend about it. He suggested using another plot type. It turns out that this works much better and I can even include the outliers :-)
