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 Finding out a person's age in days given their birthday dd/mm/yyyy?
For people who are born after 1970: Convert the number current date (today) to a unix timestamp (number of seconds since 1970) and subtract the unix timestamp of their birthday.

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?)

comment How is it called when you apply min / max seperatly to each dimension?
That's a nice formal way to describe it (+1), but isn't there a name for that?

comment How do you call it when you remove the top n% and the bottom n% of a dataset?
Simply a histogram. You can see a neat visualization of my data here: tex.stackexchange.com/a/195034/5645

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 :-)

comment How do you call it when you remove the top n% and the bottom n% of a dataset?
Some of those values are extremely much higher than 99% of the "normal" data (the maximum is about 10,000 times higher than the maximum of the remaining 99%). So I really want to remove the top 0.5% of the data. The minimum is not that extreme (as the values are not so high and non-negative). The only reason why I remove the bottom 0.5% is due to symmetry.

comment How do you call it when you remove the top n% and the bottom n% of a dataset?
@AndréNicolas That sounds as if you want to say that I would manipulate data that does not fit to a hypothesis. This is definitely not the case. I will mention those outliers in the text and write down at least the maximum. The only reason why I want to remove them before plotting is that the plot would otherwise be very hard to read.

@AndréNicolas: Why embarrassments?
