Funny, a half a year ago I was thinking whether or not I will reach 2,000 posts by the end of the year and my conclusion was No, but close to it. Apparently, I have never been more wrong (I guess I divided by zero somewhere).

Anybody interested what my first two questions were?
My first question I think is really interesting:
Does there exists non-trivial solutions to,
f(x+y)=f(x)+f(y), \forall x,y\in \mathbb{R}.
In this case trivial are linear functions, f(x)=ax.
My first post appears to have been (at least it is the oldest I can find):

If you take a number out of R and take its power, it will be a number in R again and not Q.
How about (-1/2)^(-1/2)?
