comment Solving $\mathbb{E}_X[\log (a + X)] = b$ to $a$
Numerically, the solution is very close to $\log(2+a)$ (I'm interested in large $a$). Thanks a lot, this solved my problem!

comment Solving $\mathbb{E}_X[\log (a + X)] = b$ to $a$
@did, sounds interesting enough to proceed. Would you convert that to an answer with more details on the "yields"? It may not look that simple to others.

comment Solving $\mathbb{E}_X[\log (a + X)] = b$ to $a$
@Did, yes, I'm not sure it exists. I added the explicit formula of $P(X)$, in case it helps.

comment Is there a name for a matrix with all zeros on its diagonal?
I like this better; let's rename the wikipedia article from Hollow Matrix to zero-diagonal-matrix.

comment What exactly are fractals
@CharlesStaats, I see your point, but notice the question is "What exactly are fractals", which includes the sentence "I decided to get a deeper more mathematical knowledge of this, but sadly wikipedia hasn't been of much help". I myself am from Physics, and I know that there are situations for "intuitive ideas" and other for more formalism; I believe a proper answer to this particular question deserves the latter.

comment What exactly are fractals
@studiosus, ok, I was not aware of it. Can you provide a reference of that please?
