 Feb 18 comment Can a Dirac delta function be a probability density function of a random variable? Gortaur's answer does not exist. Could you update the answer with the relevant content in the original answer? Feb 8 asked Ergodicity of the natural measure implies uniqueness of the invariant density? Jan 22 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! Jan 22 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. Jan 22 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.

I like this better; let's rename the wikipedia article from Hollow Matrix to zero-diagonal-matrix.

Please improve: which "first" paper? where are the golden coins? Sep 2 awarded Tumbleweed Jun 6 answered Prove sensitivity to initial conditions numerically?

"If you can't solve a problem, then there is an easier problem you can solve: find it." - George Pólya Mar 11 awarded Citizen Patrol Mar 9 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.
