Godel's incompleteness theorem say that a system of sufficient complexity can not be bother complete and consistent [0]. Consistency ensures that statements can not be both true and false (under a given set of axioms). Completeness say

In my opinion, a big part of the success of Wikipedia is that it offers its content under a libre/free license (CC-BY-SA). This specifically allows for commercial re-use and re-sale. The license provides a wide umbrella so that many di

So, I'm not sure but I think what's going on is that a scammer calls and asks the "victim" (in this case, Kitboga) to transfer funds into one of their Bitcoin wallet addresses. This can be done via a Bitcoin ATM which wi

The human brain is estimated at 2.5 Pb of storage [0]. Currently 1 Tb costs around $12.50 [1]. If this costs reduces by half roughly every two years, 2.5 Pb of storage will be available for roughly $4k. At $4k and below, that means we essen

If you don't make any assumptions about the underlying distribution you're associating with the risk, it can be anything, so I'm not surprised you haven't found an explanation. For example, the risk could be dependent on

The Kelly Criterion [0] tells what strategy to employ if you're given fair odds on an unfair coin. For example, if a bet can be made where you get 1:1 payout for a coin that's weighted heads with probability 0.8 and tails with pro

A universal Turing machine can be made with two symbols, so in the sense that there's a reduction from one to the other, yes. I would say a better question is to determine if there's some type of polynomial time/space reducti

Intuitively, it measures the difference between two probability distributions. It's not symmetric, so it's not quite that, but in my opinion, it's good intuition. As motivation, say you're an internet provider, providing

I like to think about this in terms of "ensembles", or a distribution on the problem instances you're drawing from. NP-Hard talks about worst case in this set or distribution, even if the "average" or "normal&q

OK, that's fair, I was being too critical of Gleick's book. Even so, this doesn't really get at the high level symmetry. Gleick's book might give some motivation for the chaotic points being restricted to a compact domai

Yes, the high level rotational symmetry. There's some gross level structure that's preserved while the individual points are (presumably) completely aperiodic/chaotic. What's some insight into the gross level symmetric f

I've skimmed Gleick's book before and my feeling is that it's a high level overview of the subject without much content in either explaining the underlying math, the motivation behind it or giving some deeper insight into the

That was fun. Very reminiscent of sys admin bug hunting/maintenance. I do wish they cleaned up the input. Not nice opening one of the files and seeing a racial slur.
