Here's another one, seed text in italics. Clearly some Star Trek used in the training data. "Engage", said Captain Picard from the bridge of the Enterprise. "But sir", Commander Data began , "this must have be

This is really a derivation of the Binet formula for Fibonacci numbers: that u_n = (phi^n - (-phi)^n) / sqrt(5), where phi is the golden ratio (1 + sqrt(5))/2.

Didn’t know that Allen had a big part in funding KEXP, in addition to all the well-known stuff (Seahawks etc). Crazy the impact one person can have on a city, even if that person is insanely wealthy.

I’m always hesitant to read a translated novel (especially literary fiction). Seems like too much would be lost in translation. Even putting language aside, without knowing the cultural context within China, would Lianke’s books be totall

I get robocalls that leave messages about once a day. These days it's some message in Mandarin. A few months ago it was something about health insurance plans (same message every day).

I don’t see why the “synchronized play” strategy described in your last paragraph also doesn’t violate the no signaling of any kind rule. If I have a Two but no One, then by consciously not playing on the first second of play I am signalin

I visited some dorm rooms in Croatia once, and they had a nice solution to this problem. Both doors opened inward, with the non-hinge side of the doors sitting very close to one of the walls with no doors. Instead of a conventional lock,

One area is scientific computing: based on, for example, the Top500 list, or their recent successes with the Gordon Bell prize (basically best paper prize for the biggest supercomputing conference). Of course there are a lot of political f

One source of bias here: there are lots of small schools, chances are high that one of them will exhibit a large number of founders due to noise, and this will be the one picked up by the report cited.

Once (also in JFK) I was quizzed a bit by the CBP officer. I told him I was a math grad student, he said "well, then tell me about the Euler problem". I explained that Euler was a fairly prolific guy, and asked if he could be mo

I thought so too, but they are after the references. Still I was disappointed that it wasn't a "proof without words" article.

Well one movie can be in many categories. And Netflix has some pretty diverse categories (e.g. "Movies featuring an epic Nicholas Cage breakdown", which appeared once for me). Though I suspect some of the 76000 categories contain

That's a fair question, and I have no hard data to back it up. Seems to me like it would be true (as another poster said, mostly number of edits, due to increased attention), but of course my intuition could be wrong. Still, since it

I'd think that after a celebrity does, there would be an increase in the number of edits / length of an article. Wouldn't this skew the numbers, increasing the "celebrity" statistic for everyone that has died that

The PCIE NVIDIA P100 has peak memory bandwidth of 730GB/s, at 250 Watts, which is almost exactly the same bw/watt as the MI8 (well, there are two PCIE P100s, I mean the better one).

I didn't really think about that case. In full generality, then the corresponding (n+m-k)x(n+m-k) matrix can be written as the matrix whose top-left (n-k)x(n-k) block is A\B, whose bottom-right (m-k)x(m-k) block is B\A, and where every

Not sure it's fair to say that graph theorists rarely use matrices to represent graphs: for many problems in graph theory some of the simplest solution involves representing the graph as a matrix (eg Hoffman-Singleton theorem).

Just a side note: The join of two graphs does correspond to a reasonably nice matrix operation: take the two adjacency matrices A and B (of dim m and n respectively, say), then form an (n+m)x(n+m) block matrix: A J J B where J is the al

Context is important here I think. This is part of a series of posts containing career advice for mathematicians at various stages ([1]), and not life advice in general. So I don't believe Tao was addressing cases like Torvalds etc.

To be fair, I think his main point was that the article was trashy for suggesting that millenials receiving help was unusual (and not to bash the parents of the 1 in 4).

Problem is that the camera is on top so if you rotate the phone and stand the phone on a surface, the camera is pointing in the wrong place.

Most of the articles I've read about this refer to a "tipping point": that we're crossing some line where the behavior of the system will change dramatically. But what are the actual consequences of this? Can anyone on
