Wait

Hurewicz is pronounced hur-RAY-vich??

/hɚˈɹeɪvɪt͡ʃ/

@AkivaWeinberger why not?

it's a Polish name

I don't know what I expected but I was surprised anyway

cz is /t͡ʃ/

like czech

I guess I thought it would be HUR-vich

or something

or HUR-e-vich

The more you know

well Polish doesn't have silent letters

it's HUR-e-vich according to google translate though

where did you get your first pronunciation

A video lecture by John Milnor

at around 47:25

Also apparently John Milnor is also called Jack

Hm, maybe the stress is different in English (wouldn't be the first time)

@ÍgjøgnumMeg Sounds like that's putting it on the last syllable

I hear it definitely on the penultimate syllable

@LeakyNun Did you know that in the Uyghur language, the 'gh' is like a French r and the 'r' is like the Spanish 'rr'

(and also accent on the last syllable)

@AkivaWeinberger cool

The gh is cognate with /γ/ in related languages

I come from a tonal language and I'm not good at detecting stress

lol

Apparently Polish stress occurs mostly on the penultimate syllable so

@LeakyNun I keep on forgetting

Gonna go back to my video

my Polish friend says it's the second syllable

@ÍgjøgnumMeg @AkivaWeinberger

OK

Euclid's algorithm can be thought of as filling a rectangle with squares.

Milnor's exotic spheres can be thought of as black magic algebraic fuckery

@Balarka @Akiva et al: For your amusement.

Added minor formatting changes (and a $\frac{ds/dt}R$ that I think makes things clearer)

The original formula seems related the derivative of the arccosine

I lost interest with the sloppy notation and the condescending attitude.

The OP didn't even know what $\theta$ meant.

We are getting some extremely weak posts in differential geometry these days. Extremely.

I told this guy twice that he needed to restrict his map to the tangent plane, and he totally ignored me and posted the question a second time.

I wonder if that happens to everyone. Like imagine Terence Tao getting condescended to about analysis

No, I highly doubt anyone would condescend to Terry Tao.

I'll be honest it doesn't look so condescending to me

The last comments from that guy don't look condescending?

Well, maybe if they didn't know who he was

He confused $\theta$ and $d\theta$

No, he confused all sorts of stuff.

I asked him to explain that $d\theta/dt$ formula with no limit, $x$, and $h$ in it twice or three times.

I suspect Ted was talking about this comment in particular: "I thought the concept was relatively simple, if you search up curvature on this site you’ll find some helpful posts that may allow you to understand the formula in my post."

Yes, that one will do.

I will be infinitely patient with people who read and make serious efforts to communicate, but when people insist on restating the same thing without even trying to understand what I say ... I'm not patient.

Whoever they are, they're thinking the lack of understanding with what they wrote is because you don't know the subject matter, as opposed to them writing the formula incorrectly. That's indicative of a blind spot towards themselves
