[Some analogy]

Frequentists are like people with perfect knowledge. The probability distribution never changes
Bayanesians are like people with imperfect knowledge. The probability distribution updates based on the outcomes of the experiment as it accumulates

Both views will coincides once a suffciently large number of trials are taken, that way, any new outliers can only shift the bayanesian probability distribution a little due to (something related to) law of large numbers

This also explains how under the bayanesian model, it can be easily misused. The quality of the probability distribution depends on the quality of the evidences, thus garbage in garbage out principle applies

ugh

@skullpatrol Why did you move those comments to the trash?

@JohnRennie going home for a couple weeks

should I take lots of books so I have options or take a small number of books so I don't procrastinate

John Rennie

I'd probably take only the books I really want to read ...

Though the Internet has made procrastination easy under all circumstances :-)

Loong

0celoñe7

Lately I've taken to procrastinating via starting a half-dozen projects, then deciding it's too much and playing a video game instead

Why did you people let me get a gaming PC

@0celoñe7 Don't worry. Even playing video games will increase your country's GDP. ;)

1:45 PM

@heather that's exactly what I used to feel few years back. Then, I simply began missing friends in high school

djsmiley2k

@Loong Yey, the night comes sooner!

@0celoñe7 Me too, yus

Without games, I'd likely have killed my self with a diy project by now

Sid

@0celoñe7 For doing exactly that! Don't you know, all of us here are conspiring against increasing USA's GDP? :P

Loong

@djsmiley2k In my case, "oh, the night comes back"

Sitting in a bus, according to a display it's three hours later than it actually is and the temperature is 85°C. I hope I survive this.

djsmiley2k

an object faster than the speed of light eh

it'd still be visible lol

just, not at where ever it is XD

heather

@ACuriousMind 185 degrees F!?

Sid

@ACuriousMind ... 85 degrees celsius?

Holy crap.

heather

i hope that display is wrong =P

djsmiley2k

that's .... deadly heat

ACuriousMind

2:15 PM

The display is most certainly wrong, since I can breathe without cooking myself :P

djsmiley2k

^^

that's your skin is starting ti stiffen

Sid

must be 85 degrees fahrenheit

djsmiley2k

suddenly I have visions of randall of xkcd making a graph of what happens to humans at various tempretures

Sid

In which case, it is cold

djsmiley2k

@Sid or it's engine temp

Sid

2:16 PM

Or that, of course. ^

djsmiley2k

I don't know where @ACuriousMind is located tho...

Sid

They claim to be in Germany, I think.

djsmiley2k

> I'm currently a student of physics at the University of Heidelberg

indeed.

No parts of Germany are naturally 85C right now.

heather

@ACuriousMind might be vacationing

djsmiley2k

welp TIL that puncture resistant tyres really aren't that expensive.

heather

2:18 PM

djsmiley2k

Now this makes me want to try riding again.... i'd always end up stopping/giving up any kind of regular riding, simply because punctures...

@heather infact how warm does the Moon get during daylight?

> When sunlight hits the moon's surface, the temperature can reach 253 degrees F (123 C). The "dark side of the moon" can have temperatures dipping to minus 243 F (minus 153 C)

heather

123 degrees C, approximately, according to google

beat me to it =P

ACuriousMind

@heather sort of - going to my hometown right now and then to Wacken next week

@Sid wot

Sid

2:35 PM

@0celoñe7 well, that's cold for Indian summers. But, yeah. Around this time, the temperatures are similar

user228700

Hey, everyone :-)

0celoñe7

are you at college yet

@BalarkaSen what are you learning?

Balarka Sen

hi

user228700

@0celoñe7 Who, me?

Balarka Sen

3:40 PM

@0celoñe7 not much

workshop ended today

0celoñe7

@Kaumudi.H yes

@BalarkaSen What did you learn?

Balarka Sen

not much

it was mostly analytic

user228700

No, I'm at my grandparents' place, which is a few hours away from college. Orientation is on Tuesday.

0celoñe7

@BalarkaSen So went over your head/just didn't care?

Balarka Sen

Nah, I did pick up a few things.

I learn some Riemann surface theory, hyperbolic geometry of surfaces, dynamics on negative curvature manifolds, etc

0celoñe7

3:43 PM

Do you have a reference for the third?

Balarka Sen

I was told Rufus Bowen has a book

0celoñe7

@BalarkaSen So it was ergodic theory?

Balarka Sen

yup

0celoñe7

I have ergodic theory on negative curvature on my list already. The list is ridiculous

every time I talk to my advisor he tells me to read two more books

I don't know how @ACuriousMind never reads books

Balarka Sen

he's a effing bot m8

0celoñe7

3:48 PM

@BalarkaSen So where are you in dC?

Balarka Sen

still need to learn Jacobi fields

0celoñe7

@BalarkaSen Ah, I did want to talk to you about curve geometry

@BalarkaSen We have a smooth embedded curve $\gamma:S^1\to\Bbb R^2$. Does the term "normal angle" mean anything to you? I think it's the angle to the $x$-axis of the inward pointing normal vector.

Balarka Sen

Could be. I have never heard of that terminology.

0celoñe7

Call that angle $\theta$. If $\gamma$ is convex then apparently one can parametrize the curve by that angle. I'm willing to believe that.

Balarka Sen

Should def be right

0celoñe7

3:53 PM

Convex meaning either the curvature is always positive or the curve bounds a convex subset of the plane.

(I'm pretty sure they are equivalent, we've talked about that.)

user228700

@BalarkaSen Clearly, I have given up on the idea of reading Notes from Underground before my college starts :-/

0celoñe7

But then one has $$(\frac{d\gamma}{d\theta},\vec t)=\frac{1}{k}$$

this guy doesn't explain the notation

I think $\vec t =d\gamma/ds$, where $s$ is arc length

0celoñe7

@BalarkaSen what?

@Kaumudi.H He is the most famous Indian in America

user228700

Most famous living Indian, perhaps; Gandhi's gotta be the most famous Indian in America if you're allowed to count the dead as well.

Balarka Sen

nah

user228700

Who, then?

0celoñe7

@Kaumudi.H ok, living Indian

Balarka Sen

Yeah you're wrong

Way more people recognize Ghandi than NAV

Balarka Sen

huh

oh well

0celoñe7

4:12 PM

But I don't know any living Indians

Besides NAV that is

And I represent a cross section of America pretty well

@0celoñe7 You know R. Shankar, don't you?

this is my favorite rap song by the way: youtube.com/watch?v=unRldLdllZ8

i am not sure if i mentioned that before

user228700

You haven't, no x'D

user228700

@0celoñe7 And you "know" us; we're both "living" Indians.

Balarka Sen

I do not identify myself as an Indian

0celoñe7

4:16 PM

@Kaumudi.H I have his quantum mechanics book

If that's what you're talking about

user228700

That is, yep.

0celoñe7

But there are far fewer people who know quantum mechanics than mainstream rap listeners

user228700

@BalarkaSen ...you don't?

0celoñe7

@Kaumudi.H (a) I don't know your name (b) I don't really know you're Indian

user228700

What do you mean by "I don't know your name"?

Balarka Sen

4:18 PM

@Kaumudi Nope. Not to show any disrespect towards the nation of India or a generic Indian, of course.

user228700

Why not?

Balarka Sen

I do not identify myself as a member of this Earth.

user228700

@0celoñe7 Oh, that's a stupid argument; I'm sure you know lots of people in your real life whose full names you don't know.

user228700

@BalarkaSen I seriously wonder why he is bidding goodbye to everybody in his life using his cell phone.

Balarka Sen

@Kaumudi Most importantly, the background behind him is warping while he's doing that

Skyrim, DOTA 2 and Rise of the Tomb Raider (on a really good computer, purely to experience what can be done with a good graphics card nowadays)

@BalarkaSen I have brought The Age of Reason here with me and I hope to read it slowly in the coming months.

0celoñe7

@Kaumudi.H just don't do it

@Mithrandir24601 Skyrim doesn't need a really good computer

I am modding the hell out of it and it makes my GTX 1080 work though

user228700

@BalarkaSen Very nice (:-P).

Mithrandir24601

@0celoñe7 No, neither does DOTA 2 :P I meant that you need to play Rise of the Tomb Raider on a really good computer, for the graphics

0celoñe7

4:40 PM

@Mithrandir24601 How long is that game?

I'm getting pissed off by really short games lately

Not that I need moer games

by cheap, i mean less than the $45 I've currently seen as the lowest porcelain-steel one on amazon

@Dovah-king hello

Dovah-king

in the country you guys live (i'm assuming its USA) how is the reputation of engineering physics/engineering science? i mean, if you work in industry, how is engineering physics known to it? or in the academic field, how is engineering physics seen by the physics academical comunnity? thanks

heather

well, engineering jobs in industry here pay pretty well. i don't know exactly what you mean by reputation...

Dovah-king

i mean,

engineering physics is relatively new in my country... the industry doesn't "know" it well

heather

10:26 PM

ah. I'm not sure I'm qualified to respond to your questions =) I'm a highschool student, so.

Anonymous

@Dovah-king Engineering physics is basically a physics degree with focus on application. It is a fairly new stream almost everywhere. By jobs...if you look for engineering based jobs there are plenty. However "physics" jobs are quite less in number unless you wish to stay in academia or say want to be a professor.

Dovah-king

@Blue

Thanks

Anonymous

@Dovah-king Where are you from ?

Dovah-king

but my "seen by the physics academical community" was like: we know that physicists doesn't very much engineers in terms of speaking about science in general (btw i'm okay with that). Do you think that an engineering physicist

will have a little more "authority" when speaking of scientific research?

oh btw im from southern brazil

DanielSank

@heather cannot

Good boards are expensive.

heather

10:32 PM

=/

DanielSank

@Dovah-king I'm not sure what you're asking. I have a PhD in physics and now I work in a lab at a company.

heather

i really prefer chalkboards over whiteboards, but maybe a whiteboard would be better, just in terms of the chalk dust...

and whiteboards do seem to be cheaper.

DanielSank

@heather me too. There was some kerfuffle about this when we set up the quantum lab in Santa Barbara...

heather

guess i'll have to think about it.

Anonymous

@Dovah-king I don't understand your point. Your "authority" depends on your knowledge and your research experience. I've seen so many engineers who have gone on to do great amount of research in physics. And yeah, an engineering physics degree should help you if you wish to do physics research...as it is just a physics degree! (NOT a core engineering degree)

Dovah-king

10:45 PM

Thanks!
