The apple $1$-form

0celo7

@Slereah quite nervous about this talk

it's going to be horrific

Shing

the second answer claims Norton's Dome is wrong (the basic idea behind Norton's dome is quite solid to me though) , but i can't be sure whether if it is right or wrong, would anyone be kind enough to help me here?

@BalarkaSen @0celo7 Infowars has weighed in on click click ugandan brudda

Balarka Sen

sigh

Slereah

16:20

@0celo7 you seem to know your stuff

Phase

I gotta be honest

Balarka Sen

I stopped after 5 minutes. I can't listen to PJW

Phase

I like edgy comedy sometimes but

yeah

Balarka Sen

That guy is a shithead

Phase

PJW is the definition of a pleb

I've never enjoyed his content

I think Chris Ray Gun is a much more entertaining guy

Balarka Sen

16:21

Idubbbz2 is great

Slereah

@Shing He's not very convincing

Balarka Sen

love 'em

Slereah

The value at the 4th derivative isn't really relevant to the "newtonian" character

Phase

Thing is

his forehead isnt big enough to be idubbbz2

Slereah

I mean it's not a very realistic system

But still

Balarka Sen

16:22

He doesn't have that receding hairline

CooperCape

I just failed an organic exam :D

Slereah

there's nothing non-Newtonian about it, unless you specify what a Newtonian system is to exclude it

My favorite non-deterministic Newtonian system is the Space Invader

Which is much cooler

Phase

@CooperCape I just failed an exam too

So we can be flunky buddies

Slereah

although it's even more pathological

since it has unbounded acceleration

CooperCape

Ooh yay! Although the I imagine yours are more important...

Mine was just a mock ygm

Slereah

16:25

(the space invader has no particle at $t < 0$ and one particle at $t > 0$)

Phase

mine was a semester 1 exam of a module I paid no attention to

my plan was to wake up 6 hours early and learn the content

I woke up 30 minutes before the exam

CooperCape

Ahh right

Bit awkward then

How does it rate on the affects your life scale?

Phase

in terms of the course? prolly not that high since I can prolly resit at some point but

on the kill'myself'o'meter it's a whopping 10

CooperCape

Ahhhh dang

See I’m still at the point where my mums gonna kill me for me but w/e

Phase

is there a reason for your fail?

Like, a systematic error you kept repeating or just not sleeping before the exam etc

CooperCape

16:29

I didn’t revise enough - completely my fault.

I just didn’t have a clue.

Phase

best of luck in the real thing

CooperCape

I mean what does test for a ketone anyway

I know what doesn’t.

Phase

Idk don't ask me I hate chemistry

HsMjstyMstdn

Hello everybody ! How's everyone doin

CooperCape

Yeah thanks :p

You too for whatever you may have (idk uni system)

Balarka does organic chemistry right?

Phase

16:30

I mean I shouldnt need the luck hopefully

because the second half of the module seems to just be basic Linear Algebra

CooperCape

Ooh neato

HsMjstyMstdn

Balarka does a lot of things.

CooperCape

So I should wish you a good nights sleep and an effective time to wake up.

Phase

Prolly considering this exam I woke up too late to learn the material and last exam I didnt sleep the night before

the last exam was prolly around 80% tho so I didn't mess that one up nearly as much

CooperCape

Ooh that’s good then

My mock periods been kinda meh but it’s over mow

At least physics/maths went well

Phase

16:33

as long as you learn from the mistakes then it's all good

Good good

dont get complacent tho xd I did well in the mocks, got complacent and screwed up the real things

0celo7

@Slereah they messed up the abstract on the announcement

CooperCape

Ouchie... then again I don’t think that’s a problem due to the ‘doing well’ requirement ;). I do need to do alrighty though cause the offer I want to go with (Manchester) is AAA and it’s like ehhhh

A* maths should be fine it’s just physics is a bit less so

Phase

Im gonna assume that

you need A star A star A

: P

CooperCape

Oh did it fuck up

I forgot to backslash smh

But yah

0celo7

@Phase I finally got that money

Phase

16:40

what money

oh

your sister?

@CooperCape its more the fact that two stars makes things italics, so instead of A star A star A you made A slanty A A

@0celo7 can you help me understand this: "Indeed let $E$ be a basis for $V$. Elements of $V^*$ correspond bijectively to functions from $E$ to $k$, while elements of $V$ correspond to such functions with finite support." what does it mean by "such functions with finite support"?

also why does he say that an element u in V* is such that $u:E \to k$ rather than $u:V \to k$

John Rennie

@SirCumference correct. A collapsing universe is just the time reverse of an expanding universe and both can be infinite.

0celo7

Finite support means the function is not zero on only finitely many elements.

Sir Cumference

@JohnRennie Why is that?

John Rennie

@SirCumference why is what?

0celo7

@Phase a linear functional is determined by its value on a basis

Balarka Sen

16:48

Expansion is a notion of changing metric, not "expansion of the topological space"

The topology can be the same, but the metric can be ever increasing

Shing

okay, I come up a kind of crazy question about rotating when we rotate a paper along z, the direction z is outside of the paper (not within the 2-D plane) ; however, when we rotate an apple, the direction is within our 3-dimensional world. Does it mean we have two kinds of rotations?

Phase

@0celo7 nonzero on finitely many elements...? confuse

Balarka Sen

You can have a metric on $\Bbb R^n$ such that distance between $(1, 0)$ and $(0, 0)$ is $10^{-10^{10}}$

The space is still "not compact"

@JohnRennie Why did you delete that?

John Rennie

@BalarkaSen I thought you were commenting on SirCumference and my conversation when I saw the word expansion

Balarka Sen

I was!

Phase

16:52

@JohnRennie when is the photo on your profile from btw?

John Rennie

Ah, OK :-)

@Phase mid 1990s I think

Phase

Why the black and white? :0

Balarka Sen

only 90's kids would remember it was all black and white then

John Rennie

@Phase It's scanned from a B/W photo. We didn't have smartphones in those days :-)

Phase

wait

Was photography really black and white in the 90s?

0celo7

16:55

No...

John Rennie

No

Phase

I didnt think so

Balarka Sen

you fell into my trapp

Phase

Balarka i trusted you

last time I trust a commie

Balarka Sen

use homeomorphism to escape

Phase

16:55

no homeo

John Rennie

I've just come back from watching The Last Jedi BTW

Balarka Sen

so you have witnessed Ben Swolo?

0celo7

@BalarkaSen interesting theorem: there’s only one group up to homomorphism

CooperCape

Yo Balarka do you know what tests for a ketone

Like I know what doesnt

0celo7

@JohnRennie not good movie

Balarka Sen

16:57

@CooperCape Hmm

John Rennie

@0celo7 I enjoyed it. Not the greatest film of all time but good fun.

Some cheese, but that's what we expect from Star Wars.

Phase

do I need to see rogue one

Balarka Sen

@CooperCape Let me check my textbook. I need to study aldehydes and ketones actually

Phase

like is it a prereq for last jedi or is it a spin off

CooperCape

I know tollens/fehlings is aldehyde/carbonyl (I think)

John Rennie

17:00

I'm told Rogue One is the most grown up of all the recent Star Wars films.

i.e. less flash, bang, wallop and more thought.

Though actually there are some serious points in The Last Jedi if you take more than a superficial look.

0celo7

THE SACRED JEDI TEXTS was so lame

Luke is a lame Jedi in Disney’s adaptation

John Rennie

That's precisely why Yoda burned them

0celo7

Yes, Yoda was good

Snoke was lame

Garbage villain

Balarka Sen

@CooperCape Aha. CH3-CO-CH3 + I_2(aq) --NH4OH+$\Delta$--> CHI3 (iodoform) + other stuff

Phase

I wasnt a big fan of force awakened tbh

Balarka Sen

17:04

It's an iodoform test. CHI3 is yellowish

and has a distinct smell

John Rennie

The Jedi texts are all over the various Star Wars novels, in various degrees of pretentiousness, so I thought burning them was a good statement.

vzn

in theory salon, 1 hour ago, by vzn

AlphaGo documentary / imdb ← outstanding! :)

0celo7

@JohnRennie I don’t disagree, I think Luke was very lame in this movie

vzn

↑ saw it yesterday, great for CS geeks

0celo7

The plot is basically just the OT

And the Asian girl was a completely unnecessary addition

John Rennie

17:08

Well it's not my film or your film. It's Disney's film and we can take it or leave it.

vzn

@0celo7 express.co.uk/entertainment/films/893445/… variety.com/2017/film/news/…

Balarka Sen

Disney always sucked anyway

John Rennie

But I still enjoyed the couple of hours I spent watching it. I didn't feel the time dragged at all.

0celo7

I watched it twice. Was better the second time.

John Rennie

Blade Runner 2049 is the best film I've seen in the last year, and by a long way.

0celo7

17:10

Mark Hamill is one of those comical anti trump people, it’s hard to take him seriously

Slereah

Last day of broken heater, hopefully

Repairman arrives tomorrow morningh

vzn

@JohnRennie :) top of my list also. what did you like about it?

@0celo7 again hard to figure out if you are serious :P

Balarka Sen

2017 produced a lot of campy science fictions

I think Get Out was my favorite horror movie from that year

John Rennie

Get Out

Get Out is a 2017 American horror film written and directed by Jordan Peele. It stars Daniel Kaluuya as Chris, a black man who visits the family of his white girlfriend (Allison Williams); at their home, the servants are black and act strangely. Bradley Whitford, Caleb Landry Jones, Stephen Root, Lakeith Stanfield, and Catherine Keener costar. Get Out premiered at the Sundance Film Festival on January 24, 2017, and was theatrically released in the United States on February 24, 2017, by Universal Pictures. The film received acclaim from critics and audiences, with praise for Peele's screenplay and...

That one?

Slereah

I got the book of papers from Nambu

A lot of them are a snooze

Balarka Sen

17:16

Yep @JohnRennie

Slereah

"A note on the eigenvalue problem in crystal statistics"

snore

bolbteppa

Apparently everyone overlooked Nambu, he ended up with a nobel at least

Those string papers are not as good as I was hoping from skimming

Slereah

Nambu isn't the worst, really

I almost never heard of Veneziano

Balarka Sen

it seems this is the movie that won the Golden Bear

On Body and Soul

On Body and Soul (Hungarian: Testről és lélekről) is a 2017 Hungarian drama film directed by Ildikó Enyedi. It won the Golden Bear in the main competition section of the 67th Berlin International Film Festival. At Berlin it also won the FIPRESCI Prize and the Prize of the Ecumenical Jury. It was selected as the Hungarian entry for the Best Foreign Language Film at the 90th Academy Awards, making the December shortlist. Alexandra Borbély won the European Actress award at the European Film Awards for her performance in the film. == Plot == Endre and Mária work together in a slaughterhouse and have...

might be worth watching.

Slereah

even though he's one of the founder of string theory

John Rennie

17:21

@Slereah you need more amplitude then

Slereah

oscillates harder

bolbteppa

I feel like I'm close to seeing where Venenziano comes from, close as in months

Slereah

From Venice

it's in his name

bolbteppa

This is the second time Italy has stalled me, really want to google-translate an old Levi paper but keep giving up on that too :(

Slereah

Mama mia

I've had that problem too

Although it's not that bad since italian and french are pretty similar

good thing I don't need to read japanese papers

bolbteppa

17:29

We probably do and don't know we should

Slereah

Usually the untranslated papers of interest are in French, German or Italian

Maybe

But I never saw a reference to a japanese paper

I've seen russian papers once in a while

But never any other language, really

bolbteppa

Yeah me neither, R, F, G, I is all I think I've been stuck on

Slereah

I've seen a portuguese paper once

bolbteppa

I would call those old Mach books etc yee-olde English in a sense which is off-putting

You only buy the Principia when you don't know any math and think 'this is the bible right'

Slereah

Eh

19th century isn't too bad

Really old papers are even worse because they're mostly in Latin

Phase

17:32

Imagine if they uncover an old caveman ruin with wall paintings but on one of them there's the proof of the Riemann Hypothesis

That would be the best timeline

Slereah

so it turns out it was the key to successful mammoth hunt

Phase

The cavemen were so primative though

They wrote "$1 + 2 + 3... = \frac{-1}{12}$"

Truly an undeveloped and barbaric time of our history

Slereah

IIRC the only caveman math to survive is like

tally marks

Phase

Idk

The equivalence principle was useful for when they tried to throw spears to kill things in elevators

Slereah

Caveman math

"the Ishango bone is a bone tool"

heheh

Phase

17:41

Idk I dont believe its to do with maths

Slereah

for some reason a lot of them are on bones

Very caveman like

Phase

It was an honest time

and then capitalism came along and the cavemen had to learn marketable skills

Slereah

Phase

Tusks?

Balarka Sen

@Phase That's what I have been telling people all along

Slereah

17:43

Bushpig tusks, yes

Phase

I wonder what the first vocal argument was about

When language was first becoming advanced

"me stick better"

also thats a pretty cute pig

Balarka Sen

:indistinct screeching:

Phase

@BalarkaSen did they know about tendies?

Balarka Sen

they probably did not invent english right off the bat

Slereah

BIGGEST ROCK IS BEST ROCK

Phase

17:44

"me have tendies REEEEEEEEEEE"

I'd love to also know what the first religious concept that appeared was

So many questions that are impossible to know the answers to feelsbadman

Slereah

one common theme I noticed in hunter gatherer societies is that they really hate anyone thinking he's better than everyone else

if you get a bit too cocky everyone starts mocking you

Balarka Sen

Karl Marx influence

ACuriousMind

@Phase Burial rites are very ancient

Slereah

Catholicism, obviously

ACuriousMind

That is, we've found graves with items in them that are much older than any account of "civilizations" as we might know it

Slereah

17:47

cave catholicism

Did anyone have a religion in the Flintstones?

They did celebrate Christmas

So I guess they were all cave christians

vzn

my favorite are the ancient venus statues :)

Slereah

you like them thicc?

vzn

lol what is thicc? dailymail.co.uk/news/article-5259615/…

Slereah

please don't post smut here

vzn

lol ~~smut~~ art

Balarka Sen

17:59

i only consider mutilation and murder as art

vzn

@BalarkaSen aka cronenberg ... did you ever see dead ringers? o_O

Balarka Sen

Yes
