@Mithrandir24601 perhaps, this may help

Droleulb

@0celo7 get on dc :'(

@skull It does actually, thanks! :)

skull

np, good question :)

Changing history = simultaneous rearrangement of events in a section of a worldline

Obviously took a lot of energy to do

Perhaps the flip flop state of a grandfather paradox in type 3 universes can be stabilised by expending extreme amounts of energy so that the time travelling act will not be erased from existence by creating a singularity at the point of departure while preserving the altered history

more investigations on the plausibility of this later

Important question

should I write the sphere as $S$ or $\mathrm{S}$

skull

why is it so important?

Slereah

Aesthetic

skull

whichever appears more pleasing to you

Slereah

I was born without a sense of beauty

very rare disorder

skull

12:17 PM

then it's time to correct that

after all, it is in the eye of the beholder

Slereah

I was born without eyes

very tough

I learned $\int_a^b f=F(b)-F(a)$ in kindergarten

wut

$$\int e^{\%} = \%$$

$$\int e^{e^{e^{\%}}} = e^{e^{\%}}$$

@Slereah stuff like this i.gyazo.com/79beed5b9b3f29f488476a3e29d0b2b9.png

Slereah

where is physics

0celo7

adm mass

Slereah

But that's the bogus Riemannian ADM mass

0celo7

wow, mean

Slereah

Is there a name for like

a warped product

but instead of a product, the manifold is a bundle

@bolbteppa Thanks for sharing :)

Semiclassical

2:19 PM

the post-defense brain drain is real today

Slereah

how did it go

Semiclassical

good enough

some obvious stumbles, and definitely points where I could have been clearer about the setup

but, good enough

Swapnil Das

@0celo7 I just wanted to ask, is there something like Theoretical Reactor Physics

?

Loong

2:37 PM

@SwapnilDas Do you mean like a book?

Swapnil Das

No, a field of study

I wanted to know if Nuclear reactor Physics is all about experimental work or else has some Theory.

@JohnRennie Any idea^^ ?

John Rennie

@SwapnilDas you mean reactor design?

Swapnil Das

yes

John Rennie

That's really engineering.

Its well understood physics, but the systems you're working on are complicated.

Loong

@JohnRennie and politics. :-|

Slereah

2:44 PM

how come the site with the Feynman quote in the starboard also has this : genius.cat-v.org/eric-cartman

and it's not like a huge quote website

Swapnil Das

Is there anything like Computational nuclear physics?

@JohnRennie

John Rennie

@SwapnilDas As it happens a friend of mine works in reactor design studying heat flows in reactors. He does mostly compute modelling.

Slereah

there's only 15 people quoted

It seems an odd sample of people to quote

Swapnil Das

@JohnRennie I see. Do they do any hands on stuff or just computers?

Slereah

I have passed 7000 points

hurray

3

John Rennie

2:45 PM

@SwapnilDas I think it's pretty much all computer modelling.

Slereah

3000 left and I have the Power

Swapnil Das

I wanted some career advice.

I wanted to work in Nuclear Physics, but I like Theory rather than experimentation. What should I study, then?

Slereah

Nuclear physics

there's plenty of nuclear physics theory

Swapnil Das

That I also know :P

@Slereah Is that as competitive as string theory?

I have heard that many nuclear Theorists work in the industry. Is that a career transition or do they have something of their relevance?

Loong

I don't know any real nuclear theorists in the industry. Most of the people here are engineers.

Swapnil Das

2:52 PM

I see.

Slereah

Nuclear theorists work more at like

accelerators

Like the nuclear accelerator in France, I forget the name

Possibly SPIRAL2

SPIRAL2

SPIRAL2 (Système de Production d'Ions RAdioactifs en Ligne de 2e génération) est un projet de faisceaux exotiques pour la recherche en physique nucléaire fondamentale et interdisciplinaire au GANIL. == Explications == Il est basé sur un accélérateur linéaire de particules, le LINAC, qui fournira[Quand ?] des faisceaux d’ions stables de très hautes intensités. Les réactions induites par ces faisceaux stables dans différentes cibles de matière produiront des noyaux exotiques à des intensités inégalées. Ces noyaux exotiques (non présents naturellement sur Terre) permettront aux physiciens d’étudier...

that's the one

except very French

Swapnil Das

@Slereah So accelerator physicists can be theorists?

Slereah

Sure

You use the various nuclear models to predict reactions

Swapnil Das

Aha!

Slereah

and then test those predictions

Swapnil Das

2:54 PM

That's something exciting

Slereah

As exciting as the nuclear N-body problem can be

Swapnil Das

No hands on work right? ( Asking just bcoz I hate it )

@Slereah Fundamental physics is competitive, you know.

Slereah

Tell me about it

Swapnil Das

about?

Slereah

it is a figure of speech

Q: Why does "tell me about it" not mean "tell me about it"?

A commonly used American phrase, but one that still baffles me if I stop and think about it. Why does "tell me about" actually mean, "I understand what you're talking about as I have experienced it myself". Not only are you not literally inviting the person to go into more detail, but (most confu...

as u can check from StackExchange

Swapnil Das

2:57 PM

Aha

Thanks.

[Random]

Swapnil Das

Well, do you know any famous accelerator physicist , who is a theorist?

Secret

What if the Theory of Everything is just a whole bunch of accidents and cannot be expressed in nice equations

Swapnil Das

@Secret No problem. The journey will be rewarding :)

Slereah

Warped manifold papers are all in math people tensor notation

very bad

Secret

3:06 PM

$T (\otimes \otimes \cdots)$ stuff?

John Doe

@Mithrandir24601 Hi how's it going? Short QMT question: When describing a general quantum measurement. Do you have an idea of what is meant by "the pointer states are in fact determined by the requirement that different measurement outcomes decohere via interaction with the environment?"

0celo7

3:27 PM

@Slereah 3 Yvonne citations

Wonder if that's all I'll need...
