If that's what you think goes on in there, your impression of it comes through a hugely biased filter in terms of stuff that gets a lot of visibility but isn't a huge part of the profession

seriously, seek out opportunities for science busking

it's great fun, looks good on a CV, and you learn a good bit about yourself in the process

Mithrandir24601

@EmilioPisanty Science busking is one of the things that I'm just not good at...

Emilio Pisanty

@Mithrandir24601 its' not for everyone, that's for sure

but you won't know until you try

Mithrandir24601

Yeah, it's definitely worth trying - even I wasn't totally useless after 2 hours of solid practise

is quantum computers a hoax ?

what is the current situation of the research?

All the media seems to be over hyped about it. Can someone explain?

anyone knows about Constructor Theory? It looks pretty cool.

Phase

@EmilioPisanty idk if I agree with the principles of it though. It effectively seems to be just like what I dislike about pop-sci, boiling physics until the maths and consistency turns to vapour and sharing the 'cool facts'

at least, that's the vibe I got from sciencemadesimple.co.uk/shows/busking

Besides, I'm only first year it would probably be pretentious to go around campus / anywhere IRL doing this

Mithrandir24601

@PiyushDivyanakar Not at all, but it most likely is overhyped by the media - I'm going to be honest and say that I don't think we'll have a fully scaled up quantum computer for a few decades. Current research is that IBM has 17 qubits and Google's working on a machine with ~50 qubits, which they say will be finished by the end of this year. For a fully scaled up one, we need somewhere around millions of qubits at least

Although it's possible they'll be useful somewhere not too far past the 50 qubit mark

(i.e. <100 qubits would probably be useful to science research in some way. ~500 would be useful for science research, as we can then have a decent number of error corrected qubits)

Lol, you have no say if you say entropy is a measure of disorder

Phase

@Secret i think you either have to be Ok with pop-sci existing and accept that no-one can expect a non-student to invest the time to understand the terms rigorously or properly, or refuse all forms of Pop-sci. I don't think this is a particularly stand-out case of being very bad

Secret

Well, at least for entropy, there is a way to explain it better. One common and reasonably accurate explanation is that it is the number of ways to arrange things that satisfy some given macroscopic properties

Phase

im sad

i cant find my drawing tablet anywhere

:(

Mithrandir24601

@Secret I'd argue that properly explaining entropy is complicated enough that physicists that say this are just putting all the complicated details into this word 'disorder' and giving it a complicated meaning, only because most people know the word 'disorder', they're not aware of this

It's back to the "x is a measure of y. OK, that's great... What's y?"

Abcd

@Secret Yes, $S = k\ln w$ where $w=$ number of microstates available.

Secret

10:09

The problem is that 'disorder' is vague enough that a lot of misconceptions arises from it, including the notion where people get really terrified by the misunderstood idea of the second law in that 'everything is getting worse and more disorderly', while in fact the second law is neutral as it is also what drive many life processes

Mithrandir24601

@Abcd Even that only applies in certain scenarios and requires understanding of what 'microstates' are - I much prefer $S=-\sum_i p_i\log p_i$, which is clear, to the point and, best yet, is the definition at any level

Piyush Divyanakar

The D-Wave systems is currently manufacturing commercial quantum computers. It is advertised as 50 qubits. Is it a true quantum computer.

Also I wanted to know if there are any review papers that I might read to get upto speed on the technology currently available for making qubits.

Phase

@PiyushDivyanakar does it run Skyrim?

Mithrandir24601

This also has the added bonus that it makes it clearer that entropy is just another way of saying that a system will tend to end up in the most likely arrangement of that system (i.e. the arrangement with the highest probability of occurring), which shouidn't really come as much of a shock :)

Piyush Divyanakar

@Phase If it did our will our instructions be executed all the time.

Secret

10:13

@Mithrandir24601 That equation is also cool because it allows people to be aware of the relation of entropy with information

Piyush Divyanakar

Also will the consequences of our actions be deterministic

Mithrandir24601

@Secret Exactly :D

@Phase did you try calling it

Phase

10:18

It's a drawing tablet

:(

Mithrandir24601

@PiyushDivyanakar Do you have a link for this? They do have a ~2000 qubit processor, but it's a non-universal machine and isn't fully connected (i.e. every qubit can't immediately interact with every other qubit). It can be used to give a fully connected 64 qubit 'graph'. I also wouldn't be remotely surprised if they've got a universal machine with a number of qubits. I might be a tad surprised if they admitted it though...

Fawad

Hi!. Why only monochromatic light is used for photoelectric effect?

Phase

It's monochromatic at any one point but you tend to go through a continuous spectrum

Until eventually you find one that liberates electrons with minimal kinetic energy

and then as you increase the energy of the photons after that point

it leads to the emitted electrons having more KE

Since $E_{electron} = h\nu - \Phi = 0.5mv^2$ where $\nu$ is the frequency of light and $\Phi$ is the workfunction [energy required to liberate an electron]

Piyush Divyanakar

@Mithrandir24601 I was guessing i didn't remember the exact value. I have gone through their tutorial and the types of problems it can solve seems very narrow, doesn't it?

Mithrandir24601

@PiyushDivyanakar Compared with what we're used to with normal computers, yeah

Piyush Divyanakar

10:29

@Mi

@Mithrandir24601 is there a cloud version of d-wave available. Like can we run d-wave code and get results?

Mithrandir24601

@PiyushDivyanakar You can't run things on D-Wave, but they've written a program for programming it and it defaults to running a classical simulation - github.com/dwavesystems/qbsolv

(that program is open access)

Piyush Divyanakar

@Mithrandir24601 @Mithrandir24601 I have played around with this library.

Is this just a simulator? and not real code that can be run on a QC

Emilio Pisanty

@Phase Not necessarily

Fawad

@Phase 👍

Emilio Pisanty

@Fawad You don't have to, it just simplifies the analysis

The good thing is that it's a linear process

So, if you have light of more than one colour, then you just analyse the cases separately and the global response is the sum of the individual responses

if you have light at frequency $\nu_1$ and at $\nu_2$, then you're going to get electrons at energies $E_1=h\nu_1-\Phi$ and $E_2=h\nu_2-\Phi$

Mithrandir24601

10:42

@PiyushDivyanakar If you have access to one of their machines, you add a line somewhere at the top with a key that allows you to have access, so it's exactly the same code as if you were running it on one of their machines, only it's being simulated classically instead of actually being run on D-Wave

Piyush Divyanakar

okay

Fawad

@EmilioPisanty to simplify everything and study behaviour of certain frequencies on metals,we use monochromatic light.

Emilio Pisanty

@Phase There is indeed a bit of that. But communicating science in its full spirit isn't easy and it takes a lot of people skills. Busking helps build those ;-).

@Fawad if you're already "studying the behaviour of certain frequencies", you're already using monochromatic light ;-)

otherwise you can't talk about the frequency because you have multiple frequencies at the same time

but yes, we want to study the interaction of light with metals and to simplify the analysis we first do it frequency-by-frequency (i.e. we use monochromatic light) and then we combine the results

@Phase No, they take volunteers from anyone, GCSE and up

@Phase I'd avoid orgs that charge for their services though ;-)

Your department likely has an outreach officer, ask them if they do stuff

otherwise, say, IOP might have interesting opportunities

Q: Are there model 3D surfaces with star and monstar umbilical points?

The Wikipedia article on umbilical points classifies umbilical singularities into three types ─ star, monstar, and lemon ─ depending on the index of the singularity and the configuration of the lines of curvature around the singularity, and it also provides a nicely visualizable 3D model o...

any ideas?

Slereah

Not a clue

Emilio Pisanty

@Slereah =P fair enough

> any convex, closed and sufficiently smooth surface in three dimensional Euclidean space needs to admit at least two umbilic points

^ apparently that's still a conjecture?

man, mathematics is weird

Balarka Sen

yah

I have not thought about umbilical points a lot.

Emilio Pisanty

to be fair I don't particularly care about the umbilical points in differential geometry

Slereah

I think Penrose has a very short chapter on them?

Oh wait no, it was caustics

Balarka Sen

11:17

@Emilio I think the star umbillic appears in the Monkey saddle

Emilio Pisanty

@BalarkaSen yeah, that figures

the one that really stumps me is the monstar

I still struggle to understand how it's different to the lemon

Slereah

"It belongs to the class of saddle surfaces and its name derives from the observation that a saddle for a monkey requires three depressions: two for the legs, and one for the tail."

Emilio Pisanty

doi.org/10.1088/2040-8978/15/4/044027

^ the monstar in action in optics

Slereah

I assume monstar is short for monkey star

Balarka Sen

hm i don't see an easy example of a surface with monstar umbillics

Emilio Pisanty

11:25

> Green lines denote the streamlines of major axis of polarization ellipse. Under the control of $E_0$ they behave like the binary fission of a prokaryotic cell.

Balarka Sen

it's a bad version of lemon, for sure'

Emilio Pisanty

lolz

you can tell whoever wrote that really enjoyed it

@BalarkaSen yeah, it's bad for sure

Balarka Sen

I am not sure if the surface is supposed to be smooth at those points

It doesn't look very smooth to me

Emilio Pisanty

but the lemon has a singularity too, right?

and that one is completely smooth

Slereah

The citrusy black hole

Balarka Sen

11:36

@EmilioPisanty i mean sure but the lines of curvature in lemonstar doesn't seem to be smooth

or, hm, maybe i am misinterpreting

I guess the blue lines to the left are like $y = x^3$ for $x \geq 0$ and $y = 0$ otherwise

not entirely sure

Emilio Pisanty

@BalarkaSen yeah, those don't look very nice

but that doesn't mean the surface itself isn't smooth

@BalarkaSen well, the lines of curvature that pass through the umbilical itself do have a sharp kink there

Balarka Sen

Right, and that's bothering me

Hm, let's see. I think lines of curvatures are given by $\Bbb{II}(v, v) = 0$

No, that's an asymptotic curve, nevermind

@EmilioPisanty OK, this is what is bothering me; there seem to be three blue lines of curvature coming tangentially to the umbilic point. But lines of curvature are precisely the integral curves of the principal directions, and integral curves are uniquely determined by the initial tangential vector.

Emilio Pisanty

12:00

@BalarkaSen the initial tangential vector is obviously singular at the umbilic

it's the same deal with the star

once you're $\epsilon$ away then the line of curvature is unique

Curio

12:11

Two questions

The radiations which each body emits is different from the quantum jump

Isn't it?

0celo7

@BalarkaSen dunno what vid you told me about

0celo7

12:34

@BalarkaSen I found a tasteful quote: "Geometry is a magic that works..." - R. Thom

I put that on my thesis. It's probably better than Spivak's line about executing people

herbaman

Hey guys, is there anybody who could help me understand a (very basic) getDP.pro line?

Fawad

14:06

@0celo7 you are making your thesis 😲.

Balarka Sen

@EmilioPisanty Sorry, I don't get it. At the umbillic, every direction is a principal direction. But the lines of curvatures are still uniquely determined by the initial vector, right?

I think you should bring this up to Ted Shifrin in the math chat. He knows extrinsic differential geometry quite thoroughly, so would be able to answer your queries.

@0celo7 Oh damn it got deleted

It was so funny though

@Semiclassical The prof said someone made that choice long ago and now no one wants to change it because it might be catastrophic

Semiclassical

0celo7

Semiclassical

0celo7

0celo7

14:52

I am glad that the only time I'll ever worry about electromagnetism is in the context of Yang-Mills black holes.

Semiclassical

lol

it doesn't come up in nuclear physics, then?

0celo7

@Semiclassical It does, but the positive/negative crap isn't too important.

Semiclassical

I guess a lot of "electromagnetism" in practice is just electrostatics or magnetostatics

point

I don't really mean that too seriously, anyways.

electrons as charge carriers is the more common case, of course, but in solid state you h have the whole n-type vs. p-type thing. so you have to put up with charge carriers of various sign no matter what you do

0celo7

@Semiclassical In other news, my goal is to write a complete proof of the Yamabe conjecture for my thesis. My advisor wants me to include either the 1988 conformal embedding stuff or even the new proof of the PMT if possible

It's going to be a ridiculous thesis

Semiclassical

lol

That doesn't sound like just one proof

though i guess maybe it's more that you have to cover so many cases

0celo7

14:57

Yeah, the proof has a lot of aspects, although the overall idea is neat

Semiclassical

kk

not to sound like too much of a physicist, but

0celo7

And is very technical. My advisor and I agree that the standard proofs can be explained better, so there is something "original" here

Semiclassical

what's so interesting about Yamabe?

0celo7

@Semiclassical It's one of the few nonlinear PDEs that we know can be solved without hypothesis

And that's basically the statement of the conjecture

Semiclassical

hmm

0celo7

14:59

But the method is really interesting. It uses best constant Sobolev inequalities (known to mathematical quantum mechanics people) and the positive mass theorem (known to relativists)

Semiclassical

am I right in thinking that, for most nonlinear PDEs, the solutions we usually know are exact solutions

which are of course nice but are special

0celo7

Yeah and there are existence theorems for equations with "nice" nonlinearities.

Semiclassical

so Yamabe is sorta the reverse of that, where there's nothing particularly nice about the solutions but we know about them generically?

0celo7

pretty much

people have studied the solutions too, but the main conjecture was just that they exist

Semiclassical

along with the conjecture that one could prove they exist, heh

whereas I imagine for most nonlinear PDEs there's no such hopes

0celo7

15:03

@Semiclassical Well, I should point out that the equations are homogenous, hence have a solution trivially.

The real challenge is to prove the existence of a strictly positive solution.

And all of the usual methods fail there because they all just give SOME solution that doesn't change signs -- it could be identically zero.

So you have to work very hard to prove it's not identically zero.

Now on a bounded domain of $\Bbb R^n$ you can impose boundary conditions which are a pain in the ass for regularity, but are nice for existence because you know something about the solution.

But on a closed manifold the solution can be doing whatever.

@Semiclassical It's not wrong to say that the problem is interesting because it's so hard.

can you revert to a previous version that compiles?

vzn

@Semiclassical think he is way too hard on dwave, but he seems to have relented a bit after geordie rose ceo left, who do concede tended to hype stuff a lot. actually wonder if dwave has long term viability. ~$150M spent, not a lot of capability to show for it. (but qc is inherently very hard that way, not saying anyone could have done better!)

Emilio Pisanty

how easy is it to find that previous version?

@EmilioPisanty that's what backups are for.

I won't be making many structural changes now. I have the ToC in place, the page numbering figured out, and the bib in place.

Emilio Pisanty

15:43

@JohnRennie how often, realistically, is anyone backing up work?

once a week, tops?

twice a week?

Semiclassical

@vzn maybe. But I’m more inclined to be skeptical of such things in general

John Rennie

When I'm working on a project, e.g. the chem eng. stuff I do for the nuclear industry, I back up every day as part of the end of the day routine.

vzn

@Semiclassical qc skeptics have a lot to point at, but less so than just a few yrs ago. field is starting to gain traction...

Emilio Pisanty

@vzn Geordie Rose conceded that he tends to hype stuff a lot?

Semiclassical

The ultimate goal of a project like D-Wave may be have a working quantum computer on the market

John Rennie

15:44

You're now going to say you aren't typical. OK, maybe not, but anyone who doesn't backup every day is choosing to take the risk of data loss.

Emilio Pisanty

@JohnRennie that's way too sparse to recover a fucked-up latex fix

Semiclassical

But the immediate goal is “get enough money fro investors to keep the project moving”

0celo7

@EmilioPisanty Unless you push your git every 15 minutes I don't see the difference.

John Rennie

@EmilioPisanty you say that with great authority, but in 40 years of using computers I have found a daily backup to be fine.

0celo7

And if you push your git every 15 minutes, that's annoying as hell.

vzn

15:45

@EmilioPisanty conceding myself. hypersters never concede :P

Emilio Pisanty

@0celo7 there's a difference between commit and push

@vzn OK. That's not what you said, though.

Semiclassical

And that does create certain incentives for how such projects get presented/sold as

vzn

@EmilioPisanty I do concede. theres this thing in english called "implied subj" etc

0celo7

@JohnRennie Ok, how about this: is it possible to set up Windows to clone a folder every 30 minutes and save the clone?

And just do this indefinitely?

That would certainly appease Emilio.

vzn

@Semiclassical think you have it very exactly. might dig up some links on this if there is interest just ran across one by martinis et al nature

Emilio Pisanty

15:48

@vzn not particularly, no. Spanish uses implied subjects. English doesn't really, and if you think that that's what you're doing all the times you ommit the I, then that's not standard grammar. It makes your text extremely hard to read.

@0celo7 you miss out on the commit messages

I'm not saying you have to do it

0celo7

I never write those.

vzn

@EmilioPisanty its a chat room. maybe you have better grammar/ usage than avg. trying to increase stds in here seems like (at times) trying to boil the ocean to me.

@ACuriousMind would you please take a look at this profile picture?

Emilio Pisanty

@ACuriousMind moot, as wasn't an imperative clause

John Rennie

@0celo7 Windows has a technology called shadow copy, which effectively snapshots the state of the disk at the time of your choice. Then you can go back and retrieve a file from any of the shadow copies. That's what I would use if you want regular backups throughout the day.

@vzn if you wrote clearly and correctly people wouldn't have issues understanding you

@0celo7 It doesn't literally copy all 400GB. What it does is take an initial image then journal any changes made to the disk. You can get back any previous state of the dist by replaying the journal up to the point you want. So the impact on disk space is minimal.

@0celo7 it might be more accurate to describe it as - the time one saves on tying isn't "saved", it's just imposed on others' reading.

@user685252 maybe that comes from this kinda thing?
