@ACuriousMind There were historical episodes, too. I seem to recall that in the US the Hurst operated newspapers duked it out with a couple of other big chains for mind-space in the early 20th century., in a way that people would recognize from Fox-vs-MSNBC today.

Err ... Hearst. I have a student with the other spelling and it has infected my brain. Or something.

AngusTheMan

@dmckee and @alarge Thanks guys! I am trying to modify the way I explore my configuration space with unequal steps at different temperatures. At the minute I just have smaller steps at lower temperatures for localised sampling. Both are subject to barrier functions that automatically reject updates if they exceed the pre-determined limits. If I instead use penalty functions I am hoping for a quicker convergence? Is that a valid plan you think? :)

dmckee

@AngusTheMan I've no idea how it will affect convergence, but I'd guess it will improve your odds of finding local extrema along the boundary. Possible the right place to ask about that is Computational Science. Better chance of finding someone who has experience with it.

alarge

17:18

@AngusTheMan Before starting with penalty functions: how did you select your step sizes, and how many moves get rejected? Are the rejections close to the rule of thumb of a half or so?

AngusTheMan

17:37

@alarge At the minute I have ... variable=variable_old+random_number*step_in_variable ... then a check to see if variable is within limits pre-determined. If it lies outside the acceptable limits it is rejected. At lower temperatures I have just divided step by 10. Primitive I know but, it works quite well. The accepted-rejected is really 50-50.

However I am thinking of dispensing with that method for something a little fancier. I am not doing this for any computational comparison experiment, literally just to see if it gets me to the answer any quicker. My focus is getting results, not so much the method etc

alarge

@AngusTheMan Why do you think a soft constraint would help convergence? Are you stuck near the boundary? I'm not sure what exactly are the quantities of interest anyway.

AngusTheMan

@alarge

@alarge I think what it is, is I am just tinkering with new ideas and hoping that by some miracle I won't have to do nested MPI to increase the efficiency/ decrease CPU time .

alarge

@AngusTheMan Well as I mentioned earlier, do make sure that you are using SIMD (likely AVX) and in general try playing around with the compilation of the program. Can get you significant gains.

AngusTheMan

@alarge I am investigating that! Thank you a lot for your help :) I'll let you know how it goes!

@AngusTheMan Also, did you profile your code? Do you know where the bottlenecks are? With MPI and all your computations might be memory bound.

A: Resistance of a diode

Recombination of electrons and holes doesn't really dissipate heat. Keep in mind that "holes" are really a handy abstraction for thinking about semiconductors. They don't really exist as physical entities other than a place where a electron could be but isn't. Electrons aren't completely free ...

0celo7

@Slereah Any tips on what quests to do

Respawned Fluff

I think at the very least he is ignoring phonons, although he is right about no heat, but because of the generation/recombination equilibrium. I'm no quantum physicist though, and he is the EE top-scoring user.

@Qmechanic: Another question on a situation where I'm not sure what to do: A user *repeatedly* gives bad answers to questions. They technically answer it, but they offer - in my eyes and, judging by the downvotes, that of others - no insight into the underlying physics. They are frequently just pictures with one sentence or formulae without explanation. When commented on, the user will insist the answer "is correct" and that further exposition is unnecessary.
When not commented on, the user will neverthelss post a comment that says the downvotes are "there to discredit him" and the answer i…

dmckee

@ACuriousMind I think you should ask another mod, because I've been around the block a couple of time with that guy and may not be a neutral arbiter.

ACuriousMind

@dmckee I see.

dmckee

For myself I have simple stopped interacting with him.

And I'm trying to lead a little by example.

ACuriousMind

Well, I've already resolved not to comment on those posts anymore, I mainly wonder whether flagging the comments about "discrediting downvotes" as not constructive is, well, constructive.

Slereah

18:38

@ACuriousMind I wonder who this user could be!

ACuriousMind

@Slereah Probably not who you think :P

AngusTheMan

@alarge I have profiled the Monte Carlo moves and found that at at lower temperatures I had inefficient Markov chains because the acceptance ratio between parallel chains was variable. I have fixed this by controlling the acceptance ratio between adjacent chains. So now everything is as efficient (or inefficient) as each everything else.

alarge

@AngusTheMan Cool. What I had in mind though was making sure that you know where exactly in the code most time is spent. Which loops etc.

Slereah

Pretty accurate

AngusTheMan

@alarge Oh I see, yes I have an outer for-loop that contains within it the Monte Carlo (which has been MPI'd). It is the computation of the outer loop which takes the most time. I don't know if it is memory or cpu bound .. I would guess cpu?

ACuriousMind

@0celo7 Hm, I became unsure whether the "I have" is as understood there in English as it would be in German.

0celo7

@ACuriousMind Oh, you can put that there

But one commonly drops it in informal speech

ACuriousMind

@0celo7 That's what she said.

@0celo7 That was exactly what I was unsure about.

AngusTheMan

Wait are you saying you would use "I have" more than "I've" @0celo7 in informal speech?

ACuriousMind

@AngusTheMan You have to differentiate between have as a full and an auxiliary verb

The full version is usually not contracted.

Qmechanic

HDE 226868

@dmckee Uh . . . I guess. I was going to ask if there's any physical significance to the break in a double power law.

dmckee

@HDE226868 It usually implies that you've entered a regime where new physics sets in or that two effects have traded sizes so that a previously small one now dominates over a previous large one.

@dmckee STDs are bad

JokelaTurbine

This might (or might not) reveal us more than any new test made in Particle accelerators

Slereah

G is pretty poorly known compared to other constants

Then again, I'm not sure it's that important

JokelaTurbine

@Slereah If constant is constant or not constant is important.

dmckee

@0celo7 They taught that in the bad old days, too. With similar modest level of improvement in STD rates. Something about being young, I think. Even vaguely recall.

HDE 226868

19:42

@JokelaTurbine Out of curiosity, what makes you think that would produce different results than anywhere else?

dmckee

@JokelaTurbine Observations of the solar system demonstrate that it is constant over scale up to tens of AU. Observations of multiple star systems don't give as much precision but are also consistent with constancy over hundreds of light years or more (compare HR-diagram mass with orbital period...).

yuggib

@0celo7 treponema pallidum pallidum is fun

JokelaTurbine

@dmckee Thanks, but after studying a while these observations. They seem to be sort of circular reasoning.

dmckee

You really do need to know something about the depth and breadth of observational data before you start trying to form new theories. Take your ideals, put them in a box for later consideration and go start learning some real physics so that you have the ability to put your ideas to the test.

JokelaTurbine

@HDE226868 The gravity might be explained by QED, in this case the G wouldn't be constant.

ACuriousMind

19:46

@JokelaTurbine What? Gravity has nothing to do with QED.

yuggib

@0celo7 I had it as a plush toy...no idea where I put it however

HDE 226868

HDE 226868

Aww. . .

yuggib

19:49

@ACuriousMind Yep, did it exactly that way

ACuriousMind

@JokelaTurbine I don't follow. What has the old idea of angels pushing the planets to do with QED or a variable gravitational constant?

JokelaTurbine

@dmckee Thanks. I will try to do that. BTW, the Answer which JR gave here physics.stackexchange.com/questions/214042/… was not correct. I think you can verify this directly from JR.

@ACuriousMind I'll look you the point, short. Feynman explained how the gravity could be explained by QED, but the problem was the rotation of planets, which would stop. This explanation would change the basic idea of gravitation, and would most probably lead to a situation where the G is not constant, or, otherwice said, if G is not constant, it would be a partial hint to this direction.

yuggib

By the way, does anyone knows why JD has been suspended?

ACuriousMind

@JokelaTurbine I'm not sure what you think QED stands for. It's Quantumelectrodynamics. It doesn't describe gravity, and it can't. It describes the interaction of the electromagnetic field with matter.

yuggib

and on a related note, why has he not been suspended longer?? :-P

JokelaTurbine

19:56

@ACuriousMind feynmanlectures.caltech.edu/I_07.html#Ch7-S7

But I don't have interest to argue about any stuff. I mean our opinions doesn't really change anything in nature. Thanks. I am fine with this, and hope no one got disturbed.

my point is that we would be far more relieved if the ban had been longer

0celo7

ACuriousMind

20:06

@JokelaTurbine Are you trained in quantum field theory? Do you have an overview about the technical difficulties in quantizing gravity, and why conventional strategies fail? Do you know what the currently favoured approaches to quantum gravity are and why? If the answer to any of the above is "No.", you don't have an idea, you have something which will not withstand the slightest scrutiny by professionals.

yuggib

you talk about the devil

ACuriousMind

The time when people not formally trained in physics and/or mathematics could make contributions to fundamental theoretical research is long gone.

0celo7

@ACuriousMind Are you saying one can't self study

ACuriousMind

@0celo7 Hm, "formally trained" is not intended to mean "having completed a course", but to mean that you have mastery of the formal tools needed to do theoretical physics.

I'll take a better word for it if you have one

0celo7

@ACuriousMind I don't

@Danu There have always been autodidacts, but they have to join the community to make a real impact.

JokelaTurbine

@ACuriousMind Ok, I have no problem with that. What comes to your second comment, I propose you study history. Most of the Fundamental theories has came from not "formally" trained people, but who do have the capacity to use the needed tools and the curiosity to study the available info. Ie. James Joule was a beer brewer. What he did was simply experiments and observations. The Key to science is not really that complicated. There is nothing in world you can't study by your self.

Danu

@dmckee Can you name me a significant one in physics (so no Ramanujan >:) ) after 1900?

C'mon. Dalton!

That's a heck of an education.

@JokelaTurbine You might want to consider Danu's question about post 1900. The landscape is much more complicated than it was in the 17th--19th centuries now. And please note that I started with an assertion that autodidacts have to join the wider community to contribute.

Slereah

It's pretty hard to do experimental physics in a meaningful way by yourself nowadays

Theoretical physics is doable but there's a lot to catch up on

Okay, here's a highly non-mainstream post-1900 "physicist" who is - if nothing else - self-taught:

Kauko Armas Nieminen

Kauko Armas Nieminen (born 15 February 1929 in Kuopio, Finland) is a Finnish self-taught physicist. Although Nieminen is most known for his works in physics, he does not have any academic training or degree in physics, but is entirely self-taught. He has a bachelor's degree in law from the University of Helsinki. Nieminen's research and theories in physics are unusual. The basis of his work is the theory of "ether vortices". In principle, the theory claims that the universe is filled with ether, and as the ends of the ether come close to each other vortices appear. The center of a vortex is an...

Slereah

when was the last time a weird theory actually turned out to be true

Like something nobody thought was possible

I think it was plate tectonic

0celo7

GR is pretty crazy

@Slereah Quantum mechanics? Black holes?

Slereah

Quantum mechanics wasn't that controversial

It kinda grew naturally through experiments

HDE 226868

@Slereah It counts as weird, though.

yuggib

@0celo7 self-studying topology is easy :-P

Slereah

Plate tectonic was some fringe theory though

HDE 226868

@Slereah Oh, yeah, that sounds right. Nobody liked Wegener.

I think that was his name.

@yuggib I should just stop coming here

being around smart people is really depressing

Slereah

"His hypothesis was controversial and not widely accepted until the 1950s"

Damn

That recent?

HDE 226868

He died in 1930. That sucks.

Slereah

Then again, atomism wasn't widely accepted until like the 1910's

@HDE226868 1) why is these questions then here? physics.stackexchange.com/search?q=lift+of+wing That's the physics which Lancaster sorted out. 2) I have completed engineering studies. But I found it too simple to be noted.

@JokelaTurbine His discipline applied principles of physics.

@Slereah Hm, "$\dagger$ 1930 im Grönlandeis". Poor guy.

yuggib

a green land is a good place to die; green is a good color

Danu

@Slereah It kinda does, though.

@ACuriousMind LOL

JokelaTurbine

@Slereah If it helps, I don't try claim anything. All this stuff has been in the nature all the time. We just need to observe them. And In most of the cases the already made observations will just be lost as the stupidity growths over.

Danu

> there is no topology course

Implying I'm not taking a full-year two-part course on topology :P

@Danu I was not aware you are studying at my university now :P

Danu

I am

:P

ACuriousMind

oO

Danu

...or am I?

Who knows...

ACuriousMind

I'm pretty sure you're still in Munich

0celo7

Nothing is ever easy in these games...
