A Paper Posted Last Month Claims To Have Achieved Superconductivity at Room Temperature, But Other Physicists Say the Data May Be Incorrect (vice.com)
dmoberhaus writes: Last month, two Indian physicists posted a paper to arxiv claiming to have demonstrated superconductivity at room temperature. If this paper is legitimate, it would represent a breakthrough in a problem that has existed for superconductivity for 100 years. Understandably, the paper shook the physics world, but when researchers started digging into the data they noticed something wasn't quite right -- the noise patterns in two independent measurements exactly correlated, which is basically impossible in a random system. The Indian researchers have doubled down on their data, and things only got weirder from there. This is a look inside what could be the biggest drama to happen in physics in nearly a decade.
The researchers either jumped the gun or faked the results.

hate to be told they're wrong
I seem to remember several years ago researchers in Fairbanks, Alaska had already achieved room temperature superconductivity. The trick was to turn of central heating as I recall...

Is Vice really a valid source for news like this?
Evidence secured!
If only there was some kind of something-something method by which one scientist could reproduce another scientist's results. Theories could be formed. More experiments tried and reproduced. Etc. Such a thing could be a force that would propel technological advancement forward at an incredible rate.
If someone can invent some kind of scientific method, they should patent it!
I'll see your senator, and I'll raise you two judges.
The researcher who found the unexpected correlation was being overly generous by suggesting it could be evidence of a not-yet-understood process. The green and blue dots from separate test runs match up essentially pixel for pixel. I'm not going to speculate whether it was an innocent error or something worse, but it's clearly not a natural phenomenon.
They did achieve superconductivity at room temperature....it is just that the room was on the surface of Neptune
Just count the many "proofs" of the Riemann hypothesis.
So they ran the same experiment twice, and got almost identical noise? I don't have to pull any punches here because I'm not publishing a critique.. but that just strikes me as high evidence of fraud.
Entirely speculation here, but I'd guess they ran this experiment once, got the result they wanted, and were incredibly excited. Nobel Prize Time! Then they ran it again, and again, and again.. couldn't replicate the results, but still wanted to publish. So they faked the second set of data, and hoped nobody would notice.
Still it _could_ be something weird... Honestly I hope it is. But realistically this is just fraud, or at best some terrible experimental error.
Putting aside whether it's real, TFP claims superconductivity occurs at 236K = ~35 below zero in whichever temperature scale suits your fancy.
That's a bit nippy for my taste.
While we all want someone to find this, as it would truly revolutionize lots of things ... I fear the only 'superconductor' these guys will be seeing will be on the train ride home.
So something which is random correlated exactly on a graph? That sounds pretty much impossible to me.
Which positively screams some form of bullshit going on there if someone is going to the trouble to do this.
Identical noise measurements, shady accounts pretending to be someone else asking people to not criticize the paper ... that sets off alarm bells about this for sure.
Let's say I'm skeptical of this for the time being. It would be cool, but if TFA is accurate, there's some very questionable stuff happening around this duo.
Turns out they moved on to "science".
Yes.

There are many other problems with the paper. They're claiming it's done using silver and gold, for instance, neither of which have shown any evidence of superconducting at all. It's possible that if you mix them up in the right combination they somehow start superconducting, but it's a really extraordinary claim to add to the room temperature (okay, -35F) superconducting claim.
Luckily this one should be pretty easy to replicate assuming they're forthcoming about the procedures. If it's not fake they'll be happy to tell everyone the process. If it's fake, they won't be.
If he DVRs it, why would he care about commercial breaks?
He specifically records the commercials so he can understand Republicanism better. Turns out it's also all about jingles to entice spoiled children to waste their money and/or vote. Hence the matching clown mascots.
Lots of things correlate. What was the underlying mechanism?
Anyone calling this the biggest drama in physics in a decade is being rather ridiculous. It may be an /example/ of a controversy (likely about faking data), and thus an /example/---one of many---of bad-actors in science.
However, there have been much bigger events (Opera's faster-than-light signals; LIGO's observations of gravitational waves; continual explorations, theoretical and experimental, of inflation; and so on) going on.
What's all the controversy about? I've had room-temperature superconducting technology for decades already, why are the rest of you so far behind?

Yes, Trump is now staffing up the Dunning-Kruger Effect Institute of Science and Technology. There first task will be to recreate the Fleischmann-Pons experiment!

1. a portion (and unlike the claim, just a segment of the data/graph) of two separate runs have identical noise, not impossible but improbably (depending on a couple of things, including length of segment as well as resolution of the measurement). 2.Authors refuse to supply any of their material to others, not surprizing in industry, but deeply frowned on in academia. 3. Authors refuse to clarify their methods which are (in the view of other experts) insufficient to allow reproduction of the experiment. So, it isn't open and shut case of fraud, but extraordinary claims require extraordinary evidence, and this - so far- fails that test.
While it wouldn't surprise me if the data was falsified (extraordinary claims requires extraordinary evidence), here's one possible explanation for those who wish to cling to a glimmer of hope.
The problem is that the blue and green show the same values, corresponding to 0.1T and 1T, only shifted by a constant small amount in the noise region. But suppose the two susceptibility values were measured as follows: change the temperature to a new value, let things sit a while to be stabilized, then do the 0.1T and 1T measurements quickly.
While the temperature is stabilizing, the material may be undergoing some small random but slow changes in stress and strain, shifting the "background noise" a little at each new temperature. If the 0.1T and 1T measurements are made in rapid succession, they might have the same "background noise" values since there wasn't enough time for it to change. The constant shift between blue and green might be a systematic shift related to the intensity of the magnetic fields involved.
Anyone that says otherwise is a rich old entitled white person. We must not let white culture be the be arbitrator of reality. If an Indian scientist or an African American scientist or a Chinese scientist says they have found a way to transmute lead into gold using etheric energy, who am I to say he is wrong. I must not allow white scientific imperialism stomp on the scientific acievments of other races that are more valid and worthy than those put out by the Europeans.
You realize you're just like all of the other trolls. Not even original. You're a conformist cunt. Cant even survive on imgur, had to come to slashdot. I bet you love to look at yourself in the mirror and cry, it isn't fun when the shelter falls down is it.
I have worked with enough Indians to know that they are incapable of saying "hey I might be wrong." If you talk to just about any Indian, you'll hear that India is the best place on Earth and that Indian shit doesn't stink. It's impossible for Indians to be wrong because everything Indian is the best in the whole world.

...but it really shows that you got modded insightful, instead of funny.
I realize the sarcasm, but I truly wonder if the ones that modded you up did.
Anyone should realize the odds of recording the same noise data is essentially nil; on the order of magnitude of the odds of all the air bunching up in one corner of the room suddenly.
On the same subject, I had an intern work with our group for 6 months; his first task was to measure a set of photopeaks from a scintillator detector.
He presented an amazing analysis of 12-bit sampled white noise I've ever seen. (He did not turn on the 'high voltage' to the PMT, as he thought that was "dangerous".)
But the analysis proved it was truly random, within it's limits, lol.

Even the debunking was explained to you by someone else, right? :rofl:

If the claim had been based on factual data, it would have been headline news within days. I'd love for this to be true, but I'm not going to hold my breath. My money's on never hearing another word about this again.

There is no magical "something-something" method, unfortunately. It is a literary image, not a real thing. In reality, the person from the TFA has published an abstract description that contains no recipe for verification. So, anyone who wants to try and replicate the result will have to come up with their own "thing", and nobody will know if it is a replication, what errors were made, and so on.
The so-called "something-something" method is a hodgepodge of hand waiving, improvisation and luck, much like it was when the people who performed it were alchemists, and not "scientists".
Nobody that mattered, that is. It is not possible for third-world non-people to achieve this kind of result. Only European science can. It is proven.
Maybe they found the elusive cold fusion that people have searching for instead...

No, he's actually a very good troll. Do you know how we know?
Lower the temperature of the room enough and superconduction will 'just happen'.
Reminds me of a movie a vampire movie long time ago; someone with bite marks on their neck, drained of blood. Detective asks the Coroner how did he die? Natural Causes. Natural Causes? Yeah, naturally, if you don't have any blood in your system, you die.
Anyone with a college degree is expected to not just pick any source, but strong sources that readers will likely to believe.
Ummm, sources that "readers will likely believe" routinely does not correlate positively with "strong sources". People will tend to believe whatever made of nonsense most strongly correlates with their pre-existing biases and beliefs.
Eventually, when enough people are convinced, your hypothesis is essentially voted into being a theory.
Science is NOT about convincing people. Science is a process of establishing models that are have predictive power regardless of whether people believe them or not. Eventually people tend to come to a consensus behind models with proven and confirmed predictive power but this is a second order effect and not the actual point of the process. Science is what is true whether or not you believe in it. This is why when people use the argument about scientific consensus in regards to climate change they are making the wrong argument. It doesn't matter what the scientific consensus is - it only matters whether the models have predictive power. Consensus is just opinion and opinions can be wrong - even informed opinions. The argument they should make is that the climate models correctly predict XYZ and we have lots of various models all getting the same results.
When truth-establishing processes are dictatorial in nature, you get crazy religious wars.
True but group-think can be rather dictatorial in effect. Nobody forces people to believe in certain crazy ideas (like religion) but if you get enough of them collectively to believe it then it becomes an unquestioned dogma.
"This is a look inside what could be the biggest drama to happen in physics in nearly a decade"
Who writes these news, Indians?
What about the claim of neutrinos moving faster than light, which was less than 10 years ago? By far bigger drama than claiming room temperature superconductivity.
Who would have thunk it? Hydrogen, a highly combustible element, and Oxygen, which will itself freely burn, combine to together form WATER... Not POSSIBLE say physicists!
That's a demon, wearing a human suit.
You can tell by the lies, it easy.

You know, it bugs me when people say "well science is not a democracy. Something is either proven or it isn't."
The scientific method is essentially democratic
You didn't get what "the people" say there.
Mainly because you have wrong ideas about science and/or democracy.
Science is not a democracy because you don't get to DECIDE or COMPROMISE or AGREE on the nature of reality - reality just is.
You can't argue or vote your or any other way with science any more than you can make a cold fire by coming up with an alternative temperature scale.
And there's nothing "essentially democratic" about the scientific method itself. It is in fact an autocracy of reality.
There's ONE way to do it right, you don't get to choose another way, it doesn't matter how many votes of how many people you got on your side - reality just puts its foot down and goes "It's MY way or it's not science. Deal with it."
One person claims to have done something via an experiment, and that doesn't prove anything. You need a whole bunch more people to do the same experiment....to convince them.
No.
You are confusing some kind of a mix of publishing and academia and education and general knowledge with science.
One person's experimental proof of a theory, if done according to strict rules of scientific method, is enough.
For the precise reason that it would provide the same exact results REGARDLESS of how many people do the same experiment or how many people are convinced.
Also, replication or peer review are NOT done in order to convince "a bunch of people".
Replication and peer review are done in order to try to TEST the theory and/or the experiment - by doing the exact same thing as the original experimenter.
To see if it will break this time. And if the science behind the theory and the experiment is solid - it won't break.
REGARDLESS of how convinced a "bunch of people" are.
If scientific method was about democracy and conviction, everyone could simply agree that the Moon is made out of cheese.
And then the conviction that the Moon is made out of cheese would make it so.
You just gouda believe it hard enough, that's all.

The data is faked, this is not a story. :facepalm:
Lots of claims, no reproducible results.
DUH!!!
Make room temperature nearly absolute zero Kelvin, and you have the answer!
