/sci/ - Science & Math

It's legit. The extra energy comes from lattice vibrations in the surrounding medium. No laws are being broken.

First general relativity, and now thermodynamic is wrong!?
We really know nothing, G-d is our light in the dark.

>>4457960
This. It's at very low power, and it's harvesting thermal energy and emitting it as photons.

>>4457981

The neutrino thing was special relativity you moron. Not to mention it turned out to be a mistake anyway.

>>4457990
Not him, but really? Wasn't it carefully measured beforehand?

>>4457994

There was a loose fiber optic cable in the timing circut, causing the clock to be a few nanoseconds off.

>>4457994
They tried to be careful. They still had weird results. They appealed to the community for help in checking WTF was going on. It now seems that there were multiple errors with the experiment, and more experiments are being done to recheck that it was in fact a result of those errors.

IIRC they technically never published in a journal, and certainly never went around crowing about "relativity being wrong". That was all the bullshit popsci media that try to make things interesting.

>>4458002
Is it confirmed to be the culprit yet?

>>4457955
It is not possible.
Nothing can be more than 100% efficient.

They are not taking into account the heat energy in the calculation.
If it transmitted 100% of the electrical energy into light, and 100% of the heat energy into light, then it would be 100% efficient.

It does not.

>>4457986
Very low power being that you wouldn't even see the light emitted from the LED unless you had special detection equipment like MIT does.

For reference, most LEDs operate in mW. This is a pW LED. I do wonder how large these devices are. I would guess an area below 1 um^2.

>>4458013
I love how you didn't even read the article, and pretend you know what they are actually claiming.

>However, while MIT's diode puts out more than twice as much energy in photons as it's fed in electrons, it doesn't violate the conservation of energy because it appears to draw in heat energy from its surroundings instead. When it gets more than 100 percent electrically-efficient, it begins to cool down, stealing energy from its environment to convert into more photons.

Choke on billions and billions of cocks.

>>4458021
I did read the article (the start of it anyway)
And as I said, they did not take the heat energy into accont during the calculation.
Their (incorrect) calculation for efficiency is:
E = [light energy out] / [electrical energy in]
which gives over 100% because they forgot to include heat in the denominator.

>>4458012
The other experiments haven't been completed yet, IIRC. It'll be a while.

>>4458038
There's more than one efficiency, because you pick what input and output energy types you're measuring.

Only the total input and output need to obey conservation. The electrical input vs. the optical output is over-unity. Deal with it.

You're right, but you're being such an aspie that you can't see that *they're not wrong either*.

>>4458038

>because they forgot to include heat in the denominator.

You really think they forgot? They omitted it because they're talking about electrical efficiency, not overall efficiency.

>>4458050
I know they are not wrong, but only because they qualified their '230%' answer with an explanation to show how it is not the 'true efficiency' and the laws of thermodynamics are not, in fact, broken.

Good. I just hope you're not suffering under the delusion of having contributed something useful to this thread.

It's the nature of popsci media source to spice shit up, and I hate it too. But I hope we agree that the original authors had no need of your correction.

http://prl.aps.org/abstract/PRL/v108/i9/e097403
>A heated semiconductor light-emitting diode at low forward bias voltage V<kBT/q is shown to use electrical work to pump heat from the lattice to the photon field.

>>4458038
>>4458056
>I didn't read the entire article
>Tried to correct something they already talked out

God women are dumb, out.

>Using heat energy in an electrical device

Fuck entropy.

>>4458202

Entropy still increases. The photons being emitted have higher entropy than the heat that was absorbed.

If you read the rest of the article, you'll have your answer. The author just used that as an attention getter. Fucking /lit/ fags think they could say anything.

so if this shit converts heat into light, couldn't they put a shit ton of LEDs inside computer processors to absorb and dissipate the heat as light instead of using XBOXHUEG heatsinks? Sounds like future computers are going to be glowing black boxes.

>>4458225
It's still is an interesting topic, because they have essentially created a solid state heat pump.

>>4458238
>shit ton

I think you already know why this will fail.

go away EK and stop mocking your alternate personalities

>>4458275

I got banned for posting as you ;_;

idk but I got banned permanently for ban evasion.

>the name you were posting with was anonymous
you wernt posting as me, and my old trip wasnt banned (at least not permanently, and i never evaded bans with that trip)

w/e, you dont need to use the trip anyway, everyone already knows hat the EKFnQ trip was revealed, so its the same as anon now anyway.

>>4458318
this happened to me about 5 times after you gave up your trip too. ;_; >-<

Stop impersonating me.

Can you be my gf, EK?
Please respond.

;_;

>>4458339
Are you and harriet still together?

>>4458342
nah, sorry hun.

>>4458318
so hows life, in LA, champ?
heheheheh

>>4458377
define 'together'
yes, we still live together, but if you're implying we were ever 'together' as in, romantically attached, then no, we never were.
also, she's straight.

>>4458382
Fucking knew it.

EK is Laurelai.

there are two people on 4chan. One is an emeritus professor at UCLA. The other is you. Hi.

Check out reddit.com/r/spaceporn . Shit was so cash

>>4458449
pretty hard and loose with the word 'prove' seeing as im definitely not that poster (i only ever used the FnQ trip, and now i dont use any trip- so no.)

CONFIRMED FOR FAKE EK

Real EK used a trip before FnQ. That trip was broken and/or leaked, and consequently she started using another.

Holy fuck. You were never EK. Confirmed for scottish neckbeard impersonation after real EK left. Fuck you.

>>4458455
holy shit, there's a fucking gay board and I didn't even realise it.

That explains the total absence of gay threads from /b/.

>>4458458
oh yeh, #taxon.
sorry i forgot, but yeh, that was mine as well.
(even if you think #taxon isnt me, fuck you, because i've posted FAR MORE as FnQ than i have as #taxon anyway.)

>>4458463
It also explains why we have so few engineer thraeds on /sci/ now.

>>4458463
how is /hm/ a gay board?
theres probably far more hetro fems there than their are gay guys.

>>4458467
Dude, just give up.

When you explicitly make massive errors that nobody who knows EK, including EK, would make, you show yourself up. It's clear now exactly what you did.

>>4458474

>>4458474
We need a hetero board. This weird minority is spamming all over our gay 4chan.

>>4458476
i havent used #taxon in years, its fair enough if i forget.
and anyway, im posting as anon now, so theres no guarantee im ANY EK at all.
lol, it doesnt even matter, STFU
(but FYI, yes i am the real EK, and always was)

>>4458480

Does occasionally fapping to trap porn make you gay?

>>4458480
how can their be a hetero board?
/s/ for bi's, lesbians, and straight males
/hm/ for bi's, engineers, and straight females

>>4458490
No, it makes you hetero, which is even worse.

Yes. Only faggots fap to it just occasionally.

>>4458490
dunno, how are you imagining it?
if you see it as taking 'her' cock, then yeh, it makes you gay.
if you imagine fucking 'her' and imagining 'her' as feminine then it probably makes you more straight....altho she does have a cock, so its still kinda gay.

Depends.

Without going off the "hurr gender is an illusion perpetuated by jesus" deep end, the whole gay/straight/bi thing is basically a human invention. There is no term, currently, for those sexually attracted to transgender people and the opposite biological sex.

We have homolust threads all the time, hate females and love traps. If that's not gay, I don't know what is.
