LED Forty Years Older Than Thought
LED lover writes "The discovery of the LED is usually credited to four US groups in 1962, but an unrecognized Russian genius got there forty years before. Oleg Losev even filed a patent on using his device for long range communications, and wrote to Einstein to ask for help with the theory — but got no reply."
I wonder how many very useful ideas like this one there is lying around right now? Probably quite a few.
According to the conspiracy people things similar to this happen all the time, with the big cooperations making sure that for example things to replace the fossil fuels does never get publicly known, I doubt there is very much truth in this, but this little story might make me think just a little more of the conspiracy theories.
If Einstein didn't react to this, I wonder how many other great discoveries that just perish because no one reacts to them?
I don't blame Einstein, I bet there was a lot of more or less intelligent nut cases who contacted him with all kinds of "great ideas" and "energy machines" all the time, had he been reacting to it all he would probably have had far less time to work on his own theories.

In soviet Russia, LED invents YOU!
Let me guess,
the first man in space was Russian as well...
It doesn't matter how old the LED gets, if you ask it it will always tell you its 40.
There is no mod option "-1: Disagree" for a reason. "Overrated" is not an acceptable substitute. Post something instead.
It's a shame so many of the greatest scientists go unrecognised or forgotten.
The real "Libtards" are the Libertarians!
LEDs are not older than we thought. LEDs were built when theory was turned into reality by those that get proper credit for those accomplishments. Sounds like the concept behind LEDs may be 40 years older, and props to Losev, but he didn't make any.
OL-LEDs, in his honour.
A feeling of having made the same mistake before: Deja Foobar
nobody gives kimchi any credit
I know those probably expired already, but any currently active patents claiming any part of that invention should be promptly invalidates. Fair is fair - nobody should be getting royalties for something they didn't invent.
I misread the title. I thought that it was saying that LEDs were the age of 'thought' + 40...
Why not patent his device, period? That way he would collect royalties out of all possible uses.
And best of all, I finally have an excuse for electronic computers in my steampunk fantasies.
How can I believe you when you tell me what I don't want to hear?
Is it the fate of those who formulated quantum mechanics to have their work subsumed by Einstein because that is the only name reporters can remember?

Am I the only one who's skeptical of this claim? It all seems just a little too perfect, especially given the original article appeared near the beginning of April...

So LEDs precede thought? No wonder people always draw light bulbs over people's heads when they get an idea.
How about the possibility he may have also invented the transistor? As mentioned in the article, I don't know what else a triode would be.

University academics, especially prominent scientists, often tend to discard letters and emails discussing or querying scientific concepts and experimental results if the communication comes from a stranger who does not have an affiliation to any recognized research organization. This is often due to lack of time or a desire not to get involved in "crackpot" theories. It can also unfortunately be due to academic snobbery.
Those of you who remember the good old cold war days will recall that the Soviets can be credited with inventing the LED, television, ramen noodles, california rolls, snow tires, the hanging curveball, and pants.
Life needs more saving throws.
What, some pre-historic LED was found that was contemporary with the non-thinking proto-humans? Oh, and how do they know when thought began? Much less that the LED was created (by what? The FSM?) 40 years earlier?
Best Slashdot Co
But did the guy actually build a LED? Because we are all good at writing a fuzzy description of how something should produce light (maybe with the help of wobbly math). Quite another feat is to actually produce the device. Oh, and patents don't matter. Anybody with time and money to burn can file one.
So, we were misLED...

Here's another Russian who was ahead of his time.
Ceci n'est pas une sig.
So he thinks - who is the greatest mind in physics? He asks his wife, Tonya -
"Olga, darling, I think I will contact EINSTEIN about my great glowing semiconductor idea!"
Olga replies, "Sure honey. He's really smart. And well connected, especially since they've been confirming his ideas left and right. sounds good to me!"
So, with great pride and hope, Losev licks the stamp on the letter and walks down the street to set it off. He holds it to his heart before he puts it in the post box, and makes a small hope that Einstein will see the beauty of his idea and help him, then with finality and hope, he puts the letter in the box.
Then he and Olga went to go boil some rats for dinner, because Russia in 1922 was a freakin' mess.

It is thought by most that transistors were the first semiconductor amplifiers (ie. device that can give gain). That is not true. Iron pyrites negative tunnel diodes were built in the 1920s http://home.earthlink.net/~lenyr/iposc.htm. Esaki got the Nobel Prize for discovering tunnelling in 1973, almost 50 years later http://en.wikipedia.org/wiki/Tunnel_diode
Engineering is the art of compromise.
Ancient greeks used a steam-powered LED technology, but it was regarded at the time as a mere toy.
You see? You see? Your stupid minds! Stupid! Stupid!
seems suspicious
I have multiple times already heard of inventions been invented twice or more independently. Does this mean that new technology gets to be invented anyway ? And that it probably depends on the rest of the state of technology and science ? And while i am at it ... if I continue to reason, this means that any invention shouldn't be patentable, because society/history has a hand in it, because the inventor couldn't invent the new tech without being raised, fed, clothed, sheltered and educated by society ? Is this what Newton meant partially by "If I have seen further it is by standing on ye shoulders of Giants"?
Yes, I'm left. You have a problem with that?
There's a brand-spanking-new Wikipedia article on him but nothing in the Russian Wikipedia for " " or " ."
This article is in Russian and is a good place to start. Here's the English translation, which comes out as "Oleg Vladimirovich losev - pioneer of the semiconductor electronics (to the century from the birthday)."
Knowledge is how to play a game, intelligence is how to win, wisdom is knowing what game to play.
"How is this modded insightful? I'll grant that this may have been true at first, but TFA goes on to say"
Because it is (marginally) insightful. In this sentence
"He probably didn't realize that the light emission from semiconductors could be useful."
He's talking about Round not Losev. ROUND, not Losev.
So when you say this
Most significantly, in 1927 Losev filed a patent for a 'light relay' that used his devices 'for fast telegraphic and telephone communication, transmission of images and other applications...'
It sounds like he found a couple applications where it could indeed be useful...
It's pretty clear you're confused. ROUND not Losev.
Now, because I'm a mean person, do yourself a favor and stop commenting. Your reading comprehension will put you in the same position as you are now, looking like a god damned retard.
In 1922 diodes were vacuum tubes with two wires in them, one of them heated and capable of emitting electrons to pass a current. What he seems to have discovered is an inverse photoelectric effect, where electrons emit light when striking a metal target.
Although, come to think of it, there were Germanium diodes at the time, so it could have been something more semiconductor-related, but the article isn't clear.

I mean to say the Russian Wikipedia has nothing under this guy's firstname-lastname or full name. To see the names, go to the English Wiki article.

Oh wait, um, that's actually what happened.

The Russians invented the light bulb first. Oh, and math. And life in general.
When we look back at history we see whole civilization who where forgotton, only to be recently re-dicsovered by archeologist finding hard tangible evidense (usually encrusted in earth). We remember the Egyptions whose whole language and writings where forgotton to history only to be rediscovered. Claims like the one in this article only lead me to beleive that no matter how well preserved information is, it will be eventually be forgotton until the distant future. I believe this erosion of history is evident in many cultures and civilizations, too many things are called into question, until the line of whats real and whats suggested seem to blur. IMHO The point.. If the evidense cannot be dug out of the dirt in 100 or 1000 years, then only whats suggested will survive. If he didn't build it, it didn't happen.

Chekov: Everybody knows the LED was invented by a little old lady in Leningrad.
I work for an R&D department in a corporation. When we see a good idea that might cut into the profits of our existing products, do we say "Okay, how can we suppress this?" Never. Such a suggestion would be the height of absurdity. A corporation that tries to fight the tide of innovation is doomed. Whatsmore, no one would want to work for it.
Rather the response is, "how can we exploit this idea to the max" and "how can improve on this idea". If we aren't allowed to exploit the idea, then we ask "how can we come up with an even better idea".
The idea of a company trying to keep a good idea down is pure fiction. I have never seen it in practise in my company. It's just not workable in practice.
How did they think it up then?
Frog blast the vent core.
Somebody in one of my college labs plugged an erasable programmable ROM (the kind with the clear window over the die for the UV erasure; who remembers those?) into its socket backwards, reversing power and ground, thereby inventing the light-emitting EPROM. Unfortunately, it turned out to be a one-time use device.
But, I wanted socialized health insurance!
Just hook them up to a little too much voltage!

They'll produce light, smoke, and maybe a few other things, as I discovered after working with them for only a short while...

This thread has made me wonder how "free" our market really is when you consider the following:
Lobbyists buying laws that help their clients reduce outside innovation and competition while weakening an individuals (DMCA).
Or how the courts can be used to hamstring competitors because the government approves vague, bullshit patents (Verizon v. Vonage is the obvious one right now, how many others have been posted here over the years?).
Oh the irony for what has become of a country born of its desire to cast off the shackles of oppressive rulers and a stifling social order. Today we the huddled masses, allow our "rulers" and social elite to conspire in ways that strip away ideals we have been indoctrinated to stand up for, but simply take for granted.
The United States has lost touch with its soul.
No sig for you!!
The more strange light. The light of future ...
I have a Ph.D. in semiconductor physics. I worked in one of the labs mentioned in the article. I have to tell you that the description in Nature is really inaccurate. What the Russian likely did is luminesce off a trap in SiC, not off the full bandgap. SiC is not even a direct-bandgap crystal. Yes, it produces blue-green light. It is a point-contact diode, but it is NOT an LED. Nothing practical or useful existed until Nick Holonyak made the first visible LED, then the first visible LED laser a few months later. Bob Hall made the first LED laser. There were a bunch of guys with Ge infrared-emitting diodes before 1962, but history forgets these guys rightly. Both the SiC and Ge diodes are such poor light emitters, that they should not be considered LEDs. Another interesting moment I believe was in the 1960s. Researchers in America claimed to have a working, continuous, non-pulsed room temperature SiC laser. It looked like beautiful blue laser light, but it was a big bust. It was not a laser. Just like this Russian, there was nothing useful going on in SiC.
High tech, complex invertions that don't obviously benefit "The Industry" can pretty predictably be expected to languish in circumstances like ours.
How many american inventors have died poor, because they were ahead of their times, while their creations are still important today?
Not to speak of scientific research, whose results ofter start to be profitable decades or even centuries after the developement of a theory.
The government has an immense hand in any system of "free market." The government creates and maintains the structure that the market operates in. The very corporation itself is an invention of the government, and such notions as limited liability, private property rights, patents, contract law, and copyrights are paper tigers without heavy-handed government enforcement. Capitalism developed right alongside, and only with persistent and generous assistance from, the modern nation-state (the Enclosure Acts come first to mind). There has never been a clear-cut division between politics and economics and there never will be, nomatter how much "free-market" rhetoric is imbibed. And now back to our regularly scheduled post of a completely different topic, already in progress.

Nerd rage is the funniest rage.
Some of you think George Bush is the stupidest person ever to be born, yet you want his government to control livelihood. Others of you think Nancy Pelosi is an utter idiot, yet you want her government to be in charge of your money
I don't care what people think about either of them - the point for many of us is that we want "none of the above" - we want someone at those levels controlling as little of our money as possible regardless of ideology, and let the market work itself out.
A supposed mismatch of great ideas and money? If there are great ideas laying around, people with money will find them and bring them to fruition. In fact they do today, it's called Angel Investors. There are plenty of small companies based around the kernels of great ideas, and some of them will go on to do rather well. And with the march of technology it has become a better time than ever before to get an idea aired and heard and possibly produced. Hell, you don't even need a company to have a company anymore, you can outsource everything but your idea!
What it's a bad time to be is a really large corp, or at least an inflexible large corp with unhappy workers.

Recent propaganda efforts have shifted focus to inventions, in order to promote Russian pride, or spread historical doubt, or who knows what they think they are doing. There's another nice video on youtube regarding their 1940s invention of gas powered running boots, kept hidden for years as a top military secret.

Too bad none of the communist theories have panned out. On the other hand the free exchange of products and services (including labor) and the private ownership of property have created huge economies that have benefited a great many people. Not theory, but practice. No system will turn out perfect results (depending on how you define "perfect"), but the free market made up of many distributed thinkers (a distributed supercomputer) can get closer to perfection than one single chairman can. ... and that is why we have LED's in almost every stinking electronic device these days. Motivation to sell something and the consumer's desire to buy something. No oppression, just blinkenlights! Oh yeah!
What you've described is a caricature of modern business, not reality.
I find modern business loaded with people with both integrity and long-term committment. Not everyone, not everywhere, but enough that the situation is no where near as dismal as you make it out.
And so far as suppressing good ideas, I state again that I've never seen it happen. I've seen good ideas ignored or under exploited, but due to ignorance or incompetence, not through evil intentions.
Businesses know that good ideas are for exploiting, not hiding. We had better innovate, better our competitors sure the hell will. The status quo is not an option.
Why retool a billion dollar operation to make a better mousetrap when you have the market, are profitable, and you could just buy the better one to put on the shelf for a rainy day. An engineer is going to be like, "hell yeah" but the thats why you will always be an engineer and not a rich bastard.

Teasing the nobles, and rightfully so!
Why is it that the Russians claim to have invented everything first. Rockets refrigerators, aircraft, computers, now transisters and LED's. But somehow they never got around to building any of them until others invented them and built them and were using them. I've even seen the claim that Russians developed steel and writing before anybody else, but it 'mysteriously' died out before the items could be exported or used.
I have to say that it looks suspiciously like they have a minor industry going in backdating proposals and papers.
Not that it really matters. Most things have several independant inventors before someone has the opportunity and ability to make it 'the next big thing'. Who gets the credit will change many times, but it won't really mean a thing. Also, there is a big difference between a proposal and an invention that produces a real product. I don't believe an invention has happened until there is a working unit.
Everybody knows 3 people with my name.

Set your phasers on "funky"!
This happens alot, with Russian inventors in particular. The commies would hide away their inventions only to see them never implemented or declassified. Then someone else in another country might discover the same thing and the original creator will get no credit for his discovery. Either that or it becomes lost to history I suppose.
So, it would seem we have been LED up the garden path...
Actually, alligators have rather smooth teeth - conical with a point. And they are relatively small, smaller per weight than the teeth of a great white shark or even your housecat. Alligators kill by drowning, not by tearing or by puncturing.
