First Pulsar Discovery By an @Home Project 70

pq writes "In a paper published today (abstract) in Science, astronomers are reporting the discovery of a radio pulsar in data acquired at the world's largest radio telescope and analyzed by hundreds of thousands of volunteers in 192 countries for the Einstein@Home project. This is the first scientific discovery by a distributed computing project, and specific credit is being given to Chris and Helen Colvin of Ames, Iowa, and Daniel Gebhardt of Germany." The claim that this is the first discovery to be made through distributed computing is hard to swallow; there are quite a few distributed projects out there, several of which have reported positive results, such as the discovery of the 47th known Mersenne number.

      Why would they dispute a claim that wasn't made? That'd just be silly.

      The claim was first pulsar discovery, and I doubt Folding has any reason to dispute that.

The submitter was the only one who claimed it was the first discovery, period; the actual article only claimed it was the first discovery by Einstein@Home. Please take all of that massive guilt you now have and redirect towards the usual guilty parties, timothy and any submitter of an article he publishes... sigh.

        The claim from TFMSNBCA is "The pulsar discovery, announced today on the journal Science's website, marks the first time Einstein @ Home has had a hit.". And later " The first and most famous BOINC project is SETI @ Home, which has been sifting through Arecibo data for the past 11 years, looking for signals from alien civilizations. (None has been found yet, even though more than 5 million users have been looking.)".

        No idea how you combine those two into "The claim that this is the first discovery to be made through distributed computing".

    Yes, BOINC allows people to use idle computing capacity. But if we need plenty of computing capacity today, it is not that hard to get it: It is much simpler to simply rent a few EC2 machines, or get a computing grant from Google/Y

      Is it really sad that distributed computing is so commonplace that it's resulting in discoveries in fields as disperse as biochemistry, abstract mathematics, and astronomy? That sounds like... the opposite of sad. Something went from being new and exciting but small scale to massive and available to many, and now many more projects are able to exploit it. That sounds exciting to me.

      Sure Foldit is more interesting and exciting from the technological development standpoint. Is this some kind of zero-sum game where that necessarily means it eats up the excitement points of discovering pulsars with "traditional" distributed computing projcets?

    A Mersenne number is any integer of the form 2^n - 1. If this number happens to be prime, it is called a Mersenne prime. The summary clearly means Mersenne primes, not Mersenne numbers.

      Though even his intended point I'd have to question... it's hard to call finding a Mersenne prime a real "scientific discovery". It's pretty purely mathematical, I'd think, as is any distributed algorithm that takes no input beyond the initial equations. Not that there haven't been actual discoveries - I just find the Mersenne prime search a pretty bad example.

    First off the claim in an associated release was the "first astronomical object" discovered, not first scientific discovery.

    Secondly, even that's not correct. It's the first by a distributed project with an "@" in the name. Just because a project doesn't have @home or @thegym doesn't mean it's not distributed.

    For example the PSC (Pulsar Search Collaboratory), which probably ought to be called psc@home or some such had an earlier hit.

    If they want to claim that this was the first pulsar found by a distributed project with @ in the name from Arecibo based data then they're probably correct.

    It's a cool find and a great project, don't want to come of as *completely* jaded and glad Arecibo is getting good use.

      Nothing in the abstract or the linked article makes any claims of being the first any discovery. All this is about is that this particular project had its first hit. The rest is just sensationalist nonsense from the summary writer.

    • Did some scanning ... that 'first discovery' bit seems to be conflating physorg, universetoday and other press releases. In some they say first pulsar by distributed project (technically but just barely correct), in some they say first scientific discover by einstein@home (correct) and in some they say first astronomical discovery by einstein@home (also correct).

      Somewhere along the line through sloppy editing this evolved to "first scientific discovery by a distributed project". Not a claim made by anybod

    One of the things that wasn't talked much about in the press conference was that the software heavily utilizes the GPU over the CPU when compatible hardware exists. I meant to bring it up somehow, but I was happy to be done and off camera after an hour. Media events, while interesting, require a lot of sitting still, being quiet, and not sneezing.

    Yes, the technology for doing distributed computing is now over ten years old and I was a very early adopter. So as some people pointed out that's not new 'news' anymore per say. What is computationally newer is that the projects now don't just expand at Moore's law's rate anymore and as GPUs get better it will increase much faster for the next few years until leveling off at some new growth rate. Yes I know other things have been found, but finding a pulsar was really cool. Speaking with the scientists and science media all over the world and seeing the full international scope of this project over the last few weeks was also fascinating.

  • . This is the first scientific discovery by a distributed computing project,

    Checking all the links, it doesn't look like this claim is made anywhere. The MSNBC Cosmic Log article does say "The pulsar discovery ... marks the first time Einstein @ Home has had a hit," but that's it.

  • Prior to this, I only knew of two distributed computing projects, SETI and DESCHALL. DESCHALL was an effort in the mid 90's to prove to the government that their Data Encryption Standard (DES) was not a secure encryption type, and it was successful in 1996. 14 years before this event.
