    I disagree there - peer review as a system isn’t designed to catch fraud at all, it’s designed to ensure that studies that get published meet a minimum standard for competence. Reviewers aren’t asked to look for fake data, and in most cases aren’t trained to spot it either.

    Whether we need to create a new system that is designed to catch fraud prior to publication is a whole different question.



  • Well, yes and no.

    Quantum computers will likely never beat classical computing on classical algorithms, for exactly the reasons you stated, classical just has too much of a head start.

    But there are certain problems with quantum algorithms that are exponentially faster than the classical algorithms. Quantum computers will be better on those problems very quickly, but we are still working on building reliable QCs. Also, we currently don’t know very many quantum algorithms with that degree of speedup, so as others have said there isn’t many use cases for QCs yet.







  • In my time looking for published papers, I have only very rarely seen papers which are also hosted by the university of the author. I suspect in your case it was hosted because of something specific to the school or the author, rather than a general thing.

    What I am seeing more often in my field is people posting a version of the paper on “arxiv”. This is a similar open-access approach, but you do have to be careful with arxiv papers as you can post anything on it, including work that never was or will be peer-reviewed.



  • You seem to misunderstand how the penalties work out. 95% of the time after a fight happens, both teams get offsetting penalties, and so neither team is at a disadvantage because of the fight alone. There are instances where one team ends up with more penalties after a fight, but it’s usually because of something that happened before the fight and prompted the fight (and should’ve been a penalty anyway)


  • If you’re mixing things up in the kitchen, typically you try to be somewhat precise with ratios.

    The difference in this case being that because the actual ratio of the blend is unknown, you don’t actually know how it would crystallize. Technically they could even change up the ratio week to week based on the price of high-fructose corn syrup so you wouldn’t even get consistency from it.




  • Believe it or not, but companies outside of Boeing and Airbus are capable of designing airplanes.

    It’s not just “good” regulation holding them back either - in 2017 Boeing accused Bombardier of “dumping” some CSeries planes because they sold them to Delta at below the retail cost (about a 30% discount). The CSeries was/is a good plane, but took an incredibly long time to get through certification so Bombardier had been losing money and was desperate to sell them. Boeing complained about this discount to the US International Trade Commission who imposed a massive fine on Bombardier. Because of the delays, Bombardier couldn’t afford to fight the fine so they ended up having to give up a 50% stake in the design to Airbus for only $1. The year after, the fines were appealed and overturned, but the damage was already done. Bombardier has since completely sold their stake in the CSeries (one less competitor), and Airbus gets the renamed A220 series for a massive discount.

    As an aside, I can’t argue that the FAA doesn’t do more good than harm in this space generally, but I’m the last ~5 years it’s becoming clear to me that they have a massive blindspot for Boeing in particular.
