    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.


  • This isn’t a “comic book” universe, but the parahumans story universe (Worm and Ward) fits this pretty well.

    Without spoiling too much of the story, characters all get powers in response to traumatic events. The powers they get also tend to reflect the type of trauma that occurred, so if they lost an arm they might get a healing power, or if they were trapped in a burning building they might get the ability to phase through walls and a resistance to fire. All of the powers in the setting tend to follow this approach, and stay within the rules of the setting.








  • Hi Will!

    Now that you’ve tried out directing as well as acting, which side of the camera do you prefer?

    Are there any things you’ve learned from the experience of directing that you think will help in future acting roles? Additionally, is there anything you would do differently about directing Kodar if you got to start over from scratch today?




  • Gravity and vacuum are not mutually exclusive - you always have to deal with gravity forces, although they become negligible pretty quickly when you get into and then leave orbits.

    As to the specific claim, I suspect that the experiments they are currently doing (in vacuum chambers on earth) have gotten to the point that they are measuring the propulsion system producing more thrust than it’s own weight (T/W >1), which would technically be enough thrust to overcome gravity. Even if it wasn’t practically useful for actually getting to orbit, that amount of thrust on a reactionless motor would be incredible, and would totally unlock the solar system for us.


  • When you say “university staff”, do you mean professors, or some other technical support staff?

    If professors, then reaching out by email is probably a good way to start. They may get a lot of emails though, so your best chance to get a response might be timing the email right at the start of summer when they hopefully don’t have any ongoing classes.

    In terms of payment - most professors would happily talk about their areas of study with interested people for a short time (for free). If you needed a significant time investment from them though, then you might start having issues.


  • 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)
