  • My input: I’ve never searched for papers in Scihub directly. I usually find them off Google scholar or something, and then put the paywalled URL or the DOI (an identifier you can usually find in the paywalled website) in Scihub to go to that paper. I don’t think search capabilities are in scihub’s scope.





  • Can you explain this a bit better?

    I’ve seen many journals with this “open access” option (where the authors pay for open access, rather than the readers paying to read it). But the paid option never skipped the peer review process, as far as I can tell.

    I just think the last author of this paper is a big deal in his field and can do whatever



  • Maybe I am in a different environment (particularly not being American), but the old scientists still exist and are still hard at work. In fact, all scientists I know (and I work in academia) care very little for misinformation on their day to day lives. They’ll make fun of it, but don’t have any more contact with them than anyone else. They still spend most of their time working on their actual projects. The only thing that changed is that now they’re bending over backwards to include AI in their grants to make sure they’re accepted, but having to include the latest buzzwords is nothing new.

    Science communicators, on the other hand, yeah, those probably have their hands full with fixing misinformation.










  • You are being downvoted as if your point was offensive or harmful. You are wrong, but it’s totally counter intuitive and I think this is a mistake that everyone makes when studying introductory physics. This would be correct for anything moving at relatively low speeds. But when you’re talking about light, or anything that goes so fast that “percentage of the speed of light” starts being a useful unit to describe their speed, this concept starts being a bit weirder.

    This is actually the basic principle of Einstein’s theory of relativity: the speed of light (in a vacuum) is the same for all observers, regardless of their frame of reference. That means that if the laser pointer emits a laser, the light is moving away from the pointer at the speed of light. If the pointer itself is moving at a speed reeeeeally close to the speed of light… Then the laser will STILL be traveling away from the pointer at the speed of light. And if you, an observer in a frame, see the pointer moving at near the speed of light emit a laser… The laser that the laser emitted is also traveling at the speed of light from your point of view.

    And there’s no wordplay here. I don’t mean that it’s light, so of course any speed it travels at is the speed of light. I mean that if you measure its speed from any reference frame, you will get around 300000000 m/s, or around 671 million miles per hour. No matter if you are also traveling at near light speed.
