  • I agree that anecdotes aren’t worthless, but for different reasons. There’s actually a saying that goes, “the plural of anecdote isn’t data.” Anecdotes are just stories. They aren’t data points and they aren’t peer reviewed. If you want to turn anecdotes into data, you have to do the proper interviews and surveys to actually build a dataset and then get the peer review, but at that point we aren’t talking about anecdotes anymore.

    Not sure I understand. Are you agreeing that the moon landing happened but you also claim the footage is faked? Do you have any reasons to support that? You mention something about radio technology from the 1920s, but the moon landing occurred nearly 50 years later, so I hardly see how that is relevant.

    Edit: I misread your comment. Thanks to @turmacar@lemmy.world for pointing it out.


  • Yeah, I’m gonna need more than your incredulity to convince me. Like, fun that you think it is inconceivable, but your inability to imagine has no bearing on reality. Especially when there is plenty of evidence to suggest they actually filmed and broadcasted it live. For example, the fact that a live television broadcast was a primary goal of the mission, or the fact that RCA made custom TV cameras for the Apollo program , or that the broadcast lasted for hours, or any of the analyses out there that shows the video is likely real. Also, no one suggested that the Apollo astronauts had a camera crew with them - what a bizarre thing to mention.




  • You’re thinking of topological closure. We’re talking about algebraic closure; however, complex numbers are often described as the algebraic closure of the reals, not the irrationals. Also, the imaginary numbers (complex numbers with a real part of zero) are in no meaningful way isomorphic to the real numbers. Perhaps you could say their addition groups are isomorphic or that they are isomorphic as topological spaces, but that’s about it. There isn’t an isomorphism that preserves the whole structure of the reals - the imaginary numbers aren’t even closed under multiplication, for example.


  • Yeah, you’re close. You seem to be suggesting that any measurement causes the interference pattern to disappear implying that we can’t actually observe the interference pattern. I’m not sure if that’s what you truly meant, but that isn’t the case. Disclaimer: I’m not an expert - I could be mistaken.

    The particle is actually being measured in both experiments, but it’s measured twice in the second experiment. That’s because both experiments measure the particle’s position at the screen while the second one also measures if the particle passes through one of the slits. It’s the measurement at the slit that disrupts the interference pattern; however, both patterns are physically observable. Placing a detector at the slit destroys the interference pattern, and removing the detector from the slit reintroduces the interference pattern.
