  • Sad to see people trying to correct you here, maybe I can help explain.

    Gravitational force between two objects is GMmr^2, for dropping objects on the Earth (or Moon) we ignore the mass of the object we’re dropping because it’s practically insignificant, but if your experiment really was perfectly accurate then the observed rate would be extremely slightly different as the heavier of the two objects being dropped is also pulling the Earth up towards it a bit more than the lighter object. If the person performing the experiment is standing on the Earth (or just using the Earth as their reference frame) they would see this as the heavier object falling faster.


  • You’re right that light is not “a wave and a particle depending on whether you observe it”. Instead, light is a quantized field. It is a field because it exists at every point and allows for wave-like behavior such as superposition and interference (both things seen in all fields, like waves in water or radio, etc.). But it is quantized because when the field interacts it does so via photons which can only exist in integer quantities. This quantization of interaction of the underlying continuous field gives us all the “weirdness” we see. Okay, not quite all of it, there are still even weirder parts of quantum mechanics, but it does explain the double slit experiment.







  • Yup, because that’s how adjectives work

    The real complaint is people who refer to women as “females” which makes them sound like ferengi. Saying a “female engineer” is just correct grammar. Some folks have instead, lacking a capacity for nuance (and language) taken this to mean that there is an issue with the word “female” in general.




  • I read it originally from a poster on a privacy/security reddit who was reporting their personal experiences. It isn’t the most reliable source but in this context I consider it worth accounting for anyway, as what the person described experiencing is both possible and plausible. For anyone who is serious about preventing these sort of privacy breaches, the open wifi vector should absolutely be considered and guarded against if possible (easy but less comprehensive approach would be to see if there is an airplane mode on TV, harder but more reliable is to physically disable or shield the wifi module on the TV itself).



  • How does that logically follow? It seems obvious to me that if every choice is going to piss people off then you simply disregard that as a factor and then make the best choice possible. If that had been their decision process and status quo was the best choice on the merits then that would be perfectly reasonable. That was not, however, the process they described in their blog, instead they remained entirely focused on the one issue that they should have ignored.
