  • I’m not sure what point you’re trying to make here. Are you suggesting that lab-grown meat wouldn’t be controlled by existing laws on what can be in food and will contain some chemical with unknown effects on the human body (outside of those in natural meat)? And that we know all about the effects of whatever contaminants or bio-accumulants may end up in natural meat? I don’t believe either of those. If we went further and listed everything that went into the animal and the culture that grew the meat, for which we would know more about the effect on the human body?

    To reiterate, I bet the lab folks could tell you the effect of their product on your body much better than ranchers and meat processing factories (or anyone else) ever could of theirs.



  • I think that mental model only works if you imagine the parabolas as reaching to infinity in a finite space so that both ends are parallel, ie having identical vertical slopes of +/- infinity. At that point, easier just to call it “half an ellipse”. To me, it’s much easier to imagine a parabola as the end of an infinitely long ellipse.

    Your intuition and the KSP example are correct though. If you imagine the plane and cone for a parabola, you wouldn’t notice any significant change to the shape (at a finite distance) if you tipped the plane ever so slightly into forming an ellipse (or a hyperbola, for that matter) since it’s all smooth changes.

    Anyway, the size of the elliptical (I think hyperbolic would have a different sort of energy state) arc that’d be formed by a thrown object would be so large relative to human scale as to basically be infinite, equivalent to a parabola. I imagine the difference might become significant once you are launching something a decent way around the Earth, but with that much energy in play I don’t think it makes much difference where exactly the projectile “lands”.
