  • Your math is wrong. Kinetic energy scales linearly with mass, quadratically with speed. The graphic you included supports the idea that at same speed, the pickup truck has double the KE. The 120 mph sedan has dramatically more KE than a 30 mph pickup.

    Assuming that your sedan has exactly half the mass of the pickup, it would match a 30 mph pickup’s KE at 30*sqrt(2) mph, which is somewhere between 40 and 45 mph.

    I can’t imagine even the skinniest fit and thinnest 100% cotton denim fabric to mold to the legs enough to differentiate between toned and untoned calf muscles. I can’t even imagine the new 98% cotton, 2% elastane jeans to be that tight.

    I can only conclude OOP’s definition of toned leg definition of jeans differ significantly from mine.




  • I’m much more familiar with those terms being used in the active present tense sense than in a past tense sense. The elastic interval on the strain axis tends to be surprisingly short and plastic deformation can be difficult to detect with the naked eye.

    Holding that rubber band and having it stretch due to gravity is almost certainly an elastic deformation. I would be very surprised if there was no plastic deformation from that disposable spoon bending.

    A good rule of thumb is: if I cycled this change a bajillion times, would I eventually detect a difference? If you answer yes, then plastic deformation is occurring.





  • They can have hot breath while having a regular body temperature. Flint starters or a pilot light in their mouth combined with a high fiber diet and the right microbiome solve this problem.

    The only question left is how to move the flammable gases to the mouth. Maybe they have sacs they have to fill with roughage in their mouth. Maybe the only barrier in their digestive system is at the end so eau de colon just constantly seeps out.


  • Honestly, I just dislike other people’s dogs. They’re off leash, aggressive, and slowly bleeding into every space. Having a neighbor that encouraged anxiety and barking was an exceedingly unpleasant experience.

    That being said, I’m uncomfortable with the idea of animals being created for and existing for humans. The situation is definitely better than the livestock industry and there’s also the complication that the pets seem to be happy and humans seem to be happier with pets. It would also be exceedingly cruel to take away service dogs from those that have them.

    But, pet ownership is rising world wide. Given the demand, they’ll be bred. Pet QoL is going up. Now that they’re family, their environmental impact is going to grow.

    Yes, rescues are better than the alternative. Spaying and neutering reduce harm. I wish that the default pets would instead be cold-blooded terrestrial animals and rodents. I wish pets were unable survive outside of captivity.

    I think it’s generally immoral to own pets and that if one does, one should strive to maximize the human happiness:externality ratio. It’s a minor immorality, but the OP asked for controversial moral opinions.


  • I’m not touching the first one

    I see Big Pet has gotten to you 😔

    There’s a danger of power accumulating in any system. But there are mitigations. The greatest threat to this fantasy system are barriers to entry. If everyone has their needs met, then there can be a minimum wage of 0. With the minimum wage at 0, I think barriers to entry will drop dramatically and it’ll be that much harder to protect “your” market share.

    If we get rid of “intellectual property”, barriers to entry drop even further. Switching costs can be minimized by open standards. But then we run into the harder questions of the physical barriers to entry (rent, commodities, factories) and regulatory barriers to entry.

    With a reasonably low barrier of entry, I hope that there will be enough centers of power that are intrinsically opposed to one another so that they cannot combine and oppress us all.

    And for any government, what’s to stop them from oppressing us instead? The people always will have some mechanisms of control but every system will have its own difficulties and weaknesses. And the relationship isn’t just companies becoming governments, but there are also governments becoming companies. In fact, I’d argue it is more common for governments to become companies than vice versa. Cuba’s GAESA is in hotels, while Myanmar’s Junta and the IRGC are pretty well diversified.
