  • It wasn’t about George Floyd as an individual. It was about what that case represented. People weren’t rioting to get him back alive, they were angry at the system which caused his death among many others. Police killing black people is a thing that keeps happening over and over again in the US. It’s a systemic issue that is never fixed. Floyd just ended up being the face of a movement born out of a lot of frustration about police brutality in general, possibly because of the way that situation was filmed. If he hadn’t died, then some other case would’ve served as the catalyst for the same movement.

    Oh and the exact manner of death was quite irrelevant. Either he suffocated due to having a boot on his neck, or then he OD’d and the officer killed him by omission, failing to provide medical attention. Most likely it was a bit of both.



  • Hydrostatic equilibrium yes, but equal? No. We agree that centrifugal force is a factor. Now ask yourself, why would gravity suddenly strengthen at the equator to get the surface acceleration to stay equal to that of the poles?

    It doesn’t. As a result the Earth seeks a new hydrostatic equilibrium, bulging out at the equator. This in turn strengthens the centrifugal force a bit while also slightly diminishing the force of gravity (because more of the planet’s mass is farther away). So the same effect is taken even further. Local differences add a layer of noise on top of this, but the end result is that the net surface acceleration is measured to average slightly less at equatorial regions than at the poles, with for example Singapore getting 9.7639 m/s2 of downward acceleration, while Helsinki gets 9.825 m/s2.






  • I think you’re taking the trollface in the meme a bit too literally. It’s annoying and unnecessary, and can cause mistakes that wouldn’t have been possible otherwise. Ahem, the Mars Climate Orbiter is a good example of a particularly costly one.

    Nobody is flying into an incoherent rage. It’s merely annoying having to accommodate the outdated quirks of one country. You having to do the opposite is quite reasonable on the other hand, because you’re not accommodating the conventions of one country, but those of the rest of the world.





  • Bear in mind that there are multiple countries where English is the largest language and metric is used, and that English is the modern lingua franca. It just so happens that the largest english speaking country has some weird ways to measure things. As such those weird measurements and associated conversions are often forced on anyone who wants to look for a recipe in English, be that their native language or not.



  • Oh no. I just want to be rid of the imperial system. I would have no issue with it if it wasn’t a part of my life. Unfortunately I work in a field where imperial units are used world wide (apart from China and Russia for historical reasons). Because of this, I use some of those units myself every day at work. I understand some of them but take no pride in it. The only reason that the imperial system is still used so much is purely by convention. It is inferior to the metric system in every aspect. I do not feel superior to people who use imperial units because as stated above, I am one of them. People who I feel superior to are the ones who delude themselves into thinking that this somehow isn’t purely because of convention. I dislike them because they are forced upon me by international conventions. OP appears to dislike them because recipes written in English force those units into their life.






  • #1: I doubt there would ever be a situation where those same resources wouldn’t be better used to make things slightly less unbearable on the home world. In our case, even if we covered the world in poison and had an endless nuclear winter, Mars would still look like the worse planet to live on. It’s doubtful whether or not a better one exists within any “practical” distance. If the aliens happened to have a lucky spawn in a star system with multiple habitable planets, good for them. They have another chance to figure things out. But interstellar flight (not to mention colonization) is still vastly more difficult.

    #2: Exploiting the resources of the solar system is orders and orders of magnitude simpler than establishing self-sufficient colonies in uninhabitable space or planets. The show For All Mankind threw out most of any believability it had a while ago, but even there the entire fourth season revolved around the subject of how even a single asteroid full of rare earth metals would sate our hunger for such a long time as to effectively kill any initiatives to expand in space.
