  • Most people are citizens of where they also live and give birth so this distinction doesn’t come up in most cases. But for children born to immigrants or travelers it does.

    Citizenship can either be assigned by where you were born, or who you were born to.

    Birthright citizenship, as we use the term in the US, is mostly a new world invention. In nearly all countries in the americas, any children born here are citizens without exception. No matter the parents, no matter the circumstances.

    In the old world, most countries require a parent to be a citizen in order for the child to also be a citizen.

    Generally if an american couple gives birth in Europe, the child will just be american, despite where they were born. If a European couple gives birth in any of the americas, their child will be a citizen of the americas, despite anything else












  • Sound is complicated. Its both physics and perception.

    The decibel scale is logarithmic. If you double the energy you increase the dB level by 3. Two people will be about 3 dB higher, four people would be 6, eight people would increase the level by 9 dB, sixteen would be 12 dB higher and so on.

    Some people in this thread are talking about destructive interference. That really only happens in noise canceling headphones, or situations designed to cause it. In open air, its not really an issue that comes up. I’ve never become quieter by playing an instrument with someone else. It just doesn’t work like that.

    What lets the monster hear you is the peak volume, not the minimum or average, so it will be close to the 3 dB doubling rule.

    There’s also perception. Your brain does a ton of filtering of sound information. Your brain is constantly trying to pick out the important sounds and ignore the rest. That’s why the quieter severs seem quieter when something louder happens. Also that’s why some people use white noise machines to sleep.


  • starship’s payload to orbit is zero. No matter what is promised, a rocket that can only deliver payloads destructively to the bottom of the indian ocean is not a valuable launch vehicle. There are far more cost effective ways of making artificial reefs.

    If you’ve followed elon musk’s projects you would know that the only thing he knows how to do is over-promise and under-deliver. It would be incredible if the things he’s promised happened, but none of them ever do. This starship will not be the exception.
