Not that I wish anyone hurt, I do wonder if there isn't some abandonment of common sense - moving things result in accidents, there's no way to prevent that, and if you don't want to get hurt don't use them. For example, I was cycling through a large park this evening, empty because the weather was gloomy and it was a Saturday evening. Cars, cyclists, walkers and joggers use the road through the park but only myself and one other cyclist were on the long straight heading towards each other. When he was about 20 meters in front of me he suddenly fell into the grass on the side of the road. No potholes, no animals, no gust of wind, no broken parts, ... just over he went. A lapse of concentration? No idea. He climbed back on and continued. Point being that even with perfect conditions people still manage to come a cropper.
Similarly, I knew a Polish guy who couldn't speak any English after 25 years in London. He once told me "Owen is dead". I had no idea who Owen was but figured it must have been a friend of his. He must've seen by the look of sympathy on my face that I didn't understand, so he beckoned me into the kitchen and pointed at the oven - "Owen".
I think this old. That aside, if I'm not mistaken it should be expected - beyond a certain depth free divers get pushed downward, so presumably rubbish would too.
Does the term "seeding" have two meanings? I understood it to mean dropping particles into clouds to trigger rain. The article uses it to mean using particles to induce cloud formation.
It looks as though this isn't entirely the onset of an anomalous situation, but also the correction of a birth boom [1]. Maybe cultural mindset will again change and prevent over-correction.
Pros and cons, you can't look just at this example. Also, a project as big as Brexit takes many years to play out; the transition has barely begun, the conversation is futile at this point, and will be for years.
"the sound would disappear when I stood up" - doesn't sound like tinnitus.
There are things like heavy machinery which produce low frequency vibrations which are audible in some rooms depending on acoustics. I once lived near a rail line which was having work done. In one room I experienced the hum, no others, and it would stop when I stuck my head out the window. See https://en.wikipedia.org/wiki/The_Hum
I thought I wouldn't comment on this because saying it's a scam would just get me downvoted regardless of how I present it - colour me surprised, it seems to be comfortably the majority sentiment.
Not just an echo chamber - it's something to sell. Whether or not it measures up to the hype doesn't matter once you've been paid for it. This is not the first buzzword from tech, and won't be the last. The finance industry is another example of an industry that will jump on a buzzword to sell - currently also AI.
