PFAS are different from soap in that your body can't break them down or excrete them well, so they bioaccumulate. Eating soap is absolutely not good for you, and if it also built up in your body people would be really worried about small exposures to it.
This is newly interesting in light of the recent pentagon UFO revelations (https://www.nytimes.com/2020/07/23/us/politics/pentagon-ufo-...). While these have low credibility, and even if true are likely not extraterrestrial, finding life on mars would change this calculation.
I was curious too - "Paul Galvin wanted a brand name for Galvin Manufacturing Corporation's new car radio, and created the name “Motorola” by linking "motor" (for motorcar) with "ola" (from Victrola), which was also a popular ending for many companies at the time, e.g. Moviola, Crayola."
This is pedantic, but RADAR relies on photons as well - radio waves are just a different frequency of EM radiation vs visible light. A RADAR system emits photons that are reflected and hit a sensor like LIDAR does (or like a camera with a flash does). I think your point that having more diverse sensors is safer stands though.
I agree with the spirit of your comment, but FB certainly CAN pay 15% raises to their lowest paid employees - I imagine w/ very little impact to their bottom line.
This implies race by referencing stereotypes in a way that I find objectionable - noticed you getting downvotes and figured its worth giving some constructive feedback.
This is a good point, but I think individuals care a lot more about their percentile than you would expect - their benchmark for whether their income is 'a lot' or 'a little' is how much they see the people around them making.
It's my impression that the Chinese have more of a maker culture than almost anywhere else - it's a country full of people who grew up in villages and have now built factories and started companies that manufacture most of the world's stuff.
- give a portion of (something) to another or others.
- use, occupy, or enjoy (something) jointly with another or others.
The first one has a lot of positive connotations, and 'sharing economy' startups are definitely taking advantage of that, but I think the second is a totally valid use of the word when talking about 'home sharing' or 'car sharing'. It's actually hard to think of a better term to describe those.
