Bats tend to use very high frequencies (100kHz+ = 3mm wavelength). Humans do most of their talking and hearing below 2 kHz = 15 cm wavelength. At the 15cm level, glass and a brick wall are both featureless and flat reflectors. At the 3mm level, glass is a lot smoother than a brick wall.
Native speakers of American English? About 250 million. Native speakers of British English? About 50 million. And guess what? It doesn't matter because British spelling belongs in British media and American spelling belongs in American media. You'd get ticked off if you were being told about 'centers' end 'elevators' in your favorite sites, wouldn't you?
For insisting that American English be used on an American site? Next you'll be calling me a racist for demanding that the ham in my ham sandwich come from an actual pig and not a turkey that self-identified as a mammal before its untimely demise.
I'd say the same about each and every bean counter who floats his way up to the C-suite unless and until he gets hard results instead of just making pleasant-sounding noises and lofty promises. As a general statement...I'm still waiting. Elon Musk is only 2/4 on his ventures. I don't know who this VW joker is, but he probably didn't work his way up from the engineering shop.
No. It's quite real. I've seen them with my own eyes. What's a hoax is the claim that it's better than my ten year old Chevy that fills up in two minutes, can be filled up out of a man-portable container of gasoline in an emergency, goes at least 400 miles between fill-ups, has roughly the same range regardless of whether it's hot or bone-chilling cold, and would cost new about a quarter of what a Tesla costs sans federal and/or state bailouts and subsidies.
If I were a big auto CEO, I'd go all in for synthetic fuel. So that I'd only be promising to invent a not-quite-pie-in-the-sky technology instead of a totally-pie-in-the-sky technology.
I've said it before and I'll keep on saying it: batteries are a terrible energy storage medium for transportation from an efficiency, safety, and reliability viewpoint, and not because it needs more money but because it can't get out from under its fundamental physics. While electrons are easier to transport over distances, molecules are much easier to stockpile and transfer without loss. Carrying your own oxidizer with you is stupid when the air is 20% oxygen, not to mention that riding on a ton of fuel and oxidizer packed in close proximity is silly. And lastly: IC engines have consumables yes, but they are field-serviceable and don't require complete remanufacturing to maintain their efficiency. Batteries can't do that. Not now, not in a hundred years.
About weed, not LSD, but the point remains. It makes you think funny, and believe you're being profound. But you're just getting high.
Same thing with dreams. Make perfect sense while you're having them. Make absolutely no sense once you're awake and thinking clearly. Occasionally a good idea will pop out of the noise. Just like occasionally you'll win the lottery or have an apropos captcha in the comments section.
I like my coffee, but the answer to your question is that it's hard to say because around the same time, clean drinking water/better sanitation practices also became available en masse in the major cities, reducing the need for people to drink beer instead of water. Factories and scientific research tend to run better when everyone isn't a little buzzed.
Conservatives (and everyone with a brain) has been talking themselves until they're blue in the face over the federal bailout for the rich known as National Flood Insurance. It's just that people who tend to get into hysterics about Evil, Evil, Conservatives!!1!one!! about every issue can't get past the fact that we're saying that something the government does is bad, therefore a good liberal must defend it, no matter what.
We all do. More work = bigger economy = more wealth = more prosperity for all. How the hell do you think we're still the richest (and the richest per-capita large nation) on Earth after forty years of globalization? On paper, all of that should have gone away to China and India and Mexico and Central America by now, but it hasn't.
Done in moderation and allowing for individual variation, it will make you about 8% more productive. In the aggregate. You know, 'cuz 4/50 = 8/100.
People tend to understand that. Which is why even folks with more generous vacation time tend not to take them unless they have a bona fide emergency. I have more than six weeks vacation a year. I let it pile up because I'd rather spend that time getting my job done. So do most white collar and salaried people. Hourly people have an even stonger incentive. What you Eurolovers tend to misunderstand is that people here work harder because they want to, not because they have to.
If you thought I was trying to win an argument by winning a word game, you'd have a point. But I'm not. So you don't.
More information is better than less information, but only if it's used properly. My strong suspicion is that while they're getting all this data, they don't have a good way of using it on live, on-the-road, autonomous vehicles without human curation. So I don't think they're using it for Waymo. I think they're using it to make their streetview images stitch together better.
The corporate LAN I have at work has an internal DNS where every internal site is a single word like 'hr' or 'training' or 'whatever.' The URL keywords feature has to be turned off so that when I type 'hr' to get to the HR page, it doesn't search for 'hr' on the open internet or try to go to 'www.hr.com.' Didn't think this one through, did they?
Which would be all well and good until things move around. Like with road construction. Utility work. New construction. Demolition. A nice shiny new traffic light pole. Autonomous cars are hard because while the typical street or highway is an artificially constructed environment, it can be a very dynamic environment.
I'm not so sure skepticism is merited in either direction.
All advances in physics to date have been based on controlled laboratory observations. With relativity, our ability to make macroscopic measurements across the full range of velocities and energies is quite limited. While we can measure gravity waves and deflection of light, and make inferences based on the behavior of relativistic particles in cyclotrons and linear accelerators, what we have not been able to do is make a macroscopic measurement of matter at relativistic speeds.
All we can say is equations that fit observations at the microscopic scale with matter and at macroscopic scales with photons have a singularity at v=c. The only way to know if that's real or if it's a mathematical artifact is to make that measurement in real life, which I'm sure you'd understand is very hard to do.
Here's another kicker: our ability to measure the force of gravity is limited in accuracy to the point where there could be a whole other force on matter that acts on the scale of meters and is just as strong as gravity, but we wouldn't know because our measurement accuracy is limited and we can't tell it apart from GM/r^2, if it's there at all.
As for LIGO, it's got crap sensitivity, in the grand scheme of things. It can hear two black holes merging, and just barely. So I wouldn't take absence of evidence as evidence of absence on that just yet. All we can say is that no one is bombarding us with RF or light pulses and (maybe) no one is shooting off gravity waves in our general direction. Beyond that, speculation about the presence or absence of other intelligent life in the universe is pointless because there's no way to tell if it's grounded in any sort of reality.
Here's a good analogy: The ancient Greeks noticed something funny happens when wool is rubbed on amber ("elektron"). Three thousand years later, Maxwell wrote his equations, another forty years later Marconi turned it into practical communications technology, and it took another century for it to become widely used. Where we are now with relativity and LIGO and astrophysics is probably closer to ancient Greece than it is to Marconi or even Maxwell.
You read it again. It's only "activism" if any peep that doesn't toe the company line is activism, if "Boss, I don't think that's a good idea and here's why" is activism.
Well, they've been batting a thousand for the past ten years in my experience, and I'm paying for it anyway since it's free with my insurance, so...Imma keep on getting it.
I prefer to seek out the positive from this depressing possibility. Do you suppose it's possible to get a conspiracy theory going that there is no moon at all?

Let's start with the solar panel companies.

can't be taught it. If you haven't learned fundamental things like "there's no free lunch" by the time you turn 15, you're hopeless.
to use on an American site. Let me guess...that's right! It's msmash. Copying and pasting from British sites since...
is ASCII.
Also: go ahead, explain to me why it is that my computer needs to have a turd glyph stored on it.

'hr' + ENTER = 3 keystrokes
'http://hr/' + ENTER = 11 keystrokes.
Maybe eight extra keystrokes isn't anything to get militant about, but don't pretend it's an improvement over three.
