... that all planets/solar systems collect their water and air at the time of their formation. Some systems may experience a longer and/or later period of comet collisions bringing water, gasses and possibly biological material. If that period of collisions persisted after the star had cooled down, the lost water would be replaced. And, as TFA states, a period of high solar energy can result in the buildup of some elements like oxygen.
We consider how improbable life on Earth is given the odds of multiple events occurring at just the right time. But its possible that numerous different paths can be taken, each with their own likelihood, that lead to the same point. Its possible that the conditions for life involve nothing more than a planet settling into some 'sweet spot' of biochemical stability, where processes act to stabilize the environment around that point for a time sufficient for life to evolve. Whetever does evolve will be suited for that particular stable point.
It's about the volumetric efficiency of an internal combustion engine. Which swamps the effects of drag at these speeds. Or were all those automotive engineers wrong about adding overdrive and more gears to transmissions?
Bicycles are an extreme (and bad) example of air resistance. The coefficient of drag and cross sectional area of an upright cyclist is abysmal. Its like running a drag race with your parachute out.
the chips are the same chips with same antenna pattern as any other bluetooth device using the same chip.
Possibly. These things were probably built based on the chip manufacturer's reference design. If so, it might be pretty easy to certify the new product by similarity* to others already tested. If S. Korea will approve devices based on thhis, it raaises the question of why the Selfie-Stick manufacturer didn't just submit the paperwork.
*Often times, RF module vendors sell 'pre-certified' boards so hobbyists and small manufacturers have minimal or no additional work to do to operate their device legally.
This was sort of my point. It is my understanding that the correct structure of Bridgemanite is not stable on the surface of the earth. So what we find lying around are samples that have been cooled and decompressed.
One of my hobbies involves hardening and annealing metal. And time at temperature is a critical factor (fast vs slow cooling) to produce the desired material characteristics. So I'm not convinced that the stuff inside a meteorite, which experiences these extremes for only a few seconds correctly duplicates something that has been exposed for a few billion years.
But the summary is slightly misleding. The stuff they found came from a shocked meteorite. And it fits the theoretical models of the makeup of the lower mantle. But it sounds like we still haven't gotten a significant sample from inside the earth to validate the theory.
A workable robot with a humor setting anywhere near 75%? Not going to happen IRL. That was investigated with the Bender character in Futurama and look at the mess that turned out to be.
Maybe not. We don't know if the drone was being flown by an inattentive idiot, a jackass that thinks buzzing planes is good fun, or someone with more destructive motives.
I imagine most municipalities want the option of excluding people with certain convictions from the pool of taxi drivers. DUI, armed robbery, sex offences, etc. might be a few that would disqualify one as a cab driver.
5) If you can wean people off diesel for use in private vehicles (or keep it from being adopted widely like in the USA), then you can manipulate the gasoline supply during oil shortages or war time without interfering with commercial trucking and other operations. All the government needs to do is to call refineries and change the fraction of diesel vs gasoline and no rationing system will need to be put into place.
If you maneuver a lightweight craft into the proximity of a much heavier, faster one your ability to maintain control of it may be reduced to near zero. It could easily be flipped into an engine intake or control surface by the turbulence of the larger craft.
Or the turbulence could just damage the drone, rendering it uncontrollable and dropping it on the public below.

cities could just stop going after Uber and make them pay a "medallion tax"
Except then Uber drivers wouldn't be part time, "picking people up whenever they happen to be going that way" type service. They would have to work and earn enough for the medallion mortgage/rental. And as they become ful time drivers, the service will become indestinguishable from a taxi service.
Better solution: Do away with medallions as a tradable asset and move to a permit system. Have insurance, maintain your car and not have a criminal record and for a fee sufficient only to cover the program cost, you get your permit.
The medallion system was intended to limit the number of cabs on the road. Before it was put into place, everyone with an old beater could hire out as a taxi service. The roads were jammed and the prices were cutthroat (and some drivers as well). A permit system won't fix this problem directly. But by holding minimum standards up, it can serve to keep some of the low budget/low quality cabs off the road.
the Spratly Islands, where it went to zero elevation. Likely shot down by China.
Unlikely. Too many people with territorial claims on this area are watching it intently. And most of them would be motivated to point the public finger of blame at an adversary should a shootdown be detected.
Why wait until debris hits the beach? Some aerial reconnaissance would provide positive proof of the assumed impact site by spotting stuff floating.
Its also possible that the plane 'crashed' in a manner so as to produce a very small amount of debris. Pretty much the same way Flight 1549 went down on the Hudson River.
We have that option where I live, in the form of a public utility district law. Voters can elect to buy out the private business. And a few, in rural areas, have done so. But the capital price (which the public would have to raise through bond issues and taxes) is huge.

It's not about the gearing.

And Bluetooth too - the 30' menace.
How do you know it only has a 30' range? These things being untested/uncertified and all.
The problem is, cars have optimum fuel consumption per distance travelled at ~90km/h (~56mph).
Perhaps your car does. Mine isn't even supposed to be in high gear at 56 mph.
So we can enginer our way out into space and through wormholes. But we can't cure* a crop blight?
*OK. So the resulting food would probably lose its organic certification. And hipsters would rather die than eat GMO.

Why 'no criminal record'?
I imagine most municipalities want the option of excluding people with certain convictions from the pool of taxi drivers. DUI, armed robbery, sex offences, etc. might be a few that would disqualify one as a cab driver.

Depends on what you mean by 'control'.
If you maneuver a lightweight craft into the proximity of a much heavier, faster one your ability to maintain control of it may be reduced to near zero. It could easily be flipped into an engine intake or control surface by the turbulence of the larger craft.
Or the turbulence could just damage the drone, rendering it uncontrollable and dropping it on the public below.
