There are many "aerodynamic winged drones" that are battery-powered - Raven, Puma, and the various flavors of Switchblades are a few examples - not to mention unmanned ground and underwater ones. And notably, the Ingenuity helicopter that performed so well on Mars.

Weight and drag are key factors in endurance for air vehicles, which is why long-endurance quadcopters are rare. Even the fuel-carrying drones are weight sensitive. Designers take great pains to make the airframes as light as possible to increase endurance and payload/fuel capacity. For example, the MQ9 Reaper carries up to 7,850 lbs of payload and fuel, but its unladen weight is only 4,900 lbs, including the engine.

Water tight? I'm struggling to think of a single Apple computing product that even approaches being water tight. Go ahead - pour a few ounces of water on your MacBook's keyboard or drop your iPhone in the toilet and let us know what happens.

That really is an interesting paper you cited. As a counter argument, I give you Flat Earthers, Moon Landing Deniers, and Anti-Vaxers. There are others, but those are shining examples of groups of incompetent people secure in their belief that they are correct. And now I suppose I will get a flood of replies from members of those groups telling me what a sheep I am.

Actually, lots of humans think they know more than they really know. Dunning and Kruger published some research on this, if you're interested in learning more.

Almost. What's your definition of "larger primes"? Larger than what?

Take out "ever", change "release" to "market", and append a specific date more than five years away but within a decade or so and you might get a few takers. But you might also want to qualify what you mean by "commercial", because it is certainly possible to market a product with a price so high that the only organizations able to afford it are governments. Or Elon Musk.

Same here, though I strongly suspect it was before you graduated - the first HP scientific calculator came out in my senior year, and nearly caused a riot in one of my classes because one of the students bought one and it was a LOT faster than the slide rules everyone else was using.

Anyway, I recall a few open-book exams, but mostly you were on your own. My physics 101 prof was pissed off at the class because hardly anyone was doing the homework, so he announced that everyone's final grade would be based entirely on their final exam results. I stayed up all night, doing all the odd-numbered problems at the end of every chapter in the textbook while I was waiting in vain for the Apollo 12 video camera to start working again (Astronaut Alan Bean accidentally pointed it directly at the sun while mounting it on a tripod and burned out the vidicon pickup tube sensor). It paid off - that was the one and only quarter I scored a 4.0.

According to the Oxford English Dictionary, it appears to have been exhausting people like you for quite a long time.

Except a blockade is actually an act of war. Thus, hostilities have not ended, notwithstanding any "War Powers letter" and the President's claim to the contrary.

Why does that have such a familiar, current event-ish ring to it? Oh, yeah....

That would be fine if ALL the gains from "how well the whole capitalism thing is working out for them" were taxed as ordinary income. "How well the whole capitalism thing is working out for them" frequently goes like this: instead of selling a bunch of the stock you own to raise money, use it as collateral to get a low-interest loan. Congratulations - you've avoided capital gains tax on selling the stock, the loan proceeds are non-taxable, and your stock stays in the market where it can appreciate in value. Bonus: if you use the loan proceeds to buy more stock (there are restrictions on this), interest payments on the loan may be tax-deductible.

I guess it's time to brush up on the golden rule: he with the gold, makes the rules.

No problem. Just pump up the volume.

That's caused by some of tiny threads that attach your retina to the back of your eyeball being torn loose. Then they become "floaters", providing a permanent reminder of the experience.

My wife had so many floaters in both eyes, her retina specialist at UCLA's Stein Eye Center performed a procedure that purged her vitreous fluid and replaced it with saline.

Perhaps you should consider being a bit more selective about the films you choose to see? When my wife and I go to the cinema, the ratio of previews is about 10:1, films I wouldn't want to see vs films that look interesting. Not at all interested in the latest Marvel/DC/comic book retread, which by itself eliminates a lot of unwatchable trash. That means we don't go often, but than in itself makes it more of a treat.
