Chemical rocket engines dump heat into the exhaust gases but in a vacuum radiators have to be huge and heavy to get rid of significant amounts of heat from something like a nuclear reactor.

You could use a nuclear lightbulb style gas core reactor and either ablation or pure photon drive.

You are assuming we have to pander to pilots preferences. Just TELL them, "you will be videoed or alternatively you can choose another profession".

And some percentage of them will, which makes the available pool of pilots at a given price smaller, resulting in either lower quality or higher prices or both.

Could you elaborate on what you mean by "alter orbital structure and energy levels"?

I mean part of the electrostatic attraction between atomic nucleus and orbiting electrons should be countered by expansion of space between them, which in turn affects stable electron orbits. In fact all forces should get weaker with distance faster in an expanding space than in flat space.

Electromagnetic force is mediated by virtual photons, who's wavelength gets longer as space expands, thus sapping electromagnetism of some of its native strength and somewhat altering the lowest-energy point of all structures held together by it.

I was a little confused when I saw that wording in the story, and now that I'm hearing this wording is the important part, I'm getting a little concerned. Are we not all citizens? Have we been divided into citizens and ruling class, now?

We've always been divided into serfs and lords. Human spirit simply doesn't have the strength to resist using power to get more. The lords, blinded by the seeming invincibility of their position and the system which grants it then end up draining that very system to the point of collapse and revolution, and the cycle repeats.

Whether it can be broken is anyone's guess. Democracy has slowed and complicated the gravitational collapse of current system somewhat, but it couldn't alter the end result, since all manifestations of power in our societies are not under democratic control, and are thus free to join biggest existing masses of power and make them even bigger.

I'm all for popularizing science among all citizens, but I'd rather we word that as "science for the masses" or something.

That very desire should already answer your question. As our masters keep telling us: if you have done nothing wrong, you have nothing to hide.

That the thing about dark matter... it has a perfectly reasonable explanation (WIMPs). It's not that weird of a "thing".

I dunno. Usually when a theory requires more and more unseen entities over time it's a sign that it's time to replace the theory. We know General Relativity is incomplete, both because it doesn't take into account quantum effects and because it has internal contradictions - specifically, it assumes a continuous spacetime geometry but predicts non-continuous points (black hole singularities). Most likely Einstein simply missed some observer-specific assumption - for example, GR assumes mass-energy has an exact distribution rather than probabilistic one - and thus GR is not completely general.

A question I've had for a while... if space itself is being inflated (or any sort of mathematically equivalent scenario) - everything inflating in all directions at all scales - wouldn't there be some sort of weak radiation signal from electrons expanding into a higher energy state due to dark energy and then collapsing back down?

No, because a continuous force wouldn't drag electrons up and then let them drop back down. What it would do is alter orbital structure and energy levels. But how they'd be altered depends on how quantum mechanics and GR combine, which we don't currently know.

It appears this German guy knew that, and was hiding his problems from his employer and the regulatory agencies that license his operation of giant passenger aircraft.

So what happens when you remove doctor patient confidentiality? The other depressed people will not see them and will still fly, only without having received psychiatric help or medication. That makes the risk larger, not smaller.

Experts on suicide say that the psychology of those who combine suicide with mass murder may differ in significant ways from those who limit themselves to taking their own lives.

No shit, Sherlock.

"Esp. of a woman: sexually promiscuous or provocative, esp. in a manner regarded as vulgar or distasteful.". So you're injecting your subjective views into what looks mean and attaching a value judgement into that.

That description is what whoever picked the booth babe "uniform" probably went for. It's catering to a specific fantasy: "You're a pimp and these are your bitches, if only you buy our product." You know, the exact one a cynical - though not necessarily very smart - marketer would use to sell to a stereotypical nerd.

No it doesn't. It means more demand. Read up on Jevon's Paradox. As a resource (including labor) is used more efficiently, demand for it goes up, not down, because of greater opportunities. It would only go down if the Lump of Labor Fallacy wasn't a fallacy.

The problem is, people aren't coal. A coal seam can sit unused for a hundred million year with no ill effects. An unemployed laborer can't. He either gets a job fast or falls into poverty. Supply of labour cannot go down in response to market situation; the only thing that can go down is the price. And as price of labour falls, demand for products falls, because people who get paid less can't afford as much. As demand for products falls, more people get unemployed, and you have a nice little vicious circle going.

It's what's happening now. Cheap credit kept a fundamentally broken system going for a while, but now that well has ran dry and it's collapsing. Keeping it going forever would require citizen pay, or credit without expectation of repayment. But I doubt the rich and powerful will accept the economic independence this would bring to lower classes, but will continue fighting tooth and nail to retain their power all the way to another bloody revolution.

As a side note, economy is full of "fallacies" that only apply with certain preconditions, for example that the resource can go unused with no ill effects. Ignoring those preconditions makes them a fine way to explain away any need to change. The problem is, reality won't go away just because you ignore it, and reality is that lots of people are unemployed, those still employed are living under constant pressure and fear, national and personal debts are sky-high, and nobody seriously expects any of this to get better in the foreseeable future, at least outside official speeches.

It's only those damn Russians are doing this, all other countries are saint.

Yeah, because that makes it all OK then.

Your comment is designed to distract from the issue at hand, shut down intelligent conversation on the topic, and imply the wrongdoer is just fine because, by implication, "everybody else does it, too" (no evidence to said implication provided, certainly not proven, and probably not true), all without contributing a single creative or new thought to the discussion at all.

Nice job, (Russian?) troll.

Then explain why an American worker today can be more productive than his or her predecessors, yet paid a substantially smaller fraction of the proceeds from his or her labors?

Greater productivity per worker means less demand for workers. Less demand means lower price. Thus, more productive workforce means worse-paid workforce.

Yay capitalism.
