In addition to its lower drag, it has higher thermal conductivity than air. Reduces certain heat effects.

Joining interested others to ask for any links to your work. Thanks!

For anyone interested in the story of the Iridium system, including its many near-death business episodes, I can recommend "Eccentric Orbits", by John Bloom.

She might well be happier in a different development environment. The link [1] is to a 1996 article that describes organizational aspects of Space Shuttle flight software development. The priorities were understanding and perfection, which

Genuinely curious - what's your tax haven?

I read what you wrote as affirming my thought. The constraints of DoD CSI, DO-178B, and the smart card industry focus are all embodied in regulations , which precede legal retribution. If a company busts the regs, it can be sued. But the f

But the ease of creating companies and abandoning them or otherwise obfuscating their liabilities says that they won't be the ones paying dearly. In short, I think regulations will prevent more damage than post-hoc legal retribution.

Bringing up Webb is a six-month process after it gets on station. According to [1], in months 2 and 3 the mirror positions are adjusted to bring them into optimum optical alignment. I haven't found anything on the type of actuators use

EMP, or pulses, are broadband. Take the Fourier transform of a short (~ 1 nsec) pulse and you'll see significant energy up through several GHz. In the EW environment, broadband pulse radiation can couple to slots, wires penetrating a F

FYI - My wife, who does collaging, just got Primitive off MAS, and she loves it. She's running it on an older iMac. She's impatient, and will probably go buy a MacPro in the morning. Thanks - I think...

The raw materials are cheap, but growing crystals of SiC isn't easy, and it took quite a long time to work out the growth processes. It helps that it's more or less conventional crystal growth and doesn't require super high p

I think your rhetorical questions distill down to: "Is it unreasonable that societies expect conditions improve over time and act so as to bring that about"? No, I don't think that's unreasonable at all. I think it'

Charles Stross in his Laundry Files series may have pioneered that path (although no movies that I know of). Do the wrong transform in, say, a Hilbert space and something quite horrible may come after you.

Modeling, like COMSOL. Runs very much faster when RAM is enough to keep it from accessing disk, even when disk is an SSD.

But it's also about outcomes. As I understand it, Altman considers a Trump win a bad thing for America. There's no inconsistency between, on the one hand, repudiating Thiel's material support of Trump and, on the other hand,

Of course a decent person can support Trump, if by decent you mean hard working, honest, responsible, etc. This isn't about the decency or not of Trump supporters. It's about indirectly supporting Trump and thereby increasing the

You can. Here's one company that does (ceramic) fiber reinforced aluminum. http://specmaterials.com/fra.html There's lots of research literature on carbon nanotube reinforced aluminum.

For an understanding of how America got to its current circumstance regarding drugs, I strongly recommend a book, Chasing the Scream: The First and Last Days of the War on Drugs, by Johann Hari. I found it an extraordinary read.

Downvoted because you offered a uselessly simplistic characterization of many peoples' responses to complicated phenomena.

The only place within an hour of Palo Alto where this might have been true is East Palo Alto. It's adjacent to PA. It is still a somewhat dangerous community. That's changing. Prices in EPA are now >50% of equivalent housing in

Some reasons why somebody with less than a decade left might pick a long-term stratagem: • On the basis of kin selection, they would pick policies that favor their offspring - preserving one's DNA contribution is a powerful motivator.

I'll suggest it's worth a retry. Those first few pages are a slightly cryptic intro to a complex, intelligent, and thought-provoking tale. YMMV, of course.

Why would one have a greater expectation of shortsighted measures from a gerontocracy vs. governments composed of, say, those in middle age? I don't understand why this would be a function of age.

It's not dumb. When corporate executives make decisions, they're explicitly constrained by legality. Morality is negotiable. And relative.
