You might be able to double-blind the Faraday cage if the screen material consisted of (for the active cage) wire overcoated with plastic and (for the inactive cage) fiberglass threads overcoated with the same type of plastic, the intent being to provide two cage materials that look and feel alike (bump into them and they both have the same stiffness) but only one of which provides the RF shielding function.
make me feel better about humans. I'm glad a bunch of talented people decided it was a worthwhile goal to make a kid happy. Hope he finds an even (faster/shorter) Kessel run!
this camel's back. The idea that the OS on my iPhone will serve me advertisements without my consent and without my ability to block them is making me rethink whether I want this thing in my life. I paid for the phone, I pay every month for the data service, and the advertisers are going to use my paid-for device and contract to generate revenue, with nothing coming my way? And I'll incur the costs of distraction and time wasted viewing those pushed ads?
Having an iPhone is convenient, fun, and cool....and I can have just as great a life without one. And if it comes down to it, I can migrate to Linux from the Mac OS I've used since 1984.
Remember, the expenses incurred by the RIAA in these and other similarly insane actions are by and large tax-deductible business expenses. In other words, the American taxpayer is footing the bill through reduced tax revenue and corresponding loss of services and/or increased taxes elsewhere.
Get her her own computer. Do the best you can vis a vis protective software, and resign yourself to having to do periodic maintenance/resurrection on her machine. Discuss with her and persuade her to do nothing important (e.g., online banking, billpay, etc.) on her computer, but only on yours, on which you maintain all the protective stuff and protocols you can. It is possible she will learn over time what's happening and why she needs to not do what she now does. It's also possible she won't. Your marriage is way more important, prioritize that at the top and make the computer issues conform to that.
It's fun to observe from the periphery - this result, the recent confirmation (maybe) that neutrinos have mass (otherwise they couldn't interconvert among their three types)...more and more cracks are appearing in the Standard Model. It's exciting.
And probably the answer is 42.
"Debeers is now allowed to operate in the U.S. because they are a price fixing monopolist."
Nope. Although DeBeers is a monopolist as you say, it is now allowed to operate in the US not because of their monopolist status, but because they settled the various lawsuits pending against them in the US, some of them quite longstanding. See Wikipedia article on DeBeers. As a result, it is now possible for DeBeers' employees to come to the US without fear of arrest. Prior to the settlement, if you were a scientist employed by DeBeers and wanted to attend a conference in the US, you couldn't.
And IIRC, it took 13 tries before we got an Atlas to fly without going boom. There's a reason they call it rocket surgery....or brain science....or whatever, it's hard to do!
No, Falcon 9 was never intended, nor did it have the delta V needed, to achieve escape velocity. Orbital velocity (LEO) ~ 5 miles/sec. Escape velocity (Earth) ~ 7 miles/sec. Nowhere enough propellant on board to achieve the latter.
If there was an engine restart after the ascent burn, it may have been an attempt to raise the perigee, a routine astrogation move to circularize the orbit.
would be consistent with the increasing roll rate apparent in the onboard video as the second stage approached burnout. Haven't gone to YouTube yet to review, but it was clear that although the vehicle made it to orbit and may have made it through the intended insertion window, attitude (roll axis) control was not happy. I hope SpaceX will discuss what happened...purely as a matter of engineering curiosity, I wonder if it was a problem with roll G&C or whether a nozzle/bell burn asymmetry put a torque on the vehicle that was beyond G&C roll control authority, or ???
"Necessity" is a recognized legal defense that can be asserted successfully in some circumstances. The circumstance you describe would very likely support use of "necessity" as a defense to the charge(s) of B&E, burglary, etc. in procuring Band-Aids to save a life. This isn't about entitlement.
I had a Moto Razr, unlocked too. Couldn't stand the UI. Threw it in the trash when I got home after buying my iPhone.
Potential longer-term effects on turbine engines

Thanks for posting the link to the Finnish F-18 engine photos. The airborne dust is clearly accreting in molten globs on hot section parts. These mixed oxide/silicate blobs may react with hot section materials - not sure what the specific materials are in the F-18 engines, but they're commonly nickel-based superalloys, often with ceramic thermal barrier coatings. I think the volcanic material might form eutectic (lower melting point) compounds with either the thermal barrier coatings or the underlying alloys. This won't cause outright engine failure, but it could easily lead to accelerated blade or combuster erosion, requiring more frequent maintenance. It will also degrade fuel efficiency. Not such a big impact on military flight operations, as they will have little trouble getting extra funding for this unforseeable circumstance, but the airlines will see additional maintenance requirements eat very quickly into their bottom lines. AFAIK, there's not much of a database on turbine engine degradation modes due to long-term flight through sub-micron volcanic dust.
They have intelligence and creativity. Their biggest challenge will be isolation from the corruption that seems endemic to Russia in this time. Corruption is pure poison to economic systems intended to be based on merit in markets. Like adding >300% to your company's overhead...how do you compete, even with fantastic ideas/tech?
It's nontrivial. KE = mv^2/2 (Joules in the MKS system). M = 2800kg, v=6000k/hr = 1,667m/sec. KE works out to about 3.9 gigajoules, with one metric ton of TNT yielding about 4.18 GJ. So if my arithmetic is correct, this would be more or less like putting a 2,000 lb conventional bomb on the target.
According to the USPTO site, Apple filed this application on September 30, 2008. If this pre-dates publication or sale of the iControlPad technology, iCP is in a poor legal position. I'm not familiar with iCP's stuff, does anybody know when it was first marketed or described in a publicly available form?
No, this is not the law. During the patent's effective period, the holder has no duty whatever to license it at all. The patent holder may choose to practice the patented technology for its own exclusive benefit, licensing nobody else in order to preserve the time-limited legal monopoly granted by the patent. They don't have to practice the invention, and they don't have to license the patent. They can simply let it sit on the shelf and sue infringers if they wish. The only exception to this is that the US government can compel a patentholder to license if the invention is deemed critical to a national security need.
Durham gets around this by assigning its rights or selling the patents to a big boy with a big legal budget. Durham could negotiate a nice pile of risk-free cash up front plus a share of future license revenues. Happens all the time. If you've got a genuinely valuable patent portfolio, there are ways to monetize it even if the potential infringement defendants have lots of $.
As you said, if you publish patentable matter, no matter how obscure the journal, that matter becomes part of the public domain and is therefore not patentable by definition. Further, if you were to try to subsequently patent your published matter, your failure to disclose the prior publication in your patent application (c/w)ould constitute Fraud on the Patent Office, which is punishable by law. Finally, there is no journal so obscure it cannot be found by a dedicated searcher - and when found, your prior publication of your art would lead to the revocation of an issued patent, either through a FotPO charge, or through a petition for re-examination. Short story: if you want to patent, don't publish until after you file the patent app.
Yes and no. Yes, UV is the most energetic light, but there isn't much of it in sunlight at the earth's surface. Most of it has been lost to ozone, Rayleigh scattering, etc. There's enough to give you a sunburn, but no, in terms of the actual amount of power in sunlight at the earth's surface, it's less than 5%. Filtering it to zero to obtain much longer PV panel lifetime is generally a net economic benefit in terms of TCO.
as other posters suggest. Make your intellectual decision based on the rad survey results. Make your emotional decision based on the burden of constant, even though possibly irrational, worry. Dismiss any thoughts of effectively shielding your living space. This can only be done at the construction phase, is incredibly expensive, and is compromised every time you open a window or a door. Post-construction measures like RF reflective or absorbent paints will not prevent RF leakage through what might seem like minor discontinuities, but which act as slot antennas to re-radiate RF energy into a room. There are lots of apartments, it's not a good idea (for several reasons) to fall in love with a particular bit of real estate when you're in the buying mode anyway.
