Is the independent station once broadcasting on channel 4 still in service? Their antenna tower was in Trafalgar, IN, which should be close enough to receive, given reasonable terrain.
I admit it: I made up the part about mules, but the math didn't work out for horses; they are too fast. And clearly, Kentuckians aren't exclusively pedestrian (that's the only other way I can think of to assert such a low average speed).
Are you saying it really was a typo?
By the way, I drank my first bottle of Mezcal in Louisville. Good times.:-P
Everyone in Kentucky drives mule teams, unless they're rich, in which case they drive horse-drawn carriages. Mules are slow enough that miles and hours are effectively interchangeable. Horses skew the speeds upward somewhat, but it's really negligible in the context of internet broadband.
So if the satellite is moving 7km/s, its kinetic energy would be about 24.5 MJ/kg as well. Six percent of that would be 1.47MJ/kg. I found a value of specific heat capacity of steel online to be 620 J/kgK, which is probably ballpark for most steel, but may be high for the satellite as a whole. That gives a temperature increase of over 2300 degrees, so it could melt. But the latent heat of fusion is around 250 kJ/kg, so taking that amount of heat away would give us 1900+ degrees increase. Still meltable.
Of course, these specific numbers apply to the WAG (I'm assuming it was a WAG) of 6% absorbtion of energy and neglect potential energy, as well as ablation. So, are we almost there?
...but how do you know that there was nothing but a layer of steel surrounding the tank?
Why would there be anything else?
Because steel is heavy? Maybe the lighter weight of aluminum or titanium would be worth the extra expense if not as much mass needed to be lifted into orbit.
Also, the numbers quoted above about melting points and re-entry temperatures are pretty specific considering the variables. For instance, what steel alloy is referenced? My limited research suggests that carbon steel melts above 1400C, for low values of carbon. What is the thermal conductivity of the item that heats to 1400C during re-entry? Presumably, the potential energy of the satellite in orbit gets dissipated as heat, but how quickly and how much goes into the air?
How about evaporative cooling of the fuel tank as the fuel boils off through a pressure relief valve? That could keep the tank temperature low enough not to melt.
Anyway, it seems there are a lot of certainties thrown around in this discussion that may not apply. I guess there's not enough nerds here...
Well, crap. There was a transcription error between my paper scribbles and my kepboard during the number crunching. At least the error is in keeping with the inherited subject line.
Currently, the kinetic energy of a jet is turned into noise and heat by a complex mechanism that uses a cable to compress a cylinder, forcing hydraulic fluid through a valve into a pressure vessel. If some of that energy could be reused, it might be enough to power a rail gun...
Let's see...40,000lb jet, 130knots (unit conversions and other math omitted)...should be about 80MJ. Every time you land a jet, you can use the rail gun, even with some efficiency losses.
Yes! The apostrophe replaces the "o". So "American's" is just a contraction of "Americanos". It makes sense now.
The Oakland A's uses the apostrophe either to contract "Athletics" or to distinguish from the English word "as". The second reason is more useful for other acronyms, and doesn't rely on varied capitalization to distinguish between the root acronym and the pluralizing "s" on the end, such as "MRI's".
Now, if we could get rid of these damn "quotes"...
I'm posting this from a library right now. (Using a personal laptop.) Oh, and 'antisocial' isn't the opposite of social, exactly. It refers to the desire to tear down society, not just drop out of it. I would like to suggest 'nonsocial' for that meaning. On an unrelated note, involving socializing, I just talked to a woman in this same library, who happens to have a laptop as well. The internet can be a great way to meet real people in the real world. As long as they don't have internet access at home.
There are some quantum effects that cancel out the time dilation thing. While you are travelling at hypersonic velocities, your death is much more likely; in fact, you are both alive and dead at the same time, in proportion to the appropriate actuarial table. When you slow back down, that dual state resolves itself into one or the other. Statistically speaking, it evens out pretty well with the extra seconds you may gain at the end.
That's just the theory, though. In practice, you are much more likely to die in a fireball.
The FA-18C Hornet is an old plane with short legs; it is not the replacement for the F-14. The FA-18E/F Superhornet is 30% larger than the C model, and has respectable range for a fighter. It is the Superhornet that is replacing the Tomcat.
Interestingly, the FA-18E/F is being used as a tanker to refuel other planes airborne. Before you say that is a waste of a fighter, consider that the tanker can go just as fast as its customers and maintain a radar picture of the tactical environment while the fuel receivers have their radars off.
I was thinking of a one-to-one pairing that is advertised as keeping unwanted phones off your network -- a wardriving defense. Of course, it would also be zero-config as bait and vendor lock-in for the seller's benefit.
Yours seems to be the only comment that actually addresses ink patents rather than cost of ink or cartrige incompatibility....
It seems that the patentable formulations would be in the realm of viscosity control and drying agents. Pigments themselves have been around long enough that we may have all we need. I am fairly sure we have the ability to print a full visible spectrum, at least as well as each color might be found in nature. In that regard, if anyone tried to patent half-tones (or whatever they call the light magenta, light cyan and light black you get with the six or seven color systems), I would loudly proclaim "bullshit."
On the other hand, if the claim is more of a "you stole my formula for supermagnaflow," then I am in favor of patent protection. The way I see it, colors are obvious advances in ink, and should be unpatentable. Miracle substances that don't dry out until they touch the paper, never run and never fade seem like they have some room for creative innovation that should be encouraged.
Nobody here has yet mentioned foam earplugs. They are designed to block noise. High frequencies are easier to block than low frequencies, so they should be attenuated pretty well by earplugs. I don't have any firsthand experience with the Mosquito device, so I can't give a firsthand report of effectiveness, but foamies make many loud environments tolerable. They are also cheap, so you may only need spend pennies to counter an expensive device.
A bulk package of foamies can be posted near the edge of the affected area for use by passers by.
That type of thing was really apparent with the Superbowl, which was referred to by many media talking heads as "the big game," presumably because they were barred from using the actual term.
I guess now I'll have to go into hiding or pay a penalty. Damn.
Presumably, those highly-paid NSA personnel are also well-trained, at least enough to use disposable pre-paid cell phones that they purchased with cash somewhere without security cameras.
Seriously, many government phones have stickers on them that say "this line subject to monitoring," or similar. Also, we have a rich culture of spy thriller movies where the protagonists go through extraordinary lenghts not to have their phone calls traced or monitored. Anyone contemplating leaking information to the press should be well-prepared to render these phone records useless in tracking them down.
Quick! Name the label for one of your favorite, non-Beatles albums. I'd bet you can't do it.
Well, I guess I wasn't quick, but Swan Song and Waxtrax come to mind. I can think of a few more, although they aren't as strongly associated with favorite albums: Geffen, Atlantic, Self Immolation. (I just threw that last one in there because it seemed out of place.)
Having thought about it a little while typing, I now realize that I haven't payed attention to any recent record labels. That is, I can't name the label for any recent albums, so your point stands.

(I probably deserve a pi in the face for attempting that pun. (and this one))
I always thought it was higher, around 80%.
But seriously, my favorite statistic from Slashdot today is this:
I suppose it's probably not made up, but it is meaningless.Is the independent station once broadcasting on channel 4 still in service? Their antenna tower was in Trafalgar, IN, which should be close enough to receive, given reasonable terrain.

How about a network appliance that talks to the phone over IP and forwards the digitized audio to and from the handset?
You know, an otherwise useless box to take up a port in your router that requires no administrative skills to set up.
