This whole question was answered decades ago (1970s) with the "foreigner in a sealed room" turing thought experiment. It showed that the person in the sealed room doesn't have to understand english, or even know the answer to questions, provided they are given some simple rules to link words together in a response depending on what words are in the original statement.
There's a similar problem with Slashdot. I see the text that people put in sealed boxes on my screen, but most of them don't understand what they're talking about. Most of them seem to have only simple rules to link words together in response to what words are in TFA.
I say pass a bil that requires ALL analog transmitters to stay online for 1 month.
Broadcasting a red screen with "If you did not expect this, YOU ARE STUPID!" on it in flashing black letters.
Your proposal is that they instead dedicate one transmitter to a warning screen. It doesn't seem like a bad idea, but on closer examination, it has major problems. 1. It will cost US TV stations aboutUS$23 million for the month in electricity alone. 2. It's not clear that it will help -- TV already has warnings broadcast. 3. It will hurt digital TV customers by reducing digital transmit power. 4. It will put more DTV receivers into fringe and no-reception areas leading to even more revenue loss due to lost sales.
Here's details and math:
With the exception of low-power (~250 watt) and Hawaiian (already digital) stations, all TV stations in the US are already transmitting both digital and analog signals. (OK, there are reportedly about 10 stations that don't a second transmitter and will be off for a few weeks while they transition.)
But pretty much everybody is transmitting both digital and analog now, and they're all running the FCC ads for the transition, I bet.
Right now, they've got their higher-power transmitters on the analog and the lower power one on digital. When X-Day comes, they'll switch to high power on the digital and put the low power one back to backup use, or combine output and have one full-power transmitter.
Let's consider WABC-TV just as an example. Right now they reportedly have a 123KW analog and 239KW digital transmitter. So how much would it cost them to keep the 123KW transmitter on for a month? Let's assume 66% efficiency because it's easy to calculate: So the electric power required for the 123KW transmitter is 150% of 123KW, or abou 185KW. At 24x7 that's about 31,000 KWH (31 Megawatt-Hours) per week. Assume 10cents/KWH for commercial customers (2006 data: 15 cents in New York, 5 cents in Alabama). That works out to average $3100/week for electricity alone ($4500 for New York). Multiply this average $3100/wk by the estimated 1750 TV stations in the us to get about US$5.4 million per week, or about $23,0000,000 for the month that you're asking the TV stations to spend, in electricity cost alone, just to broadcast a warning screen.
Additionally, given that 123/(123+239) is about 1/3, that means they're cutting their digital power by 1/3, which puts more people into fringe and no-reception areas, causing frustration for those who have gotten ready, so there's a tremendous opportunity cost there for lost revenue due to lost viewers and reduced advertisement compensation.
That's great! From your page I found https://apps1.seagate.com/rms_af_srl_chk/ which lets you paste in the drive serial number and reports automatically whether it's affected. I found out mine are not. (Supposedly. Thanks, AC!

MIT's not a giant school. Their freshman class is around 1000., which is bigger than it was when I was a freshman, but not as big as a few year ago when they took steps to reduce size.
I think I had a half-dozen big classes the entire time I was there; the rest of the classes were small enough that I felt everyone got enough attention, especially in the recitations, where my biggest beef was the occasional grad student who didn't speak English.
I think the worst was a math professor pressed into service for a recitation section, who would stand at the board, say, "Uh, I don't remember how to do this one. What's the answer to this integral? Oh yeah, it's..." and write down the answer and prove it was right. But I later found out that is actually how you solve differential equations!
Unless it is a pencil-thin or smaller beam, 15kW is just plain not very much. I mean, it's a lot of energy, I wouldn't want it pointed at my couch... but it is only about as much as you would get out of 150 light bulbs. Maybe even less, considering the conversion factor.
I guess it is on the verge of being practical. But not much more, yet.
Well, lessee...a 100mW (20dBm or 0.1W) collimated burning laser will pop ballons and burn dark objects such as electrical tape. This one is 15KW (~72dBm) so that's ~72-20=52dB times the power, or about 15KW/0.1W=150,000 "burning lasers", assuming Northrop-Grumman can collimate a laser as well as some guy on Instructables.

Last time I was at the Silicon Valley electronics flea market I found a vendor selling plastic demo model cell phones for $1 each. None of them did anything, of course, as there was nothing inside. But plenty of people were pawing through the basket and looking at them all.
You might try (1) using twisted pair instead of zip line to your speakers and (2) using ferrite bead clamps, a few turns wrapped around both ends of the speaker cable. But it probably won't help, as it's likely your speakers internal amplifier is picking up the signals directly, as they're cheaply made (see TOA) and poorly shielded.
What will twisted pair do ? Doesn't twisted pair only protect against interference when you have a balanced line with opposite voltages going down each wire?
If the cable is an unshielded pair (loudspeaker cable, for example), RF will be induced approximately equally on both conductors (but, depending what the input circuit of the equipment looks like at RF, current flow into the equipment may not be equal on both conductors). This can also produce a differential voltage at the input (or output) terminals. Output Wiring is Important Too! It is well known, for example, that RF interference is often coupled into the output stage of audio equipment -- for example, the power amplifiers that feed loud-speakers or headphones. There is always feedback around that output stage, so RF present at the output will follow the feedback network to the input of a gain stage, where it will be detected and amplified. This problem is made much worse when parallel wire cable (zip cord) is used to feed the loudspeakers or headphones, and can usually be solved simply by replacing the zip cord with a twisted pair of POC (plain ordinary copper). [Pseudo-scientific advertising hype for exotic cables notwithstanding, it was shown nearly 30 years ago that #12 copper twisted pair (or #10 for very long runs) is a nearly ideal loudspeaker cable.]... As we will discuss later, the twisting of a pair greatly reduces the level of RF that the wiring couples to circuitry.
The interference won't be powerful enough to interfere with the speaker cable (unless maybe it's a REALLY small speaker). It's the un-amplified analog lines that feed the amp that pick it up. Use shielded interconnects, or even optical SPDIF, and the problem should go away. Probably won't help your clock radio, though:)
The lines are acting as an antenna, coupling the RF energy in, probably in common mode, to the amplifier inside the speaker. Of course you're right that an un-amplified speaker wouldn't have this problem, unless the RF is coupled back into the device that's driving the speaker.
In all of these cases, using ferrite clamps of the appropriate mix will help to cut down on common mode RF travelling into the amplified speaker or into the amplifier of the driving device.
Using twisted pair (you can buy really thick gauge wire twisted pair from the usual speaker people, even Radio Shack) will eliminate differential mode pickup of noise.
Using shielded interconnects will do the same as the twisted pair, but you'll still need ferrites on the outside to eliminate common-mode currents.
Optical is much better of course, but it still won't do anything about radiated RF being picked up inside the speaker enclosure by inadequately shielded electronics inside. For that, you need to buy better speakers. Better speakers will be more expensive, but sadly, more expensive speakers are not necessarily better.
whatever happend to the label on the bottom of everything, which states that:
"This device complies with Part 15 of the FCC rules. Operation is subject to the following two conditions: (1) the device may not cause harmful interference, and (2) the device must accept any interference received, including interference that may cause undesirable operation."
obviously the folks that made my PC speakers obeyed those rules, so why is apple getting away with breaking condition 1?
The iPhone isn't operating under Part 15. It's licensed. Your cell provider holds the license from the FCC. They paid a lot of money for it; remember the spectrum auctions that raised billions. It's your speakers that have to live with the licensed world, not the other way around.
The same is true for broadcast radio, TV, police, fire, ambulance, business radios, taxi dispatchers, amateur radio, military, and even foreign licensed broadcast systems. Your speakers have to live with it.

Their blog has a few of the test pictures received (of of Exp. 17 Commander) Sergei Volkov. These were received in Portugal and the US. Other images will doubtless show on their blogspot site one Garriot gets involted.
Of course, it's interesting to note that Hakon Lie has a vested interest in preserving quirks, because his company Opera has built its business on emulating IE (so called "IE5 bug-compatible") in mobile browsers.
So naturally, Opera would be opposed to any move by Microsoft to curb the chaos and make web pages easier to render. They couch this in terms of backward compatibility, and in fact Hakon Lie and other Opera employees event went so far as to found a new standards body to push their own agenda, and started with similarly threatened browser vendors as members. (Contrast this with the W3C, which invites both vendors and users of a technology to hammer out a standard that serves both ends of that economic stick.)
So, why support a Microsoft decision that seems so harshly standards supporting, as Joelonsoftware points out? Perhaps because a harsh position is unworkable, and perversely leads to delays in adoption of IE7 and IE8 with their new features and new implementations, thus leaving more time for Opera to milk the IE5 bug-compatible business, while they build up their new standards.
Oh, and it seems like the "backwards compatible" mantra has been dropped a bit, with all the hoopla over dropping "apparently unused" attributes such as "rel" from HTML5.
The Bush Administration's Katrina report has an appendix called what went right, with praise for Amateur Radio:
Other organizations worked tirelessly to assist emergency responders that, due to the storm, did not have the equipment and means to effectively carry out their duties. Amateur Radio Operators from both the Amateur Radio Emergency Service and the American Radio Relay League, monitored distress calls and rerouted emergency requests for assistance throughout the U.S. until messages were received by emergency response personnel.
Ham Radio works because each it's a heterogeneous mesh network of intelligent agents using agile frequency hopping to provide connectionless redundant relay of messages. Yes, we do that!
