What about the tons of dust and debris that fall to Earth every single day? What about the heat this planet radiates out, the loss of gases that occur naturally?
I was just thinking about this today, after explaining to my kids how the Earth races around the Sun (and itself), and still we can't feel it.
Hvis alt går som planlagt, vil den sidste linje du ser være OK
(Sørg for at indtaste teksten som den er – især det store P i Promethean)
I did not translate anything from the page. The last line says that you should make sure to type the text exactly as shown, including the capital P in Promethean.
Based on information from these two links, I'll try to answer your questions (my translations).
-Wifi and GSM are on different bands so why speculate cell phones could also have the same effect?
The report doesn't explain this. It goes from "We want to study the effects of radiation from cell phones" in one paragraph to "we'll be doing this by [...] cress seeds placed near Wifi hotspots or not" a bit later. The teacher notes "For newer 3G or LTE connections, the difference [compared to AP frequencies] is minimal".
-Did they repeat the experiment using the same plant seed type more than once?
They used seeds from several bags, mixed together and then divided in 12 lots.
-Did they note the temperature, humidity and sunlight available in each room at regular intervals or used any data logging equipment?
Not according to the report. From the teacher: "windows of similar size and both facing south" and "computer controlled temperature (18 deg. Celsius)".
-What kind of rooms, and were they in the same home? Were they the students bedrooms or what?
The report doesn't say. From the teacher: "Access control: only a select group of people can access the 'depotrum' used for the experiment". 'Depotrum' could mean a room used by janitors, to keep books etc.
-Were both testbeds receiving the same amount of sunlight for the same amount of time?
The report says "both windowsills [?, the lowest part of the window frame, facing into the room] were facing south, so we could ensure that all plates were receiving the same amount of sunlight". See note from teacher above.
-Did they try other plant seeds? Or buy the same plant seeds but from different vendors to compare?
No other plant seeds were tested. It is not clear from report or teacher if the bags mentioned above were from the same vendor.
-Did they try to repeat the experiment with the router off to isolate the possibility the rooms environments played a role?
The report doesn't mention this. According to the teacher, they did run the experiment twice, not to test differences between the rooms, but to test if network traffic played any role. The first run was made with the AP only announcing ESSID, the second run had the laptops pinging each other [constantly, I assume].
Could somebody please explain this voter registration system to a non-US citizen? What's the purpose? Who benefits from it?
In my country, I'm free to choose whoever I like in the voting booth on election day. I don't have to show any previous affiliation with any party. Nobody knows who I voted for last time, nobody knows who I'll vote for next time (including me).
trust them to behave, or simply don't care if they don't behave- there's still no real evidence that kids accessing say, porn, causes any actual harm anyway.
That is how it works in reality. All other "solutions" would be worse. I can remember exactly one episode from the last couple of years.
internet access should be treated the same way as it would be by a "good" parent - supervise them whilst they're using it.
This works OK in class, but what about recess? When the parent takes a break?
I teach at a high school ("gymnasium") in Denmark, and we don't monitor kids during recess. They are free to use their laptop or tablet as they like. Some even use it to do homework. We use negative site filters and block most ports.
It wouldn't make sense to turn off internet access during recess, since we often drop one break to end the module (?, 2x45 mins lessons) earlier. And if we did, the kids would use 3G or LTE, without any control.
Thanks, just bought these (PX 100-II). They are indeed very impressive for the price, $60 in Denmark, and they can be folded down to something the size of a pair of sunglasses.
Isolation isn't too bad, based on playing Depeche Mode: Violator at a realistic level (I'm 45) with the headphones placed over my thigh.
I haven't used a pair of on/over ear headphones since the first iPhone came out. What a mistake...
I do not carry such information in my mind since it is readily available in books....The value of a college education is not the learning of many facts but the training of the mind to think.

Time spent memorizing stuff is time that could be better used understanding it. Having no access to reference material is a ridiculous limitation.
The writing technique (jumping back and forth between two separate storylines) interrupts the flow in the novel. So far, it isn't as annoying as "State Of Fear" or "Prey" by Michael Crichton.
If you like this type of novels, I would recommend "The Swarm" by Frank Schätzing.
If you're after something that locks your screen and activates the screen saver, much like Windows-L does, go to Keychain Utility preferences and Show Status in Menu Bar. You'll get a little lock icon in the top right which can do that.
I've setup my PowerBook to require a password when waking up from sleep or screen saver. Then I've set (System Preferences -> Dashboard & Exposé -> Active screen corners) the lower right screen corner to start the screen saver.

This is why I keep reading slashdot. Thanks!
Pascal's Wager?
I was reminded of that when I found a video called "The Most Terrifying Video You'll Ever See" on YouTube some years back.
In the US. I come here for "News for Nerds. Stuff that Matters". Nothing particular American about that.
640k should be enough for anybody.

Is the Earth slowly gaining or losing mass?

Since I submitted the story, the full report has been made public, and the biology teacher involved in the experiment has commented on various details.

They used roline wireless routers for the experiment.
the individual professors are the most important part of a quality institution
I wonder if this guy teaches there. He is local, and he would have made me study EE instead of chemistry.
At least point to something relevant: Sorting algorithms as dances.

That is not entirely true: Mobile Device Management (MDM). I how no idea about costs.

Wouldn't it be wonderful if life on Earth originated from a similar mishap (bug science project + lost tool bag)?
I'm reading "Deception Point" by Dan Brown at the moment (currently at p. 204 in the paperback version).
Is it safe?
If the thing between the first and second digit on the second line is supposed to be a decimal, then I would have to agree.
