Power Outages Strike East Coast
fordp writes "CNN, CNBC and others are reporting that major power outages are happening just after 4:00PM EDT in New York, New Jersey, Detroit, Ottawa and Toronto, Toledo." There are reports of a Con Edison transformer on fire on 14th Street in NYC, and lots of people stuck in trains and elevators. CNN is reporting that it is, according to power officials, most likely not related to terrorism, because you know you were wondering. The Niagra Mohawk power grid is overloaded, which feeds electricity throughout the northeast U.S. and into Canada. Update: 08/14 21:06 GMT by P : The mayor said there was no fire, that it was black smoke brought on by an automatic shutdown because of the power grid failure.
..You don't have to worry as much about port 135 being open.
Some reports have suggested that Boston, MA, US was affected. Downtown is operating normally.
Given one hour to live, the student replied: "I'd spend it with professor FP who can make an hour seem like a lifetime."
If I had power I could First Post.
And in other breaking news, a great chorus of laughter could be heard clear across the country, apparently originating from California.
On a conf call with some co-workers - they started losing power intermittantly just over an hour ago.
Mayor Bloomberg was just on the radio and said that the Con Edison transformer on 14th Street in NYC is not on fire. It just release some black smoke when it shutdown due to the grid overload.
This article detailing using semiconductors to mitigate large scale grid power surges ran in today's NYTs.
I'm in Manhattan right now, near Colombus Circle. All power is out across all 5 boros. No traffic lights, hundreds of thousands trapped in the subway... I'm dialed in through Verizon (wow. good network, right?) on a laptop, through a PBX with a battery backup.
According to the radio, the 14th street power station is burning. Of course, it also is talking about blackouts from Cleveland to Toronto. With no power, my poor tropical fish have less than a few hours to live, and I already hear a crowd in the street screaming, but it's mostly good natured right now.
I'm sorry, this seems like sabotage. I've got 100 gallons of fresh water, and a sword.
And I'm posting on slashdot.
Oh well. I guess I just wanted to say hello. =p
I was watching Modern Marvels on the History channel, randomly, when I noticed that CNN and MSNBC had their news anchors put the war helmets on, and start the 9/11 rant all over again.
I'm not one to say that we shouldn't worry a little, but coincidences happen! Why should we jump to conclusions long before anything really big has happened? Come on now, this is just way too much hype!! When they begin to find evidence of something bad happening, then tell me about power outages.
People stuck in elevators? Please. The power goes out everywhere, let's at least pretend that we're not shaking in our boots, and put some confidence back in our country!
A huge power blackout hit U.S. cities spreading from New York to Cleveland and Detroit and north into Canada Thursday afternoon. In New York City, the blackout affected subways, elevators and airports, including John F. Kennedy and LaGuardia airports. Thousands of people streamed into the streets of lower Manhattan in 90-degree heat. In Toronto, Ontario, too, workers left their offices after the blackout hit shortly after 4 p.m. EDT. Traffic lights were out throughout downtown Cleveland, creating havoc at the beginning of rush hour. There were reports of outages in New Jersey and Connecticut as well. Every prison in New York state reported a loss of power and had switched to backup generators, said James Flateau, a spokesman for the state Department of Corrections.

OH THE SHAME I fell off the wagon and use sigs again!
They set up us the bomb!
We had the power brown out here in South Central Michigan, which lasted for a few minutes. Right in the middle of playing a game, fortunately I just saved. I hope this ain't hacker or terrorist related...
Taking guns away from the 99% gives the 1% 100% of the power.
Judging by this chart I'd say a whole lot of people were running their air conditioners today. Maybe that's it?
finally got that extra long extension cable rigged up....
This is kind of weird. I work at a mid size hosting center and ISP and since we normally run on generator power, we didn't know that there was a widespread power outage. Things started popping up on our monitoring system -- and they all seemed completely unrelated. Of course, it turned out that all the things going red were customers with T1 lines and such, that were in buildings losing power. :)

You know your a geek when your reading Slashdot during a power cut. :-D
He also said that there was no grid overload, it was just being shut down for regular maintenance.
...that this is due to a single fire at a major ConEd substation.
So this one isn't terrorism (so they say), but I'm sure terrorists will be delighted to know that they can throw five major cities into utter chaos by taking out one substation and getting an assist from the domino effect.
~Philly
I always wondered what that wall switch was for and today I finally turned it off. My bad. After dinner I'll go turn it back on.
So long, michael. Don't let the door hit you...
NO CARRIER
Litigious bastards
Don't believe that sunspots can trigger power outages? Think again.
Should serve as an example to the Department of Energy. The U.S. needs a distributed power generating system ASAP. Lots of small solar and wind generators all over the nation. Every block should have one.
Right now, "officials" are saying this probably isn't terrorism. But I bet it's giving al-Qaeda some ideas.
If an accident can make this happen, I'm sure a cleverly-placed explosive can make it happen much more easily.
And once all those cities are out of power and essentially crippled, the real strikes start.
And now, if you'll excuse me, I have to go get some tea on for when the FBI guys come knocking on my door. Does Ashcroft take one lump or two?

1977 Power Outage
It's still moving. Erie, PA, flickered when it happened and just went out (5:10 PM Eastern). It's on the lake between New York and Ohio, so it's on the cusp of whatever grid we have here in Pittsburgh. I think I'll go turn off my air conditioning.
R: That voice. Where have I heard that voice before? B: In about 365 other episodes. But I don't know who it is either.
I expect Bush to adress Congress tomorrow. He will tell them that the US needs to be able to provide for its own strategic electricity supply. Airco is a national security priority. Therefore Canada will be annexed by the end of the week.
Canadians that object will be labelled terrorists and put in camps where they will be working on new pipelines, new electricity lines and clearing out forrests. All others canadians will be subjected to pay the USA's debt as a thanks for now becoming part of the world's oldest democracy.

New York Official Says Power Grid Overloaded -CNN
Thu August 14, 2003 05:04 PM ET
WASHINGTON (Reuters) - A New York State official said the Niagara Mohawk power grid overloaded on Thursday, causing a massive power outage, CNN reported, and New York Major Michael Bloomberg said it was likely a natural occurrence. "It may be well into the evening before power comes back on," Bloomberg told the U.S. cable television network. He said smoke from a Consolidated Edison Inc. plant in the city was due to the plant's automatic shutdown, not to a fire, as had been reported. He said, "I can tell you 100 percent sure that there is no evidence as of this moment whatsoever of any terrorism." A massive power outage swept across swaths of the eastern United States and Canada on Thursday, leaving sections of New York, Detroit, Cleveland and Toronto without electricity, witnesses said. It was not immediately clear whether the Niagara Mohawk problem caused the wider outage.
I'm typing from 30 miles southwest of Boston. I've heard reports that Boston is affected; but here in the suburbs, we're not having any problems.
It's worth noting that, no matter what caused the initial problem: The results we're seeing are exactly what happens when the populace fails to concern itself with potential problems. We Americans, even today, suffer from a serious case of "It'll-never-happen-to-me." Experts have warned for years that our power grids had dangerous "pressure points," where small problems could cause massive failures.
Unfortunately, when we hear the phrase "potential problem," we hear the first word and never bother to listen to what follows. "If it's not a sure bet, why worry about it?" Well...here's why.

Blah.
inside this building there is a level where no elevator can go and no stair can reach. This level is filled with doors. These doors lead to many places, hidden places, but one door is special. One door leads to the source...etc... Now that the power is out we have only five minutes to find the door on that floor.
The power company obviously had Linux running and had to pull the plug because of SCO.
oh, and I blame SARS as well.
This Salon article debunks that myth that started with a blackout in New York in 1965 (see page 3).
See also the Snopes article on the 1965 NYC blackout.
If there had been some X class flares, it would be possible; but spaceweather is only showing a max of a C3 [not really bug] in the last six hours. C6 in the last 24.
With only C level flares, I really doubt it is the flares. They would have had the X level listed if it happened.
Watch what happens in the wake of this... every news program on the planet is going to talk about how "inadequate" the power system is and how we need MORE, MORE, MORE power. Nowhere will you likely hear anything in the mainstream about CONSERVATION. That's a four-letter word in the eyes of the current hyper-consuming society.
- Hot day with tons of ACs running. Check.
- The "magic smoke" being released from one or more power substations. Check.
- Instant power shutdown as a domino effect of overloaded substations occure. Check.
Really, this isn't even the first time something like this has happened at NYC (and surrounding area). A huge power outage just like this happened in 1977. Also, just a couple of years ago several STATES lost power for a short while.Let's all turn on our lights at 4:13pm.... shh... don't tell anyone

CNN just spewed the same speculative garbage.
Let's preview the baseless speculation that we'll likely hear in the next hour or so as 24-hour news pundits rush to scare the crap out of the public in their overzealous attempt to add more color to the simple news item that they intend to milk for all its worth over the next day:
* CNN interviews a taxicab driver whose cousin thinks this may be the work of Saddam Hussein
* Fox "confirms" the "terrorist attack" using as evidence, an unnamed "washington insider" noticing a dark-skinned man walking down the hallway of an unspecified building seconds prior to the outage.
* Red Cross is immediately planning "Power Aid 2003" featuring an all-new remake by Vicki Lawrence of "The Night the Lights Went Out in George" - proceeds of $100 billion are expected, $11.43 of which will actually be used to improve the power grid.
Why in the world is it engineered that way?
In the event of a large scale failure, you can have huge surges and sags in the power grid. The effect then spreads out over the grid and reaches other power stations and equipment. Those systems see it for the problem it is and automatically shutdown to avoid damage. ("Shutdown" might be a bit of a euphemism; it could be something as simple as a very large fuse blowing.) We are talking about systems with hundreds of thousands of volts and an ungodly current capacity here. It's one thing if your CRT gets hit with a surge and smokes. At a major power plant, it could be like a bomb going off. Far better to have a major outage that takes a few hours to clean up, then a cascade failure that does lasting damage everywhere.
It is also worth pointing out that Niagara Falls provides a huge amount of power to the surrounding regions. A failure there could mean a serious loss of capacity.

I do not like Microsoft. Remove them from my email address.
You bring up a valid point, but a massive blackout like this one happens because the already-loaded grids are used to supply the blacked out grid. The more grids black out, the greater the demand on the other grids, increasing their chance of failure.
Kind of like a domino effect.
The system is probably way too slow to handle (or predict?) near-by grid failures, which is why other grids are popping, too.
The mayor said there was no fire, that it was black smoke brought on by an automatic shutdown because of the power grid failure.
Actually the smoke was from the Mayor's handlers trying to spin the fire story so as not to cause panic.....
I think it would have been better for the Mayor's minister of dis-information to have done this on television with a flaming transformer in the background.

Wow! Mind boggling improbable!
Conserving power is ludicrous. There is an unlimited supply of power in the Universe. Why should we even *consider* conserving it?
We need MORE POWER NOW! I want cheaper, more reliable power. I want a nuclear plant next to my house, better yet, in my basement, for my own personal power usage.
Conserving water, makes sense, we only have so much h2O, although it'd be better to invest in purifying our current supply and recycling water.
So, again, WHY? WHY SHOULD WE CONSERVE POWER????? WHY WHY WHY????
my power bill is $180-200. I keep my house at 72-75F, even when it's 105F outside. IF the power company gets 35% more expensive here then it will be cost effective to generate my own using propane and a generator.

A power outage in August?!? It must be terrorists, since during the hottest month of the year there's no reason to use much electricity.
end sarcasm
Bush et al have got you people afraid of your own shadows. Sad, really, though still funny.
This collapse was predicted years and years ago. When I was working for a power equipment manufacturer (transformers, relays, switches, capacitors), marketing was playing this sort of thing up to the utilities.
As equipment gets old it becomes less and less efficient. This includes the transformers that bring the power from high voltages to low voltages to your home, and the generators that produce the power. AND it includes all those Air conditioners that are running in hot weather.
No-one has been able to afford to bring new generators online recently. And probably not to upgrade/replace old less efficient equipment. And I'm sure most people haven't bought new ACs either because of the economy.
It wasn't so long ago that something similar happened to Chicago during a heat wave there. And we all remember a few years ago that California had rolling blackouts because the grid couldn't handle the power. And NYC suffered similar blackouts for the same reason in the 60s and 70s I believe.
Unfortunately since its such a large grid its going to take a while for it to come back up. You have lots and lots of main power generators. Each one has to be brought back onto the grid one at a time. Each one has to be synced to the current AC 3 phase system within 5-10 degrees of what's there or when that generator comes on it might cause all the generators to drop out. Syncing a generator takes time and patience.
Then you have to bring the consumers back on. Every time you bring a new section on you have a hell of alot of inrush current as Air Conditioners and motors start up. This is why your lights dim a bit when you turn on certain pieces of equipment. Imagine the dimming you get as 1000 Air conditioners come on at once. If its too much a relay might trip off and the grid might collapse under the strain as a generator falls offline. And yes this is a real meaning to the word offline, the generator is not on the power lines anymore.
It will take time for everything to come back up, and con-ed isn't going to rush it. They will take it up in stages, make sure that everything is ready to go before bringing up the next stage. A collapse this large can happen again and again if they rush. But it might be quicker, the reports don't saay how big the failure was and how many generators fell offline. It could just be that all the distribution substations tripped, but I doubt it. For this to be so widespread the generator protection relays probably all fired off and took their generators off the power grid.
Don't you just love cascading failures? Overloaded power grid; all the generators are close to their shut off point. One fails, all generators go into the range of shutoff, and off they go one right after the other. They probably all fell offline withing 30 seconds, and will probably take 3 days to come back on fully.

There is also the Enron factor. A couple of years back when Cheney gave Enron the green light to manipulate the California energy market California was making deals to buy any capacity it could
During the period the market was being manipulated the cover story was that it was California's fault for not allowing new plants to be built. Power plants have a major lead time so the only way to get generator sets for new power plants to be built in the West was for NYC to give up the generator sets for a bunch of gas turnbine systems planned to be deployed in the East.
Thank Bush, Cheney and their big friend 'Kenny boy' Lay for putting the interests of Enron before the national interest. First they screwed California and now NYC may well be getting hit by the unexpected results.

Reporter Shepard Smith at JFK airport said over the Fox News network that airport maitainance workers were delayed in fixing the generator because they were initially denied access to it because they could not be cleared to access the generators without the metal detectors being powered.
I've read that the stability of large power grids is still a poorly understood problem. Normally they are reliable, but what happens when they are already running close to the limit of safe operation and a major generating facility goes off line?

I know it sounds strange, but I'm sort of sorry that I'm not in New York for this (I moved to Boston 25 years ago). Yes, I know that it's a monstrous pain in the ass for everyone and even has the potential for injury and loss of life (e.g., heart attack from climbing stairs), but both blackouts I've been in ('65 and '77) were interesting experiences.
I was five years old for the first one and scared out of my wits when the lights went out. It was an early evening in November, around 5:30 PM, and I was sitting on the kitchen floor, watching TV (the Winchell-Mahoney hour). Lights, television, even the streetlamps outside went out. My first thought: "Mommmmmmmmm!!!!!".
We ended up walking over to my aunt's house a couple of blocks away and eating the cake that my mother had baked that day. That was our dinner. Blackout cake. She never made it again after that, but I remember with all the flickering candles it seemed like someone's birthday.
My father got stuck on the subway for 36 hours, though. Bummer for him.
When the '77 blackout hit, I was living with my father on the 15th floor of a building on East 96th St. I'd just gotten home from my summer job and turned on the radio. The DJ was complaining about the turntables running too fast (overcompensating for low voltage?). Looking out my bedroom window, I saw the blackout roll uptown: the Empire State Building went out first, then the rest of Midtown, the Upper East Side, and then us. It was a hot, humid night and you could see the occasional flash of heat lightning.
I checked on my neighbors, an elderly couple, before heading down to the street, where I bartered a couple of cold beers for a handful of candles. People were bewildered, wondering if the Indian Point nuclear plant had blown, or if the Rooskies were attacking. It took about an hour for the looting to start north of us and for most of the night there was an endless parade of NYPD patrol cars headed uptown, four or five cops in each, all in full riot gear.
I don't want to downplay the millions of dollars of damage that happened that night, but my neighborhood was pretty peaceful. It was like an instant block party, people sharing food and beer and the occasional joint, oldtimers (I guess that's me now) talking about the '65 Blackout (which, like today, started at the Mohawk grid and covered roughly the same area).
Fifteen flights up was nothing for me back then; I ran track in high school.
A couple of years ago my neighborhood in Boston lost power for 36 hours. Nothing big, maybe 25,000 households, but I was bereft. No cable, no Internet, just a battery-operated radio and, of course, candles. Off the grid.
But it was educational. I never realized how dependent I was on technology and the network, how much of my time is spent in front of the silicon devils (TV and computer). Thirty hours with nothing but books and an acoustic guitar for entertainment. When the power came on, the first thing I did was fire up a web browser. It was like a refreshingly cool shower of meaningless information after having to sit and stew with my thoughts.
Shit. I think I'll go to the basement and throw the main breaker. Just for old time's sake.

There are three kinds of people in this world: those that can count and those that can't
1) Generators run their units with minimal loads
to keep in sync, so that when it's
time to ramp up, sync is not an issue.
Mostly true.
Gas turbine plants are made for peaking, and can supply whatever is demanded within a second or two- but their capacity is limited.
Many of the baseline load plants, steam plants, take sometime to change power output. Nuclear power plants are the worst.
I just started working at a nuclear powerplant, so my understanding may not be fully up to speed, but here's what I know so far:
When our plant is disconnected from the grid (not easy, because we have three lines running out on seperated paths, but it happened last year), we have a whole lot of energy in the system, and no place to put it- so we trip the plant. that basically means that the control rods drop into the core within seconds of being disconnected from the grid, and the plant starts to cool down.
We have in-house diesels to safely shut down the plant with, but they can't put out the voltage or power required to run the largest motors in the plant, which are needed to start power generation back up. Essentially, we need to be connected to the grid to start and run the plant.
These large motors, combined with everything else, use up about 3% of our plant capacity. I don't think we can run at 3% capacity, but I'm not positive. Basically, even if we knew ahead of time we where to be disconnected, I don't think we could ramp down the plant far enough to run only house loads off the main generator.
Short version:
1) A nuclear power plant can't start or run without being connected to the grid.
2) Once connected, they take about a day to get up to full power output.
3) Nuke power plants are typically a grid baseline load- meaning they're the last to have to cut production in the face of reduced demand. Nuke plants account for 20% of our electrical consumption.
2) The grid doesn't have to be brought up with
all generators and exchanges linked, they
can be brought up as islands and rejoined later.
4) Generators can only keep in sync when the grid is there to sync to. If the grid is disconnected, one plant starts, and everyone syncs to that. But I don't believe it takes very long to sync, maybe minutes. Though it is possible that if it's only one plant per 'island' they could drag the sync back to match with other islands.
That's all based on the assumption that other plants work roughly the same as Seabrook Station in Seabrook, NH. I do not claim authorative knowledge.

Real Iraqi Information Minister QuotesI thought the "grid" was, basically, composed of consumers and producers of energy. I know that there is a balancing act between supply, demand, and the requirement to balance the loads within line segments, but it was my understanding that as long as there were consumers for your energy then you could generate it.
That's an oversimplification, I know. But I don't understand this case: A major power producer goes offline, but the consumers don't. Why can't the remaining producers take up at least some of the slack?
www.howstuffworks.com might have some good information, but I don't have any direct links.
The grid is composed of three parts: producers, transmission, and consumers.
Now when a major plant goes offline, typically other plants do take up the slack, so you've got the right idea. For example, in October, Seabrook station will go offline for refueling, and no one will notice, because we're paying other plants to generate the electricity we committed to. The excess peaking capacity of the grid goes down, so there's a smaller margin for peaks, but brownouts are largely avoided.
Now in comes the transmitters: It's often referred to as 'The national electric grid' but that's not quite correct. The system is capable of transmitting power from Maine to California, and Florida to Toronto, but there's a lot of sub-grids with sometimes minor connections between them, and these are typically open- there might be a small connection for keeping sync, so they can close on demand.
Each inter-grid connection can only carry so much current- the lines would heat up and start to sag, substations would catch on fire, that sort of thing. This can't really be tolerated, so when a connection's capacity is overloaded, the breakers pop open and the 'donor' grid just gives a big 'fuck off' to the recieving grid.
So when this happens, it starts to ask even more of the other grids it's connected to, increasing the chance that it will cause an overcurrent trip on these other lines.
These connections can also be manually opened and closed by the grid controllers- in NH, the control room is in manchester, and I think it's run by a company called ISO. An overcurrent trip may require a lineman to visit the substation in question, i'm not sure.
Now, every plant except nuke plants runs lower than it's actual capacity to keep some peak demand reserve, so in general, they can pick up the slack when one goes down. Each powerplant does have it's limit, though. If demand on a particular plant exceeds it's capacity, the voltage will drop, and the plant will likely trip on undervoltage, or a grid connection might trip, or the plant operators might shut the plant down to preserve the equipment. (Most things in my powerplant like to run at one-steady state speed. Since voltage is proportional to speed, lower voltage means the main generator and turbine slow down. I won't go into the details, but suffice it to say, it's no fun)
Shutting down one plant will of course increase demand on other plants. So I'm sure you can see by now that once a cascade starts, things can really start to go to shit.
This is ideally avoided by having ridiculously over-rated transmission lines, and grid excess generation capacity well above the output of any one or two or three plants. However, I don't think we've really beefed up our transmission lines since the 70's or 80's, and new powerplants are often stalled or killed by NIMBY's and groups like greenpeace who haven't the slightest clue how a nuke plant works, how it's different from a bomb, and how many robust safety systems there are between the radiation and the public.
We've been setting ourselves up for problems for sometime now. It's time to build new power plants, and beef up transmission lines, cause demand sure as hell won't recede.
Corrections to my statements are welcomed from people with more than my meager two months in the power industry.
**Nuke plants typically run at full power
Alcohol, Tobacco and Firearms should be the name of a store, not a government agency.
Maybe my wording was unclear- Nuke plants do produce about 20% of the power we consume.
m
There are only 104 nuclear powerplants in the US, you're right on that.
However, These plants have 1-3 reactors at each site, each producing roughly a gigawatt of electricity- enough for a million homes.
So you've got at a minimum, 150 gigawatts output of just these 100 powerplants. Take your electricity bill, and figure out your average hourly kilowatt usage. Now divide 150 GW by your average consumption.
Do you still think I'm wrong? Or does it kinda look like nuclear power could run every home in the United states by itself? (Of course, if we wanted to run businesses and industry, we'd have to bring all the other plants back on.)

Seabrook is where I work, and How stuff works says 15% for the US, the US department of energy says 18.6%, both of which are close enough to the 20% I stated.
Alcohol, Tobacco and Firearms should be the name of a store, not a government agency.
Every normal shutdown procedure should come complete with billowing clouds of black oily smoke.
Nothing to see here, move along.
Intolerance for ambiguity is the mark of the authoritarian personality.
From what I've seen on TV coverage, they showed the source of the black smoke. Looked to me like a refinery or something with the safety flare-off stacks burning. I live in the heart of petrochemical alley down along the southern Mississippi River, and believe me, whenever there is a widespread power failure, they all do the same thing.
There are many stages to the processes that turn oil into gasoline, plastics, and other petrochemical products. Whenever there is an upset to the process, such as a power failure, complex systems (on backup power, of course) are designed to shut down the plant in a controlled manner to prevent a catastrophe, and many times that involves venting unprocessed flammables to safety flare-offs to be burned off.
About 7 years ago, a transformer failed at a major substation over by where I live, plunging a large area into darkness. Within seconds, a series of loud explosions were heard at a nearby plastics plant. People living in the area were panicking because they thought that the plant blew up, but the TV and radio newscasters calmly explained (to those who could recieve the broadcasts) that it was part of the safety shutdown procedure, that the loud booms were caused by safety pop-off valves and what looked like burning Iraqi oil wells was the safety flare-off stacks burning.
thanks for the insight into different gun "groups" or "cultures" in the US.
Okay...I'm curious. Why would cut down anyone "who's head stick up too
good question!
Rosey Golds, a social commentator for ABC radio (Australian Broadcasting Commission) says:
"The tall poppy syndrome expressed our great reluctance to defer to authority figures (and thus establish a new class system) and our abhorrence towards a society predicated on the worship of money. We mocked the desire to impress. There was a great Australian proverb used to describe the wealthy graziers who came down from the country on holiday breaks flaunting their Akubras - the wider the brim the smaller the property "
We do it because of our background. We are by nature very cynical of authority figures. Many friends of mine in the USA think they are cynical of their political figures...but they haven't seen Australian cynicism. We often give our pollies no respect at all.
A certain amount if cynicism is good. But not too much. Another advantage of our "tall poppy syndrome" is that we treat people based on their substance...IE who they are...not how big a car they drive, what title they have, or other such social standings. In social interaction, we very rarely introduce ourselves with titles (IE Doctor, Professor, Coach, Reverend etc etc). Nor do use those titles (An exeption would be a doctor of medicine, but we would only call them doctor whilst at the hospital. At the pub we would call them Bruce). I was amazed once when visiting the states with my parents (My mum is a General Practicioner...ie a Doc). When shoping in a department store, people would call us "Sir" or "Maam" (Which is weird for us!). But when they saw Mum's credit card with "Dr" on their...we all of a sudden would get red carpet treament. Sales assistants would be there ready to help, calling her "Doctor". It was very strange, unheard of to get better treament because of your profession in Australia. When Dad visits the USA (or has colleauges visit him), every American calls him "Doctor" (He's got a PHD). I've never seen it happen here.
With all cultural things, there are often reasons why things happen that way...but as always too much can be very bad.
Sites you may find interesting is
this one. I found it using google, so haven't read it before (and thus may not agee exactly with what it says).

I am STILL in my rackspace. I was here when all the overhead lights went out.
First reaction: I see happy LEDs, whew.
Second Reaction: when the overhead lights came back on seconds later, you see 10 techs looking at their hands as if the ethernet cables they plugged in caused the problem! Funny.
This is the most comfortable place in Manhattan right now. Sleeping here on Sun cartons and bubble wrap in the AC due to zero transport home to CT.
Verio's got all generators working, and should weather this. For this I am eternally grateful. Let's take a moment to praise the folks who plan for this kind of problem in our data centers!
A few major reasons. First and foremost, the Constitution was thought to be a document to goveron the nation for, at most, a generation or so. After that it would be scrapped, and rewritten as more appropiate to the times, (although I would be hard pressed to find something I like better). The Founding Fathers were concerned that THEY not some future despot would become drunk with power and try to oppress the people. Remember that we were less than ten years from a fairly bloody conflict with our (and your) parent nation.
The theory was that the people should have the ability (not necessarily the right) to overthrow the government, should it become necessary. Indeed history shows us that in most cases despots have first disarmed the populace:
The Founding Fathers had some very specific viewpoints about it as well.
There was legitimate fear that the government would become corrupt, and NEED to be overthrown because the people would be unable to remove the corrupt from power.
From our Declaration of Independence:
This is a small section of the document that many Americans actually feel is more important than the constitution. After all, there are several perfectly legitimate ways to organize a government. Furthermore, a constitution needs to change with the times.
Over the years how we have interpeted and taken this portion of the Declaration has changed. Now, we a
There is a civil war coming in the United States. Remember which side has most of the guns
