Two of the sensors are used to detect low levels of liquid hydrogen propellent, the other two low levels of liquid oxygen. The sensors are used to make sure that the main shuttle engines shut down properly prior to the sudden loss of fuel.
The sensors are also most likely placed at key points, where the liquid oxygen and hydrogen feeds into the TWO main engines. Each engine has to be supplied with each propellent, and the sensors are designed to protect each engine. Two propellents per engine for two engines equals FOUR SENSORS
Accessing this area is difficult, and NASA is very unlikely to launch with a faulty sensor. Especially when they had this same sensor anomally appear on a previous fill test, BUT WERE UNABLE TO DUPLICATE THE PROBLEM. NASA swapped parts and continued with the scheduled launch after another fill test FAILED to reproduce this sensor anamoly. After today they will be looking very closely at this.
Their launch window ends July 31st. We'll find out today before 5pm EST what they are planning on doing.
How do you get cell phone reception? When I went to school there nothing reached us. The ambulance company had "first responders" that they issued pagers and radios to and even those barely worked outside of the city.
Ah, but the state is making Bellsouth do this. For those of you that aren't from Louisiana (or any other similar region) Bellsouth provides phone and broadband service only. However, if they made Cox Communications do it, they provide phone, cable and internet. But even then, corporations would still be griping about the cost and Cox would probably raise the rates for the rest of the state. (Anyone notice how much cable costs down here now)
There are added advantages to land lines over cell towers. Granted cell phones have added mobility, but you get hit with overage charges and service contracts. Land lines (once they're installed) the service is cheaper, you can have broadband (at a much cheaper rate than wireless broadband) and during bad weather, provided your lines are underground, you still have good service. Also, living in Louisiana, there are certain are very difficult to get good coverage, whether it be land or wireless, just because of the geography and the sparse population.
From what Miss LeGuin has said of her publishing contracts she has a slightly better deal then current writers get today. Her publishing houses picked her up before they really had any credit to their name so she probably didn't get quite a screwed. She may have signed publishing rights away but you don't neccessarily sign away ALL your rights to a book to get them published. Especially the potential film rights.
One would hope that they would figure out that a a good portion of their audience has a functional brain and would like it stimulated with quality programming. But they probably won't. The really frightening thing is that there are all of us that want good quality programming but somehow really bad stupid and pointless shows like Scare Tactics get even better ratings. Now explain to me why they couldn't afford a fifth season of Farscape but they could have shows like Scare Tactics?
You shouldn't wait up to 24 hours to report a missing person. However, the television shows aren't entirely off base. Obviously, if a child is missing, its an immediate response. But, in a lot of areas you cannot officially report an adult missing until 24 to 48 hours after you last heard from them. Sometimes this policy varies depending on your relationship to the missing adult. Every city I've lived in has had a different policy for reporting missing persons. I haven't working the law enforcement end, but from the evidence collection side, the earlier the person is reported missing the more likely they will be found. The more likely we will find evidence of their presence, potential foul play etc.
Good point, cell phones are allowed on every other form of public transportation. However, even on those systems you get stuck next to people talking on their phones having mondane conversations, talking a little to loudly or just being annoying. Now imagine that in the context of flying, which tends to do strange things to people. Yes the roar of the engines (another excellent point I might add) drowns out conversations from further regions of the plane, provided that the entire plane isn't talking on the phone, however picture this. You are in coach, stuck in a seat that is to small for you, your legs (even though you aren't extraordinarily tall) are almost hitting the seat infront of you, and although you aren't a large person the seat is barely wide enough for you. Then the person in the seat infront of you decides to move his or her seat back, into your knees. And you are stuck like this from Hartford to San Francisco. This would be uncomfortable enough, but imagine it if you had to listen to the person next to you gabbing the whole way on a cell phone preventing you from trying to grab a little shut eye, read, relax, work.. or whatever you do on the plane to forget about the uncomofortable surroundings you are stuck in. Those five or six hours would be miserable.
Now granted, given the wonders of this country they will probably charge an arm and a leg for using a cell phone in an airplane so it will end up costing as much as an airphone, so no one may use them. And I can see how it would be convenient to make calls, either for work or just to make the time pass more quickly, while stuck on a plane, especially cross country or international flights. Makes the idea of having cell phone free seating or its opposite very appealing.
While yes similar tremors were reported in Canada, to my knowledge this is the first time that we've ever seen them on the San Andreas.
I grew up in the Bay Area and was there for the 89 quake. With the San Andreas, everytime scientists find something that correlates with detectable earthquakes, it doesn't pan out.
So the fact that the tremors were reported in Canada AND now they are being seen in San Andreas AND correlating to detectable earthquakes is very promising.
What most people, even people in the Bay Area (who really should pay more attention to the models) don't realize is that if a big earthquake hits, its the composition of the ground thats against us, especially in San Francisco.
We could have a really high fatality rate from just the quake let alone the aftermath, which is where most of the deaths were in 1909. Not to mention the fact that after 1909 city leaders were in such a rush to make it look like nothing happened that they lowered the building code instead of improving it, so it took a while before buildings were designed to hold up to an earthquake.
If you look at the journal that this was published in, it wasn't published by mass market media. It was published by the American Association for the Advancement of Science. It is unfair to say that the "media" should have looked outside of "our" country before documenting "something other than the injustices in Irag." Science is a peer reviewed journal which means that the actual scientists doing the research write an article about their research when its ready to be published and submit it to a journal. That journal then sends it to other knowledgable scientists in that field to review what the researchers wrote to make sure its valid and not off the deep end and they backed up their work. If everythings okay, it goes to press. So the "media" didn't write anything.
I can't see the article yet because its only online and I don't have access until its been printed. However, when my chemistry research got published all the relevent previous research was cited so I would bet that any similar tremors would be reported unless the Canadian tremors are actually different from these.
You are obviously an intelligent person, you know a lot about geological activity. I would suggest that you not be so quick to judge everyone based on the country at which they're from. If you had actually tried to look at the article, you would have seen that it was a scientific peer reviewed article in a respected journal.
I'm a chemist and a student affiliate ACS. I personally think its a bit picky to be suing over this. But this is the day of suing over every last detail. Also, if you don't evenly protect your "rights" over a product then when you do end up in court over it, the fact you didn't go to court in the past but could have could be used against you. Which is just as ridiculous. Damned if you do, damned if you don't.
1. ACS WONT lose big time in paid subscriptions. I'm not saying that the google service doesn't have a place. SciFinder Scholar is very expensive so my university shares three portals with several others. If three people are already on the program I can't log on, and I have to be on my university's campus for it to work.
Google Scholar, although it doesn't search all of the same journals, would allow me to at least do some preliminary work from off campus, or while traveling. Then, I can repeat the search when I'm on campus using SciFinder. One of the major drawbacks is that Google Scholar doesn't provide full text to ACS journals or some of the other major science journals.
The reason why SciFinder Scholar is so expensive is that it allows us to search by so many WONDERFUL methods, that Google Scholar can't offer. With SciFinder, I can draw the chemical structure of the compound I'm interested in and then look for articles that talk about that compound, or search for reactions using that compound, find companies that sell that compound, find out all the chemical information from alternative names to formula weights. Why is this important? Naming the molecules I work with is so difficult and time consuming that its great having SciFinder to just draw the structure and find the compound, and it gives us all the known names. Google Scholar can't do that. The problem is, in order to do this, someone with a chemistry degree has to sort through every page that every journal issues every month (think about how large of a task that is) and enter all the chemical information, the structures, and the keywords. While no doubt modern search capabilities could improve the speed and lower the cost of this process, there is no good way to index chemical structures, that has to be done by a trained person.
I may use Google Scholar, but it will never replace SciFinder Scholar. I would scream Bloody Murder the day my university tried to get rid of its subscription.
2. As a published author in a peer reviewed journal let me explain something. While they can provide access to every link to my article in the public domain they can't actually provide the article without infringing on the rights of the publisher. And if my article isn't available in full text I can't get them to add it, because of that copyright issue.
3. ACS doesn't own the word "Scholar," the point they are trying to argue is the similarity in the services Google Scholar claims to provide to what SciFinder Scholar provides. Also, why do you think Google chose the word, because it would make people think of SciFinder.
4. No I don't think ACS is scared shitless, while SciFinder Scholar may be what they are suing Google about, its actually not where the money lies. The database takes a lot of money to maintain, which is why its so incredibly expensive that schools have to pool their resources to afford a product marketed to schools. However, there is another product thats just plain SciFinder, that has even more search and sorting capabilities then the Scholar version that costs A LOT more then the academic version does. They sell this version to all the corporations, thats where the real money is. While Google Scholar may be nice and convenient, if even I'm hopelessly attached to SciFinder this early in my carreer then there is no way those corporations are going to give up their subscriptions to an inferior product.
5. I think ACS is just trying to follow the trend of oh say, Gallo wineries who sued other people with the same last name or an art gallery (Gallo means rooster in I think Spanish, and the logo

How many thousands of people drive over the Golden Gate Bridge every day? And I lived through the 1989 earthquake, and that one DIDNT fall down.
