The travel-time tables/graph is a function of propagation time versus great circle distance from the epicenter to the seismic station. On a graph, this represents two lines for the P and S waves. As P and S waves travel at different speeds, these two lines on the graph are not parallel. In fact, the time differential between the propagation times of the P and waves increases with increasing distance.
Hence, if one measures the difference between the time of the P and S waves, one gets an unique value for the the distance.
Keep in mind that one needs multiple (at least three) observations at different seismic stations to do this.
Try this visualization. Suppose there was an earthquake that was recorded at the North Pole. The S-P travel-time differential indicates that the earthquake was 20 degrees away. Take a globe and look at the 70 degree North line of latitude. One does not know what the longitude of the event.
Now suppose another seismic station recorded the event and the S-P time indicates that the event was 90 degrees away. Take your globe and rotate the globe so that the location of this seismic station is the new north pole. With this new orientation, visualize the orientation of the new equator. Now look where this new equator intersects the original 70 degree line of latitude.
You should notice that there are two points of intersection. A third observation will likely break this ambiguity between the two points.
The problem is a bit more complicated if one just have either the P or S wave arrival times at multiple stations. However, it still comes down to a problem of solving an set of X unknowns given at least X observations. In a somewhat simplistic way, this is like something like
where b is the latitude of the seismic station, c the longitude, a the origin time, and number on the left being the observed arrival time. With more observations than parameters, the solution to this problem is one the minimizes the errors in matching the solving this.
The establishment of travel-time curves for a variety of seismic waves was empirical. There was no knowledge of the chemical composition of the earth required to generate these curves/tables. The travel-times were then used to construct the seismic velocity profile of the Earth assuming radial symmetry (i.e., depth dependent).
Note that it took many, many observations to establish these empirical travel-times. But how was this done in the first place?
Well, where would you put seismometers? Yup, in areas where there are earthquakes. The close proximity of these instrumentation means that one can establish a decent guess of the origin time as the earthquake was really close. Suppose the earthquake was 50 km away. The propagation time for this event would be only about 8 seconds. IOW, even if you neglected the propagation time, your estimate of the origin time would be no worse than 8 seconds off. Additionally, the estimated epicenter position would be relatively accurate even if you assumed that the event took place right under your instrument.
More distant observatories can then use these guesses of the origin time and epicenter to compute their travel-times. Do this for a bunch of earthquakes, compile these information from a variety of seismic stations, plot the dots on graph, and connect the dots.
Now use this estimated travel-time tables to compute the epicenters and origin times of other earthquakes. Then compute the errors and make refinements to the travel-time curves that lower the errors.
There are four basic unknown parameters associated with an earthquake; origin time, latitude, longitude, and depth. To solve for four unknowns, one needs four independent observations.
What is measured at a particular seismic station is the arrival time of a particular seismic wave (e.g., P- or S-wave). As you mentioned, the S-P differential arrival times can also be used and is used. In practice, the arrival time is simply
t = origin time + propagation time + focus depth correction
The propagation time is a function of the latitude and longitude of the earthquake's epicenter in relationship to the position of the observational location. Side note: an epicenter is the latitude/longitude position of an earthquake, the focus includes the depth information. If one is solving for the earthquake focus, one needs four independent observations. If one is solving for the epicenter (no depth parameter), one needs three independent observations.
So-called hot spots (fixed volcanic positions) was first proposed by the great Canadian geophysist J. Tuzo Wilson almost 40 years ago.
The mantle plume origin of these hot spots was proposed by W. Jason Morgan (as mentioned in the Princeton link). Morgan also the put forth the first model for global plate tectonics on a sphere (spring AGU meeting, 1967). This extended the work of Wilson that looked only at transform faults.
I've known Jason for 25 years and can truly say that he is one of the nicest guy you could ever meet. He is also an incredible smart scientist.
Ironically, this/. story is posted on the first day of the fall AGU (American Geophysical Union) meeting. I'm quite sure that there will be discussions and debate about this.
Seismic tomography has been around for over two decades. Global body-wave seismic tomography has been performed primarily since the 1990's. I did seismic tomography work about twenty years ago albeit using surface waves covering only a portion of the Earth.
I hope that they publish a resolution map of their inversion model. An error map would also be good. Many times only the final model is presented.
I have to agree with you that you must try to make things enjoyable and interesting. Enjoying the throng is the key thing as you mentioned. But how do you do this
Holiday shopping is a great time for people watching. I really like watching parents with children. When stuck in a long check out lin take the time to observe your surroundings. Talk to someone in line!
We have become cynical and jadded in our older age. To really "enjoy" shopping during this time one must watch the kids and try to remember when you once enjoyed this experience.
Good points but you forgot dividend payments to the share holders. Dividends helps to keep the stock price up and nice to those that want a blue chip stock.
IMHO, Microsoft hordes their money so that they can buy out companies that actually innovate. We hopefully all know the list. Microsoft is giving out dividends. Does this mean that they are no longer a growth stock?
We're going to upgrade a bunch of computers at work. For what we do we have a schizo set of OS's and applications (a lot home grown). For me, I've settled for MacOS X as I can run my X11 and Motif based programs, MS Office suite, Adobe suite, OpenGL and Apple apps on one platform.
I also need web browsing, e-mail, video, PostScript editing (I use the GPL set of apps in the GMT package), images (via Gimp and Photoshop), word processing (MS Word, Open Office sometimes has problems with files that I need to work on), edit capabilities in PDF files, PowerPoint, Excel, and somethings that I cannot think of right now.
I helped introduce Linux into my workplace. I first started with MkLinux and RedHat 5.x. I was first introduced to/. during this time in my AC days.
I need to convince the powers to be that the best use of $$'s would be to get a G5 PowerMac; I can do all my work on one platform. The powers to be hate Mac's for no logical reason except that they historically hate some people, that are no longer with our group, that supported Macs.
I think that I'll get my G5 because cost will not be an issue. Either get me two computers or one Mac to do all the things that I need to do. The powers to be also have a hard-on for some of the latest technologies. SATA, USB2.0 (high speed), PCI-X, 1394, etc... I got my three button mouse ready (actually a five button mouse) for my X11 apps.
The Washington Post ran an article about some electronic voting machines being deployed in Virginia and Maryland. In Fairfax County (where I live), we will be using the AVS WINvote system, while those in Maryland will be using ones from Diebold. Interestingly, Fairfax County is the home of a lot of high-tech companies and their employees who should be somewhat computer savy.
The W in WINvote stands for Wireless as in 802.11b (i.e., WEP encryption). However, from what I have read, there is additional encryption used and the machines normally do not communicate with another system except during setup and the final vote tally. The votes are supposed to be redundantly stored on each system.
It should be interesting to watch the voter's reactions after learning more about WINvote. A limited test of the system last year apparently yielded favorable responses.
But to the average/. person, theory sounds a lot more definitive!:-) To an engineer, putting forth a hypothesis may not be the best thing to say.
To keep this OT, SCOX is thinking that they are putting forth a theory while they are really putting forth a fantasy. In the scientific world, sometimes fantasy and hypothesis are close depending on the degree of, um, medication required?
If IBM wins this case, it sends the very, very strong message that Linux is viable, legal, and has one very big ass supporter. As SCOX has given up on Linux, their losing this case will actually supports the Linux, IMHO.
But your point is well taken and the bigger scheme of things. What do the backers of SCOX want? My opinion is that want to drag out this legal matter for as long as possible.
BTW, the appropriate term to use is hypothesis, not theory.:-) Sorry, I'm a scientist and this distinction got hammered into my feeble brain a long time ago.
One interesting thing (at least to me) is that AFAIK, the GPL has never been fully tested and look at in the court of law. In most cases that I'm aware of, the threat of litigation concerning violations of the GPL has been enough to gain compliance.
Obviously, this is not currently the case with SCOX.
The courts can be somewhat unpredictable and hence, one would want good legal help (i.e., $$$$). Of course, $$$$ could not save Microsoft entirely during their last anti-trust case. Howeverr, I believe that speaks to the "weakness" of Microsoft's position.
In this case, the question may become one of how well can the EFF defend the GPL. I don't think that this will matter much. For in this matter, you will have the full force of IBM's legal machine and $$$$ bearing down in defense of the GPL. I'm quite sure that IBM can bring a lot more assets to the table than anybody in the OSS/GNU/GPL community.
The key thing is to monitor when things go active on the Juan de Fuca Ridge; this is a mid-ocean ridge spreading center. These spreading centers are a component of plate tectonics. It would also be nice to study the precursors to the advent of volcanic and tectonic (e.g., faulting) events.
Ironically (considering your comment about military applications), NOAA-PMEL first started monitoring the JDF Ridge using data from the US military's SOSUS arrays. SOSUS is the Navy's underwater acoustic monitoring system.
I have to respectfully disagree with you. A few years ago (since at least 1998) the biggest source of topics, at that time, concerning Microsoft revolved around the anti-trust case. These stories generated a lot (relative number) of comments akin to that now generated by stories about SCO.
However, you are correct in pointing out that Microsoft stories generate a lot of comments relative to Linux stories. Then again, this is to be expected. Many of us here are fairly opinionated, and a us versus them story generates more responses.
Windows 2000 Embedded. They alluded to the schedule concerning this product during the release of Windows 2000, then dropped this in favor of the development of the embedded version of "Whistler", aka XP.
I raise this issue because we just got a HP815mfp Plotter/Scanner at work. The weird thing is that the scanner unit is operated by a self-contained computer/touch screen unit (kind of "cute") that has the requisite Microsoft OS label attached to it. It describes the OS as Windows 2000 Embedded, but Microsoft dropped the development of this! Finally, the OS appears to be Windows 2000.
Strange. I've been hanging around/. before the days when you could log in and had a user id. This was before Andover and VA Linux. If anything, the/. crew has been relatively consistent when it comes to bashing Microsoft. They have also been relatively consistent when to comes down to bashing other "evil" group and companies.
There is of course one notable exception. That pertains to a particular fruit company. Then again, that fruit company switched their OS to one based on UNIX.
I wonder if the Apple stores would give a government employee a copy if I buy it on-line at an Apple store as jo_ham has mentioned with regard to education discounts.
One thing that I haven't figured out is the full extent of the Apple government employee on-line store. From the Federal employee terms of agreement. I've added some bold text to highlight some of my questions.
The Federal Government Employee Purchase Program (EPP) is a benefit provided by Apple Computer, Inc. ("Apple"), to employees and contractors of selected agencies.
Personal Discount: You may purchase or "sponsor" up to six system bundles each calendar year (January 1-December 31). "Sponsoring" means placing an order for a family member or friend. No more than two systems or monitors may be shipped each calendar year to the same individual or entity (i.e., company, institution, club or group), whether that purchase is sponsored solely by you or, also, by other eligible employees.
Which are the selected agencies? Does this "selected" provision apply to the both employees and contractors of the selected agencies or only to the contractors?
Six systems? Yikes. Free shipping but one has to pay state taxes. Hardware discount is about 10%. This makes the deal comparable to getting a bundled deal from other on-line stores. However, buying from Apple should get one better "karma" in case somethings goes wrong.
I can do this for a Friend?:-) This is best with regard to Apple software which is available for a 50% discount. Finally, I can have this shipped to another location?
I would have to guess that you probably do not even have a CompUSA on the Big Island.:-) Or, in the local lingo: Naaah, I bet you no stay have one CompUSA on Big Island.
I'm a local boy (originally, Wahiawa) working on the East Coast.
I am older than the average/. reader/poster. In my very youthful years I protested against the war in Vietnam. I participated in a march to my state's captital to protest cuts in funding for my university. I've sent a few letters to the editors of the Washington Post; one abridged version got published. Hey, the World Series is taking place; I've sent a letter to the NL baseball commissioner about something that Marge Schott did. I've been on the National Board of a civil rights organization.
I have never done civil disobidience. I can't read the details of what they are doing because of their servers are going poof. Additionally, I have not been active in these types of activity with regard to computer/technical related issues. Many of you do a much better job than I could ever do.
I'm rambling on right now so what is my point? Get involved in social issues (and protests when needed), in a manner that you are comfortable with.
While I'm more liberal and libertarian than the norm, my advice also applies to those that are more conservative than me.
I've also mention that great site here. I changed my power supply (Antec True Power), cooling fans (Panaflow and Papst), and heat-sinks (Thermalright) based on the information provided. I also decided to get the Seagate HD's in other systems.
Once one gets a relatively quiet system, one does not want to go back to a noisy one. BTW, the biggest source of noise for me tends to be the CPU cooling fan on the heat sink, YMMV.
Speaking of text books, I knew that I was in big trouble when I got to grad school. In my first semester, the applied math prof (continuum mechanics) somewhat scornfully stated:
"There is no text book for this class. The things that I'm going to teach cannot be found in a text book."
Well, some of the things that he taught could be found in a book, but usually in a much different form (derivation) than how he taught it. Almost failed the class but I pulled a miracle in the final exam, which was worth 80% of our final grade (we had no mid-term exams, just homework).
Perhaps your original question is different than mine. This thread has woven its way thru several various routes.
I would like to debate many of you points with you, but I need to go to sleep right now.
However, I still would like to emphasize my original point about the ACLU; they protect individual rights. I must admit that there is a big gray area with regard to the definition of an individual.
Take care. We may disagree, but at least you have been civil.
The ACLU supports the free-exercise of religion with big exceptions for kinds of free-exercise they don't support. But not all the time - sometimes they weasel out of it.
Please elaborate on this, I say this not in a negative way. Kinds of free-exercise? I'm not sure what this means.
You didn't write versue (I did with my great typing skills:-)), however your use of but indicated to me a conflict.
That was my point.:-) There is no contradiction when it comes down to civil liberties. The AC/troll that I responded to was trying to point out that the ACLU does not do this.
The ACLU supports the free-exercise of religion by individuals. They don't support the government influence in the establishment, endorsement, or support of a religion.
I'm not clear about your point about free speach versue free association.

Please elaborate on this, I say this not in a negative way. Kinds of free-exercise? I'm not sure what this means.
You didn't write versue (I did with my great typing skills:-)), however your use of but indicated to me a conflict.
That was my point.:-) There is no contradiction when it comes down to civil liberties. The AC/troll that I responded to was trying to point out that the ACLU does not do this.
Yup, this is becoming a fragfest!:-)
The ACLU supports the free-exercise of religion by individuals. They don't support the government influence in the establishment, endorsement, or support of a religion.
I'm not clear about your point about free speach versue free association.
