The capital city of Qatar is: Doha

My experience in finding information on these countries was....
The search engine was quite useful and quick compared to the library.
However the library wasn't exactly slow. The worst part in dealing with
the library was actually getting up the gumption to go there in the first
place. It seemed very inconvenient. Once there though I was able to use
my 4 years of dealing with this particular library to my advantage. It
only took 15 minutes once I was there. So in this case the library was
more efficient. Like I said though it took a lot to get myself to go (a
disadvantage). The problem I had with the search engine was trying to find
the specific page with the necessary info out of the 100,000's there.
That's why I preferred the subject tree because it seemed to group things
together and lead me to refine my search for me, instead of me knowing
exactly what to type. When I do searches in my own time (very little),
I tend to use Yahoo anyways.
The simple experiment
he performed was:
Feynman now believed that he had the solution, but to test it, he dropped
a piece of the O-ring material, squeezed with a C-clamp to simulate the
actual conditions of the shuttle, into a glass of ice water. Ice,
of course, is 32 degrees F. At this point one needs to understand
exactly what role the O-rings play in the solid rocket booster (SRB) joints.
When the material in the SRB start to heat up, it expands and pushes against
the sides of the SRB. If there is an opening in a joint in the SRB,
the gas tries to escape through that opening (think of it like water in
a tea kettle escaping through the spout.) This leak in the Challenger's
SRB was easily visible as a small flicker in a launch photo (see photo
to left.) This flicker turned into a flame and began heating the
fuel tank, which then ruptured. When this happened, the fuel tank
released liquid hydrogen into the atmosphere where it exploded.

My experience in finding this information was again similar to that of before. The search engine was useful with a pluthera of information, but much of it was irrelevant to my search. With the subject tree, I was pointed in the right direction and given many useful links to refine my search. It took me approximately twice as long to use the search engine. Also it is interesting to compare the 2 styles in that I used the same exact quote of "the wolf" for both searches. This would lead me to believe that if you are not exactly sure how to limit your search, then the subject tree is the best way to go. Of course I speak from limited personal experience, but experience just the same.
