I was under the impression while I had T-Mobile and AT&T that I could buy an unlocked phone at any time but if I bought the locked version it was 50% cheaper than the unlocked version. Now when I called and asked for my unlock codes I never had a problem getting them. I used my T-Mobile phone with AT&T for a long time because it was a better phone.
Also if you are having a problem with your service and the phone company is giving you grief and you want out of it. The Better Business Bureau is your best friend. I sent an email to Cingular through the BBB and with in a 3 week period I recieved a call from the presidents office of Cingular with a message that my plan was terminated and I could pay month to month for as long as I wanted. This was 3 months into a 2 year contract. I cancelled in the next few months because I couldnt talk on the phone at home. They never asked for any fees or even the phone back. I agree all phones shuold be unlocked but I have never experienced any problems with it. If you are paying for 3 different cell carriers I ask you WHY? Unless you really need it or have a really nice expensive phone that you are taking international why do you need to switch back and forth between companies every day in the US?
http://en.wikipedia.org/wiki/Nucleosynthesis its called nucleosynthesis. The reaction chains that fuse in the sun are called nuclear reaction networks. There is a lot of information available on this but Wikipedia gives a nice overview./
As an astrophysicist I feel I should comment. First of all, 70 years of computer simulations later.... we are just beginning to be able to model a supernova with high enough resolution that we can "kind of" fit the observations without contrived scaling factors. This is also only being done in two dimensions and for the first few microseconds of a supernova. Models that hardly include all the physics involved are too much for the modern computational machine. Everytime we run a new model that includes more physics, they fit the data better and better. It is this way we discover what physics matters in the actual explosion. Since we cannot COMPLETELY model anything in real life on a computer all simulations are hand-wavy.
Second, developing theories is very important. You use all of the available data and create a theory that can be tested and describes the current state of what you are studying. The real test of a theory is if it stands up to scrutiny. IF the "standard model" was so vague that no meaningful tests could be performed to prove the theory incorrect then it is a bad theory. Scientists prove things wrong, that is out job. We find situations where the current models do not describe the observations. That is scientific progress. We adjust our theories and learn about new physics. If gravity wasnt tested we would still be using Newtonian Gravity rather than General Relativity, which is still being worked on today (Gravity Probe B).
Lastly, Astronomers have never observed a 150-200 Msolar supernova before. This is the first time we are able to look at what might have happened when the first stars formed. If we had seen a whole lot of these and had a perfect unified model then we wouldnt have to do science or discover things anymore. This is an exciting time as we have the most advanced instruments built by humans peering into the early universe discivering where we came from. I am always excited about new results, whether they be proven wrong or not, because we are always one step closer to understanding the world in which we live.
