well if thats the case I'd recommend studying HRK (haliday, resnick, krane)'s "physics" to get caught up on the basics. then studying a book on vector calculus Thompson has a decent introduction. Then move on to the more advanced stuff such as a book on mathematical methods (Boa's) and then quantum mechanics, and some mechanics. From there you could study advanced quantum mechanics and then Quantum Field theory. And then you could study particle physics. It would probably take 2 years to get through all that and actually learn it, but if you want to you can do it.

So I was playing around with the idea of a relativistic rocket equation, and in the process of deriving it I ran into a differential equation that I can't seem to solve. v_e dm= m(1+mu^2 (gamma)^2) du its first order but I can't seem to figure out how to solve it, m is the rest mass (which changes because its a rocket) u is the velocity of the rocket, and gamma is the relativistic factor gamma= (1-v^2/c^2)^(-1/2) any help solving it would be greatly appreciated, I tried seeing if I could use integration by parts on it and then subsequently differentiating, but that method seemed dubious at best.

huh, I wonder why that works

actually the hubble radius is around 50-100 billion ly, do to inflation

crap I must leave this thread now to avoid exposing my eyes to spoilers (I need a bit of entertainment with my philosophy). However it does appear that in the first part of the book (up to where Ive read) she does argue that her philosophy should not be taken to far. For instance Dagny and Reardon always felt that they were missing out on love, and were at times miserable because of this. I don't know if this is solved later on or not, but it does seem to indicate something with Eddie almost as the temper to Dagny's actions. This is shaping up to be in my top two books of all time, along with stranger in a strange land.

thats unfortunate, I'm on page 200 or so and it seems to still be getting better (although it is altogether too drawn out, its very interesting)

hah you know its funny right now I'm reading "atlas shrugged" by Ayn Rand and the entire book is about why that sort of philosophy makes for a very bad society. however I suppose that in the end its a moral dilemma between the philosophy of collectivism and the philosophy of objectivism. I highly recommend the book by the way.

well again the average citizen would have only gotten the benefits of extra jobs in the area around the oil supply, and of course added industrial centers for processing andexporting the oil, which then leads to additional buisness ventures etc. In the end it doesn't matter a whole heck of alot whether a russian or an american own the oil fields to the average american, out of curiosity how many of america's natural resources, factories, and buisnesses do you think are owned by americans? Furthermore in america the government would not have the right to sell the oil fields in most cases, only the peple who discovered the oil/ owned the land it was under would have that right in most cases. In the case of Iran the Shah owned the land (him being a type of king) and as such the rights to the oil were his. Or it was something else related to his legal rights in the matter truthfully I do not know. But again it doesn't make much difference whether or not the oil was owned by an Iranian. I wonder however what the benefit of the nationalization of the oil has been to the Iranian people, and what extra benefits they get from the nationalization of their oil fields. I wouldn't be surprised if the only difference the Iranian people saw was a larger arms budget. I wonder how many popular leaders are threatened with impeachment then dissolve the parliament, have lost most of their allies, and have the communist party angry with them subsequent to nationalizing industries.

meh, while the gap between rich and poor has grown considerably since they allowed foreign investment. there are certainly alot more rich people than there were in the communist days, and the poor have alot more now than they did then.

the problem with your thinking is that you are only looking at the soviet union and china's personas in reality things were far worse than they appeared. for instance the Soviet Union's GDP was only about a fourteenth of the US's and yet they maintained a military that was supposed to be on par with America's? they spent somewhere between 15 and 30 percent of their GDP on defense, and even then they couldn't afford to properly train soldiers, (in the age of smart bombs and missles many soldiers weren't even allowed to fire a missle in training as it was to expensive) the goal of all this was to match the US in percieved military power, by purchasing enormous amounts of hardware, and then neglecting it. If you look at soviet erra cars you can also see how cheaply they were made. As for China, ever since they opened their doors to the west their standard of living has been rising, in fact their economy is set to surpass that of the USA by 2020 in terms of purchasing power., clearly capatilism benefited their country.

bombus if you would read more carefully you'll notice that I was drawing a comparison between the arguments of anti-semitism, and the arguments placed against the west by various anti-western groups around the world. as for the mosaddeq I will direct you to this section from wikipedia. http://en.wikipedia.org/wiki/Mohammed_Mossadegh As you can see he wasn't exactly well liked at the time, and while it certainly wasn't the job of the US and Britain to deal with him, I would venture to guess that the coup would have happened anyway. and what does that have to do with it? they could have been given the worst deal on the planet and it still wouldn't matter, the rights were sold and maybe the government got a raw deal (which was composed of an autocrat at the time) the people got the same benefit that they always would have, more jobs. Now if you were a car salesman and you let a customer negotiate you down to a price that was far lower than you could mae money off of, but you still old it to him. would you show up at his house the next day and take it back?

bombus any evidence to say that anti-western elements in IRan came after Iran was trying to become like us? the shah tried to westernise the country and was eventually overthrown, if you want to overthrow a pro-western leader; blaming the west for everything isn't a bad idea. It's also not that hard to create anti-western sentiment using anti-semetic arguments such as "why do they have all the money, they must be taking advantage" "they use their wealth to keep power" etc. As for nationalization, it may have originally been Iranian oil, but british companies payed for the rights to use the fields, they built infrastructure and carried out all of the tasks required t start exporting oil. Ad then the Iranians took the fields back. This is similar to selling the farming right to your lands, allowing the person you sold the rights too to care for the crops until just before they are supposed to be harvested. And then kicking the farmers off your land and then selling the crops that they grew.

hmm you do realise that that doctor was focusing primarily on "alernative" autism treatments, not mainstream autism treatments and science.

you could also say that certain power hungry groups in Iran used the west as a scape goat for all of Iran's problems and are currently maintaining their own power through the illusion that they are taking action against the west. such a stance would be reasonably well supported by a comparison with other countries such as NAZI Germany. but then again maybe the jewish bankers really did cause germany to lose WW1 because of te style of banking they used etc.

I think the million monkeys theorem comes into play here, if you consider all of the highschool students in the world who write essays on "the causes of WW2" you probably have all the paragraphs for every 5 page paper that could ever exist on the subject already written. Software that looked for plagiarism in a database that encompassed all of these papers would surely indicate that there is simply a world wide paper trade, and that students find it easier t track down papers written 3000 miles away than to do research.

bascule if the lazer anti-missle systems ever become powerful enough MIRV's and the like will become useless. bombus its interesting you only critisize the west for militarism, when the soviets spent a far larger amount of GNP on military expenses than the US ever did, Just like you overlook the overbearingly large number of military men in the soviet cabinets.

it would still be requiredin the day to day, its just that you an use alot of lovely approxiations to cover for it, for instance when you are working out the trajectoriesof two rubber balls that collided, do you really need to know what was happening at the atomic scale to find your answer.

I think the type of plagiarism I mentioned is really undetectable at the teachin level and can only be noticed by the students. However you mentioned before that you suspected a number of papers had cut and paste sections from wikipedia by the general style. Is it possible that some of the authors edit wikipedia frequently and as such the style is starting to blend into there own writing? or that they are influenced by reading wikipedia so much?

like I said though, the majority of fraudulent papers are writen uniquely by a friend or some such for a fee. its impossible to spot any plagiarism from that source as each paper is unique.

meh, even if the web sites were shut down it won't help, as in my experience the majority of purchased papers are from other students. Its not to difficult to find someone willing to write a paper for $20-30. While I have never made use of this or participated in it, I know several people who do it for some extra cash.

there already is a unification between SR and QM

yes its a feature that you have to activate in control panel however. Also you kknow you can scroll with the arrw keys or using a two finger motion right?

good god this thread is old, but at the time It was working on te project I contacted a plasma physicist who said that the plasma could not be using internal magnetic fields to keep itself contained. At the time he suggested that it could have been some sort of burn front that we were viewing and not a contained plasma (a true pasma). however due to the respose to magnetic stimulus I am a bit dubious of this hypothesis, however its still possible that the metal had been vaporising and then ignited in that region. My personal hypothesis is that the plasma got caught in that region due to some sort of pressure difference between the top and bottom of the plasma. However I eventually abandoned the project due to an inability to test for any of the possibilities.

you can get it to be quite stable using a glass bottle. (when the bottle is still right side up). let me dig up some pictures

I didn't say that there was a logic behind it, just that fewer people per capita are going to college. Which indicates that there is a serious flaw in the system. although I would disagree that the degree has been diluted to the equivalent of a highschool degree in the 60's
