Anyway, everything everyone has been posting here (especially Nebelpfade) has been discouraging me to pursue a career of Computer Science something I really am passionate about.
Don't get discouraged! If you are passionate about science, then go and do it. Don't let the fact that some people on a message board, or some book you read said you cannot be Orthodox and a scientist convince you that it is so. I used to have a deep passion for science, and I wanted to be a paleontologist, but my love for science was beaten out of me by the public school system (which I later found out my district was greatly influenced by Fundamentalist Protestantism to remove science (the interesting stuff) from the class rooms. Well it worked, and I never went down that path, and part of me regrets to this day. (though it was not really a fault of mine) I probably wasn't bright enough to do the science anyways, but there is no reason you're not, and no reason you should NOT become a scientist.
I also think you might be misreading a few posts here. I don't think everyone was trying to discourage you, only point out some false assumptions about Einstein, and some others. Too many religious folk repeat these myths about Einstein and Hawking being traditional styled believers in God. And for many people that gets to be a bit annoying because it's simply not true.
I'm familiar enough with Heorhij's posts at least to know he wouldn't try to discourage you from this path I can't say for others, but I think most were just trying to "debunk" certain myths about people. Of course these myths go in both directions as plenty of atheists proudly assert that Carl Sagan was an atheist, when in fact he was not. His widow for the last 5 years have been going around trying to "debunk" that myth as well, much to the anguish of many proud atheists who would claim Sagan as one of their own. (as previously said he was a classic agnostic)
There are plenty of scientists who are religious, traditionally religious, even Orthodox Christians. Ken Miller is a traditional Catholic and is a fantastic scientist. Don't be discouraged. One can be a scientist and keep their faith. The trick is one has to DO the science and use the scientific method which many religious people simply are not willing to do. But I personally know a hydro-biologist who is Orthodox, and he's kept his faith without a problem. Science is a wonderful endeavor, and if you have the passion for it, the love for it, and the ability to do it, then go do it. God gave us our brains, and never intended us to shut them off. Science is beautiful, and the knowledge we have of our world through science has given us a far grander picture of the cosmos then anyone ever imagined. For some this convinces them there is not God, for others it strengthens their faith. Many scientists are non-theists, agnostics or atheists, but many are theists, or Jews, Muslims, Christians, Hindus, etc... That's what is great about science. Anyone willing to go do the science can do it. And it matters not if they are black, white, male, female, religious or non-religious. If they are willing to go do the work, and do it well, they can do it. You can to, and keep your faith as well.
Don't let religion, or someones interpretation of religion keep you from something you love doing. That would be horrible, and I don't think anyone here intended that at all.
