Okay, I've read through the last 6 or so pages since I was last here, and there are a few things I wouldn't mind adding.
Some minor ones first.
The two theories in physics that "disagree" with each other, General Relativity and Quantum Mechanics, yes that is a problem. In essence, General Relativity works wonderfully for large objects (larger than an atom), and Quantum Mechanics has very different rules and laws to govern the behaviour of small objects (sub-atomic particles). The problem is when you get an incredibly small object with incredible mass, such as a black hole singularity. Which laws do you use? General Relativity because it has a huge mass, or Quantum mechanics because it is very small? Problem...
This lead to the search for a Grand Unifying Theory of Physics. The best candidate at present is String Theory, as mentioned previously. I know we have danced around describing it, as it's quite complex, but a simple (?) explanation is this: String Theory proposes that, smaller than the known subatomic particles (electrons, photons etc), there are the smaller particles which make up the known ones. These particles are refered to as "strings", as that is the shape they take.
These strings "vibrate" at different frequencies, giving rise to particular properties. They are sometimes closed loops, and sometimes open-ended, resulting in the variety of particles we know and don't know, including predicted Gravitons, sparticles, and potentially dark matter.
String theory goes on to predict up to 11 dimensions, and the possibility that our Universe is located on a plane travelling through the spacial element, with other planes moving through as well (leading to a possible explanation for the Big Bang, amongst other things, such as the reason for gravities extreme weakness). Fun stuff.
Okay, string theory down. That was very basic, but I'm sure no-one wants to get too far into this here.
Mary as the Immaculate Conception. Yep, very true. Although it is not as emphasised in most Christian churches as much (mostly in Catholicism, for the record) as it is in Islam. In fact, the Koran has far more references to Mary the Holy Mother than the Christian canonical Bible does.
While I'm on that, it is probably best to remember that religion is really the human control on spirituality. That can be a very good thing, giving boundaries, and a defined sense of belonging, as well as giving a constructto the form of worship taking place (set practices for prayer and ritual, for example). But it is also a dangerous thing, when such boundaries are enforced upon the followers, and is used to control, or justify behaviours. I'm sure most here can see that, and it's actually not my point here.
My point is that what is thought of as the true Bible (for example) is just what has been chosen to be presented by a group of people, and the reasons are not always spiritual in nature. Basically, what is in the Bible is only part of the story. There have been many alternative religious and spiritual writings that were denied canonization by the Council of Carthage, and the reasons ranged from not having enough evidence of the particular writings validity (such as not being written in the right timeframe), through to emphasising the wrong things (to a Christian viewpoint), supporting the wrong political ideals, through to giving tacet permission to completely unacceptable acts (for this, there are examples of a longer version of Genesis... I'll talk about that if people ask, but if not, I won't. It's about the gaps in the canonical text, and I don't want to offend anyone).
With regard to Mary, it is believed that the reasons the stories about her were kept out of the canonical Bible were simply that they took the emphasis away from Jesus (taking the narrative off tack, as it were). Within the Islamic faith, Jesus, although important, is a secondary figure to Muhammad, so taking emphasis off him to talk about the miracle of his mother is fine. Other texts to give a greater feel for the comptemporary writings are found in the Dead Sea Scrolls, and the Ethiopian Bible, which is based on an earlier (pre-Council of Carthage) version. Again, fun stuff.
Now Dawkins and his agenda. I don't think it's hard to see that his take on religion in general is pretty negative, and he makes no attempt to hide it. And I agree with Jenna that his approach is quite ironic, with his very evangelical attempts to convert those around him and beyond. That said, I disagree wholeheartedly with everyone here who has said that his purpose in this interview is to make believers look stupid, ill-informed, or bad in any way. As I mentioned before, he has other shows about that, this one was purely about Darwin. What he was doing was making people who refuse to accept established scientific fact, even when presented with the evidence, even when it can be shown to be congruent with their faith, even when every argument they have is defeated, these people who insist on speaking to children, claiming to be protectors of childrens educations when refusing to be educated themselves, that is what he is showing up here. Yes, her belief has helped shape her views here, but her faith is not why she was being interviewed. She was a very vocal proponent of a highly flawed educational standpoint, requesting theological concepts dictate scientific classes. That is simply wrong, and she is one of many who ask for such a thing to occur. So the point it not "she believe's in God, what an idiot", it is more "she has no ability to think critically, no ability to differentiate between theological and scientific concepts, and wants to thrust such igonrance on our young, what an idiot". Her believing in God is not an issue, her lack of understanding of the concepts she is fighting for and against is.
I think that's it for now...
