Greetings, all. I've spent most of my life (being 24 now) longing for the sort of clarity provided by rationalist thought, but only discovered a few months ago that there was such a thing as empirically verifiable truth accessible to me, and that it was possible to build a belief system with solid foundations. I'm still going through the resulting lengthy process of reassessing my beliefs in light of actual evidence.
My partner recently introduced me to this site, and I dived right in - only to hit a concrete wall. My mathematical skills, unused since school, have completely atrophied, to the point that I can't even follow An Intuitive Explanation of Bayesian Reasoning (my work computer's refusal to load applets not helping). Since a significant proportion of the Sequences seem to rely on at least a basic understanding of probability theory, I am rather stuck. With this in mind, I'd like to ask for recommendations of material which will help me grasp the essentials necessary to fully understand Less Wrong.
I realise that asking for things I might theoretically find through sufficient Googling sounds lazy, but on the other hand the fine people here might know the best-written and most effective ways of covering the necessary ground.
So: what areas of mathematics and probability theory do I need to cover in order to be able to follow the material on Less Wrong, and do you know of any good sources for learning them, assuming I'm starting from zero?
I have a unique way of explaining Bayes' Rule that has so far helped zero people out of the one who has looked at it. The advantage is that it is very different than other ways, so if those are confusing, you could give it a try.
