I will probably start by reviewing some of the papers he mentions. Then I will reach out to my friends in the scientific community. I'm sure they will be totally thrilled to answer all my dumb questions. Then when the dust settles I might reach out to one of the people he mentions who happens to be a friend of an acquaintance. Whatever questions remain might end up on StackExchange. [1][2][3] Oh and I might ask some questions here.
