I have been following Prof Stoermer’s videos preceding this book and pre-ordered it on that basis. I to read it but am a bit disappointed and disturbed that there is nothing by way of an index or footnotes, and no reference I can find that they are available elsewhere. My 3 therefore, has nothing to do with the substance and will update this review after I read it. But I don’t understand the absence of such material.
