Negative Positive
Title: Long time since I read this...
Review: ...but, it remains a vivid memory; especially his research on 'pleochroic halos' (sic), concerning which I've never heard a persuasive argument against. Dr Gange presents difficult scientific concepts in layman's terms. I found his arguments well reasoned and persuasive; music to my ears, perhaps. A little read book that is rightly quoted by subsequent technical researchers.
Is the review positive or negative?
