I read a book about Turin (The Emperor of Scent) that I really enjoyed, so I was excited to find this on my library shelf. Turin puts me in mind of Feynman in both erudition and wry hilarity. This scientist can write circles around most writers. The topic, the biological mechanisms by which we perceive scent, is fascinating. The writing, may I say again, is scintillating. The physics slowed me down some, but Turin made it more accessible to me than anyone since Feynman. I learned and laughed in equal measure. I find Turin's theory of the human spectroscope compelling, but like him, am content to wait for proof. Highly recommended.
