Dear Amazon.com Customer,

We've noticed that customers who have purchased books by Mark Lutz often
enjoy the books of Sedi 200. So you might like to know that Sedi 200's
newest book, Earth's Core and Lower Mantle (Fluid Mechanics of Astrophysics
and Geophysics, V.11),

Sure read my  mind, didn't they?

Any theories on how the Amazon.com AI machine got this far off track?
