Two different readers have now suggested that the video clip of me singing the Riemann Hypothesis

song has some strange hypnotic power. Sample (from a reader in Canada):

“Derb, I don’t know if it’s your haunting delivery … or if it’s the clever

composition of the lyrics, but I CANNOT GET THAT SONG OUT OF MY MIND!! For

the last three days all I have heard, playing over and over again in my

head, is ‘…and-their-DEN-sity’s-one-O-ver-two-pi-log-TEE.’ I only watched

the clip twice! Could this be some sort of subliminal psychological

programming to get viewers to buy your book? … Must go to bookstore …

must go to bookstore…”

OK, I confess: I had supernatural assistance in making the clip. To be

exact, I prepped for the shoot by channeling Berhard Riemann for an hour beforehand. Thanks, Bernie.
