Advanced Quantum Mechanics
From Tardis Wiki, the free Doctor Who reference
Advanced Quantum Mechanics was a book of advanced quantum (TV: The Day of the Doctor) and temporal theory (PROSE: The Day of the Doctor) that the Eleventh Doctor was reading when Clara Oswald entered the TARDIS on her motorbike after her day teaching at Coal Hill School. The dust jacket of the book had images of the TARDIS in its police box shape on both the front and back covers. (TV: The Day of the Doctor)
The Doctor had spent several days searching for Wally in this book. He eventually began to suspect that not every book was a Where's Wally?, and resorted to reading the "boring words". (PROSE: The Day of the Doctor)
