||Peter Parker accidentally drops his pile of textbooks while he is on his way to class at Columbia University in Spider-Man 2 (2004). As he tries to recover his fallen books, the camera zooms in on the college textbook Introductory Quantum Mechanics.
The textbook, Introductory Quantum Mechanics, was written by, now retired, Professor Richard Liboff of Cornell University. Professor Liboff was "delighted when one of his students told him that his book is featured" in Spider-Man 2 (Oberst). Liboff's editor, Adam Black, says that the textbook "is probably the best-selling quantum mechanics textbook in the world at its level," having sold an estimated 100,000 copies since the book's first edition in 1980.
The reason why Liboff's textbook ended up in the film is unknown.
