Tak, to schemat frenologiczny.

Poza tym łatwo to sprawdzić w wikipedii:

"The film Pi depicts the main character, Max, outlining a portion of his
skull according to a phrenology chart and proceeding to drill into that
section to destroy a part of his brain that contained important
information of a mathematical sequence that he thought nobody should
know."

przepraszam, że cytuję wikipedię (bo to niesmaczne), ale...

ale kurde, wiesz, ta scena w tym filmie bardzo mi się podoba.

Pozdrawiam :)
