noun ho·mo·ge·ne·i·ty \ˌhō-mə-jə-ˈnē-ə-tē, -ˈnā- also ÷-ˈnī-; especially British ˌhä-\
Definition of HOMOGENEITY
1: the quality or state of being homogeneous
2: the state of having identical cumulative distribution function or values
I found this word in the reading for the week Universe Strikes Back by Ellen Lupton and I’m thinking she means the second definition where there are identical functions someone can have within them selves.
