Should the word Boolean be capitalized?
I notice that many online articles geared toward programmers refer to boolean variables, which are variables that have only two states: true or false. Is this correct usage? I'd contend that the "b" in Boolean should be capitalized because the term Boolean is named after mathematician George Boole.
More generally, are there any grammatically correct examples of terms named after someone that are no longer capitalized?
