The Math Department.

When I was at UBC, studying math, some fancy board of directors decided to remove all the chalkboards and replace them with whiteboards.

The math professors were furious -the UBC math department has a reputation of being a bit stodgy. They launched a campaign to keep the chalkboards. They didn't want projectors, or whiteboards. They needed their old chalkboards. They referred to the chalkboards as "Weapons of Math Instruction".

It was successful. They got to keep their chalkboards.
