Academic debates Memes

The mathematical notation "0 ∉ N" simply means "zero is not an element of the set of natural numbers" - a fact that's sparked more academic fights than the department coffee budget. Mathematicians have been bickering about whether zero belongs in the natural numbers since before calculators were cool. Some textbooks include it, others don't, and somehow we've built modern civilization on this shaky foundation. The perfect metaphor for politics meeting mathematics - absolute certainty about things that are completely arbitrary.
