👉 "Killed math" is a term used to describe a situation where significant mathematical concepts or theories are no longer taught, studied, or considered relevant in modern education and research. This often happens when new computational methods or technologies render traditional mathematical approaches obsolete, such as when symbolic computation and computer algebra systems can perform complex calculations that were once done by hand. As a result, students may miss out on foundational understanding of mathematical principles, and researchers might overlook important insights that could have been uncovered using classical methods. This phenomenon can lead to a disconnect between theoretical knowledge and practical application, potentially stifling innovation and deepening the divide between mathematical theory and its real-world applications.
