Why Theory Matters

There is nothing so practical as a good theory.

Understanding the mathematics behind implementations enables:

  • Debugging — recognize when algorithms misbehave

  • Optimization — know the theoretical limits

  • Security — understand attack surfaces

  • Innovation — extend existing techniques
