Ask HN: What is the hardest math you used in a project?
What is the most difficult or beautiful math that you used to solve a real problem? Ive done the C++ challenge to calculate pi deeply and quickly; also finding prime numbers. Those were fun to do as a beginner. Much more recently, IBM qiskit has a bit too advanced math for me. Over my head; but theoretically i did use it lol. I cant say i understood it. I imagine for example that some implementations were made fast enough to meet a requirement with some very hard algorithms.
