Quantum mechanics is highly accurate and is used to run modern technologies like atomic clocks.

Even though it sounds weird, quantum math is incredibly accurate. It is so precise that it matches real-world tests to within one part in a trillion. We use this exact science every day. It runs the cesium clocks that set global time, powers the lasers in barcode scanners, and makes the MRI machines in hospitals work. Without it, your smartphone would not even exist.
