Radio waves at the Larmor frequency (predicted by quantum mechanics) flip these spins. When they relax back, they emit signals that a computer reconstructs into 3D images of soft tissue. Unlike X-rays, MRI uses no ionizing radiation, making it safe for repeated use.
Because satellites move fast and sit further from Earth's gravity, their clocks tick at a different rate than ours. Engineers must apply Relativity formulas to sync satellite data with your location on the ground. 3. Medical Miracles Applications Of Modern Physics
Here is how the "weird" science of the subatomic and the cosmic shapes our daily lives. 1. Electronics and the Silicon Revolution Radio waves at the Larmor frequency (predicted by
