Accuracy, Precision, and Significant Figures, 6. Rotational Kinetic Energy: Work and Energy Revisited, 71. We also acknowledge previous National Science Foundation support under grant numbers 1246120, 1525057, and 1413739. In the following chapters we shall touch upon several Quantum mechanics can be thought of roughly as the study of physics on very small length scales, although there are also certain macroscopic systems it directly applies to.

Introduction to Vision and Optical Instruments, 213. As with water molecules in a stream, we do not notice individual charges in the current through a lightbulb, because the charges are so small and so numerous in the macroscopic situations we sense directly. Limits of Resolution: The Rayleigh Criterion, 221. Because these objects are smaller than we can observe directly with our senses and generally must be observed with the aid of instruments, parts of quantum mechanics seem as foreign and bizarre as parts of relativity. Maxwell’s Equations: Electromagnetic Waves Predicted and Observed, 205. Certain aspects of quantum mechanics are familiar to us. Conductors and Electric Fields in Static Equilibrium, XIX.

While we cannot see the individual water molecules in a stream, for example, we are aware that this is because molecules are so small and so numerous in that stream. quantum mechanics [1] well if you aren't Newton’s Third Law of Motion: Symmetry in Forces, 26.
