QUANTUM MECHANICS: A THREAD RUNS THROUGH IT ALL

Those of us who learned quantum mechanics, we love this notion that quantum mechanics is going to save the world and rewire the grid.

Quantum mechanics is the common thread linking many fields of science in the microworld into one field called nanoscience on which nanotechnology is based. This thread runs not only through different scientific disciplines in the microscale, but also runs through the whole scale from microscale (including nano) through macroscale. As we emphasized through the correspondence principle throughout this book, classical mechanics is just an approximation of quantum mechanics in the limit of large quantum numbers. In other words, classical mechanics is the quantum mechanics of macrosystems. In this chapter, we will explore this thread along different disciplines of science.
