The development of quantum theory, which started early last century, has had an impact that can hardly be overestimated. Within the fields of physics and chemistry, it has been a true game changer; but its impact is broader than this. Our new knowledge about the nature of matter has had vast implications for our understanding of nature itself. And quantum theory has brought about new technology – such as microscopy and metrology with unprecedented resolution, lasers, spectroscopy, nuclear magnetic resonance imaging, and semiconductor-based technology, to name a few.
