The Bohr model of the atom still serves but has been largely replaced with a quantum model. Search the Web using terms such as quantum electronics, quantum electronic device, electron tunneling, etc., in your search. Here is one possibility: point your browser to www.scientificamerican.com and do a search for electron tunneling (hint: search by concept, not by keyword). What can you discover? What kinds of developments, devices, and new products could quantum physics bring to the table in the future?
