摘要:

Interest in the physics of condensed matter at size scales larger than that of atoms but smaller than that of bulk solids—so‐called mesoscopic physics—has grown rapidly over the past two decades, but it stems from much earlier beginnings in diverse disciplines. Indeed, nanostructured matter apparently had its genesis with the Big Bang. The structures of the earliest meteorites suggest that matter formed by the condensation of atoms into nanoscale clusters that then aggregated into larger masses under the action of gravity. Many examples of natural nanostructures can be found as well in biological systems from seashells to the human body.

摘要:

Each day in Detroit and Seattle and a score of other cities around the world, dozens of cancer patients report for neutron treatments of tumors resistant to conventional photon‐based radiation therapy. Few, if any, of these patients know that the healing radiations are being produced by a cyclotron operating in accord with basic principles first promulgated some 60 years ago in a journal, thePhysical Review, which they also know nothing of. And Ernest Lawrence and Stanley Livingston, as they wrote their pioneering 1932 paper, spoke of the relevance and need for such a device in the study of the atomic nucleus, but at least in their earliest papers, no thought of a future benefit in the treatment of cancer is considered.
