Welcome to my web site with links to material related to science and personal interests. Click on one of the links above to get to the various categories. Click “About” to see why I named this web site “Word and Fire.” Click on “Physics” or “Publications” to see my interests and work in physics. “Personal,” “Photography,” and “Poetry” deal with personal interests. “Sources” is my other web site, with much duplicate material, which is being migrated here.
