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 papers 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.
When I was growing up in the 1950s and spending summers on my grandparents’ farm in North Carolina, I became strangely aware that we were living in truly radical times. I say radical because that word comes from Latin radix, meaning “root.” I could sense that the roots of our civilization were shaking beneath us, even though the civilizational tree still seemed strong and healthy. Problems with the roots implies problems with the tree. Dealing with that requires some “radical” thinking, that is, thinking directed to the root of things. This Word and Fire web site hopes to take some constructive steps in that direction.Continue reading “Roots to remember”
I intend to start some posting to this site, and science news is a good place to start. For science entangles the ordinary everyday course of our lives with inconceivably exotic and almost unimaginable events of our vast yet comprehensible universe. The collision of two supermassive black holes recently detected by the LIGO/VIRGO collaboration of gravitational wave astronomy made news articles in both Nature and Science and, additionally, had two NewYork Times articles( 1 and 2) about it.Continue reading “Black holes and all that”
Richard Feynman (1918-1988) was one of the most highly regarded physicists of the 20th Century. He had an uncanny knack for getting to the heart of a problem with simple language and insights. His work had impact not only in fundamental physics but he posed challenges to explore new areas such as nanotechnology or quantum computing, and also, perhaps surprisingly, science and religion.Continue reading “The Feynman Challenge”
